!The Class of 3000

!!Sunny Bridges
->'''Voiced by:''' [[Music/OutKast Andre 3000]]
''Like... You gotta crank this thang up!''

* TheAce
* ArtistDisillusionment: In-universe and at the start of the series as he no longer finds pleasure in being a musician (he outright walks out on a concert he was doing in Tokyo and promised them their money back). Lil D and his class re-ignite his passion for it, deciding that while he may be done in the music business, he still loves music.
* BerserkButton: He hates Santa Claus of all people. Due to Santa giving him a pair of ice skates instead of roller skates that got him injured, and lose the part in a Christmas pageant Sunny really wanted to be in.
* CoolTeacher: Admit it, you'd love to have him as your teacher.
* DealWithTheDevil: To get Li'l D out of his. [[spoiler: Then he acts so bad, explaining that he had no soul in his work, and thus gets his soul back and saves both of them from the devil.]]
* FourTemperamentEnsemble: Phlegmatic, being a calm, mature voice of reason.
* IJustWantToBeNormal: To an extent: While he got tired of the music business and being a star, he sill loves music and becomes a teacher, prefering the quietness it comes with it. In one episode,he almost quits when a hoard of celebrities try to teach at the school.
* InexplicablyAwesome
* InkSuitActor: Three guesses who he resembles.
* MagicalNegro
* TheMentor
* NiceHat: Nice straw hat, indeed.
* TeamDad: Especially seems this way to the fatherless Li'l D.
* UnclePennybags

!!Lil' D
->'''Voiced by:''' Small Fire
''Let's crank dis thang up!''

* AesopAmnesia: Suffers from this the most out of everyone in the main cast.
* BookDumb: Incredibly gifted when it comes to strategy and music... Regular school work, not so much.
* DisappearedDad: Mentioned in the pilot episode that he never met his father. He doesn't seem to mind, though.
** HeroicBastard: Possibly.
* FourTemperamentEnsemble: Choleric, being the somewhat rude and hot-headed leader.
* GuileHero: While his plans are questionable, they're usually effective.
* IJustWantToBeBadass: He wants exactly what Sunny has and is willing to take the quick way out.
* InSeriesNickname: Lil' D's real name is unknown.
* {{Jerkass}}: Downplayed. He's insensitive and self-interested, but doesn't mean any actual harm.
** TookALevelInKindness: At the end of the ChristmasEpisode. [[spoiler: It didn't last long. It's implied that he is back to his normal self by the end.]]
* TheLeader
* LoonyFan: Can be a little bit too obsessive for Sunny Bridges.
* TheNapoleon: Arguably.
* NiceHat: His skipper's cap, usually. (The pilot and ChristmasEpisode give him something else)
* NoodleIncident: Used as a joke twice. First to show how the class ''always'' gets into situations, and a second time to saw just how naughty he has that year.
* RedOni: To Phil's blue. Ironically he's the one with the cool color palette.

!!Madison Spaghettini Papadopoulus
->'''Voiced by:''' Creator/JenniferHale
* ButNotTooForeign: Her last name suggests she is of Greek descent, but she's also mentioned being part-Italian, part-Colombian, and [[RuleOfFunny part-Plutonian]].
* BrutalHonesty: A ditzy and insensitive variant.
-->'''Madison''': (To a giant upperclassman) Aren't there any jobs for first year students who think you guys are both- (If cut off by Kim putting her hand over her mouth)
* TheChick: One of two.
* CloudCuckoolander
* TheDitz
* DumbBlonde: Though she's beyond [[CloudCuckooLander just dumb]].
* [[Foil]]: She's this to her fellow string players.
** With Philly Phil, both characters have [[NoodlePeople tall and thin builds]], play stringed instruments, and have generally friendly and ditzy natures. However, while Madison plays the high-pitched violin and is a genuine DumbBlonde, Phil plays the low-pitched bass and is merely a DitzyGenius.
** With Tamika, both characters, again, play stringed instruments, and have very little in the way of a brain-to-mouth filter. However, while Madison is way more chipper and an optimist, Tamika is more cynical and realistic. This dynamic is best highlighted in "Take a Hike!"
* FourTemperamentEnsemble: Sanguine. She's chipper, friendly, and very positive.
* FriendToAllLivingThings
* GenkiGirl
* LiteralMinded: She sold her neighbour's garage at a garage sale once!
* NightmareFuelStationAttendant: Ghosty-Wosty anyone?
* PerpetualSmiler: So much.
* ThePollyanna

!!Phillip P. "Philly" Phil
->'''Voiced by:''' Creator/PhilLaMarr
* [[AlliterativeName Alliterative]] AND RepetitiveName: '''P'''hillip '''P'''hil.
* AmbiguouslyBi: While he's implied to have a crush on Kim and apparently got a girlfriend in "Free Philly", his HoYay moments hint that he may be bisexual.
* AmericanAccents: Philadelphia, at least in the early episodes.
* BigEater: With questionable tastes, like a pinecone covered in mud, or Sloppy Joes made with industrial waste.
* BlueOni: To Li'l D's red. Ironically he's the one with the warm color palette.
* DitzyGenius: For all his inventing smarts, he can be rather short-sighted.
** GeniusDitz: Like with Li'l D, it really [[DependingOnTheWriter depends on the episode.]]
* FieryRedhead: Inverted, as he's [[NiceGuy pretty chill.]]
* [[Foil]]: He's this to Kam and his fellow string players.
** With Kam, both characters are outsiders to Atlanta, more [[The Smart Guy intellectually-inclined]], and have more reserved personalities compared to the other kids, but while Phil is an optimistic NiceGuy who's more technologically-inclined, Kam is more [[JerkWithAHeartOfGold abrasive, cynical]] and more old-fashioned. Additionally, while Phil is the oldest kid, Kam is the youngest.
** With Madison, both characters are tall, play stringed instruments, and have generally sunny and ditzy natures. However, while Phil plays the low-pitched bass, is merely a DitzyGenius, and is [[NotSoStoic usually]] fairly reserved, Madison plays the high-pitched violin and cello, is a true [[TheDitz ditz]], and is way more open with her feelings.
** With Tamika, both characters play stringed instruments and prefer action to words. While Phil's bass usually played standing up, Tamika's harp is usually played sitting down. Phil is more likely to build a machine to solve a problem, while Tamika is more apt to apply force to it. Additionally, Phil's [[NoodlePeople tall and lanky build]] contrasts Tamika's short and stocky build.
* FourTemperamentEnsemble: Phlegmatic, though in a different way than Sunny. He's slightly submissive and one of the calmest kids.
** Dips somewhat into melancholic in Season 2.
* GadgeteerGenius
* GogglesDoNothing: Subverted. They're his glasses.
* HeroicSelfDeprecation: As revealed in Season 2, his self-esteem isn't all that great.
* MusclesAreMeaningless: Can lug a double bass around with no apparent strain, and [[BadassBookworm can stay on a biplane with nothing more than his bare hands at the most.]]
* NiceGuy: Very easygoing, if a little out there.
* NoSocialSkills: Even described as "socially challenged" in one of the promos!
* NoodlePeople: Has a very thin, tall body shape, giving off this trope.
* NotSoStoic: While Philly Phil generally keeps a level tone and inverts the usual [[FieryRedhead stereotype]] of redheads, he can be surprisingly emotional at times, which is always accompanied by his voice going up.
-->'''After calculating the blob will reach critical mass''': "There'll be no stoppin' the slop!"
* PungeonMaster: Likes terrible puns.
* TheSmartGuy: One of two. Specializing with various gadgets.


!!Edward "Eddie" Phillip James Lawrence III
->'''Voiced by:''' Creator/TomKenny
* AmazonChaser: Is smitten with the tough Tamika.
* DeadpanSnarker: Surprisingly, but Eddie can be pretty snarky.
-->'''Eddie''': (Upon seeing Li'l D's new wardrobe]] You look like a thrift store puked on you.
-->'''Li'l D''': Hey!
-->'''Eddie''': [[SarcasmMode Forgive me, that was rude. I meant to say "vomited."]]
* FictionFiveHundred: He's somehow rich enough to have ten fingers (as Philly Phil notes when he sees his own eight).
* FourTemperamentEnsemble: Melancholic. He's elegant, surprisingly good at doing physical work, and a bit moody.
* TheLancer: Acts as Li'l D's somewhat cowardly, but more sensible opposite.
* LonelyRichKid: Which becomes the subject for "Rich Shade of Blue".
* LovableCoward
** CowardlyLion: [[CrowningMomentOfAwesome Remember when he scared away that rabid dog, or when he was willing to be catapulted in to reclaim his role in the play?]]
* MasculineGirlFeminineBoy: Feminine Boy to Tamika's Masculine Girl.
* OverlyLongName
* PreppyName: It could get him mistaken for a king.
* ScrewTheRulesIHaveMoney (and sometimes ScrewTheMoneyIHaveRules)
* SpoiledSweet: He's rich enough to have a yacht as a gift. He's also a genuinely good dude who genuinely cares about his loved ones.
* StalkerWithACrush: Arguably.
* TeensAreShort: Is about 13 years old as of "Eddie's Money" and is one of the shortest characters.
* UnclePennybags
* UnrequitedLove: Towards Tamika.

!!Tamika Jones
->'''Voiced by:''' Crystal Scales
''Prove it or move it!''

* ActionGirl
* [[TheBigGuy The Big Girl]]: One of the tallest kids and by far the physically strongest.
* TheBully: Often likely to beat up the others.
* FourTemperamentEnsemble: Choleric, though in a different way than Li'l D, being the hot-headed no-nonsense member of the class.
* GrumpyBear
* HiddenDepths: Her house looks like something from Snow White and the only chores she's supposed to do is clean her room and do the lawn. The lawn is surprisingly clean and neat. We also see her rather kind-hearted father and it's implied she is somewhat embarrassed at how nice her folks are and where she lives.
* HypocriticalHeartwarming: Nobody bullies her friends except her!
* JerkWithAHeartOfGold: See HypocriticalHeartwarming above. Additionally, Tamika is more willing to help out than the other kids, such as defending Momo in "Funky Monkey."
* MasculineGirlFeminineBoy: Masculine Girl to Eddie's Feminine Boy.
* [[OnlySaneMan Only Sane Woman]]: Arguably the most normal and well-adjusted of the lot of them.
* SassyBlackWoman
* SkirtOverSlacks: Sort of, her leggings give off the vibe.
* TomboyishPonytail: More like "Tomboyish Bun", but same idea.
* TookALevelInKindness: In season 2.
* {{Tsundere}}: Is a Type A towards Eddie.
** Most of the ChristmasEpisode has her in full-blown "deredere" mode.

!!Kam Chin
->'''Voiced by:''' Creator/JaniceKawaye
* ButNotTooForeign: Stated to be born in Columbus, Ohio.
* ButtMonkey: The one who's always picked on.
** ChewToy: ... But we love him for it.
* DeadpanSnarker: Has shades of this.
* [[Foil]]: He's this to two characters.
** With Kim, his own twin. While both are amongst the more reasonable and logical characters, Kam is more serious and studious and is often said to have no imagination, contrasting Kim's sometimes scatterbrained and fun-loving personality.
** He's also this to Philly Phil. While both characters are outsiders to Atlanta, have more introverted personalities compared to their peers, and serve as [[TheSmartGuy the brains of the team]], Kam is far less [[JerkWithAHeartOfGold outwardly nice]] and focuses more on scholarly pursuits, contrasting Phil's NiceGuy personality and technological aptitude. Additionally, while Kam is the youngest kid, Phil is the oldest.
* FoolishSiblingResponsibleSibling: The Responsible to his sister's Foolish.
* FourTemperamentEnsemble: Melancholic, though in a different way than Eddie. He's very task-oriented, formal, and rigid.
* GoofyPrintUnderwear: As shown in "Mini Mentors" and "The Cure".
* InscrutableOriental: To an extent. When the other kids are hooting and hollering, he'll just be smiling.
* JerkWithAHeartOfGold: Snarky and at times rather rude? Definitely? Bad person? Definitely not.
* PolarOppositeTwins: Compared to his twin sister, he's more serious to his work.
* TheSmartGuy: One of two. More focused on academic work.
* ThoseTwoGuys: With Kim.
* ThroughTheEyesOfMadness: Played for laughs when he gets overheated in "Study Buddies".
* [[WhyDidItHaveToBeSnakes Why Did It Have to Be Hang-Gliding Through Ducks?]]: He has an irrational fear of this and has to survive it in order to save his classmates.

!!Kim Chin
->'''Voiced by:''' Creator/JaniceKawaye
* AsianAirhead: Has her moments in Season 2.
* ButNotTooForeign: Stated to be born in Columbus, Ohio.
* CatchPhrase: "I know, right?"
* TheChick: One of two.
* TheFashionista: She loves shopping and clothes.
* FashionableAsymmetry: As seen in "Tamika and the Beast", her socks are mismatched.
* FoolishSiblingResponsibleSibling: The Foolish for her brother's Responsible.
* FourTemperamentEnsemble: Sanguine, though in a different way than Madison. She's energetic, slightly scatterbrained, and positive.
* PolarOppositeTwins: Compared to her twin brother, she's more into clothing, shopping and arts.
* PinkMeansFeminine: Downplayed. While she's associated with the color pink, only a small part of her outfit is pink.
* ThoseTwoGuys: With Kam.
