• Appleseed (2004). While Deunan is trying to deactivate the attacking robots at the end of the movie, her dead mother finishes entering the abort code for her and saves the day.
• How Mato found Yomi when she went to the Otherworld in Black★Rock Shooter; through the help of the eponymous being; if one goes by the "BRS is a spirit" interpretation.
• Cardcaptor Sakura: Sakura's mom, Nadeshiko, catches Sakura after an illusion (of Nadeshiko, go figure,) tricks her into walking off a cliff. Nadeshiko reappears at the end of the episode long enough to see Sakura off to school before vanishing again.
• Code Geass: Lelouch of the Re;surrection: To help CC complete Lelouch’s resurrection, Euphemia, Rolo and (in the manga) Shirley’s souls come to assist her in the process.
• Heartbreakingly Subverted in Digimon Tamers: In a final, desperate attempt to break through the D-Reaper's barrier and rescue Jeri, Beelzemon uses Fist of the Beast King, the attack of Jeri's Digimon Leomon... who Beelzemon himself had killed right in front of her. It succeeds in destroying the barrier, but Beelzemon finds Jeri frozen at seeing her beloved Digimon's attack used by his murderer: she's ultimately paralyzed long enough for the barrier to re-seal itself, and Jeri's emotional wound has been freshly opened for the D-Reaper to keep feeding on her despair. Ultimately, Leomon's help, if it truly was him lending his strength from beyond, served to make everything worse.
• Dragon Ball Z is the trope namer, almost always being fulfilled by Goku:
  • At the end of the Cell Saga, Goku assists Gohan in delivering a superpowered Kamehameha, albeit with more emphasis on emotional support: Goku was technically still in Other World the whole time, but Gohan really needed his father telling him to go all-out. The famous shot of Gohan's one-handed Kamehameha with Goku performing it behind him is therefore metaphorical, but is still one of the most famous images in the franchise and is often taken literally.
  • In Dragon Ball Z: Bojack Unbound, Goku teleports himself out of Other World for an instant and punches Bojack in the face to save Gohan.
  • As pictured above, Goku gives his aid again in Dragon Ball Z: Broly – Second Coming for Goten and an adult Gohan in a rather on-the-nose recreation of the Cell Saga scene. The movie is intentionally vague however as to whether Goku was actually there or not, and doesn't provide a definitive answer.
  • In the Buu Saga, Goku returns to the world of the living for a day, initially for a fun tournament but eventually to take on the various villains of the arc. Later on the same would happen to post-Heroic Sacrifice Vegeta since the situation had gotten THAT desperate, and Goku would return from Other World again via a different loophole, this time for good.
  • Dragon Ball Super would utilize this once again, this time bringing back Frieza from Hell to participate in the Tournament of Power.
• The first DBZ example is spoofed/homaged at the end of Excel♡Saga, when Pedro and his son are helped by the ghosts of every major character who died up to that point, and their combined Kamehame Hadoken blasts That Man into dust, finally rescuing Pedro's wife and the Great Will. The scene is goofy, badass and heartwarming at the same time.
• Aerith at the end of Final Fantasy VII: Advent Children. First, she joins in with the party using a Fastball Special to propel Cloud toward Bahamut SIN; and later, her Level 4 Limit Break heals Cloud's geostigma.
  • In Advent Children Complete, Zack Fair interrupts Cloud's battle with Sephiroth & offers some words of encouragement, even asking if Cloud wants his help. He's ultimately turned down.
• Gundam:
  • In the climax of Zeta Gundam, Kamille uses his Psychic Powers (with a boost from the Zeta's Biosensor) to call for help from the spirits of his slain friends and allies, which shuts down Scirocco's Humongous Mecha and allows Kamille to ram it.
  • Done again at the end of Double Zeta when the spirits of various deceased characters gives Judau's ZZ Gundam a power boost to use against Haman.
  • The Final Battle of Mobile Suit Gundam GQuuuuuuX has Amuro Ray's ghost in the titular Gundam's Omega Psycommu help Machu against Shuji and the "White Devil"/RX-78-2.
• Subverted in Higurashi: When They Cry. In Minagoroshi-hen, Rika's True Companions come back to help her right when the Big Bad is about to ritualistically kill her... with moral support. She does die, but she gets better.
• Shep from Interstella 5555 dies rescuing the band, and comes back to save them from an Eldritch Abomination attacking their ship in the climax.
• JoJo's Bizarre Adventure: Diamond is Unbreakable: Used twice in the part. When Rohan is trapped in the Ghost Alley with Cheap Trick, he uses the hands of the dead that drag you to an unknown location or fate to force the little gremlin off of his back and into Hell itself (with the help of his Heaven's Door ability). Used again at the end of the part when Yoshikage Kira is transported to the same Ghost Alley after he is, well, half-defeated. However, Reimi and Arnold get their revenge on the killer and give him the ending he deserves by getting him to turn around and ultimately get caught by the ghost hands, presumably all of his victims. Later, instead of going to hell, he becomes a ghost hitman featured in his sort of redemption arc, Dead Man's Questions.
• Mermaid Melody Pichi Pichi Pitch has Sara who comes back as a glowing spirit to save Luchia's little pink behind.
• Uchiha Obito from Naruto, in a example which would make Goku proud, dies saving Kakashi, his body turning to ash. He then uses his Kamui ability to teleport out of the Otherworld, without a physical body, to give Kakashi all of his chakra and abilities, which turns to be essential in Kaguya's defeat.
• In Negima! Magister Negi Magi, Jack Rakan forces himself back into existing by sheer willpower, and snaps Negi out of his Superpowered Evil Side. With his fist.
• Sailor Moon:
  • Played With when the Senshi visit the ruins of the Moon Kingdom. In all continuities, the late Queen Serenity appears to them and provides backstory to the Moon Kingdom and the girls' past lives. However, she's not really a spirit, but an interactive holographic projection of the Moon Kingdom computer databanks. The nature of her apparition is more ambiguous later on, when she visits Usagi's subconscious to grant her new powers and give her a pep talk ^note That's anime-only, though; the manga has no such scene, and in the final arc it's outright stated that Queen Serenity had returned to the Galaxy Cauldron upon her death.
  • In the 90s anime, the Inner Senshi die one by one, but their spirits appear to comfort and encourage a distraught Sailor Moon, giving her the strength to go on and face the Dark Kingdom. Later on, when Moon faces Super Beryl, their spirits appear again and lend her the strength to use the Silver Crystal to win the battle.
• Sword Art Online
  • Ordinal Scale: During the final battle with An Incarnation of the Radius, Asuna is shown performing Mother's Rosario, with an ephemeral Yuuki swinging her sword in time. It's left ambiguous whether this is truly Yuuki lending Asuna her strength or just Rule of Symbolism.
  • Alicization: War of Underworld: Yuuki builds upon the example from Ordinal Scale and backs up Asuna in the fight against PoH, and this time she's actually shown voicing moral support to Asuna. Meanwhile, Kazuto is on the verge of being Driven to Suicide in the midst of a Fluctlight-damage-induced Heroic BSoD when Higa connects Asuna, Suguha, and Shino's Fluctlights to his... and when that's not enough, Eugeo steps in to pull him the rest of the way back.
• YuYu Hakusho:
  • When Kuwabara needed to study for an exam while Yusuke was dead, Yusuke went into his dreams and helped him study.
  • He also possessed a girl for a few minutes to beat on some bullies and a few other minor things before being brought back. This is the anime version; that arc of the manga is significantly longer.

• This is pretty much Deadman's entire shtick, especially in his guest star appearances when he's helping out a more "conventional" superhero. Being able to Body Surf pretty much at will helps a lot when it comes to still interacting with the world of the living.
• In DC Comics' Infinite Crisis, while The Flash (Bart Allen iteration) is battling Superboy Prime a rift in the speed force opens up and from it emerge Max Mercury, Johnny Quick and Barry Allen to help him pull Superboy Prime in.
• In The Return of Barry Allen, it is implied that Barry Allen's spirit is watching over his successor Wally West against the imposter. During the final battle with the imposter intent on ruining Barry's legacy, Wally is given an opening when a lightning bolt strikes the ground in front of the villain. West smiles and whispers a "Thank you" to the heavens.
• Wolverine once had to face several of his foes that had gone to hell, and received help from Colossus. Though since then Colossus has been retconned to have never died in the first place, this is not brought up ever.

• The Bridge:
  • The story repeatedly has mention of a 'hot wind' blowing by at key points during the Climax Boss fight with Grand King Ghidorah and the Nightmare Godzilla incident that preceded it. The fic takes inspiration from Rebirth of Mothra 3 with Grand King Ghidorah devours souls to power himself up. While battling him alongside Xenilla, Junior frees those trapped souls who, with aid from Harmony, allow the presence in that hot wind to take shape: Godzilla Senior, who helps his sons destroy the King of Terror once and for all with a Family Spiral Fire Ray.
  • During the 2019 Halloween Special, Destroyah distracts the kaiju sized Giranbo in her pony form so the Cutie Mark Crusaders can escape her realm, despite fully expecting to die in the process. The Crusaders refuse and attempt to power Destroyah up into her kaiju form to save her as Giranbo is on the verge of killing her, but lack the ability to do so on their own. Their resolution inspires the ghosts of the many adults who Giranbo had murdered during their failed attempts to save her countless child victims to rise from the mass grave she threw them in to lend their power to the trio to give them the needed push while guiding their beam, allowing Destroyah to be empowered into her kaiju form.
  • A second example occurs when Giranbo manages to gain an upperhand by exploiting Destroyah's weakness to ice. The Cutie Mark Crusaders realize Giranbo's oven was containing the souls she was preparing to consume and open it, letting them all rush out in mass to disrupt Giranbo's magic and prevent her from being able to use ice magic.
• from porcelain to ivory to steel: Even with DIO controlling his body, Jonathan Joestar's spirit still fights against his brother to aid his descendants and their allies. In the Death 13 arc, his spirit enters the dream world to help Sherry, Jotaro, and Kakyoin against the dream-controlling stand.
• In A Growing Affection, the Reaper sends the first four Hokages back to capture Orochimaru for her. Earlier, Orochimaru calls back a bunch of souls to fight Naruto for him. Unfortunately for him, only one of the five is actually interested in killing Naruto.
• let me be a little less liminal: Ryu-Mieong, who has been dead for twenty-four years, incinerates a pair of demons about to kill her daughter and hides her from Gwi-ma.
• A thousand years into the Dark World of the Pony POV Series, the spirits of the Mane Six's loved ones begin appearing to them to help redeem them. Some have more luck than others.
  • Also pops up during the fight with Odyne!Fluttercruel; after her body is destroyed, the spirits of Fluttershy (who died 500 years earlier) and Pinkie Pie (who died recently) show up and prevent her spirit from possessing anyone else long enough to blast her with the Elements of Harmony and banish her from the mortal plane.
  • During the Final Battle with Nightmare Paradox, Discord distracts the Nightmare to give Twilight time to power up the final spell to defeat her once and for all. By calling her on Anarchy's cellphone from the afterlife. And Trolling her until she's so enraged she forgets she's in the middle of a battle.
• Princess Twilight's 505th Birthday is set centuries in the future, where Twilight and Rarity are immortal, but the rest of the Mane Six died of old age. During the big climax, Twilight escapes the bad guy by astral projecting into the fabric of magic itself—then returns with her four deceased friends in tow. They stick around just long enough to blast the bad guy with the Elements of Harmony, then zip back off to the Elysian Fields.

• Conan the Barbarian (1982): Valeria appears just in time to save Conan from being killed by Rexor, Thulsa Doom's lieutenant.
  Valeria: Do you want to live forever?
• Ghost (1990): At the start of the movie, Sam Wheat is murdered and becomes a ghost. At the end, he saves his girlfriend from being killed by his murderer by accidentally causing the villain's death.
• Ghostbusters: Afterlife: The deceased Egon Spengler returns as a ghost to help his family and fellow Ghostbusters take down Gozer one last time.
• In the remake of House On Haunted Hill, the last two characters are trying to escape from the evil presence, but there is a gate which they can't open. Before they are consumed, a ghost from a character that had entered the house with them under the same pretenses but had died earlier appears and opens the gate for them.
• Kamen Rider W FOREVER: A to Z/The Gaia Memories of Fate: At the film's Darkest Hour, the dead Sokichi Narumi/Kamen Rider Skull appears at the Detective Agency, giving his protégé Shotaro a Driver belt, just in time for when the Heat Dopant attacks.
• The Lord of the Rings: The Return of the King has the heroes recruit help from an army of the dead.
• Mortal Kombat (2021): When Cole starts losing his battle with Sub-Zero, he tries to stab him with Scorpion's kunai. Sub-Zero turns the blade on Cole, cutting the latter's hand with it, but the blood ends up summoning Scorpion from the Netherealm, who helps Cole fight Sub-Zero.
• Star Wars: In The Rise of Skywalker, when Rey proves no match for Palpatine on her own, she manages to call on the Jedi that came before her to even the playing field. What follows is implied to be a battle between not just them, but all the Sith and Jedi who ever lived.
  Emperor Palpatine: You are nothing! A scavenger girl is no match for the power in me! I am all the Sith!
  Rey: And I... am all the Jedi.
• In What Lies Beneath, Claire Spencer appears to be terrorized by the spirit of a woman named Madison, but as the story progresses, it becomes more evident that Madison's actually trying to warn her— she was murdered by Claire's husband Norman and is trying to prevent her from becoming his next victim. During the climax, Madison reanimates her own corpse to take Norman down once and for all, saving Claire's life and avenging her own murder.

By Author:

• A couple of examples by Robert E. Howard:
  • In Queen of the Black Coast, this role was fulfilled by Belit, the title character of the story, as her spirit intervenes to save Conan from a supernatural horror.
  • In the poem The Return of Sir Richard Grenville, the ghost of the eponymous worthy (who was a real life historical figure) appears to fight side-by-side with his comrade-in-life Solomon Kane.

By Title:

• In Alternate Routes by Tim Powers, the ghost of the protagonist's late wife intervenes to help him a few times during the climactic struggle. Thanks to one of the stranger features of the afterlife featured in the novel, he also gets assistance from the ghost of their daughter who never existed in the first place.
• In Aunt Dimity's Death, Dimity helps Lori get rid of an unwelcome visitor (Dr. Evan Fleischer, an obnoxious college classmate) who invites himself to her cottage. She literally slams the door in his face, makes the cottage turn strikingly cold when he enters anyway, fills the living room with smoke from the fireplace, and causes him to break a tooth on one of Lori's oatmeal cookies (which "contained nothing more tooth-threatening than some chewy raisins.")
• The Beginning After the End: In the series finale, Arthur, his bonds, and Tessia are in the aether realm trying to prevent The End of the World as We Know It. As aether is essentially the essence left behind by magical beings when they die, the final stretch sees them being assisted by the specters of deceased loved ones and allies in the following order: Aldir, Director Goodsky, Angela, Alduin and Merial, Adam, Blaine and Priscilla, Jarrod, Doradrea and Theodore, Alea and Olfred, Jona and Cedry, Lauden, Taegen, Sulla, Baldur, Enola, Rinia, and finally Reynolds.
• The Dresden Files:
  • In Book Three, Harry is being hunted by a ghost who vastly overpowers him. So what does he do? He DIES. But he has someone resuscitate him so he can then team up with his ghost. (In the Dresden Files universe, ghosts are spiritual "imprints" of the dead, not the dead themselves.)
  • In Book 13, he is the backup, after having arranged his own death. And then he arranges for more otherworldly backup when he has to storm the castle, in the form of an army made up of hundreds of ghostly murderers and serial killers.
• It's a pretty minor thing, but in Galaxy of Fear: Ghost of the Jedi, Aidan Bok helps Tash call on the Force to make the Big Bad's aim falter. He then scouts for her as she flees, telling her what is where and how to shut down a machine in a rather more direct, precise kind of advice than most ghosts are known for.
• In the first Green Rider book, Karigan gets possessed by the ghost of F'ryan Cobblebay (Green Rider and swordmaster in training) while fighting the renegade Weapon Torne. Between the sudden change in skill level and the anti-theft spell on the brooch Torne had stolen from Karigan, F'ryan was able to defeat Torne.
• Harry Potter:
  • In Harry Potter and the Goblet of Fire, the "ghosts" that spring out of Voldemort's wand during the Priori Incantatem effect rush Voldemort when Harry breaks the connection. While they can't actually harm or restrain Voldemort, their ghostly forms obscure his vision for a few seconds, allowing Harry to escape.
  • In Harry Potter and the Deathly Hallows, Harry uses the Resurrection Stone to bring back the ghosts of his parents, Sirius and Lupin to give him moral support when he confronts Voldemort.
• His Dark Materials: In The Amber Spyglass, during the climactic battle between the Authority and Metatron's forces and Asriel's rebellion, some of the ghosts that Lyra and Will freed from the World of the Dead voluntarily retain a cohesive form for a while in order to fight off the Spectres preying on the battlefield, before dissolving and becoming one with the universe. The Spectres eat the souls of adults, but since the ghosts are only one third of a whole being (the "mind" of "mind, body and soul") and their dæmons faded away upon death, the Spectres can't harm them, while they can physically restrain the Spectres.
• The Locked Tomb: In Harrow the Ninth, the ghosts of a number of characters who died in the first book help the still-living Harrowhark fight off an attack by a malevolent ghost, then head off to join another character's battle against a Resurrection Beast.
• The Lord of the Rings: The Return of the King had the heroes recruit help from an army of the dead. The army is incapable of actually fighting, but their mere presence terrifies the enemy into fleeing.
• Miles Pennoyer: Psychic detective Miles Pennoyer uses his training to communicate with powerful spirits from beyond the veil of death on multiple occassions. Some short stories that feature this trope include:
  • "The Cast of the Moon Child": In order to combat a moon-worshipping cult intent on summoning the antichrist, Pennoyer calls upon the aid of various psychic masters from the spiritual plane. They are able to assist him in destroying the Cult's leaders with incredible displays of power, appearing to bystanders as towering flames surrounding Pennoyer's body.
  • "The Woman on the Stairs": When he suspects a mysterious Russian princess of hosting the vampiric spirit of an ancient Tibettan monk, Pennoyer enlists the aid of a long-deceased Buddhist master who knew the evil monk in life to expunge his influence.
  • "The Case of the Double Husband": Not Miles, but Ted Eliot is able to bargain with "the Wise Ones"/ "Those on the Other Side"/ "Elder Brothers" (i.e. psychically powerful beings who have some sway over who passes into the afterlife and who must reincarnate to pay their karmic debts) when his best friend George Arnold is on death's doorstep. Miles intuits that this has happened after the fact.
• My Next Life as a Villainess: All Routes Lead to Doom!: Atsuko enters Catarina's mind to awaken her from her magically-induced coma, though she arrived from her reincarnation's subconscious rather than the afterlife.
• Nina Tanleven: In books 2 and 3, Nine and Chris are threatened by a gun-toting villain and are saved by a ghost whom they've been trying to help - Captain Gray and Cornelius Fletcher, respectively.
• Necromancers in Kelley Armstrong's The Otherworld series often get assistance from the dead, usually in the form of advice or spying, although in one book a poltergeist (telekinetic ghost) provided some more direct assistance.
• In Splinter of the Mind's Eye, the very first novel of Star Wars Legends, it's not actually stated that Obi-Wan Kenobi briefly possessed Luke Skywalker in order to fight off Darth Vader, but considering the sudden dramatic uptick in Luke's dueling skills and the fact that he told the Sith "I am Obi-Wan", this is generally what fans assume happened.
• In Warrior Cats, the Last Hope, which was originally intended to end the series, the Dark Forest, effectively Cat-Hell, invades the world of the living, and the clans are only saved when Star Clan and the Tribe of Endless Hunting, the Cat-Heavens, join the fray. Every cat who has died over the course of the series is fighting either for Cat-Heaven or Cat-Hell in the final battle. However, given how large the cast is, most go unmentioned aside from the most prominent personal encounters.
• The Wheel of Time: This is the function of the Horn of Valere, which is inscribed with "the grave is no bar to my call." However, it has a rather specific stipulation about usage - "Let whosoever sounds me think not of glory, but only of salvation" - and it is bound to whoever blows it. No one's entirely sure where it comes from or how it works, to the point where it borders on Wrong Context Magic. All anyone knows is that it summons constantly reincarnated dead heroes - with the exception of the Dragon. Usually they live in Tel'aran'rhiod in between reincarnations, and heroes are occasionally added to the horn as Noal Charin a.k.a. Jain Farstrider is at the end of the series. While summoned, they remember all their past lives and are incredibly, if vaguely, powerful - there's only a hundred of them, but they can devastate vast armies.
  • Things get complicated partway through the series when one of the Heroes of the Horn, Birgitte Silverbow, intervenes on behalf of the heroes in Tel'aran'rhiod (which is against the rules), and gets blasted out of the Dream into reality. Unlike normal reincarnations, she's a woman in her prime with all her memories, but is otherwise a normal woman (just an absurdly good archer). As the series goes on, she starts losing her memories, and it's feared that she might have been permanently separated from the Horn. In A Memory of Light, however, she is killed and then immediately re-summoned when Olver blows the Horn, proving that she's just fine.

• Possibly the end of season two of Being Human (UK) where Annie takes the evil priest through the door.
• Charmed:
  • Dead relatives of the Charmed Ones pop up quite often (with one notable exception) to assist, give advice both on magical and mundane problems, and sometimes outright defeat the Demon of the week. Grams often uses her telekinesis from the afterlife to flip the pages of the Book of Shadows and help her granddaughters without manifesting herself. She's also the one who's summoned the most by the Sisters. Patty appears to Prue first and Piper then while they're about to drown, to help them overcome their fears – of drowning itself and of leaving her baby motherless respectively – and save themselves.
  • The first and perhaps most iconic instance, though, is when the Charmed Ones summon their ancestor who originated their bloodline and the Charmed Ones prophecy: Melinda Warren. Notably, she manifests as a corporeal entity and has a lot of magical and familial interactions with the Sisters before helping them vanquish an ancient Warlock.
  • Phoebe comes up with a spell she believes is powerful enough to vanquish the Source of All Evil: it involves calling upon the magic of the entire Warren line of Witches to assist them. It works.
    • The same spell is used to call upon the Magical Romani lineage of Ava and help her vanquish the Demon who was hunting her family. In that instance, the ancestors' spirits visibly manifest and even deflect the Eye Beams the Demon throws at her.
  • The Warren ancestors are also called upon (via another spell) to assist with the wiccaning of the Charmed Ones' children, with Grams's spirit officiating the ceremony. In that occasion they manifest themselves and we can get a glimpse of them.
  • When her witch boyfriend Richard starts abusing his magic, Paige organises an intervention with his family; as most of his relatives are dead due to a magical feud, she has to summon them from the afterlife.
    • On that same occasion, the Charmed ones ask one of said spirits to remain available to help them defeat a Demon; it turns out not to be necessary, as Phoebe and Paige end up becoming ghosts themselves and can solve the problem on their own.
  • The Charmed Ones occasionally organise actual séances to seek guidans or help from other spirts as well. This happens in Season 3, when they summon a dead Witch to learn about the Warlock that's targeting them, and in Season 4, when they summon a murder victim to convince the jury not to convict her innocent husband.
  • That's one of the only two methods to vanquish an evil ghost – the other being the equally unpractical pouring of a potion on their bones. On occasion, the Sisters die temporarily to invoke this trope; on another occasion, an Muggle, Martha van Lewen, commits suicide specifically to become a spirit and vanquish the ghost that's been killing her male family members (she had killed the man in the first place and therefore invokes Redemption Equals Death as well). Played straighter when Grams, who's already been a spirit for a few years, vanquishes the ghostly demon, the Necromancer.
  • There are villainous examples too: when the Triad are vanquished by the Charmed Ones, they come back as spirits to guide the Demon Dumain in stirring the Jenkins Sisters towards mutual annihilations with the Charmed Ones.
• In Kamen Rider OOO, Ankh performs a Heroic Sacrifice to enable Eiji to use Tajadol Combo one final time against the Big Bad, giving up the Medal containing his existence in the process. As Eiji fights, Ankh's spirit appears and begins assisting Eiji in the fight, even helping to fire the Finishing Move.
• Randall and Hopkirk (Deceased): The late Marty Hopkirk comes back to help his detective partner Jeff Randall, who's the only person who can see him except for the odd psychic or drunk. This help includes some limited ability to manipulate objects. In the 2000 version his abilities stretch further, including being able to possess the living for short periods of time.
• Supernatural:
  • In Season 1, Sam and Dean return to their childhood home to find it the subject of a violent haunting, and the new resident and her children in danger. Turns out the house is haunted by a poltergeist and Sam and Dean's dead mother, Mary, who assists them in the fight with the poltergeist.
  • John Winchester appears at the end of the second season, having escaped through a hellmouth and proceeds to grab and fight with Azazel. He only manages to struggle with Azazel for a few moments before he breaks free, but that still gives Dean the chance to grab the Colt and use it to finish Azazel off.
  • There is a villainous version of this in the season finale of Season 4 when Azazel slaughters a church full of nuns and uses one of the bodies to communicate with his master, Lucifer, who is trapped in Hell. Lucifer is able to give his minion a long-term plan for freeing him from his cage.
  • In Season 7, Sam and Dean's surrogate father Bobby dies, but he sticks around as a ghost for multiple episodes, helping them defeat the Leviathans before the brothers put his soul to rest. A few seasons later, Bobby helps Castiel break Metatron out of Heaven.
• The Super Sentai series shows multiple examples of this trope:
  • Kaizoku Sentai Gokaiger:
    • During the entire Legend War sequence, all previously deceased Rangers^note Besides Gai above, the list includes Dragonranger, Timefire, Shurikenger, Abarekiller, Rio and Mele. It does not include dead Rangers whose powers were already passed on, like the second Kirenger, and the first Battle Cossack and Yellow 4. As Gosei Green is inexplicably not counted among the official heroes, he's not part of this list either. are explicitly shown to have fought in it. As Gai shows, they don't quite lose their powers due to being dead. This was nearly averted in the planning stages, where only the living Rangers would be participating in the scene, before the idea was vetoed to have even the killed-off Rangers resurrected for the big battle, which has the added bonus of showing how badly every hand on deck was needed.
    • The Jetman tribute episode involves the dead Yuuki Gai/Black Condor, directly coming back from the realm of the dead to assist the Gokaigers getting the Jetman's Greater Power, before going back to the realm of the dead again.
  • Zyuden Sentai Kyoryuger
    • Ramirez is a Kyoryuger from Europe's Dark Ages, returned from the dead to grant the new team the use of his mecha, Ankydon. He even gets to morph like they do!
    • Later on, in episodes 17 and 18, we're introduced to another Spirit Kyoryuger named Tessai, a martial artist from Ancient China. Like Ramirez, he returns from the dead to support the main Kyoryugers by granting them his mecha Bunpachy, and is also able to morph when needed.
  • The finale of Ohsama Sentai King-Ohger features a pack of dead people coming back from Harkabarka, the Land of the Dead. Among them are the summer movie's Reiniol Husty and Devonica (who introduced the series to the Land of the Dead), the Dead All Along Boshimar, Action Mom Nephila Idmonarök Ne Brasieri, as well as previous rulers, Deed and Metally of Ishabana, Karras Dehaan of Gokkan, and last but not least, former abyssal king Deathnarök VIII, who turns out to be an ally^explanationMid-series episodes 24 to 26 built up the idea that Deathnarök's schemes aren't actually evil; in fact, he wanted to wreak vengeance on mankind (whose kings "sealed" the Bugnarök underground), even if it would cost him death.
• In Twin Peaks when Laura Palmer visits Agent Cooper in a dream in the beginning of the second season. She whispers the name of the killer in his ear, except he cannot remember what she said.
• In The Umbrella Academy, Ben's ghost becomes this once Kalus gets enough of a grip on his powers to not only commune with spirits, but manifest them in the physical world, too. First Ben helps Klaus stay sober, then he's able to use his Combat Tentacles to fight alongside his still living siblings. In Season 2 he's also the one able to get through to Viktor when his powers get out of control and he's on the verge of triggering the apocalypse again.
• Veronica Mars season one: the late Lilly Kane is a major motivator in the solving of her own murder. Her ghost appears to Veronica and to her brother Duncan, metaphorically. Or is it? She shows up in season two to save V's life.

• In The Gamer's Alliance, the spirits of Deidra Finian, Hiroshi Hayabusa and Megumi Nakamura assist people in the Land of the Living, providing them with a morale boost and valuable information. In Megumi's case her love allowed Hiroshi to cast Shiropyr and sacrifice himself to stop the shamanic mage Taro Ofuchi.

• Among Us:
  • Crewmates killed by the Impostor can still complete their tasks as ghosts. If all the Crewmates finish their tasks, even if some of them are dead, the Crew still wins.
  • Guardian Angels (a role exclusive to dead Crewmates) can cast a protective shield on a living Crewmate to protect them from an Impostor attack.
• In the backstory of Blasphemous, there was a girl named Tentudia whose hair grew as a succession of long thorns. While this sort of suffering would normally be seen as a sign of the Miracle's grace, she was instead denounced as a heretic and sent to a convent, only for the nuns of the convent to murder her. The Penitent One can find her scattered remains and bring them together for a proper burial; if he does so, then brings Cleofas back to Albero, he receives the prayer "Tiento to Your Thorned Hairs". While this prayer is active, if the Penitent One would take damage from anything other than a spike trap, Tentudia herself briefly appears and blocks the hit.
• Brothers: A Tale of Two Sons: After losing his older brother, Younger Brother in the final segment finds himself conquering his fear of water and a couple other tasks that he previously could only accomplish with the help of his older brother. The gameplay enforces this as you need to press Older Brother's interact button to make this happen.
• Cave Story: A maxed out Blade will invoke King's soul in ethereal form and, inflict heavy damage to whatever happens to be in the way (and around the way).
• During the Titan boss fight in Deltarune, Gerson comes back and works together with Susie and Kris to shatter its defenses in one turn and give them the idea to seal the dark fountain at its core. Notably, Ralsei explained earlier that such a resurrection probably couldn't be repeated, but Gerson came back anyway.
• Death Stranding 2: On the Beach: Neil Vana, while initially presented as a Recurring Boss from a strange realm that Sam gets periodically pulled into, turns out to be this. When he was alive, Neil pledged to protect Lou, Lucy and Sam's unborn child, but while he tragically failed and met an early demise, his spirit remained on the Earth, proving invaulable when years later, Lou and Fragile were attacked by Higgs. From this connection, Neil and his fellow Lost Souls took Lou into their Beach to keep her safe, eventually for Sam (her birth father, even if he didn't realize it at the time) to eventually pull her out to safety.
• At the end of Dishonored: Death of the Outsider, Billie learns that the Outsider's mark is actually his original, human name and returning it to him will strip him of his divinity. Unfortunately for her, only the dead can read said name, but she runs into the lingering spirit of her late mentor Daud in the Void and can persuade him to whisper the Outsider's name to him instead of straight up stabbing the Void deity dead.
• During the Darkest Hour in Dreamfall Chapters, Zoë is trapped in Storytime once again, where she meets the spirit of Crow (who has just had his neck snapped by the Prophet) on his way to the afterlife. Crow's ghost lingers long enough to help Zoë put together the puzzle of the Prophet's Evil Plan, then she manages to wake herself up, while he is approached by April's ghost (who somehow lingered in-between for over two years) and the two leave for the afterlife.
• The Elder Scrolls: After completing the main quest in Skyrim, you obtain the Call of Valor Shout, which allows you to summon one of the legendary heroes from Sovngarde for a while. And in the Dark Brotherhood questline, you get the Summon Spectral Assassin power, which summons Ensemble Dark Horse Lucien Lachance from Oblivion, who helps out in battle and gives advice on your current contract.
• In the final battle of Eternal Darkness the ghosts of all the characters who died at the hands of the darkness come back one by one to take one last swing at the Big Bad. Except Edward, he instead binds the bigger fish that Alex summoned.
• Alma from First Encounter Assault Recon, in a twisted way. In the non-canon expansion pack Extraction Point, she often wipes out incoming Replica troops and opens paths for the Point Man, for a good reason. Even better: FEAR 2, the reason being she's in love with the main character, Becket.

• Final Fantasy:
  • The Final Boss Fight of Final Fantasy IV hinges on this trope, with all the ex-party members aiding the party after the Big Bad defeated them.
  • Similarly, Final Fantasy V has the five major characters who died during the game come back and help you out against the Final Boss, though they don't help in battle.
  • At the end of Final Fantasy VII, Aerith's spirit was responsible for causing the lifestream to stop Meteor from destroying the planet.
  • Auron of Final Fantasy X does this, and has been doing it the entire game having died 10 years earlier — it's only through sheer force of will that he's not passed on.
  • Technically, Tidus also does this, as it's revealed very late in the game that Tidus & the Zanarkand he hails from are merely the cumulative dreams of a deceased people known as Fayth. It's subverted, however, as he didn't know any of the other party members (Aside from Auron) beforehand.
  • Final Fantasy XIV: During the final battle in the Return to Ivalice raid questline, the player is aided by the spirits of the Zodiac Braves against the Seraph Ultima. As Ultima is poised to overwhelm the players and the Braves, Ramza's spirit appears to even the odds.
  • During the Seat of Sacrifice boss battle in FFXIV 5.3, Elidibus banishes the player's party into the Void. Following a successful Active Time Maneuver, they call upon the aid of Emet-Selch, who was killed at the end of Shadowbringers, who rescues the party from the Void. While he appears as a generic ancient Amaurotine, his Character Tics — his Badass Finger Snap and flippant, dismissive farewell wave — out him as the Big Damn Hero.
  • During the leadup to the final dungeon of Endwalker, the Warrior of Light's allies get taken away by the Endsinger until they are left alone. Just as it seems they are doomed to fail, however, Emet-Selch returns one final time to heed the Warrior's call, alongside their mutual friend from the Unsundered world, Hythlodaeus, to rescue their friends. With the region of Ultima Thule being steeped in Dynamis, a powerful form of energy that can alter reality, Emet-Selch could've chosen to stay, but he instead elects to return to the Lifestream after helping the Warrior one last time because he didn't wish to live if it meant being brought back by the Warrior's benefactor, the goddess Hydaelyn.
• The entire point of Ghost Trick. Sissel and later Missile is the supernatural backup for his human allies.
• Guild Wars 2: Early in Living World Season 4, the Commander learns Palawa Joko is attempting to bring back the ancient (and 100% lethal) Scarab Plague. They use this news to bring the twin ghost-queens Nahlah and Dahlah into the alliance against Joko (It's Personal, their realm fell centuries before game start to the first arrival of the Plague). As the alliance moves in on Joko's castle, the lich releases the Plague ... but the scarabs that carry the disease can't attack the dead. Nahlah and Dahlah lead their ghost army against the plague-carriers, keeping them from infecting the living members of the alliance.
  Queen Nahlah: Leave it to us, mortals.
  Queen Dahlah: Find another way in. And give our regards to dear Joko. Brothers and sisters! This time WE wipe out the PLAGUE!
• When you confront the Final Boss of Jade Empire, he petrifies you with his new divine powers, boasting how no living soul can break out of that enchantment. Cue the ghost of Sagacious Zu (who died by Heroic Sacrifice earlier in the plot, but his spirit lingered due to the on-going blockage of the path to the afterlife) arriving in the nick of time to break you out and to let you continue the fight.
• A terrific example in Kingdom Hearts III; at the Keyblade Graveyard, the Demon Tide grows to absolutely titanic proportions. When Sora goes to dive into it directly, he is greeted... by Ephemer, of all people. Cue the fallen Keyblades scattered around the Graveyard rising up of their own volition, Sora mounting a Starlight in the storm for the ride, and a massive string of Situation Commands named after the players of Unchained χ[chi]/Union χ[cross].
• The Legend of Zelda: Breath of the Wild: After freeing a Divine Beast from Calamity Ganon's control, the spirit of the Champion who piloted it will set the Divine Beast in place to attack Calamity Ganon when Link goes to confront it. Each Champion also provides Link with some of their power, appearing by his side when he uses them: Mipha's Grace tops off Link's hearts (plus a little extra) when they run out, Urbosa's Fury conjures lightning in a wide area around Link, Revali's Gale creates a powerful updraft that lets Link ascend from the ground quickly on his paraglider, and Daruk's Protection creates a force field that renders Link impervious to harm.
• LISA: The Hopeful: If the player is on Beltboy's route and hasn't taken any Joy, then Lanks and Cyclops (Beltboy's fellow party members who died during the endgame) will return in spirit to help out in the first phase of the Final Boss fight.

• Shadowverse: Kyle's spirit appears to intercept an attack from Isabelle, directed at Rowen. He calms the enraged Isabelle and gives her the opportunity to reconcile with him, ultimately giving her the courage to move forward and leave her dream world.
• Shining Force: Kane in the original game, summoning a lightning strike to stop the Big Bad from possessing the main character.
• Six Ages: In Lights Going Out, you can have some of your warriors, both times with the option of having your divinely-blessed fire children Yatakan or Ayvtu leading them, ride out to join the battling gods on the Hill of Gold or accompany Elmal to fight by his side when the god visits your clan. In either case, they're gone from the game. In Lights Going Out, if a save file where this happens is imported, a random event can see them return in glory from the Gods War and join their Berenethtelli descendants, reinforcing them with fresh, experienced warriors at their bleakest hour.
• Star Fox 64: James McCloud, complete with apparent ghostly spaceship, appears at the end to guide his son out of Andross's Taking You with Me attempt.

• In the final battle of the A path in Valkyrie Profile: Covenant of the Plume, Ancel, who you have to sacrifice in the game's opening, shows up to lend a hand.
• In the World of Warcraft Expansion Pack Shadowlands, it's the reverse: the living (the Player Character and various heroes of Azeroth) help the inhabitants of the Shadowlands (the afterlife of the Warcraft universe) against the forces of the Jailer, who wants to consume every plane of existence.
• In Yakuza: Like a Dragon, summoning Daigo Dojima has him appear on the battlefield, along with the spirits of past figures from the Tojo Clan: Souhei Dojima (his father), Futoshi Shimano, Osamu Kashiwagi, and Shintaro Kazama. Together, they draw their pieces and unleash hot lead into their enemies. Kashiwagi may be a subversion, however: while he appeared to have perished in Yakuza 3, Like a Dragon very heavily hints that the propreitor of the Survive Bar is actually Kashiwagi.

• After her death in Ace Attorney, Mia Fey's job is mostly to lend moral support and helpful advice. However, when Maya is kidnapped she shuttles between possessing Pearl and Maya in order to carry messages between the two parties.
  • The absolute last contradiction in Trials and Tribulations features Mia's ghost (and not channelled spirit) briefly being visible to the final antagonist, and the player, as she and Phoenix point in unison to condemn the killer.
• At the climax of Sunrider 4: The Captain's Return, Kayto Shields tries to pull off a Spaceship Slingshot Stunt to escape from the PACT navy, but the Maray's engines aren't powerful enough to escape the gravity well of the rapidly expanding new star that it's diving towards. In desperation, Kayto prays to the ship's namesake, his deceased sister Maray, asking her to be patient because he's not going to rejoin her today. In response, Maray's spirit appears before him and supercharges the ship's Twin Drives, giving it just enough power to pull off this stunt.

• The Order of the Stick: The truth is, those paladins guarding Soon's Gate weren't there to guard the gate alone... they were there as reinforcements.
  Soon Kim: Ghost-martyrs of the Sapphire Guard, ATTACK!
• The ghost of Squeeky-Bobo from Sluggy Freelance helps out the Dimension of Pain demons now and then.

• The Weekly Roll: A variation where Torvald recruits (or rather raises) the corpses of the Velarian family's ancestors. The strip is even titled Charge of the Undeadirrim.

• Avatar: The Last Airbender:
  • Dead Avatars often come to the current Avatar's aid. Sure, to do that, it means possesing his/her body in an Unstoppable Rage, but it does help. (Usually).
  • Avatar Kyoshi does briefly take the helm of Aang's body so she could explain to the people of Chin Village that she didn't actually kill Chin. Technically.^explanationKyoshi broke her village off from it's peninsula, creating Kyoshi Island. Chin fell to his death from the then-unstable cliff, too filled with rage to realize he was no longer standing on solid, stable ground At least, something of the sort was what the heroes were hoping would happen, but her explanation amounts to “I did kill him and he had it coming.”
  • The season 1 finale also involved Aang getting some direct help from the Ocean Spirit itself when the Fire Nation finds a way to "neutralize" the Moon (and thus all waterbending). Both the Ocean and the Moon spirits crossed over to the physical world ages ago in Avatar, but they were still otherworldly in nature so it counts.
• In Bionic Six, Karate-1 would occasionally receive assistance from the spirit of his biological father.
• In G.I. Joe Cobra Commander tried using supernatural forces to call upon the restless spirits of three warriors; his first mistake was thinking he could control them. The second was summoning three who were more likely to side with the Joes' interests. (One of them was even an American World War I pilot.) Lady Jay even made light of the situation when the three spirits changed sides, saying, "I never thought we'd be getting backup from the netherworld."
• In the finale of Masters of the Universe: Revolution, Skeletor 2.0 raises an army of Techno-Titans to decimate the Heroic Warriors. But as all seems lost, the Tri-Sorceress succeeds in her ritual to recreate the destroyed Preternea. With the restored afterlife, the fallen heroes of the past descend onto the battlefield to destroy the Techno-Titans and turn the tide in He-Man's favor.
• Steven Universe: The emergence of The Cluster when it fights Yellow Diamond's ship invokes this as it's made from the shards of fallen Crystal Gems and it even takes the form of wailing ghostly shapes when it first leaves the ground.
• In the series finale of Star vs. the Forces of Evil, the past queens of Mewni manifest in assisting Star, Moon and Eclipsa in destroying the realm of magic.
• In Teenage Mutant Ninja Turtles (2003), Hamato Yoshi's spirit returns to aid the Turtles during their battle with the Demon Shredder, striking a finishing blow that cleaves the tengu in half.
• ThunderCats:
  • "The Ghost Warrior": An ancient spirit is menacing the team. It can hurt them (because of its Thundarium Mace), but they can't touch it. The Sword of Omens summons Jaga, the deceased mentor, to wield it in a ghostly battle in the sky.
  • "ThunderCats - Ho! Part V": Jaga needs to obtain a sacred item to help Lion-O. The ancient spirit once again faces him -in space!
