!Main Characters
!!Chyna Parks
->'''Portrayed by:''' Music/ChinaAnneMcClain

* TheAce
** BrokenAce: She's not very good at math.
* [[BigLittleBrother Big Little Sister]]: She's taller than her older brother Cameron.
* TheCastShowOff: She gets to sing at least once per episode. It's even {{Lampshade|Hanging}}d by Lexi in "[=chANTs=] of a lifetime".
-->'''Lexi:''' I spent $400 on tickets to see ''you'' sing? I see that every day for free!
* {{Expy}}: Of [[Series/ThatsSoRaven Raven Baxter]], [[Series/{{ICarly}} Carly Shay]], and [[Series/{{Victorious}} Tori Vega]].
* FoolishSiblingResponsibleSibling: The Responsible to Cameron's Foolish.
* GenkiGirl
* TheHero
* HeterosexualLifePartners: With Olive.
* IdolSinger
* LittleMissSnarker
* NiceGirl
* NotSoAboveItAll: Chyna can be really selfish sometimes.
* OnlySaneWoman
* PluckyGirl
* [[SassyBlackWoman Sassy Black Girl]]
* ShipperOnDeck: For Fletcher & Olive, as seen in "[=patANT=] pending".
* SlapstickKnowsNoGender: Though she doesn't have it as bad as the main male cast.
* TeamMom: The other A.N.T.s don't depend on her for nothing.

!!Olive Doyle
->'''Portrayed by:''' Creator/SierraMcCormick

* {{Adorkable}}: Not entirely the stereotypical dork, but she has a large brain capacity, which she fills with very advanced subjects such as physics and calculus, she finds homework and extra credit assignments fun, is the youngest person ever inducted into Mensa and has long blonde hair, and a StalkerWithACrush although it's just Angus.
* {{Adorably Precocious Child}}
* AntiHero: More so in season 3.
* [[spoiler:AwkwardKiss: She gets one from Fletcher at the end of ''unw[=ANT=]ed''.]]
* CatchPhrase: "What the heck?!" and "Interesting factoid" (and, to a degree, "Hollah!").
** Season 3 introduces "Zazzow!".
* {{Cloudcuckoolander}}
* CunningLinguist
* CuteButCacophonic: Olive speaks relatively loudly and with an overdone accent of sorts.
* TheCutie
* DitzyGenius: While very book smart due to having super memory, she has very childish moments, such as believing Cameron's ghost story, having way more fun while the rest of the [=ANTs=] are playing musical chairs, and her overall naivete. At least somewhat justified in that the character is only 12 at the beginning of the series. Maturity comes with experience.
* DumbBlonde: [[SubvertedTrope Subverted]] since she has the greatest mental capacity on the show, she rarely puts it to good use, as a result, she sometimes ends up looking dumb and childish at times. She begins to play with this trope in "[=intelligANT=]".
* {{Expy}}: Of [[HannahMontana Lilly Truscott]] and [[{{ICarly}} Sam Puckett]].
* {{Fangirl}}: Of Professor Marcy [=McLaughlin=].
* {{Flanderization}}: She went from a mere {{cloudcuckoolander}} in the first season to a full-blown {{jerkass}} later on.
* GamerChick
* GenkiGirl
* HeterosexualLifePartners: With Chyna.
* InnocentlyInsensitive
* InnocentProdigy
* {{Insufferable Genius}}: Mostly to Fletcher.
* {{Jerkass}}: In her case though, her over-analytical mind seems to give her a LackOfEmpathy, plus she's a {{Cloudcuckoolander}}. Most of her moments are directed at [[ButtMonkey Fletcher]].
* LargeHam
* LittleMissSnarker
* MotorMouth
* NoIndoorVoice: Mostly in the first season, but it still shows up at times.
* {{Photographic Memory}}: Her talent, and what landed her in the A.N.T. Farm to begin with.
* RapunzelHair
* TeenGenius
* TokenEvilTeammate: She's been developing into one in season 3, even to the point of being worse than Lexi.
* TookALevelInJerkass: From Season 2 onward Olive becomes bossier, more self-centred, and enjoys other people's pain (and doesn't hesitate to inflict pain on others either). In Season 3, it came to a point in one episode where she ended up being worse than Lexi.

!!Fletcher Quimby
->'''Portrayed by:''' Creator/JakeShort

* {{Abusive Parents}}: Implied in several instances.
* {{Adorkable}}
* {{Book Dumb}}: Yet this did not prevent him from being in the ANT program
* {{Born Unlucky}}: He's the ButtMonkey. Plus, his parents don't seem very supportive of his artistic ability.
* {{Butt Monkey}}
** CosmicPlaything: Evolves into this later on. If anyone is going to be hit, teased, thrown, slapped, yelled at, or receive dirty looks it'll be Fletcher.
* {{The Chew Toy}}: It's safe to say that Fletcher is the unluckiest ANT.
* {{Cloudcuckoolander}}
* {{Deadpan Snarker}}: He has his moments.
** He could easily be the snarkiest character on the show but his ditziness keeps him in check.
* TheDogBitesBack: Despite his status as the Butt Monkey, Fletcher proves in "feature [=presANTation=]" that he does have limits to how much he will endure. In the episode, Fletcher hasn't been able to sleep for days because Angus keeps having nightmares waking him up. He spends the episode helping him with this problem, while Angus acts like a total jerkass towards him. After his final plan to help him ends with them simulating being on a boat, causing Fletcher to still be awake and even fall in a bowl of fish, he finally snaps and, in a particularly impressive and gratifying moment, he not only stands up to Angus, but actually chases him around the school, leaving Angus able to do nothing but run and scream in terror.
* {{Dogged Nice Guy}}: To Chyna.
* {{Expy}}: Of [[{{ICarly}} Freddie Benson]], complete with being the Butt Monkey (but more worse than Freddie's). Though their personalities differ, as well as liking a specific subject (Freddie's Tech knowledge to Fletcher's Art).
* {{Flanderization}}: His ButtMonkey status is so exaggerated by Season 3 that you're more likely to see him getting hurt and insulted than actually, well, making art.
* GeniusDitz: Fletcher's great at art, but thinks snow angels are dead snowmen.
* {{Genre Savvy}}
* HorribleJudgeOfCharacter: At times, he ended up going along with the plans of villains, even when they admit their villainy. For example, he blindly agrees to paint Principal Skidmore even though she admitted to his face that she just uses the A.N.T. Farm as a sweatshop. Another example is when Lexi has Fletcher be the fall guy, so that she wouldn't get in trouble.
* {{Keet}}: "Hey Lexi, it's Fletcher from school!"
* {{Kid Anova}}: Kinda.
* LittleBoySeeksBigGirl: Fletcher occasionally tends to forget about Chyna when he's around Paisley, especially whenever Paisley hugs Fletcher. One such example (from the pilot no less) happens to be the pictured example on said Tropes page. So far it happened twice in the show, but he implied about Paisley on "[=chANTs=] of a lifetime" when he said he's moving to his 2nd best choice (since Chyna is gone).
** Does this again with Kennedy, and has a relationship with her, [[spoiler:but it turned out to be a facade.]]
* StalkerWithACrush: To Chyna.
* TookALevelInDumbass: Definitely lost more than a few IQ points from late Season 2 onward.
** DumbassHasAPoint
-->'''Olive:''' "With no rules I feel like I'm slowly dying."
-->'''Fletcher:''' "Technically we're all slowly dying, I believe it's called aging."
* WackyGuy: [[DependingOnTheWriter Sometimes]].
* ZeroPercentApprovalRating: In the ''entire'' country as revealed in ''Secret [=AgANT=]''.[[spoiler:Probably made up, though.]]

!!Lexi Reed
->'''Portrayed by:''' Creator/StefanieScott

* AlphaBitch: Although she developed into a LovableAlphaBitch later on.
* AntiVillain
* AttentionWhore: To ''amazing'' levels.
* BigBadEnsemble: With Principal Skidmore, somewhat.
* BlondesAreEvil: Downplayed. Not evil, but certainly mean and manipulative.
* CardCarryingVillain
* CatchPhrase: "Shut up, Paisley!" and "You have got to be kidding me!"
* CharacterizationMarchesOn: Becomes more of a comedic frenemy to the [=ANTs=] as the show progresses instead of a straight-up villain.
* TheCheerleader
* DiminishingVillainThreat: Though she was initially designated as the main antagonist, that gets usurped by Principal Skidmore overtime.
* FreudianExcuse: "america needs [=talANT=]" tells us that the reason Lexi makes fun of Chyna is because she's secretly worried that she isn't as good as Chyna.
** Season 3 also shows that she's something of an insecure closet geek, which actually explains a lot.
* GoodWithNumbers: How she gets into the ANT Program.
* GuiltyPleasure: Lexi had two of these: First for the Stinkles movie, and later for Glarcon, after taking a glance at the comic book.
* HeterosexualLifePartners: With Paisley.
* HiddenDepths: The Season 3 premiere reveals that she is a math genius.
* {{Hypocrite}}: Usually. Season 3 brought more light into this, as she always said she hates the [=ANTs=], but turned out to be a math prodigy. Actually, both of the above makes her more of a ClosetGeek [[FreudianExcuse who tormented the [=ANTs=] relentlessly]] ''[[YouAreWhatYouHate because she IS one]]'', [[FreudianExcuse and doesn't want others to know, so they wouldn't treat her the same way.]]
* ItsAllAboutMe
* {{Jerkass}}
** JerkWithAHeartOfGold: She has her moments.
* LightFeminineAndDarkFeminine: The dark to Paisley's light.
* LovableAlphaBitch: In later episodes.
* ManipulativeBitch: In spades.
* {{Narcissist}}: She is ''always'' looking at herself in the mirror.
* OddFriendship: With Cameron.
** She's also the character that's closest to Zoltan (other than his secretary, but even he's more chummy with Lexi than her).
* ScrewYourself: G-rated version of this at the end of "[=idANTity crisis=]".
* ShipTease: With Cameron.
* SitcomArchNemesis: To Chyna.

!!Cameron Parks

* DemotedToExtra: He's been replaced by Angus in Season 3.
* TheDitz

* FoolishSiblingResponsibleSibling: The Foolish to Chyna's Responsible.
* OddFriendship: With Lexi and Paisley.
* PutOnABus: Though he returns in "feature [=presANTation=]".
* ShipTease: With both Lexi and Paisley.
* TheUnfavourite

!!Angus Chestnut
->'''Portrayed by:''' Aedin Mincks

* AbhorrentAdmirer: To Olive and is one of the rare male cases of this.
* AdorablyPrecociousChild
* AscendedExtra: In season 3, replacing Cameron.
* BigEater

* StalkerWithACrush: To Olive.
* TookALevelInJerkass

!Recurring Characters

** GeniusDitz: Paisley is apparently able to build a ''functioning helicopter'' out of ''balloons''. Complete with a rope ladder. In two seconds.

* ZeroPercentApprovalRating: All the students hate her.
* AlliterativeName
* AuthorityEqualsAsskicking: She was placed in a room with a live bear, but she singlehandedly defeated it!
* BigBadEnsemble: With Lexi Reed. Well, not anymore as of Season 3.
* DeanBitterman: Fits the role of the mean principal really well.
* EvilRedhead: She's one of the main antagonists.
* {{Jerkass}}
* JerkWithAHeartOfGold: Only on occasion.
* NiceJobFixingItVillain: In the Season 3 Premiere, she made the school run down, hoping a billionaire inventor would fund the school for her own needs, but instead, he decided to make his own ANT boarding school and takes the [=ANTs=] under his wing, thus freeing the [=ANTs=] from Skidmore's tyranny.
* SmallNameBigEgo: She thinks to be young and beautiful, to the point where she cannot believe her own reflection is her.

!!Darryl Parks
->'''Portrayed by:''' Finesse Mitchell

* BadCopIncompetentCop

* {{Cloudcuckoolander}}
* TheDitz
* {{Expy}}: Of [[{{ICarly}} Spencer Shay]].
* FunnyAfro
* HammerspaceHair: He keeps, among other things, licorice, fresh tissues and corn cobs in his hair.
* LiteralMinded

!!Wacky The Wolf
->'''Portrayed by:''' Christian Campos

* TheVoiceless: Wacky the Wolf never speaks and when Lexi impersonates Wacky, talking nearly blows her cover.

!!Violet
->'''Portrayed by:''' Claire Engler

* AbhorrentAdmirer: To Fletcher.
* CuteBruiser
* MusclesAreMeaningless: Violet easily takes down Officer Parks in "[=infANT=]".
* PintSizedPowerhouse
* UnstoppableRage

!!Zoltan Grundy
->'''Portrayed by:''' Dominic Burgess

* CloudCuckoolander: He tries to market phones to ''pets'' for one thing.
** And ''babies''. No, we're serious.
** Nonetheless, he is a genius in his own right.
* GoodCounterpart: To Principal Skidmore
* NoSocialSkills
* OddFriendship: With Lexi.

!!Hashimoto
->'''Portrayed by:''' Tom T. Choi

* ArchEnemy: To Zoltan Grundy and the [=ANTs=].
* AscendedExtra: Started out as one-shot character in ''Suite Life On Deck'', before becoming a main antagonist in ''A.N.T. Farm''.
* BadBoss: Using humans as guinea pigs? Check. Resorting to unpaid child labor? Check. Forcing his employees to sleep in tubes? Double Check.
* BigBad: Of Season 3
* CorruptCorporateExecutive
* TheRival: To Zoltan.
* TookALevelInJerkass: In SuiteLifeOnDeck, he was a fair and honorable HonestCorporateExecutive who's biggest flaw is he was very determined to make sure no one knew his secret recipes. Compare him to the now criminal and cold-hearted man he is in this show. Though, his StartOfDarkness began when Zoltan created the new [=ANT=] Farm, which led him to ruthlessly do whatever it takes to bring him down.
