A small yellow fellow out to use his incredible magical powers to help those in need across the land. Just a pity that he's not very good at it.

• Ambiguously Human: Nigel is an extremely short humanoid with emoji-yellow skin and no visible nose, ears or neck. Given the vastly varied designs of the rest of the cast (to the point where it can be hard to tell who's a goblin and who's a human), it's hard to say whether "Tiny Wizards" are a Mage Species or if Nigel is a person with magical powers who also happens to be tiny.
• Angst? What Angst?: In-Universe. Nigel is often horrified by the consequences of his actions but is very quickly put back to his usual cheery demeanor by half baked assuring words from Marmalade or being distracted by something fun or tasty.
• Blue-and-Orange Morality: Nigel's drive is to help anyone in need and that means anyone. He'll help criminals who have been captured or arrested to escape and will open portals to help demons just as often as he'll help innocents and he'll help people even when it goes against his own goals. He's also not above causing trouble himself, stealing chocolate from flower people, attempting a cake heist or stealing a drunk wizard's fancy hat.
• Flat "What": Nigel's usually the more emotional and whimsical one but occasionally there's some weirdness that has him stunned into one of these, most notable of which is Garteth declaring the flower he's shouting at is pregnant.
• Hero with an F in Good: Zigzagged. Nigel is out to help people with his magic asking for no reward, but at the same time, he's terrible at it and has extremely poor judgment.
• Inept Mage: Nigel is a powerful wizard with a working knowledge of all magic types but is pretty bad at precise control, meaning he often overshoots. He's also particularly terrible at undoing his spells, once turning himself into a foot trying to undo a beard spell.
• Intelligible Unintelligible: Nigel speaks in subtitled mumbles and squeaks but is perfectly understood by everyone else. It helps that his language seems to just be distorted English - for example, whenever his subtitles read "Marmalade", you can hear him say something like "Mamaleh".
• Master of None: While definitely able to use all magic types, he's also incompetent in all of them, unfortunately.
• Nice Guy: While it doesn't always work out, Nigel's out to help everyone with his magic and has talked down demons with kind words.
• Powerful, but Incompetent: Despite his incredible magical prowess, he isn't really good at what he's capable of and tends to do more harm than good to the people he tries to help.
• Sweet Tooth: Nigel loves all sorts of sweets and snacks, and he is willing to resort to theft to get his tiny hands on them.
  Advert: Do you love chocolate so much you'd tear off your own face skin just to get some?!
  Nigel: Yes.
  Marmalade: What?
• Through His Stomach: The easiest way to distract him is dangle or even just mention junk food in front of him.
• True Companions: Nigel and Marmalade are inseparable friends and will do anything to help each other.
• Vague Age: Nigel lives independently alongside Marmalade and is apparently old enough to go to the pub (at least 18 in the creator's native Britain), but at the same time he is very naive, childish, and excitable.

Nigel's steed, friend, roommate and voice of reason, Marmalade helps Nigel in his quest to help others. Compared to the excitable and scatterbrained Nigel, Marmalade is reserved and usually the only one to notice when things have gone wrong, not that he lets it bother him.

• Cloudcuckoolander's Minder: What Marmalade lacks in magical power, he makes up for by being the sensible one in the duo, trying to rein in Nigel's worst impulses.
  Nigel: (eyes smouldering) How long are you supposed to stare at the sun each day, Marmalade?
  Marmalade: I don't think you're supposed to stare at the sun at all, Nigel.
• Fantastically Indifferent: Marmalade takes everything in stride, from a demon emerging from their kitchen floor or being merged into a bird shaped meat lump by a botched spell.
• Flat Joy / That Makes Me Feel Angry: Marmalade has only one expression and his tone of voice has little emotional variation, so he usually announces his feelings.
  I am currently wetting myself.
  I am having a panic attack.
  I have never been more excited.
• Flat "What": When things take an unexpected turn, Marmalade will often flatly ask, "What?" Played with in that, given his tone, it's hard to tell just how flat he intends it to be.
• Lies to Children: Parodied. Marmalade downplays the damage Nigel does when he's worried he's killed someone in a reassuring tones, but in the process, often spells out that he's accidentally given them a Fate Worse than Death. Not that Nigel ever picks up on that.
• Mix-and-Match Critters: Allegedly. He looks like a cuboid dog but because Nigel can ride him, he's a dog/horse.
• Only Sane Man: Downplayed, Marmalade is usually the only one to notice something is off or not right, but at the same time, he'll rarely labor on the point and quickly move on.
• Sapient Steed: Nigel can ride him, but Marmalade is the more well-spoken of the duo.
• Saying Sound Effects Out Loud: He sleeps by saying things like "Snore", "sleeping noises", etc.

A good friend of Nigel and Marmalade, Patricia's always up for a friendly chat and a drink with our heroes. She also happens to be an incredibly ruthless and remorseless criminal mastermind, but that doesn't dampen their bond.

• Affably Evil: Patricia is a genuine friend of Nigel and Marmalade and invites them around for tea and cakes. She treats nearly everyone else as obstacles or witnesses to be killed off.
• Breakout Character: Very much so. She has the most appearances of any secondary character in the series, and fans adore her murderous shenanigans.
• Brits Love Tea: Patricia loves a cup of tea and a cake, mixing a wholesome British Stereotype with other less savory stereotypes like a penchant for stealing artifacts and stabbing.
• Cartoon Creature: Patricia is a small pink quadruped with a long snout that doesn't look like any real world animal. She's identified in the series as a (psychopathic) pink blob.
• Dissonant Serenity: Her calm, grandmotherly tones never waver as she commits atrocity after atrocity.
• Foil: Patricia is a comedic foil to Nigel. Nigel is young, helpful and has immense magic but is clumsy and doesn't have his good intentions work out. Patricia is old, gleefully criminal and has no magic but has her evil schemes go off without a hitch. Despite it all, they're good friends.
• For the Evulz: While she does usually have something to gain from her crimes, she candidly admits she just plain enjoys stabbing.
• Killer Rabbit: She’s quite the dangerous being for a small creature that is described as a (psychopathic) pink blob.
• Laughably Evil: Whenever she commits a crime or murders someone, expect it to be done in the series’ usual style of Black Comedy.
• Nice, Mean, and In-Between: When she hangs out with the titular duo, she becomes the Affably Evil but sadistic Mean to Nigel's well-meaning Nice and Marmalade's flat, stonefaced In-Between
• Oop North: She has a distinct Northern accent, and embodies classic Northern stereotypes of friendliness and hospitality, as well as being extremely dangerous in a scrap.
• Psychopathic Manchild: Will murder at the drop of a hat to avoid any consequences for her actions, and defensively ask what else was she supposed to do if confronted.
• Sadist: Is endlessly amused when Nigel and Marmalade's fishing hooks get caught in the eyeballs of a sentient log.
• Serious Business: Baking, to the point where she tortures people to get their recipes and even chains up Tony Mushroom after she caught him trying to steal her recipe for Bakewell tarts. According to her, it's a cutthroat business. Also, she later kills Tony Mushroom after he insults chocolate and not because he took Nigel hostage.
• Supreme Chef: She's an excellent baker, by virtue of torturing recipes out of the finest pâtissiers in the land.
• Tom the Dark Lord: One of the most murderous characters in the show, and her name is Patricia.
• Toxic Friend Influence: When Nigel is tempted to steal the hat of a drunk wizard, she eggs him on.
• Tranquil Fury: Patricia's grandmotherly tone never wavers, even when Tony Mushroom holds Nigel at knife point, attempts to kill Nigel just to spite Patricia and insults chocolate even as she gains ominous shading and quickly kills Tony with a massive spear.
• Vocal Dissonance: Twice over. She's a small pink blob with the voice of an old English lady, and she's a vicious criminal.

• Giftedly Bad: Trim fancies himself an adventurer, but in all of his adventures, he barely got more than a few feet before having to pack it in.
• Hidden Depths: He's actually really talented at the guitar, at least by the standards of Marmalade.
• Oblivious to Hatred: Trim doesn't take notice of his now sentient boat calling him a murderous anus to his face, and tried to turn the poor thing's attempt to drag itself to the hospital into another adventure.
• Reckless Gun Usage: Trim claims each adventure starts and ends with firing the adventurer's pistol, killing two birds and nearly getting himself killed in the process.

An unnamed elderly-looking person who is the host of the fictional Show Within a Show "Cooking with Portals". They don't seem to be phased at all by any demonic occurrences that happen via the portals to the underworld they use.

• Evil Tastes Good: Considering how their recipes often use demonic portals and the food doesn't taste bad, it's safe to say that they most certainly like having their food either sourced from or cooked in the underworld.
• Mundane Utility: The whole premise of their character is using underworld portals for their various recipes.
• Nightmare Fetishist: Played for Laughs. They seem to have a liking to eating food from hell itself without being scared in the slightest at all while treating their food as if it's a regular commonplace meal they eat frequently.
• No Name Given: Unlike some of the other recurring characters, they don't have a name.

• Big Bad: Of the first full length episode, Rat City.
• Facial Horror: After getting his snout minced off by the Holy Wood Chipper, all that’s left of his mouth is a gaping hole exposing what’s left of his teeth and his tongue.
• Laser-Guided Karma: After condemning many to a horrible death via wood chipper, the Rat King ends up getting their snout ground off by the same wood chipper.
• Slasher Smile: His snout is always set in an unhinged grin, even when he’s expressing anger towards his enemies.

• Humble Goal: Gareth is looking for simple things like being a father or being accepted by his neighbours.
• Invisible Anatomy: Subverted. He appears to have no nose in spite of his large moustache but it's revealed that he just has microscopic nostrils.
• Lilliputians: Gareth is even smaller than the already tiny Nigel, being about the size of a flower in bloom.
• Mister Seahorse: After his attempt at fatherhood via preg-plant fails, Gareth asks if Nigel and Marmalade want to have a baby with him instead. Marmalade politely declines.
• Unwitting Instigator of Doom: By overdoing his wish for bigger nostrils, Gareth accidentally convinces Nostril Town the rapture is upon them, causing the town to murderously riot.

• Feathered Fiend: All the birds are rude and mouthy, with a few of Nigel and Marmalade's adventure starting with them noticing a bird laughing at someone's misfortune.
• Irony: The vulture, usual target of demonisation in fiction, is one of the few birds to not curse and its crime of attacking a zombie cyclist was purely just it following its nature of eating dead things. It even asks nicely if it can eat the cyclist's remains when he explodes.
• Mad Libs Catchphrase: "[X]! [X] bastard!"
• Toothy Bird: All birds have human teeth the full length of their beaks, to comically unsettling effect.
• Verbal Tic: Going hand in hand with their bastard catch phrase, they have a habit of calling anything and everything a bastard.

• Always Chaotic Evil: Downplayed. They all seem to be Ineffectual Sympathetic Villains.
• Designated Victim: If a hobbit shows up, something terrible's going to happen to them.
• Poke the Poodle: Their idea of crimes is lacking, with them being nuisances at worse: causing minor chaos in a grocery store, blinking their eyes right into banisters or smearing their greasy forehead over shop windows.
• Stereotype Flip: Hobbits and Halflings in fiction are typically good natured country folk or deceptively crafty thieves. The Hobbits of Nigel and Marmalade flip both depictions by being petty and inept criminals with distinct Cockney (Urban London) accents.
• Throw the Dog a Bone: Subverted, Nigel and Marmalade manage to free a Hobbit stuck in a dungeon for 16 years while making their own escape, but in the process have left him with ridiculously long arms he can't use.

These include: The Beard Shaman, The Muscle Witch, Prank Wizard, Barbara the Vegetable Witch

• Ambiguous Situation: Is the Prank Wizard an actual wizard whose gimmick is to do pranks on people, or is he just an ordinary prankster who merely dresses up like a wizard and calls himself one? Considering that he's the only wizard not shown doing any sort of magic when doing his shtick, it may or may not be the latter.
• Creepy Good: The Beard Shaman uses the powers of the underworld but helps Nigel undo his foot transformation and find his true facial hair.
• Master of One Magic: Unlike Nigel who has a wide variety of spells he's not great at, other wizards seem to specialise in one particular magic and can help Nigel undo his botched spells.
• Mundane Utility: The Hot Chocolate Wizard opens up portals to the underworld in order to steal hot chocolate from demons.
• Secret Art: The art of Muscle Magic has been made illegal, so the Muscle Witch instead runs a gym, but is more than willing to offer it on the side under the counter.

• Face–Heel Turn: The talking boat that Nigel and Marmalade crown pirate king very quickly goes mad with power and tries to have them and Patricia executed for getting him hurt in the first place.
• Sentient Vehicle: Talking Boats are sentient water craft that can sail themselves but can be prone to freezing in fear or going on strike if they feel unappreciated.
• What Measure Is a Non-Human?: Kredrick Spurtus's declaration that he should "give up and sink this big top boat". The boat is a little surprised at how offhanded Kredrick sounds about sinking him.
