The characters of ''WesternAnimation/TheAmazingWorldOfGumball'' include:


[[folder:The Wattersons]]
!!In general
* ZeroPercentApprovalRating: Some episodes suggest that the Wattersons' antics have made them rather infamous throughout Elmore, or at least thought of poorly. By the end of "The Finale", there is literally a mob breaking the doors to their house down.
* AmazingTechnicolorWildlife: Gumball and Nicole are blue cats, and Anais and Richard are pink rabbits.
* {{Animesque}}: Their facial expressions seem to invoke this.
* BadassFamily:
** In "The Club", the family uses their own odd traits to impressively take out some nerds. Nicole used her anger to take out a locked door, Richard managed to stall another nerd in a board game, Anais used static electricity to short circuit a robot and hacked a computer to intercept Gumball's embarrassing video, and Darwin's dance skills distracted the other nerd into dancing with him. Subverted with [[LoserProtagonist Gumball]] however, who fails to stop the video uploading, and is recognized as so lacking in talent even the nerds don't want to touch him.
** Even moreso in "The Ape" where they work together in a car chase to stop Mrs. Simian after she tricked them.
* BarefootCartoonAnimal: Gumball, Nicole, and Richard. Anais is a FullyDressedCartoonAnimal (oddly, wearing socks with no shoes) and Darwin only wears shoes. On occasions where they break from their LimitedWardrobe, they may or may not wear shoes.
* CheatedAngle: The Wattersons always have their faces in ¾ view, no matter which way their bodies are facing. Darwin's whole ''[[{{Cephalothorax}} body]]'' is always in ¾. Whether they are facing forward or to the side is instead indicated [[ by the position of their ears (or tailfin in Darwin's case).]] When someone attempted to make 3D models of the Watterson family, the head-on views of their face looked... [[ strange]].
* ExpressiveEars: All the Wattersons aside from Darwin have these.
* GenderEqualsBreed: Inverted as they're a female cat and a male rabbit whose children are a male cat and female rabbit.
** Bit of trivia: In the first two seasons, the boys (yes, even Darwin, who's adopted) [[MasculineLinesFeminineCurves have rounded rectangular eyes like their father, while Anais has oval eyes like her mother]], so there's a bit more instances of PlayingWithATrope going on than meets the eye.
* HumanlikeHandAnatomy: When necessary, the Wattersons' hands [[SuddenAnatomy change from]] ovular paws (PowerpuffGirlHands in Darwin's case) to human-like hands with separate fingers.
* PaleFemalesDarkMales: Nicole is a slightly lighter shade of blue than Gumball, but [[InvertedTrope Anais is a slightly darker shade of pink than Richard]].
* PerpetualPoverty: Gumball's trademark sweater was said to have been found in a garbage dump, for goodness sake.
* PinkGirlBlueBoy: Anais and Gumball. Inverted with Richard and Nicole. Both of these even stays true when all of them but Richard [[GenderBender have their genders momentarily reversed]] in "The Job".
* SphereEyes: They all have the separated kind of eyes which are ovular in the first season (the boys' being more rectangular), switching between spherical and ovular in the second season, and always spherical in the third season.
* SuperDeformed: The members of the Watterson Family all have rather large heads even compared to the cartoonish proportions most characters in the show have.
* UncannyFamilyResemblance: An odd example in that ''all five'' of them share the exact same head shape, even both parents and Darwin, who is ''adopted.''

!!Zach "[[OnlyKnownByTheirNickname Gumball]]" Tristopher Watterson/[[spoiler:[[HisNameReallyIsBarkeep Gumball]] Tristopher Watterson]]
-->Voiced by Logan Grove (seasons 1–3); Jacob Hopkins (season 3 onwards)

The main character (as indicated by the title). Gumball is an twelve-year-old anthropomorphic [[AmazingTechnicolorWildlife blue]] [[FunnyAnimal cat]] who attends middle school at Elmore Junior High. A mischief maker and somewhat lazy, the show revolves around his various mishaps around Elmore. Tends to have questionable morals at times and can be a little selfish as well.

* AcquiredSituationalNarcissism: Subverted in "The Name", where he seems to become crazy egotistical after finding out his real name is Zach, [[spoiler:but is actually suffering from [[SplitPersonalityTakeover a much more serious problem.]]]]
* ActionSurvivor: He survives a ton of encounters that would kill most regular kids.
* {{Adorkable}}: On his better days.
* AllGuysWantCheerleaders: Gumball has a crush on Penny, a peanut with antlers who is one of the [[TheCheerleader cheerleaders]] at Elmore Junior High. The feeling is mutual, but [[CannotSpitItOut neither of them are capable of expressing it.]]
* AmbidextrousSprite: He always has three whiskers on one side and two on the other, but the pattern tends to flip as a result of this. It is likely meant to convey perspective, where his face is actually symmetric [[CheatedAngle but never seen from the front]].
* AnimalsHateHim: Penny's pet tarantula viciously attacked him on sight, and the family's turtle is stated to especially like biting him.
* AnnoyingYoungerSibling: {{Inverted|Trope}}. He's older than Anais, and often acts annoying toward her. On a few occasions he goes beyond "annoying" and is more of a BigBrotherBully, most prominently when left Anais out of a party in "Halloween" by hanging her from a tree branch.
* AttractiveBentGender: When he's forced in a dress in "The Dress", everyone instantly likes him and calls him beautiful. It helps that he takes after Nicole, though it might have just been the dress which was really nice.
* BadassPacifist: In "The Sweaters", he and Darwin both refuse to engage the students from the other school in their idiocy, and ultimately "win" (in the sense of being the only ones who don't look like complete idiots) because they don't play along.
* BadLiar: Gumball can bluff, doing an excellent (unnecessary) job of PlayingTheVictimCard in "The Sweaters" and taking advantage of the killer virus's pride in "The Virus", but he acts incredibly nervous any time he tries to lie to his mother.
-->'''Nicole:''' Honey, are you in trouble? Because my mother senses are tingling. I can smell trouble.\\
'''Gumball:''' ''(laughing nervously)'' Trouble? No, we're fine. Absolutely fine. No trouble here, bye.\\
'''Nicole:''' Are you lying?\\
'''Gumball:''' Ha! Oh, no, of course not.\\
'''Nicole:''' Right. You're lying. I'm coming home now.
* BathsAreFun: In "The Burden" Gumball and Darwin are enjoying taking a bubble bath in a montage.
* BrilliantButLazy: When he puts his mind to it and isn't trying to show off, Gumball shows a surprising amount of intelligence and athleticism.
* BuffoonishTomcat: Played entirely straight in the first season, especially compared to his mother. Downplayed after that, where he's halfway between this trope and CatsAreSnarkers.
* CannotSpitItOut: Does this in "The Bros" when he's trying to ask Penny to marry him.
* {{Catchphrase}}:
** "*sigh* (aggravated) Fine..."
** "What the what!?" became a semi-recurring line of his in the second season--it was even used as a MadLibsCatchPhrase a couple times ("What the droid?", "What the wasp?") and mocked by Darwin's impersonation of Gumball in "The Sidekick".
* CatsAreMean: {{Downplayed|Trope}} in that he's not usually cruel and can be very kind, [[JerkWithAHeartOfGold but tends to be quite selfish, judgemental, and insensitive.]] Later on he takes this attitude and combines it with CatsAreSnarkers, constantly making lines [[BrutalHonesty that are as mean as they are accurate.]]
-->'''Darwin:''' (imitating Gumball) Duh, hey Sussie! While conveniently ignoring my own character flaws, I'm happy to point out that you eat with the grace of a one-toothed camel!
* CatsHateWater: Averted, judging by how long he took his shower in one episode. Gumball also seems to love taking baths as seen in another episode. How well he can actually ''swim'' is inconsistent: he could just fine in "The Responsible", but couldn't at all in "The Club".
* CharacterizationMarchesOn: Initially very childlike and naive (much like Darwin), it wasn't until season two that he became the [[TheCynic cynical]], [[DeadpanSnarker sarcastic]] JerkWithAHeartOfGold we know and love.
* TheChewToy: AmusingInjuries are quite common, but Gumball seems especially prone to them.
* ClassicalAntiHero: In spite of his lack of physical fitness, intelligence, and maturity, he's usually the most likely one to save the day (although he causes these problems just as much).
* CoolCat: Gumball often attempts to give off this type of cool, collected confidence, but rarely lives up to it. Perhaps [[EstablishingCharacterMoment best demonstrated]] in "The Responsible", where he nearly drowns, vomits up a bunch of water in a panic, then immediately snaps into a relaxed posed and acts unphazed.
* CowardlyLion: Gumball is a self-described coward, but manages to get by in dire situations even if he spends most of them freaking out.
* CrazyJealousGuy: He gets insanely jealous at the ''suggestion'' of another guy dating Penny, even getting MadAtADream where Darwin kissed her despite him showing no interest in real life.
* CrouchingMoronHiddenBadass: If his loved ones are threatened or insulted, Gumball can prove much more mature, clever, and determined than he usually is.
* CuteKitten: He can be cute when he wants to be.
* CuteLittleFangs: His canines aren't visible when his mouth is closed, but are any time it's open and the teeth on his upper jaw aren't being used as part of his expression, even if no other teeth are shown.
* TheCynic: Although initially very optimistic, he develops a strong tendency to expect the least out of people (himself included). The most obvious example would be "The Bumpkin", where his cynical outlook on modern society is a primary plot element.
* DeadpanSnarker: He gets increasingly snarky as the show goes on, especially regarding Darwin. It becomes especially apparent throughout the second season, and compliments his VocalEvolution (see below) quite nicely, actually.
* DependingOnTheWriter: His level of intelligence varies from episode. Sometimes he's a complete idiot, sometimes he's just mischievous, sometimes he just acts like a dork, sometimes he's the OnlySaneMan. Since the latter half of Season 2, his OnlySaneMan status became the more distinct of them all.
* DetachmentCombat: It's not used for combat, but Gumball seems to be able to function perfectly whenever a body part gains autonomy.
* {{Determinator}}: In "The Third" he rides a tricycle through miles of hills, flies down a hill so fast he catches on fire, and gets covered in quick drying cement (which he promptly breaks through) just to prove that he and Darwin are still friends.
* EmbarrassingMiddleName: "The Club" reveals that his middle name is Tristopher, or in shortened form, "Trisha"--it was supposed to be Christopher, but Richard wrote it down wrong.
* EmbarrassingNickname: "The Meddler" has his mom calling him "Gummypuss".
* EveryoneHasStandards: For all the mischief he causes, he finds himself ''physically incapable'' of shoplifting even a candy bar and slaps himself in the face for trying. Ironic, given he's several times demonstrated he's [[ImpossibleThief extremely good]] at stealing things, even from his own mother, or planting them on other people.
* FashionableAsymmetry: He has two whiskers pointing forward and three pointing backward, [[AmbidextrousSprite regardless of the direction he's facing.]]
* FirstKiss: He had two or three {{Accidental Kiss}}es, with [[spoiler:Darwin, Carmen, and possibly Sussie]], then had his first ''intentional'' kiss [[spoiler:with Penny.]]
* GenerationXerox: While obviously similar to his father, Gumball is also similar to his mother in the past, as they both get called losers by the kids or Miss Simian, which is why Nicole wanted to make him a winner in "The Fridge". He and Penny's relationship mirrors Nicole's with Richard growing up as well as Gumball, like his mother, encourages Penny to be herself [[spoiler:and come out of her shell]].
* GenreSavvy: He almost avoided the plot of "The Sweaters" by simply admitting to [[NewTransferStudent Sarah]] that he's not actually hardcore rather than continue the lie. He also successfully predicted the entire plot. [[ContractualGenreBlindness He goes through the ordeal anyway]], mainly because of the worry Penny was giving him.
* GoshDangItToHeck: Gumball frequently uses non-profanity, often with the emphasis and tone people [[ParentheticalSwearing usually reserve for actual profanity]] (including an [[AtomicFBomb Atomic]] ''Darn'' Bomb in "The Third"). In "The Safety" he claims that he doesn't even ''know'' any real swear words.
* HartmanHips: A rare male example; his hips are twice the width of his chest. Clearly, he gets it from his mom.
* HiddenDepths:
** Some episodes show that Gumball is a really good cook: he did very well in home ec class and seems to make his own meals a lot because him mom is so busy.
** He's able to sketch a pretty decent (if [[FourthWallPortrait strange]]) portrait of Darwin in "The Procrastinators".
* IdiotHero: He does get a little smarter, though, later on.
* InterspeciesRomance: With Penny.
* IronButtMonkey: Gumball is, to put it bluntly, [[NighInvulnerability indestructible.]] He's survived [[NotTheFallThatKillsYou falling off a cliff]], [[BarrierBustingBlow being punched through a wall]], and even [[ArsonMurderAndJaywalking being flushed down the toilet]].
* JerkWithAHeartOfGold: While he can be exasperated with others and often does some dumb or insensitive things, he's a good kid and will go out of his way to try and help.
* {{Keet}}: Early on in the series he is almost perpetually bright and energetic. This trait becomes less pronounced later on, as he becomes plenty capable of apathy and cynicism.
* LoserProtagonist: Lazy, irresponsible, unathletic, BookDumb to a [[TooDumbToLive sometimes dangerous degree]], and usually falls victim to endless abuse each episode. Worsened in that he isn't ''enough'' of a deadbeat loser like his father, who can [[IdiotHoudini reverse it around in his favor]].
* LoserSonOfLoserDad: A lot of Gumball's negative traits he has in common with his father.
* NoSenseOfDirection: He think he can somehow memorize a map ''after eating it'' and when the wind is directly speaking to him, in plainly decipherable language, he does the exact opposite of what it tells him.
* NotSoDifferent: He orders his whole family around frantically to make his study date with Penny in "The Knights" perfect, showing he is capable of being just as neurotic, controlling and raging as his mom.
* OfficialCouple: with Penny
* OnlyKnownByTheirNickname: "Gumball" is actually a nickname, but until "The Name" nobody but Nicole knew his real first name was "Zach"--not even ''Gumball himself''. [[spoiler:Then "Zach" becomes a [[JerkAss intolerable]] SplitPersonality [[SplitPersonalityTakeover who tries to replace Gumball]], so he [[HisNameReallyIsBarkeep legally changes his name to "Gumball"]] to get rid of him.]]
* OnlySaneMan: While he was a mix of this, being simply mischievous, hyperactive or stupid, this is slowly becoming his most seen side. The best example is in "The Fridge," being the only family member not worked up into a competitive spirit (started by his mother) and forced to bring the family back to normal.
* TheProtagonist: As the title indicates; after more than one hundred episodes, "The World" and "The Extras" are the only episodes where he ''doesn't'' play a major role.
* RealMenWearPink: Gumball once had his hair permed and then asked if he could have a pet pony. In "The Meddler", he showed a real (and comical) interest in being a cheerleader, even thinking it would prove how manly he was.
* RelationshipUpgrade: [[spoiler:After their BigDamnKiss at the end of "The Shell" he and Penny are now dating.]]
* RidiculousProcrastinator: He's puts off things like returning/replacing [=DVDs=], studying, and chores as long as possible. According to Nicole, his first sentence, said at the age of four, was "I'll do it tomorrow."
* RubberMan: Gumball has been shown numerous times to be incredibly elastic. In "The Virus", he shows has complete control over his entire body to an unsettlingly complex degree...though he will unintentionally move his internal organs around, requiring him to go to the nurse.
* ScreamsLikeALittleGirl: His screams are very high pitch, especially in the first season when his first actor's voice was cracking.
* SingleTargetSexuality: The only girl that has stolen Gumball's heart: Penny Fitzgerald. When he needs to get a date in "The Party" but can't bring himself to ask Penny, he doesn't show romantic interest in any of the other girls he asks, instead treating it like some strange chore.
* SmallNameBigEgo: Early on Gumball is very vocal of his non-existent competence and ability, and how sincere he's being [[InferioritySuperiorityComplex is rather questionable.]] This tended to make him TheMillstone toward the smarter but less assertive Darwin, and a frequent subject to BreakTheHaughty. Later on, he's far more self-deprecating and aware of his own flaws, albeit seemingly [[DeadpanSnarker mocking everyone else]] a lot more to compensate. This trait still shows up occasionally; he's still particularly reluctant to acknowledge his own physical weakness.
* SuperPoweredEvilSide:
** Jealous Gumball in "The Flower", which was strong enough to [[FoeTossingCharge smash through a team of giant football players]].
** Zach in "The Name", who supposedly succeeds at [[ButtonMashing almost]] everything Gumball fails at and [[CrazyPrepared "always thinks ahead"]]. However, he ''refuses'' to admit where he fails at unlike Gumball but his ego is big enough to cloud such mistakes.
* SupremeChef: Shown to be at least decent in cooking in the episode "The Secret", . Miss Simian has also called his cooking 'divine' and has gotten a B in home economics because of said cooking. Though he did make a hilariously bad meal for Anais in "The Responsible", though it may have been RuleOfFunny at work.
* StrongAsTheyNeedToBe: His level of physical fitness is ''heavily'' subject to the RuleOfFunny and RuleOfCool. He's stated to be in such terrible shape that he can't overpower a girl made of paper and his organs have a fit doing basic exercises, but when a ChaseScene happens he's perfectly capable of keeping up or even pulling LeParkour moves that rival his mother's.
* StrongFamilyResemblance: He looks almost exactly like a shorter version of his mother. Comparing how she looked at his age, the only difference besides clothes was that she was taller, usually has visible eyelashes, and her whiskers look different. In "The Plan", he even tries to impersonate her and since he obscures the huge height difference by standing in a bush, it was amazingly effective.
* TinyGuyHugeGirl: He's considerably shorter than Penny, though how much varies by the scene.
* TookALevelInJerkass[=/=]TookALevelInKindness: A somewhat mixed case that came with his [[DumbassNoMore increased intelligence and maturity]]: in the first season, Gumball usually had a pleasant demeanor, but could be incredibly selfish or rude because he didn't know any better. After then, he has the emotional intelligence to understand people and their problems, but when he's being mean or insulting it's ''intentional''. Even his moments of insensitivity are portrayed less as [[InnocentlyInsensitive innocent]] and more like willful ignorance.
* TwiceShy: His feelings for Penny are mutual, but both struggle to confess to each other. [[spoiler: As of "The Shell", they're official.]]
* VerbalTic: He tends to squeak, usually when he's yelling. Some of this just seems to be due to Logan Grove's voice cracking.
* VocalEvolution: His voice cracked a lot in the first season and, along with Darwin's, got deeper over the course of the first two season as his VA got older.
* WholesomeCrossdresser: "The Tape" shows he has no problem with wearing a girl's skirt.
* WhoNamesTheirKidDude: His odd (nick)name is sometimes commented on, most notably by Mr. Small in "The Banana".
* WhyDidItHaveToBeSnakes: "AHHH, spider! Knock his block off!"
* WithGreatPowerComesGreatInsanity: He missed the extreme luck he got from the eponymous hat in "The Helmet" and went insane with using its power once he got it back.

!![[OverlyLongName Darwin Radlin Caspian Ahab Poseidon Nicodemus Watterson III]]
-->Voiced by Kwesi Boakye (season 1–3); Terrell Ransom, Jr. (season 3 onwards)

Gumball's ten-year-old [[UpliftedAnimal pet goldfish-turned-family member]] who sprouted legs, grew in size, and began to talk. Gumball and Darwin are seen as brothers (Darwin even calls Nicole "Mrs Mom" and Richard "Mr. Dad") and attend the same school and class. Darwin is a bit naive due to his forced adaptation among the "normal" world, though he is more rational and moral than Gumball.

* AccessoryWearingCartoonAnimal[=/=]TheOneWhoWearsShoes: The only clothing Darwin wears are shoes, and he's the only one in his family who does so (though Anais wears socks). Lampshaded by Darwin's feet will often be [[OurNudityIsDifferent subject to pixellation in the same way Gumball's crotch it]].
** Mentioned by Anais in "The Job", where she states that they've been wearing the same clothes for a year and that it's time for Darwin to start wearing pants.
** When series director Mic Graves was asked in an interview why Darwin didn't wear pants, he pointed out Darwin doesn't have any buttocks to put them on. Although Darwin actually [[SuddenAnatomy does have them, sometimes]].
* ActualPacifist: Darwin claims to be a "[[{{Pun}} Pacifish]]" in the first season. [[BewareTheNiceOnes This changes]] [[BewareTheSillyOnes in Season 2.]]
* {{Adorkable}}: More so in season 1, where his naivete is played up more often than Gumball's.
* AwesomeMcCoolname: His full name includes a famous scientist, a sea, a captain from classic literature, and the Greek god of the seas.
* BadassPacifist: In "The Sweaters", he and Gumball both refuse to engage the students from the other school in their idiocy, and ultimately "win" (in the sense of being the only ones who don't look like complete idiots) because they don't play along.
* {{Bad Impressionist|s}}: On the phone with Nicole in "The Flakers", trying to impersonate Richard (while speaking in his own usual high voice) after discovering that he has escaped the house:
-->'''Nicole''': Can you pass me onto him, please?\\
'''Darwin''': Um, yeah... one minute!\\
''(clears throat and tries to impersonate Richard)''\\
'''Darwin''': Hello, [[SomethingOnlyTheyWouldSay Mrs. Mom]], what's for dinner?\\
'''Nicole''': ''(unconvinced)'' Really?\\
'''Darwin''': ''(defeated)'' Y-ep.
* BadLiar: Neither he nor Gumball could resist darting their eyes to the side when lying to Anais.
* BaldOfAwesome: His lack of NonMammalianHair is frequently pointed out.
* BewareTheNiceOnes[=/=]BewareTheSillyOnes: He becomes a lot more aggressive when provoked in the second season; a prime example would be "The Banana", when he vandalizes Banana Joe's locker and tries to get in a fight with him for damaging his homework.
* BigBrotherAttraction: If dressing himself as ''Penny'' just for Gumball to show his love doesn't scream this trope, I don't know what does.
* {{Cephalothorax}}: Played with; he's a fish that grew legs, so he technically has a separate head and body. However, his fish parts are highly stylized and his face is disproportionately large, meaning he'd basically be a FlyingFace without his human-like arms and legs.
** Referenced several times. Gumball once made angry grabbing motions in the air, saying that he was trying to strangle Darwin but couldn't because he doesn't have a neck. Also given as the reason he doesn't wear a shirt or pants, although he wore a collar and tie around the part where his legs meet his body in "The Puppy".
* CheerfulChild: Under most circumstances, he's a pretty happy guy. [[BewareTheNiceOnes When he isn't...]]
* TheConscience: He has a higher moral sense than Gumball does and will usually voice his concerns. In "The Sidekick", Gumball tells him that he counts on Darwin to stop him from going through with especially bad ideas.
* CreepyChild: Surprisingly, despite him [[TheConscience having a higher moral sense]] and [[NiceGuy being a decent guy]], Darwin has shown instances of being this trope.
** In "The Limit", when he and his siblings are sent to the car after throwing a tantrum for not getting candy, Darwin, suggests this solution of getting their mother back:
-->'''Darwin:''' "You know what we should do? We should make full-sized paper models of ourselves, set the car on fire, and push it off a cliff to teach Mom a lesson." ''(Cue the looks of horror on Gumball and Anais's faces)''
** In "The Sidekick, Darwin's idea of making Tobias give back their game is to '''''kidnap his mother.''''' Gumball understandably [[WhatTheHellHero calls Darwin out on his idea]] and at one point calls him a "psycho".
* DeadpanSnarker: Well, usually his snarking is a lot more cheerful, but he gets more and more of it after the first season.
* DependingOnTheWriter: Like above, his level of intelligence also varies depending on the episode, as does how peaceful and innocent he is. There's a general shift over time, from hopelessly naive and ignorant to mostly moral and positive, but prone to snark and a severe case of BewareTheNiceOnes.
* {{Deuteragonist}}: He has at least a secondary role in more episodes than anyone but Gumball.
* FishOutOfWater: A literal example.
* GenreSavvy: Like Gumball in "The Sweaters"
* GreenEyedMonster: He gets incredibly jealous of the attention Gumball gives to Penny [[spoiler:once they start dating.]] The fact that he was immune to being possessed by jealousy in "The Flower" implies this is the first time in his ''life'' he's ever been jealous.
* HappilyAdopted[=/=]InterspeciesAdoption: Darwin's treated like as much of a member of the family as Gumball is. Although legally, he's still registered as a pet.
* IncorruptiblePurePureness: When taken over by Jealousy in "The Flower" he's the only one with no spite or envy of anyone else, instead just stating he's "actually quite happy with my life". Gumball took a peek inside his head in "The Sweaters" to see if he had any guilt, and just saw a brilliant shining light come out.
* InnocentlyInsensitive: Whether he unintentionally offends or not varies.
* InsistentTerminology: He considers himself to be/have been an "Animal Companion", not a pet.
* {{Keet}}: In early episodes he's almost unfailingly energetic. He becomes less so later on, but he's still usually more upbeat and optimist than Gumball.
* LegacyCharacter: As his full name states, he's the third Darwin Watterson, the first two having been regular goldfish their whole lives.
* MeaningfulName:
** He was once the family pet fish but then he sprouted legs and doesn't need water to breathe anymore. [[CharlesDarwin Think about that for a second.]]
** His middle names all have nautical connections.
* NamedAfterSomebodyFamous: ''Several'' somebodies.
* NiceGuy: He becomes more aggressive from the second season onwards, but he still remains a CheerfulChild. When he was possessed by a spirit of jealousy, he reveals that "[he's] actually quite happy with [his] life" and holds no spite or envy towards anyone else.
--> '''Darwin''': Is he gonna cry? Because if he cries, ''I'll cry!''
* ObsessedWithFood: He tends to think with his stomach from time to time as most fish seem to do.
* OnlySaneMan: Though not necessarily the ''smartest'' person in any episode he's in, he's traded off on the role of "the only person being objective while everything's going nuts" with Anais on occasion, and has started playing the StraightMan to Gumball's antics more. Gumball basically says in "The Sidekick" that his role in their dynamic is to stop him from doing really crazy things. Though at times, such as "The Sidekick", "The Phone", and "The Banana", roles switch and he actually acts ''worse'' than what Gumball does.
* OverlyLongName: In "The Party", he reveals that his full name is Darwin Radlin Caspian Ahab Poseidon Nicodemus Watterson III.
* PureIsNotGood: Darwin's innocent nature usually makes he fairly kind, but if exposed to certain events that Gumball is up to, he can be worse than him. Even in the first season it was implied he had a lot of pent up rage he was too innocent to express properly: Darwin's attempt to yell out his stress in "The Painting" produced a ''nuclear explosion'', during which he continued smiling.
* SarcasmBlind: In season 1, he failed to understand sarcasm often, especially from Anais. In season 2, he snarks with the best of them.
* SpeaksFluentAnimal: He's able to guess what Chris Morris the hamster says in "The Burden" and speak squirrel in "The Question", probably because he used to be a pet. Of course, all the animals [[EverythingTalks can speak and understand English]] anyway, making it a bit of a moot point.
* StepfordSmiler: In "The Meddler", Darwin constantly smiles to hide his displeasure of Nicole coming to school--later on he keeps doing so because he forgot how to stop. In "The Gripes", he keeps smiling while trying to cheer up an unreasonably-grumpy Gumball, barely restraining himself from smashing his head in with a toaster, until he collapses into whining along with him.
* TookALevelInJerkass: Generally, he's much more snarky and aggressive in season 2, almost being on the same level as Gumball himself when he's supposed to be more righteous than him. [[TookALevelInKindness On the other hand]], Darwin thereafter avoids the InnocentlyInsensitive remarks he sometimes made in the first season, often to the point of being excessively considerate.
* ToothyBird: Despite being a fish, Darwin has teeth that are even more humanlike than the rest of the family's.
* TrademarkFavoriteFood: Fish flakes, apparently.
* UpliftedAnimal: Notably, while this can happen to anything, he's the only character stated to have become human-like rather than being born that way.
* VocalEvolution: Along with Gumball, his voice got deeper over the course of the first two season as his VA got older. Darwin's voice actor appears to have started puberty slightly later, resulting in Darwin's voice breaking often in season two, something Gumball's voice had mostly stopped by the end of season one (which make sense in-series because Darwin is two years younger). Gumball even mocks Darwin for it in "The Castle".
-->'''Darwin:''' Dude, have you noticed that your voice has changed? \\
'''Gumball:''' What, you mean I sound like a man and you squeal like a piglet on helium?

!!Anais Watterson
-->Voiced by Kyla Rae Kowalewski

Gumball's sister, a genius four-year-old [[AmazingTechnicolorWildlife pink]] [[FunnyAnimal rabbit]]. Due to her high intelligence, she attends Gumball and Darwin's middle school as well, though in a different class. Despite her competency, she still displays some traits of a typical four-year old.

* {{Adorkable}}: We see a much more awkward side of Anais in "The Friend" as she tries to make friends for the first time.
* AnnoyingYoungerSibling: Gumball is far more likely to annoy her, but she starts to have [[NotSoAboveItAll her own moments of acting bratty]] in the second season.
* BadassAdorable: She managed to flip ''Richard''.
* BerserkButton: Suggesting that Daisy the Donkey was just a doll made her react with an absolutely monstrous looking face.
* TheChessmaster: In "The Remote", she manipulates the entire rest of the family to lock them outside while she watches TV. She does it again in "The Password," where she tricks Gumball and Darwin into thinking their parents favor her over them just so she can get time on the computer to herself.
* ChildProdigy: Despite being four years old, she is described as the smartest character on the show and even attends Junior High with her much older brother; she is apparently at a ''higher'' class than he is.
* GoldDigger: As mentioned below, she wants to marry a prince eventually so that she can basically live like her dad.
* GradeSkipper: She attend middle school at the age of four, [[ExaggeratedTrope two years before most children have even started grade school]].
* FriendlessBackground: We never see her with any friends, and "The Friend" shows this is because she doesn't have any.
* ItIsPronouncedTroPAY: Subverted. Her name is pronounced both as An-eye-ees and An-ai-ahs, typically varying by character (and voice actor) and she never favors one over the other. Given that the character is named after Ben Bocquelet's sister and both have French heritage, it's most likely "An-eye-ees".
* KnightOfCerebus: If an episode has Anais as the main villain everyone is 100% guaranteed to lose in the end.
* KillerRabbit: Let's just say her mom's gonna have some competition when she grows up.
* LittleMissSnarker: Only 4, and a veteran master of snark.
* NotSoAboveItAll: She's considerably more child-like--or even flat out crazy--when it comes to anything involving Daisy the Donkey. More generally, she's far more likely to involve herself with her brothers' hijinks from the second season on, even if she's usually [[TheSmartGuy smarter about it]], compared to the first where she almost always [[OptOut refused to let herself get caught up in it]].
* OddFriendship: She forms one with the strange monster in "The Friend".
* [[OnlySaneMan Only Sane Girl]]: Can be her or can be her mother, depending on the episode.
* PintSizedPowerhouse: She is depicted as being able to lift way more than her body weight, such as when she carried a ton of luggage upstairs and the time she carried Darwin with a bunch of stuff on him all the way to the top of a mountain.
* RascallyRabbit: Although typically well-behaved, she can be very manipulative when it benefits her.
* TheSlacker: Ironically, she's often been shown to share some of her father's laziness. Anais seems to study more because she enjoys it than any practical benefit, and has joined with her brothers in laying around and eating junk food on Saturday. Despite being a genius, Anais expresses some decidedly unambitious life goals when giving her Christmas list:
-->'''Anais:''' I want a princess tiara and a prince to marry me when I'm old enough so I never have to work like [[{{Workaholic}} Mom]].
* [[StraightMan Straight Girl]]: Usually. She's the most serious character on the show, but sometimes she slithers away from this.
* StrongAsTheyNeedToBe: Like Gumball, her level of physical strength varies a lot depending the needs of the plot or the joke. Sometimes she's a PintsizedPowerhouse almost as strong as Nicole. Other times, she's explicitly weaker than anyone else in the family and needs their assistance to get by and to trick them to come out ahead.
* {{Tuckerization}}: Named after Ben Bocquelet's younger sister.
* [[TheUglyGuysHotDaughter The Ugly Guy's Cute Daughter]]: Especially noticeable in that when we see Nicole and Richard as children, you see Nicole and Gumball looks very similar but Anais doesn't really look like either of her parents (she does look a lot like Granny Jojo, though).
* UnspokenPlanGuarantee: Her level of intellect seems to hang on this formula. She's great at rolling her eyes and explaining all the things wrong with her brothers' latest ZanyScheme, but when it comes to pulling off her own plans, she tends to fall flat on her face.
--> '''Gumball:''' Hey, where is everyone?\\
'''Anais:''' I don't know! I prepared everything and no one came [[Recap/TheAmazingWorldOfGumballS3E30TheFriend [to my party]!]]\\
'''Darwin:''' Did you invite anyone?\\
'''Anais:''' [[InsaneTrollLogic Of course not. I have no friends.]]\\
''[[{{Beat}} *Moment of realization kicks in.*]]''
* VocalEvolution: It's not as obvious as her brother's because she's a girl, but her voice has gotten significantly deeper since the show started. Depending on the scene, this can make her sound more mature, angry, or sarcastic. For reference, Kyla Rae Kowalewski was more than twice Anais's age when the show ''started''. Since Darwin and Gumball were recast in the third season but Anais wasn't, she is now the Watterson child with the oldest VA.
* WackyParentSeriousChild: The serious child to Richard's wacky parent.
* WiseBeyondTheirYears: She usually acts much older than her age in terms of knowledge and maturity.
* WhenSheSmiles: In "The Pony", Darwin and Gumball consider the hoops they'd jumped through to watch a movie with her worth it because they get to see [[ "the happy face"]].
* WomenAreWiser: The most consistently levelheaded member of the family.

!!Nicole Watterson
-->Voiced by Teresa Gallagher

The maternal member of the Watterson family (and a [[AmazingTechnicolorWildlife blue]] [[FunnyAnimal cat]] like Gumball). She holds down a job at the rainbow factory and appears to be the only member of the family with any sense of responsibility. She's normally collected and organized but when things go awry, she succumbs to violent bouts of anger (almost always sparked by her sons).

* AbusiveParents: Sometimes she could be this despite being the OnlySaneMan. She leaves Gumball alone in a desert at one point and refuses to take care of Gumball and Darwin until they respect Richard, something she doesn't even do. Her children are so scared of her that, in the episode "The Quest," Gumball and Darwin agree without hesitation that they'd rather face [[TheBully Tina]] [[EverythingsBetterWithDinosaurs Rex]] than incur Nicole's wrath.
* ActionMom: She's super-humanly athletic and not afraid to get physical.
-->'''Gumball''': The woman is virtually a ninja.
* AlmightyMom: You don't want to mess with her. She's been known to bring a fully grown tyrannosaurus rex to his knees.
* {{Amazingly Embarrassing Parent|s}}: In "The Meddler" she decides to follow Gumball around at school everywhere, even in the public shower, doing things such as feeding him like a baby and calling him "Gummypuss".
* AmericanAccents: While most of the cast have [[FakeAmerican affected]] "generic/newscaster" accents, Nicole's sometimes sounds a bit more [[WhatTheHellIsThatAccent untraceable]], usually when she's speaking calmly.
* {{Badass}}: To the point where, [[ItMakesSenseInContext after she went berserk after a bad day grocery shopping]], she melted a trap she was in with [[ThePowerOfHate pure rage]].
* BerserkButton: '''MANY'''. Being called a loser (at least by Miss Simian), threatening her family and disrespecting her authority. And '''DON'T YOU DARE''' run away from her if she finds out you're in trouble.
* BewareTheNiceOnes: She is sincerely nice, but sometimes she can get really violent, so it's best you run for it if she does.
* CatsAreMean: Averted; she's quick to anger, but by default quite nice.
* ChildhoodFriendRomance: Has known her husband, Richard, at least since they were Gumball's age.
* CompetitionFreak: She has a huge drive to win. This is arguably her biggest flaw.
** In "The Fridge", she wins the company paintball game by shooting everyone, even her own teammates, to win the game as well as sucking most of the family into an achievement binge (Gumball being the OnlySaneMan.) She tried to pull a ISurrenderSuckers moment to Gumball during the family paintball game before he finally wins and has the chart removed.
** She cheats Anais out of six spaces while playing "Dodge or Dare" with the family in "The Game" through LoopholeAbuse.
** When Richard tries to buy Gumball and Darwin's favor over her, she escalated things into a cross-town car chase.
* ControlFreak: Pointed out by Anais in "The Job." Anais thinks Nicole is worried about Richard working as a pizza delivery guy because she thinks it's upsetting the balance of power in the house. [[spoiler:Although she's right that there's a bigger problem with that: namely that Richard having a job will destroy the universe.]]
* CuteBruiser: Don't make her mad. She is a ''lot'' stronger than she looks.
* CuteLittleFangs: Like Gumball, they're only visible when she opens her mouth (in the first season they [[DependingOnTheArtist sometimes]] didn't even show up then).
* {{Determinator}}: She gets scary when she gets mad and probably can and '''will''' chase you down. "The DVD" and "The Limit" are based entirely on these moments.
* DeathGlare: Her glare pretty instantly gets her family in line and is capable of having a physical effect. "The Castle" gives her [[ComicBook/GhostRider Glowing White Eyes]] swirling with ghosts enough to frighten even the most delinquent person in Elmore. In "The Limit", her stare manifests a shockwave that knocks all the cans off a shelf, melts a plastic-wrap barrier, and frightens a security guard so much, his hair turns white... ''and stays that way in future episodes''.
* DotingParent: When her kids aren't doing something reprehensible, she can be quite coddling toward them, especially in "The Meddler".
* TheDreaded: Her own family is scared of her, especially when she gets mad. Case in point: in "The Quest," Gumball and Darwin both agree that suffering Tina Rex's wrath is better than suffering Nicole's.
* EverythingsBetterWithRainbows: Nicole always wears a pin with a ([[RainbowLite partial]]) rainbow design on her shirt. She works at the Rainbow Factory, so it's presumably a part of the dress code.
* FreudianExcuse: "The Ape" seems to indicate Nicole's type-A personality and drive to be a winner by any means necessary stems from Miss Simian calling her a loser from the time she took her first steps to the day she got married.
* FullNameUltimatum: Subverted as she never uses Gumball's EmbarrassingMiddleName [[OnlyKnownByTheirNickname or even his real first name]], it's always "Gumball Watterson".
* HairTriggerTemper: Nicole cares for her family, but easily becomes upset when she discovers they did something wrong. She's even taking anger management classes, in which her behavior is far worse than she acts elsewhere.
* HartmanHips: Not including her head, her hips are the widest feature of her body.
* HugeGuyTinyGirl: She's regular sized, but absolutely dwarfed by Richard.
* HulkingOut: She starts doing this when Larry closes the store gates on her in "The Finale" and she starts pulling them up. Odd, given similar or even greater feats of strength she's previous done [[MusclesAreMeaningless required no such musculature.]]
* InterspeciesRomance: With Richard.
* JerkWithAHeartOfGold: She is a kindhearted mother and wife, but sometimes her stress can really get the best of her.
* KillerRabbit: She has proven herself to be made of this trope in countless episodes, most notably in The Fight, where she mercilessly tears through Tina Rex's father just at the mere inkling of assuming that Gumball was being bullied.
* LeParkour: She's very good at jumping and climbing over fences, walls, and even between buildings.
* MagicSkirt: Her skirt does not go above her legs during any of her running, [[LeParkour jumping]], or even when she's [[UnwillingSuspension hung upside down]].
* MasculineGirlFeminineBoy: Masculine Girl to Richard's Feminine Boy.
* MamaBear: She's VERY protective of her own family.
* MusclesAreMeaningless: In spite of her arms and legs being quite skinny, she's capable of things like bending steel rods and tearing locker doors off their hinges.
* NotSoAboveItAll: Nicole would be insufferable if not for her insecurity and occasional lapses in judgment.
* ObliquelyObfuscatedOccupation: We know Nicole works at the Rainbow Factory, but her job there is rarely shown and possibly may have changed between episodes. We don't know exactly what the factory ''itself'' does, and despite the name she definitely works some sort of office job. In "The Helmet" she almost gets a promotion, but when she finds out Richard tricked her she throws a fit that she was apparently fired for. In "The Game", however, she's still working there at the complaints department.
* [[OnlySaneMan Only Sane Woman]]: Depends on the episode, which sometimes gives the role to Anais instead. However, when her temper or competitive streak get the better of her, this aspect goes out the window.
* ParentingTheHusband: Nicole often has to parent Richard, due to his own mother having been responsible for his childish nature in the first place. At the same time, Nicole deliberately scolds him less than their children--not because he's an adult, but because she's ''given up'' on him getting any better.
* {{Tuckerization}}: Named after Ben Bocquelet's mother.
* ShipperOnDeck: Nicole was happy to notice Gumball's crush on Penny in "The Gi", was proud that he (thought he) had a date with her in "The Date", and tried to get him to confess about his feelings to her in "The Meddler". Possibly it's because Penny reminds her very much of herself in her childhood when she had a crush on Richard and defended him.
* UnstoppableRage: She's plenty strong and athletic by default, but when she's angry she gets [[SuperStrength superhuman strength]] and [[RuleOfFunny sometimes]] [[NewPowersAsThePlotDemands other, stranger abilities]] (like melting objects and reducing grown men to tears by staring at them). In "The Club", she even has to ''ask'' her family to enrage her somehow so she can pull a door open.
* UglyGuyHotWife: An adorable cat woman, married to a fat, slobbish man bunny.
* VoiceOfTheLegion: When sufficiently pissed off, her voice gets really deep as well as echoing.
* WhatDoesSheSeeInHim: Richard is by no means a bad person, but he is lazy, irresponsible and pretty offbeat (albeit he was raised that way). She does admire that he is true to himself and that he's a good person, but we don't know what else. Considering her need for control, most other people would either not be able to handle her or other negative consequences.
* WomenAreWiser: Usually this, barring her competitive nature doesn't cause her to go nuts.
* {{Workaholic}}: Played for laughs in "The Painting" when Principal Brown tells her to relax and stop working so hard for Anais's sake. But she's so used to it that she can't relax and does her household chores anyway, and then proceeds to trash the house on purpose to give herself more "work".
* WouldHurtAChild: When Leslie and Alan are [[ItMakesSenseInContext amongst the group of cannibals trying to eat her family]], Nicole ''bites off'' part of Leslie's face before swinging him by the neck like a flail and pops Alan ([[FingerpokeOfDoom by blowing on him]]).

!!Richard Watterson
-->Voiced by Dan Russell

Gumball's father and Nicole's [[AmazingTechnicolorWildlife pink]] [[FunnyAnimal rabbit]] husband. Richard is very immature for his age and hates to have any sort of responsibility. He is also quite lackadaisical and sleeps frequently. As a result, Nicole is usually forced to be the parent to their children, but she's not home a lot, so Richard's often the only one available.

* {{Acrofatic}}: He holds up surprisingly well in hand to hand combat against [[{{Badass}} Nicole]] and was able to keep up with her running until she jump between some buildings.
* AdultsAreUseless: Richard practically ''lives'' this trope.
* {{Amazingly Embarrassing Parent|s}}: In "The Hero", Gumball and Darwin fail to come up with something good for their dad and settles on embarassing moments. Unknown to them at the time, Richard overhears the conversation and leaves depressed.
* BadassDriver: While his [[LiteralGenie religious adherence to the GPS]] is quite destructive, it did let him drive across the entire town and miles into the countryside in a couple minutes.
* BadassMustache: He can [[RapidHairGrowth grow a handlebar mustache]] and retract it back into his face at will.
* BecauseDestinySaysSo: His getting a job almost causes the apocalypse.
* BigEater: The man knows how to put food away.
-->'''Richard:''' Eat 100 hotdogs in under a minute. Ha! That's not a dare. That's Tuesday.
** In one episode ("The Prank"), Richard is listening to an audio tape. The tape informs him of its duration so he decides to get some snacks to partake in while listening (this is when Gumball and Darwin spring their prank by switching the tape with one of their own that commands him to do goofy things) and calculates how much food he'll need for the length of the tape. When he returns, however, he's empty-handed because he ''ate everything he was going to eat during the tape on the way back''. He makes a self-note to also include calculations for the return trip for the future.
* BrilliantButLazy: Most often Brilliant At Being Lazy.
* BumblingDad: Like you wouldn't believe...
* CallingYourAttacks: "[[Recap/TheAmazingWorldOfGumballS3E4TheJoy WONDER HUG!]]"
* ChildhoodFriendRomance: He's known his wife, Nicole, since they were Gumball's age.
* {{Cloudcuckoolander}}: He has his odd moments.
* CrouchingMoronHiddenBadass: He can be very crafty when he wants to, such as tricking Gumball and Darwin into doing his chores in 'The Laziest'.
* DisappearedDad: Richard's father was never mentioned until "The Man". [[spoiler:His father left him and Jojo when he went out to get milk ''42 years ago'' and never came back. Richard deep down knew this, but he was in denial about it, which explains his hostile treatment to Jojo's boyfriend because he was afraid of losing her.]]
* TheDitz[=/=]FatIdiot: It's easier to count examples of when he doesn't act like one.
* DrivesLikeCrazy: He follows his GPS without ever paying attention to the road, including the direction he's facing. When he was high on anesthetics he crashed in several cars and parked in a swimming pool; Gumball considered that an ''improvement''.
* FanDisservice: He's frequently shirtless or even in only his underwater, showing off his fat, saggy man boobs.
* FatSlob: He's very fat, leaves trash on the coffee table, and frequently lays around the house with his pants unzipped or not on.
* FreudianExcuse: His laziness and stupidity is the result of his mother completely sheltering him his entire life and never letting him learn to do anything for himself. His mother's parenting style was to make him (and as she tried with her grandkids), scared of everything.
* HairRaisingHare: Richard is adorably stupid most of the time, but pulls off a pretty good NightmareFace when he's the target of the episode's SanitySlippage. The dude is on the series' NightmareFuel page [[BewareTheSillyOnes for a reason.]]
* HardHead: He can take quite a lot of cranial damage, sometimes headbutting objects and destroying them.
-->'''Doctor:''' You are very lucky Mr. Watterson, it appears your skull is so thick you were able to survive a half a ton of tiles and a satellite dish falling on your head. \\
'''Nicole:''' Is he going to be OK, doctor? \\\
'''Doctor:''' Apart from being [[TooDumbToLive living proof that we're doomed as a species]], he's fine,
* TheHedonist: One episode has him basically calling himself this when Gumball and Darwin ask about the meaning of life.
-->'''Richard:''' The meaning of life? Well, I've dedicated my life to the indulgence of the senses. A feeling of total satisfaction and pleasure is the highest form of existence. \\
'''Gumball:''' That just sounds like stuffing your face.\\
'''Richard:''' [[BluntYes Yeah]], well philosophically.
* HouseHusband: Richard is home all day because he has no job, though he usually doesn't do his share of the chores either. When he finally gets a job, [[spoiler:it nearly destroys the Universe.]] Nicole being at work means he's often the only one watching the kids (even if he's not as good at it), with the "The Hero" implying they spent most of their time when they were younger with Richard, but at this point the kids are generally better at taking care of themselves.
* HugeGuyTinyGirl: He's something like half a head taller than Nicole and several times as large.
* InterspeciesRomance: With Nicole.
* LaboriousLaziness: Richard is a master at this. He knows how to get food from the kitchen himself ''without leaving the couch'' and spent the a day tricking his kids into doing a few minutes of chores.
* LargeHam: Richard is very prone to emotional outbursts.
-->''It's because of you I'm mortal!'' (runs away crying)
* LazyBum[=/=]LazyHusband: Laziest man in Elmore since 1983.
* LethalChef: The cupcakes he made in "The Hero" are literally rock hard--he may have mixed cement into them. Other times, he's shown be able to make food that is edible, but often "lethal" [[NutritionalNightmare in a different manner]] (such as the sluzzlewurst, which had so much fat in it that it makes you sweat butter).
* ManChild: He literally acts the exact same way as he did when he was a kid.
* MasculineGirlFeminineBoy: Feminine Boy to Nicole's Masculine Girl.
* MikeNelsonDestroyerOfWorlds: [[spoiler:He almost destroyed the Universe by [[ItMakesSenseInContext delivering a pizza]].]]
* MoralMyopia: He's repeatedly expressed that bad things are only funny when they happen to someone else.
* [[MsRedInk Mr. Red Ink]]: The Watterson's financial problems are not helped by Richard spending money on dumb objects he sees on the internet (the Electro-Fat workout device and a bunch of hormonal supplements), terrible investments ([[spoiler:he spent ''most of the family's saving'' to buy a star right after Gumball was born]]), or just by accident (he doesn't understand that money from an ATM withdrawal comes from his own account).
* OneOfTheKids: An upside to Richard's immaturity is that his kids usually enjoy spending time with him more than their mom, who they usually find boring to hang around with (when she isn't being scary).
* PapaWolf: In "The Hero", he gets to prove himself as the hero to sons by saving them from a trash compactor (eventually).
* ShipperOnDeck: After taking Gumball to a party with Tina as his date, he comes back to see Gumball with Penny, then comments that "I like the new one better."
* ShirtlessScene: Prone to this.
* TheSlacker: A rare version that has children.
* {{Sleepyhead}}: Most commonly seen sleeping on the couch.
* StoutStrength: Richard apparently has some serious muscle under all that fat: in "The Prank" he was able to run through multiple walls and in "The Remote" he effortlessly rips the car door off to get to Nicole.
* StrawLoser: Gumball and Darwin actually look like rather intelligent and diligent beings compared to their father. Granted it almost reverses into being a gift for Richard since he's hopeless enough that people just give up trying to [[IdiotHoudini place any responsibilities onto him]].
* TrademarkFavoriteFood: Sausages, [[ apparently]].
* TooDumbToLive: Thanks to his mom, he's so bad at handling anything that the simplest of tasks can turn life-threatening.
* {{Tuckerization}}: Named after Ben Bocquelet's father.
* UglyGuyHotWife: An overweight, slob of an idiot. Married to an adorable cat lady.
* WackyParentSeriousChild: The wacky parent to Anais' serious child.
* WalkingTechbane: Judging from how automatic doors, elevators, and self-checkout scanners treat him.
* WellDoneDadGuy: In "The Hero" he shows he cares a lot about how much his kids think of him, getting very depressed when Darwin and Gumball call him embarrassing.
* WholesomeCrossdresser: Richard was shown wearing woman's clothing on two occasions and has zero qualms with it.
* WithGreatPowerComesGreatInsanity: Parodied in ''The Wand''. He ''thinks'' he has Power, when it's actually Gumball and Darwin moving along with it so he won't have his childhood dreams crushed. They eventually have enough since it goes overboard.
-->'''Gumball''': [[LampshadeHanging Don't you see what you have become?!]]

A ferocious [[TurtlePower turtle]] that Richard bought from a van shop, thinking it was a dog.

* AxCrazy: His entire existence is biting. He eats for strength to bite. He reproduces to have more turtles who can bite.
* {{Badass}}: It's basically [[Film/TheTerminator the T-800]] in turtle form.
* TheDreaded: The Wattersons are terrified of it. Gumball especially, who calls it [[MadeOfEvil evil incarnate]] and has theorized that it eats [[YourSoulIsMine souls]] and [[EmotionEater misery.]]
* ForTheEvulz: We get a first person sample of his "thought process":
-->'''Turtle:''' Bite! Bite! Bite! Need food for strength to bite! Bite! Bite! Make little turtles to bite even more!
* LongNeck: It can extend its neck something like a foot out of its shell.
* MightyGlacier: On one hand, it has NighInvulnerability. On the other hand, it's a turtle.
* NighInvulnerability: One drop of water let it came back to life from a desiccated husk, then it got hit by a car--the car was totaled, the turtle didn't even budge. When the "Awesome Store" (a van that sold a wide array of things) exploded in a giant fireball, he walked out of the flames completely unharmed.
* NoNameGiven: The Watterson's never gave it a name; they're too busy being terrified by it. When giving it a PrematureEulogy, Darwin simply calls it "evil turtle" [[ADogNamedDog as if that was its name]].
* PintsizedPowerhouse: Its size doesn't keep it from pulling around full-sized people, though it does make it easy to pick it up.
* ReptilesAreAbhorrent: Unlike most terrapins in fiction, played ''very'' straight.
* SealedEvilInACan: Since the turtle is basically invincible, its pen in the Watterson's house is essentially a way to contain it.
* SeldomSeenSpecies: A soft-shell turtle. Quite a few viewers [[AluminumChristmasTrees didn't know there are turtles that look like that.]] WordOfGod [[ specifically called it]] a "Trionyx", which implies it's an [[ African softshell turtle]].
* WeaksauceWeakness: Strong as it is, the turtle's limbs are still very short. If it's picked up by the shell, it won't be able to reach anything and it is unable to climb out of small containers like a terrarium.

[[folder:Students of Elmore Junior High]]
-->Voiced by Rupert Degas (season 1) & Hugo Harold-Harrison (season 2 onward)

A [[AnimateInanimateObject balloon with a face drawn on it]] and a sickeningly nice person. He's [[InterspeciesRomance romantically interested]] in Carmen, which has rather obvious problems.

* AllBalloonsHaveHelium: He can be re-inflated with a person's breath but still keep floating afterward.
* ApologizesALot: In "The Voice" he even apologizes for making someone feel they need to apologize, and continues to apologize until Gumball pops him to make him stop.
* BerserkButton: Gumball finally managed to find something that irritated Alan in "The Saint": the sound people make when they drag their feet on linoleum. [[spoiler:Actually, that was just a lie just so Gumball would feel better.]]
* {{Bishonen}}: His face looks a LOT different in photos than it does in real life. His ''[[BeautyMark mole]]'' is even beautiful.
--> '''Gumball:''' (Trying to blow Alan away) It's bad enough-[blow]-that you're a million times prettier than I am!-[blow]-I don't need you to rub it in my face-[blow]-on how mature and deep you are! [blow]
* [[BizarreAlienBiology Bizarre Object Biology]]: Gumball refers to him as a "biological mystery" when he couldn't tell Alan was crying, but Alan explains:
-->'''Alan:''' Air comes in the knot, air comes out the knot.\\
'''Gumball:''' Hmm, hmm... What about the spaghetti, though?\\
'''Alan:''' Spaghetti goes in, [[NoConservationOfEnergy turns into air]], comes back out.\\
'''Gumball:''' (beat) [[ToiletHumor So technically you weren't only crying just now.]]
* CharacterizationMarchesOn: In his few speaking appearances in the first season, he didn't seem particularly nice to anyone.
* FatalAttraction: Alan and Carmen are passionately in love with one another, but because Alan is a balloon and Carmen is a cactus, their relationship is impossible.
* FlyingFace: Alan is just a balloon with a face drawn on it. His lack of limbs is a frequent frustration of his.
* GoodCannotComprehendEvil: Gumball does a bunch of horrible things to Alan in "The Saint" (including framing him for cheating on Carmen and having his parents [[ItMakesSenseInContext tortured by a clown]]) all for the sake of trying to upset. Alan doesn't ''just'' [[TurnTheOtherCheek forgive him immediately]], he views them in such a ridiculously optimistic way as to believe Gumball never did anything bad.
* HeliumSpeech: Justified, as he's a [[AnimateInanimateObject balloon]].
* IncorruptiblePurePureness[=/=]ParodySue: Is ludicrously good and perfect - a PuritySue parody. Gumball spent an entire episode ("The Saint") trying to make him angry. [[spoiler:He completely failed.]]
* InterspeciesRomance: Alan (male balloon) is madly in love with Carmen (female cactus).
* NiceGuy: So nice, that it makes Gumball (and everyone else) ''sick''.
* NotSoAboveItAll: In "The Storm," after Gumball interrupts his speech to Masami for the third time in a row, he breaks his usual behavior to tell him '''''"Just shut-up, O.K.!!!"''''' Alan was also seen as one of the members of Mr. Small's apocalyptic tribe about to cannibalize The Wattersons in "The Pizza."
* RunningGag: He has no hands!
* SickeninglySweethearts: In "The Storm", he is sickeningly sweet with Carmen, much to their classmates' disgust.
* SkintoneSclerae: As his face is drawn on only in black, his eyes lack any coloration, fitting this trope as much as you can consider any of his body to be "skin".
* TertiarySexualCharacteristics: While he's a boy, [[InvertedTrope he has obvious eyelashes that makes him appear to be a girl]].
* TheyKilledKennyAgain: He's been popped on multiple occasions.
* TinyGuyHugeGirl: He's not even half Carmen's size.

-->Voiced by Lewis [=MacLeod=] (season 1)

A [[AnthropomorphicFood piece of toast]] subject to endless and fatal misfortunes.

* AccessoryWearingCartoonAnimal: He wears only shoes.
* AnimalsHateHim: Ducks and other birds don't hate him, but they do find him ''delicious''.
* BlackBeadEyes
* {{Cephalothorax}}
* TheChewToy: Dies frequently, sometimes by literally being chewed on.
* TheDitz: He was one of the contestants in the dumb race and thought a mirror could talk. It's possible some or all of Anton's memories don't pass on to the next clone when he dies, and thus he can't learn anything because he's always dying--or him already being that stupid is why no one notices him forgetting so much.
* GangOfBullies: The website described him as a member of Tina and Jamie's gang, whether he wanted to be or not, but this was almost never shown in the actual show.
* MadeOfPlasticine: One of the reasons he dies so easily. He is just as tough as you would expect a piece of toast to be.
* TheyKilledKennyAgain: He's been eaten (not even [[JustEatHim whole]], actually torn to piece and eaten) several times now. "The Recipe" shows that he's been killed several times [[note]](besides being eaten by birds, Anton has been turned to mush in the school swimming pool, crushed by a bowling ball, had a heart attack while watching a screamer viral video, eaten by Tobias, blown up in chemistry class, put through a paper shredder, blown up in music class from playing a slide whistle, hit in the face with a baseball, slammed between a door frame, and crushed by Tina Rex's foot)[[/note]] and each time, [[ExpendableClone his parents clone him.]] After a montage of his deaths in the same episode, Darwin suggests that they go find out how he keeps coming back by going to his house, because this was getting them nowhere.
-->'''Darwin''': Maybe we should just ask him. \\
'''Gumball:''' Maybe you should've said that before we iced him fifty times in a row.
* TooDumbToLive: Many of his [[TheyKilledKennyAgain frequent deaths]] are a direct result of a lack of basic self-preservation skills. The gym coach once told him to jump into the school pool. By all rights he should know that, as a piece of toast, he'll turn into mush if he gets wet, [[ForgotICouldntSwim yet he jumps in without a second thought.]]

!!Banana Joe
-->Voiced by Rupert Degas (season 1) & Hugo Harold-Harrison (season 2 onward)

A constantly jovial and clownish [[AnthropomorphicFood banana.]]

* AbnormalLimbRotationRange: A strange example; his arms, legs, and facial features have a normal range of movement compared to each other, but his banana "body" freely flips around without any horizontal fixed relation to the rest of him.
* AnnoyingLaugh: He frequently makes a harsh "He-he!" sounding laugh in the first season. His laughter from the second season on isn't nearly as loud or annoying.
* {{Autocannibalism}}: It's mentioned in "The Promise" that the last time he went camping, he was left alone in the woods and had to use his banana skin and eat parts of himself to survive. That, and the winter storm that came when he walked home, is why he has no feet.
* BerserkButton: Do not ruin his family's pen. Or his school picture.
* BewareTheNiceOnes: Subverted, as even if you provoke his wrath he's too tiny, weak, and incompetent to be a threat to anyone.
* CatchPhrase: "I'm a banana."
* CharacterizationMarchesOn: His characterization in the first season was all over the place: sometimes he was kind of a jerk or even [[AxCrazy utterly psychotic]] and other times he was cheerful to the point where he literally could not stop making jokes constantly. From the second season on, [[TookALevelInKindness he's a lot nicer]], but still capable of being pushed too far, and is capable of being serious for a minute. He also didn't strip off his peel as much in the earlier episodes.
* ClassClown: Constantly making jokes, but no one really thinks he's funny.
* JigglePhysics: His eyes in the first season were literal googly eyes whose pupils shook around as he moved.
* NiceGuy: He forgives Gumball and Darwin for their numerous and unwarranted attempts at violent revenge "The Banana" and their horrible negligence in "The Promise".
* NoBrows: He has no eyebrows in the first season.
* PlantPerson: A walking, talking banana.
* PungeonMaster: Most of his jokes consists of painful puns.
* SpeciesSurname: Although "Banana" is the first part of his name, it seems to be his surname anyway given he's stated to be from the "Banana family".

-->Voiced by Kerry Shale

A socially-ignorant [[RobotKid robot]] who wishes the other students would be his friends--when he's not busy being condescending toward them.

* AIIsACrapshoot: In "The Robot", he decides to steal Gumball's life. Conversely, turning super-obedient in "The Bet" made him a vicious LiteralGenie. He tends to lose control and try to kill Gumball and Darwin with [[AxeCrazy startling regularity]].
* CuteMachines: Appearance-wise, he is quite cute. In terms of personality, he can vary from [[{{Adorkable}} endearing awkward]] to [[InsufferableGenius intolerably smug]] or even [[AIIsACrapshoot frighteningly amoral]].
* CyberCyclops: He has a single, off-center eye.
* DoAnythingRobot: Besides a large variety of weapons [[SuperPoweredRobotMeterMaids of questionable necessity]] and [[AxesAtSchool legality]], Bobert has a large number of other functions like video recording, vocal imitation, and spontaneously growing an extendable fan.
* DoesNotKnowHisOwnStrength: Gumball learns this the hard way when they play punchies.
* IJustWantToBeYou: He tries [[IJustWantToHaveFriends learn how to make friends]] by copying Gumball in "The Robot", but instead decides to become him exactly, [[KillAndReplace steal his life, and try to get rid of the real one.]]
* InsufferableGenius: He's downright condescending towards his classmates despite wanting to be friends with them.
* NoMouth: He doesn't have a mouth, though when he speaks two blacks bars on his face, which are possibly a speaker, light up.
* NukeEm: Is capable of this in his fighting robot form. Hiding behind a nearby chair is enough protection though.
* PintSizedPowerhouse: Even at normal size he can easily [[PunchedAcrossTheRoom punch someone across a room.]]
* TeachersPet: Considers himself to be this.
* TinMan: When some kids says he has no emotions, he seems to agree, despite emoting quite regularly.
* TransformingMecha: Capable of [[TelescopingRobot increasing his size]] into a fighting robot about 5 meters tall.

-->Voiced by Jessica [=McDonald=] (Season 1); Alix Wilton Regan (Season 2 onward)

A [[AnimateInanimateObject cactus]]. She's [[InterspeciesRomance romantically interested]] in Alan, which has rather obvious problems.

* BlackBeadEyes
* FatalAttraction: With Alan, as previously stated.
* InterspeciesRomance: Carmen (female cactus) is madly in love with Alan (male balloon).
* PlantPerson: A walking, talking cactus.
* SickeninglySweethearts: In "The Storm", she is sickeningly sweet with Alan much to their classmates' disgust.
* SingleWomanSeeksGoodMan: Even if the others find Alan's {{nice guy}} personality incredibly sappy and sickening, Carmen wouldn't have him any other way.
* [[TheSmartGuy The Smart Girl]]: Carmen is one of the smartest girls in school according to the website.
* TertiarySexualCharacteristics: Averted. She has no distinguished trait that shows she's female.
* TinyGuyHugeGirl: She's the same size or smaller than most students of Elmore, but certainly a lot larger than Alan.
* UnableToCry: She can cry, but there aren't any tears [[FurryReminder because her body is meant to retain moisture.]]

!!Carrie Kruger
-->Voiced by Jessica [=McDonald=]

An emo ghost girl, though she's more Goth than emo.

* AccessoryWearingCartoonAnimal: The only part of her body that is visibly clothing is her hair bow.
* AllGirlsLikePonies: Despite everyone else finding ''[[MyLittlePhony A Pony's Tail]]'' impossibly terrible, Carrie loved it, completely shocking herself.
* AllWomenLoveShoes: {{Lampshade|Hanging}}d during "The Flower"
-->'''Jealousy:''' How many pairs of shoes do you need!? You don't even have feet!
* BigEater: She hasn't eaten since she became a ghost, so when she possesses someone's body she'll eat until it ''passes out''.
* BlackBeadEyes
* CuteGhostGirl: Darwin sure seems to think so when he kissed her.
* DeadpanSnarker: Carrie is almost always deadpan and occasionally snarks. She once has her face sucked into a vacuum and distorted, then replied with a flat "Gross."
* DemonicPossession: She can possess someone's body by [[OrificeInvasion flying into their mouth and down their throat.]]
* [[EmoTeen Emo Tween]]: Carrie is described as emo, though she has a lot of {{goth}} elements like her occult room decorations and loving the smell of death.
* FriendlyGhost: Despite her morose demeanor, Carrie is good friends with at least some of her classmates, getting very concerned when Darwin and Gumball are turned into ghosts and upset when it seemed they were stuck in the underworld.
* HairDecorations: Has a bow on the side of her head.
* TheHedonist: It's been so long since she's been able to do things like eating, that when she has a body, she'll immediately starting [[BigEater binge-eating]] [[ExtremeOmnivore absolutely anything]] (except, apparently, pickles).
* HeroicBastard[=/=]NomDeMom: When Carrie says her dad's full name, it ends with "Lokowitchki", not "Kruger". Whether this is because her parents never married or for some other reason isn't specified, though in the case of the former it's likely because [[spoiler:her dad turned into the Snatcher before they could.]]
* TheMirrorShowsYourTrueSelf: [[RuleOfFunny Sometimes]] Carrie lacks a reflection or doesn't show up in film (which involves projecting reflections), like when Mr. Small took her class photo.
-->''"I'm not paying for that."''
* PickyEater: When Carrie takes over Gumball's body and starts binge-eating everything in sight, she takes a moment to remove the pickle slice from a hamburger before devouring the whole combo meal.
* LuminescentBlush: She blushes when Darwin kissed her in "Halloween" and in "The Coach" when she said that all the work-out made her feel alive.
* NonHumanHumanoidHybrid: [[spoiler:Carrie's mother was a ghost of unknown species. Her father was a mortal CartoonCreature that looked mostly human.]]
* OurGhostsAreDifferent: In "Halloween" she claims she was ''[[ItRunsOnNonsensoleum born]]'' a ghost[[note]]Neither Gumball or Darwin could guess how that works.[[/note]] which means she stays in the living world and can be seen by anyone, even though other ghost can only come there on Halloween and are InvisibleToNormals. "The Mirror" seemingly provides an actual explanation to this: [[spoiler:Her mom was a ghost and her dad a mortal who used magic to be able to touch her, apparently making her a sort of [[NonHumanHumanoidHybrid half-mortal hybrid]].]] Both of these, however, came after her [[MultipleChoicePast mentioning that she used to have a body.]]
* PeekABangs: Much like Gumball's whiskers, subject to FashionableAsymmetry and AmbidextrousSprite.
* PerpetualFrowner: Usually has a morose expression on her face, though she's sported a [[ScaryTeeth sharp-toothed]] grin a few times.
* ShoutOut: Her name is likely inspired by two famous horror characters: [[Literature/{{Carrie}} Carrie White]] and [[Franchise/ANightmareOnElmStreet Freddy Krueger]]

-->Voiced by Rupert Degas (Season 1) & Max Cazier (Season 2 onward)

A [[AnimateInanimateObject blob of red clay]] and a compulsive liar, animated in claymation.

* BadLiar[=/=]ConsummateLiar: He's able to lie constantly with complete conviction because [[BelievingTheirOwnLies he convinces himself at the same time]], but people rarely fall for them because they're so ridiculous. Seemingly the only one who believes him is Tobias.
* {{Claymation}}
* IRejectYourReality: In "The Move" he admits he lies so much because he thinks his actual life is boring.
* TheMunchausen: He constantly tells improbably stories about himself and his family.
* NoBrows: His design in the first season lacked eyebrows. Adding them was the most noticeable difference in his second season redesign.
* PoisonousFriend: In "The Skull," Clayton constantly includes Darwin and Gumball in his lies and [[ToxicFriendInfluence causes them to start lying the same way themselves]]. To their credit, Gumball and Darwin figure out he's a bad influence on them almost right away and break it off with him... only for him to attempt to lie his way back into their good graces.
* PunnyName: Clay(ton)
* VoluntaryShapeshifting: He can change into a lot of shapes, including other people (and fake their voices as well). Justified, in that he's a ball of clay and clay can be molded into whatever you want it to be, even though it's still clay, no matter what (which [[FridgeBrilliance also explains why a ball of clay would be a compulsive liar]]).

!!Detention Kids
-->Voiced by Hugo Harold-Harrison (Bomb Guy)

A group of students at Elmore Junior High mostly seen in detention. Includes a [[AnimateInanimateObject a guy with a bomb for a head, a human hand, a giant teddy bear]], [[AnthropomorphicFood a rotten cupcake]], and [[FunnyAnimal a rat]].

* ActionBomb: The most prominent one has a bomb for a head. Making him mad causes him to explode, incapacitating him while reducing his head to a much smaller size.
* AnimatedTattoo: The hand has a tattoo of a skull wearing a crown which acts as his face, being capable of moving around and talking.
* DudeLooksLikeALady: The cupcake guy's pink coloration, mouth that looks like it has lipstick on it, and heeled boots cause Darwin and Gumball to mistake him for a (very ugly) girl.
* HelpingHands: One is a giant human hand and wrist [[TattooedCrook covered in tattoos]], one of which acts as his face.
* KillerTeddyBear: One of them is a giant pink teddy bear who comes off as harmless at first until he bashes Darwin and Gumball's heads together and [[VisualPun pops the cupcake guy's cherry]].
* VagueAge: They're at most a grade older than Darwin or Gumball, but mostly seem like they're well into their teens or even adults. It's possible some of them have been held back ''a lot''.
* YouDirtyRat: Their smallest member is a rat with a [[GoodScarsEvilScars facial scar]] that always wears a hoodie.

!!The Eggheads
-->Voiced by Kerry Shale, Rupert Degas (Season 1), Hugo Harold-Harrison (Season 2 onward)

A pair of intellectual, nerdy [[AnthropomorphicFood eggs]].

* AstonishinglyAppropriateAppearance: They're "eggheads" both literally and figuratively.
* BigOlEyebrows: Their eyebrows are very thick and [[BigOlUnibrow there's a good bit of hair inbetween]].
* {{Cephalothorax}}
* TheDividual: They're almost always shown together and acting in unison.
* LongPants: Their pants and shoes appear as a single black-painted section of their body.
* {{Nerd}}: Both have nasally voices and always talk about academics or science fiction. One has NerdGlasses and braces, the other has a face covered in acne.
* NoNameGiven: They're never referred to by name; "Egghead" is just a FanNickname. On his Formspring, one of the writers came up with the names "Frank" and "Beans".

!!Green Bear Guy

What appears to be a [[CartoonCreature green teddy bear]] or a [[AnthropomorphicFood giant sentient Gummy Bear]], as well as a background character who wants to take the stage.


* AscendedExtra: Somewhat. He was a background character until leading a musical number and a HostileShowTakeover in "The Extras". Then he sank back into the background.
* HiddenDepths: He's quite a good singer.
* RecurringExtra: Usually seen in the background of the Elmore Junior High cafeteria.
* VagueAge: He looks and sounds like an adult, yet he's usually seen in a middle school cafeteria.

!!Hot Dog Guy
-->Voiced by Adam Long

A [[AnthropomorphicFood living hot dog]] who's another background character.


* AscendedExtra: He was a background character since almost the show's beginning, then had a speaking role in "The Castle" and joined in the HostileShowTakeover in "The Extras".
* CoolShades: He is never seen without his shades.
* OurNudityIsDifferent: He considers his hot dog bun clothing, even though it's pointed out it only covers the sides of his body.
* RecurringExtra: Usually seen in the background of the Elmore Junior High cafeteria.
* VagueAge: Like the Green Bear Guy, he's always seen in a middle school cafeteria, but everything else indicates he's an adult.

!!Hector Jötunheim
-->Voiced by Kerry Shale

A giant covered in colorful fur.


* ArtEvolution: Sorta. In Season 1, originally the only thing that can be seen of him was usually just his feet due to him being too big to fit in the screen. Other body parts of his would occasionally be seen also, but he never appeared in full body view. In Season 2, he still retains his original depiction but from time to time, his entire body would be shown in full view, most notably in "The Colossus".
* TheFaceless: His face was always offscreen in season one. From season two onward his head is visible, but [[BlindingBangs his fur covers all of his facial figures]]. The two exceptions to this so far are a view of his ear when Gumball plays music into it in "The Colossus" and a brief shot in season three's "The Butterfly" showing Hector's mouth and nostrils when he falls down.
* GentleGiant: [[EnforcedTrope Enforced]], because if he wasn't, he'd quickly wreck up the whole town. [[SubvertedTrope In practice]], everyone trying to avoid upsetting him [[HairTriggerTemper has left him rather thin-skinned and easily excited.]] In fact, according to a FreezeFrameBonus on "The Apology," one of the offenses that warrants a suspension from school is "upsetting Hector" (which also counts as "destruction of property").
-->'''Gumball:''' You're not boring, dude. You're nuts.
* MeaningfulName: His last name refers to Jötunheimr, the land of giants from Norse mythology. His first name is from the prefix "hecto-", which is a factor of 100.
* MulticoloredHair: It gradually changes color as you go up his body from purple, to orange, to reddish pink.
* OurGiantsAreBigger: He's taller than the building for the school he attends, and thus is only seen hanging around the playground. Judging by a comment he made about his dad on "The Hero" (he mentions his father's so big that three mountain climbers got stuck in his belly button), '''''he's not even fully grown yet'''''!

-->Voiced by Rupert Degas (season 1) & Hugo Harold-Harrison (season 2 onward)

A [[AnthropomorphicFood potato]] from a farm on the outskirts of Elmore.

* AmericanAccents: Appalachian.
* BlackBeadEyes
* {{Cephalothorax}}
* CountryMouse: He commutes to school from a farm and doesn't know what a TV is.
* DisneyDeath: When he appears to die in "The Bumpkin", his parents bury him, and after a short time in the "dirt bath" he pops out good as new.
* GoodOlBoy: He's a jovial hick.
* MeaningfulName: He's a potato named after a state famous for producing potatoes.
* PlantPerson: A walking, talking potato.

-->Voiced by Jessica [=McDonald=] (seasons 1-2) & Maria Teresa Creasey (season 3 onward)

A schoolyard bully that [[CartoonCreature vaguely resembles a minotaur]], animated in 3D.

* BarbaricBully: You don't get much more barbaric than tearing off someone's arm and spitting it at them.
* BlindingBangs: She has these now in season 3.
* CartoonCreature[=/=]MixAndMatchCritters: Has horns like a bull, but a lion's tail and the body of a human. Darwin insults her by claiming she's a "half-cow, half-troglodyte". To make it weirder, her mother is [[spoiler:a giant red cube]] and her father is probably the same species as her but with a pointy hair or hat with straight horns and without a tail.
-->'''Gumball:''' Coach saw what we were all too blind to see. That you're really a sweet, kind... orange thing with, uh, a hat or a wig or some kind of a helmet and horns that we're proud to call our friend.
* EvenBadWomenLoveTheirMamas: As mean as she is, she immediately toes the line anytime her mother ([[spoiler:the Coach]]) is around.
* EvenEvilHasStandards: She's no doubt a bully, but she was just as upset as the others when they thought Gumball kissed Carmen in front of Alan.
* FullyDressedCartoonAnimal: Although she's easy to mistake as a HalfDressedCartoonAnimal because her shirt is so similar to her skin in color.
* InformedAbility: The characters page on the official website describes her as being a bully because Ms. Simian [[HeldBackInSchool held her back a year]] so she developed an extreme resentment for authority and her new classmates, which was never mentioned in the show. It also says she is Tina's sidekick, but the two were only shown working together once in "The Fight" where Jamie's presence was not commented upon.
* PerpetualFrowner: Her default facial expression in season three is a frown. Before that she was, ironically, [[PerpetualSmiler almost always smiling]].
* [[RedheadedBully Redheaded]] [[IncrediblyLamePun Bull]][[RedheadedBully y]]: Her worst acts of bullying include feeding Anton (a piece of toast) to ducks, ripping Teri's (a paper doll) leg off and spitting it back at her ''a la'' a spitball, and turning Sarah and Banana Joe into an ice cream sundae while Sarah staggers around with no head and Joe screams.
* SillyWalk: She doesn't have knees, so she basically goose-steps when she walks.
* TheSociopath: She is a very sadistic and ruthless bully.

-->'''Voiced by:''' Beatbox Hobbit (in music mode), Hugo Harold-Harrison (in voice mode)

A short humanoid with a boombox for a head.

* BigOlUnibrow: His buttons visually invoke a unibrow, but they do not [[ExpressiveMask move with his facial expressions]]. [[ArtEvolution In season two]] he [[SuddenAnatomy gains regular eyebrows]] when necessary.
* ForeignExchangeStudent: He's from some country in a continent called Boomboxembourg.
* FullyDressedCartoonAnimal
* LineBoil: Very subdued compared to most examples, but his outline shakes slightly.
* TheUnintelligible: He speaks (and ''writes'') in beat box and as a foreign exchange student everyone assumes he's speaking a foreign language. He actually ''knows'' how to speak English fine, but when a switch on his head is in the wrong position he can only play music instead of talking. Since he can't reach the switch or tell anyone else, it's been stuck like that for over two years.

-->Voiced by Kerry Shale

A sensitive [[AnimateInanimateObject flower]].

* AmbiguouslyGay: Mostly blatantly shown in "The Mustache", when Gumball's butt suddenly becomes incredibly muscular and Leslie just stares. In "The Pressure", he's shown hanging out with a group of girls throughout the episode, with his presence never being noted; the other male characters mention him when talking about "the girls", and wordlessly joins in their expressions of interest in the idea of watching or kissing boys.
-->'''Leslie:''' There's a lot of things you don't know about me, Gumball.
* GenderBlenderName: Male, despite the name and appearance.
* {{Malaproper}}: He keeps mispronouncing things in "The Words", much to Darwin's annoyance.
* NiceGuy: He was very willing to forgive and make friends with Gumball after his insane feats of jealousy in "The Flower".
* PlantPerson: A walking, talking flower.
* RealMenWearPink: Leslie has pink flower petals and is the only male cheerleader of his school's team.
* StrawVegetarian: {{Inverted|Trope}}; as a plant, he refuses to eat vegetables and tries to bug Penny into ''only'' eating meat.

-->Voiced by Jessica [=McDonald=]

A [[AnimateInanimateObject white cloud]] obsessed with popularity and generally having her way.

* BlackBeadEyes: Her eyes actually appear to be a pair of holes in her face, but give this appearance.
* AttentionWhore: Masami is always trying to impress the other girls, faking a relationship with Darwin to seem more mature and partially being interested in Alan because she though they'd make a popular couple.
* FlyingFace: She has no limbs, just a face on a cloud.
* GlowingEyesOfDoom: When she's angry, her eyes have an electric glow to them.
* JerkAss: The most consistently bitchy character in the show.
* [[ManipulativeBastard Manipulative Bitch]]: Forces Darwin to be her boyfriend and then fake-cries to make him feel guilty when he tries to break it off then. After Gumball accidentally breaks up Carmen and Alan, she pretends to help them get back together with an OperationJealousy, but she actually wanted to be with Alan and tried to blackmail Gumball into keeping quiet.
* PetTheDog: In "The Tape", she lends her cell phone to Tobias so he can call his mother. She missed the point of his pick-up line, but it ''was'' uncharacteristically nice of her.
* RichBitch: {{Lampshade|Hanging}}d by Darwin in "The Words". One of the lyrics in his song, "What He Thinks About Us," states that Masami only has friends because she's from a rich family.
* SpoiledBrat: Daughter of the rainbow factory owner and has a smug sense of superiority.
* WeatherManipulation: Can pull off minor things like raining and lightning at will, and when she's really angry she can generate a stormy tornado around herself.
* {{Yandere}}: She lies to hook up with Alan in "The Storm" and starts destroying the school when he breaks up with this. She stops once she realizes he's "such a wet cheeseball" and loses interest.

!!Molly Collins
-->Voiced by Jessica [=McDonald=]

A dorky, black, boxy-looking [[FunnyAnimal sauropod]] who mostly appeared in season one. After being absent in season two, she appeared again in "The Void" with an explanation of why she was gone and why no one realized it.

* ChuckCunninghamSyndrome: Disappears entirely from Miss Simian's class without explanation in season two, save for a single cameo in the background of a photo in "The Words".
** TheBusCameBack: Reappears in "The Void." [[spoiler:Apparently the dynamics of the world deemed her too boring so she got sucked into a void full of bad ideas. Darwin, Mr. Small, and Gumball manage to get her out, and she's eventually seen back in the backgrounds again later in the season, even though she doesn't appear in classroom scenes that often]].
* EverythingsBetterWithDinosaurs: A sauropod, although she looks more like a CartoonCreature.
* RetGone: [[spoiler:The reason for her disappearance]].

-->Voiced by Max Cazier

A very-intense spider [[RefugeeFromTVLand from a late 1970s video game]], similar to the aliens from ''Space Invaders''.

* AxCrazy: He could kill you for the slightest offense.
* ChuckCunninghamSyndrome: He hasn't made a proper appearance since "The Tape", which was a Season 2 episode.
* TheDreaded: Gumball lives in fear of the guy when he's near. For good reason.
* FourLeggedInsect: A six-legged spider, but since he's a video game character this was probably an in-universe example caused by sprite limitations.
* HairTriggerTemper: He literally tries to kill Gumball for insulting him. [[ObliviouslyEvil He is not aware this kind of behavior is inappropriate]] because people are too terrified to give an honest answer whenever he asks if he's overreacted.
* MeaningfulName: Ocho is Spanish for Eight, like an 8-bit video game processor, though Ocho is based on [[UsefulNotes/TheGoldenAgeOfVideoGames a graphical style]] that's even older than [[UsefulNotes/The8bitEraOfConsoleVideoGames the games most people think of as "8-bit"]]. Spiders are known to have eight legs, though [[FourLeggedInsect he doesn't]].
* SuddenlyVoiced: He speaks normally in season two.
* TheUnintelligible: Spoke in ArcadeSounds in season one.

!!Penny Fitzgerald
-->Voiced by Teresa Gallagher

A good-natured [[AnimateInanimateObject peanut]] [[MixAndMatchCreatures with antlers.]] [[spoiler:Underneath the peanut shell, she's some sort of ghost-like shapeshifter with antlers.]]

* ArtEvolution: Went from [[ this]] during season 1, to what you see above in season 2 up until the season three episode "The Shell."
* AccessoryWearingCartoonAnimal: Only wears shoes and a sweatband on her arms. [[spoiler:After she literally broke out of her shell and revealed that she's a shape-shifting spirit, she no longer wears any clothing normally, but puts the sweatbands back on (plus a third one on her head) when cheerleading.]]
* BeautifulAllAlong: [[spoiler: In "The Shell", it's shown that Penny is a flying, multicolored creature with wings, who morphs into different shapes depending on her mood. Gumball definitely thinks she looks "extraordinary". Penny wasn't by any means "ugly" before, just decent-looking, compared to the form she was hiding beneath.]]
* BlackBeadEyes: Like Masami, her eyes have the appearance of Black Bead Eyes, but actually seem to be holes in her shell--Gumball once said she looked like a "coconut with holes in it". Given her shell turns out to be removable, it could be considered a form of ExpressiveMask.
* TheCheerleader: She is, technically, a cheerleader. But the malicious version described in this trope is averted.
* InterspeciesRomance: With Gumball.
* InvoluntaryShapeshifter: [[spoiler:Her real form inside her shell. How she looks [[PsychoactivePowers depends upon her self-image]] and possibly other emotions, from a rabbit, to a dragon, to a form that looks somewhat similar to how she was with the shell still on. Being distressed or confused causes her to [[ShapeshifterSwanSong rapidly change between forms]]. She still always [[MorphicResonance has antlers]], though.]]
* LittleMissSnarker: Penny can be amazingly snarky when putting down [[CasanovaWannabe Tobias]].
* MoralityPet: {{Downplayed}}. While Gumball is far from anything evil or even a straight {{Jerkass}}, Penny is probably the only person he's never speaks sarcastically or cynically towards.
* NiceGirl: Popular, cheerleader, and sweet as can be. In "The Bros", she told Gumball she needed space just so he and Darwin can have time to repair their friendship as the latter was very envious about Penny getting attention from him and she doesn't hold a grudge about it since she also cares for Darwin's well-being.
* NotSoAboveItAll: The end of "The Flower" shows she's capable of the same illogical jealously that Gumball had been going through.
* OfficialCouple: with Gumball
* RelationshipUpgrade: [[spoiler:After their BigDamnKiss at the end of "The Shell" she and Gumball are now dating.]]
* TheRunaway: In "The Shell", she decides to run away from home and [[spoiler:go live in the forest, because she believes everyone, even her dad, thinks she's a monster. Gumball convinces her to come back.]]
* ShapeshifterDefaultForm: [[spoiler:It's not clear whether it's a Type A or B, but when she isn't worried about what other people think of her, under her shell she looks similar to how she did with it on, but with red and orange skin, a larger head, [[WingsDoNothing static]] wing-like appendages, and [[PowerpuffGirlHands no hands or feet]].]]
* SingleTargetSexuality: The only person Penny is romantically interested in is Gumball.
* SingleWomanSeeksGoodMan: Penny is romantically interested in the fundamentally good guy, Gumball. [[spoiler:They become an OfficialCouple after Gumball convinces her she's not the monster she thinks she is.]]
** In "The Sweaters", after she finds out that Gumball (along with Darwin) was challenged to a tennis fight with two kids from Richwood High she gave this bit of dialogue:
-->''Gumball! I heard you're gonna sacrifice yourself to save the school. I know it's heroic and selfless and- (looks aside) kind of attractive. ''
** On their [[spoiler:first date in "The Burden"]], Penny also liked Gumball showing his paternal side to the school's pet hamster. Heck, she even called his side ''"attractive"''.
* SmittenTeenageGirl: With Gumball. Technically, Pennny is "tweenage".
* TinyGuyHugeGirl: Penny is always shown as being taller than Gumball, though by how much varies by scene.
* TwiceShy: Her feelings for Gumball are mutual, but both struggle to confess to each other. [[spoiler: As of "The Shell", they're official.]]

-->Voided by Hugo Harold-Harrison

A skinny blue cyclops.

* ArtEvolution: He was CGI in his background appearances in the first season, but in the second season he switches to a 2D design. [[spoiler:In season three's "The Nobody," he returns and is back to being in CGI, but the CGI is more well-done than it was in season one.]]
* AscendedExtra: His first speaking line is mid Season Two, but he appears before that as a background character
* BigBad: Since Rob needed a new place in life and Elmore basically only had room for villains, [[spoiler:he decides to become Gumball and Darwin's ArchNemesis.]]
* BodyHorror: [[spoiler:Escaping from the void]] caused his body to become all [[OminousVisualGlitch glitchy]] and disfigured. Part of his body even displays the void's background pattern.
* ChekhovsGunman: His cameo in "The Void" turns out to be significant in "The Nobody".
* {{Cyclops}}
* FromNobodyToNightmare: After [[spoiler:coming back from the void but not remembering who he is]], Rob literally calls himself "nobody". Darwin and Gumball suggest he strive for a new place in the world as the worst person ever. [[spoiler:Rob then remembers who he is and how they left him behind in the void, and swears to take revenge by destroying everything they care about and taking away everyone they love.]]
* FullyDressedCartoonAnimal
* TheNondescript: After Darwin and Gumball stop talking to him, they immediately forget who he was or that they even met him. It really says a lot about [[WorldOfWeirdness Elmore]] and [[CastOfSnowflakes it inhabitants]] that a ''blue cyclops'' is considered "nondescript".
* HeartwarmingOrphan: [[spoiler: According to "The Nobody":]]
-->[[spoiler:'''Gumball:''' Oh, you know what else is thick? Your mom's chin! \\
'''Rob:''' I don't have a mom.\\
'''Gumball:''' Yeah. I meant your mom's skin. \\
'''Rob:''' I still don't have a mom. ]]
* PutOnABusToHell: He's seen floating around the bad idea dimension in "The Void", indicating he was RetGone. Unlike Molly, Gumball and Darwin do not remember him, so he ends up being left there without comment -- [[spoiler:[[TheBusCameBack until it was revealed]] that he actually broke out of the void and has been living in the Wattersons' basement with no memory of who he was until Gumball and Darwin tell him that he can be their worst enemy.]]
* UnknownRival: Even after he [[spoiler:swears to be Darwin and Gumball's nemesis]], they still ignore him and probably immediately forget about him.
* WalkingSpoiler: The fact that he has any plot significance at all is a rather huge spoiler for "The Nobody" and possibly more.

!!Sarah G. Lato
-->Voiced by Jessica [=McDonald=]

An [[AnthropomorphicFood ice cream scoop in a cone]] who transferred to Elmore Junior High in the second season.

* AscendedExtra: She was a background character until late in season 2.
* BlushSticker: She has oval-shaped ones on her cheeks at all times.
* HeldBackInSchool: Strangely, the school she used to go to is called Richwood ''High'', [[FridgeLogic which would imply her transfer involved going back at least one grade]]. This is probably just an oversight on the writers' part.
* HugeSchoolgirl: With the exception of Tina, she's one of the tallest girls at the school.
* TheMillstone: In "The Sweaters", she keeps pushing for Darwin and Gumball to fight the kids from her old school, [[HypocriticalHumor despite saying they're not to be messed with]], even going behind Gumball and Darwin's backs to provoke them. Given some of the pictures in "The Fan" implied Sarah was stalking Darwin and Gumball even before transferring to Elmore, it's a strong possibility she was solely responsible for Gumball and Darwin's "reputation" at said school that brought the pair in the first place.
-->'''Gumball:''' (watching Sarah hanging around his house) This girl's trouble, man.
* LoonyFan: She's obsessed with following Darwin and Gumball's adventures, sometimes trying to get them into more or fit herself into them.
* LosingYourHead: The ice cream part of her can fall off the cone (as seen in "The Coach" and "The Allergy"), but it doesn't seem to do anything to her. Her body can even move independently, though this is difficult for obvious reasons.
* NewTransferStudent: In "The Sweaters" it's explained she transferred to Elmore Junior High from Richwood High. In "The Fan" she lets it slip that she transferred just to be closer to Darwin and Gumball.
* PunnyName: A gelato (G. Lato) is a frozen Italian dessert that's a lot like ice cream, though Sarah is modeled after American-style ice cream.
* RememberTheNewGuy: Sarah showed up in the background of most of season two, [[InvertedTrope but was introduced in one of the season's last episodes ("The Sweaters") as if she's just transferred then]]. Her one speaking role before that in "The Voice" did show that Darwin and Gumball didn't know her yet.
* SphereEyes
* StalkerWithACrush: Her fascination with Gumball and Darwin goes UpToEleven in "The Fan", including a StalkerShrine and video of her watching them in secret.
* StrawFan: She has a lot of traits of a stereotypical fangirl: she draws [[TerribleArtist very bad]] {{animesque}} fanart and writes overly-dramatic, romantic fanfiction about Gumball, Darwin, [[SelfInsertFic and herself]]. Darwin and Gumball end up humoring her and acting it out to cheer her up (before tearing it to shreds).
* WrongGenreSavvy: Aggressively so. Sarah tends to force the boys into whatever kind of story strikes her fancy that week. She even brings her own soundtrack.

-->Voiced by Aurelie Charbonnier (season one); Fergus Craig (season two), though Charbonnier's chin is still used as the actual puppet

An obnoxious live-action [[CartoonCreature chin puppet]] who can't stop eating and is considered gross and a bit of an outcast.

* {{All Loving Hero}}ine: "Sussie likes everything in the world".
* BigEater: Rarely seen not eating.
* {{Cloudcuckoolander}}: She acts extremely spacey. At one point she held a party and "practiced" welcoming guest by randomly opening the door to greet thin air.
* FatBastard: Less bastard and more just plain annoying and gross.
* FatIdiot: Moreso in season 2.
* FatSlob: Complete with JabbaTableManners.
* FullyDressedCartoonAnimal: Her lower half is shown [[ extremely few times]], but these times show she wears shoes.
* HiddenDepths: In "The Question," she turns out to be more philosophical than she lets out, citing probably the most insightful answer to Gumball and Darwin's question of what's the meaning of life[[note]]that's it's not about the destination; it's about the journey and who you meet along the way and what you decide to do with your life to get the most out of it[[/note]]. She also implies [[SmarterThanYouLook she actually isn't stupid]], she just acts that way because [[ItAmusedMe to her, that's how she enjoys and finds meaning in her life]].
* KindheartedSimpleton: Despite her kookiness, she is (with the exception of Penny), Miss Simian's nicest student.
* ThirdPersonPerson: Bordering on HulkSpeak after her [[TookALevelInDumbass vanishing intelligence]] in season 2.
* VerbalTic: She tends to repeat the last word she hears.

-->Voiced by Teresa Gallagher

A [[AnimateInanimateObject paper cutout]] of a teddy bear girl. Very afraid of germs and catching disease, much to the annoyance of the school nurse.

* BarefootCartoonAnimal[=/=]FullyDressedCartoonAnimal: Her design isn't detailed enough around the feet to tell if she's supposed to be wearing shoes. Technically she isn't wearing ''any'' clothes, just part of her body shaped like a skirt and drawn-on details that indicate clothing.
* BearyFriendly: She's definitely not violent or intimidating (being about as strong as you'd expect a crumpled piece of paper to be) and is on the school's cheer team, though her obsessive, somewhat egocentric behavior gets on people's nerves.
* TheChewToy: She becomes victim to an incredible amount of physical trauma in season three, likely because being made of paper makes it all BloodlessCarnage. This includes having a hole burned into her face, one arm being torn off by Miss Simian during the Joy virus attack, Jamie ripping off one of her legs, chewing it, and spitting it in her face, and being impaled on Carmen's needles.
* FaceDoodling: Does this to herself at times when necessary (e.g. "The Virus", where she draws tears under her eyes to represent crying, and later draws a surgical mask over her mouth) and was seen passed out and drawn on in "The Party." [[JustifiedTrope Her paper body gives her the capability of erasing face doodles quite easily]].
* {{Hypochondria}}: Much to the annoyance of the school nurse.
-->'''Teri:''' I can feel myself getting ill... \\
'''Nurse:''' Hmm, like Monday, when you thought the foam in your mouth was rabies only to discover it was toothpaste? Or Tuesday, when you thought you broke your leg even though you don't have any bones? Or yesterday, when you thought you'd gone deaf because nobody had spoken to you for five minutes.
* IllGirl: Or at least that what she's worried about being.
* MadLibsCatchPhrase: "You do know that [noun] has more germs on it than a toilet seat?"
* MotorMouth: When something cause her to talk about disease, Teri tends to go on a detailed clip without any letting anyone else talk.
* PaperPeople: A crumpled-up one.
* PunnyName: Being made of paper, she is very "tear-y".
* SkintoneSclerae: Like Alan, she has a drawn-on face with no coloring, though in this case that just happens to make her sclerae white.
* TerrifiedOfGerms: She's constantly spraying things clean while talking about how many germs are covering everything. This is apparently a result of her looking at a lot of pictures of infections her doctor mother posted on her medical website.

!!Tina Rex
-->Voiced by Dan Russell (Season 1), Stefan Ashton Frank (Season 2 onward)

A 3D [[FunnyAnimal Tyrannosaurus rex]] bully, though despite her fearsome appearance, she's only a bully because everyone expects her to be like her father (who is worse than her).


* ArtEvolution: In Season 1, she originally had a cartoon-like design similar to the old T-Rex depictions. In Season 2, she is given a more realistic design similar to modern T-Rex depictions.
* BarbaricBully: She's a ''pre-historic'' bully.
* TheBully: A very intimidating one.
* DemotedToExtra: Tina is one of the only classmates of Gumball's to have become ''less'' prominent as the show has progressed: In the first season, she was one of the more frequently recurring characters in Elmore Junior High and had two episodes centered around her ("The Quest" and "The Fight"). In the second season, she still appeared normally, but the one episode planned to be about her was scrapped. In the third season, she is seen and talks fairly rarely.
* TheDreaded: Not just the students, but the school's ''counselor'' are terrified of her.
* FemaleMonsterSurprise: The other character have all known her long enough to know Tina is a girl, but her male voice and monstrous, gender-neutral appearance definitely lead most viewers to think she's male until stated otherwise.
* FluffyTheTerrible: Her name is Tina, but with her last name it becomes NamesToRunAwayFromReallyFast.
* GonkyFemme: Tina doesn't normally act very feminine, but she did try to be in the cheerleading squad and was upset when Darwin told her trying to act girly doesn't work for a huge tyrannosaurus.
-->'''Darwin:''' And how about you clip those stupid nails?! They're not gonna make you look more feminine. In case you haven't noticed, you're a ten ton sack of reptile flesh!
* EverythingsBetterWithDinosaurs: Not the case, especially not when her dad gets involved...
* HiddenDepths: Tina apparently dreams of being a pianist.
* IAmNotMyFather:
-->'''Tina:''' Everyone thinks I'm a brute, just like my dad. ''But I'm not!''\\
''([[IResembleThatRemark Tina kicks a scrap car away]])''
* JerkassFacade: It is revealed in "The Fight" that she wasn't intentionally bullying Gumball, she just acts that way because of her scary father and the fact that it is what people expect when they see a T-rex that [[DoesNotKnowHisOwnStrength Does Not Know Her Own Strength.]]
* JerkWithAHeartOfGold: She shows shades of this from time to time.
* LarynxDissonance: Has a very deep male voice (and is voiced by a man), due to being a Tyrannosaurus.
* MeaningfulName[=/=]PunnyName: T.(na) Rex the T. Rex
* TyrannosaurusRex: The only T. rex in her school.

!!Tobias Wilson
-->Voiced by Rupert Degas (season 1) & Hugo Harold-Harrison (season 2 onward)

A [[CartoonCreature many-colored stylized cloud]] with a very overinflated self-image.

* AccessoryWearingCartoonAnimal: Only wears shoes and sweatbands around his wrist and forehead.
* CasanovaWannabe: Showed hints of this in the second season, especially when he tried to make a video about talking to girls in "The Tape". By the third season, he's hitting on and being rejected by every girl in school. He's basically the only person in the whole show [[NiceGirl Penny]] is ''not'' nice to.
* {{Cephalothorax}}
* CharacterizationMarchesOn: Applies not so much to him as to how everyone else treats him: during his first appearance in "The Third", it's pretty obvious to the audience that he's not as great as he claims, yet [[FakeUltimateHero everyone thinks he's genuinely cool and interesting.]] In seasons two and three, he usually portrayed as one of the least popular people in the whole school, despite being a jock.
* DumbJock: Tobias isn't very smart.
* JerkJock: He definitely ''thinks'' he's a jock, and can be pretty well a jerk.
* HopelessSuitor: He constantly goes after Penny in "The Knight", despite her openly rejecting him at every opportunity. His attempts are so hopeless that [[CrazyJealousGuy Gumball]], the guy who was furious over a ''dream'' of Darwin kissing Penny, doesn't see Tobias as any kind of romantic competition.
* NotAZombie: Inverted in "The Joy", as being ignored by all the girls left him the only one not infected with the happiness virus that gives you rainbow drool, but his technicolor appearance made Miss Simian think he was anyway (possibly that's why none of the male infected bothered him either).
* SmallNameBigEgo: He thinks he's super athletic and popular, but he's incredibly scrawny, all the girls hate him, and he's generally thought of as a loser. In "The Voice" he [[LeaningOnTheFourthWall can't understand why]] everything important happens to [[WeirdnessMagnet Gumball]], and thinks [[WrongGenreSavvy if anyone should be the main character it should be him.]]
* {{Tuckerization}}: His name [[ comes from]] Tobi Wilson, one of the show's writers.


A winged eyeball that never talks.

* BewareTheQuietOnes: [[spoiler:He's incredibly powerful and dangerous ''because'' he can't talk, but doesn't know it.]]
* FacelessEye
* {{Flight}}
* IJustWantToHaveFriends: [[spoiler:He was the one after Darwin and Gumball in "The Voice" because he ask them to be friends, they didn't understand him, and seemed to reject him.]]
* TheInformant[=/=]TeachersPet: Described as such for Ms. Simian on the website, but he never does in the actual show (and it seems he ''can't'' because he can't talk).
* MindOverMatter: [[spoiler:He has telekinesis that's strong enough to crush lockers and smash down walls.]]
* {{Oculothorax}}: An eyeball with wings, though he can still blink with fleshy eyelids [[SuddenAnatomy that sudden appear when he needs them]].
* TheSpeechless: He can't speak because he has NoMouth, [[spoiler:but until the end of "The Voice" he didn't know that and assumed everyone was just ignoring him.]]
* WhatTheHellIsThatAccent: [[spoiler:His internal monologue is provided by the show's director, who is clearly trying to mask his British accent but doesn't quite sound American either, or trying to do an impression of AlanRickman and not quite getting it. Whatever it is, it arguably makes him sound creepier.]]

[[folder:Elmore Junior High Staff]]

!!Principal Nigel Brown
-->Voiced by Lewis [=MacLeod=] (Season 1), Stefan Ashton Frank (Season 2 onward)

The school's principal [[CartoonCreature who can be best described as a furry slug.]] He and Miss Simian have a strong attraction to each other and barely bother to hide it.

* AccessoryWearingCartoonAnimal: Only wears glasses, though his fur is sometimes [[FurIsClothing treated as if it were an object of clothing]]. He may also be wearing high heels under his fur, which produce his loud clopping footsteps.
* BerserkButton: Apparently he does not take cheating on a math test well and will give whoever he catches cheating a spring break's worth of detention.
* CartoonCreature: Even ''Principal Brown himself'' doesn't know what species he is.
-->''"I tried to hibernate until spring, but it turns out that whatever I am doesn't do that."''
* DeanBitterman: Principal Brown can be rather petty, once giving Gumball detention specifically because it might have messed up his face, although sometimes he's the ReasonableAuthorityFigure reacting to something ridiculous Gumball or Darwin did.
* EyeGlasses: His eyebrows are clearly on top of his glasses. He once [[TheGlassesComeOff took off his glasses]] dramatic, showing he had ''another'' pair of glasses under that while the glasses he took off still had irises and eyebrows on them.
* HumiliationConga: He's quite prone to these:
** In "The Mystery" he was slammed with a door [[spoiler:by Mrs. Simian]], leaving him dizzy and causing him to fall down the stairs, covering himself in toilet paper, then smashed into Penny's painting and falling into some burning chemicals, causing him to fall down MORE stairs and wrapping himself in more toilet paper, then finally landing inside Gumball's locker.
** In "The Meddler', Gumball crashes into him and he spills his hot coffee all over his face. He douses the coffee with a can of paint, burning his eyes; he washes off the paint with chlorine for the pool, burning off all his hair; and he finishes by neutralizing the chlorine with fertilizer, painfully growing his hair back. He is unscathed by the end of it, but he gives Gumball detention for potentially damaging his face.
** Happens in "The Sock", though at a smaller scale. In this episode he has his head set on fire, and later he throws himself out of a window to "rescue" Miss Simian.
** In "The Apology" Miss Simian repeatedly trashes his office in rage every time she fails to get Gumball and Darwin in trouble. So he glues everything down. [[FailureIsTheOnlyOption And it all gets stuck to him.]]
* MoralityPet: He is probably the ''sole'' being that Miss Simian shows a soft side to.
* OfficialCouple: With Miss Simian.
* PhonyDegree: "The Fraud" shows his degree in teaching is fake. He's worried about being exposed, but everyone who knows agrees to keep is secret so long as he actually focuses on his job.
* ReasonableAuthorityFigure: Usually he's not (in "The Burden," he stops caring about being a principal at exactly 4:00 in the afternoon, especially if it's a weekend and he has plans with Miss Simian), but in "The Apology" he refuses to punish Gumball or Darwin unless he's given solid evidence and he threatens to fire Miss Simian if she keeps trying to frame them, in spite of his personal feelings for her. WordOfGod and the episode "The Sock" reveal that his relationship with Miss Simian is cutting into his professionalism.
* RedOniBlueOni: Blue Oni to Miss Simian's Red Oni.
* TotallyRadical: In "The Fraud", where he tries to keep Gumball and Darwin silent from discovering that he had a fake diploma, one attempt was dressing up in a hip-hop outfit and speaking in 2010s terms such as piercings, hashtag, YOLO, selfies and swag. This went on until Mr. Small had to hit him with a cafeteria tray for being a Jerkass and attempting to be cool.

-->'''Voiced by:''' Dan Russell

A [[CartoonCreature red, cube-like person]] who takes over Miss Simian's/Mr. Small's duty as P.E. teacher in the third season.

* BaitAndSwitchTyrant: When introduced in "The Coach", she seems like a blowhard DrillSergeantNasty, not letting Darwin and Gumball use their excuse note for gym, exhausting everyone in class, talking about ridiculous stories of her accomplishments, and seeming to [[TeachersPet overly favor Jamie]]. Halfway into the episode, she keeps Jamie from beating up Gumball and makes her apologizes, to everyone's completely shock. From that point, it becomes clearly she's just a regular gym coach, even if she's overbearing and somewhat dense.
* {{Cephalothorax}}
* TheCobblersChildrenHaveNoShoes[=/=]{{Hypocrite}}: She's in charge of physical fitness and goes on about how necessary it is, but she's in such terrible shape (literally and figuratively) that she gets exhausted running even the shortest distance. [[spoiler:On the other hand, her daughter is very physically fit.]] Ironically, she's much better at her job than most of the staff, as her introduction has most of the students getting the first real workout they've had in their lives.
* TheComicallySerious: She always speaks in a declarative monotone even when describing completely ridiculous situations where gym class lessons would come in handy.
* FullyDressedCartoonAnimal: Something she has in common with [[spoiler:her daughter.]]
* LadyLooksLikeADude: Despite the voice and gender-neutral-to-masculine appearance, Coach is actually a woman, something Gumball and Darwin didn't realize until the end of her introductory episode. [[spoiler:Specifically, she's Jamie's mom.]]
* LarynxDissonance: Like Tina, she is female but voiced by a man--the ''same'' man who [[TheOtherDarrin previously]] voiced Tina, in fact.
* MasculineGirlFeminineBoy[=/=]TinyGuyHugeGirl: She's a giant red cube with a man's voice; her husband is a tiny green man with an effeminate voice. Given [[spoiler:her daughter looks somewhat like her father but nothing like her]], this is probably also an InterspeciesRomance.
* TheMunchausen: She claims to have won at least three gold medals. The only proof she has are pictures (or just one picture) where she looks exactly the same as she does now and takes up the entire picture, and some of the details are blatant nonsense[[labelnote:like]]She mentions winning in 1986 and 1996 for unspecified gymnastic events and in 1988 for Taekwondo. Gymnastic events are held at the Summer Olympics, which ''weren't held'' in 1986, and if they were, they wouldn't be held in 1988 or 1996. Olympic gymnast also tend toward a rather narrow age range (about 16-18), so one attending two games over ten years apart is astoundingly unlikely.[[/labelnote]].
* RapunzelHair: She's a [[ZigZaggingTrope very odd]] example. Her hair goes all the way down to her butt, but she's a {{Cephalothorax}}. This creates a strange paradox where he hair can look short or very long depending on if you're comparing it to her face or her body.
* RunningGag: Trying (and failing) to whistle.
* SarcasmBlind: She demonstrates this when trying to explain the use for skills learned in P.E.
-->'''Coach:''' Let me paint you a picture. You're being chased by another pack of angry dogs. You've reached a ravine [[BenevolentArchitecture with only asymmetric bars allowing you to reach the other side]]. They want your pen. What do you do? \\
'''Gumball:''' I guess I'd just turn on my jet pack, fly over the ravine, land in my flying car, and drive ''to space.''\\
'''Coach:''' [[HypocriticalHumor That's completely unrealistic.]]
* SportsHeroBackstory: Coach claims to have won gold medals at several different Olympic events, but it's pretty obvious that's she's making it all up.

!!The Nurse

The school's put-upon nurse, [[AnimateInanimateObject a living adhesive bandage]].

* AstonishinglyAppropriateAppearance: She's a nurse and a living band-aid--as are most of the other medical personnel in the show, including doctors and paramedics (barring Dr. Butt as seen in "The Goons" and the pig doctor from "The Saint").
* DrJerk: Having to put up with Gumball and Darwin looking for doctor's notes, Teri's {{hypochondria}} and other general craziness has left her a tad cantankerous.
* FullyDressedCartoonAnimal: Assuming the dress and shoes aren't just part of her body.
* ImADoctorNotAPlaceholder: When people keep sending Bobert her way for fixing, she reminds them she isn't a mechanic. Miss Simian points out that Elmore has all kinds of weird students, so she should just shut up and deal with it.
* NerdGlasses: She wears enormously oversized eye glasses--or rather lenses inexplicably attached to her face.
* NoNameGiven: Like the Sheriff, no one has ever called her by name.
* SphereEyes

!!Miss Lucy Simian
-->Voiced by Sandra Searles Dickinson (season 1) & Hugo Harold-Harrison (season 2 onward)

An [[TimeAbyss impossibly ancient]] [[FunnyAnimal monkey]] who teaches at Elmore Junior High. Her and Principal Brown have a strong attraction to each other and barely bother to hide it.

* ZeroPercentApprovalRating: Loathed by the entire town, Principal Brown excluded. Even Rocky, a NiceGuy who claims to like everybody, openly admits he hates her.
* ActionSurvivor: Of the joy virus in "The Joy". [[spoiler:She also ends up being the FinalGirl.]]
* ApatheticTeacher: Really doesn't care about the children's education (though you wouldn't either if you've been teaching since the Stone Age) -- she said as much on "The Butterfly" and it's all but stated that she only has this job because she's dating Principal Brown.
* ArtEvolution[=/=]EarlyInstallmentWeirdness: In Season 1, she was originally [[ a rigid blocky character]] with a rather prominent shade of gray, and had a polka-dotted dress. In Season 2, she is given more color, a completely pink dress, a more rounded body, better computer animation, and some slightly noticeable FanDisservice JigglePhysics in her much more saggier boobs. Also, in season one, Miss Simian was voiced by a woman (Sandra Searles-Dickinson) and had a slight British-American accent. From season two on, [[CrossDressingVoices Miss Simian is voiced by a man]] (Hugo Harold-Harrison) and just has an American accent.
* BaldOfEvil[=/=]GirlsWithMoustaches: She's technically bald with a beard. Given she's a monkey, this wouldn't be especially notable if it weren't for it being pointed out to her in "The Boombox" by Principal Brown, showing she had not noticed before.
* BarefootCartoonAnimal: Wears a full dress but no shoes. Given her feet are realistically primate-like, she probably couldn't fit them in a regular pair of shoes.
* EverythingsBetterWithMonkeys: Judging by her face and red bottom, she's some sort of mandrill or baboon. Despite clearly having a tail (not pictured here, but visible on the show), she's still often called an ape.
* ElderlyImmortal: It's unknown if she's lived 300,000 years because of actual immortality (which is debatable, since her father is older than her, yet is currently a skeleton on display at a natural history museum while she's still alive), but regardless, she looks quite old.
* FanDisservice: What her body shows (on both the season one and season two designs, with the season two design being more obvious).
* ItsAllAboutMe: Her mug even says, "I Love Myself"
* JerkWithAHeartOfJerk: In "The Ape", she was a complete JerkAss to Nicole when she was young and would even use Gumball and Darwin just to get the Teacher Award. She was given a choice to either get the form with the signature on the car and fall out of the bridge or get off the car and redeem herself by staying friends with the Wattersons. [[IgnoredEpiphany She went "Nah!" to the latter and does the former, which leads to her fall]].
* MeaningfulName: [[ Lucy]] is also the nickname of an important hominid fossil.
* NominalHero: In "The Joy", while she's doing it for purely selfish reasons (recognition, not liking the sight of so much happiness, etc.), she still tries to stop the spread of the titular G-Rated ZombieApocalypse (even though she failed).
* NotSoAboveItAll: She's a {{Jerkass}} to end all Jerkasses...but she loves a good party.
* OfficialCouple: With Principal Brown.
* PetTheDog: She showed herself to not be ''completely'' heartless in "The Apology," as she gave up her attempts to frame or catch Gumball and Darwin when they attempted to actually get in trouble to save her dignity, her job and her relationship, and even attempted to clean up the mess they made to keep them out of trouble. Even when Darwin completely milks the fact that she's actually saying sorry for her behavior, she just chuckles. It's a surprisingly sweet moment for such a mean character.
* RedOniBlueOni: Red Oni to Principal Brown's Blue Oni.
* SadistTeacher: {{Zig Zagg|ingTrope}}ed; she's almost always portrayed as grumpy, self-centered, and mean-spirited when Principal Brown isn't present, but if this translates to actively picking on her students or Gumball specifically varies by the episode.
* SpeciesSurname: Although a bit wider than "species", as "simian" is an infraorder (a taxonomy level between an order and a family).
* TimeAbyss: At least 300,000 years old. She's so old, she taught during the Stone Age, was around to mock Nicole at every turning point in her life[[note]]her first steps, her first bike ride, the first time she failed a school assignment, her first dance, and her wedding day[[/note]] and her father's skeleton is currently on display at a natural history museum.

!!Rocky Robinson
-->Voiced by Lewis [=MacLeod=] (Season 1)

Mr. and Mrs. Robinson's estranged son and a [[CartoonCreature muppet creature]] like his parents (even though he's orange and they're blue). He works numerous non-teaching positions at Elmore Junior High (mostly the janitor, the cafeteria worker, and the bus driver).

* AlliterativeName: '''Ro'''cky '''Ro'''binson.
* BarefootCartoonAnimal: Unlike his parents, he wears no shoes.
* BlackSheep: His father disowned him because he won't take a respectable job, never left school, and [[ArsonMurderAndJaywalking dresses like a Canadian]].
* BlandNameProduct : He wears an [[Music/AcDc AB/CD]] shirt in season one. From season two to now, the logo was changed to "Bisou" and stylized after the logo for the band "KISS".
* {{Catchphrase}}: "Word."
* LikeFatherUnlikeSon[=/=]WhiteSheep: His parents are both very mean, grumpy, and serious, but Rocky himself is friendly, happy, and laid-back.
* NewJobAsThePlotDemands: He fills pretty much every non-teaching, non-administrative job at school, usually the janitor, the cafeteria worker, and the bus driver.
* NiceGuy: In "The Ape" he tells Mrs. Simian that not even ''he'' likes her... and he likes everybody!
* ReplacementGoldfish: Becomes a literal replacement goldfish for Darwin in "The Genius", who Nicole and Richard insist on calling "Rockwin".

!!Steve Small
-->Voiced by Rupert Degas (season 1) & Adam Long (season 2 onward)

The [[CartoonCreature humanoid covered in fluffy hair]] who acts as Elmore Junior High's guidance counselor.

* AlliterativeName: The first letters of his first and last name begin with a "S".
* AmericanAccents: He had a slight Dixie (Southern U.S.) accent in the first season. Season two on, he had a stereotypical hippie voice.
* CharacterizationMarchesOn: In season one, Mr. Small's hippie-like tendencies weren't so pronounced and it was generally implied that he was much meaner and shiftless than he let on, whereas after that he seems to genuinely be a complete doormat. And, as mentioned in the AmericanAccents entry above, his first voice actors played him with a Southern accent.
* ChewToy: Him being injured as the result of the protagonist's actions has become a RunningGag since the end of season one.
* {{Cloudcuckoolander}}: Even besides his deliberately "hippie" behavior, he's done strange things like writing an ''extremely'' long poem from the point of view of a shoe and thinking he's become one with the universe when he woke up in a room full of foam.
* DrillSergeantNasty: He's the judge for cheerleading tryout and is [[SchoolClubsAreSeriousBusiness extremely serious about it]] for a team [[ClubStub with about six members]].
* FullyDressedCartoonAnimal
* [[HippieTeacher Hippie Counselor]]: Though he's rather less patient than the typical example.
* MoodSwinger: Can go from an easy-going hippie to an enraged maniac in a snap.
* NewAgeRetroHippie: Right down to the rainbow shirt, temporarily having a diet that was just sunlight, talking about "the man," having a hippie van named Janis (possibly named after JanisJoplin), and even being a ''literal cloud''. There's even [[GettingCrapPastTheRadar a few moments implying he is indeed a stoner]]; drinking herbal tea that makes him black out and on "The Void," he can bounce through the dimension of the world's mistakes because he's, "...used to feeling spaced out."
* NothingButSkinAndBones: On a few occasions where he wears skin-tight clothes (or any type of revealing clothes, like the midriff-bearing holistic doctor outfit he wore in "The Allergy," the tattered clothes he had in "The Pizza," and when he wore nothing but a loincloth in "The Void") we can see his ribcage with a disturbing amount of detail. Justified as he starved himself on a diet of sunlight and (rarely) eats meat.
* LargeHam:
-->"Don't hate me because I'm ''beautiful!''"
* PissTakeRap: Has one about honesty; while dressed in a ''bear costume''.
* PsychoPsychologist: Mr. Small is the school's counselor but really needs therapy more than any of his students. Especially in the first season, where he often showed himself to be violently bipolar.
* ScareEmStraight: Does this to Gumball and Darwin by showing them a grotesque diagram of the soul of a liar. This can also be applied to his sock puppet, the Silence Snake, whom he uses to scream at people and shock them into shutting up.
* SphereEyes
* StrawVegetarian: In "The Castle" he states he's only a vegetarian so he can rub his superiority over not eating meat in everyone's faces. In "The Pizza," it's revealed that in dire survival situations, he will turn to cannibalism, but only if the person about to be eaten hasn't had any antibiotics or anything that's not considered organic. Principal Brown in "The Fraud" mentions that he hates vegetarians because they're boring, always go shirtless, and have a smug superiority to them, which may or may not be how he really feels about Mr. Small.
* {{Tuckerization}}: Named after a friend of the show's creator that also works in animation--the same one that made his character design, in fact.
* UnmovingPlaid: His rainbow-patterned shirt [[ played this straight]] a few times in season one. Every other time it's a {{downplayed|trope}} example, because the pattern will rotate and shift as his body parts move, but [[ does not change when his shirt gets folded]].


[[folder:Other Citizens of Elmore]]

!!Banana Bob and Banana Barbara
-->Voiced by Hugo Harold-Harrison (Bob)

Banana Joe's parents, two other [[AnthropomorphicFood bananas.]]

* AccessoryWearingCartoonAnimal: Barbara wears a polka-dot ribbon. Bizarrely, Bob's mustache was shown in "The Shell" to actually be a detachable accessory.
* TheChewToy: Barbara is subject to a large amount of prat-falls in "The Mothers", many of them caused by [[TheKlutz her extreme clumsiness.]]
* HiddenDepths: Banana Bob used to be a musician. And a bank robber.
* LookalikeLovers: They're basically identical save their TertiarySexualCharacteristics, as seen in "The Shell" where it's revealed that Banana Bob's mustache is detachable and, without it, his voice is very high and girl-like.
* MadOracle: In "The Shell" it's implied that Banana Barbara paints portraits that predict the future. "The Oracle" shows that she's been doing it for years, though Banana Joe never noticed because all of them were of the Watterson family. And any time she's seen making one, she [[ThousandYardStare stares around blankly]].
* ObliviouslyEvil: Banana Bob mentions in "The Oracle" that people threw their hands up and gave him money any time he put on a [[BlatantBurglar balaclava]] (or "bananaclava" as he calls it) and walked into a bank, not understanding that those people thought he was robbing them.
* SpeciesSurname: Like their son, "Banana" is their family name even though it's their first.
* TertiarySexualCharacteristics: Barbara has eyelashes, lipstick, and a bow while Bob has a mustache. In "The Shell," Banana Bob's mustache is detachable and the only thing keeping his voice masculine, which carries some odd implications.

!!Billy and Felicity Parham
-->Voiced by Sandra Searles Dickinson (Felicity)

A mother and child who are both [[CartoonCreature abstract blobs]] colored orange and blue, respectively.

* AbusiveParents[=/=]HilariouslyAbusiveChildhood: Billy does not have a very good mom.
** In "The Extras," she crashed her car (with her son in it) into a house and left him in there while she walked out and beaned herself on the head with a shovel.
** In "The Gripes," she threw her son in the trunk of the car and buckled up her groceries [[HypocriticalHumor as she accused Gumball's father of being a bad parent]].
** In "The Law," she leaves her son behind when she hijacks the ice cream truck and goes on a crime spree.
** In "The Butterfly," she shoved her own son out of the way when he was chasing after the $20 bill that the hairy hobo lost. [[LaserGuidedKarma Fortunately, she got what was coming to her when Mrs. Robinson shoved her out of the way to get the $20 bill]].
* AscendedExtra: They started as {{Recurring Extra}}s throughout season 2[[labelnote:before that]]A completely different-looking boy, who once spoke with the same voice as Billy, and his mother were seen several times in the first season[[/labelnote]], then they got a skit in "The Extras" and major roles in "The Law" and "The Egg".
* AxCrazy: Felicity, and ''how''.
* BlueOrangeContrast: Not only are they blue and orange, but the mother has blue lips.
* RichBitch: It's not clear exactly how rich they are, but they're both pretty stuck up. When it appears to them that Gumball and Darwin were being arrested, the mother assumes it's because they went to public school.
* SphereEyes
* StepfordSmiler: Beneath her cheery demeanor, Felicity is quite unhinged. In their skit in "The Extras" when she got tired of Billy's pestering, she crashed her car into their house and knocked herself out with a shovel so she didn't have to listen to him. In "The Law," the sight of Gumball not being stopped by the Doughnut Sheriff (who was fired) for ''jaywalking'' enrages her so much that she immediately figures law and order doesn't exist anymore, hijacks Larry's ice cream truck, leaving her son behind, and plows through Elmore until she reaches the police department and threatens to kill the Chief of Police with an ice cream cone.
* {{Tuckerization}}: Their last name comes from one of the show's writers, Joe Parham.
* UnexplainedAccent: Billy has a British accent[[note]]specifically ReceivedPronunciation, so it's probably not even one of the show's British voice actors NotEvenBotheringWithTheAccent[[/note]], even though his mother and the rest of Elmore do not.
* UnnamedParent: Until "The Egg", Felicity's name was never stated.

!!Patrick Fitzgerald
-->'''Voiced by:''' Dan Russell

Penny's father, another [[AnimateInanimateObject living peanut]] [[MixAndMatchCritters with antlers]]. [[spoiler:Although beneath his shell he's presumably a spectral shapeshifter with antlers like his daughter.]]

* AccessoryWearingCartoonAnimal: Normally wears only sandals with socks under them. When at work he also wears a hardhat and when jogging he replaces the sandals with tennis shoes and adds sweatbands.
* BlackBeadEyes: Like his daughter, his eyes look like this, but actually seem to be holes in his shell.
* EarlyBirdCameo: Gumball, Darwin, and Nicole run through his backyard in "The DVD", when he wouldn't get a speaking role until "The Date" later that season.
* FatIdiot: Subverted. Mr. Fitzgerald is scarily on the ball when it comes to parenting, and seems to be a very authoritative and strict person, despite his size - which, given what the Fitzgeralds are like under their shells, may not be indicative of his weight anyway.
* LargeAndInCharge: The biggest in the Fitzgerald household.
* OnlySaneMan: Has a justified grudge against the Wattersons, [[PapaWolf and Gumball in particular]], but is unusually quick to put it aside as events dictate. Was pretty much the only Elmore resident who was willing to work ''with'' the Wattersons in some way during the events of "The Finale" (by taking a fall in a "Dad Fight" between him and Richard, as things had clearly gotten well out of hand with the crowd and all).
* OverprotectiveDad: He refuses to let Penny see Gumball after his family makes a bad impression in "The Knights", and flat-out refuses to even let her say anything about it. "The Shell" implies a lot of this is because their whole family are secretive about what they're like under their shells, but this ends up backfiring and making Penny feel ashamed after she leaves her shell. Since "The Shell," however, Patrick hasn't been as overprotective or as antagonistic to Gumball: In "The Spoiler," he still feels the need to eavesdrop over Gumball and Penny's phone conversation, but he's notably less hostile towards Gumball than he was before and actually feels bad about revealing a major plot point in ''The Screamening''.
* PapaWolf: To Penny. The fact that she likes [[IdiotHero Gumball]] doesn't help. However, as of "The Shell" (when Gumball called him out on hurting Penny's feelings when she was freaking out over her new form, then consoled him and told him that "parenting is hard" and went through hell to get Penny back to her default form and back to her father), Patrick has loosened up a bit.
* UglyGuyHotWife: His wife isn't fat like he is, though he seems to be in much better shape than Richard.
* UnnamedParent: His given name (Patrick) wasn't stated until "The Shell". The same episode played with it by Gumball repeatedly calling him some variation of "Robert", when the audience would have no idea that he was wrong.

!!The Chimera

A large, strange creature made of many different parts (mostly Lego bricks, a Barbie doll leg, a plastic shark's head, and a leg from an action figure of The Thing from The Fantastic Four). He pretended to be an imaginary friend created by Anais, Darwin, and Gumball but was actually a creation of a lonely toymaker who outlived him.

* {{Adorkable}}: His social skills are rather poor because he'd previously never talked with anyone but his creator. Gumball even tells Anais that [[LonelyTogether she finally found someone as socially awkward as her]], [[HellYesMoment to her delight]].
* BizarreTasteInFood: He eats hair.
* DetachmentCombat[=/=]PullingThemselvesTogether: Although he doesn't use them to fight, The Friend can remotely control his detachable pieces and reassemble himself at will. He shows this off by [[LosingYourHead taking his head off]] then comes together again after being blown to pieces.
* DoesNotKnowHisOwnStrength: He barely nudges a pinata and it's sent flying into the sky.
* {{Living Toy|}}: An old toymaker made him because he was lonely.
* MisunderstoodLonerWithAHeartOfGold: After his creator died, he started wandering around at random and his appearance made people scared of him even though he's actually quite nice.
* MixAndMatchCritters: And a [[OurMonstersAreWeird rather bizarre one]] even by Elmore standards: his body is a collection of LEGO-like blocks, his left arm is robot-like and has a buzzsaw, the right arm is like a giant action figure's arm, his right leg is like a mannequin's, his left like [[Comicbook/FantasticFour Ben Grimm's]], and he has a shark's head with long hair.
* NotSoImaginaryFriend: He shows up right after Anais, Darwin, and Gumball try to make up an imaginary friend together, and pretends to be the friend they made up.
* NoNameGiven: He never uses any name, isn't ask for one, and might not have one.
* OddFriendship: He forms one with Anais.

!!Granny Jojo
-->Voiced by Sandra Searles Dickinson

Richard's mother, another [[AmazingTechnicolorPopulation pink]] [[FunnyAnimal rabbit.]]

* CharacterizationMarchesOn: Rather than being overly protective, in the first season she seemed extremely ''apathetic'', not wanting to do anything in "The Kiss" but watch TV all day and uncaringly telling Richard that magic wasn't real in a flashback in "The Wand". Compare with episodes like "The Authority" and "The Man," where it's established that she was an overprotective parent to Richard and lied to him about why his father wasn't around.
* DecemberDecemberRomance: With Louie (the MickeyMouse {{Expy}}); [[ParentWithNewParamour when Richard finds out]], he freaks.
* GrossUpCloseUp: We constantly get this of her putting on her lipstick in "The Kiss".
* FreudianExcuse: "The Man" implies that [[spoiler:Richard's father leaving him and his mother 42 years ago when he was very young]] is part of why she's so overprotective.
* FullyDressedCartoonAnimal: Like her granddaughter, but unlike her son, she wears shoes.
* MiniatureSeniorCitizen: In the first season she was noticeably shorter than Richard or Nicole. [[ArtEvolution Her second season design]] is barely taller than Anais.
-->'''Granny Jojo:''' (inside, talking about the kids outside) See, this is exactly the kind of thing I was worried about. \\
'''Nicole:''' How would you know? You're not even tall enough to look out the window!
* MyBelovedSmother: She thinks a mother has to protect her family from everything [[ScareEmStraight by making them scared of everything.]] Richard's such a FatIdiot because she had him sit around eating all day, never learning how to do anything himself.
* TheNicknamer: Calls Gumball "the blue one" Darwin "walking fish" and "fish kid".
* ObnoxiousInLaws: Both Nicole and Richard prefer to be as far away as possible whenever she visits. She has an extremely low opinion of Nicole as a mother that she vocalizes regularly, yet also leans on her for ridiculous demands, making her waste one of her only four days off to be her chauffeur.
* VagueAge: In "The Man" she states herself to be 63 years old, yet she already looked old when Richard was a kid, and he's now thought to be between 40 and 50 years of age.
* ScrewPolitenessImASenior: She's very blunt, [[HeyYou doesn't bother to remember her grandkids names]], and she made Anais carry a suitcase that's clearly too heavy for her.

!!Mrs. Jötunheim
-->Voiced by Sandra Searles Dickinson

Hector's mother, a grumpy witch who has to keep her son calm, not because she's overprotective, but to keep her son from destroying Elmore.

* AbsurdlyYouthfulMother: {{Inverted|Trope}}; she looks far too old to have a middle school-aged son. Possibly whatever species she is [[YoungerThanTheyLook looks like that regardless of age]], or giants like Hector grow more slowly than "regular" people.
* BlueCollarWarlock: She is a rather comically mixture of a traditional witch (she lives in a cave, uses a cauldron, knows about magic spells, and flies on a broom) and an everyday person (she goes into town like everyone else, she works as a custodian, and she has a son in middle school).
* {{Expy}}: Her character design is heavily based on [[Film/SpiritedAway Yubaba]].
* InterspeciesRomance: Her husband is stated to be a giant even bigger than Hector, implying she's a member of some WitchSpecies, rather than a giant that shrank with old age. [[HotSkittyOnWailordAction And she's not even as big as a human.]]
* GoodIsNotNice: Mrs. Jötunheim is fairly unpleasant to talk to, but is the main thing keeping Hector from destroying the town and helps Gumball from the Snatcher in "The Mirror" without asking for anything in return.
* MiniatureSeniorCitizen: Even Gumball towers over her.
* MyBelovedSmother: She's extremely controlling of everything Hector sees and does, even vetoing his online friend invitations and heavily censoring his comics. [[PlayingWithATrope However,]] this isn't to protect Hector, it's to keep him calm, protecting everyone else ''from'' him.
* WickedWitch: She turns out to really be a witch, as Gumball had guessed, and has a lot of the visual traits, including discolored warty skin, [[SinisterSchnoz a big nose]], and a {{witch broom}}, [[SubvertedTrope but isn't really evil.]]

!!Laurence "Larry" Needlemeyer
-->Voiced by Kerry Shale

A skinny man [[RockMonster made of rock]] who works many different jobs throughout Elmore.

* BarrierMaiden: He holds so many jobs that his continued employment is required to keep Elmore's economy (and society as a whole) from spontaneously collapsing.
* CartoonCreature: [[!/benbocquelet/status/171333727501295616 He's suppose to be]] a [[RockMonster rock-man]], but his design makes this slightly hard to tell.
* ChewToy: He can hardly make an appearance where something terrible doesn't happen to him -- usually at the hands of the Watterson family.
* FullyDressedCartoonAnimal: Wears a shirt plus LongPants.
* FunnySchizophrenia: In "The Game", he takes a pizza being ordered to his own address from a PrankCall, then argues with ''himself'' over who pays for it, ultimately throwing the pizza in his own face.
-->'''Larry:''' I think all these jobs are messing with my head.
* HumiliationConga: Goes through one at the hands of Gumball and Darwin in "The Laziest", as they get him fired while causing his car to be destroyed and girlfriend to dump him. [[UnexplainedRecovery He's back to normal by his next appearance.]]
* NewJobAsThePlotDemands: Runs pretty much every shop in town and does a lot of other jobs as well that isn't already covered by other characters. {{Lampshade|Hanging}}d in the "The Finale" where it is explained that because of the Wattersons' constant antics, he has to take on more than one job in order to pay for all the damage they caused for him. In "The Pizza", it turns out he's the ''only'' one in town doing many of these things (including pest control worker[[note]]even though "The Shell" showed that a cockroach, ironically, is the town's pest control worker...unless he got fired for shooting Nicole with a tranquilizer dart while trying to subdue Penny during her shapeshifting freak-out and Larry took over[[/note]], police station accountant, and roadside repairman), and if he goes, the town's economy falls.
* ThatManIsDead: He used to be "Lazy Larry", the laziest person in Elmore, but after he lost that title to Richard he's been trying to get his life together and doesn't like being called "Lazy Larry" anymore.

!!Richwood High Tennis Team
-->Voiced by Stefan Ashton Frank (Mr. Kreese)

A trio of [[StylisticSuck poorly-animated]] (looking similar to how humans are animated in most 1980s cartoons, like ''GIJoeARealAmericanHero'' or anything by {{Filmation}}) humans: two high-school tennis players named Carlton and Troy and their coach, Mr. Kreese. They're the only humans to appear on the show in person (not counting Santa Claus, who may be a sort of elf/fairy).

* AmbiguouslyBrown: Troy has a somewhat dark skin tone, but it might just be a tan.
* BunnyEarsLawyer: In spite of their delusional behavior, Carlton and Troy are actually extremely skilled at playing tennis. The one time Gumball actually tried to return one of their serves, the spin alone was enough to tear the racket out of his hand.
* DefeatMeansFriendship: Ironically it's after ''they'' win that Darwin and Gumball get their respect. They're impressed that Gumball managed to keep playing after a minor injury, despite neither one trying to win before or after it.
* TheDividual: Carlton and Troy are, for most purposes, the same person.
* {{Expy}}: Carlton/Troy and Mr. Kreese blatantly parody the arrogant but honorable student/ruthless coach dynamic of Johnny and John Kreese in ''Film/TheKarateKid''. Although unlike John Kreese, Mr. Kreese has a HeelFaceTurn.
* ImpossiblyTackyClothes: They wear extremely stereotypical [[OutdatedOutfit 1980s clothing]], including tennis shoes and high-socks with rainbow highlights, long wavy hair, rectangular shades, and brightly color sweaters worn as both clothing and accessories for the shoulder and waist at the same time.
* ManChild: Mr. Kreese engages in UnsportsmanlikeGloating with all the grace, eloquence, and enthusiasm of a five-year old.
* NonStandardCharacterDesign: Their designs look like they're from a 70s or 80s cartoon made by Creator/{{Filmation}} or Creator/{{Sunbow|Entertainment}}. Even with the show's extremely diverse art style they're all ''very'' out of place.
* OpposingSportsTeam: Relentlessly parodied: all three continuously insist that they're "more hardcore" than Darwin and Gumball, despite facing no disagreement, and [[TheThingThatWouldNotLeave won't stop bothering them]] until the two accept their challenge to prove it.
* {{Retraux}}: Their 80s-ness extends not just to their clothes and character design, but also their ''animation'': their movement are all very choppy, they make flamboyant mannerism reminiscent of ''Anime/SpeedRacer'', [[ closeups]] show them with non-uniform outlines and bleeding colors to make them look like they're cel-animated, and there are some [[StylisticSuck deliberate art errors]] like Carlton suddenly having freckles for just one scene.
* RichBastard: Carlton threatens to have his rich dad [[SavingTheOrphanage bulldoze Elmore Junior High to make a golf course]] if Gumball and Darwin don't have a tennis match with them.
* TokenHuman: They are the only human character seen in-person. However, Carlton, Troy, Mr. Kreese, and the background characters of Richwood High are animated rather than live-action like the humans shown on television, so they [[AmbiguouslyHuman might not be quite the same thing]].
* WrongGenreSavvy: All of them act like they're in a cheesy 80s sports movie when they're really in an episode of a cartoon parodying those movies. Unfortunately, their presence seems [[InfectiousInsanity to cause almost everyone else to act the same.]]

!!Gaylord Robinson
-->Voiced by Rupert Degas (Season 1) Stefan Ashton Frank (Season 2 onward)

The Watterson's cranky neighbor who appears to be [[CartoonCreature a sort of Muppet creature]] or a [[LivingToys muppet come to life]]. In spite of his attitude, Gumball and Darwin adore him.

* BigOlUnibrow
* CrankyNeighbor[=/=]GrumpyOldMan: Mr. Robinson's smug sense of superiority toward the Wattersons is one of his only sources of enjoyment, and he's constantly trying to find something wrong with them, going so far as to camp in his trash can all day to find out if they were using it without his permission. He even sometimes drives his car around town, trying to make as many people miserable as possible.
* FullyDressedCartoonAnimal
* [[HappilyMarried Unhappily Married]]: He and his wife Margaret are "happily" married because they argue, ''a lot''.
* HiddenDepths: Despite his uptight personality, he has a love of dance, and gives a big musical performance in his first episode.
* HopelessWithTech[=/=]TechnologicallyBlindElders: He doesn't know how to program his alarm clock (he says this himself ''as he sees someone else is doing it'') and mistakes a video camera for a musical instrument.
* LookalikeLovers: Broadly; he and his wife are both CGI muppets with the same nose and color scheme, but their hair and body shapes are entirely different. Strangely, their son has his father's body shape, but neither the color or nose his parents share.
* MarionetteMotion: [[InvokedTrope Invoked]], given [[Creator/JimHenson what]] [[TheMuppetShow he's based]] [[{{Muppet}} off of]].

!!Margaret Robinson
-->Voiced by Teresa Gallagher

Mr. Robinson's wife, another [[CartoonCreature muppet creature]], who speaks only in mumbles.

* CrankyNeighbor: She doesn't go out of her way to antagonize the Watterson as much, but clearly hates them as well and enjoys cutting flowers from her garden just because she can.
* FullyDressedCartoonAnimal
* [[HappilyMarried Unhappily Married]]: See Mr. Robinson's entry above.
* HartmanHips: Her body shape is basically a tiny torso on top of large, egg-shaped hips.
* LookalikeLovers
* TheUnintelligible: She speaks only in unintelligible grunts and grumbles. Her husband [[IntelligibleUnintelligible can understand her]] at least, albeit with some difficulty.
* YourCheatingHeart: In "The Boss," while Mr. Robinson was in the hospital, suffering from a stuffing deficiency, she ran off to go on an island vacation and nearly married one of the sailors she met there.

!!Sal Left Thumb
-->Voiced by Kerry Shale

A [[AnimateInanimateObject giant thumb print]] and resident career criminal. Though not seen often in the series, his face is shown on a lot of wanted posters posted on walls, fences, and in stores (with a cash reward of $25 if caught).

* AccessoryWearingCartoonAnimal: Only wears a mask.
* AmericanAccents: Has a thick Bronx-accent.
* AstonishinglyAppropriateAppearance: He's a criminal and a walking piece of forensic evidence.
* BlatantBurglar: He's always shown wearing a DominoMask, except a flashback that showed him as a kid.
* ImprobableWeaponUser: He uses a ''[[FunnySpoon spoon]]'' to rob people. He never actually uses it for anything but threatening people; it's basically a [[ExaggeratedTrope very over-the-top]] form of FamilyFriendlyFirearms.
* SphereEyes
* VerbalTic: Says 'suckers' a lot, which is what eventually gets him in trouble at the end of "The Spoon".

!!Senior Citizens
-->Voiced by Dan Russell (Marvin)

A group of old people usually seen sitting together on a lawn. They include [[FunnyAnimal a mouse]] named Louie, [[CartoonCreature a red jelly bean-looking blob]] named Marvin Finklehimer, a lady who appears to be [[AnimateInanimateObject a segment of a green chalkboard]], and a man [[CartoonCreature that looks like a collection of plaid patterns]].

* AscendedExtra: Marvin and Louie end up getting major roles in "The Watch" and "The Man", respectively.
* CoolOldGuy: Louie shows himself to be a very friendly and amiable person, despite Richard's refusal to let him date his mother. He can also dance (sort of).
* DecemberDecemberRomance: Louie is dating Granny Jojo.
* FeudingFamilies: Marvin hated the Wattersons because they'd been feuding with his family for generations over the possess of an old watch. They stop once both sides realize no one actually cares about the thing, but the feud briefly resumed once they find out it's worth a lot of money.
* RatedMForManly: Louie went against Richard in a "man off" and won every single event.
* ScatterbrainedSenior: When Louie is off his meds, he mistakes a trash can for a young man trying to compete with him in a dance contest.
* ViolentGlaswegian: The plaid man has a Scottish accent and agrees to let Gumball have his scooter if he can beat him in a fight, though [[SubvertedTrope he immediately gives up]] once he realizes he can't even get out of his chair.

-->Voiced by Kerry Shale

The [[AnthropomorphicFood donut]] police officer most often seen around Elmore.

* BadassDriver: [[ExaggeratedTrope Taken to a ridiculous extent]] at the end of "The Law", where he drove a truck off the road using a ''stroller'' instead of one of the bikes conveniently located next to it.
* CarnivoreConfusion: His [[TrademarkFavoriteFood favorite food]] is doughnuts.
* {{Cephalothorax}}
* DonutMessWithACop: He's a cop ''and'' a living doughnut, as well as the page image.
* DrivesLikeCrazy: When he was trying to show that he could be "cool", he goes on a driving spree where snaking through mailboxes was the least crazy thing he did ("Darn, missed all of them!").
* EveryoneCallsHimBarkeep[=/=]NoNameGiven: He's never addressed by name and only even addressed by rank in "The Car".
* {{Expy}}: He has a lot in common with Chief Wiggum from ''WesternAnimation/TheSimpsons'', though Doughnut Sheriff is slightly more competent than Chief Wiggum is. They're both even voiced with an Edward G. Robinson impression.
* FullyDressedCartoonAnimal: Like ''Spongebob Squarepants'', being a full dressed {{Cephalothorax}} results in him having [[DetachedSleeves sleeves for a shirt that isn't on his body.]]
* PoliceAreUseless: Zigzagged. There are times where he is competent and does his job, but for every time that happens, there are at least three or four times he does something reckless that, in the real world, would have gotten him thrown off the force years ago.

!!Video Game Store Manager

The diminutive [[CartoonCreature plush toy-like]] manager of the Ripley 2000 video store.

* AccessoryWearingCartoonAnimal[=/=]FullyDressedCartoonAnimal: Either he's wearing some kind of coveralls (with teddy bear ears) or that's part of his body and the only article of clothing is his tie.
* TheBusCameBack: He was originally just a OneShotCharacter in "The Refund", then suddenly made a reappearance in "The Question" (on the part where Larry goes mad from the realization that his life is a grind) more than two seasons later.
* HonestJohnsDealership: He absolutely refuses to give refunds for anything under any circumstances, and sold a paper shredder claiming it was a game console.
* {{Jerkass}}[=/=]MeanBoss: He makes Laurence admit it was ''his'' fault that there was traffic which caused him to be late (and probably make him say it like he means it). Then he hangs up on him.
* KillerRabbit: Subverted; despite what Needlemeyer insists, he's physically capable of nothing more than slight annoyance. The person he was attacking just happened to be a complete wuss.
* MoneyFetish: He makes ''[[WesternAnimation/SpongeBobSquarePants Mr. Krabs]]'' look generous.
* TheNapoleon: Short and incredibly aggressive.

!!Harold Wilson
-->Voiced by: Kerry Shale

Tobias's father and Jackie's HenpeckedHusband, another [[CartoonCreature many-colored stylized cloud]]

* AccessoryWearingCartoonAnimal: Wears only a tie and the front of a collar--he doesn't even wear shoes like his son does.
* {{Cephalothorax}}
* DirtyCoward: When Harold and his wife think they're in danger, he claims he can handle it, [[ScrewThisImOuttaHere but then just runs away, leaving her behind]].
* HenpeckedHusband: In "The Castle," he stays with the Wattersons because Jackie won't let him be himself at home. Taken to extremes in "The Pizza," when Harold is shown on a leash and barking when Jackie emerges from the wrecked van, symbolizing how Harold is treated like a dog[[note]]or, if you want to get vulgar, "is a bitch."[[/note]]
* NoSenseOfPersonalSpace: He likes poking people for no reason, and even went to the Watterson house in "The Castle" so his wife wouldn't stop him.

!!Jackie Wilson
-->Voiced by: Teresa Gallagher

Tobias's mother, also a [[CartoonCreature rainbow cloud person]], albeit a [[BizarreSexualDimorphism very different looking one.]]

* AmericanAccents: She has a very nasally Joisey accent, similar to [[WesternAnimation/SouthPark Sheila Brovlofski]].
* FullyDressedCartoonAnimal
* [[LikeFatherLikeSon Like Mother Like Son]]: In "The Mothers" she shows herself to be a lot like Tobias, even working with him to cheat at the Mom-off.

!!Rachel Wilson
-->Voiced by: Jessica [=McDonald=]

Tobias's older sister, another [[CartoonCreature many-colored cloud person]].

* ChuckCunninghamSyndrome: She hasn't appeared since season one (except in a picture), as Ben Bocquelet some other staff members really don't like her.
* FullyDressedCartoonAnimal: [[HumanoidFemaleAnimal Unlike her brother and dad]], she and her mom wear clothing on their bodies.



!!Anton Clones
-->Voiced by Stefan Ashton Frank (Ant-One)

Numerous clones of Anton that Darwin and Gumball made in "The Recipe" using an everyday toaster. Among them, only the first two clones were named: the burnt first one, who named himself "Ant-One", and the second, which Gumball and Darwin named "Ant-Two".

* EvilTwin: After surviving being burnt, Ant-One comes out of the garbage can to try and replace the original Anton.
* ExpendableClone: Although Darwin and Gumball worry about getting in trouble for making them, almost all of them die, and nothing seems to come of it.
* LiteralGenie: They're so naive that they'll follow whatever orders they hear first as literally as possible, even taking "split up" to mean "tear yourself in half".
* NotEnoughToBury: [[spoiler:Ant-One falls into a pool and is torn to pieces by the grate of the drain he's sucked into.]]
* SoleSurvivor: [[spoiler:Ant-Two is the only clone left at the end of "The Recipe". The "real" Anton also died, but he was just a different line of clones that would presumably be replaced again by his parents, raising the question of exactly what happened to Ant-Two.]]
* TooDumbToLive: All but Ant-One have even fewer self-preservation instincts than the real Anton, even being directly causing their own deaths just because some random people told them to.
* VerbalTic: Ant-Two repeats the last words of something someone else said.
** [[SelfDemonstratingArticle Something someone else said!]]

!!Mr. Cuddles

Penny's pet tarantula who was thought to have died in "The Date" (and may actually be dead from the house fire seen at the end of "The Bros," since he wasn't with the Fitzgerald family when they were standing outside). He seems to really, really hate Gumball.

* FluffyTheTerrible: Despite the name, he's a tarantula, and a fairly aggressive one.
* TalkingAnimal: Like all animals in Elmore, he showed that he could talk in "The World", but doesn't do it normally.


A strange creature accidentally created when Darwin and Gumball's "gross jar" is heated in a microwave. He eats basically anything and eventually any''one'', growing larger all the time.

* ILoveNuclearPower: Gumball claims Kenneth was created by "the atomic power of the microwave", though microwaves actually have nothing to do with nuclear radiation.
* ItCameFromTheFridge: Kenneth originated when a bunch of gross stuff Gumball put in a jar was put in the microwave.
* MiracleGroMonster: It's voracious eating habits let it keep growing and growing until, after a few days at most, it goes from approximately football-sized to two stories tall.
* MonsterOfTheWeek: Kenneth is not mentioned after "The Microwave" until he [[TheBusCameBack reappears]] in "The Finale" when Richard takes him out of storage.
* MuckMonster: Kenneth body looks like it's made of mud or sludge. Rather than being industrial waste, he's simply made of all the gross things Gumball could collect, including used tissues, bird poop, belly-button lint, and spoiled milk that was swallowed then regurgitated.
* SealedEvilInACan: In "The Finale", it turns out Kenneth was dealt with offscreen by reducing him to his original size again, putting him in his original jar, and freezing it. He's unsealed as part of the Watterson family's LastDance.
* UglyCute: In-universe, Gumball and Darwin [[AdmiringTheAbomination certainly think Kenneth, as their "son", is cute]], and Anais reluctantly describe it using these exact words. At least before he starts growing to tremendous proportions after ''eating people alive.''

-->Voiced by Kerry Shale

A [[TalkingAnimal sentient virus]] and leader of a new strain that mutated on Gumball's unwashed hand. Teri forced Gumball to wash that hand, killing all his soldiers and setting him off for revenge.

* AdaptiveAbility: It's constantly mutating, causing it to gain strange properties such as {{flight}} and infecting ''computers'' instead of people.
* AvengingTheVillain: The virus was the commander of a virus army and SoleSurvivor of Gumball washing his hands. He swears he'll avenge them by infecting and killing Gumball, his family, his friends, and everyone else until [[OmnicidalManiac "nothing is left alive on the surface of the Earth".]]
* EvilSoundsDeep: Played with; anytime it's in closeup, it's voice sounds very deep. Farther shots, however, show that its voice is extremely high-pitched from a subjective perspective because it's so small.
* ExtraEyes: It has three eyes, though given it's a virus ''any'' of the eyes are "extras".
* GutturalGrowler: It speaks with a very guttural voice.
* MonsterOfTheWeek: He's dead by the end of the episode he premiered in.
* MultiArmedAndDangerous: It has eight tentacle-like protrusion that it uses like two legs and six arms.
* NoNameGiven: As a virus, he probably doesn't even have a name.
* ProudWarriorRaceGuy: It speaks of infecting a body like waging a war and [[NobodyCallsMeChicken is extremely offended at Gumball calling it a coward]].
* UndignifiedDeath: [[{{Pride}} For the sake of proving its might]], it agrees to fight mano-a-mano against Gumball, [[TooDumbToLive who is millions of times his size]], and is immediately TrampledUnderfoot.

-->Voiced by: Jacob Hopkins

An intolerable split personality Gumball develops upon finding out his real first name in "The Name".

* AssholeVictim: [[spoiler:Gumball more or less kills Zach, albeit in self-defense and maybe by accident. Considering Zach was an independent consciousness, this might have significant moral implications... but he's such an jackass that no one gives it a second thought.]]
* CoolCat: Zach definitely ''tries'' to invoke the "confident" form of this trope, even wearing sunglasses, but everyone just thinks he's a tremendous douche. He even proudly declares that "There's a new cat in town!" shortly after appearing.
* CoolShades: He suddenly starts wearing neon-purple rimmed shades from nowhere, which [[SubvertedTrope really aren't very cool looking]], and work more like SinisterShades.
* CrazyPrepared: One genuine skill he demonstrates it planning all sorts of tricks to delay the other Wattersons, even putting a trap in his pocket for when they'd try to frisk him.
* EvilSoundsDeep: When Zach is in control, Gumball speaks in a deeper voice. However, it's so obviously affected that instead of being intimidating it just makes Zach sound like more of a poser. In his last scene in Gumball's mind, however, his voice starts getting pitched down and slightly distorted, being more of a genuine example of this trope.
* FascinatingEyebrow: He's raising one of this eyebrows almost constantly, which leads Darwin to tell him he "spent the whole day with one eyebrow raised, behaving like a horrible jock".
* IdenticalTwinIDTag: You can tell when Zach is controlling Gumball's body because he pops the ([[RuleOfFunny non-existent]]) collar on Gumball's sweater.
* IRejectYourReality: He maintains he disillusions of greatness and popularity in the face of all evidence and words of others. [[spoiler:He goes so far as to [[SelfServingMemory consciously and completely alter his memory of events]] so he'll look better in them.]]
-->'''Zach:''' Hey Carrie, I think we really nailed the song last night. We’re totally gonna win the battle of the bands, man.\\
'''Carrie:''' You’re not in a band. I’m not in a band. I bet you can’t even give me the name of a band. \\
'''Zach:''' Psh, yeah, like... Germany.
* {{Jerkass}}: Zach is amazingly impolite, has an almost pathological [[ItsAllAboutMe disregard for and lack of awareness of other people]], and literally won a contest for being obnoxious.
* JerkJock: Zach ''thinks'' he's a jock, despite not being on any sports teams, not being able to ride his skateboard well, and generally not being any more athletic than Gumball was before.
* NoBodyLeftBehind: [[spoiler:When Gumball finally beats Zach at something, bits of him start chipping off, showing a bright light in his silhouette as his torn to pieces. Although this of course wasn't really a "body" to start with.]]
* SmallNameBigEgo: For all the misplaced confidence Gumball has expressed, Zach is ''[[ADarkerMe much worse]]'' in this regard than Gumball ever was. Gumball would always acknowledges his shortcomings eventually; Zach does not and seems to believe his own hype with all his heart.
* SplitPersonality: Gumball initially seems to be acting obnoxious when he finds his real name, but Zach becomes a separate entity before he even notices.
* SplitPersonalityTakeover: [[spoiler:He attempts to do this by [[SelfServingMemory altering Gumball's memories]] until he's erased.]]
* SuperPoweredEvilSide: Played with. There isn't as much focus on Zach being evil as being a huge jerk, [[spoiler:though he really ''is'' evil, as he planned to erase Gumball's original personality so he didn't have to share]]. He's also not really that much better at most things than Gumball, he's just extremely confident and obnoxious. But when [[BattleInTheCenterOfTheMind mentally confronting]] his other, less-confident side, said confidence provides a tremendous advantage. [[spoiler:But it's also his biggest weakness, as Gumball is mentally resilient enough take losing all the time, but the one time Zach is forced to face defeat ''it literally destroys him''.]]
* SmugSnake: His boundless pride [[spoiler:directly leads to Gumball beating him.]]
* ThirdPersonPerson: Zach always refers to himself in third person, likely to emphasize he's not Gumball, and it's definitely the "arrogant" form.
* TheUnapologetic: He accidentally ''bites part of a kids face off'' and shows no regrets for it, because "Zach does what he wants".
-->''Zach doesn't apologize, he uses his charm.''
* UndignifiedDeath: [[spoiler:Zach is destroyed in Gumball's mindscape, then Gumball immediately ''farts'', his body literally [[StealthPun clearly out the hot air]].]]
