!!The Pack
[[folder:Adam M. Lyon]]
->Voiced by: Creator/NikaFutterman

A human boy who was transferred from Chester Arthur Middle School to Charles Darwin Middle School by an accidental misspelling of his last name from "Lyon" to "Lion".
* AdamAndOrEve: It can be perceived that Adam, being the first human male in an all-animal environment is a biblical reference.
* {{Adorkable}}: Adam is shy and usually awkward in social situations, but he sure is cute.
* AesopAmnesia: Episode upon episode, he's told to stop complaining about being the only human at his school, but he instantly forgets it by as soon as [[StatusQuoIsGod the airing of the next episode]].
* TheAllAmericanBoy: It's been implied that he acted like this, back when he still went to a human school. Some overflow was seen at the beginning of "The Morning Zoo", he was seen, greeting the day with a flamboyant "Gosh, golly gee! What a happy sunshiney day!"
* AnimalMotifs: Adam's learned how to embrace his so-called "lionhood". Being mistaken for and treated like a lion all his life has led him to take on the roles and abilities of said animal pretty well.
* {{Animorphism}}: Several episodes involve him either turning into an animal or embodying the [[AnimalJingoism jingoism]] of said animal.
* TheAnticipator: In the Season 4 episode, "Mountain Dude", he started expecting things to happen when the first sign showed itself.
--> '''Adam:''' [[FourthWall Well, here we go again, kids]].
** Oddly, Jake predicted plot lines coming as early as two seasons earlier, in "I Got a New Aptitude".
* AwesomeMcCoolname: "Lion" spelled with a "y" is a pretty kick-ass sounding name, when you think about it.
* BadJobWorseUniform: Had to dress as a sign-twirling gorilla in "Flesh Fur Fantasy".
* BeingHumanSucks: For this guy? I'd bet.
* BerserkButton: After dealing with repeated torture from Jake, Pixiefrog, or CDMS in general, Adam will often lose his mind in the climax or ending of a few episodes.
* BewareTheNiceOnes: For the most part, a polite and sweet kid, but if you deny his due respect and treat him like crap a lot (and I do mean a lot), he will go from sweet to sour and kick your butt.
* BirthdayHater: Has always tried distancing himself from celebrating birthdays ever since [[NoodleIncident that time he wet his pants at his birthday party in first grade]].
* BodyHorror: [[HumiliationConga At the end of "Hyena and the Mighty", Adam gets beat up by random machines after threatening Rufus to stop crying and Adam's beating makes Rufus laugh and results in Adam getting injured and bruised.]] [[LaserGuidedKarma To be fair, he deserved it for the massive jerk he was being to Rufus.]]
* ButtMonkey: He constantly gets in trouble for Jake's misbehavior, gets hurt a lot, has bad luck, gets picked on by Bull and Chad, etc. You know the drill.
* TheBore: He became this in "Wild Thing", where his friends, teachers, and even bullies would be driven mad by his long, drawn out tangents about his personal life, internal struggles, backstories, etc.
* CasualDangerDialogue: Made a few of these in "Mountain Dude".
-->'''Adam:''' ''[happily]'' I told you something bad was gunna happen!
* CharacterDevelopment: He's not only grown more accustomed to his animal school, but he's embraced it. In late season 3 and season 4, there are also episodes, where he stops playing the straight man and acts just as goofy as Jake and Slips, if the episode were to focus on the problems happening with another character, such as Windsor or Ingrid.
* CharacterizationMarchesOn: However, that didn't stop him from having [[AesopAmnesia Aesop amnesia]] in a few later episodes, with him once again, babbling on and on about how he's the only human and he misses his old school, [[BlahBlahBlah blah blah blah]].
* TheChewToy: Most of his haplessness is played for comedy.
* TheCheerleader: Involuntarily became one in "Cheer Pressure".
* ChickMagnet: He became this in "I Got Rhythm". Also in "The Frog Principal", but only because of a [[LovePotion love potion]].
* ChillyReception: Adam being new to the school, means he lacks knowledge on important information all other animals need to know. He suffers the consequences of not taking whatever precautions are needed to be taken in order to handle whatever conflict may be headed his way, and the other animals never tell him about it beforehand, because it's such a basic and natural part of their lives, they don't give it enough attention to consider, whether Adam knows it already or not.
* CoconutMeetsCranium: Got pelted by coconuts at the end of "She's Koala That" for making too much [[JustForPun lame puns]].
-->'''Adam:''' Can someone koala doctor?
* CollectorOfTheStrange: Collects weird [[ShowWithinAShow Captain Clowny]] merchandise and takes it to extremes. He even has a Captain Clowny grandfather clock in his room, which he uses as his regular alarm.
* ComedicUnderwearExposure: It's become a running gag for Adam to be seen in his Captain Clowny underpants.
* TheConscience: To Jake, but he's never listened to.
* ContinuityDrift: In "Where in the World Are Adam's Parents?", Adam said his parents were deathly allergic to all non-human animals. This would make it virtually impossible for Adam to have a house pet without killing them. However, in "Synch or Swim", he said he used to have some pet sea simians.
* CoolLoser: One of his main character traits.
* CowardlyLion: Adam is a Cowardly Lyon.
* CrossDresser: Dressed as female pop star, Truffles Duvall, to win Jake's friendship back in "The 'A' Word".
* DeadpanSnarker: Pays to be this if you're the OnlySaneMan of this school.
-->'''Orlando:''' (squawk) Pretty bird!
-->'''Jake:''' Pretty monkey!
-->'''Adam:''' (deadpan) Pretty stupid.
* DidNotGetTheGirl: Endings to plots with Kerry consistently zig-zag from this, to the opposite.
* DoesNotLikeSpam: Utterly disgusted by the cafeteria food, but this is only because they're not intended for human consumption. Menu items would consist of dirt, live bugs, twigs, mud, and other disgusting things that only an animal could tolerate.
* DogWalksYou: Inverted in "Human Behavior", when Adam transcended into a state of being an animal and Jake had to walk him on a leash, only to get pulled down the sidewalk.
* DoomMagnet: Almost anytime something bad happens at CDMS, Adam is at least somewhat troubled by it.
-->'''Jake:''' When was the last time something bad ever happened around here?
-->'''Adam:''' Uh, ... every day?
-->'''Jake:''' Let me rephrase that. When was the last time something bad ever happened to someone, who's not you.
-->'''Adam:''' Good point.
** A few episodes give Adam a break, like "The Sheds", "Oh, Henry!", "Four Eyed Jake", "Ingrid Through the Out Door", and "The Morning Zoo", which instead torture other main or recurring cast members for a change.
* EatingPetFood: Pretty much every time he forgets to bring his lunch. Best expressed in "Chew on This".
* EstablishingCharacterMoment: In the first episode, Adam was sitting on the bus, arms folded, and scowling, while Jake was sitting on his head and picking fleas out of his hair. His first quote set his character for the show.
-->'''Adam:''' Whoever said humans and monkeys share the same genes is an idiot.
* TheEveryman: Adam is the Mr. Normal of the cast, making himself the most relatable to the show's target audience.
* EveryoneHasStandards: He thought it was fairly reprehensible of Lola Llama to try and steal Ingrid's life away.
* EvilHand: Stupid Hand.
* ExpositoryHairstyleChange: In "Political Animals", he underwent the same hairstyle change as Bill Mckay from Film/TheCandidate for the same reasons.
* FacePalm: Tends to do the forehead slap a lot.
* FailureHero: Most of the time.
* {{Fanboy}}: Of Captain Clowny.
* FatalFlaw: Adam's main character flaws would be his physical and emotional weakness, his constant whining and complaining, and in later seasons, his unbridled narcissism.
* FieryRedhead: ... You could call it that ...
* FirstKiss: [[spoiler:He and Kerry kissed as babies on Thanksgiving one year.]]
* FishOutOfWater: Even the beached aquatic students possess more street-wisdom than him.
* {{Flanderization}}: In the latter half of Season 4, episodes featured Adam Lyon being a walking ball of self-absorbed, egotism, who couldn't shut his face about his personal life for two seconds and was completely blind to the world around him.
* FlopSweat: Had this in "Kerry to Dance?", when working up the nerve to admit he liked Kerry ... to Jake!
* FourTemperamentEnsemble: Sanguine.
* FreeRangeChildren: His parents are [[ParentalAbandonment almost entirely absent]], both leaving for work at 4:00AM and not coming back until well after dark on a daily basis. This, and they are strictly obligated to ever go to his school, due to their animal allergies. Adam's learned to fend for himself, earning him the independence to do just about whatever the hell he wants without parental punishment.
* FriendToAllLivingThings: Friends with a very odd array of exotic animals.
* FullFrontalAssault: His tendency to both getting attacked and stripped down to his undies, joined forces in "Glazed and Confused".
* GoofyPrintUnderwear: Adam has underwear with a picture of Captain Clowny's face in the butt, with a real red nose, that actually honks, when squished.
* TheHero: The closest this show has to one.
* HeterosexualLifePartners: With Jake.
* HumansAreInsects: Despite being the smartest species, and a bit of a novelty at his school, Adam is still looked down on for being human. In "Lyon of Scrimmage", Coach Gills referred to him as the most Un-Athletic species CDMS has.
* HumanHammerThrow: Adam and Jake's unique Ultimate Fetch move is the reversal of this.
* HumiliationConga: Happens to him at the end of "Hyena and the Mighty."
* IJustWantToBeNormal: Wishes he went to a normal school without a bunch of animal students.
-->'''Adam:''' I wish my life was boring. I wish my life was boring. I wish my life was boring...
* IconicOutfit: Mustard yellow T-shirt and green cargo shorts.
** Jake listed off his other recurring outfits in "A Whole Zoo World". These would be his Captain Clowny underwear, cheerleader uniform, and [[GagCensor naked with a fig leaf]].
* ImAHumanitarian: In "Where in the World Are Adam's Parents?", people were assuming that Adam has eaten his parents, since [[InvisibleParents they've never been seen]]. This turned out to be a lie, but at the end of the episode, as always, they needed to [[EverybodyLaughsEnding end it off with a joke]]. In this case, it would be Adam burping up a human bone, [[BlackComedy humorously suggesting that he was a cannibal]], who may not have eaten his parents, but at least he's eaten someone else.
* TheInsomniac: Numerous times, actually. In "Up All Night", Adam's friends kept him [[ExactlyWhatItSaysOnTheTin up all night]] at a sleepover, eventually making him go completely nutty. In "Human Behavior", Adam stayed awake for three weeks straight, to practice for an animal behavior test, which eventually got to his head, and turned him into a feral freak. This wouldn't be the first all nighter he pulled, as once again, a properly titled short, "All-Nighter" included Jake on the fun, where they both stayed up all night, to for the following day's hibernation test.
* InstantChucks: Pulled nunchucks out of thin air in "Nice Mustache".
* InterspeciesRomance: Has wound up in relationships with Latanya, Margaret, and Joanie.
** Not to mention the countless animals who have a crush on him, Ingrid Giraffe, Latanya Hippo, Margaret Rhino, Joanie Ox, Nurse Gazelle, Lola Llama, Kimberly Capuchin, The Ghost of Thanksgiving Past, every female teacher in "Poop Scoop", and every female student (including Nurse Gazelle again) in "The Frog Principal".
* ItGetsEasier: Season 4 episodes like "Human Behavior" and "A Very Special Boy" show him getting used to and even embracing the madness of Charles Darwin Middle School.
* JerkassBall: "The Hyena And The Mighty".
* JoinsToFitIn: Adam's undying need for a group of human friends is born of him being the human of his pack. Of course, [[StatusQuoIsGod the status quo is god]] in this show, so he's never gunna find a friend group that'll stick.
* JumpingOffTheSlipperySlope: "The Hyena And The Mighty"; his abuse of Rufus Hyena. Particularly the scene where he threatens the hyena with physical violence to stop crying.
* KickTheSonOfABitch: See BodyHorror above.
* KiddieKid: Gets very excited over Captain Clowny, a [[ShowWithinAShow in-universe cartoon franchise]] generally seen as a baby show.
* KingKongClimb: In "Inoculation Day", Adam turned into a monkey and climbed up Ingrid, while holding Principal Pixiefrog, who was wearing a mop as a wig at the time.
* LaserGuidedKarma: In "The Hyena and The Mighty", Adam was sick of Rufus Hyena's insensate laughing and made him cry by insulting him, despite [[HowMuchDidYouHear not knowing he was in the room at the time]]. He was shamed by everyone in the school and later got brutally beaten sore by a [[RubeGoldbergDevice Rube Goldberg machine]], causing him to cry. People saw this as his getting what he deserved for being such a Class-A douchebag, but nobody acknowledged how Adam bent over backwards, trying to make up for what he did all episode long. Not did they realize how Adam's hatred for Rufus stemmed from how his laughter often came from harmful pranks that came at his expense.
* LongDistanceRelationship: Technically, his relationship with Kerry, due to the school transfer, however, she does live right next door to him.
* LoserProtagonist: Adam is a social outcast, who pretty much fails at everything he tries.
* LoveGoddess: Accidentally became a male variant of this, when he paired up Lupe and Orlando together.
* LoveInterest: Kerry Anderson.
** [[LoveTriangle He's also the apple of Ingrid's eye]].
* LoveMakesYouDumb: Adam can do a lot of stupid things, just to impress Kerry.
* LimitedWardrobe: Adam's entire closet is full of mustard yellow shirts and green cargo shorts.
* MeaningfulName: His first name is a biblical reference. Adam from the bible was the first human man, placed on a planet with it's only other inhabitants being animals. Meanwhile, Adam from the show is the first human boy, sent to a school, with it's only other students being animals.
* MonsterMisogyny: Lampshaded in "Inoculation Day", when he turned into an ape, and attakced Principal Pixiefrog, because he had a mop on his head, which made him look like a lady.
* MouthyKid: Makes condescending comments about Principal Pixiefrog's dumb ideas.
* MyGodWhatHaveIDone: Had his fair share of moments, where he went dangerously close to the [[MoralEventHorizon moral event horizon]], but he's always managed to just barely redeem himself in the nick of time.
* MysteriousMiddleInitial: It's never leaned what "M" stands for.
* NaiveNewcomer: To CDMS, obviously.
* TheNapoleon: He's in middle school and is short and stout.
* {{Narcissist}}: Mostly yammers about his own personal problems and sees himself as the center of attention. Adam showed hints of this in seasons 1-3, but was still selfless enough to feel sympathy for other characters and go out of his way to help them. However, in Season 4 his egotism was [[UpToEleven wildly maximized]] and episodes centered around him being completely blind to everyone except himself.
* NewTransferStudent: The basic outline of his character.
* NiceGuy: Technically, who he is, but since his school pushes him [[RageBreakingPoint past his limit]] in mere seconds, every episode, we rarely get to see this side of him.
* NoisyShutUp: The only way he can be heard.
* NotAllowedToGrowUp: Over the course of 4 real-life years, Adam has still managed to stay an 11 year old boy in 6th grade, with every passing episode taking place on his first year at Charles Darwin Middle School. The writers worked around this nicely, by only having episodes take place on a specific day once. (i.e. there's only one Halloween episode, one spring break episode, one Thanksgiving episode, etc.) Granted, these episodes are out of order, with Thanksgiving taking place 3 seasons after Halloween and spring break being in between the two, but [[AnachronicOrder there, we can just say the series is an "anachronic order" show]] and every episodes takes place somewhere within the same year.
** He possibly turned 12 in "Supplies Party", but since no numbers were mentioned in dialogue, it can be said this was an [[AgelessBirthdayEpisode ageless birthday episode]].
* ObfuscatingStupidity: Pulled this off, to escape the advanced learning class.
* ObliviousToLove: No matter how obvious they may be, all of Ingrid's hints that she loves Adam go right over his fiery little head.
* OhCrap: Says "Oh, Poopy." in these situations.
* OnlySaneMan: ''Literally,'' and figuratively.
* OpinionFlipFlop: Pretends to like stupid crap like fake mustaches, Jiminy Japoopy music, and school plays, just so he and Kerry can have something to do together.
* OrdinaryHighSchoolStudent: In this case, middle school. Adam plays the role of the series' "everyman", acting as normal and down to earth as he possibly can, while existing in a high-case scenario of a bunch of talking zoo animals, driving him insane at CDMS. For the most part, he tries to maintain the profile of the school's literal and figurative [[OnlySaneMan only sane man]], but due to [[SanitySlippage sanity slippage]], he mostly winds up as the "only man" among a plethora of other wackos, who are just as zany and deranged as him.
* ParodySue: At his old school, he was a perfect example of a popular boy, with straight A's, and a life that was just heaven on earth. The writers did this on purpose, to make it all the more hilariously painful for Adam, when he got transferred to his new school.
* PhotographicMemory: Adam was able to memorize football plays, word for word, after taking one look at the rule book in "Lyon of Scrimmage".
* PirateParrot: Wore this as his Halloween costume in "It's the Scary Old Custodian, Adam Lyon".
* PositiveFriendInfluence: Especially to Jake. His friends' lives would have a lot more problems and a lot less solutions if it weren't for him helping them out.
* PottyFailure: It was learned that he wet his pants at his 6th birthday party and Chad still won't stop giving him Hell about it. On his 12th birthday, the [[HistoryRepeats exact same thing happened again]].
* ThePrankster: Unintentionally became this in "Pranks for the Memories".
* ProtagonistTitle: Technically, he is the "My" in the show's title.
* PungeonMaster: At the end of "She's Koala That".
-->'''Adam:''' I've been thinking of becoming a marsupial, but I don't think I meet all the koala-fications for it.
* RageBreakingPoint: From time to time, this happens, but the most notable incident comes from "A Very Special Boy", when Principal Pixiefrog gave him an [[InnocentlyInsensitive innocently insensitive]] [[ReasonYouSuckSpeech reason you suck speech]].
* RapidAging: In "The Two Jakes", genetic clones of himself and Jake were crafted and went from 11 year old boys, to 90 year old men.
* RealMenWearPink: He can be rather effeminate at times and has been noted to have a rather girly voice.
* RedHeadedStepchild: Though, the fact that he's a ginger usually has nothing to do with his loserdom, it is a running gag for people to poke fun at his hair color.
* RedheadsAreUncool: In "Wild Thing", it was a running gag for people to think [[JustForPun his head was on fire]].
* RidiculouslySuccessfulFutureSelf: In "I Got a New Aptitude", he assumed he'd one day be a firefighting, spacewalking president.
* RookieRedRanger: Despite being the new kid and all, he's always the one who figures out how to solve the problems.
* SamaritanSyndrome: He's got a knack for helping his friends out, when they're in a jam. Over the seasons, he's done this so often, he's been the go-to guy for even the teachers, and it's now basically become his job at the school.
* ScreamsLikeALittleGirl: Adam has it so bad, that he actually used this as a power in "A Very Special Boy".
--> '''Adam:''' Remove my special protected status, OR I'LL SCREECH MY FURLESS, PASTY, NAMBY PAMBY, CARGO-PAINTED, LUNGS OUT!!!
* SensitiveGuyAndManlyMan: Sensitive Guy to Jake's Manly Man.
* TheShadowKnows: In "Where In the World Are Adam's Parents?", Adam was perceived by Jake, Slips, and Windsor as a parental murderer. When Adam was pleading innocent and holding a lint roller, a shadow of his was cast on the wall, depicting him with devil horns, and the lint roller was more dagger-shaped.
* ShellShockedVeteran: In "Human Behavior", CDMS defined his personality, when he went full-on [[{{Animorphism}} animal]] and could no longer cope with the outside human world.
* ShrinkingViolet: Afraid to tell Kerry that he loves her.
* SingleTargetSexuality: Possibly doesn't have eyes for anyone, except Kerry.
* SpeaksFluentAnimal: Which is normal in this universe.
* StrangerInAStrangeSchool: A human boy accidentally sent to an animal school.
* StrollingThroughTheChaos: Every walk down the hallway for him.
* StubbornHair: In "An Inconvenient Goof", his hair is shown to inflate to improbable proportions, in cases of intense humidity.
* SweepingAshes: It's happened to him enough for him to eventually realize the harmlessness of getting burned to a crisp in "A Very Special Boy".
* SuicideAttack: Attempted this in "A Whole Zoo World", but didn't die, of course.
-->'''Jake:''' Adam? Are you okay? [[NeverSayDie Remember, this is a kid show]].
* TokenHuman: The only human of Charles Darwin Middle School.
* TraumaticHaircut: Did a number on himself in "The Cuddlemuffins".
* WantingIsBetterThanHaving: He had this in one episode when he temporarily went back to his old school, finding Charles Darwin Middle School to be more fun and interesting in comparison.
* VanityIsFeminine: For some reason, in "Ingrid Through the Out Door", a [[RunningGag running gag]] involved the pack being weirded out by Adam's admiration for a picture of himself. If it's not because they were turned off by his narcissism, then maybe this might be the reason for their unhappy reactions?
* WeakButSkilled: When he became the school quarterback, we was too much of a weakling to throw a ball more than a few feet. However, he had the football plays down pat.
* WhatCouldHaveBeen: [[InUniverse In-Universe]], if Adam was never taken from his normal school, and that damn clerical error just never cane about, he would have a happily normal, almost perfect life, and a bright future, full of success and good fortune. [[spoiler:Just his first year at CDMS alone, thoroughly changed him, as in it absolutely fucked him up. He's lost grip with his human nature, sullied his [[MarySue perfect character]] with personality flaws, and is destined to spend the rest of his life, working as a zoo animal, who literally sits in a prison-like cement room]]
* WhiteMaleLead: Of all the choices from the area's, rich and diverse student body, complete with Blacks, Asians, Latinos, etc. of course, a white guy, was chosen. Believe it or not, this is also lampshaded, but they refer to his skin color as "pink".
** The whole "pink" thing is a reference to how some cultures (including the U.S.) used to refer to white people as such, due to the slightly pinkish undertone in their skin.
** Likewise, black people used to be called "brown", for the same reasons. So, maybe it's good they didn't chose a black kid to be in that position, then.
* WiseBeyondTheirYears: Precocious for his age and was a A+ student at Chester Arthur. He also usually corrects Principal Pixiefrog, when he makes stupid decisions and he's always in the right.
* YouHaveGotToBeKiddingMe: Uses stock phrases like "Oh, come on!" and "Seriously?" along with him slapping his forehead. With Jake being his best friend, and his principal being an idiot, running an already ridiculously unconventional school, the situation calls for it a lot.
* YouthfulFreckles: Because he has red hair.
* ZanyScheme: Despite Jake obviously being the mastermind behind these, the gang (including Jake) turned to Adam for zany advice in "Don't Noc It 'Til You Try It". To be fair, despite Jake coming up with these plans, Adam usually puts them into action.
[[folder:Jacob "Jake" P. Spidermonkey]]
->Voiced by: Creator/TomKenny

A spider monkey who quickly became Adam's best friend. He is often very possessive of Adam and hates not having him around regularly. Jake is emotional and goofy who takes to heart some of Adam's comments and actions, leading to some overly dramatic and exaggerated reactions. He can be lazy and selfish, but at the same time he is also fairly sensible.
* AbnormalLimbRotationRange: Jake's able to stretch his butt out to the front of his body to hug it, and can bend his head backwards, so he can get a good look at it.
* AbsenteeActor: Had no lines in the short, "Bathroom Break".
* AcquiredSituationalNarcissism: In the comic book issue, "The Color of Monkey", which served as a [[SequelEpisode sequel episode]] to "The Notorious Windsor Gorilla", the same basic plot from the latter was done again, only with Jake in the place of Windsor.
* AddictionPowered: Jake appears to be fueled by his love for his butt. As shown in "The Butt of the Jake", he lives and breathes off of it, and without obsessing over it every 5 seconds, he'd probably go insane.
* AfraidOfNeedles: Made this more than obvious in "Inoculation Day".
* AmbiguouslyGay: Jake appears to like Adam as a bit more than just his best friend. He is shown to be excited when he gets rainbows on his report card, plus he's obsessed with his own butt. Hit it's epitome in "Kerry to Dance?" when Jake wanted to take Adam to prom (as friends), and got jealous of him taking Kerry instead.
** Unfortunately, for any [[HoYay Ho Yay]] fans, this was explicitly denied in "Up All Night", when Adam nearly kisses Jake and Jake said "Don't get the wrong idea, Adam. I know I'm a looker. And I like you and all, ''(hypermasculine voice)'' but not that way."
* AnimalStereotypes: Oh look, the monkey character is hyperactive and nutty.
* AnnoyingYoungerSibling: Considering he has older siblings, it's likely he's this.
* AntiHero: When he and Adam try to save the day, he's usually the one throwing curve balls at both Adam and himself.
* AntiRoleModel: Obviously not someone the younger viewers should look up to.
* ApesInSpace: Jake's impulsive dream was to become an astronaut in "Pants in Space".
* AttentionDeficitOohShiny: Constantly distracted by trivial things, when Adam's trying to have an important conversation with him.
** This was directly subverted in "Shiny Thing", where Jake was the only student in the school, who wasn't entranced by the glare of the glass doorknob. No in-universe explanation for this was given.
* AttentionWhore: Of his basic cable access show, "Basic Jake", introduced in the episode of the same name.
* AxCrazy: Took this quite literally in "Amazon Kevin", readying himself to break through a door with an ax and possibly pull off a Here's Johnny, terrorizing a poor crocodile hunter.
* BadassMustache: "Nice Mustache"
* BerserkButton: Using the term "going ape" will send him, transcending a downward spiral into unadulterated hysteria.
* BewareTheSillyOnes: Is horrifyingly vicious and violent, when angered.
* BigEater: Orders massive school lunches and engorges on them.
* BishonenLine: His genetic clone in "The Two Jakes", revealed that through [[RapidAging rapid aging]], Jake will develop to look more "human shaped" as he gets older.
* BlowYouAway: Screamed so loud a gust of wind, blew all the students and teacher across the halls in "Inoculation Day".
* BumblingSidekick: Worthless for 98% of every episode, but then redeems himself at the last second ... mostly ... half of the time ... sometimes ... rarely ... I'm not saying "never", cuz he's done it before.
* CartoonyTail: Has a big tail that he swings on trees with and can apparently stretch out very long.
* ChaoticStupid: Only got progressively worse, as the series went on.
* ClassClown: In "Human Behavior", Miss Chameleon told him to make animal calls. He then picked up a phone and said "Hello, animals?", making all the other students laugh.
* CharacterDevelopment: When it comes to this, Jake sort of developed backwards, doing the reverse of what's normally expected from a character of his archetype. In the first few seasons, Jake acted just as silly and reckless as always, but whenever he screwed something up, he's either realize his wrongdoing and try to fix it or get punished for refusing to do so. Overtime, he not only became more stupid and destructive, but he'd also [[KarmaHoudini lack any proper punishment]] and fail to feel any guilt or remorse for what he did.
* TheChosenWannabe: In "Pants in Space", Jake threw a huge fit over not being the monkey chosen to be sent to outer space.
* CluelessDetective: In "Where in the World Are Adam's Parents?"
* ComicallySmallBribe: In "The Notorious Windsor Gorilla", Jake convinced Adam to watch Windsor's commercial, by saying "I'll give you your moisturizer back."
** A very dark subversion happened in "Lonely Lyon", when Jake convinced his friends to help him, by saying "I'll give you your souls back." as he held up a briefcase, supposedly containing the souls of his friends.
* CrazyJealousGuy: A rare male-on-male example whenever Adam hangs out with somebody else.
* DaEditor: Became this in "Poop Scoop", when he worked for the School Newspaper Club.
* {{Deuteragonist}}: He may be the "Monkey" in the show's title, but Adam is the "My", and that word comes first.
* DeusAxMachina: In "Amazon Kevin", he took out an ax and tried chopping open the closet door, to get to his mortal enemy, Amazon Kevin.
* DirtyCoward: Whenever Adam is even remotely involved in one of his destructive antics, he tries placing all the blame on Adam. Sometimes it works, sometimes [[TakingYouWithMe Adam goes down with him]], but there's never a moment, where Adam doesn't get in trouble.
* DisproportionateRetribution: When Adam used the term "ape" in "The "A" Word", Jake was so offended that he unfriended Adam and looked for a new one. Adam tortured himself, trying to make it up to him, only to find out [[spoiler:"ape" was a compliment and he was jealous Adam used it on someone else.]]
* DistractedByMyOwnSexy: In this case, all the sexy is focused entirely on his butt.
* TheDitz: The guy's a moron.
* DumbJock: Although not to the extreme that's usually expected in media, in "Lyon of Srimmage", it was made clear the guy had a great football throwing arm, but was terrible at understanding the rules ans strategies.
* DumbassHasAPoint: In "Pride and Pixiefrog", he surprised even himself, when he abruptly made logical predictions on what future events would unfold, using information from the current situation.
--> '''Jake:''' If I made sense, it was totally on accident.
* EquippableAlly: From time to time, Adam has thrown him or grabbed him by the tail, using him as a medieval flail.
* EverythingsBetterWithMonkeys: The show wouldn't be the same without him. I mean, come on, who would Adam's gym partner be then? Lupe?
-->'''Adam:''' My Gym Partner is a Toucan.
-->'''Lupe:''' Toucan! Toucan! Toucan!
-->'''Adam:''' Bullshark, porcupine, I don't know what. Going to this school's a pain in the-
-->''(Lupe grabs Adam in mid-air)''
-->'''Lupe:''' Oye! Adam, leave the distasteful remarks to me, comprende?
* ExposedAnimalBellybutton: Shown when he unzipped his fur in "Chew on This".
* ExtremeOmnivore: Ever since his discovery in "Chew on This", Jake hasn't been afraid to try new things, whether these "things" are edible or not. In one episode, he and other animal students started eating books, which helped them absorb knowledge better than reading them.
* {{Expy}}: Jake can often be reminiscent of [[WesternAnimation/SpongebobSquarepants Spongebob]], both having the same [[Creator/TomKenny VA]] and being annoying, pint-sized, dimwits, who cause chaos and mayhem and don't get in trouble for it. At times when Jake screams really loud, it's easy to picture Spongebob making the same noise, himself.

* HehHehYouSaidX: Does this whenever someone says anything even slightly butt-related.

* HiddenDepths: In "The Citronella Solution", he had the ability to levitate, using only his mind, and in "Lie, Cheetah, Steal", he solved complex math equations in his head, during his free time.

-->'''Jake:''' You should know by now, I can't be trusted with anything I say ... ever.

* MisspellingOutLoud: "D E R F"
* MysteriousMiddleInitial: It's never learned what "P" stands for.
* NWordPrivileges: Subverted in "The "A" Word", where Jake was heartbroken by Adam's use of the word "Ape". Apparently, this was the equivalent of "The N Word" in the monkey community and Adam went through Hell, digging himself out of the hole he put himself in. In the end, it turned out [[spoiler:"Ape" was actually the greatest compliment in the monkey community and Jake was jealous Adam used it on someone other than him.]]
* NakedPeopleAreFunny: Thinks jokes about his own butt are downright hilarious.
* NeverMyFault: Never takes responsibility for his actions. Ever. Most of the time, the blame is placed on Adam.
* NiceHat: Got a cool, blue baseball cap.
* NoodleIncident: In "Glazed and Confused", Adam mentioned him being involved in some kind of accident at a bubblegum factory, which caused him to lose all his fur. Now he has to wear a toupee.

* StrongFamilyResemblance: His parents are just slightly bigger versions of him with maternal-and-paternal-specific [[TertiarySexualCharacteristics tertiary sexual characteristics]].
* StupidityInducingAttack: This would be him going full on ape and acting like a psychotic, killing, monkey. His stupidity keeps him from understanding how much damage he's really causing, making even more relentless.
* TooDumbToLive: In "Guano in 60 Seconds", Jake nearly killed himself, and the entire school, by setting a trailer, rolling down a dangerous highway, while everyone was in it, and destroying the breaks.

[[folder:Slips Python]]
->Voiced by: Rick Gomez

An easy-going, street-talking green tree python. He is an underachiever and excessive daydreamer who's gullibility allows him to believe anything he hears, which makes him a constant source of misinformation.
* SeventiesHair: He's got a blond wavy gravy hairdo, which goes great with his hippie-like personality.
* AgentMulder: Slips' gullibility allows him to believe everything he hears, making him a consistent source of misinformation. Windsor often plays the [[AgentScully agent scully]] to this side of him.
* AmazinglyEmbarrassingParents: Slips is so embarrassed by his totally lame parents in public, man.
* AnimalJingoism: Parodied in "Mongoosed", a mongoose, his natural enemy, as a snake, were the best of friends, before realizing that they're supposed to be enemies for some reason, causing them to automatically hate each other, without any actual reason.
* AudienceWhatAudience: Slips might be the only character, who doesn't comprehend the fact that he's in a cartoon.
* BewareTheSillyOnes: Despite being a ditzy and a self-admitted "loser flunkie", he's the only member of the group who is an actual carnivore, and can be rather dangerous when he becomes hungry.
* BookDumb: Doesn't even know what books are, but sure can [[{{Pun}} slither]] his way out of a street situation.

* DissonantSerenity: Often super chill in the chaotic moments of CDMS.
* TheDitz: Moreso the anyone else in the show. He is very gullible.

* DumbIsGood: Seems to be the most laid-back and care-free member of the pack, due to his stupidity and lack of knowledge about anything going on around him.
* DumbJock: Slips is no brain surgeon, and he was on the football team in "Lyon of Scrimmage".
* DumbassHasAPoint: Slips is actually a distinguished, highly sophisticated young man, whose intelligence is being repressed by Jake and his peer pressuring behavior, as seen in "The Ivy League".
-->'''Slips:''' I realized after Jake left, that his constant barrage of buttock buffoonery was dumbing everything down. I feel so much clearer and smarter now.
* EnlightenmentSuperpowers: In "Mellow Fellows", he had a deep understanding of human and animal emotions and was able to effortlessly solve people's most internalized of mental and psychological distress in seconds.
* EquippableAlly: Can be used as a sword or a bat by Windsor.
* ExtremeOmnivore: Ate a painting in "The Notorious Windsor Gorilla".
* TheFool: Although, he often has to compete with Jake, for that title.
* FourTemperamentEnsemble: Phlegmatic.
* HandicappedBadass: Being a snake, he is violent, when going into attack mode, regardless of him being the animal equivalent of a quadruple amputee.
* TheHeart: He's the member of the pack with feelings.
* HiddenDepths: In "The Ivy League", he proved to be an extremely intelligent, well-spoken, scholarly individual, who only acted stupid, due to Jake, repressing his true knowledge. Not to mention, this side of him wasn't complete, without him wearing [[SmartPeopleWearGlasses giant smart guy glasses]]. Add to that, since he was a snake, and therefore had no ears, his glasses had to be [[MakingASpectacleOfYourself supported with tape]].
* IHaveNoSon: Though it's never seen on screen, Slips heavily implies in dialogue, that his father disapproves of him being such a failure. Fortunately, he seems to [[IgnoranceIsBliss delightfully dim-witted to notice]].
* IgnoranceIsBliss: His strategy for getting through the madness of CDMS.
* InvisibleAnatomy: Though it's rarely ever shown, Slips will prove the ability to manipulate his sleeves, despite having no arms.

* NonMammalianHair: His blonde hair.
* NoticingTheFourthWall: Didn't know he was in a cartoon until Windsor explained it in "Human Behavior".
* OutOfFocus: Slips had no dialogue in the first episode.
* PainfulTransformation: His first time shedding his skin in "The Sheds".
* PredatorsAreMean: Mostly subverted, but starve him for too long, and he'll start to go crazy and try to eat his own friends. An example is from "A Very Special Boy", when he [[MeatOVision envisioned Adam as a turkey leg]], and tried to devour him alive.
-->'''Slips:''' At this point, not even the cargo shorts are keeping me from wanting to eat you.
* ReptilesAreAbhorrent: Averted. He's actually a pretty decent guy.
* ScaryTeeth: Shows his predatory fangs, when he's angry.
* SeldomSeenSpecies: A green tree python.
* ShownTheirWork: Pythons are slow-moving, nearly silent animals that can often be found hanging from tree branches and sunning themselves, especially after a particularly big meal. Imagining one as a laid-back slacker is not much of a stretch.
* SignatureLaugh: He has a hissing laugh.
* TheSlacker: Louses around in class and gets no work done.
* SnakesAreSinister: Subverted. Slips doesn't have a mean bone in his body.
* SoProudOfYou: In "The Ivy League", Slips mentioned finally gaining his father's approval, [[NoodleIncident though it's never explained what he did]].
-->'''Slips:''' [[AndThenISaid Then father said]], "Way to go, son. I'm finally proud of you."
* SorryBillyButYouJustDontHaveLegs: It never fails to disappoint Slips or hinder his dreams, knowing he has no significant limbs.

* {{Sssssnaketalk}}: Surprisingly, not often with him. It does happen, though, whenever he goes primal and lets out his inner-viciousness, turning into the true, constrictor snake he is.
* StrongFamilyResemblance: His parents are larger versions of him with [[TertiarySexualCharacteristics tertiary sexual characteristics]] and different shades of green. Same goes for his "sister", who's basically a beefier, muscular version of him.
* SurferDude: Talks like this.
* TheStoner: Acts like one and if this show wasn't for kids, he'd often be seen laying back in a beanbag chair, coiled around a bottle of bong, pondering the nature of the universe, but coming up with ridiculous theories as to why we're all here.
* TokenEvilTeammate: Slips is a meat-eating serpent, who has no trouble devouring live animals, such as gerbils and rats, making him the one predator in a herd full of prey. Though in his case, "evil" is a very loose term.
* VerbalTic: Dude, he says "Dude" at the beginning, middle, dude, and end of a lot of his sentences, dude.
* WhyDidItHaveToBeSnakes: Despite being one, even ''he'' can't stand them.
* YourSizeMayVary: The length of Slips' body is sometimes extended, mostly on purpose, to make it more suitable for a certain scene or gag, which requires him to be that long.

[[folder:Windsor T. Gorilla]]
->Voiced by: Rick Gomez

A highly intelligent lowland gorilla who serves as the anti-bully at the school and often gives confusing wisdom to people. He speaks in a soft-spoken and nearly monotonous manner, often stringing together technical words as a matter of his normal speech.
* AbsurdPhobia: Apparently has a fear of small animals that are generally seen as adorable and otherwise harmless. In "Mellow Fellows", he mentioned having a fear of kittens, and in "Four Eyed Jake", he was shown to have a fear of puppies.
* AcquiredSituationalNarcissism: In "The Notorious Windsor Gorilla", he goes through the whole shebang. He becomes famous for something someone else did, [[{{Pride}} let's it go to his head]], [[SpoiledBrat throws a diva tantrum]], [[PopularityPolynomial and knocks himself down to yesterday's news]], all over the course of [[FifteenMinutesOfFame 15 Minutes]].
* {{Adorkable}}: Windsor's a nerdy science/math/history geek, alright and he's had his cute moments. Though we don't see it much, his adorableness comes out, when he's at his most vulnerable. Like when he's shy around his girl crush in "Gorilla My Dreams" or if he's emotionally distraught in "Mandrill of the House".
* AffectionateNickname: Was called "Gorilla Boy", by his girlfriend, Deborah Ape.
* AgentScully: Often in contrast to Slips' [[AgentMulder agent mulder]], Windsor always has a rational explanation for everything, with the exception of "That Darn Platypus", when he was totally on board with him on the idea of aliens invading the school.
* AlwaysSomeoneBetter: He was the better man in "Pants in Space". When CDMS planned on sending a monkey student to space, Jake was totally on board with it and he would've been sent straight on there, no questions asked, if not for the introduction of much more audible candidate, the illustrious Windsor Gorilla. After all, he is the smart one, who's fascinated with space, and he's not a destructive idiot like Jake, so can you really blame him?
* AmbiguouslyBi: In The Hyena And The Mighty, he calls Rufus Hyena his sweet, implying the two may be in a relationship despite Rufus being a one shot character. However, later, he was seen being attracted to another female gorilla.
* ApesInSpace: Windsor suddenly had dreams of becoming an astronaut in "Pants in Space".
* ArtEvolution: Very subtle, but in the first episode, Windsor's eyebrows are very thick, saturated, and bushy, but this all goes away as early as Episode #2.
* BadImpressionists: His "voice impressions" of people are just him using his normal voice, and saying phrases they'd usually say.
* BerserkButton: Mentioning his mother's romantic life, will, in seconds, make him snap and go completely [[HulkingOut ape]].
* BigEgoHiddenDepths: "Mandrill of the House" proved that Windsor has a heart as big as his brain, and he gave a large part of it toward hid mother.
* TheBigGuy: A large gorilla.
* BigGuyLittleGuy: He's the big guy to best friend, Slips' little guy.
* BlackFace: Lampshaded in "Flesh Fur Fantasy", when Windsor got offended by Adam dressing as a gorilla.
* TheBore: His long-winded spiels about scientific facts tend to drone on and bore people witless and he knows it. He mentioned in "A Very Special Boy", that he does this intentionally, to keep people he doesn't like from talking to him.
* BrainsAndBrawn: Both.
* BrainyBrunette: He is considered "brainy" and his hair does in fact have brown pigments. Fits like a glove.
* TheCaretaker: Served as this to Rufus Hyena, when he was crying, and in need of help.
* CheshireCatGrin: Given the largeness of his mouth, he looks like this on the rare moments, when he smiles. Guess that's why he mostly talks out of the side of his mouth.
* CharacterDevelopment: In the first few seasons, Windsor was an emotionless slate, with no internal desires or emotions other than apathy and condescension, but in episodes like "Mandrill of the House", "Gorilla My Dreams", and "Flesh Fur Fantasy", he's proven to have a beating heart under all that fur, and a few things that [[BerserkButton trigger]] him, such as his mother, cultural appropriation, romantic desire, etc.
* ChildProdigy: Windsor's given age is either 11 or 12 years old, seeing as how he's in the same grade as Adam, this being 6th grade. Yet, he's far more intelligent than everyone else at his learning lever and even exhibits more knowledge than his teachers on various school subjects. Not to mention his deep interest in the universe and his absurdly advanced vocabulary.
* CloudcuckoolandersMinder: To Slips.
* ComicallySerious: Sometimes, he can be at his funniest, when he's just explaining something logically.
* TheConscience: Most notably to Slips, but can even be this to usual voice of reason, Adam. Like how no one listens to Adam, Windsor gets the same reaction from him.
* ConsultingMrPuppet: Sees Teddy Truman, a ventriloquist dummy of his as a different person, who he has emotional problems with.
* CursedWithAwesome: Windsor's self-proclaimed "good looks", or lack thereof, have gotten him in lots of trouble. In "Gorilla My Dreams", he became the love interest of a very unattractive girl. In "The Notorious Windsor Gorilla", his photogenic appearance put him through an [[AcquiredSituationalNarcissism acquired situational narcissism]] story. Maybe it's best to consider these self-proclaimed good looks are more "self-proclaimed" than they seem.
** He probably [[StrongFamilyResemblance gets it from his mother]], given how much of a [[ChickMagnet dude magnet]] she is.
* DaddyIssues: Windsor's dad doesn't live with him and is divorced from his mom, and has overall, never physically appeared, but he's been mentioned a few times before and Windsor has some major [[IAmNotMyFather I am not my father]] problems with him, that really hit close to home, when he's reminded of them.
* DeadpanSnarker: Prone to sarcasm.
* DitzyGenius: Despite being the smart one, he was paranoid about an alien invasion in "That Darn Platypus", he acted like a buffoon in front of his [[LoveInterest school crush]] in "Gorilla My Dreams", and had trouble distinguishing robots from teachers in "Robo Frog 3000".
* EncyclopaedicKnowledge: Delivers college essay-worthy descriptions on many different subjects, every time he's asked about them.
* {{Fanboy}}: Of Jimminy Japoopy.
* FatAndSkinny: He and Slips.
* FlatJoy: Does nothing but flatly say the word "Joy", when happy.
* {{Foil}}: Windsor shows off Slips' stupidity with his intellectual contrast.
* ForScience!: That's Windsor alright.
* FourTemperamentEnsemble: Phlegmatic.
* FourthWallObserver: Although Adam and Jake break the fourth wall the most, Windsor's the most "Meta" with his breakages.
-->'''Windsor:''' Adam, for the past two seasons I've had you pegged as a classic narcissist. Obsessed with his own feelings of not fitting in around here. But, by offering to be my coach, I now see that you understand how to make a sacrifice for the common good.
* TheFinickyOne: Can be rather uptight and neat freakish sometimes.
* FragileFlower: Emotionally, at least. He still is very much a tough as nails, buff guy.
* FreudianSlip: When Mr. Mandrill started dating his mother, this was a constant dilemma with him.
-->'''Windsor:''' Hey, why don't you roll around in someone else's mudder, uh ... I mean mud.
* FullyDressedCartoonAnimal: Only main character to wear an entire outfit.
* GeekPhysiques: Subverted, has more of a "Jock Physique" than anything.
* GeniusBruiser: He's both intelligent and powerful.
* GentleGiant: Despite his massive physique, he's perfectly capable of taking care of a baby for a school project.
* GentlemanAndAScholar: Windsor may appear as sarcastic and condescending, but that's because we mostly see him, hanging around a bunch of dimwits and buffoons. If you see him interacting with people of genuine or at least average intelligence and only people of said intelligence, (i.e. Adam Lyon in "Pants in Space"), he's a very respectful, friendly man.
* GirlOfMyDreams: Played straight with Deborah Ape, and [[JustForPun punned]] in the title of the episode in question, "Gorilla My Dreams".
* HolierThanThou: In "Pants in Space", he was the [[AlwaysSomeoneBetter better candidate]] for being an astronaut than Jake.
* HulkingOut: Windsor occasionally goes full-blown primitive gorilla.
* IAmNotMyFather: Windsor hinted at having a real issue with this in a one off joke in "Ain't Too Proud To Egg", where he yells at his [[EggSitting egg son]], and then realizes he's directly quoting his [[DisappearedDad father]].
* ILied: At the end of "The Hyena and The Mighty", [[spoiler:he revealed to have lied about Rufus Hyena's impending demise, earlier in the episode.]]
* LovableNerd: Very.
* MobileShrubbery: Used a moving bush to hide from Deb, but all the leaves fell off, when she spotted him.
* MommasBoy: To Margie.
* MonkeysOnATypeWriter: In "Shiny Thing", he wrote his school report, by pounding on a typewriter.
* MysteriousMiddleInitial: It's never learned what "T" stands for.
* NeatFreak: Though not much, he's shown a few symptoms of this.
* NiceHat: A green beanie that's always at a protruding angle.
* NonMaliciousMonster: A non-threatening gorilla.
* NotSoAboveItAll: Tries to act like in-series media, such as Yo Mama, Jimminy Japoopy, and The Rhinossance Fair, are beneath him, since they're too "stupid" and don't "challenge his intelligence" enough, but there's no denying he's just a big a fan of that stuff as all the dumb people.
* OedipusComplex: Has a few issues with his mother, dating non-his-father people, as seen in "Mandrill of the House", [[spoiler:and a one-off joke at the end of "The Notorious Windsor Gorilla]].
* OutOfCharacterMoment: He revealed that he has a stupid sounding voice with a tongue-sticking-out, spit lithp, and that his intelligent vocal pattern is false, and used to protect an aura of deep intelligence.
* ParentWithNewParamour: Windsor played the "disapproving kid" role, when Mr. Mandrill started dating his single mother.
* PerpetualFrowner: Always has the same, dull, emotionless, stoic expression of dead eyes and a big fat frown, and although he does, rarely even changes it, when happy, scared, angry, etc.
* PrimalChestPound: He IS a gorilla, after all. In one episode, he uses this to call his friends. Curiously, while most episodes has him do it with clenched fists like most cartoon gorillas, in "The Notorious Windsor Gorilla" he pounds his chest with open hands like a real gorilla would.
* SeriousBusiness: Schoolwork, and he's probably the only one of the group, who takes his work seriously.
* SesquipedalianLoquaciousness: Windsor tends to make his sentences as overly eloquent as possible, by throwing in as much big smart words as could possibly substitute shorter ones.
* ShirtlessScene: In "Don't Noc It 'Til You Try It", Windsor tore off his shirt and pounded his chest to summon the others.
* ShownTheirWork: Gorillas are known to be large, intelligent and generally mild-mannered. Windsor's status as a [[TheStoic stoic]] GeniusBruiser fits perfectly in this regard.
* SignatureLaugh: "Laughter."
* SitcomArchNemesis: Teddy Truman, and his [[TheComicallySerious comically serious]] personality makes it all the more funny.
* TheSpock: That's Windsor, alright.
* StraightMan: To Slips' comic.
* TookALevelInBadass: In "Mandrill of the House", Windsor became more prone to protective violence and defensive rampaging, being able to destroy everything in sight and kick the sorry asses of anyone who dares mock him. This sudden surge of badassery was fueled by his mother dating his health teacher, and the awkwardness and pain this brought upon him.
* {{Ventriloquism}}: Windsor's recurring ventriloquist dummy, Teddy Truman.
* WhamEpisode: His would be "Mandrill of the House", where he went through some extreme [[CharacterDevelopment character development]] and revealed tons of [[HiddenDepths hidden depths]] about his life at home, life his parents, his true emotions, etc. Truly, this was the moment when Windsor stooped being the generic "smart guy" archetype, he usually acts like and starts becoming someone spectacular.
** Another "sort-of-whammish" episode would be "Gorilla My Dreams", where Windsor also shows emotions, reveals his soft side, has his first crush, and learns some stuff that makes him believe stuff he didn't believe when the episode started.
* WiseBeyondTheirYears: Despite being 12, Windsor knows more than the teachers.
* YouAreTheNewTrend: In "The Notorious Windsor Gorilla", just because of a big-eyed painting of his face.

[[folder:Guadalupe "Lupe" Toucan]]
->Voiced by: Creator/GreyDeLisle

A female Keel-billed toucan, who is loud-mouthed, acerbic, dominating and materialistic, although she considers herself to be mild-tempered and low maintenance.
* AbsurdPhobia: Has a fear of French Toast.
* ActivistFundamentalistAntics: In "Diplomatic Insanity", Lupe physically abused Adam and threatened to sue the school, all because she thought the teachers and students were enforcing negative toucan stereotypes.
* AttentionWhore: Sometimes wears bright, flashy clothes and needs everyone to pay attention to her.
* BadassAdorable: She may be tiny and cute, but she's probably the most violent and quick to anger member of the pack.

* BewareTheNiceOnes: A loyal and friendly companion, but piss her off and she'll return the favor, only she'll make it [[DisproportionateRetribution 1000 times more painful]].
** In "Diplomatic Insanity", she was sick of people making jokes about Kiki Von Beaky. She threatened anyone who would dare mock her again. Adam and Jake did just this, not hearing about what she said, and Lupe came down and apparently nuked them, but only gave Adam an [[AmusingInjury amusing injury]].
** In "She's Koala That", Deidre insulted her, after she helped her become popular. Lupe darted after her like a bullet, ready to give her the beating of a lifetime.
** In "Lupe in Love", she did the biggest of them all, [[spoiler:when Orlando "dumped" her]].
* BigGuyLittleGuy: The little guy to Ingrid's big guy.

* CatchPhrase: Usually putting "Oye!" at the beginning of angry sentences.
* TheCheerleader: As seen in "Cheer Pressure".

* FantasticRacism: In "Diplomatic Insanity", she was mad about toucans being mocked and underrepresented in TV and media and caused a school-wide protest about special equality among all animals.
* TheFashionista: Lupe is obsessed with her appearance, especially when it comes to clothing and jewelry.
** Ironically, she's the only member of the herd, who [[HalfDressedCartoonAnimal never wears any clothes]].
* {{Flight}}: Being a bird, this can be considered her special "superpower" on the team.
* FourTemperamentEnsemble: Choleric.
* TheFriendNobodyLikes: She's occasionally, but but too often, shunned by the herd for being egotistical, loud, and annoying.
* FunnyForeigner: She'd probably be nothing more than the [[TokenMinority token Hispanic friend]] if cast was all humans.
* GagNose: Or in this case, a beak.
* GenkiGirl: Loud, exuberant, crazy at times.
* GratuitousSpanish: Lupe always throws in a Spanish word, that sounds similar enough to it's English counterpart to be understood, in the middle of her sentences.
* HatesBeingTouched: Lupe once tried to bite Adam's head off for yanking her feathers off, but couldn't because of some "protected status" garbage.
--> '''Lupe:''' NO! YOU CAN NOT DO THAT! ''(Lupe roars and attempts to attack Adam, but then abruptly silences herself)'' Actually, yes. Yes, you can. ''(sticks out another tail feather)'' You missed one.
* HenpeckedHusband: This is how she treats her boyfriend, Corey.
** She probably looks for this in a man. Since in "Ain't too Proud to Egg", she tried wearing the pants in her [[EggSitting egg assignment]] relationship with Slips, but he was just too confident.
* HiddenDepths: In "A Very Special Boy", she revealed to have a very, clear, normal-sounding voice, that came with a fluent American accent, but she just pretends to have an obnoxious, raspy Spanish accent to ward off predators.
* HumanHummingbird: In later seasons, this was her standard wing position, while in flight.
* InterspeciesRomance: We're reaching a bit with this, but she, a toucan is dating, Corey, a vulture.
* JerkWithAHeartOfGold: Lupe has a good heart despite how annoying she is.

* ManipulativeBastard: Lupe wears the pants in both her friendship with Ingrid and relationship with Corey and she knows it.
* MotorMouth: Often runs her beak, in conversations with Ingrid or Corey.

* SecretIdentityVocalShift: In "A Very Special Boy", she reveals that her real voice is perfectly normal and she speaks fluent English. She just disguises it with a loud, raspy, Spanish accent, to ward off predators.
-->'''Lupe:''' I-I lift my voice several octaves and put on an-an outrageous accent. Sometimes I yell. Most predators don't wanna devour an noisy meal, so they just move onto someone else.

* VitriolicBestBuds: With Ingrid.

[[folder:Ingrid Giraffe]]
->Voiced by: Creator/GreyDeLisle

A female masai giraffe. Her towering height only adds to her feelings of insecurity as she tries desperately to blend into the background. She has a crush on Adam.
* {{Adorkable}}: Shows shades of dorky behavior. She's gawky, gangly and sweet.
* AesopAmnesia: In "Kerry to Dance?", she learned to stop hating Kerry for being Adam's love interest, but in "A Thanksgiving Carol", she was shown to be jealous of her again.
* AllGirlsWantBadBoys: In "Ingrid Trough the Out Door", Ingrid admitted to disliking Adam's being a pansy. When she heard about a so-called high school older brother of his, she was instantly into dating a guy with a bit more social strength.
* AllLovingHero: Ingrid is kind to all living things, even if they don't return her favors.
* AlphabeticalThemeNaming: Her sister's named "Inga".

-->'''Windsor:''' If I'd have known it'd end so soon, I'd have eaten more butter.
-->'''Ingrid:''' I'd have apologized more for things I didn't do.
-->'''Slips:''' And I'd have eaten more butter.
-->'''Windsor:''' Hey! You stole mine!
-->'''Ingrid:''' I'm sorry!

* BigGuyLittleGuy: (or gal in this case), Ingrid's the big gal to Lupe's little gal.
* BreakTheCutie: Quite a few episodes do this to her.
* TheChick: Among the pack, She and Lupe intervene with this role. Basically, whenever Lupe becomes [[TheLancer the muscle]], the [[MotorMouth chatterbox]], or the [[SpicyLatina spicy Latina]] of the herd, or takes on any other trait that's not [[AlwaysFemale specifically feminine]], Ingrid becomes the chick.
* CatchPhrase: "I'm sorry!"

* ClingyJealousGirl: In "Lyon's Anatomy", despite how she wasn't dating Adam.

* CuteClumsyGirl: Tends to trip frequently.
* ClingyJealousGirl: She tries to break up Kerry and Adam more than once.

* {{Diary}}: Cover to cover, she has one full of cute things that Adam has done. Principal Pixiefrog bought and read it in one episode, enjoying all the juicy details, which of course, humiliated her.
* DrivenByEnvy: Her primary motives in episodes focusing on her. 90% of the time, it's about another girl swooping in on her Adam.
* DynamicCharacter: Although her favorite thing in the whole wide world of Adam Lyon, later seasons show that she has quite a few secondary interests, such as Acacia trees (but that was kind of a major trait from the beginning), hairclips, Asian culture, and tulips.
* EncyclopaedicKnowledge: Knows everything about her own species, even how much hours of sleep they need per night.
** [[CharacterizationMarchesOn However]], she (A.K.A. the dialogue writers) [[CriticalResearchFailure don't know what "ossicones" are]], as in the episode "Save the Drama for Your Llama", she referred to Lola's false ossicones as "antennas".
* EveryoneHasStandards: Although she's madly in love with Adam, she was repulsed by him being bald and naked in "The Cuddlemuffins", and refused to hug him, unless he paid her.
* FashionHurts: In "Kerry to Dance?" she wore high heels, which caused her to trip, and burned her corneas with glitter, when applying too much makeup.
* FlowersOfRomance: Her favorite flowers, tulips are a sign of romance.
* ForcefulKiss: After being denied in "Hygiene Hijinks" she pulls this on Adam often in the musical episode.
* ForeignCultureFetish: Has a bit of an obsession for Asian culture.
* FourTemperamentEnsemble: Melancholic.

* GentleGiant: The tallest kid in the school, and is very kind and mild-mannered.
* GirlyGirl: Every now and then. Taken to extremes during her musical number from "Animal School Musical".

* HarassingPhoneCall: Her infatuation for Adam had intensified by the events of "Animal School Musical" where she is ''constantly'' calling him, even when he's not home.

* HotSkittyOnWailordAction: The outcome of Ingrid's hypothetical relationship with Adam.
* HugeSchoolgirl: The tallest student in the school (her head is out of the screen most of the time).
* TheHunterBecomesTheHunted: She was on the "hunted" side of the spectrum, when she was one of the few prey animals to join Marlin Perkins Wild High School.
* InterspeciesRomance: Her crush on human boy, Adam Lyon.
* JoinsToFitIn: In "Ingrid Through the Out Door", she befriended some fellow tall people at a high-school, after being the "tall one" in the pack was ticking her off.
* LongNeck: Perfect example.
* MinorMajorCharacter: Despite being a main cast member, she'll often get left out of the group entirely, if left with little to no dialogue. This was [[LampshadeHanging lampshaded]] in the musical episode, during her [[MomentOfAwesome moment of awesome]].
--> '''Ingrid:''' Listen! I've barely had three lines in this musical! Maybe you think giraffes are supposed to be some kind of mute creatures, BUT WE ACTUALLY HAVE BEAUTIFUL SINGING VOICES!!!
* MundaneObjectAmazement: Fuchsia Acacia leaves.
* MyFriendsAndZoidberg: The outcast of the pack.
* NiceGirl: One reason why she's so submissive and overpowered is because she's the most polite and mild-mannered member of the herd.
* TheOnlyOneITrust: Can only trust people within her friend circle, as everyone else will take abuse, take advantage of, and leave her.
* OurGiantsAreBigger: Her older sister is twice her size.
* OutOfFocus: When it comes to merchandise, there are no toys of her. Although, this is most likely due to the fact that her exaggerated size makes it rather tricky to put into toy-form, without making an oversized product or derailing her from her actual appearance.
* PowerUpFullColorChange: When her [[BerserkButton berserk button]] is hit, and she finally takes charge of things, her body goes from it's natural yellow, to becoming bright red, with anger.
* ShrinkingViolet: A shy giraffe.

* SmittenTeenageGirl: Has a typical schoolgirl crush on Adam.
* StalkerWithACrush: To Adam of all people.
* TinyGuyHugeGirl: She, and Adam to a massive extent.
* WithFriendsLikeThese: In "Sidekicked" it was hinted, she secretly yearned to knock some sense into Lupe to stop that beak of hers from squawking anymore.
* {{Yandere}}: She can get pretty crazy about her crush on Adam.
* YourSizeMayVary: Ingrid's height is completely inconsistent in pretty much every frame she's in. The animators made a stylistic choice of never showing her entire neck all at once, and with these intended height contradictions, to break this rule would be pretty pointless, since episodes such as "Ingrid Through the Out Door" have jokes that her neck is long enough to knock satellites out of orbit.

!!Other Students
[[folder:Virgil "Bull" Sharkowski]]
->Voiced by: Creator/PhilLaMarr

A bull shark and the school's bully.
* AlwaysSomeoneBetter: His older sister is a way better bully than he'll ever be. He's extremely sensitive about this fact. Especially so when she managed to teach Adam to go frenzy in minutes though trolling. A concept he himself spent the whole episode trying to teach the ever oblivious Adam to no avail.
* AscendedExtra: In "[[MusicalEpisode Animal School Musical]]", he was treated like the [[SixthRanger seventh]] member of the pack, being on the same importance level as Adam, Jake, Slips, Windsor, Lupe, and Ingrid. Apparently, Bull plated the "[[TheBigGuy The Muscle]]" of the herd. This, however, only lasted for the first two songs of the musical, before he was cast back into the shadows again.
* BarbaricBully: Bull Sharkowski is a very primitive bully, whose methods of bullying are more heavily based on his [[AnimalJingoism shark roots]], than they are on classic [[TheBully school bully archetype]] forms of bullying, like wedgies, wet willies, etc. Bull viciously rips smaller kids apart and eats them like prey, tears apart school property that gets in his way, does things that would kill someone in real life, and is overall, just plain uncivil.
* BigLittleBrother: His older sister is much smaller he is.
* BruiserWithASoftCenter: It's been expressed on more than enough occasions, that Bull is a real softie deep down. Most notable moments are when Euripides proves her dominance over him, making him burst into tears. In later seasons, he was consistently more cowardly, emotional, and "pansy like", due to {{Flanderization}}.
* BracesOfOrthodonticOverkill: He actually hates his braces, since they only make his [[ScaryTeeth evil smile]] all the more ugly. Yes, apparently Bull, doesn't like his "threatening and scary look". The fact that he acts the way he looks is just him going along with his appearance that can't change.
* TheBully: The most notoriously feared bully at CDMS.
* BullyAndWimpPairing: With Henry.
* CainAndAbel: The Abel to Euripides' Cain.
* {{Catchphrase}}: "You're dead, Lyon!" (from time to time, it's replaced with someone else's name)

* EvenBadMenLoveTheirMamas: He was the dedicated #1 Grandson of his grandmother in "Bullroar".

* GangOfBullies: Often accompanied by his two {{Mooks}}, Brandon Capybara and Harry Bat.

* JerkJock: Bull's a Mad Cow and a bully. His story checks out.
* {{Jerkass}}: Everyone in the school hates and fears him.
* KickTheDog: When Bull gets pissed off, he often adds a bit more unnecessary cruelty to his outbursts, like beating up a small kid or breaking someone's important belongings, just for dramatic effect.
* {{Megalodon}}: That's Bull, alright.
* MobileFishbowl: Wears a special headset over his gills to breathe while on dry land.
* MoreTeethThanTheOsmondFamily: As a shark, he has approximately 50 teeth, spanning 3 or more rows. [[spoiler:As soon as his braces, straightened them out, another row grew in, being just as hideous as the last.]]
* ObviouslyEvil: Due to him being a [[ThreateningShark giant snark]], with [[ScaryTeeth sharp fangs]] that are visible, even when his mouth is closed, a [[PerpetualFrowner static expression]] [[AngryEyebrows with angry eyebrows]], and a threatening T-shirt, it's impossible for him not to be a villain of some kind.
* OneManArmy: Can clear out a hallway, using only his fins and fangs.
* OnlyKnownByTheirNickname: He's mostly called "Bull"
* PresidentEvil: "Political Animals".
* ScaryTeeth: Bull is disgusted by his own sharp and crooked teeth.
* SeldomSeenSpecies: A bull shark.
* ShownTheirWork: Bull sharks are known to be a highly aggressive shark species and more dangerous to humans than even great whites, due to high levels of testosterone in their bodies. It's no wonder why they chose one to play the school bully.
* ThreateningShark: Obviously.
* VerbalTic: Takes a deep breath between his words every once in a while.
* WouldHitAGirl: Has no problem with inflicting physical violence on Ingrid, Lupe, or other female students at CDMS.

* {{Backstory}}: Had a [[SarcasmMode VERY riveting and intriguing]] backstory of how his family ended up in Greenland, where he grew up.

* BlindWithoutEm: Can't see without his glasses.
* ButtMonkey: If there's anyone at the school, who gets crapped on more than Adam, it's Henry. Unlike Adam, however, he still manages to keep a [[ThrowTheDogABone bright and sunny attitude]] no matter what happens to him.
* {{Chatterbox}}: Drives people nuts with his constant ramblings about his life. That's why nobody ever talks to him.
* CheerfulChild: Even though he's probably the most mistreated, unfortunate soul at Charles Darwin Middle School.
* DependingOnTheWriter: Though usually a [[TheWoobie woobie]], he was portrayed as a {{Jerkass}} in "Making the Grade" and "The Big Field Trip".
* DrunkWithPower: Completely changed into a [[BigBad mega villain]], when given respect and social popularity in "Making the Grade".
* EnemyMine: Everyone else in the school turned against each other in "Oh, Henry!", when trying to make Henry happy, [[spoiler:but when Henry said he liked the negative attention they gave him before]], they stopped fighting and then focused all their anger on beating the living crap out of him.
* EvenNerdsHaveStandards: Will do anything to humiliate himself, except for [[DirectionlessDriver ask for directions]], as it would "demean his animalhood".
* FourTemperamentEnsemble: Sanguine.
* GoodFeelsGood: Despite the physical pain it puts him through, Henry feels very happy and at peace, with doing good for others.
* HarmlessVillain: In "Making the Grade", he turned to the dark side and caused no harm.
* HopelessAuditionees: In "Me Adam, You Jake", he was a miserably unqualified auditioner for the lead role in the school play.

-->'''Miss Chameleon:''' Jungle Guy.
-->'''Henry:''' Jungle Guy. You, ... line?
-->'''Miss Chameleon:''' Next!
-->'''Henry:''' Next! ... Line?

* IntrepidReporter: He works for the CDMS news channel. In "Law and Odor", he stopped at nothing to get all the dirt on the corruption in the hall monitor union.

* NerdGlasses: Wouldn't be complete without them.
* NerdyInhaler: Needs an inhaler.
* NiceGuy: He's a kind, loving creature to everyone. And that's the reason, he's the school's biggest target for bullying and abuse.
* OutOfCharacterMoment: Became a brutal, elitist, discriminating bully in "Making the Grade".
* PlayingPossum: A brief shot in "Animal School Musical", featured Henry laying down on the street, while a truck approached him.
* PutMeInCoach: In "Lyon of Scrimmage", he was benched until the final play of the last game, [[spoiler:which of course, helped win the game]].
* SmallAnnoyingCreature: He can really be obnoxious to some people.
* ThePollyanna: No matter how much people torture and abuse him, he always goes about his day with a smile on his face and skip in his step.
* TooDumbToLive: Loves playing in traffic.
* TooKinkyToTorture: He seems to ''like'' everyone treating him like crap.

!!As a Whole

* AcademicAlphaBitch: Male variants.
* AnnoyingLaugh: The Spiffies all laugh and simultaneously snort, which is especially funny since all 5 of those animals have [[GagNose interesting noses]] to snort with.
* BearsAreBadNews: The very utterance of their name, makes everyone cringe in fear and hatred.
* BrainyBrunette: Every member, except Nestor has the same brown hairstyle.
* TheDreaded: As noted in one episode, it's not recommended that one barrows from the Spiffies because they tend to ask for favors in return. Likewise, the other students hate the idea of being in a class with them.
* CoordinatedClothes: Nerdy glasses, white buttoned shirt with pens in the pocket, and neatly combed brown hair.
* FiveManBand: Only every member is [[TheSmartGuy the smart guy]].
* ForScience: Their motives for the nerdy things they do.
* FourTemperamentEnsemble: Sanguine.
* GagNose: Every time they snort, (which they do a lot), we get to see a bottlenose, a snout, a trunk, a tentacle suction, and a beak in action, which makes it funnier than seeing this coming from a regular human or even animal noses.
* GivenNameReveal: The first and last names of every individual member was revealed in "Lame Brain".
* HiveMind: Act like this sometimes.
* NerdGlasses: The entire gang wears this.
* PlotAllergy: In "That Darn Platypus", everyone (except Phineas) was allergic to fruit.

* AccentUponTheWrongSyllable: Always says pronounces Adam's name as "A-DUMB", so that he can mock his stupidity.
* TheBully: He's a rare example of a ''nerd'' being one of these, being an InsufferableGenius who lords his intelligence over everyone, especially Adam.
* {{Catchphrase}} : In "Shark Fin Soupy", it was "How Cliche."
* DeviousDolphins: Of the bullying InsufferableGenius sort.
* ExtravertedNerd: Doesn't seem to care about being humiliated.
* FourEyesZeroSoul: Phineas is considered the most [[ForTheEvulz unnecessarily cold hearted]] member of the team, having gone out of his way to ruin the lives of Adam and Jake. Examples include when Phineas tried to win the last Princess Ballerina Snowglobe in stock, just because he knew Adam would want it or when he let him borrow a pencil, just so he could ask him to do dark and criminal favors, just to do his bidding.
* FriendlyPlayfulDolphin: Subverted. Phineas is fiendish to anyone who's not Mr. Blowhole or another Spiffy, and has no time to featherbed with such childish nonsense.
* GadgeteerGenius: In "Pants in Space", he invented a bunch of giant, fully functional space-travel-related machines without a sweat.
* HerCodeNameWasMarySue: Phineas has fantasies of himself, being a [[KnightInShiningArmor brave and valiant medieval knight]], who defeats dragons and saves the lives of princesses. His code name is "Sir Chancy of Glendale".
* HeroicDolphin: As mentioned before, he's this in his fantasies, only a bit more of an anthropomorphic variation, with his heroism being in an on land flesh and bones environment, instead of underwater.
* HollywoodNerd: For an anthropomorphic dolphin, he doesn't look too shabby.
* InsufferableGenius: Phineas has quite the large opinion of his intellect.
* KnightInShiningArmor: Often cosplays at this, having a fascination for medieval, renaissance stuff. In his head, he's the brave and heroic leader of a team of knights, known as "The Knights of the Multiplication Table".
* TheLeader: Phineas is this of his fellow nerds: [[ShownTheirWork a pig, an elephant, a squid, and a parrot]].
* TheMiddleAges: Obsessed with this time period. It's related to virtually every one of his tabletop games and cosplay characters.
* NonindicativeName: Though Phineas Dolphin doesn't quite have the same roll off the tongue.
* SapientCetaceans: He is a dolphin, after all.
* ShamelessSelfPromoter: The worst of the bunch.
* ShownTheirWork: Real bottlenose dolphins are famous for their intelligence and infamous for having many less than amiable behaviors. Hence, Phineas combines those two traits and becomes a nerdy version of [[TheBully the bully]].
* SicklyNeuroticGeek: Talks like this.
* SmartBall: Seems to know pretty much everything. So long as it's about [[BlandNameProduct Prisons and Lizards]], that is.

* GoodWithNumbers: Calculated how many minutes of school they had left before they graduated.

* PigMan: No explanation needed.
* RiseOfZitboy: Marvin's face is covered in pimples and zits.
* SicklyNeuroticGeek: Always sounds nasally congested.

!!Aloysius Elephant
-->'''Voiced by:''' Creator/GreyDelisle

* TheBigGuy: The largest of the group.
* BracesOfOrthodonticOverkill: Only one on the team with braces.
* EvilGenius: Seems to be the one who operates the most technology on the team.
* GagNose: His trunk.
* NerdsAreVirgins: Was able to repel a school of [[EnthrallingSiren sirens]] away, with his girl-repelling nerdyness.
* NerdyInhaler: Used this as a weapon in "Knights of the Multiplication Table".

* ButtMonkey: His being in a fish tank, makes him prone to tipping over and spilling.
* ChildrenAreAWaste: His quickness to motion sickness keeps his parents from ever going on vacations, knowing they can't take their son on a boat, plane, or excessively long car trip.
* {{Cthulhumanoid}}: Technically qualifies, though he's not nearly as threatening or badass as the usual version of this.
* IronicFear: Despite being an aquatic animal, is afraid of going on boats, because it quickly nauseates him.
* MobileFishbowl: Daniel is pushed around in a cylindrical fish tank on wheels.
* PlotAllergy: In "Knights of the Multiplication Table", he was unable to steer a boat, due to his extreme sea sickness, forcing Adam to take the wheel for plot reasons. However, this would also mean, he'd be unable to ride the boat too, without getting sick, which he was effortlessly able to do right afterwards.
* SuperNotDrowningSkills: His species allows him to thrive off of this, though this is also subverted, with him not being able to breathe in regular oxygen.
* UnfortunateName: His last name is a kind of food, made from squid that's been caught, chopped up, fried and served for dinner.

!!Nestor Parrot

* AmbiguousDisorder: Has a long list of bizarre allergies and rashes.

* PunnyName: His name being "Nestor" is a pun on him being a bird, a species which is known for building nests.
* TheRuntAtTheEnd: Very rarely, but he's sort of the odd one out. One thing that sets him apart from The Spiffies, appearance wise, is that he's the only one on the team, who doesn't have [[BrainyBrunette neatly combed, shiny brown hair]] that looks the same as everyone else's.
* ToonPhysics: In "Knights of the Multiplication Table", he randomly split himself in half.
* ToothyBird: He's been shown to have teeth on a few occasions.

* {{Catchphrase}}: "As it is wished for, so it shall be."
* TheCuckoolanderWasRight: A complete wacko, who's head is always up in space, yet what he says is actually very true and often important to the story.
* EverythingsBetterWithRainbows: David leaves behind a rainbow stream of light, wherever he flies.
* FishEyes: As a fish, his eyes go off in different directions.
* {{Flight}}: Apparently has the ability to fly through the air. Although this power is pretty useless, as he can't leave the water, without suffocating.

* AntiVillain: May have been kind of a [[StalkerWithACrush crazy obsessed lover girl]] to Adam, in her defining episode, but she was really just doing this cuz Adam was her first boyfriend, and she was both excited and anxious about messing things up, so she didn't know how annoying she was being.

[[folder:Dickie Sugarjumper]]

* GranolaGirl: Deidre is on a strict all-eucalyptus diet.

[[folder:Corey Vulture]]
--> '''Voiced by:''' Creator/TomKenny

A female dolphin and the bitchy and snobbish captain of the CDMS Jungle Squad.
* AlphaBitch: She can be a real stinker at times.
* BeautyIsBad: It's tricky to distinguish portrayals of "beauty" and "ugly", since the cast is 90% comprised of animals, but Donna seems to be the kind of girl, that if she was human, would be the so called "pretty girl" at Charles Darwin Middle School.

* TheComicallySerious: Takes everything seriously, but nobody takes him seriously.

* EmptyShell: Became this, when getting sued in "Leaf of Absence".
* {{Expy}}:
** [[WesternAnimation/TheSimpsons A cartoon principal who can't be taken seriously and is still babied around by his mother]].

Though, if anything, this can be passed off as a ContinuityDrift.
* InSeriesNickname: "PF".
* InappropriateRoleModel: Gives Adam bad advice, misleads the students of CDMS as a whole with false information, and often exhibits inappropriate behavior that's in direct violation of not just the law, but also of his own rules.

* TheNapoleon: He's a tiny frog that's in charge of the whole school.
* NoCelebritiesWereHarmed: Principal Pixiefrog is said to be based off of some kind of comedian. Some say he's a parody on Mr. Bean, due to their similar attire.

* NostrilShot: Parodied in his Literature/TheOutsiders movie audition tape.
* NotAMorningPerson: In "The Morning Zoo", he had a [[MorningRoutine daily routine]], where he'd rummage into the office, throw his hat in Mrs. Warthog's face, and give a completely disrespectful, apathetic announcement.

* PintSizedPowerhouse: He once beat a rhinoceros in a wrestling match.

* RunningGag: His car seems to be the [[ButtMonkey inanimate object butt monkey]] of his life, constantly being destroyed, broken apart, deconstructed, etc. throughout the series.

* TheComicallySerious: Carries the exact same stoic expression and bored voice, even when she claims that she's having fun.

* CommunicationsOfficer: Principal Pixiefrog's phone receptionist.

* TheSheriff: In "My Fair Lyon".
* TakeThisJobAndShoveIt: Has done this a number of times. The biggest one was in "Glazed and Confused", when it actually affected people. It turns out, she's the only person in the school, who knew how to file.
** Jake and Slips (two idiots), knew how to file, as seen in "Bad News Bear" and "Mellow Fellows", respectively, but they were all the way on another island at this point of the episode's plot, conveniently filling in for a plot hole, that the writers likely missed out on.

* TrademarkFavoriteFood: Chocolate, which she'll devour upon command.
* WastebasketBall: She can be seen playing this in her free time, ... and work time.

* GagNose: His horn.
* GentleGiant: He's a rhino who's a good guy.

* PercussiveTherapy: At their very worst, he prescribes this to patients.
* PhonyDegree: It's learned in "Mandrill of the House", that he was never a certified guidance councilor. Most likely, he was chosen for the job because the penny-pinching Pixiefrog knew he'd be cheaper than a successful college graduate.

* RippedFromThePhoneBook: Did this to show everyone, his phone number in "That Darn Platypus".

* AttentionWhore: Her living in emulating actors either on camera or in front of large audiences, mixed with her stand-alone melodrama, makes her a perfect example.

* DramaticSpotlight: Miss Chameleon is usually sitting under a heat lamp, which resembles a spotlight, connecting to her dramatic personality and constant acting like she's on stage.
* EveryoneHasStandards: She's known for taking drama class overboard, by making the acting all to real, but she still draws the line at some point. In "Making the Grade" she loved how students were sleeping, which mirrored one of Shakespeare's plays, but she got sick of it after it had been happening for an entire month. Also, in "Animal School Musical", she got sick of singing constant musical numbers all day, which is something she, as an actor, would normally love. Yet, she still begged for the end of it all, even bargaining to stop teaching acting.
* FaceYourFears: Faced her fear of heights in "A Mid Semester Life's Dream".
* FishEyes: Her eyes are always looking off in different directions and moving constantly.
* HollywoodChameleons: It's actually quite funny how well she fits into the "Hollywood" part of this, given how she's all about acting. This was done perfectly in "A Mid Semester Life's Dream", where she wanted to be a Hollywood star, but first had to learn how to change a bunch of rainbow colors and strange patterns.
** One might say this could have been a parody on the trope, but it's highly unlikely, since this episode aired in 2008, Wiki/TVTropes wasn't as popular back then.
* LargeHam: Her voice can go eerily high.
* MentorsNewHope: Adam was her last hope for a decent actor for a play, before Jake swooped in and ruined everything.
* NonMammalianHair: Her veil functions as hair, as flashbacks show her with her veil in the shape of a woman's hairstyle.
* PetitePride: Very proud of herself, despite being one of the smallest teachers at the school, outranking only Principal Pixiefrog and ''possibly'' Miss Loon or Coach Gills out of her bowl.

[[folder:Coach Tiffany Gills]]
-> Voiced by: Brian Doyle-Murray

A deep-voiced goldfish and the school's gym teacher.
* ArtEvolution: In [[https://vignette.wikia.nocookie.net/mygympartneramonkey/images/d/d3/Coach_Gills_Concept_Art.jpg/revision/latest?cb=20171201125828 original concept art]], she was a less cartoonish, representation of her species, being an expressionless goldfish with unfocused eyes on both sides of her body and a more fish-like mouth, that only opened and closed without moving it's lips in a more human way. She lacked her bow and supposedly Horace. Originally, she was also intended to have an "aquarium castle" in her fishbowl.
* BadBoss: Shows little to no respect for Horace and eagerly puts down her students with personal insults.
* TheCobblersChildrenHaveNoShoes: Coach Gills is a gym teacher (and a fish) who can't swim.
* DidIJustSayThatOutLoud: A running gag with her, throughout "Lie, Cheetah, Steal", was where her embarrassing [[InnerMonologue inner monologues]] about her love for the Mr. Cheetah, [[FourthWall could be heard by everyone around her]].
* DodgeballIsHell: And she knows it. She secretly used this to the disadvantage of Ding Bang Panda Bear in "Bad News Bear". Upon hearing how he'd become so notoriously hated and for good reason too, she thought it'd only be doing justice, to let him suffer the pain of being put in a dodgeball team, where everyone was against him.
* DrillSergeantNasty: Her voice is only one octave lower than the hardass hostility of Superintendent Wolverine's all-dreaded screaming.
* DrivenToSuicide: Twice. In "Inoculation Day", she was cornered in the bathroom stall by a monkey-hormone-charged Adam Lyon. Without anywhere to go, immobile, and Horace-less, she had no choice but to flush herself down the toilet. In "Amazon Kevin", she was again terrified by the entry of animal abusing Amazon Kevin, which got her to leap out of the bowl and flop offscreen, where there must have been a [[BehindTheBlack really close by toilet]], which she flushed herself down.
** When the latter happened, Principal Pixiefrog had to call in a substitute teacher, [[ReplacementGoldfish and would keep it a secret from the students that the sub wasn't the same as the original Coach Gills]].
* EmbarrassingFirstName: The name "Tiffany", just doesn't make you wanna straighten up and do push ups, does it?
* FishEyes: Appropriately.
* ForgotICouldntSwim: Even though she's a goldfish, Coach Gills can do nothing more than go short distances and float in place, just above the floor of her fishbowl.
* FourTemperamentEnsemble: Choleric.
* GymClassHell: She makes it this sometimes.
* IJustWantToHaveFriends: In "The "A" Word" and "The Magic Fish", it was revealed she had no friends and was desperate for a companion.
* LadyLooksLikeADude: Both in-universe characters and some of the show's fans have assumed she was male, before knowing enough information about her.
* LargeHam: She almost always talks in a loud voice.
* MistressAndServantBoy: The mistress to Horace's servant boy.
* MobileFishbowl: Teaches from a bowl wheeled around by Vice Coach Horace.
* TheNapoleon: She's a tiny goldfish who is aggressive.
* NotSoDifferent: In "Le Switcheroo", Adam and Coach Gills had a falling out, claiming that they were being too much for each other to handle. After a classic [[InAnotherMansShoes walk in each other's shoes]] (or roll in each other's bowls), they learned that both of their lives were a living Hell and started being a little nicer to each other.
* OhCrap: Coach Gills did a [[UnusualEuphemism substitute swearing]] version of this in "Synch or Swim".[[note]]This aired on a children's TV network back when "crap" was still considered a swear word.[[/note]] When Jake was hurling down toward the pool with a butt bomb, she said "[[JustForPun Oh, Carp]]".
** This is an example of a kid's show literally [[GettingCrapPastTheRadar getting "crap" past the radar]], more or less.
* PhysicalFitnessPunishment: A big user of the classic "Drop and give me 20!" punishment.
* SadistTeacher: Sure gets a thrill out of making her students work their tails off.
* SuperCoach: Before the events of "Lyon of Scrimmage", Adam wouldn't care less, in fact, would've hated the idea of being on the school football team. But thanks to Gills' training and encouragement, Adam soon became the proud team quarterback.
* TertiarySexualCharacteristics: If it weren't for these, people probably wouldn't know she's a female.
* VocalDissonance: One wouldn't expect a goldfish to have such a deep voice, much less coming from a female.
* WelcomeToMyWorld: Adam got insight to Coach Gills' life and learned how much torture she went through. She has tons of paperwork to sign, which is next to impossible for her species, she gets tons of calls from a bunch of [[DrillSergeantNasty drill sergeant nasties]], and of course, has to put up with a bunch of rotten kids every class period.

[[folder:Vice Coach Horace Ferret]]
->Voiced by: Creator/Robert Goulet

Coach Gills' ferret assistant.
* BeleagueredAssistant: Does about 99% of the work around the gym and gets 0% of the credit, even pushing the [[MobileFishbowl mobile fishbowl]] that Coach Gills sits in around.
* {{Butlerspace}}: If a scene doesn't require Coach Gills to move, Horace will be nowhere in sight.
* ButtMonkey: Though not to the extent as other teachers in the show, he sure has seen better days. He's consistently treated like crap by his boss and does nothing to get revenge on her, in "The Magic Fish", he was put down by her, as his only companion, when she said she had no friends, and in "Lie, Cheetah, Steal", he was put into a neckbrace, after being overworked by another gym coach friend of his. [[ContrivedCoincidence While in traction, he also pushed a push pop out of it's socket, making it land on his face]].
* CockFight: [[spoiler:Ended up being Jake's surprise competition for the heart of Ms. Slender Loris in "Substitute Sweetheart", and effortlessly won.]]
* CuteMute: A cute ferret who doesn't speak.
* FlatCharacter: Says nothing and rarely does anything, not [[SatelliteCharacter related to Coach Gills]].
* FourTemperamentEnsemble: Phlegmatic.
* HeelFaceTurn: In "Glazed and Confused", he put Coach Gills' bowl outside, allowing for birds to attack her. She called him many times to let her back in, but he just stood there and smiled.
* HiddenDepths: It's revealed in "Animal School Musical", [[spoiler:his reasons for being silent all the time is because he doesn't like the sound of his voice]].
* HyperCompetentSidekick: Although, he doesn't have the voice of Coach Gills by any means, he's a lot smarter than her, and his wisdom, is of course, always ignored.
* MistressAndServantBoy: The servant boy to Coach Gills' mistress.
* PerpetualFrowner: His standard facial expression is a seemingly blank stare into space with an emotionless frowning mouth that rarely ever seems to move or change.
* SatelliteCharacter: To Coach Gills.
* SelfDeprecation: [[spoiler:Admittedly, doesn't like his own voice]].
* SilentSnarker: His facial expressions convey snark.
* SycophanticServant: Although he's generally on the top of his game, he did screw with Gillsy in the Christmas special, where he'd keep playing a radio, to make it rhyme with everything she said, even though she asked him time and time again to stop.
-->'''Coach Gills:''' Don't make me hurt you, Horace.
** At the end of the episode, he clogged her bowl with a loaf of bread, to silence her voice.
* TheVoiceless: His mail deal is that he never talks, which contrasts greatly, with Coach Gills' constant screaming and endless blabbering. [[spoiler:He was [[SuddenlyVoiced suddenly voiced]] in "Animal School Musical".]]
-->'''Horace:''' I don't ever talk, but now I don't have a choice. It's really quite awful cuz I don't like my voice.
** It should also be noted that the actor they chose to voice him in this one appearance, died before the production was aired. An [[InMemoriam "In Loving Memory" card]] was dedicated to him. It's just kind of eerie, to see how the voice actor of the character who never talks was dead, when his speaking episode was aired.
* VitriolicBestBuds: With Coach Gills. He is constantly tormented and tossed around by his boss, not doing a thing in response. However, in episodes such as "Glazed and Confused", he was shown to take pleasure in knowing that Coach Gills was being eaten alive by wild crows and just smiled, while he sat back and let it happen.
* WeaselMascot: The Ferret Mascot of Coach Gills.

[[folder:Mrs. Eugenia Tusk]]
->Voiced by: Creator/CreeSummer

The African-Elephant lunchlady, known for her food being delicious for all the animals who eat it, but disgusting to Adam.
* AllLoveIsUnrequited: [[spoiler:Does not return Mr. Hornbill's feelings for her, as she is married.]]
* AmbiguouslyBrown: Her accent would imply that she's Jamaican, meaning a human version of her would be dark skinned, right? However, in "The Times, They Are Exchangin'", a human version of her actually did appear, and she was completely Caucasian.
** [[RaceLift Whitewashing]], much?
* ApatheticTeacher: Doesn't really give a shit about serving lunch to kids. Only does it for the money, what little she makes. Especially considering her boss, being the Mr. Krabs of Charles Darwin Middle School.
* AnimalFacialHair: A rare, but sad, female example for her. She has a thick black hair sticking off of the already horrendous looking mole on her face.
* BeautyMark: Subverted. She has a big black mole on her cheek, right where a beauty mark on a hot person would go.
* CampCook: The cafeteria lunchlady variant of this.
* {{Catchphrase}}: "Aw, nuts."
* ChubbyChef: Granted, she's an elephant, so she's not exactly going to be a Slim Jim.
* ClownCar: She drives a tiny blue car, that she can barely even fit into. Her ears flop out the side windows and she apparently dismantled the windshield just so her trunk could have some breathing room.
* CordonBleughChef: The food she makes, seem to be a mixture of animal foods and human food. For example, one of her most famous dishes is "Wormy Joes", which are basically [[ExactlyWhatItSaysOnTheTin sloppy joes with worms in them]].
* CorruptCorporateExecutive: In "Law and Odor", she took part in the corruption of the Hall Monitors, offering them free food if they were to be a little more "attentive" to any problems that may go on near her lunchroom. Also, in "Yesterday's Funny Monkey", she was clearly [[OnlyInItForTheMoney in it for the money]], when she opened up the "Laugheteria", and raked in dough, while Jake performed for an audience. A shot even showed her holding [[ThiefBag two big bags of money]] and making [[EvilLaugh villainous laughter]], proving herself to be just about as low down as Principal Pixiefrog.
* FanDisservice: Dressed as a French Maid in "Uniformity".
* FatAndProud: Given that she is in fact an elephant, she doesn't have the need to feel even the slightest bit ashamed of her weight. This was all until "Chew on This", when she stuffed herself to obesity, after guzzling down a ton of fatty food and had to run laps around the school.
** It should also be noted that this food came from another manufacturer, when Adam complained about the food she made. Just goes to show that [[TheCobblersChildrenHaveNoShoes even she agrees that her cooking sucks]].
* FiredTeacher: Was [[NoodleIncident inexplicably]] fired and [[GeorgeJetsonJobSecurity rehired]] again, as a side-joke at the beginning and end of "The Notorious Windsor Gorilla".
* FourTemperamentEnsemble: Phlegmatic.
* FunnyAccent: Jamaican.
* GagNose: Her trunk.
* GentleGiant: A tall, kind sort.
* LethalChef: A pretty horrible cook. All of her food is near inedible and seems to gross out everyone except for Jake.
** A small Easter egg was shown in "Animal School Musical", where one of the items on her menu was a carton of milk with "Swill" on the label. This is a reference to the [[https://en.wikipedia.org/wiki/Swill_milk_scandal Swill milk scandal]], in which cows were fed leftover mash, collected from liquor factories and then milked, while sick, leading to the a genocide in New York in the 1850's. So basically, Mrs. Tusk is serving food that could get her students killed.
* LoveInterest: To Mr. Hornbill [[spoiler:(despite the fact she's married)]].
* MysteryMeat: Pretty much everything she cooks.
* PinkElephants: Literally.
* TenMinutesInTheCloset: Thanks to Adam and Jake, she got into this situation with Mr. Hornbill.
* VillainousGlutton: Taken to extremes in "Chew on This". Her most vile moment was denying Adam a corndog, saying they were all out [[ILied only for her to eat one after he left]].
-->'''Mrs. Tusk:''' Yes, yes. Come to Mama.
* WeddingRingDefense: Played with. [[spoiler:She's married, but her [[RealityEnsues elephant hands are so big, she can't wear a wedding ring]], which allowed Mr. Hornbill to think it was fine to hit on her.]]

[[folder:Miss Loon]]
->Voiced by: Creator/CreeSummer

The art teacher, with no appreciation for fine arts.
* ChuckCunninghamSyndrome: Despite being established as the art teacher in various episodes, it was said by Principal Pixiefrog in "The Notorious Windsor Gorilla" that "the school's never had an art class." This could be seen as a simple [[ContinuityDrift continuity drift]], but it really shows how little they cared about her, if they blatantly forgot about her existence in this episode.
* TheCobblersChildrenHaveNoShoes: She dispises any artwork that's actually good. If one of her students were to, for instance, make a perfect recreation of the Mona Lisa, she'd scoff at it for being unoriginal.
* DemotedToExtra: Originally cast as one of the main/recurring school faculty members, but with every passing season, her prominence became more and more spotty, to the point, where she was never even talked about anymore. Faculty-Centric episodes such as "Robo Frog 3000" and "Glazed and Confused", featured pretty much everyone except for her.
* {{Expy}}: It's said her character is an allusion to Ethel Taylor from Theatre/OnGoldenPond, who's known for her love of loons.
* NonIndicativeName: She's actually a blue jay.
* SeldomSeenSpecies: Whether she's a blue jay or a loon, she still counts.
* ToothyBird: Averted. And arguably the only bird in the series, with no teeth.
* WithFriendsLikeThese: In "A Very Special Boy", her friend, Mrs. Warthog showed absolutely no respect for her.

[[folder:Nurse Jacqueline Gazelle]]
->Voiced by: Creator/GreyDeLisle

The school nurse.
* TheAllSolvingHammer: Hypodermic needles.
-->'''Adam:''' I'm allergic to needles.
-->'''Nurse Gazelle:''' Well, I got nothin'.
* BackAlleyDoctor: Nurse Gazelle doesn't know what half her doctor equipment even does and usually ends up putting her patients in more pain than they came in with. As a matter of fact, she isn't a certified doctor, or even a certified anything, having dropped out of middle school. She was only hired because Principal Pixiefrog wanted to save a few bucks on a real school nurse, as usual.
* BackToSchool: When her middle school dropout story was discovered by Principal Wolverine, she lost her job at CDMS, became a student at CDMS, and work her way back to to getting a job at CDMS again.
* BlowGun: Used this to inoculate kids with hypodermic needles in "Inoculation Day".
* {{Cloudcuckoolander}}: Was a bit of an airhead in earlier seasons, but [[{{Flanderization}} turned into a flat out moron]] in later seasons.
* CreepyPhysical: In "Chew on This", Nurse Gazelle was seen extracting a [[GettingCrapPastTheRadar rectal thermometer]] from Adam, when he only came to her because he felt lightheaded.
* DumbBlonde: Played with. She mentioned that she's got a brain the size of a peanut in "Inoculation Day" but, otherwise, doesn't seem to be any dumber than any of the other characters.
* GeorgeJetsonJobSecurity: Got fired, once it turned out she never graduated middle school. If this happened in real life, there's no way she'd be getting her job back again, especially not for the reasons she did. The files, proving her incapability of being the nurse were destroyed in a fire, so her superior decided to let her have her job back, despite there also being no evidence that she ''was'' qualified and the fact that he already knew she wasn't.
* GreenEyedMonster: Ingrid was jealous of her beauty, popularity, and "closeness with Adam" when she became a student in "Lyon's Anatomy".
* HotForStudent: Has a crush on Adam Lyon. It started in "Poop Scoop", when false news was spread that Adam was in love with every female teacher at CDMS, which sparked her and every other female teacher's interest, making them all surround Adam, wanting to know more. Unlike with other teacher, however, this must have stuck and gone a bit too far, as she admitted to having a crush on him in "Lyon's Anatomy".
* IdiotBall: Has about the same I.Q. level as Slips.
-->'''Principal Wolverine:''' ''[furious]'' Ms. Gazelle! Give me one good reason, why I shouldn't revoke you of your career!
-->'''Nurse Gazelle:''' ''[unfazed]'' What's a career?
* JerkassBall: Some fans claim she passed the [[MoralEventHorizon moral event horizon]], when she tried to shave Rufus's hair off for no reason in "The Hyena And The Mighty".
* LovableAlphaBitch: When she became a student in "Lyon's Anatomy", she fell into this archetype. She spread gossip about other students' medical conditions and took subtle shots at Ingrid, because she was after the same man she was. However, as soon as Ingrid confronted her, she suddenly became her friend out of nowhere.
* LoveMakesYouEvil: In "Lyon's Anaomy", she became a bit of a [[AlphaBitch bitch]], especially to Ingrid, done mainly out of her love for Adam.
* MadDoctor: In "The Hyena and the Mighty", she went cuckoo and tried conducting an experiment with shaving all of Rufus' fur off.
* TheMedic: Due to being a school nurse.
* MrsRobinson: Has the hots for Adam.
* NaughtyNurseOutfit: Played with in "Lyon's Anatomy".
* SchoolNurse: Duh.
* SwiperNoSwiping: Put an end to Ingrid's furious hatred for her, just by explaining their differences and offering for them to make up.
* WoundedGazelleGambit: Ironically, if a someone does this, (i.e. faking suck) it'll totally work on her, just like the trope should.
* YouWontFeelAThing: This should be her motto.

[[folder:Mr. Blowhole]]
->Voiced by: Creator/DeeBradleyBaker

An Orca whale who is usually seen as the teacher of the nerds. Accompanied by whale noises whenever he talks.
* AmbiguouslyEvil: In "The Spiffanos", The Spiffies formed together as a mafia gang, that enforced crime and corruption in the school. Phineas, the leader of the gang, mentioned Mr. Blowhole as the higher-up, which could imply that Mr. Blowhole is the [[GreaterScopeVillain greater scope villain]], running a whole network of gangs such as theirs. Of course, this is all just assumption, as Mr. Blowhole never actually appeared in that episode.
* ApatheticTeacher: Only, when he puts up with anyone, other than The Spiffies.
* TheBigGuy: The biggest faculty member, and likely the largest member of the school, outranking Endugu Elephant's record of the largest student in terms of width.
* BiggerBad: If you consider him a Spiffy, he's this to Phineas Porpoise. Phineas may lead his group and be a domineering king of intelligence to a degree, but Mr. Blowhole is basically the [[TheDon crime lord]] of the group, and much of Phineas' actions are done in favor of his teacher.
* BrokenBird: Not that this sets him apart from half the other teachers at CDMS, but Mr. Blowhole seems occasionally depressed and overall, unsatisfied with his life. Though, this could mainly just be because of his deep, lazy way of talking. He's actually quite happy with teaching a class full of geniuses, this is, when he's not being interrupted by Jake Spidermonkey.
* ButtMonkey: Though it's not one of his overarching traits, it was mentioned via [[BreakingTheFourthWall fourth wall joke]] in "The Spiffanos" that in every previous episode, centered around him, his blowhole has underwent a ton of damage from Adam and Jake's wacky hijinks.
-->'''Jake:''' ''(chuckles)'' Mr. Blowhole's blowhole will never be the same.
* ColorCodedPatrician: The Spiffies all the same [[NerdGlasses wear thick-rimmed glasses]]. Mr. Blowhole's glasses are the same style, but they're red instead of black, proving that he really is the [[TheSmurfs Papa Smurf]] of the pack.
* DeanBitterman: Judiciously hates Jake Spidermonkey, and jumps on the chance to punish him, every chance he gets.
* GentleGiant: Referred to as this in "Robo Frog 3000".
-->'''Wizard:''' Hold me, my gentle giant.
* HeavyVoice: Being, he's a gigantic Orca whale, his voice comes out in a very deep, heavy way.
* HumanDoorstop: Used as a surfboard in "An Inconvenient Goof".
* MobileFishbowl: Mr. Blowhole moves around, by dragging himself around the school in a giant fish tank.
* PassingNotesInClass: In "The Note", these kinds of antics unfolded in his class, but he was, for the most part, unaware of it.
* RageBreakingPoint: Rarely happens to the humble guy he is, but Jake managed to push him to this in "Animal Testing", while being obnoxious during the spelling bee.
-->'''Mr. Blowhole:''' SPELL IT!!!
* SitcomArchNemesis: Has a strong, but justified disliking for Jake Spidermonkey. His antics have gotten on his nerves and [[DrivenToMadness driven him to madness]] more than once. Episodes like "Animal Testing", "Jake's Day Off", and "Knights of the Multiplication Table" provide evidence of this.
* SmartPeopleWearGlasses: Like The Spiffies, Mr. Blowhole wears the iconic "smart people" glasses. His is the only pair of glasses with a red rim, instead of black, which his students wear, [[ColorCodedPatrician signifying that he is the honorable leader]].
* SpaceWhale: Whenever he talks, soothing whalesong plays in the background, referencing to this idealism.
* TheStoic: Rarely shows emotion other than the blandness that comes from his combination of serene tranquility and hyper-focused attention to work.
* TheStoolPigeon: Ratted out Adam and Jake in "Jake's Day Off". When he saw them riding down the hallway, the son of a bitch made a phone call to Principal Pixiefrog, even though it was none of his business.
* UnfortunateNames: "Mr. Blowhole", just sounds kind of ... well, stupid to say the least.
** I'd hate to imagine what the [[{{Animorphism}} humanized]] version of him would be named.

[[folder:Superintendent (formerly Principal) Wolverine]]
-->Voiced by: Chris Edgerly

The aggressive, loud-mouthed, substitute principal teacher for Principal Pixiefrog.
* AlwaysSomeoneBetter: In "Pride and Pixiefrog", PF lost his Principal of the Year award, and it was then given to Wolverine.
** For him, he acts like the big man on campus every time he goes to Charles Darwin Middle School, but is still outranked by the Lagomporphic School Board, who can hire and fire him, whenever they want. Just goes to show that no matter how high on the corporate ladder, nobody in the business industry has ''complete'' power.
* BewareOfViciousDog: Superintendent Wolverine is just about as nasty as he sounds.
* BiggerBad: If you think Principal Pixiefrog is bad ...
** Let's also not forget to mention, how he's the only teacher capable of overpowering Bull Sharkowski. He even took his underwater headphones from him and nearly killed him.
* ButtBiter: His go-to threat for people who wrong him is biting them on the buttocks. Though [[IneffectualDeathThreats he's never actually been seen doing that]].
* DrillSergeantNasty: Runs CDMS like a military school.
* EyesAlwaysShut: Always carries two squinted-shut eyes, which are portrayed by two horizontal dashes on his face.
* FallenOnHardTimesJob: Was reduced to working at a hand-done car wash in "Robo Frog 3000".
* FangsAreEvil: Has sharp, pointy fangs.
** The better to bite people's buttocks with.
* FunHatingConfiscatingAdult: Doesn't allow people to listen to music.
* GeorgeJetsonJobSecurity: He was on the boss' end of this in "Lyon's Anatomy", easily giving Nurse Gazelle her job back, for a completely stupid reason. She got fired in the first place because files proved that she never graduated middle school, but because that evidence was destroyed, he rehired her, apparently forgetting the proof of which he'd already seen.
** Guess if you're good, the universe will reward you, as Wolverine got his job back after losing in in a later episode.
* GrumpyOldMan: Though, not really portrayed as old, he's not necessarily young either. Plus, since he seems to be a portrayal of a drill sergeant, it's possible he's some sort of a war veteran.
* HowTheMightyHaveFallen: In "Robo Frog 3000", he lost his illustrious job as the superintendent, [[JobStealingRobot to a robot]]. He probably spent years, busting his ass, and thriving to that point, and his downfall was extremely drastic, with him then having to work at a car wash, [[KickThemWhileTheyAreDown which he was also quickly fired from, after being replaced by a robot]].
* InsaneAdmiral: He can be completely off his gourd at times.
* {{Jerkass}}: The way he treated his students in the hallway was unbelievable. Not only did he nearly kill Bull, but he also yanked the nose ring out of a bull student, which ripped her skin, and told her that jewelry wasn't allowed at CDMS.
* NewJobAsThePlotDemands: Was promoted from vice principal to superintendent in "Lyon's Anatomy", so that he could be in a position to fire Nurse Gazelle.
* NoIndoorVoice: Has never been heard, not screaming.
* OutOfCharacterMoment: Although he's a always a cruel, cold-hearted, hardass, his final moment in the episode, was him taking out a [[ParasolParachute Mary Poppins umbrella]] and floating off with it, like a [[MagicalNanny magical nanny]].
* TheNapoleon: Bigger than Principal Pixiefrog, but still has to look up to Adam, when giving him lectures.
* VerbalTic: Pronounces "Graduate" as "Grad-jee-ate".
* WorkplaceAcquiredAbilities: Using the abrasive bossiness he specialized in at his former-at-the-time job, he was able to take down the Robits, and get his job back.
[[folder:Kerry Anderson]]
->Voiced by: Creator/CreeSummer
Adam's love interest, best human friend, and former classmate at Chester Arthur Middle School.
* ActionGirlfriend: Showed off her skills in "Glazed and Confused".
* AlmostKiss: She and Adam have attempted to kiss before, but it's always interrupted either by outside disturbances or one of them pulling back.
* AmbiguouslyBrown: Her [[Creator/CreeSummer voice actor]] is black, making it likely, though compared to other black humans in the show, she looks more Hispanic or Latina.
** Given how she's an {{Expy}} of Abigail from Kids Next Door, it's possible that she was intended to be black.
* BareYourMidriff: Wears crop tops even to school.
* CharacterDevelopment: In the first seasons, she was mainly just a [[LoveInterest love interest]], [[FlatCharacter who's only role was for Adam to have a crush on her]]. However, season 4 episodes such as "Glazed and Confused" and "Human Behavior" give us a lot of insight to her life and personality.
* TheCheerleader: She's part of the Chester Arthur Middle School "Peppy Pep Girls".
* TheCommissionerGordon: Adam's only connection with the human world.
* CommitmentIssues: In "Glazed and Confused", she was hesitant to kiss Adam, despite being in love with him.
* CoolKidAndLoserFriendship: Chad often chides her for being friends with Adam.
* {{Cyclops}}: It's been joked by Jake and Principal Pixiefrog, that she's a cyclops, since only one of her eyes is ever shown.
* DeadpanSnarker: When in a bad mood, or when she realizes [[NoRespectGuy that nobody's gunna listen to her, no matter what she says]], she can make a few witty comments about the [[StraightManAndWiseGuy wise guys]] of the scene.
* {{Expy}}: Kerry has the same [[Creator/CreeSummer VA]] as Abigail "Numbuh 5", from [[WesternAnimation/CodenameKidsNextDoor Kids Next Door]], with not many changed between voices. She has a sort-of-but-not-too-much similar appearance, and tends to be reminiscent of her at times.
* GirlOfMyDreams: Adam dreamed about playing paintball with her in "Up All Night".
* HeroesWantRedheads: She has a crush on Adam.
* {{Love Interest|s}}: She's one of Adam.
* MasculineGirlFeminineBoy: In "Glazed and Confused", she led a team, and fought a tribe of cannibalistic islanders, [[DamselInDistress to save Adam]].
* NiceGirl: Acts pretty kind with Adam, even when the animals make things get crazy.
* PeekABangs: Her other eye is never seen. So much so, that it turned into a running gag in season 4.
* PuppyLove: They make an adorable couple, and have great chemistry, but they're 11 years old, so it'll never last.
* RunningGag: Adam and Kerry [[AlmostKiss almost kissing]], but then failing for some reason.
** In later seasons, it became a recurring joke to mention "one eye".
* SpellMyNameWithAnS: Fans assume her name is "Carrie" or "Carey" or various other spellings. Fortunately, for the fanbase, the episode "Up All Night" provides us with ''(possibly the only instance of)'' her name's spelling, which is the slightly less popular, "[[AerithAndBob Kerry]]".
* TomboyishName: When you see her name spelled, you'll notice it's spelled "Kerry", which although it's unisex, is mostly a guy's name.

->Voiced by: Creator/TomKenny
Adam's former school bully from Chester Arthur Middle School.
* AndThenWhat: In "Lonely Lyon", he realized there was nothing to do at school, now that Adam was gone and he desperately tried to bring him back into his life again, so he could feel the joy of bullying him again.
* TheBadGuyWins: Usually the case, in episodes such as "Supplies Party" and "Docu-Trauma".
* TheBully: Whenever Bull Sharkowski isn't around.

* {{Determinator}}: In "Lonely Lyon", Chad dressed as a bear and transferred to CDMS, just to continue bullying Adam.
* FriendlyEnemy: Judging by his obsession with Adam in "Lonely Lyon", it wouldn't be a stretch to say that he's developed some kind of affection for bullying him, specifically.

* LadyLooksLikeADude: Looks suspiciously similar to Jake.
* NewTransferStudent: The story behind her comically abrupt debut.

* DemonicDummy: If the {{Stinger}} of his title episode means anything.
* OrganAutonomy: Teddy Truman seems to have a mind of it's own.

This includes physical violence, emotional pain, and overall, just ruining Windsor's life.
* {{Pun}}: Teddy Truman lives off of these.
* PunnyName: His first name is a pun on the fact that he's a toy, depicting a bear, making him somewhat of a "Teddy Bear".

* TertiarySexualCharacteristics: When they "appeared" in "Where in the World Are Adam's Parents?", they were wearing hazmat suits that covered their entire bodies. Adam's mom had visible breast lumps on the front of her suit, which was the only thing, setting her apart from Adam's dad.

** Adam's grandma's voice was heard, however, we do see her with most of her body out of view (we see her hand pointing).
* WhenYouComingHomeDad: Adam's parents work so much, they don't arrive home until extremely late at night. Adam has to fix his own dinner and is usually asleep by the time they're home. His mom even missed his birthday, being stuck at work.

* InnocentlyInsensitive: Jake's dad insults his wife and son a lot, though he doesn't seem to understand how what he's saying comes across as offensive. Rather, to him, they just sound like regular comments.

-->'''Jake's Mom:''' ''[flattered]'' Me? Oh no, not me.
