The main character (as indicated by the title). Gumball is an anthropomorphic blue 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.
Attractive Bent-Gender: When he's forced in a dress, everyone instantly likes him and calls him beautiful. It helps that he takes after Nicole.
Badass Pacifist: Along with Darwin in "The Sweaters", as they refuse to engage the students from the other school in their idiocy. What makes them win in the end; they didn't even try to beat the bad guys.
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.
Deadpan Snarker: He gets increasingly snarkier as the show goes on, especially regarding Darwin. It becomes especially apparent throughout the second season, and compliments his Vocal Evolution (see below) quite nicely, actually. The most obvious example would be "The Bumpkin", where his cynical outlook on modern society is a primary plot element.
Depending on the Writer: 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 Only Sane Man. Since the latter half of Season 2, his Only Sane Man status became the more distinct of them all.
Detachment Combat: Without the combat though, but Gumball seems to be able to function perfectly whenever a body part gains autonomy.
Determinator: In "The Third" he rides a tricycle for 140 kilometers, 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.
Embarrassing Middle Name: "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.
Master of None: One episode establishes him as having literally no talent.
No Sense of Direction: 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.
Strong Family Resemblance: 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.
Twice Shy: With Penny. Their feelings are mutual, but both struggle to confess to each other.
Verbal Tic: He tends to squeak, usually when he's yelling. Some of this just seems to be due to Logan Grove's voice cracking.
Vocal Evolution: Along with Darwin, his voice got deeper over the course of the first two season as his VA got older.
Voiced by Kwesi Boakye (season 1–3); Terrell Ransom, Jr. (season 3 onwards)
Gumball's pet goldfish-turned-family member after it 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. Darwin is a bit naive due to his forced adaptation among the "normal" world, though he is more rational and moral than Gumball.
Adorkable: More so in season 1, where his naivete is played up more often than Gumball's.
Badass Pacifist: Along with Gumball in "The Sweaters", as they refuse to engage the students from the other school in their idiocy. What makes them win in the end; they didn't even try to beat the bad guys.
Bad Impressionist: 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, Mrs. Mom, what's for dinner? Nicole: (unconvinced) Really? Darwin: (defeated) Y-ep.
Bad Liar: Neither he nor Gumball could resist darting their eyes to the side when lying to Anais.
Beware the Nice Ones/Beware the Silly Ones: 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.
Big Eater: At least, he tends to think with his stomach from time to time as most fish seem to do.
The Conscience: He has a higher moral sense than Gumball does. In "The Sidekick", Gumball tells him that he counts on Darwin to stop him from going through with especially bad ideas.
Deadpan Snarker: Well, usually his snarking is a lot more cheerful, but he gets more and more of it after the first season.
Depending on the Writer: 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 Beware the Nice Ones.
Deuteragonist: He has at least a secondary role in more episodes than anyone but Gumball.
The Ditz/Genius Ditz: Like Gumball, he's not very smart except when it comes to some very specific things, and becomes more intelligent later on.
Only Sane Man: 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 Straight Man 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.
Overly Long Name: In "The Party", he reveals that his full name is Darwin Radlin Caspian Ahab Poseidon Nicodemus Watterson III.
Sarcasm-Blind: In season 1. In season 2, he snarks with the best of them.
Speech Impediment: In "The Sock," Gumball points out that Darwin has a lisp where his gills whistle. Darwin retorts with "You're so stinky, sailors sing sea shanties about how stinky you are!" making a whistling sound with every 'S'. This only happens for that one and only time, though. In fact, the very next sentence he says contains 'S'es without the lisp.
Stepford Smiler: 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.
Took a Level in Jerkass: Invoked in "The Words", where Gumball advises him to be more direct with his opinions, which results in insulting everyone, and being proud of it. 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.
Vocal Evolution: Along with Gumball, his voice got deeper over the course of the first two season as his VA got older.
Voiced by Kyla Rae Kowalewski
Gumball's genius little (rabbit) sister, who is his junior by eight years (Gumball is 12, she is 4). Due to her high intelligence, she attends Gumball and Darwin's middle school as well. Despite her competency, she still displays some traits of a typical four-year old.
However, in "The Goons", she was seen briefly not wearing (at least one of her) socks. Also, in "The Castle", she's wearing magenta footless pajamas for most of the episode, making her a Barefoot Cartoon Animal.
Grade Skipper: She's 4, and attends the same middle school as her brothers.
It Is Pronounced Tro-PAY: Subverted. Her name is pronounced both as An-ai-ees and An-ai-ahs and she never favors one over the other. Given that Ben Bocquelet (the show creator) is French-British and named the character after his sister, the proper pronunciation of is "An-ai-ees," and the proper spelling is with two dots over the "i" (ï) to indicate two separate long vowel sounds (a long "i" as in "high" and a long "e" as in "piece").
Pint-Sized Powerhouse: She is depicted as being able to life way more than her body weight at a very young age at that. 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.
Not so Above It All: She's considerably more child-like—or even flat out crazy—when it comes to anything involving Daisy the Donkey.
Straight Girl: Usually. She's the most serious character on the show, but sometimes she slithers away from this.
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.
The maternal member of the Watterson family (and the same kind of cat as 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).
Action Mom: She's super-humanly athletic and not afraid to get physical.
Gumball: The woman is virtually a ninja.
Amazingly Embarrassing Parent: 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".
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 Only Sane Man.) She tried to pull a I Surrender, Suckers 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 Loophole Abuse.
Control Freak: 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. Although she's right that there's a bigger problem with that: namely that Richard having a job will destroy the universe.
Cute Bruiser: Don't make her mad. She is a lot stronger than she looks.
Doting Parent: When her kids aren't doing something reprehensible, she can be quite coddling toward them, especially in "The Meddler".
The Dreaded: 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.
Hair-Trigger Temper: 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.
Hartman Hips: Not including her head, her hips are the widest feature of her body.
Hulking Out: 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 required no such musculature.
Killer Rabbit: 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.
Shipper on Deck: Judging from "The Meddler" and "The GI", she seems to root for Gumball/Penny. Possibly it's because Penny reminds her very much of herself in her childhood when she had a crush on Richard and defended him.
Super Weight: Unclear where she lies on the scale. At first glance appears to be 1, but some incidents, such as beating up Tina Rex's father (despite being 1/100th his size) suggests it may be higher. The nature of her power is unclear other than it appears to be fueled by anger.
Unstoppable Rage: She has tremendous Super Strength, but apparently only when she's angry. In "The Club", she even has to ask her family to enrage her somehow so she can pull a door open.
Voice of the Legion: When sufficiently pissed off, her voice gets really deep as well as echoing.
What Does She See in Him?: 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.
Women Are Wiser: 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".
Voiced by Dan Russell
Gumball's father and Nicole's 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.
Amazingly Embarrassing Parent: 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.
Ax-Crazy: In "The Prank" after the kids prank him one too many times, he goes completely psycho with Slasher Smile chasing them all over the house. It turns out that making them think he went insane was his way of pranking them.
The Ditz: It's easier to count examples of when he doesn't act like one.
Drives Like Crazy: 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 which Gumball considered an improvement.
Freudian Excuse: 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.
House Husband: Though he doesn't do much house work either. When he finally gets a job, it nearly destroys the Universe.
Huge Guy, Tiny Girl: He's something like half a head taller than Nicole and several times as large.
Sleepyhead: Most commonly seen sleeping on the couch.
Stout Strength: Apparently has this, as shown in "The Remote" when he effortlessly rips the car door off to get to Nicole.
Straw Loser: 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 place any responsibilities onto him.
Walking Techbane: Judging from how automatic doors, elevators, and self-checkout scanners treat him.
With Great Power Comes Great Insanity: Parodied in The Wand. He thinks he has Power, when it's actually Gumball and Darwin moving along with it so he wont have his childhood dreams crushed. They eventually have enough since it goes overboard.
Ax-Crazy: His entire existence is biting. He eats for strength to bite. He reproduces to have more turtles who can bite.
For the Evulz: 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!
Long Neck: It can extend its neck something like a foot out of its shell.
Nigh-Invulnerability: 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. And 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.
No Name Given: The Watterson's never gave it a name; they're too busy being terrified by it.
Pintsized Powerhouse: Its size doesn't keep it from pulling around full-sized people, though it does make it easy to pick it up.
Poisonous Friend: Plays this to Gumball and Darwin in "The Skull," though 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.
Voluntary Shapeshifting: He can change into a lot of shapes, including other people (and fake their voices as well).
Voiced by Kerry Shale
Art Evolution: 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".
The Generic Guy: His mother was intentionally keeping him this way so he would never get emotional and go on a rampage.
Cartoon Creature/Mix-and-Match Critters: 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 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.
Informed Ability: The reason for her bullying is because Ms. Simian held her back a year so she developed an extreme resentment for authority and her new classmates. You wouldn't know that due to her background appearances.
The characters page on the official website describes her as Tina's sidekick, but the two were only shown working together once in "The Fight" where Jamie's was no commented upon.
The Unintelligible: He speaks 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 a long time.
Leslie the Flower
Voiced by Kerry Shale
Ambiguously Gay: 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.
The Cheerleader: She is, technically, a cheerleader. But the malicious version described in this trope is averted.
Genre Blindness: In "The Storm", when Alan is in danger as Masami becomes Yandere and literally becomes a living tornado which abducts him, Carmen tells Gumball to save him only for Penny to stop him and decides to do it herself because Gumball made Alan and Carmen's relationship complicated despite him trying to fix it. But because she is not the protagonist nor the character focus of the episode which are Alan and Carmen, she gets hurt for her effort and changes her mind for Gumball to do his part.
Verbal Tic: She tends to repeat the last word she hears.
Teri the Paper Bear
Voiced by Teresa Gallagher
Bears Are Bad News: Not the case even if she wanted it to be, as she has about the strength you'd expect out of a crumpled piece of paper.
Face Doodling: 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). Her paper body gives her the capability of erasing face doodles quite easily.
Ill Girl: Or at least that what she's worried about being.
Jerkass Façade: It is revealed in "The Fight" that she isn't really a bully, 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 Does Not Know Her Own Strength.
Jerk Jock: Although he is nicer after "The Third".
Not a Zombie: Inverted in "The Joy", as being ignored by all the girls with the happiness virus that makes you rainbows left him the only one note infected, but his technicolor appearance made Miss Simian think he was anyway (possibly that's why none of the male infected bothered him either).
Voiced by Lewis MacLeod (Season 1) Stefan Ashton Frank (Season 2)
Berserk Button: 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.
Cartoon Creature: "Furry slug" is the most accurate description of what exactly he's supposed to be.
Humiliation Conga: He's quite prone to these. It first happens to him in "The Mystery" where he was slammed with a door 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.
Happens again in "The Meddler', where 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.
Phony Degree: "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.
Reasonable Authority Figure: 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.
The Cobbler's Children Have No Shoes/Hypocrite: She's in charge of physical fitness and goes on about how necessary it is, yet but she's in such terrible shape (literally and figuratively speaking) that she gets exhausting running even the shortest distance. On the other hand, her daughter is very physically fit.
Lady Looks Like a Dude: 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. Specifically, she's Jamie's mom.
Why Do You Keep Changing Jobs?: Runs pretty much every shop in town. Lampshaded 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.
Voiced by Rupert Degas (Season 1) Stefan Ashton Frank (Season 2)
Piss Take Rap: Has one about honesty; while dressed in a bear costume.
Scare 'Em Straight: 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.
Straw Vegetarian: In "The Castle" he states he's only a vegetarian for the feeling of superiority.
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.
And yet she has also shown to not be COMPLETELY heartless 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 behaviour, she just chuckles. It's a surprisingly sweet moment for such a mean character.
