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 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.
Barefoot Cartoon Animal: Gumball, Nicole, and Richard. Anais (Who, oddly, wears socks with no shoes) and Darwin have footwear.
Voiced by Logan Grove (seasons 1–3); Jacob Hopkins (season 3 onwards)
The main character (as indicated by the title). Gumball is an anthropomorphic bluecat 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.
"What the what!?" became a semi-recurring line of his in the second season—it was even used as a Mad Libs Catch Phrase a couple times ("What the droid?", "What the wasp?") and mocked by Darwin's impersonation of Gumball in "The Sidekick".
The Cynic: 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.
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.
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 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.
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.
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.
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.
Happily Adopted/Interspecies Adoption: Darwin's treated like as much of a member of the family as Gumball is. Although legally, he's still registered as a pet. He even still sleeps in a fishbowl in Gumball's room.
Incorruptible Pure Pureness: 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".
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.
Uplifted Animal: Notably, while this can happen to anything, he's the only character stated to have become human-like rather than being born that way.
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 (pinkrabbit) 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.
The Chessmaster: 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.
Child Prodigy: 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 (even though we never see her in class, unless she's in a high class than Gumball and Darwin).
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-eye-ees and An-ai-ahs and she never favors one over the other, though, given that the character is named after Ben Bocquelet's sister and both have French heritage, it's most likely "An-eye-ees".
Only Sane Girl: Can be her or can be her mother, depending on the episode.
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 a bluecat 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).
Action Mom: She's super-humanly athletic and not afraid to get physical.
Gumball: The woman is virtually a ninja.
Almighty Mom: 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: 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.
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 pinkrabbit 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.
Hard Head: 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?
House Husband: Though he doesn't do much house work either. When he finally gets a job, it nearly destroys the Universe. He's implied to have a more significant role in taking care of the kids (or at least did when they were younger), especially since Nicole has to work a lot.
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.
A ferocious turtle that Richard bought from a van shop, thinking it was a dog.
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.
I Reject Your Reality: In "The Move" he admits he lies so much because he thinks his actual life is boring.
Poisonous Friend: Plays this to Gumball and Darwin in "The Skull," constantly including him in his lies and causing 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.
Voluntary Shapeshifting: He can change into a lot of shapes, including other people (and fake their voices as well).
Voiced by Kerry Shale
A giant covered in fur.
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".
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 presence was not commented upon.
RedheadedBully: Who does things like tears off her classmates limbs or eats part of them.
Silly Walk: She doesn't have knees, so she basically goose-steps when she walks.
Voiced by: Beatbox Hobbit (in music mode), Hugo Harold-Harrison (in voice mode)
Line Boil: Very subdued compared to most examples, but his outline shakes slightly.
The Unintelligible: 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 a long time.
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 ambiguous homosexuality, unlike most characters who have been labeled as such, can be explained in that most flowers have male and female reproductive organs, so it would make sense for someone like Leslie to be an effeminate male.
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.
Barefoot Funny Animal/Fully Dressed Cartoon Animal: 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.
Beary Friendly: 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.
The Chew Toy: She becomes victim to an incredible amount of physical trauma in season three, likely because being made of paper makes it all Bloodless Carnage. 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.
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.
Motor Mouth: When something cause her to talk about disease, Teri tends to go on a detailed clip without any letting anyone else talk.
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.
Casanova Wannabe: 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.
Not a Zombie: 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).
In "The Mystery" 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.
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. And it all gets stuck to him.
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: Usually he's not, 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. Word of God and the episode "The Sock" reveal that his relationship with Miss Simian is cutting into his professionalism.
The Cobbler's Children Have No Shoes/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 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.
Accessory-Wearing Cartoon Animal: 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.
Fat Idiot: 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 weight.
Drives Like Crazy: 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!").
Expy: He has a lot in common with Chief Wiggum from The Simpsons, though Doughnut Sheriff is slightly more competent than Chief Wiggum is. They're both even voiced with an Edward G. Robinson impression.
That Man Is Dead: 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.
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)
The Watterson's cranky neighbor who appears to be a sort of muppet creature. In spite of his attitude, Gumball and Darwin adore him.
Cranky Neighbor/Grumpy Old Man: 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.
Hidden Depths: Despite his uptight personality, he has a love of dance, and gives a big musical performance in his first episode.
Hopeless With Tech: 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.
Lookalike Lovers: 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.
Your Cheating Heart: 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.
Voiced by Lewis MacLeod
Mr. and Mrs. Robinson and a muppet creature like his parents. He works numerous non-teaching positions at Elmore Junior High.
American Accents: He had a slight Dixie accent in the first season. Season two on, he had a stereotypical hippie voice.
Chew Toy: Him being injured as the result of the protagonist's actions is starting to become a Running Gag.
Cloudcuckoolander: Even besides his deliberately "hippie" behavior, he's done strange things like writing extremely long poem from the point of view of a shoe and thinking he reached enlightenment when he woke up in a room full of foam.
Drill Sergeant Nasty: He's the judge for cheerleading tryout and is extremely serious about it for a team with about six members.
Mood-Swinger: Can go from an easy-going hippie to an enraged maniac in a snap.
New-Age Retro Hippie: 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 Janis Joplin), and even being a literal cloud. There's even a few moments implying he is indeed a stoner (drinking herbal tea that makes him black out and his line on "The Void" where he explains why he's good at traveling through the dimension of the world's mistakes: "I'm used to being spaced out.")
Nothing but Skin and Bones: On a few occasions where he wears skin-tight clothes we can see his ribcage with a disturbing amount of detail. Justified as he is (was?) on a diet of nothing but sunlight and ended up starving himself.
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 so he can rub his superiority over not eating meat in everyone's faces. 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.
Girls with Moustaches: She's technically bald-headed and has 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", showing she had not noticed before.
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.
The Nicknamer: Calls Gumball "the blue one" Darwin "walking fish" and "fish kid".
Obnoxious In-Laws: 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.
