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

* TheAce
* TheCastShowoff: She gets to sing at least once per episode. It's even [[LampshadedTrope lampshaded]] by Lexi in "chANTs of a lifetime".
-->'''Lexi:''' I spent $400 on tickets to see ''you'' sing? I see that every day for free!
* TheDanza: [[MyNaymeIs Sort of]].
* {{Expy}}: Of [[ThatsSoRaven Raven Baxter]], [[{{ICarly}} Carly Shay]], and [[{{Victorious}} Tori Vega]].
* FoolishSiblingResponsibleSibling: The Responsible to Cameron's Foolish.
* GenkiGirl
* HeterosexualLifePartners: With Olive.
* IdolSinger
* LittleMissSnarker
* NiceGirl
* PluckyGirl
* SassyBlackGirl

!!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.
* CatchPhrase: "What the heck?!" and "Interesting factoid".
* {{Cloudcuckoolander}}
* CunningLinguist
* CuteButCacophonic: Olive speaks relatively loudly and with an overdone accent of sorts.
* TheCutie
* 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 ''IntelligANTs''
** 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.
* {{Expy}}: Of [[HannahMontana Lilly Truscott]] and [[{{ICarly}} Sam Puckett]].
* GamerChick
* GenkiGirl
* HairOfGoldHeartOfGold: She's super smart, but more than a little naive. See InnocentProdigy.
* 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}}.
* LargeHam
* LittleMissSnarker
* MotorMouth
* NoIndoorVoice: Mostly in the first season, but it still shows up at times.
* [[OnlySaneMan Only Sane Woman]]
* {{Photographic Memory}}: Her talent, and what landed her in the A.N.T Farm to begin with.
* RapunzelHair
* TeenGenius

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

* {{Adorkable}}
* {{Book Dumb}}: Yet this did not prevent him from being in the ANT program
* {{Born Unlucky}}: He endures torment on a daily basis.
* {{Butt Monkey}}
* {{The Chew Toy}}: It's safe to say that Fletcher is the unluckiest ANT.
* {{Cloudcuckoolander}}
* {{Deadpan Snarker}}: He has his moments.
* {{Dogged Nice Guy}}: To Chyna.
* {{Expy}}: Of [[{{ICarly}} Freddie Benson]]. Though their personalities differ, as well as liking a specific subject (Freddie's Tech knowledge to Fletcher's Art).
* GeniusDitz: Fletcher's great at art, but thinks snow angels are dead snowmen.
* {{Genre Savvy}}
* {{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).
* StalkerWithACrush: To Chyna.

* OddFriendship: With Cameron.
* ScrewYourself: G-rated version of this at the end of "[=idANTity crisis=]".
* ShipTease: With Cameron.
