This character sheet includes the major characters in the Earthworm Jim franchise. Because the animated series portrayed some characters in a very different fashion to the games, and the two comic book series even moreso, appropriate character sheets will divide their profiles between a Games version, a Cartoon version, and a pair of Comics versions.

Heroes
Earthworm Jim
Cartoon: As in the game, Jim was created when Psycrow lost the Super Suit and it landed on a Texan earthworm. Unlike the game, Jim instead set out to become a superhero, for reasons unknown. Flamboyant, naive, simple-minded and at least a little crazy, Jim is nevertheless one of the best heroes in the known universe. Voiced by Dan Castellaneta.
1995 Comic: Similarly to the game, Jim was created when Psycrow lost the Super Suit and it landed in a Texan farm's field. Unlike in the game, this version of Jim was an intelligent mutant earthworm even before the suit landed; it was his ability to read the manual that allowed him to take the suit and use it to become a superhero. His first mission was the rescue of Princes Whats-Her-Name, and after that, he becomes generally devoted to opposing the machinations of Queen Slug-For-A-Butt and her cronies.
2019 Comic: Like the game, Jim is created when a Super Suit lands in Texas and a normal earthworm crawls inside. This time around, he is also affected by the magic of a mysterious space fairy. This version is easily the most naive and inexperienced, but still has a good heart, sees the beauty in the world, and is willing to attempt to be a hero despite the risks.
- All Men Are Perverts: In the cartoon. One of his only four brain cells is always occupied with finding where the girls are hiding.(Finding a huge cake) "Hey! Nice cake! Is a girl gonna jump out?"
- Appropriated Appellation: 2019 Comic only. The first person he meets upon creation is a farmer who introduces himself as "Jim. Farmer Jim". So our hero borrows the idea and decides to be "Jim! Earthworm Jim!".
- Arch-Enemy: Psycrow has shades of being this to Jim in all the continuities, since he's a crow and Jim's a worm, but he's most explicitly this in the 1995 comic, where he ate Jim's friends and family.
- BFG: Subverted. Jim's primary gun is a small handheld ray-gun. It still packs a massive amount of firepower, and it's a rapid-fire weapon.
- In the second game, Jim gets the Barn Burner, a Smart Bomb weapon so big that he literally struggles to lift it.
- Breakout Character/Guest Fighter: Jim is the only character that appears in other games than this series, mostly in Fighting Games:
- First as a Secret Character for PC version of Battle Arena Toshinden, which also was distributed by Playmates Interactive, in which he was just a Moveset Clone of Rungo.
- But his most famous appearance outside his game series is in ClayFighter 63 1/3 and its sequel Sculptor's Cut (again as Secret Character) for Nintendo 64. In both games, Jim is on vacation after his adventures and came to Klaymodo Island, where he joined the other heroes to stop Dr. Kiln from converting the world into clay. He also has Boogerman as The Rival for these games (mostly in the first one, in Sculptor's Cut he has Ickybod Clay as his Rival Final Boss). In both games, his voice actor is Dan Castellaneta as in the TV series.
- Brought Down to Normal: Relatively speaking, to the extent that a hyper-evolved worm in a super-suit can be: Jim once had his super-suit replaced with one that gave him the strength of a normal person. A normal, really big person, as Professor Monkey-for-a-Head found out the hard way.
- Bunny-Ears Lawyer: Jim may be an idiot, but he's still a very capable crime fighter. This is especially shown in Egg Beater where Jim manages to fight most of his Rogues Gallery at the same time and come out victorious.
- Butt-Monkey: Jim's a big childish loser and we love him for it.
- Catchphrase: "Groovy!" (extended to "Guh-roovy!" in the cartoon)
- "WHOOOA, NELLIE!!!"
- "EAT DIRT, [disparaging description of enemy]! AH-HAHAHAHAHAHAHAHAHA!"
- "By the Great Worm Spirit" (et cetera...)
- In Season 2: "Don't question me..."
- Also: "Get off my back, man!"
- And don't forget the ones from ClayFighter 63 1/3:
- "I'm a superhero!"
- "Eat Cow!"
- "Tumbleworm!"
- "Earthwormmm Jimmmm!", said it as Mr. Kennedy.
- Clothes Make the Superman: Jim is only sentient because of the energy from his suit mutating him from being an ordinary annelid. Although the boost to size and intellect is permanent, all of his strength, firepower and physical abilities are due to his suit.
- Detachment Combat: Can do this in the cartoon, though he doesn't use this function very often.
- Genius Ditz: Jim in the 1995 comic is a weirdo who can sometimes do rather stupid things, but in combat, he's incredibly skilled and capable. Even without his Super Suit, he outwits, evades and ultimately takes down Psycrow and Professor Monkey-For-A-Head with ease.
- Heroic Comedic Sociopath: Jim's plan B boils down to "blast away randomly at any viable target while laughing maniacally".Jim: Oooo-kay. When all else fails... START BLASTING!!! AH-HAHAHAHAHAHA!!! (shooting at a black hole) EAT DIRT, INSUFFERABLE SPACE ANOMALY!!!
- Heroic Sacrifice: In "The Anti-Fish", Jim baits the universe-destroying horror into eating him so that he can pull out a Taking You with Me by activating the self-destruct mechanism on his suit, blowing himself up along with the horror for the safety of the universe. He gets better afterward with help from the Great Worm Spirit he and his friends had saved earlier.
- Idiot Hero: Jim in the cartoon zigzags between this, occasionally coming up with some clever ideas to defeat his enemies, but generally being rather dense.
- Large Ham: Lives this in the cartoon.
- "L" Is for "Dyslexia": One of the questions in "The Villi People" asks if Jim is dyslexic. The correct answer is "Sey".
- Powered Armor: The Super Suit, natch. In the games, it runs on atomic power; in the cartoon, it runs off a "Battery of the Gods". Unusually for the trope, it doesn't possess built-in flight systems; rather, Jim utilizes his Pocket Rocket.
- Psychopathic Manchild: In the cartoons, Jim's interests include watching a kid's show ("The Mr. Bunnybutt Show"), reading a funny animals popup book, firing his gun at anything that catches his attention, and pummeling people senseless.
- Religious Bruiser: In the cartoon, Jim often prays to his god, the Great Worm Spirit and eventually gets to meet him.
- Screams Like a Little Girl: You can definitely hear Dan Castellaneta channel Homer Simpson when he screams.
- Small Name, Big Ego: The cartoon zigzags on this. Jim is crazy, egotistical and full of himself, but, more often than not, when the chips are down, he proves himself to be genuinely competent (especially in comparison to most of the other "heroes" in his universe).
- Trademark Favorite Food: Jim's favorite food is apparently chip butties note , as they appear as mega-healing powerups in the second game.
Peter Puppy
Cartoon: Once an ordinary dog mocked by his fellow canines for being small and cowardly, Peter dared to break the Great Taboo of the Dogs — approaching a running vacuum cleaner — in an effort to prove himself. But vacuum cleaners are canine-specific trans-dimensional portals, and Peter was sucked through a wormhole to the Planet Heck, where Evil the Cat set a demonic spirit on Peter that transformed him into an anthropomorphic dog — who also happened to turn into a monster when hurt, scared or enraged. Banished back to Earth, Peter was outcast as a freak, until he stumbled into the path of Earthworm Jim. After a rather hostile first meeting, Jim warmed up to his "fellow freak of nature" and eagerly took Peter on as his sidekick. Voiced by Jeff Bennett.
1995 Comic: A humanoid canine-like alien from the highly dangerous Dogstar System, Peter was abducted by Professor Monkey-For-A-Head, who began subjecting him to experiments to turn him into a living weapon. Although Jim freed him before the Professor could complete his project, the experiments left Peter with an uncontrollable ability to shapeshift into a monstrous alter-ego.
2019 Comic: Here, Peter is actually 'Proto Pooch', an organism sent (and presumably created) by Slug-For-A-Butt to Earth to act as an advanced scout and spy. Jim's friendship convinces him to switch sides.
- Adaptational Dye-Job: Changed from light purple to cream coloured for the cartoon series.
- Adaptational Modesty: He wears clothes in the animated series, when his counterpart in the original video game went naked.
- Adaptational Species Change: From an alien in the games and 1995 comic, to a magically cursed Earth dog in the cartoon, to some kind of alien being that happens to look like a dog (specifically, a Jack Russel/Beagle mix) in the 2019 comic.
- Ascended Extra: From the subject of an Escort Mission in the first game to Jim's primary sidekick and righthand man.
- Badass Adorable: A terrifying monster when he's angry, an endearing cartoon animal the rest of the day. Yep, seems to fit the bill all right.
- Barefoot Cartoon Animal: In the cartoon, at least, where he sports a shirt and shorts, but no shoes. In the games, he's completely naked. The difference between the two versions is lampshaded in the 1995 comic, where he has the cartoon's outfit and mocks the games for featuring him naked.
- Berserk Button: Fear, pain, anger and Jim's constant stupidity. The first three invariably result in a Hulk Out.
- Inverted slightly as Peter himself expresses in the first episode he has no control over his Berserk Button induced alter ego and spends most of it trying to apologize vigorously for brutally attacking Jim earlier on.
- Beware the Nice Ones: BIG TIME.
- Big Ball of Violence: Whenever Jim fights Peter's Monster form.
- Blessed with Suck: The spirit possessing him grants him intelligence and anthromophism, at the cost of going One-Winged Angel if anything pisses off, hurts, or scares him. One episode has him cured of this, but he gains it back in order to save Jim's life.
- Brought Down to Normal: In "The Origin Of Peter Puppy" when Jim tries to cure Peter's transformations by disposing of the demonic spirit possessing him. The spirit was unfortunately also the source of his intelligence and anthropomorphism, and its exorcism turned him back into a normal non-anthro dog.
- Butt-Monkey: In the cartoon. He suffers a bit in the games too, though dishes out the abuse more often.
- Catchphrase: His Madness Mantra for when things get really bad: "I must not fear, fear is the mind killer, fear is the little death that brings total oblivion."
- Dragged into Drag: Happens often in the cartoons, such as when he's dragged into a skimpy bikini and a flower girl's dress.
- Explosive Breeder: By the time of Earthworm Jim 2, Peter is the father of 600 children.
- Half-Dressed Cartoon Animal: Cartoon only (he is completely naked in the games), this is yet another result of being possessed by the demonic spirit. Peter considers it one of the better perks.
- Hulking Out: Peter is a good guy, but if he gets scared or hurt, his monstrous alter ego takes it out on whoever is in the vicinity, usually Jim.
- Invincible Villain: In the games, you cannot avoid or fight back against Peter if he hulks out, just prevent it or expect a maiming. The cartoons justify this as he is Jim's best friend. During their first meeting, Jim actually very easily neutralised him.
- Kid Sidekick: In the cartoon.
- Killer Rabbit: Peter looks harmless and fluffy... right up until he gets scared or injured and turns into a monster.
- The Millstone: His Hulking Out form will nearly always attack Jim and only Jim. In the first episode of the cartoon, Jim actually loses patience with Peter after another transformation earns Jim a mauling, while the bad guy gets away scot free.
- Misplaced Retribution: Whoever or whatever sets off his demonic transformation, Jim is nearly always its first target (though sometimes, Jim will do something to cause it, mostly by accident or his own stupidity). Justified in the cartoons, as Peter himself explains he has no control over himself when it happens, and is usually rather embarrassed or ashamed of it. Although, when he turns into a monster in "Bring Me the Head of Earthworm Jim", he looks genuinely confused over whether to attack Jim or Psy-Crow (who is wearing the Space Suit while Jim was left with a powerless copy). It might be the suit rather than Jim himself that draws him to attack, as he ultimately decides to attack Psy-Crow.
- Only Sane Man: Shares this role with Princess What's-Her-Name in the cartoon.
- Running Gag: Smells and/or eats something delicious until he learns it's actually haggis and reminded what it's made of. Occurs at least once per episode.
- Servile Snarker: In the cartoon, he can switch between being a naive follower of Jim or a neurotic commentator to his bumbling from scene to scene.
- Superpowered Evil Side: Peter's transformation is extremely strong and dangerous... and also a mindless berserker that attacks anything nearby, usually Jim. It's even caused by Demonic Possession in the cartoon.
- Undying Loyalty: No matter how intelligent he is, Peter is still, you know, a dog and thus he'll never leave Jim's side no matter how much he might irritate him.
- Vitriolic Best Buds: With Jim in the cartoon; between Jim's antics and Peter's uncontrollable transformations, there is the odd tension to say the least, but Peter certainly hates being taken from Jim's side.Peter: *banging his head on the table, sobbing* I WANNA BE JIM'S SIDEKICK AGAIN!!! I WANNA BE JIM'S SIDEKICK AGAIN!!!
- Why Did It Have to Be Snakes?: Ever since he learned the ingredients of haggis, it's been his worst personal nightmare.
- Also vacuum cleaners, according to "The Wizard of Ooze".
Princess What's-Her-Name
1995 Comic: For the most part, this What's-Her-Name resembles her game counterpart, but she also has the strength, fighting skills and confidence of her cartoon counterpart. The result is an odd blend of sweet, somewhat clueless girl and a fearlessly capable warrior.
Cartoon: Born hideously deformed by the standards of Insecticans, the Princess suffered countless humiliations at the hands of her malevolent sister, who refused to even allow her to have a name and banished her to the dungeons. Vowing to defeat and overthrow her sibling, the Princess trained throughout her childhood, growing up into a mighty warrior. While Earthworm Jim's insistence that they are a couple irritates her, she does consider him a good friend and appreciates his help in her efforts to try and defeat the Queen. Voiced by Kath Soucie.
2019 Comic: This incarnation is actually an Earth woman who was kidnapped by Slug-For-A-Butt at some point and raised as her daughter. She disagrees with her mother's methods of planetary destruction and steals the Super Suit, allowing it to eventually make its way to Earth. She is far more level headed than Jim, and although not as much of a warrior as in the cartoon, is still the driving force of the group in their quest to defeat her adopted mother.
- Action Girl: In the cartoon, she's the leader of a ragtag band of rebels and has basically been trying to overthrow her sister since she was a little girl.
- Adaptational Intelligence: A Brainless Beauty in the games, but definitely a brainy beauty in the cartoon.
- Adaptational Modesty: She wears a yellow top over her regular outfit in the cartoon.
- Beauty Equals Goodness: Played straight and inverted in parody. By human standards she's supermodel level hot. By the standards of her own species she's hideously deformed. The narrator even lampshades this.
- Brainless Beauty: In the games, according to her character profile in the manual. Subverted in the cartoon and the comics. Amusingly, her evil clone created by Evil Jim has this personality in the cartoon.
- Butt-Monkey: Despite establishing her as far more competent than Jim, the cartoon's version has multiple examples of her suffering Amusing Injuries or otherwise suffering mishaps (one notable example being a flying duel against her villainous counterpart in Evil Jim's team having What's-Her-Name seemingly victorious only for her to end it getting sucked into an airliner's engine then sent falling way down until literally crashing right on her head).
- Cute Monster Girl: While an Insectican like Queen Slug-for-a-Butt, she's basically a beautiful woman with long red hair, cute little wings, and a pair of antennae. In a subversion, her own species considers her hideously malformed.
- Whereas the Queen is modeled after termite queens, the Princess (at least coloration-wise) appears to be modeled on wasps, and indeed has a wasp waist
.
- Whereas the Queen is modeled after termite queens, the Princess (at least coloration-wise) appears to be modeled on wasps, and indeed has a wasp waist
- Damsel in Distress: In the games. Subverted in the cartoon.
- Girly Bruiser: Her 1995 comic incarnation is largely a sweet, fashion-loving Girly Girl... but she's also a super-strong warrior who eagerly leaps into the fray when violence is imminent.
- Green-Skinned Space Babe: The insect wings, dainty antennae, and slightly too big eyes are the only indicators that the Princess is an alien and not a human woman.
- His Name Really Is "Barkeep": Her real name is indeed "What's-Her-Name" according to the manual of the second game.
- Human Aliens: Insecticans are normally disgusting bug creatures, but Whats-Her-Face is horrifically disfigured (at least by her species' standards) in such a way that she looks like a beautiful human woman. The 2019 comic averts this as there is a beautiful human woman who was abducted and raised by the Insecticans.
- Humans Are Ugly: An odd non-human example (well in the games and cartoon anyway). The Princess despite being insectian looks like an attractive human woman, yet is considered as ugly to her own people as her sister is seen as to humans.
- Impossible Hourglass Figure: The black-and-yellow stripes on her leggings further prove that she has a wasp waist.
- Interspecies Adoption: In the comics, she's the adopted daughter of Queen Slug-for-a-Butt.
- Ms. Fanservice: She's quite a curvy one.
- Non-Mammalian Hair: She sports a red ponytail that reaches her ankles, and she's an Insectian.
- Non-Mammal Mammaries: Once again. She's an alien bug woman. She has no reason to have these and therefore its a sign of her deformity to her people who likely see them as tumours.
- Averted in the comics, where she's human, merely one adopted by Queen Slug-for-a-Butt.
- Oblivious to Love: The cartoon version of the Princess has no clue about Jim's romantic obsession with her, insists that his elaborate romantic evenings are not a date, and practically makes a Catchphrase out of her denial.
- The Princess: What do you mean, 'relationship'?''
- She's shown as rather receptive towards Evil Jim's charms (with Evil Jim in manys being a Jim with his worst traits traded out). One can say then that in the cartoon's universe What's-Her-Name knows well about romance and therefore she's really rejecting Jim since she's just not into him.
- Averted in the 1995 comic, where she is just as interested in Jim, and Bob is even able to coerce her into marrying him by threatening Jim's life.
- Super-Strength: In the 1995 comic and the cartoon, she boasts that, as an Insectican, she has the strength of 100 men.
- Princess What's-Her-Name: Or a hundred man sized crows.
- Women Are Wiser: In the cartoon and both comic continuities, her comedic flaws and quirks are far more limited than the rest of the heroes, or most of the cast altogether (it is a nineties cartoon).
Snott
- Blob Monster: He's a glob of green ooze.
- Canon Immigrant: Though
Word of God is that he was the slimy platforms that Jim battled the Queen on in the final level, for most people, he only appeared in the cartoons and was then brought to the games in Earthworm Jim 2. - Chuck Cunningham Syndrome: He completely disappears from the cartoon after the first season.
- Eloquent in My Native Tongue: To Jim and Peter, who can understand him, Snott can say a lot of things with only a few gibbers.
- Small Role, Big Impact: For the first game. He doesn't show up till the end (though apparently he hitched a ride in Jim's backpack on the Phlegm Planet), yet he serves as a platform in Queen Slug-For-A-Butt's otherwise spike-laden lair. Without him, Jim wouldn't have a safe place to stand while fighting her.
- Team Pet: His basic role in the cartoons seems to be this.
- The Unintelligible: Snott speaks a language of slurps, gurgles and burbles.
Villains
Psycrow
Cartoon: A nefarious space villain, Psycrow roams the galaxy in search of plunder and excitement. Conquest, destruction, thievery, these are all part of a day's work for a Scourge of the Spaceways. He's not above hiring himself out as a mercenary or assassin, but he's quite comfortable working for himself. Voiced by Jim Cummings (1952).
Comics: About the same as the games, although he apparently possesses the ability to convene with the spirits of dead Earth crows in the 2019 comic, and he ate Jim's friends and family in the 1995 comics.
- Abnormal Ammo: In the games, Psycrow's primary weapon is a gun that fires giant fish hooks. Of course, fish hooks are often used with worms as bait, so it’s no wonder that it can hurt Jim.
- Arch-Enemy: Queen Slug-For-A-Butt may be the Big Bad, but Psycrow is Jim's primary foe in the games and often the cartoon, and with good reason. Not only is he a crow (and crows eat worms), but his weapon is something many earthworms meet gruesome ends impaled on. He is like an amalgamation of earthworm nightmares.
- Bounty Hunter: But of course. His work (un)ethic is that the more profit the better.
- Butt-Monkey: Downplayed in the Launch The Cow graphic novel - while he's still a dangerous adversary, he gets put through a number of misadventures while chasing the lost Super Suit, including getting pummeled (and wedgied) by a bar of angry bikers and trampled by a bull (though he's seen vaporizing the latter in revenge).
- Card-Carrying Villain: While nearly all of the Rogues Gallery display this trait in the cartoon, Psycrow seems to have the most devout professional life regarding it, with several of his intervals being mock-commercials for villainous societies or victims of superheroism.
- Creepy Crows: Ok, he's not that creepy, but he is villainous and his presence is bad news for our earthworm hero.
- Deadpan Snarker: In the cartoon, he typically has a deadpan reaction to the insanity going on around him and often snarks at Jim or Professor Monkey-For-A-Head.
- Determinator: Psycrow doesn't give up easily.
- The Ditz: Quite frequently in the cartoon, most notably when Jim and Peter fly into his head through his ear canal in the Book Of Doom episode and find out that it's every bit as microscopic as they are.
- The Dragon: To Queen Slug-For-A-Butt on frequent occasions whom he sees as a profitable employer rather than as a master.
- Upgraded to full-on Big Bad in the second game.
- Fat Bastard: Despite being a Bounty Hunter he is a bit out of shape if his pot belly is any indication.
- Feathered Fiend: No wonder he is Jim's arch-nemesis - crows (just like many other birds) are known for eating worms.
- The Heavy: He is the antagonist most directly affiliated with the whole super-suit plot, as the BigBad's main agent and enforcer. That's why the plot of the whole game is one big chase between him and Jim, with every other enemy acting as an intermission to this.
- In Space, Everyone Can See Your Face: His fishbowl-like helmet is perfectly transparent.
- Punny Name: He's a villain whose name is a play on "Psycho" and crow and while not particularly he is a sociopathic killer.
- Recurring Boss: In the first game since the whole plot is a race between him and Jim.
- Skippable Boss: The player only has to fight him if they lose the "Andy Asteroids" race.
- Signature Laugh: An odd "Eh eh eh!" cackle.
- Spell My Name With An S: Is it Psycrow or Psy-Crow?
- The Vietnam Vet: In the cartoon, the Great Worm Spirit saved his life in the 'Nam, man.
- Would Hurt a Child: Where other people may see cute little puppies that need tender care and affection, he sees perfect projectiles that can go splat and inconvenience his nemesis Jim.
Evil the Cat
Cartoon: Depraved ruler of Planet Heck, the source of all true evil, this mad feline yearns to destroy the universe. Voiced by Edward Hibbert.
1995 Comic: Identical to his game counterpart, Evil is a minor character in this mini-series, having been hired by Queen Slug-For-A-Butt, Major Mucus and Doc Duodenum to capture Earthworm Jim with his army of demonic lawyers. Unfortunately, they just can't seem to catch up to the earthworm...
2019 Comic: Not as independent this time, and apparently an explicit minion of the Queen. Still says "A minor setback" though, and now touts Communist ideals.
- BFG: Never one to do things the simple way, he attacks Jim with an enormous gun that shoots fireballs.
- Born Unlucky: In the cartoon, Evil is perhaps more prone to Amusing Injuries than anyone else because of his own carelessness towards his environment, usually has his plans thwarted by circumstances beyond his control, and can't even keep romantic interests.
- Card-Carrying Villain: What would you expect from a cat who is the embodiment of pure evil?
- Cartoon Creature: He looks more like a rat with pointed ears.
- Cartoony Tail: He has a naked tail like a rat.
- Catchphrase: "A minor setback".
- Cats Are Mean: The core precept behind Evil the Cat. Although an Unsympathetic Comedy Protagonist in the cartoon.
- Cats Have Nine Lives: You need to kill Evil nine times in the video game for him to finally bite the dust for good. Apparently even that's only temporary given that he returns in the sequel anyways.
- Didn't Think This Through: In the cartoon, when questioned, by his own dumb thug no less, on what he plans to do in the aftermath of succeeding in destroying the entire universe, he admits he had never really thought about it. Doesn't stop him, though.
- Even Evil Has Loved Ones: He unexpectedly developed feelings for both a cat that he saw on TV and for his soulmate Malice the Dog and doesn't seem to realise the paradox of hating anything good and yet having good feelings for another being. Heck, he isn't willing to admit that its love, despite his choice of words making it obvious.
- Furry Reminder: In the first game, he'll occasionally stop and clean himself like a normal cat would.
- Generic Doomsday Villain: Parodied. Evil wants to destroy the universe simply because it's on his to-do list. It's also abundantly clear that Evil doesn't understand the consequences of his goal.
- Glowing Eyes of Doom: He has glowing yellow eyes. During the second phase of his battle, this becomes crucial to spot him when he tries to pounce you.
- Omnicidal Maniac: His cartoon version is obsessed with destroying the universe.
- Planet Heck: Rules the Trope Namer.
- Playing with Fire: Fire is his primary means of attack, be it the fireballs shot by his BFG or just fire waves from nowhere.
- Satan: In the games and the 1995 comic, he is basically this. The cartoon version is much the same, but played as far more of a comedic loser.
- Swallowed Whole: Is swallowed whole by Monster Peter in the finale of the 1995 comic. He's unphased by the whole affair, although not looking forward to needing to use the toilet system to make his way back to Planet Heck.
- Tactical Suicide Boss: Overlapping with Boss-Arena Idiocy. His own fireball gun destroys the platform he is perched on and allows Jim to recover his stolen suit. It fits with his careless behaviour.
- Unholy Matrimony: With Malice the Dog. They hit it off rather well, until Malice left him to star in her own show in a different universe.
- Wicked Cultured: In the cartoons, he has the most hellish and destructively evil ambitions of the Rogues Gallery, spaced in between the odd movie night and romantic affair of course.Evil: I'm just watching TV.
- Would Hurt a Child: Upon learning that a little boy was the living embodiment of kindness and purity of heart, he became obsessed with destroying him exactly because of those qualities rather than in spite of them.
Bob the Killer Goldfish (and #4)
Cartoon: Fundamentally identical to the games, Bob in the cartoon series is depicted with a bombastic, evangelical personality. The planet is also given the name La Planeta de Agua (¡arriba!). Voiced by Jim Cummings (1952).
1995 Comic: Basically a retread of the games, although the planet's name is retained from the cartoon.
- Animal Jingoism: Averted. Despite the fact that housecats are known to eat goldfish, Bob has a far better relationship with #4 than you’d expect. He also employs smaller cats in the first game that will engage in Metronomic Man Mashing if Jim gets too close.
- Brains Evil, Brawn Good: Exaggerated and played for laughs. His relationship with Jim is a classic example of a powerful hero facing off against a physically weak villainous mastermind. His level is among the hardest in the whole game, yet Bob himself is so physically weak that Jim can defeat him just by walking into him and toppling his bowl over.
- The Brute: #4. In the games, he can't be fought, only avoided — touch him and he'll send you flying.
- Dumb Muscle: #4 is so dimwitted, he can be tricked to chasing a clockwork mouse that's been tied to his tail... but is strong enough that even Jim fears getting into melee with him.
- Even Evil Has Loved Ones: In the cartoon, he briefly speaks lovingly of #4's three predecessors (all of whom had passed on).
- Evilutionary Biologist: The episode "Darwin's Nightmare" revolves around Bob trying to "evolve" himself into a higher lifeform, recognizing that his fishy body is a physical limitation in his particular line of work.
- Comes complete with Evolutionary Levels; Bob goes from a goldfish to a giant lungfish to a T-rex to a human to a human with a giant skull-piercing brain, super-intelligence & psychic powers and finally ends up a goldfish again.
- Genius Cripple: Bob is a scientific and architectural genius, handicapped by the fact that... well, he's a tiny little fish with no limbs. He's dependent entirely on the hands of his dimwitted feline minions.
- Gone Horribly Right: In the cartoons, Bob's plans often turn up like this.
- Show fish how to "destroy, destroy, destroy"? One of them attacks him in the same manner.
- Awaken the Anti-Fish? It not only refuses to obey him, but sets off to destroy the entire universe by eating the Great Worm Spirit, forcing Bob into an Enemy Mine situation with Jim if he wants to be able to conquer the universe.
- Mutate the entire fish population of La Planeta de Agua (¡arriba!) to have super intelligence? They realize he is a dangerous megalomaniac who must be obliterated and turn on him.
- Use a special gadget to steal evolutionary energy? Eventually absorb too much, turning Bob from a powerful psychic menace back to a helpless goldfish.
- Gratuitous Spanish: The cartoon name for Bob's world translates to "The Water Planet" or "The Planet of Water", and is always followed in show by a Mexican yell (usually written as "¡Arriba!").
- Harmless Villain: One of his most defining traits is how hilariously ineffective he is.
- In the first game his level is grueling and his minions are formidable fighters, but Bob himself is the poster child for the Zero-Effort Boss. In the second game he gets a downgrade to being the master of the first and easiest level, where he once again is a pushover, this time being killed in a cutscene. He puts up more of a fight in 3D, but keeping in line with his ineffectiveness he is the easiest boss in the game.
- The cartoon plays with this; though capable of being a major threat on occasion, he is still easily the most problem prone and most pathetic of Jim’s villains. Furthermore his failures are often his own fault instead being foiled by Jim’s strength or wit.
- Interspecies Romance: His role in the 1995 comic is similar to that of Psycrow's in the second game; he has Psycrow and Professor Monkey-For-A-Head attack Earthworm Jim and Princess What's-Her-Name to abduct the latter so he can force her into marrying him.
- Irony: In the cartoon, Bob's accent and mannerisms are a blatant Shout-Out to a Dixie televangelist, yet he is actually a hardcore scientist and easily comparable to Professor Monkey-for-a-Head in his genius.
- Mobile Fishbowl: He's a regular goldfish in a bowl who gets carried around by a musclebound cat minion. Hilariously, in "The Anti-Fish", he still uses this method of transport when he's already underwater.
- Politically Incorrect Villain: Played for laughs in the 1995 comic, where Bob repeatedly belittles and dismisses Princess What's-Her-Name due to her gender. When he learns she's beating up all of his minions after being abducted, he's amazed that his forces could be thwarted by a "mere girl", despite knowing that she's an Insectikette, whose species has the strength of 100 men.
- Silent Antagonist: #4 and, in the games, Bob.
- Tom the Dark Lord: The most evil conqueror and destroyer fish in the universe is named Bob.
- Weak Boss, Strong Underlings: Bob himself is not very threatening and is a Zero-Effort Boss both times he shows up. #4 on the other hand packs quite the punch, literally as one punch deals quite a bit of damage to Jim.
- Zero-Effort Boss: In both games. In Down the Tubes, you just need to tip over his fishbowl. In Anything but Tangerines, Jim simply plucks him out of his fishbowl and eats him. Justified in that, despite his intelligence, he’s still ultimately just a goldfish- would you expect him to do anything in a fight against Jim?
Professor Monkey-For-A-Head
Cartoon: A freelanced evil scientist, the Professor claims he was once a simple dairy farmer before he grafted a monkey to his head and became the most notorious of evil geniuses in the galaxy. Creator of the Super Suit, he can build another one whenever he wants with no problems — but the suit requires a Battery of the Gods to function, and he only had the one. When he tried to get another, he was turned into a human breadmaker and can, by focusing, produce warm fresh bread from inside his clothes. He notes this is actually kind of handy, as twisting the monkey's tail lets him make pumpernickel. Voiced by Charlie Adler.
1995 Comic: He's fundamentally a reprise of his original game self. The most notable change is his role as the creator of Monster Peter. He first appears as a hired lackey working alongside Psycrow at the behest of Bob the Killer Goldfish.
2019 Comic: Same as the games, more or less—a minion of the Queen who makes the super suit for her. No mention has been made of why the current suit is the only one that works, however. Also, the monkey throws its own poo this time around.
- Berserk Button: In the cartoon, the Professor hates fruit carts because one (somehow) killed his father. The manual for the first game mentions that calling him "Monkey Professor-For-A-Head" is a good way to make him angry. (That's apparently not the case in the cartoon).
- Body Horror: It's Played for Laughs, of course, but still - the guy has a monkey surgically grafted to his head!
- Does This Remind You of Anything?: In the cartoon, the Professor admits the monkey is in fact a chimpanzee who glued the tail on because he feels like he's a monkey trapped in an ape's body.
- Domestic Abuse: In the cartoon, the relationship between the professor and the monkey isn't exactly wine and roses. The monkey has accused the professor of "making eyes at a gorilla" (to which the professor angrily retorted he's a happily grafted man), viciously beaten him with a steel rod during a psycho-therapy session, and deliberately put shrinking cream in the professor's coffee so it can watch shows the professor hates.
- From Nobody to Nightmare: In the cartoon, it's claimed he was once nothing more than a simple dairy farmer. Now, he's such a space villain he has even been featured on Lifestyles Of the Rich & Villainous, with such creations as the Sparktronic Protobluntifier, the Atomic Banana, the Pay Toilet, and, of course, the creation of the Super Suit.
- Mad Scientist: You don't get much madder than attaching a monkey to your own head.
- Multiple-Choice Past: The reason for his, um, "condition" varies based on the medium. The games don't offer any kind of origin outside the (arguably canon) N64 game, which implies it's hereditary (as seen by his late great aunt Baroness Beaver-For-A-Head). The cartoon doesn't offer any origin either, although it's apparently such a common occurrence that there are self-help groups for it. As for the comic, this is done on purpose; TenNapel has stated that he has no idea why the Professor is the way he is and has no intention of ever deciding on it any time soon.
- Multiple Head Case: Technically inverted, the Professor and the Monkey are more like two bodies sharing a head. But the two have separate brains, so there can still be dissension between them - such as the monkey eating the Prof's super suit plans.
- No Plans, No Prototype, No Backup: Subverted. In the games, the professor had blueprints but the monkey ate them. In the cartoon, he can rebuild the suit whenever he wants, he just can't make it as powerful as the one Jim has without another Battery of the Gods.
- Straw Character - Scientist: According to his blog, the creationist Doug TenNapel created Professor Monkey-for-a-Head as a Take That! to his Darwinist high school science teachers. The cartoon transferred this trait to Bob.
Queen Pulsating Bloated Festering Sweaty Pus-Filled Malformed Slug-for-a-Butt
- Archnemesis Mom: In the graphic novel Launch the Cow, she's retconned to be the mother to Princess What's-Her-Name. Their antagonistic relationship, however, remains pretty much the same.
- Ass Kicks You: Her formidable backside is an enemy in and of itself, and must be fought into submission to reach her body. And even after the projectile-shooting slug-like tip of her butt is beaten, Jim still needs to deal with repugnant secretions dripping down from the rest of it.
- Authority Equals Asskicking: She is the queen of Insectika, and both ends of her body can kill you. She is even more powerful while wearing the Super Suit.
- Beauty Is Bad: A variation. By the standards of her people, the queen is considered incredibly attractive. yet rules her planet like a tyrant. Therefore, if Insecticans are the ones who're playing the game and watching the show, it's played straight. Otherwise, it's more a case of Evil Makes You Ugly.
- Big Bad: Final boss of the game, and typically portrayed as the most important of Jim's Rogues Gallery in the cartoons.
- Big Creepy-Crawlies: Her design draws some clear inspiration from termite queens.
- Even Evil Has Loved Ones:
- Invoked in the 1995 comic, where it's established that whilst she doesn't have anyone who loves her, she dearly wishes that she did. She shows up at Princess What's-Her-Name's forced wedding whilst ranting angrily about how unfair it is that she doesn't have a boyfriend of her own, and leaps for the falling wedding bouquet.
- In the cartoon, she forms a very sincere bond with her human neighbor, Ethel Bleveredge, after being temporarily deposed and exiled to Earth. The two are such good friends that Ethel is even able to talk the Queen into giving back Jim's Super Suit after he is forced to loan it to her so that they can defeat Psycrow and Professor Monkey-For-A-Head's ultimate weapon. Ethel then moves onto Insectika to stay with her friend, to Slug-For-A-Butt's delight, and is later shown ruling over the planet as its co-queen.
- Evil Overlord: Albeit she's not very good at it in the cartoons. At the ruling aspect, that is - she gets the "evil" part of it done just fine.
- Fat Bastard: While her main body is pretty much skeletal, her hindquarters... well...
- Fluffy the Terrible: In the cartoon, after being deposed, Slug-For-A-Butt adopts the name "Lucy".
- God Save Us from the Queen!: Somewhat downplayed in the cartoons, where the Princess explains they need to reinstate Queen Slug-for-a-Butt after Psycrow and the Professor depose her because she's such a lousy evil queen that she never actually manages to conquer anything. She is only a pain for her subjects.
- Good Wings, Evil Wings: The Queen has insect wings, but they're so tiny in proportion to her body (mostly to her butt) that she is pretty clearly incapable of flying.
- Insect Queen: Naturally. And since she is meant to be an alien and monstrous example invoked for horror, she rules the majority of the Insecticans as both their Queen and their mother, which gives her absolutely control biologically speaking, as it is a little hard for her offspring to say no to mommy.
- Interspecies Romance: In the cartoon, she temporarily marries a Cuban band-singer during her exile to Earth. Subverted in that she forgets all about him and leaves him on Earth after being given the chance to reclaim her throne, and even before then is shown having trouble actually remembering his name.
- Literal Ass-Kicking: She's on the receiving end of one in the game, as Jim has to defeat her giant butt in order to reach her.
- Odd Friendship: With Jim's Nosy Neighbor Mrs. Bleveredge in "The Exile of Lucy" and "Hyper Psy-Crow".
- Turtle Island: An unusual example. In the games, her rear is so insanely huge, a good part of the final level takes place on or around it.
Henchrat
Evil the Cat's #1 lackey, the masochistic Henchrat lives to obey Evil's every command, thanking him with genuine delight for his abuse. When not on the clock, Henchrat enjoys jumping up and down on hats... while people are still wearing them. Voiced by John Kassir.
- Abnormal Ammo: The Henchrat's choice of weapons consist of exploding mushy cheese grenades and a gun that fires quick-setting melted cheese.
- The Brute: Henchrat serves as the muscle to Evil's brain, and is quite happy with this state of affairs.
- Canon Immigrant: He was introduced in the cartoon series and later appeared with Evil in Menace 2 The Galaxy.
- Catchphrase: "OW! Thank you".
- Hidden Depths: Henchrat enjoys macrame, watching mimes, playing piano and making balloon animals.
- You No Take Candle: His general method of speech.
Evil Jim
A twisted opposite of Jim spawned when a distorted photo-copied image of Jim was exposed to toxic waste, Evil Jim yearns to destroy his heroic counterpart. Voiced by Dan Castellaneta.
- All Girls Want Bad Boys: In "The Anti-Fish," Evil Jim does a better job of wooing the Princess than Jim ever did.
- Canon Immigrant: He was created for the cartoon series but then appeared in the tie in game Menace 2 The Galaxy however and was planned to appear in 3D.
- Evil Is Hammy: Full stop. He's constantly shouting and laughing manically.
- I Just Want to Have Friends: In one episode, Evil Jim gets jealous of Jim's friends and decides to make clones of them for himself. They naturally end up being the exact opposite of the originals in personality and not only in a bad-good way.
- Ironic Echo: Evil Jim states that everything Jim loves, he hates, and vice-versa. However, Jim points out that since he hates losing, Evil Jim must love it.Evil Jim: Oh, don't be so literal-minded. (proceeds to beat up Jim)
- Wicked Cultured: Evil Jim can be very eloquent and mature, when he's not focused on mayhem and destruction.
Evil Princess Whats-Her-Name
One of Evil Jim's attempt to clone himself some evil companions/minions, using a cloning ray to create an evil duplicate of the insectikan princess. Only to realize too late that the opposite of an Action Girl is not as useful as he thought she would be.
- Beauty Equals Goodness: Inverted. Though she is still ugly by her people's standards.
- Brainless Beauty: Funnily enough. The evil clone of the Princess acts more as she did in the game than in the cartoon.
- Evil Knockoff: What she was created for, but leaves much to be desired. Evil Jim lampshades the usefulness of making an opposite personality clone of a mighty warrior woman.
- Girly Girl: Dresses, speaks and acts more feminine than her original counterpart.
- I Broke a Nail: Makes this complaint when using her own gun.
- Oblivious to Love: Inverted. While normal What's-Her-Name can't take a hint or denies Jim affections, Evil Princess has no problem asking Jim out on a date much to his shock.
- Valley Girl: Speaks like this.
- Vanity Is Feminine: Never goes anywhere without her makeup. Demands someone call a hairdresser after getting in a bike crash, which she got in because she was trying to fix her make-up while riding.
Evil Peter Puppy
One of Evil Jim's attempt to clone himself some evil companions/minions, using a cloning ray to create an evil duplicate of the Jim's sidekick. Though he never considered what an opposite clone of someone who turns into an evil monster when upset would entail.
- Bizarre Taste in Food: Unlike Peter, Evil Peter loves Haggis.
- Nothing Personal: His good monster side says as much before pummeling Evil Jim so that the heroes can escape.
- Sesquipedalian Loquaciousness: Instead of a growling savage, his good monster side is very well-spoken.
- Super Powered Good Side: Just as Peter turns into a mindless evil monster that viciously mauls Jim when upset, Evil Peter getting upset turns him into an intelligent, well mannered and good monster who attacks Evil Jim when asked to attack him by his normal counterpart.
