Martian Emperor

Voiced By: Djimon Hounsou

The ruler of Mars. He was the one who ordered that Mars be quarantined due to the planet being infested by intergalactic parasites.

• Aliens Speaking English: Though according to him, he's speaking fluent Martian.
• Blatant Lies: Claims to know what Viltrumites are yet doesn't seem fearful at the mere mention of them and just looks over at one of his subordinates.
• From Bad to Worse: He finds the astronauts to be a threat on Mars because of the possibility that they may be possessed by the Sequids. The situation only becomes worse when Invincible forgets one of the astronauts and the forgotten astronaut becomes a host for the Sequids.
• Gilligan Cut: The moment he makes it clear to Invincible that he will kill the astronauts, the next scene cuts to Invincible helping the astronauts escape an army of Martians.
• Hero Antagonist: He has a justified reason as to why he feels the need to kill the astronauts, wanting to prevent the Sequids from taking control of their bodies and potentially using them to conquer the planet. While it is a morally ambiguous act of heroism, Invincible refuses to allow the Emperor to kill them because they are innocent people, leading to the hero fleeing Mars with the astronauts while the Martian Emperor sends his army of Martians to execute them.
• Humanoid Aliens: He and his people physically look human except for their brown skin, red eyes and elongated skulls.
• Innocent Aliens: Downplayed. He and his people only desire to protect their planets from the Sequids, but they are willing to use extreme measures of committing murder to innocent astronauts to do so.
• Mr. Exposition: He provides Invincible the origins of the Sequids and as to why he needs to have the astronauts executed.
• Murder Is the Best Solution: The moment the astronauts arrive on Mars, the Martian Emperor immediately desires to have them executed to prevent the Sequids from using them as a Puppeteer Parasite. Although he could have protected them from the Sequids by helping Invincible take them back to their rocket, the Martian Emperor continues to oppose against Invincible in killing the astronauts even though Invincible is desperately trying to save them from a Martian army.
• Pragmatic Hero: He is willing to have human astronauts be killed in order to make sure that the Sequids don't possess their bodies.
• Puppeteer Parasite: Defied. His main motivation of wanting to kill the astronauts is to make sure the Sequids don't possess their bodies and become a threat to the universe.
• Quarantine with Extreme Prejudice: When the Sequids landed on Mars, he ordered that the entire planet be quarantined in order to prevent them from gaining a host. Those orders include the immediate execution of any foreign visitors to Mars that are susceptible to Sequid possession.
• Self-Fulfilling Prophecy: By ordering the astronauts' execution, Invincible is forced to try and save them by escaping with them in a hurry. Unfortunately, Invincible unwittingly leaves one astronaut behind^note A martian rebel shapeshifts into one of them to hitch a ride out of Mars who indeed ends up becoming the host to the Sequids while everyone else is distracted. The Martian Emperor would have probably prevented the Sequids from possessing the forgotten astronaut (and likely caught the impersonator in the process) if he had just agreed to let Invincible and the astronauts return to Earth.
• Shoot the Dog: Although it is evil to kill the astronauts, the Martian Emperor is only doing it to protect Mars and the entire universe from the Sequids.
• Underground Alien Civilization: The entire Martian civilization is currently underneath the surface of Mars, and it's implied that this is because of the quarantine instituted by the Emperor to contain the Sequid threat.
• Well-Intentioned Extremist: He orders the astronauts to be killed so they wouldn't be hosts to the Sequids. He has damn good reason to be afraid of them.
• White-and-Grey Morality: Invincible acts as the "white" by wanting to protect the astronauts from the Martians. The Martian Emperor and his army act as the "grey" for wanting to kill the astronauts, but only to prevent the Sequids from taking control of their bodies.

An intergalactic organization that helps test planet defenses for various alien threats.

• Aliens Speaking English: Despite consisting of various members from completely different planets across the galaxy, every member shown thus far — particularly Allen — speaks perfect English. Though it could just be Translation Convention during the scenes in which Allen interacts with them. It's later Lampshaded when Allen, downcast about being separated from Telia for a long period thanks to the eslcatiag conflict with the Viltrumite Empire, tells Mark he's just in a bit of a funk, then realises he should probably explain the concept of a funk to Mark, only for Mark to tell him the word means the exact same thing back on Earth, which Allen finds weird.
• The Ghost: They don't appear onscreen in Season 1, only being mentioned by Allen. Season 2 onward, however, has them front and center.
• Hero of Another Story: Allen mentions that they've been marginally successful in protecting various planets from Viltrumite invasions. It's implied they have been a consistent thorn in the Empire's side, which is rather impressive when you consider just how powerful an average Viltrumite soldier is.
• Properly Paranoid: Zig-Zagged. The members of the Coalition's council are skeptical that Mark is a so-called "good guy" Viltrumite, with one even openly wondering if he just wants to protect Earth and conquer other planets by himself. On the one hand, they have good enough reason to be distrustful of Allen's assessment of Mark given the track-record of Viltrumites by that point. On the other, Allen isn't wrong to call the council too close-minded given how several members immediately move to completely dismiss the report without fully pondering its implications or at least calling to investigate further; as Telia points out after the meeting, Mark claiming that he's only half-Viltrumite alone is both easily provable and completely at odds with the Viltrumites' rigid adherence to racial purity, a line of thought Allen agrees is worth questioning.
• Pyrrhic Victory: Zigzagged with the Viltrumite War. On one hand, countless systems that were enslaved by the Empire were liberated, several Viltrumites were killed and their planet was destroyed. However, the Coalition lost their leader Thaedus, and there are still 37 Viltrumites left alive, including Thragg, their leader and most powerful warrior. What's worse, they have taken residence on Earth, where they intend to procreate with humans to rebuild their forces, meaning that if not now, but in the future, the Viltrumites will become a problem for the rest of the universe once again.
• Reasonable Authority Figure: Allen was worried he'd get fired for coming to Earth instead of Urath. That didn't happen; offscreen, they asked with concern how Allen survived during his multiple visits because Earth was flagged for having a Viltrumite mole. They also gave permission for Allen to return to Earth to warn Mark about this, not knowing that Mark met the mole... his own father, who nearly beat him to death and killed thousands of people. Allen mentions that Mark's heroism will surely merit interest from the Coalition of Planets, and extends an invitation for Earth to join. 
• La Résistance: They are an organization dedicated to fighting the Viltrumite Empire and helping planets test their defenses. Allen on behalf of the Coalition invites the planet Earth to join, so they'll have reinforcements for the battle to come.
• This Cannot Be!: Like Thaedus, the Council is shocked at Mark being a half-Viltrumite and having fought his Viltrumite father (causing him to abandon his post).
  "Unbelievable."

Thaedus

Voiced By: Peter Cullen

The wise leader of the Coalition, and the first Viltrumite in history to betray his own people. Thaedus is determined to stop the Empire's cruelty at all costs and proves willing to go to some extreme lengths to do so.

• Adaptational Angst Upgrade: In the original comics, Thaedus is somewhat taken aback upon learning the extent of the suffering that the Scourge Virus caused, but nonetheless holds a firm I Did What I Had to Do attitude towards the atrocity and continues to hide his involvement until he's later exposed. Here, he feels so much remorse afterwards that he almost immediately comes clean to Nolan about his involvement in it and has a Please Kill Me If It Satisfies You moment with him afterwards.
• Adaptational Badass: Come the part in the Viltrumite War saga where Thaedus fights with his own hands again after so long, in the comics he mostly fights evenly with one or two nameless background Viltrumites at a time, which did show that Thaedus was still battle ready in his old age but didn't give the impression that he was especially powerful compared amongst other Viltrumites, as he was on the losing side of his fights against the likes of General Kregg or Anissa. In the show Thaedus' showing is much more impressive, with new fight scenes where he takes on Kregg, Anissa and Lucan in rapid succession and holds the upper hand against all of them, while snapping the necks of nameless Viltrumites with little struggle, showcasing himself to be force to be reckoned with even amongst Viltrum's elite warriors.
• Adaptational Nice Guy: He is a good person in the comics yes, but the show makes Thaedus come off as a more approachable and honest leader, made more evident by Season 4 once the truth of his actions come to light. Once he is revealed as the creator of the Scourge Virus, the show goes to further lengths in portraying Thaedus as feeling remorse over being pushed to this solution once he is told the virus wiped out 99% of the Viltrumite population, he gets honest with Nolan afterwards, telling him there is a stronger variation of the Scourge Virus available and that he plans to use it as a final solution if their attack plans fail, also Thaedus offers to be killed by Nolan's hands as a form of repentance, if not Thaedus claims he might kill himself once he sees the Viltrumite menace is truly over. That level of guilt and honesty didn't exist in the comics, Thaedus was only mildly taken aback once he is told the virus destroyed Viltrum to that extent, he doesn't open himself to Nolan, never telling him there's a second strain of the Scourge Virus available, and doesn't offer his life to repent either.
• Adaptational Villainy: Downplayed. He is still earnestly a good guy who wants to protect the universe like the comic, but he is such a Principles Zealot that he has completely shunned any possibility of good from his people and it is implied he was already preparing to eventually betray and kill Nolan, Mark, and Oliver due to their Viltrumite nature as Thragg is quick to realize that Nolan doesn't actually trust Thaedus's word at all in his attempt to appeal to his sanity, whereas the comic never implied that he would have ever gone that far.
• Adaptation Expansion: The episode "Don't Do Anything Rash" opens with a flashback set during the reign of Emperor Argall, and thus showcases Thaedus when he was actually part of the Viltrum Empire, as he was a member of the war council, it also establishes that he and Thragg were something akin to Bash Brothers. By comparison the comic only has the single panel of Thaedus killing Argall.
• Anti-Hero: While he does fight to stop the Viltrumite's conquest, he's willing to go to some pretty nasty places to do so. Like wiping out almost all of them with a virus.
• Asskicking Leads to Leadership: As the only good Viltrumite leading the Coalition of Planets, he excels not only at guiding them in defying his former brethren and their tyranny, but also at kicking Viltrumite butt with his bare hands.
• At Least I Admit It: When Nolan calls him out for killing billions with the Scourge Virus, Thaedus points out that the Viltrumites have also killed billions of other people from other races.
• The Atoner: He seeks atonement for creating the monster that is the Viltrumite Empire under Thragg with the assassination of Argall and the Scourge Virus that made things worse by taking the fight to Viltrum with the Coalition and their allies, and end the Viltrumite threat once and for all.
• Authority Sounds Deep: Courtesy of the famously deep-voiced Peter Cullen.
• Bad Guys Do the Dirty Work: "Bad guy" is stretching it, but he's certainly "morally questionable" at best. Each and every one of his actions have brought the galaxy a fighting chance against a race of planet-conquering supermen, but he did this by assassinating the Emperor he swore loyalty to, inflicting a virus that wiped out most of their population, starting a galaxy-wide war to purge every last Viltrumite and eventually playing a part in destroying their home world and all that remained of their culture in an effort to dissuade the Viltrumites that there was anything left to fight for. All of this reduced the Viltrumites to only 37 members left alive by the end of season 4, and it's revealed that Thaedus was prepared to go even further with a modified version of the Scourge Virus that could wipe out species compatible with Viltrumites, specifically humans. By the end of the season, it's undoubtable that Thaedus has left his own race one step away from extinction, but he's only stopped from being a villain from his actions because of the sheer threat the Viltrumite way and every member's adherence to it make them to the wider galaxy.
• Became Their Own Antithesis: According to Thragg, as a general acting in service to the Viltrum Empire, Thaedus used to be ruthless even by their (Argall era) average, before he became a Defector from Decadence concerned with the welfare of the galaxy's other peoples above all else. Although in the present after his defection, it's hinted that Thaedus' past ruthlessness is still present underneath the surface, just redirected.
• Being Evil Sucks: More like being Morally Grey Sucks but he takes absolutely no pleasure in his questionable actions, and expresses genuine remorse to Nolan, and only authorizes the use of the second scourge virus if there’s no other options.
• Big Good: The one leading the Coalition of Planets against Viltrumites.
• Boomerang Bigot: Used the Scourge Virus to wipe out the vast majority of the Viltrumite population despite being a Viltruimite himself. Justified on the grounds that almost all Viltrumites are war-mongering, social darwinistic supermen whose goal are to conquer or wipe out the rest of the galaxy. That said, Thaedus' own words and Thragg's own questions to Nolan indicate that Thaedus would be willing to kill every remaining member of his own kind in the galaxy if he thought they had a chance of trying to rebuild the empire, even half-breeds like Mark and Oliver who show no interest in such, a concern that eats at the back of Nolan's mind.
• Broken Pedestal: He used to be held in high regard by Thragg and other Viltrumites before he assassinated Argall and is labeled as "The Betrayer". Thragg despised him because he refuses to have him executed by Argall's orders out of respect for Thaedus and it ends with the Emperor's assassination.
• Casting Gag:
  • It's not the first time Peter Cullen voiced a powerful and wise leader who fights for the freedom of all sentient beings against the evil forces that seek to subjugate them. Especially when it comes to fighting against his own race. Also, the tyrant he ended up assassinating is voiced by none other than Frank Welker, Megatron's VA. Not only that, he and Optimus are very brutal towards their enemies in combat. Coincidentally, Thaedus and Optimus Prime have a respective connection with two bearers of the name Scourge: the virus that reduced the Viltrumites to less than 50 remaining, and the leader of the Terrorcons from Transformers: Rise of the Beasts. Him getting beheaded by Thragg comes off as very ironic given Optimus Prime's habit of decapitating his opponents in the Transformers (Film Series). 
  • In the Brazilian dub, he's voiced by Carlos Campanile, whose roles include Superman in his animated series, fittingly for the Token Heroic Orc from what's essentially a race of evil Kryptonians. He's also known as the voice of Frieza, who like Thaedus, committed genocide against a Proud Warrior Race of Galactic conquerors (albeit for completely malicious reasons).
• The Chains of Commanding: Thaedus is easily one of the most altruistic and noble-minded characters in the series whose primary goal is to stop the spread of the ruthless, imperialistic Viltrum Empire. However, this nobility does not mean he is nice as the decisions he's made and the ruthless lengths he's gone to to ensure they are stopped demonstrate. Anything is on the table when the Empire is persistent on its endless campaign; some of his methods deeply haunt him even now as he holds tremendous guilt about inflicting his own people's steady path into extinction with the Scourge Virus just to stop them from killing any more worlds. In his posthumous message to Allen, he implores him to use the improved Scourge Virus to wipe out the remaining Viltrumites, even though there's a chance it could affect genetically similar species like humans too.
• Clark Kent Outfit: Underneath his robes, he has the same Heroic Build that all Viltrumites do. The Clothing Damage reveals it when Thaedus starts throwing hands with the Viltrumites, and later strips off his robes to take part of the assault on Viltrum.
• Combat Pragmatist: His modus operandi:
  • After failing to sway Emperor Argall and realizing he must go, he ambushes him at his room from behind while the latter's guard is down.
  • He created the Scourge Virus that would reduce billions of Viltrumites into less than 50 remaining, which severely limits them from overwhelming the galaxy with sheer numbers and they resort to subterfuge.
  • When Thragg and his forces attack Talescria, he immediately uses surprise attacks to catch Kregg and other Viltrumites off guard and successfully dispatch some of them.
  • After hearing that Thragg is calling all remaining Viltrumites back to Viltrum, he has the Coalition follow him to Viltrum where they will enact a plan of ending the threat of the Viltrumites once and for all: killing Thragg, and destroying Viltrum itself.
  • He admits to Nolan that he made a stronger variant of the Scourge Virus as an absolute last resort should the Coalition fail to take out the Viltrumites, but hid from him exactly how it was stronger — the virus attacks not only Viltrumites, but compatible species with them, like humans, meaning Thaedus was, if pushed into a corner, willing to re-enact the near-genocide he inflicted on his people on completely innocent species as collateral in the aim of wiping out any hope for the Viltrumite Empire to be rebuilt. He furthermore left a posthumous message to Allen instructing him to release said Virus upon his death, even acknowledging in the same message that it'd likely decimate Earth and Mark specifically, but he just couldn't take the chance of even one Viltrumite surviving.
• The Comically Serious: He's much more composed and serious than the casual and laidback Allen, making for some humorous moments when they interact.
• Corrupted Character Copy: Of Peter Cullen's most famous role, Optimus Prime. Like the latter, Thaedus is The Leader of an alliance dedicated to protecting other civilizations from an evil empire conposed of his own species. But while the Autobots Optimus leads includes several other Cybertronians who share his ideals, Thaedus was the Token Heroic Orc of the Viltrumites until Mark came along. Additionally, while the Autobot-Decepticon war is/was brutal, it usually only affected their species until they reached Earth. By contrast, the Viltrumites have been actively fighting and exterminating other civilizations well before Thaedus turned against them, amassing an immeasurable body count. Thirdly, while the Decepticons usually tend to disband if/when Megatron dies due to the latter being the only one holding them together by fear and force of will, the Viltrumites responded to Argall's death by crowning Thragg Grand Regent and doubling down on their worst traits. All of this profoundly tainted Thaedus' view of his own people until he saw them as Always Chaotic Evil and made plans to enact a Final Solution against them because as far as he can tell, they will never give up their ambitions to conquer the universe even in the face of extinction. This, in turn, deconstructs Optimus' famous line from The Transformers: The Movie, "Megatron must be stopped, no matter the cost" - specifically, in regards to what that cost is. Optimus utters the line just before going into battle against all of the remaining Decepticons, framing his remark as a potential Heroic Sacrifice where he will do whatever it takes to defeat Megatron even if it gets him killed as well. Thaedus, however, uses the remark in a video Allen was supposed to receive only if Thaedus was killed, in which case Allen is to use the improved version of the Scourge Virus to wipe out all remaining Viltrumites, even though there's a high risk of the virus affecting genetically similar species like humans. Whatever flaws Optimus has, sacrificing another species to defeat the Decepticons has never been one of them, and this decision fully emphasizes that Thaedus had become just as monstrous as the rest of the Viltrumites, with his only difference being who his dark actions were aimed toward.
• Create Your Own Villain: Downplayed as Thragg is already antagonistic, but he used to respect Thaedus and refused to execute him when Argall suggests it. Thaedus killing the Emperor enrages Thragg into holding a lifelong grudge against him and leading the Viltrumites into doubling down on their ways. Thaedus ends up dying by Thragg's hands after Viltrum is destroyed by him, Mark and Nolan.
• Death Seeker: He admits that, even if he isn't killed as punishment for unleashing the Scourge Virus on his people, he'll likely just kill himself one day out of guilt for wiping out most of his race. He inadvertently gets his wish from Thragg who rips his head off.
• Defector from Decadence: After Allen fully recovers from his injuries, Thaedus reveals himself to be not only a Viltrumite, but the first and only one of his kind to have openly rebelled against the Viltrum Empire until he learns about Mark Grayson.
• Didn't Think This Through: Threefold. Thaedus killing Argall and later unleashing the Scourge Virus in hopes of giving the Viltrumites a Humble Pie to reform themselves ends up causing them to double down on their Might Makes Right mindset and to continue conquering the universe. Later on, he expects the Viltrumites to surrender after he, Nolan and Mark destroyed Viltrum only for an enraged Thragg to tear his head off.
• Dies Wide Open: His decapitated head has this when Thragg tears it off in a fit of rage before brutally squashing it apart, horrifying the Coalition.
• Elderly Immortal: Considering that the Viltrumites can live for thousands of years with minimal aging, Thaedus stands out for looking like an actual old man. He is actually older than the Viltrumite Great Purge, and by Nolan's young adulthood was Viltrum's most notorious traitor.
• Exact Words: Thaedus makes it clear that he wants the Viltrum Empire to be "a mercifully forgotten memory". It's implied that he means all Viltrumites need to die, including Nolan, Mark, Oliver, and himself.
• Failure Hero: Downplayed, as Thaedus is the biggest reason the galaxy has had any chance of meaningfully standing up to the Viltrumites. However, he has a bad track record of horribly misjudging the effects of his actions on his people at the worst possible moments. In trying to find the masterstroke that will break the Viltrum Empire for good, Thaedus repeatedly ends up inadvertently cultivating the stubborn Viltrumites' will to triumph. Even as the Empire's tactical situation degrades and its numbers dwindle, the gains aren't as good as they could be because the remaining Viltrumites get even more disproportionally dangerous. Thus, although his efforts cost the Viltrumites almost everything, including Viltrum itself, nothing truly goes according to Thaedus' plans and he dies without being able to see the Empire's defeat.
• Fake Facial Hair: Subverted. Thaedus is the leader of the "Coalition Of Planets" and is secretly a Viltrumite who had defected from the Empire because of its brutal, warrior culture. Thaedus hid his Viltrumite identity by growing a beard, and when he reveals his identity to Allen, he rips it off as if it were a fake beard. When Nolan doubts Thaedus' identity on their first meeting, he refuses to perform it again just to sate his doubts as it is understandably painful to rip off your own grown beard. 
• Famed in Story: According to Thragg, Thaedus was the strongest and most ruthless among a company of Viltrumites, and they fought together as Bash Brothers at Capella Minor.
• Fatal Flaw: Throughout his life, he underestimates his people's stubbornness. He believed that killing Argall, unleashing the Scourge Virus, and destroying Viltrum would respectively shatter the Viltrumites' arrogance. The last two acts only galvanized them into doubling down instead, and the last one ultimately costs him his head by Thragg's hands.
• Five-Second Foreshadowing: When he learns there are less than 50 Viltrumites left, Allen and Telia both note he seems somber, with Allen noting he'd expect Thaedus to be happier, and Telia brushing it off at his shock that his own species is near extinct. The following scene has him reveal he's the one who engineered the scourge. He never knew how effective it had been, and is himself horrified by what he's accomplished, even if he feels it was necessary.
• Frontline General: Being a Viltrumite who's leader of the Coalition of Planets, it is to be expected of Thaedus to throw hands with his former brethren and take part of the counterattack on Viltrum where he, Mark and Nolan destroy the planet's core with help of Space Racer's blast.
• Genocide from the Inside: A rare heroic example. Season 4 reveals that he was the one who created the Scourge Virus and unleashed it upon Viltrum, which ended up killing billions upon billions of Viltrumites, his own kind, and thus nearly bringing his own race to total extinction.
• Godzilla Threshold: He's the creator of one. In one last desperate attempt to stop the Viltrum Empire's threat to the galaxy when assassination and standard rebellion failed, he unleashed the Scourge Virus, which was so deadly that it reduced their population to less than 50. And he is in the possession of an even deadlier variant in the event that the Viltrumites become unstoppable. It's also made clear that he absolutely hates himself for having unleashed it in the first place, even if it was to stop the Empire's conquest.
• Good Cannot Comprehend Evil: He believes that Viltrumites are capable of thinking for themselves and have a capacity for change to be good people, and by taking out Emperor Argall, they would be free from his toxic influence that defined The Empire. Unfortunately, he underestimates how entrenched the Viltrumites are in their way of life and they double down on it when they're all too willing to carry out the Great Purge under Thragg's first decree as Grand Regent rather than try to defy it. Understandably, he doesn't believe Mark Grayson to be a good Viltrumite until Allen testifies for him and the Coalition leader eventually meets Mark himself, and that he is vindicated by Nolan's Heel–Face Turn. However, he still doesn't remotely consider the possibility of the other Viltrumites changing for the better due to them doubling down on Argall's ideology when they had the chance. This eventually plays a factor into his final order to Allen from beyond the grave, which is to use the improved Scourge Virus to kill all Viltrumites and any species that shares enough genetic similarities to them, like humanity, assuming his death would mean that the Viltrumites are winning against them.
• Good Is Not Nice: While he's dedicated to stopping the Viltrumites, he's very focused on the big picture and able to shrug away the casualties of war. While claiming to still feel the loss, after the attack on Talescria devastates the civilian population of the capital his first reaction is to tell Allen that it's ultimately a minor setback that just proves how desperate the Viltrumites are. Allen calls him out on treating the devastation as just a hard numbers game, but Thaedus is resolute that they must consider the greater conflict as a whole rather than the moment. This is emphasized by his final order to Allen to release an even more powerful Scourge Virus that targets innocent species as well just for being genetically compatible with Viltrumites, proving just how much he is willing to sacrifice if it means that the Viltrumites are gone for good.
• Good Is Not Soft: While Thaedus despises how vicious Viltrum society has become, when they launch an attack on the Coalition homeworld, the elder Viltrumite pulls no punches against them and proves to be a downright vicious combatant himself, killing a few and forcing back elites such as Kregg and Anissa who find out the hard way.
• Hates Their Parent: Discussed. Thaedus buys Allen's story of Mark turning against Nolan because while Viltrumites are not known to fight each other, a son can certainly hate his father enough to defy him.
• He Who Fights Monsters: Spent his entire life being so disgusted at the Viltrumite Empire's wanton destruction across the galaxy that he would do anything to ensure their extinction, to the point of making the Scourge Virus even more lethal by having it affect innocent species just to prevent them from breeding back their numbers. For all of his justified hatred of Viltrumite ideology of genocide, he ultimately becomes equally genocidal against them.
• Hypocrite: Despite being the first Viltrumite to turn against the Empire for ethical reasons, he can't comprehend any other Viltrumite joining his side, even allies like Nolan, Mark, and Oliver. Justified as until Mark came along, he only saw Viltrumites double down on their echo chamber rather than face the harsh facts of their problematic culture for a millennia. 
• I Did What I Had to Do: He views the destruction of the Viltrumites as a brutal necessity to stop their conquest, even if it tears at him.
• Internal Reformist: He attempts to be this at first when trying to convince Argall, Thragg and Kregg and their fellow Viltrumite councilors to consider a better and more pragmatic stance with the vassal world's rebellion. He drops this after seeing there's no changing their minds, resorting to assassinating the Emperor and later unleashing the Scourge Virus. 
• Irony: The series adds a scene which shows that his final straw was a proposed culling of a slave race over repeated terrorist attacks. So he killed Argall, which led Thragg to take power. Between Thragg's purge, the Scourge Virus, and the destruction of Viltrum, Thaedus' actions almost destroy the entire Viltrumite race.
• Jerkass Has a Point: Downplayed on the jerkass part but when Nolan angrily confronts him about the Scourge Virus that "killed billions", Thaedus points out that the Viltrumites themselves killed billions before he released the virus. There's also the fact that with how powerful the Viltrumites are, and how numerous they used to be, defeating them in a more conventional and merciful way simply wasn't an option.
• Killed Off for Real: Thragg brutally decapitates Thaedus just as it seemed like they dealt a decisive blow to the Viltrum Empire's morale by destroying their homeworld, being the first casualty in a vicious Curb-Stomp Battle that follows from the aggrieved leader.
• The Kingslayer: He was the one responsible for the death of Emperor Argall after realizing that he would not turn from their destructive path.
• The Leader: The man in charge of the Coalition and Allen's boss.
• Light Is Good: He wears white robes and has fully grown white beard as the leader of the Coalition opposing the tyranny of the Viltrumite Empire.
• Manly Facial Hair: One of his most distinctive attributes is his big bushy beard, and he's the leader of a heroic rebellion against the Viltrumite Empire. He later rips his beard off, leaving only a mustache, revealing himself as a Viltrumite to Allen. In the flashback, he has his mustache during his meeting with Emperor Argall and Thragg.
• Mirror Character: To Cecil, if Cecil were responsible for leading galaxy wide organization with thousands of solar systems to protect. Both of them are aged men that for all effects and purposes should count as the Big Good of the story, but are forced to take some less than savory actions to save others, and their tunnel vision more than often causes them to make huge mistakes in the long run.
• Missing Steps Plan: He assumes that with his plan of assassinating Argall, the Viltrumites would be able to change their ways by themselves. However, he doesn’t realize that Thragg will take command of the Viltrumite Empire as the Grand Regent in the Emperor's place and his first order of business will be to have everyone fight each other to the death in the Great Purge.
• Muscles Are Meaningful: Thaedus is jacked under his robes and his performance in "You Look Horrible" shows they aren't just for show. He takes on Kregg, Lucan, and Anissa individually and overpowers them easily. He also assists in lifting the wrecked remains of Thragg's flagship about to fall into the city and sending it to space, and is strong enough to smash through the core of Viltrum with Nolan and Mark.
• Nice Job Breaking It, Hero!:
  • As Season 4 reveals, it was Thaedus' actions that unfortunately shaped much of the modern Viltrumite Empire's policy for the worst despite trying to do the opposite. His assassination of Emperor Argall ages ago to stop his tyranny ironically led to the Great Purge that tore at the Viltrumites and made them the bloodthirsty conquerors they are known for being. Then, in an attempt to atone for the monsters he created, Thaedus created the Scourge Virus to commit a genocide against his people, bringing their billions strong number down to less than fifty pure-bloods left — though he had not known the consequences of this action for centuries due to how well-hidden this blow was by Thragg, which led to their current policy of seeking out other worlds to bolster their kind once more which directly led to the events that kickstarted the series with Viltrumites like Nolan seeking out places like Earth to serve as breeding sites.
  • Near the end of the war, Thaedus' plan to destroy the planet Viltrum in order to force the Empire to surrender has even worse consequences. Not only does he die minutes after it happens, but it also leads to Thragg taking all the remaining 37 Viltrumites left to Earth so they can procreate with humans, essentially pushing them to a position where the Viltrumites can rebuild their forces to threaten the universe once again in the future.
• Non-Action Guy: Despite being an exile from a race of Flying Bricks, he's content to be a political leader, strategist... and bioweapon scientist. However, this is a conscious choice of his, as at the end of the day Thaedus is still a Viltrumite with all that entails and will rise to battle if deemed absolutely necessary when all cards in the deck must be used. Thus, when the Viltrumites directly invade Talescria, Thaedus shows no hesitation in joining the fray himself and quickly shows his long decades on the sidelines haven't dulled his edge, pretty handily thrashing even experienced Viltrumite higher-ups like Anissa and Krieg.
• Noodle Incident: His experience in the Leigh Quadrant, that Thragg mentions to Emperor Argall, causes him to have a Heel Realization and reject the cruel ways of the Viltrumite Empire.
• No Place for Me There: He's an ancient Viltrumite who wiped out most of Viltrum to stop their evil deeds and leads the Coalition against the Empire. He's consumed by guilt for what he's done and notes he'll likely kill himself once the war is over. In Thaedus's view, the Viltrumites must go extinct for the Galaxy to know peace and he views his own death a necessary final step.
• Not So Above It All:
  • Despite being very serious and level-headed, when Nolan confronts him about his identity as a Viltrumite, Thaedus asks that he not have him perform "the ritual" of ripping off his beard to prove his claim, which unsurprisingly hurts like hell to do.
  • He's abandoned his people's arrogance and obsession with strength, but in his fight with Krieg over Viltrum, after breaking the latter's arm, he outright insults him by saying he was "always weak".
• Not So Different: As the final scene of Season 4 reveals, Thaedus hasn't completely shed his Viltrumite perspective of the galaxy - still willing to wipe out a dangerous species the moment he gets a chance, no matter how many innocents have to suffer in the process. It's just that the species in question is his own.
• Off with His Head!: Thragg decapitates him with his bare hands after the destruction of Viltrum, and then crushes his head to the horror of everyone present.
• The Older Immortal: He's heavily implied to be a survivor of the Viltrumite Great Purge, which makes him even older than Nolan. Season 4 reveals because he was the cause of the Great Purge when he killed Emperor Argall and sent the original Viltrum Empire in a free-fall spiral in hopes of breaking it free from its tyrannical ways, making Thaedus possibly the oldest living Viltrumite present until his death at the hands of Thragg.
• Old Soldier: As a Viltrumite, his advanced age doesn't slow him down at all in battle, which Oliver is surprised to see as he takes part in the battle. When he gets into the action, he's able to easily beat the brakes off Kregg, swat Lucan and Anissa aside, and dispose of an unnamed Viltrumite with a Neck Snap.
• Only Sane Man: Back during Argall's rule when Thaedus was still loyal to the Viltrumite cause, he was the only Viltrumite at the time who openly questioned their hypocritical nature of their rule over the universe and how selective their Might Makes Right philosophy truly was, even when Thaedus offers to share the viewpoint that the resistance towards their rule proves their creed of strength even in spite of overwhelming odds. It was his rationale, especially when disregarded due to how deeply racist the Viltrum Empire actually was, that compelled him to kill Argall and create the Scourge Virus as attempts at discretion were disregarded for simple extermination of anyone who dared rise against them.
• Open Secret: His identity as the Betrayer was long known among Thragg's inner circle, but due to Talescria being so heavily fortified and the heart of the Coalition on top of being the one who developed the Scourge Virus against his own people made them very wary of trying to claim vengeance for the longest time until they finally have their opportunity to attack thanks to The Mole lowering the planet's defenses. Even his status as a Viltrumite, while kept from the public, was known within all members of the Coalition's council as they refer to him as a "Viltrumite In Name Only", naming him the one example they will tolerate as a "Good" Viltrumite.
• Paper-Thin Disguise: He hides his true identity as a Viltrumite by... simply growing his long bushy beard that hides his mustache. He rips it off once in front of Allen with his mustache remaining. After growing it back again, he refuses to remove it due to how painful it is when Nolan is skeptical of him. 
• Parental Substitute: He has a very fatherly relationship with Allen, who clearly looks up to him and is eager to please. He looks after Allen who was severely injured and healed that made him a lot stronger.
• Pet the Dog: Ruthless he may be, but the first thing he does in his Video Will where he orders the extermination of the Viltrumites is assure Allen that he has earned the position of Head of the Coalition and that he knows he’ll do good.
• Please Kill Me If It Satisfies You: When Nolan grabs him by the neck and pins him to the wall after learning that he created and unleashed the Scourge Virus, he offers no resistance and tells Nolan to go ahead and kill him if he feels he deserves to die for it, and that he wouldn't blame him for feeling that way.
• Pragmatic Villainy: Played with. Thaedus did have moral objections to the desire of the imperial circle to cull or exterminate the Relonians, but knew trying to appeal to their morality would not work. So he instead tried to convince them of the benefits of restraint and the long haul...but this was equally ineffective.
• Reasonable Authority Figure: He leads the Coalition of Planets this way as he is willing to hear out Allen's testimony about Mark Grayson and to work with him, Oliver and Nolan, who is also a Defector from Decadence, in fighting against Thragg and his remaining Viltrumites.
• Red Baron: As Thaedus, most Viltrumites have never heard of him. But they all know him as "The Betrayer," for his assassination of Emperor Argall.
• Reformed, but Not Tamed: While he has turned his back on his people's genocidal ways towards other species, he instead has turned his attention towards the genocide of them. His insistence on thinking of the long game against the Empire suggests that while he may be on the side of good now, the Viltrumite in him is still there, just being redirected. It then gets Subverted when the Season 4 finale reveals that his newly improved iteration of the Scourge Virus is capable of killing all races genetically compatible with Viltrumites, which would result in the extinction of humanity. He may not be committing genocide in the name of imperialism and pure evil, but it's still a line he's willing to cross for his goals of stopping the Empire.
• Rousing Speech: He gives one to the Coalition of Planets forces at the onset of the Viltrumite War.
  Thaedus: It is time for war! The Coalition of Planets have never been more unified, more determined, more ready. And Viltrum has never been weaker. Fifty Viltrumites hide behind their conquered armies, while millions of us rise together against them! We will end their cruelty! We will end their atrocities! We will end their tyranny! They believe that their strength is insurmountable, but they are wrong. Together, we have discovered their weaknesses, and we will use them to break their hold on the galaxy. Decades of planning, of strategy, of patience and unity and hope, have led us to this moment. There will be loss, and there will be sacrifice. But it will be less than the suffering Viltrum brings upon us every single moment they exist. Remember always: if we remain unified against their empire of pain, we will prevail! Let the war begin.
• Sleeves Are for Wimps: When leading the counterattack at Viltrum where Thragg and the remaining Viltrumites gather there, he wears a second outfit similar to his previous one. This time, he shows off his bare arms.
• Slowly Slipping Into Evil: An arguably nuanced take on this, and he doesn't exactly end up as "evil" by the end of it, though certainly extremely "morally gray". Thaedus has done more to wipe out his own species and culture than any single being in the galaxy, using methods that would make him a monster had they been used against any race that wasn't a conquering, supremacist empire, but each step along that road has been a gradual escalation in his attempts to deter their own self-destructive ideology. He assassinated Argall in hopes that without him, more rational Viltrumites might steer the Empire onto a different course; only for Thragg to instead assume command and enact The Purge to weed out any "weakness" in their species. With their race's numbers making them far too powerful to fight head-on (each individual is arguably a planet-destroyer), Thaedus then unleashed the Scourge Virus to try and weaken the empire and allow other races a chance to fight them off, only for Thragg to hide how devastating a blow the virus has inflicted upon them, leaving Thaedus unaware of how close his race was to being wiped out as he sought other methods to fight them. When he learned about it, and Thragg's solution of dealing with the population problem, it convinced him to have another, stronger version of the Virus made that could finish the job, even if it meant making it capable of affecting compatible species like humans too, and Thragg points out that his desire to avoid another empire rising one day meant he'd eventually turn on even heroic Viltrumites like Mark and Oliver. By the end of season 4, Thaedus is undoubtably the main reason why the Coalition has the Viltrumites on the back foot, but he's far from being a saint in his methods — something that he's deeply aware and ashamed of, even as he doubles down on them being "necessary".
• Strong and Skilled: He's incredibly strong, being a Viltrumite. And he's a refined, trained warrior who's old by Viltrumite standards.
• Surprisingly Sudden Death: He's unceremoniously decapitated by Thragg after destroying Viltrum with Mark and Nolan, emphasising the former's sheer power that had been held back during the fight by his reluctance to hurt "true members" of the Viltrumite race.
• These Hands Have Killed: After he reveals the truth of his crimes to Nolan about creating the Scourge Virus, he admits that while necessary to stop the Viltrum Empire's conquest that there's not a moment as he remains awake that doesn't haunt him with guilt over his actions to the point he earnestly is prepared to die by Nolan's hands as penance for it and, even when spared, one day desires to kill himself if no punishment comes for him as to atone for them.
• This Cannot Be!: A rare heroic one; he's shocked to be told of Mark and Omni-Man's fight as it's the first time Viltrumites have fought each other since the Great Purge. This implies some things about what made him a Defector from Decadence.
  Thaedus: Viltrumite against Viltrumite? That has not happened since the Great Purge...
• Token Good Teammate: Before his defection, he tries to reason with Emperor Argall in a meeting about dealing with a rebellious world and he used to have a high standing in the Viltrumite Empire.
• Token Heroic Orc: Was the very first Viltrumite in their entire history to go against their ethics of Might Makes Right created by Emperor Argall, going as far as to assassinate their beloved emperor in hopes of destroying his ideology's hold over their civilization. Even centuries later, he remains the only Viltrumite who is wholly altruistic in his beliefs from the get go whereas Mark and Nolan have their own justifiable, but largely personal reasons to fight the Empire, something that is proven conditional by alternate timelines where different circumstances have made them as fanatical as any other Viltrumite. Though the "heroic" part is ultimately downplayed when we learn just how far he's willing to go.
• Underestimating Badassery: Thaedus has a terrible habit of inapproriately gauging the lengths the Viltrum Empire will go to preserve its ideology by any means necessary, and just how hard it is to actually break them from it as even the very real threat of genocide will not deter them from being dogmatic fascists. It is also what gets him killed in the end as destroying Viltrum didn't demoralize them, just as every other attempt to break them prior had failed, but radicalized them further as Thragg violently kills Thaedus rather than dare surrender to him.
• The Unfettered: Downplayed. Although Thaedus shows remorse for the genocide he committed through the Scourge Virus, when Nolan addresses the fact that surviving Viltrumites wouldn't need to die after Thragg is killed, Thaedus say that he won't risk any of them rebuilding the Empire and insists that their species must be made extinct, even implying that Mark and Oliver would also be included on his hit list due to their Viltrumite lineage. Thragg even points this out to Nolan, who can only deflect by saying he won't let it come to that if the remaining Viltrumites just surrender peacefully and talk terms.
• Unwitting Instigator of Doom: Assassinating Argall and unleashing the Scourge Virus is what drove the Viltrumites to become even more dangerous than they were before.
• Video Wills: He left one to Allen in the event of his death, which includes his final order while granting him access to the improved Scourge Virus.
• Walking Spoiler: The majority of his screentime takes place after The Reveal that he is a Viltrumite, specifically the first Viltrumite to ever defect from the Empire and the creator of the Scourge Virus.
• Well-Intentioned Extremist: He committed genocide on his own people to stop their genocide on so many others, and sends a message to convince Allen to release the upgraded Scourge Virus onto Earth, knowing that it would also kill innocents like humans, just to stop the Viltrumites from being able to breed and regain their army. There are likewise hints he views any Viltrumite as a threat, even Mark and Oliver despite their different origins and upbringing.
• Where I Was Born and Razed: A rare sympathetic example. Thaedus committed genocide against his own people with the Scourge Virus, reducing them from a planet of billions down to less than fifty. Given that Viltrumites are an entire species of planet-conquering Space Nazis who not only don't listen to reason, but double down even after they've been proven thoroughly wrong, this is much less evil of him than it would be for any other people and planet.
• The Worf Effect: He's shown to be a competent Viltrumite warrior, going head to head with Kregg, Lucan and Anissa, but gets put on the receiving end of this by Thragg who effortlessly tears his head off before Thaedus can even react, shocking everyone witnessing his demise.

Allen the Alien

Voiced By: Seth Rogen (series), James Adomian (Invincible VS)

Initially believed by Mark to be some recurring threat he is sent to fight, Allen is an evaluation officer for the Coalition of Planets whose job is to assess the security of member worlds.

• Adaptational Nice Guy: In the comics, it's his independent decision to unleash Thaedus' improved Scourge Virus on the remaining Viltrumites, even knowing it will target hybrids like Mark and Oliver and may target humans as well. In the show, Thaedus posthumously issues an order to him to unleash the virus, clearly banking on Allen being too loyal to him to refuse.
• Adaptation Distillation: In the comics, Allen was actually an annual threat for fifteen years, coming to Earth every year only to be repeatedly defeated and pushed back by Nolan, who doesn't exchange a single word with him the entire time. Here, this is simply alluded to as an incident of Allen fighting Nolan three years ago.
• Adaptive Ability: Normally, he's capable of taking on a young and inexperienced Viltrumite, but it turns out this is about his limit when it comes to their race as he is brutally creamed by their actual warriors on his first outing and three adult Viltrumites ganging up on him leave him a mutilated husk barely clinging to life. However, it turns out that his body has the ability to perfectly recover and adapt to severe injuries, with him growing significantly larger and exponentially stronger from his near-death experience, such that he can now fight back against some of Viltrum's best warriors evenly.
• An Alien Named "Bob": A space superhero tasked with assessing member worlds by The Alliance - and goes by the rather mundane name Allen. Apparently it's his race's thing, as the ambassador who led his people into the Coalition is named Marvin.
• Aliens Love Human Food: In the Season 2 Teaser, Allen eats a burger from Burger Mart and remarks on the great taste of the burger he had eaten. Subverted with pickles inside the burger, as Allen suggests to Invincible that it tastes disgusting to eat.
• All-Loving Hero: He has a remarkable ability to show kindness and understanding even to people actively or recently trying to kill him.
• All Planets Are Earth-Like: And have similar-sounding names apparently. With the English alphabet. Allen came to Earth because "Urath" asked for an evaluation of their defenses, confusing the two planets. Not helped by the fact that Urath has very similarly shaped continents to Earth, if the tablet was anything to go by.
• Alternative Calendar: Upon learning that Invincible season 2 is set on being released in the year, late 2023, Allen becomes excited that of its release date, but he is unsure of how long it will take because different alien planets keep track of time by using different calendars.
• Attack Its Weak Point: While it's not enough to take him out of a fight, comparatively weaker opponents like Invincible or a bunch of Mooks are able to hurt him by hitting him in the eye, to the point that it becomes a Running Gag during his team-up with Omni-Man.
• Back for the Finale: Makes a return to Earth in the finale of Season 1, a bit too late with the news that the Earth has a Viltrumite on it and then has to be brought up to speed on what has happened after he left Earth.
• Big Brother Instinct: Allen may not be Zoe’s real brother, but he sure acts like one—bonding with her over gaming and repeatedly throwing himself into danger to keep Tech Jacket safe during the chaos of the Viltrumite War.
• Big Fish in a Bigger Ocean: Tragically. By the standards of most people (including his own), his power is utterly immense and he's a mighty superhero... but his enhancements aren't enough to match the powers of the Viltrumites, who are on an entirely different level. He lost his first fight with one, and when faced with three, he ends up beaten to near-death. Subverted after returning from near-death with a power boost; Thaedus speculates that Allen now can match and perhaps even beat a Viltrumite, and is proven right when Allen fights Anissa and barely feels any pain from her hits. While he can't consistently win against Viltrumites from then on, especially when he's outnumbered, he's now actually capable of defeating a Viltrumite in single combat.
• Big Good: He takes over leadership of the Coalition of Planets after Thaedus' death.
• Came Back Strong: After almost getting beaten to death by three Viltrumites and then having his life-support cut off while in the hospital by Thaedus, Allen not only survives but grows greatly in strength and size from the experience. Previously unable to defeat even a single Viltrumite, now he can hold his own amongst their best.
• The Cavalry Arrives Late: By the time he comes back to reveal that Earth is off-limits due to there being a Viltrumite at the end of Season 1, he's pretty much missed out on the whole ordeal regarding Omni-Man.
• Combo Platter Powers: Not only does he have Flying Brick powers but also has telepathy. Allowing him to be a match against Invincible but also talk with him telepathically while in outerspace.
• Defeat Means Friendship: Averted. Rather than finding out the misunderstanding at the end of their fight, he and Mark talk things out during a "timeout". Which allows them to settle the conflict early and peacefully, due a misunderstanding at Allen's part.
• Didn't Think This Through: It never occurred to him to check with the Earth's populace to see if he was at the right planet.
• Endangered Species: The Viltrumites conquered his people years ago. When they resisted, the Viltrumites nearly wiped out his entire species. Those few who remained had to resort to breeding camps just to sustain their numbers. Allen is the result of an experiment to make one child from such a breeding camp superpowered so that they could fight back against the invaders.
• Explain, Explain... Oh, Crap!: After getting into a brief fight with Mark, he eventually learns that he's gone to the wrong planet. He was supposed to be inspecting Urath and leaves since he might be fired over this blunder.
• Expy: A Super-Soldier who was granted powers by artificial means, who is also member of an alien species that was pushed to the brink of extinction, and is good friends with The Hero? Yep, Allen is the the show's version of Beta Ray Bill.
• Eye Scream: Part of the very brutal beatdown he receives at hands of three Viltrumites. One of Thula's punches ends up dislocating his eye from his head, though it remains attached by its optical nerves. By the time we see poor Allen again, his face is covered in bandages.
• Failed a Spot Check: Mistaking Earth for Urath is one thing, but he also missed that the guy he fought last time he came by, making sure the planet could defend itself from Viltrumites, was a Viltrumite.
• Fire-Forged Friends: They knew each other previously, but him and Nolan become genuine friends whilst being detained in a Viltrumite prison despite the latter's assertions they aren't early on. It's to the point their newfound friendship is strong enough to convert Nolan from being a neutral party who defected from the Empire and was awaiting his execution to an enemy of his people proper when a Viltrumite was actively trying to kill Allen in front of him.
• Flawed Prototype: He's far more powerful than any other member of his race… but Allen was intended to be able to defeat Viltrumites, so he was considered a failure when his base level of strength was considered "only" equal to a young Viltrumite (a species that grows Stronger with Age). However, this flips into Super Prototype when Allen manages to survive a horrific beating by a team of three Viltrumites and his body adapts to overcome what he couldn’t defeat before. The scientists that created him simply didn't fully understand how his powers worked yet.
• Flying Brick: He has a similar powerset to most Viltrumites: Super strength, durability, speed, endurance, reflexes, and agility. Although he has Telepathy added to all that. Unfortunately, at his initial base power level, he's not quite on the same level of Flying Brick as even the weakest of Viltrumites. After a horrific demonstration of this, Thaedus takes a gamble with Allen's life to make him come back strong, able to match against the elite of the Viltrumites in Super-Strength and Super-Toughness.
• Friend to All Children: He gets along very well with Oliver and Zoe, with whom he does some playful sparring with and plays video games with respectively.
• Genocide Backfire: He's the byproduct of the Unopans refusing to lose hope after their homeworld was lost to Viltrumite occupation, being a Super-Soldier created with the specific purpose of challenging their extreme strength.
• Gentle Giant: Beneath his big and burly appearance, he's a sensitive soul who really just wants to do what's right and help people.
• Good All Along: The mysterious alien cyclopean Flying Brick that attacked Nolan for no reason is, in fact, a civil and friendly security inspector for The Alliance and a freedom fighter against the Viltrum Empire.
• Go Out with a Smile: He's shown smiling during his beatdown at the hands of three Viltrumites, knowing that he's at least saved the innocents at the diner and his girlfriend Telia from being targeted by them. Thankfully it is a near thing, he manages to just barely survive.
• Heroic Sacrifice: When some Viltrumites find him and interrogate him about his knowledge about what happened on Earth, Allen realizes that if he drags it further, they might hurt and kill innocent people near them in space, including his lover Telia, so he eggs them on to focus their rage on him and him alone, beating him mercilessly. Given how Telia is by his side at a hospital, it worked.
• Hero of Another Story: Mainly in Season 1. A member of the Coalition of Planets, his job is to assess how secure certain worlds are. He has his own adventures to worry about which we don't get to see much of. At the end of his introduction he goes back to the Coalition and seemingly begins looking for Urath. This changes when he returns in the finale, where it's revealed he and the Coalition are seeking out allies to wage war against the Viltrum Empire, meaning they are far more important to the show's overarching plot than his debut made it seem.
• Huge Guy, Tiny Girl: Forms this dynamic with Tech Jacket in Season 4 since she is a petite, teenage human while Allen is a tall, hulking alien.
• Humanoid Alien: A burly and top heavy cyclops alien with only three digits per hand and two toes for his feet.
• Late to the Realization: Granted it was most definitely because he was gone and away from Earth, but when he returns to Earth with the news of there being a Viltrumite, he's missed out on everything that has happened since he left and has to be brought back up to speed by Mark.
• Mellow Fellow: For a gigantic alien Super-Soldier, he's extremely chill, with a lot of the inherent comedy of his character coming from his nonchalant attitude in bizarre situations. He's not immune to the standard Trauma Conga Line of being a superhero in this story, but he handles it a lot better than most.
• Muscles Are Meaningful: After recovering from being beaten to near-death by the Viltrumites, his body is noticeably bulkier than it was before. In fact one of the first things he does after waking up (and accidentally breaking his recovery machine) is admire his new biceps. Correspondingly, he's now much stronger than he was previously.
• Nice Guy: After he and Mark talk things out, the two get along pretty well. When he comes back in the last part of the finale, he is willing to listen to Mark's story and tries his best to be understanding of his plights, even trying to lighten up the mood by revealing his own baggage. He also defends Mark vigorously to the Coalition's leadership when they question his trustworthiness and is a loving, if dorky, boyfriend to Telia. His sheer friendliness manages to gnaw away at Nolan's walls while they are both in detention, allowing them to become genuine friends and complete Nolan's Heel–Face Turn into an enemy of the Viltrum Empire because of how close they become in the interim.
• Once Is Not Enough: Positive version. The Viltrumites who beat him up "only" beat him until he's a mangled body, but they do not Make Sure He's Dead. Thanks to that, Allen recovers stronger than ever and can now match them in combat.
• Poor Communication Kills: Zigzagged, as Mark is given no explanation of who Allen is or why he's coming to Earth. Doing so actually allows him to honestly tell the alien Mark doesn't know what's going on, using his "time out" to get an explanation and clear up the confusion. This ends up being fully subverted in the Season 1 finale - Allen never communicating with Omni-Man before and learning he had the wrong planet sooner meant he didn't yet learn that Earth had a Viltrumite on it, which he would've felt obligated to warn Earth's defender about. Mark even lampshades this, pointing out that if Allen had told him about the threat, Mark would've just reported it to his dad, and then Omni-Man probably would've gone on his rampage sooner.
• Reassigned to Antarctica: After it became clear that his powers weren't enough to defeat Viltrumites, he was deemed a failure and shifted away from the frontlines into the position of testing planets' defenses. He's hinted to have some insecurity about this.
• Superheroes in Space: He's basically the Coalition's very own superhero.
• Super-Soldier: He was created as part of a program to create superpowered warriors to fight against the Viltrumites. Unfortunately, his power level turned out to be far below theirs and he was deemed a failure.
• Super-Toughness: While Allen is unable to stand up to even a single Viltrumite, he is one of the few people in the universe who lived to tell about it. Even after three Viltrumites beat Allen so hard his eyeball popped out of his socket and they tore out his entrails, he survives long enough to be put onto a hospital bed (mind you, he was also in space). After recovering from that battle, Allen's durability improves further. He takes an uppercut from Anissa without any real injury, remarking that should have hurt a lot more; mind you that earlier in the episode, the same uppercut shattered Mark's mask lenses and nearly knocked him out cold.
• Telepathy: He has an implant in his skull that allows him "speak" to other people mentally even when speech is otherwise prevented by the vacuum of space. It initially only works to and from Allen, so others trying to communicate with each other in vacuum have to relay messages through him and it's really annoying. He mentions an update is coming and later gets it, allowing anyone around him to brain-talk with each other seamlessly.
• Top-Heavy Guy: Downplayed. Allen does have some big strong legs, but his upper body (most notably his massive arms) is disproportionally large compared to his lower body.
• Trademark Favorite Food: He is fond of eating Kanzlok, a Unopan-favorite snack consisting of live and sad-looking alien grubs that squeal as they wiggle about, which puts off his friends. The one time he shares them with Tech Jacket, however, she finds them to be delicious to her surprise.
• Virtuous Character Copy: He's a genetically engineered individual with the ability to recover from injuries and become stronger from it, his primary enemies are what can be described as imperialistic Kryptonians, and he grows strong enough to easily overcome their legendary toughness. Allen is basically a heroic version of Doomsday.
• The Watson: Rather comedically acts as this in the Season 2 teaser trailer, asking Mark — on behalf of the audience — when the world will see more Invincible, and even briefly lampshading the long wait in between Seasons 1 and 2.
• "Well Done, Son" Guy: He comes off as desperately eager to please Thaedus, who he clearly looks up to as a mentor and father figure. Thaedus actually does acknowledge Allen to be a great person and a vital asset to the Coalition; it's Allen's own insecurity over his weakness in comparison to Viltrumites that drives him.
• You Are in Command Now: After Thragg violently kills Thaedus at the end of the mission to attack planet Viltrum, by vote of the council of the Coalition, Allen is made his impromptu successor for the time being of the entire Coalition due to his closeness with Thaedus and comparable power until they can find a proper candidate to succeed Thaedus.

General Telia

Voiced By: Tatiana Maslany

Allen's girlfriend and a high ranking member of the Coalition.

• Adaptation Expansion: In the comics, Telia's only role was as Allen's girlfriend who was a bit of diva and somewhat selfish when it came to other people's feelings. The show version has had her relationship with Allen become more loving and closer in resemblance to Mark and Amber such as going on a date. Furthermore, she's a general in the military forces for the Coalition, and is present through the events of the Viltrumite War, making her an Adaptational Badass while the comic version spent her time buying expensive clothes and hob-nobing with glamorous upper-class friends.
• Adaptation Personality Change: In the comics, Telia was a rather unpleasant diva who, while genuinely loving towards Allen, was also incredibly bossy and selfish and as well as a Child Hater (although she explains it's a common trait among her people). Her animated counterpart, while somewhat of a snarker, is shown to be a lot more pleasant personality-wise.
• Alien Hair: She has strange looking tentacle hair that are stylized into bangs.
• Crazy-Prepared: After Allen went missing and knowing there's a mole in the coalition, Telia took to keeping a very powerful blaster under the bed, much to Allen's surprise.
• Extra Digits: She has 6 fingers for each hand.
• Forced to Watch: She's powerless to stop three Viltrumites from ambushing Allen, and she can barely hold back her tears when they end up brutalizing him after he refuses to tell them information about Mark and Nolan.
• Gondor Calls for Aid: She tells Allen that the Coalition needs more allies after repeated Viltrumite attacks, even though the Viltrumites themselves are making it very difficult.
  Allen: Then good thing I found us one.
• Green-Skinned Space Babe: Well, blue-skinned, but all the same, she's an attractive, humanlike alien woman.
• Hypocritical Humor: She calls the live "Kanzlok" that Allen eats at the diner disgusting... while she eats a similarly disturbing live alien that also starts eating the Kanzlok.
• The Lancer: Once Allen takes over as head of the Coalition of Planets, she effectively becomes his number two, helping support him as he adjusts to his new role and backing him up during council meetings.
• The Mutiny: After Pikell blasts the solar disk rather than move the disk, thus endangering Nolan and Allen, Telia decides to commandeer the Venture for herself and take over as captain, helped by the fact that the rest of the crew all immediately side with her.
• Naughty Tentacles: After she and Allen start to shag, she sprouts tentacles.
• The Noseless: She has no nose.
• Red Herring: After it is revealed that there is a mole, the show seems to lightly play up that she is the mole in question, with a few suspicious moments and shots. Fortunately, it's someone else.
• Secret-Keeper: Initially she's Locked Out of the Loop about Allen's investigation into the Viltrumite mole but it's only a day before she's able to cajole her boyfriend into telling her.

Data Twins

Voiced By: Jay Pharoah (Data Twin I), Fred Tatasciore (Data Twin II)

A pair of twins that act as mission control for the Coalition.

• Bizarre Alien Biology: Headshots don't have any more nor less effect on them that a gunshot to the upper arm would have on a human, and doesn't impair their mental functions.
• Boom, Headshot!: Once Data II's betrayal is revealed, Data I blasts his skull. He doesn't die from it, however.
• Dirty Coward: The fat Data Twin sold out the Coalition to the Viltrum Empire all to save himself, believing they would lose the war. Even dirtier, he used his partner's comp to do so.
• Et Tu, Brute?: Data I shoots Data II in utter rage after realizing that he sold out the Coalition to the Viltrum Empire and even used his comp to lower the shield so the Viltrumites can invade.
• Fat and Skinny: Data I is the Skinny, while Data II is the Fat.
• Fat Bastard: Data II, the fat half of the duo, turns out to have sold the Coalition out to Viltrum.
• Mission Control: Their role is to serve as this from their station at the Coalition HQ.
• The Mole: Data II was the one feeding information to the Viltrumites and the one to lower the defenses in Talescria for their counter attack there.
• Once Done, Never Forgotten: They never miss the opportunity to nettle Allen for mistaking "Earth" with "Urath" and spending years going to the wrong planet. Even when Allen brings up this actually ended up helping the Coalition in the long run, they still treat him like a joke.
• Undying Loyalty: The skinny Data Twin is fiercely loyal to the Coalition; to the point of shooting his counterpart when he finds out he's a traitor.

The Venture

Voiced By: Scott Aukerman (Captain Pikell)

• Adaptational Wimp: The crew were still chumps in the comics, but the ship itself being an unreliable jalopy is new to the show.
• Affectionate Parody: It's the Enterprise from The Next Generation, if Picard was a complete buffoon and the Enterprise was a floating garbage can that is always on fire and/or falling apart à la the Millennium Falcon.
• The Alleged Car: The ship barely qualifies as space worthy, with panels falling off and fires randomly breaking out all over, but its crappiness works in the Coalition's favour since no Viltrumites would suspect it.
• Beneath Suspicion: Telia recommended the Venture precisely because it's the least likely to catch any attention.
• Cast of Expies: The crew consists of four alien members who are each based off leads in Star Trek: The Next Generation; Pikell the bald, red uniformed, captain, Tuva the beautiful ship's councilor, Worg a burly bearded alien in yellow, and a robot named Download also in yellow.
• Disposable Vehicle Section: General Telia and the Venture Crew are forced to leave on an Escape Pod when the ship goes critical, with Mark, Zoe, and Allen staying behind to cover Oliver and Nolan.
• Explosions in Space: When the ship blows up, it results in an explosion that looks just like any airbourne explosion on Earth.
• General Failure: Pikell is the captain of the Venture and also a colossal idiot who makes harebrained decisions like parking the ship in an asteroid field and blowing up a solar disc that was holding a race of bloodthirsty saurian aliens at bay. After the Ragnarr fiasco, Telia takes command of the ship while Pikell is demoted, though he retains a position on the bridge, overseeing the ship's systems.
• Going Critical: Barely a minute before the ship actually explodes, Pikell and Tech Jacket both notice a catastrophic system failure in the ship.
• Small Name, Big Ego: The captain sincerely believes his ship to be be the finest in the fleet, in reality it can only hope to one day be a piece of crap.
• Too Dumb to Live: Pikell was willing to leave the Venture parked in an asteroid field. What more needs to be said?
• We Hardly Knew Ye: It is blown up by a Viltrumite Cruiser when the coalition is ambushed.
• Where No Parody Has Gone Before: Unlike most examples, it's a Next Generation parody as opposed to one of The Original Series.

Battle Beast

Voiced By: Michael Dorn

A lion-like alien that was employed by Machine Head who wanted to seek worthy combatants. He later joins the Coalition of Planets to fight in the Viltrumite War.

• Achilles' Heel: His lack of Flight. While no less dangerous, he's significantly handicapped if he has to fight in space, requiring him to wear a jetpack so he could move around. Thragg takes him out of the fight by disabling his jetpack and tossing him far away, preventing him from rejoining the battle.
• Actor Allusion:
  • As a case of Named by the Adaptation, Battle Beast's species is called Dornians, just like his voice actor, Michael Dorn.
  • His Blood Knight attitude also well suits Dorn's experience playing a Klingon, albeit taken to more savage heights.
• Adaptational Villainy: Downplayed. From what we've seen in the comics, he wasn't exactly fond of killing innocents, and he was mostly fighting against someone who could fight back. In the show, he's seen killing weaker aliens than him, but in most cases they were still trying to attack him, meaning he's still never seen going around killing the defenseless. So while he lacks the explicit refusal to kill innocents from the comics, there's nothing to really indicate he does want to go after them in this version. 
• Adaptation Distillation: In the comic, Battle Beast does see something different in Mark, offhandedly saying he’s the best of the bunch there but it’s not enough even as he effortlessly beats him down; in the show Battle Beast spares no special comments to Mark and lumps him with everyone else as equally not worth his time.
• Aliens Are Bastards: A particularly bloodthirsty alien who lives for nothing but brutalizing and eviscerating anyone whom he thinks is a worthy combatant.
• A Beast in Name and Nature: Goes by the moniker Battle Beast, and he is a shameless Blood Knight with the appearance of a white lion-like creature.
• Blood Knight: Absolutely adores fighting and wants to find strong opponents. He laughs when Robot's Chest Blaster actually manages to leave a (minor) burn on him, and becomes absolutely ecstatic at the prospect of fighting Viltrumites. He lives for combat after all.
• Bloodlust: He licks Invincible's blood off of his face, after he opens his arms out and lets the hero's blood splatter against him from the impact of Battle Beast's mace.
• Blue-and-Orange Morality: His entire existence is devoted to fighting, which means he views his friends and allies purely through the lens of whether or not they have promised him a satisfying battle. Machine Head earned his temporary loyalty by having him fight Invincible and the new Guardians of the Globe, though he finds the fight unsatisfying and leaves halfway in. Later on, he allies himself with Allen after Allen promises a fight with Viltrumites, and when it looks like it might not happen, Battle Beast not-so-subtly implies he’s going to tear Allen apart if it turns out he was lying. Fortunately for Allen (and Battle Beast), he gets his desired fight.
• Barbarian Long Hair: He is a savage warrior with an impressive baritone voice and has a long flowing mane like a lion, in addition with some of it being arranged in braids.
• Braids of Barbarism: Has twin braids, and is very barbaric.
• The Bus Came Back: After being absent throughout Season 2, he makes a return in Season 3 as a fellow captive of Nolan and Allen.
• Carry a Big Stick: He charges into battle carrying a massive golden flanged mace, which he puts to good use not only on Invincible's stomach, but also anyone he fights.
• Casting Gag: Voiced by Michael Dorn, who was infamous for playing the codifier for The Worf Effect (who incidentally also sought honor through deeds in combat). In contrast, Battle Beast is the one handing the beatdowns out until he gets one from Thragg who quickly destroys his breathing mask and jetpack before sending him flying away from Viltrum.
• Cats Are Mean: He's a lion-like alien and a ruthless bloodthirsty combatant.
• The Comically Serious: He speaks in the exact same theatrical manner no matter the situation, most notably when everyone is talking about their final meal before they go to war, his answer is a long-winded declaration about how his will be "his own blood as he chokes on it".
• Curb-Stomp Battle: Does this to Invincible and the entire Guardians of the Globe, easily subduing Invincible and throwing around the Guardians like rag dolls while also delivering blow after devastating blow on their strongest. He even gets to deal it out on one of the Viltrumite executioners later, completely ripping him into pieces while receiving no notable damage himself, while being at a terrain disadvantage to boot. During the battle of Viltrum, despite still being at a disadvantage and having his jaws covered by a breathing mask, he manages to dish out beatdowns to several Viltrumites. Thragg easily removes him from the fight, but primarily due to those disadvantages.
• Death Seeker: He isn't just searching for a Worthy Opponent that can beat him in battle — he's actively seeking out a foe who will be able to kill him in combat. This is why he's positively gleeful when Allen breaks him out of his cell in the Viltrumite prison, relishing in the idea of dying at the hands of a powerful Viltrumite warrior.
• Evil Is Hammy: While Battle Beast is mostly composed, once he gets on a good fight, he really chews the scenary.
  Battle Beast (to Allen, while raising his arms up): You promised me more. More battle. More glory! MORE WORTHY OPPONENTS! MORE!
• Foil: To the Vilturmites. Battle Beast actually is an honorable warrior, whereas the Viltrumites only claim to be. For all their bluster about respecting strength and battle, the Viltrumites are routinely enraged and indignant whenever an opponent manages to put up a fight against them. They're also willing to use underhanded methods to eliminate other species strong enough to pose a threat to them instead of enjoying the challenge. This shows that all the Viltrumite talk of respect for strength is ultimately just an excuse to dominate the weak; they have no interest whatsoever in honoring strong opponents with a fair fight, making Viltrumites little more than a universe-spanning group of bullies. Battle Beast, in stark contrast, has made it his life’s mission to battle strong opponents, has no interest whatsoever in fighting those weaker than him, and his ultimate desire is to be slain in battle by a superior adversary, taking his respect for strength to a fanatical degree that the Viltrumites wouldn’t dare reach.
• Giant Space Flea from Nowhere: He's a powerful intergalactic warrior searching for worthy opponents and nearly kills the heroes. How the hell an Earth-based crime lord like Machine Head managed to contact and hire him is anyone's guess. It's been outright compared to The Kingpin summoning Thanos for a street fight.
• Great White Feline: Is a white lion-like alien and the most formidable foe Invincible faces until the Viltrumites.
• A Hero to His Hometown: He's the venerated champion of his home planet, but rampages throughout the galaxy, fighting heroes and villains alike, in search of a Worthy Opponent.
• Humans are Insects: His closing remarks to the Guardians right before teleporting away from their fight.
  Battle Beast: Pathetic. This battle is beneath me. There is no honour in killing insects.
• The Juggernaut: He beats the hell out of Invincible and the new Guardians with only a burn from Robot to show for it. They survived only because he left, calling their fight a disappointment. Season 3 shows that he's possibly stronger than Viltrumites, being able to savagely kill one despite being at a terrain disadvantage (i.e. the vacuum of space). Keep in mind, Allen and Nolan, two very powerful characters, had to team up to do to one of the Viltrumite executioners what Battle Beast did to the other one all by himself, all while having said terrain disadvantage. Correspondingly, in Season 4, finding and recruiting him becomes one of the goals of the Coalition of Planets for their upcoming war against the Viltrum Empire, though they fail in locating him during Nolan and Allen's initial spree of locating potential allies and weapons against the Viltrumites. It's telling that so far the only thing that's stopped him is Thragg while Battle Beast was at a sizable disadvantage.
• King of Beasts: Shares a likeness with Earth's lions and has the combat abilities to back it up.
• Knight of Cerebus: He is the first threat Mark and the Guardians face that is completely out of their league. It's clear that he could have killed them all with little effort on his own if he wanted to, and puts the strongest heroes present on life support.
• Lightning Bruiser: He's fast enough to blitz Invincible, a natural flyer, and completely outmaneuver the other Guardians easily, while being strong enough to brutalize them with simple blows and throw them around like ragdolls.
• Never Hurt an Innocent: Zig-zagged. As part of Battle Beast's Adaptational Villainy, he doesn't really care if innocent people get in the way of his battles, and if weaklings happen to die as a result of the glorious combat that Battle Beast wants, he's not going to lose any sleep over it. That being said, Battle Beast doesn't go out of his way to hurt innocent people, either. Not because it's morally wrong to do so, but because there's no point to him in fighting someone who can't put up any kind of resistance. It's less malice and more apathy — he won't go out of his way to kill them, but he's not going to care if they're in the line of fire.
• No Challenge Equals No Satisfaction: After crushing most of the heavy hitters of the Guardians of the Globe, he feels the rest are too easy to fight and decides to leave.
  Battle Beast: There is no honor in killing insects.
• No-Holds-Barred Beatdown: What his fight with Invincible and the Guardians amounted to. Invincible, Monster Girl, and Black Samson got the gruesome worst of it and end up hospitalized. He also ripped the body of the Viltrumite that he fought completely apart.
• Noodle Incident:
  • It's unknown how an Earth-based crime boss like Machine Head was able to get a handle on a powerful space-faring being like him. Though Machinehead's quantum computing coupled with Isotope's teleporting ability might have gotten his attention, Battle Beast shows he can make his own way in space.
  • How he became a prisoner on board a Viltrumite prison ship is another mystery that's never answered though it can at least be inferred, based on his dialogue, that he's been actively seeking to challenge a Viltrumite in battle, presumably due to their fearsome reputation as unstoppable warriors.
• No-Sell: The heroes' attacks barely even scratch him. Robot managed to leave a burn scar, but it's a flesh wound to Battle Beast at best.
• Not in This for Your Revolution: He ends up joining the Coalition in their war against Viltrum. Not because he believes in their cause or anything but because he craves glorious battle and fighting the Viltrumites is the hardest and most glorious fight you can get.
• Not Worth Killing: Why he ends up bailing on the fight against the Guardians. After beating their strongest fighters so savagely that they're on the verge of death, he decides there's "no honor in killing insects" and leaves rather than continue an unchallenging fight.
• Odd Friendship: He shares this with Allen the Alien who manages to convince him to side with the Coalition to fight the Viltrumites and invite him along for missions against them.
• One-Man Army: He alone does more damage to Invincible and the Guardians than Machine Head's entire gang combined.
• Pet the Dog:
  • Notably, he keeps his agreement with Allen to leave Nolan alone after being given a fight with Viltrumites as Allen promised.
  • After being found by traders and brought to the Coalition of Planets, he doesn't antagonize anyone and just patiently waits for Allen to return. For someone as infamously blood-thirsty as him, that's at least a sign of respect for Allen (though it may just be an indication that he doesn't think anyone in the Coalition is worth fighting).
  • While heading to planet Viltrum for what is the final battle of the Viltrumite War in hopes of a Decapitation Strike, Battle Beast is still his usual battle hungry self but he emphasizes the importance of nutrition before battle when Zoe is struggling to eat due to her nerves and, when the others in the room begin reminiscing about what meals they'd think to have as their last as a hypothetical, Battle Beast earnestly joins in the discussion in his own graphic way.
• Red and Black and Evil All Over: His suit is mostly black with red gloves and accents. Along with a dash of White and Red and Eerie All Over due to his white fur.
• Screw This, I'm Outta Here: He leaves without actually finishing off the Guardians of the Globe because he was unsatisfied with their fight. It inadvertently saves their lives as a result.
• Shout-Out: He is likely a reference to the 1980s toyline "Battle Beasts," which were humanoid animal toys in armor and wielding weapons. The connection is furthered by the fact that the flagship character from the line is a white lion.
• Sorting Algorithm of Evil: His first appearance plays with this; he's introduced and looks, at first, like a random mook working for Machine Head, but he's actually so powerful he can effortlessly curbstomp the entire new Guardians all on his own.
• Strong and Skilled: He is both incredibly strong, even more so than a Viltrumite, and also incredibly skilled in combat. Combining his skills and his strength and he is able to take on Viltrumite warriors at his best, and pretty much utterly decimate anyone else without breaking a sweat.
• Super-Strength: Proves to be far stronger than both Invincible and Monster Girl, leaving them bloody and battered with the force of his blows.
• Threat Backfire: Being an extremely powerful Blood Knight and Death Seeker rolled into one, it should go without saying that death threats won't work on him.
  Viltrumite Executioner: [after taking several hits] I'll kill you for that.
  Battle Beast: Is that a promise?
• Token Evil Teammate: He is the only warrior from the Coalition's war effort not to end the Empire's tyranny, but so he can have glorious battles with worthy opponents, and so far the Viltrumites more than fit the bill.
• Token Flyer: Inverted, he's notably the only top tier heavy hitter who doesn't have flight as part of his default power set. He doesn't even normally have a vehicle like Space Racer.
• Wake-Up Call Boss: Battle Beast is an Omni-Man level alien warrior that was hired as security for Machine Head. In fact, during his introduction it's very easy to mistake him for just another colorful hired thug no more impressive or dangerous than the rest. He then proceeds to annihilate Mark, and nearly kill Monster Girl and Black Samson all the while tanking through every attack thrown his way. He trounces the Guardians so easily that he just leaves out of boredom.
• Wild Card: Battle Beast cares for only one thing: glorious battle. In Season 1, he beats Invincible and half of the Guardians of the Globe to near death but leaves without finishing them off because he found their fight unsatisfying. In Season 3, he helps Allen free Nolan from a Viltrumite prison but almost turns on him when it seemed like he'd been lied to about there being Viltrumites present, and in Season 4 he assists the Coalition on stopping the Viltrumites, because he'd get a good battle out of it. Basically, if you're able to point him in the direction of a good fight, he is your ally. If you aren’t, he's your enemy (and God help you if you are).
• Worf Had the Flu: During the battle of Viltrum, he's stuck just with a jetpack and a breathing mask preventing him from using his jaws, meaning he's fighting Viltrumites at a significant disadvantage. He still manages to manhandle most of the Viltrumites he fights, but it does allow Thragg to remove him from the battle by destroying both and throwing him into deep space.
• World's Strongest Man: Battle Beast is renowed as the most powerful and legendary warrior of his planet, with his motivation for setting course for space and subsequently joining the war against the infamous Viltrumite Empire being to find someone strong enough to best him in combat and grant him the glorious death he is seeking. He's got a legitimate claim to being the most powerful non-Viltrumite in the universe, as he's shown able to kill one of the Executioners in a one on one fight whereas it took Allen and Nolan (though one weakened from his near execution) working together to kill the other one. 
• Worthy Opponent: He practically salivates at the notion of getting to test his strength against Viltrumites. After eviscerating his opponent in the jailbreak and spending an unknown length of time frozen and dormant in the depths of space, his very first concern upon awakening is "More." 

Geldarians

• Clingy MacGuffin: Their tech jackets aren't meant to be removed, and they're permanently bonded to their hosts for life. One Geldarian giving their jacket to Zoe was a one-in-a-million fluke.
• Gadgeteer Genius: They were able to build the "tech jackets" — extremely versatile suits of Powered Armor that were strong enough to resist a viltrumite invasion. So the Empire responded with Orbital Bombardment, and now they're an endangered species.
• Virtuous Character Copy: Very similar to the Reach of Blue Beetle comics, being a race capable of building Do-Anything Power Armor. Though they are victims of imperialism, rather than perpetrators.
• Weak, but Skilled: Biologically, they're actually weaker than baseline humans, and they need their tech jackets to function. Still, with the jackets, they're able to fight viltrumites on a semi-equal level.

Thraxans

An insectoid alien race inhabiting the planet of Thraxa and the subjects of their monarch, Omni-Man.

• Alien Blood: Their blood is dark blue, in contrast to their medium blue skin. In the comics, however, their blood was pink.
• Aliens Never Invented Democracy: While far from tyrannical, Thraxans simply let their oldest member become their ruler until they die. For the purposes of the story, this system only serves to make Nolan the temporary Emperor of the Thraxans while he is exiled there.
• Always Lawful Good: From what's been shown of them, they are shown to be a kind, peaceful alien race that only show kindness and gratitude to those who save them, with not a single evil member to be found.
• Blue-and-Orange Morality: Collectively, a very benevolent one. Due to being a short-lived species capable of perfect recall of their lives, they have a far greater appreciation of life and a gentle appreciation of death, making them very aware of their mortality, and they don't have time to dwell on the past. If someone harms another but tries to redeem themselves, the Thraxans will immediately Turn the Other Cheek and move on with their lives rather than hold a grudge.
• Curb-Stomp Battle: Like so many different species before them, they're easily wiped out by the Viltrumites and stand absolutely no chance against them.
• Innocent Aliens: While they're willing to lie to Mark to bring him to Nolan, they have no bad intentions in doing so and are simply following the orders of their king. The Thraxans are a friendly and peaceful people by all appearances.
• Insectoid Aliens: They resemble some kind of bizarre alien mantids.
• Mono no Aware: They are fully aware of how short their lifespan is, and it's given them a gentle appreciation of death.
• No Infantile Amnesia: Thraxan young are noted to have perfect memory of their life even into their adulthood, a trait that also gets passed into Oliver.
• Photographic Memory: They have perfect memory of their life, even as infants.
• Short-Lived Organism: They age much faster than humans. The one sent to bring Mark to Thraxa complains that he's spent most of his life on the journey… one that only takes two weeks at maximum from Thraxa to Earth and back.
• Too Good for This Sinful Earth: Some of the friendliest aliens we've seen so far, and they're slaughtered by the thousands during the Viltrumite invasion. Subverted, as the species survives to rebuild with Mark's help.
• Turn the Other Cheek: According to Nolan, the Thraxans are so aware of their mortality that they don't have time to dwell on the past. For them, if someone harms another but tries to redeem themselves, they forgive immediately and move on with their lives rather than hold a grudge.
• Walking Spoiler: Mostly by virtue of who they answer to: Nolan Grayson.

Andressa

"Séance Dog" (Nuolzot)

^{True Form}

Voiced By: Rob Delaney

A magical dog from another dimension where magic and dogs are real, as well as the star of Mark's favorite comic book. In actuality, he's a Thraxan sent to bring Mark to Thraxa.

• Eskimos Aren't Real: As part of his introduction as Séance Dog, he says he is from a dimension where, along with other more understandable comparisons, dogs are real, implying he believes on Earth, they are not.
• Expy: A double one. Séance Dog (the comic character, not the alien) serves as a stand-in for Science Dog from the original comic (who couldn't be used due to being considered a separate license from Invincible), while also being clearly modeled on Doctor Strange.
• A Form You Are Comfortable With: Attempted and failed comically. He tries to take the form of something Mark loves to talk to him, but ends up just freaking him out since he takes the form of a talking cartoon dog.
• Large Ham: When Nuolzot is in his Séance Dog form, Rob Delaney uses a voice that is almost certainly intended to be an impression of Matt Berry.
• Nice Guy: While bumbling and willing to lie to complete his mission, he's a sweet guy who's just doing his job and is nothing but friendly with Mark and William.
• Poor Communication Kills: He nearly gets his head beaten in by Invincible when Mark quite understandably freaks out at seeing a comic book character appear at his dormitory.

Rognarr

A non-sapient species of reptile-like aliens that Omni-Man encountered while still serving the Viltrum Empire.

• Achilles' Heel: Their only notable vulnerability is their sensitivity to extreme cold temperatures, slowing down and eventually freezing solid. Though this is only relative to other superpowered beings, and they revive from their stasis no worse for wear if ever allowed to thaw.
• The Dreaded: They are considered some of the most dangerous creatures in the galaxy for a reason. Even the Viltrumites considered them a problem and resorted to freezing their planet instead of dealing with them directly. In his novel Savage Planet, Savage Beasts, Omni-Man recalls how he was barely able to escape from their planet alive. Later, when he and Allen are surrounded by several hostile Rognarrs, Omni-Man somberly notes that they are going to die in no uncertain terms, with only a last-minute intervention by Telia saving them. They even scared Conquest and left him with lasting trauma over taking his arm and eye from him in a fight.
• Godzilla Threshold: They were so dangerous, the best solution the Viltrumites could find to prevent other people from finding out the Rognarrs could kill them was to place a disk on their solar system's sun and cause their planet (as well as two others in the vicinity) to be completely frozen. Later, the fact that the Viltrumites considered them dangerous led them to be poached by the Coalition as Beasts of Battle despite them being insanely aggressive monsters as strong as Viltrumites.
• Harmless Freezing: Downplayed. Once they are unfrozen they can still fight with astonishing ferocity, though Nolan notes that they are still not at full strength.
• Heavyworlder: The Rognarrs' Super-Strength is due to the planet they live on having gravity that is so dense that even Viltrumites have a hard time moving around in it.
• Homefield Advantage: What makes the Rognarrs such a threat to Viltrumites is their home planet's naturally high-density gravity, giving them a massive advantage of slowing the latter group down. When faced against Viltrumites outside of their home planet's naturally high-density gravity, the Rognarrs become marginally less dangerous.
• In a Single Bound: The Rognarrs are unable to fly, but their ability to jump super high, even with their planet's increased gravity, more than makes up for it. They can easily catch up to Nolan and Allen as they try to fly away from the planet.
• Lizard Folk: The Rognarrs are largely muscular, semi-humanoid-looking reptilian aliens, giving a dinosaur-like appearance.
• Nigh-Invulnerability: The Rognarr are shown shrugging off repeated blows from both Nolan and Allen (who, at this point, is strong enough to rival Viltrumites in power), at best getting knocked around without any real injury. They can be killed; a few are shown falling in battle during the battle over Viltrum, but they are the toughest alien species yet seen and especially resistant to blunt force, even from other super-powered beings.
• Non-Malicious Monster: They are simply really aggresive, territorial space creatures.
• Super-Strength: They are arguably the strongest species in the entire universe. Even the Viltrumites struggled to deal with them, resorting to freezing their planet instead of taking them on directly. They are shown to be a match for notably powerful characters like Nolan, Allen, and even Conquest.
• The Worf Effect: To highlight how dangerous these things are, one of them was able to kill Nolan's Viltrumite partner with ease and nearly kill him as well. Flashbacks also show that a pack of them managed to rip out Conquest's arm and eye, though he was suffering from the Scourge Virus at the time. Later, when deployed at the battle of Viltrum, they rip apart Viltrumites like they're made of tissue paper (though the same is shown to apply to them now that the Viltrumites aren't constrained by their homeworld's immense gravity).
• Worf Had the Flu: As Allen is just barely holding one at bay and trying to reassure Nolan that he can handle it, Nolan immediately corrects him by stating that the Rognarr are still half frozen and not up to full strength. The same Rognarr just absorbed a full-body shoulder tackle from Nolan and barely even budged.
• Zerg Rush: As if their ridiculous strength and ferocity weren't enough, they have absolutely no compunctions with absolutely swarming any intruders unlucky enough to end up in their midst, and Conservation of Ninjutsu very much isn't in effect here.
