!Dexter
[[quoteright:188:http://static.tvtropes.org/pmwiki/pub/images/188px-Dexter-dexters-laboratory-13130849-445-567_5461.jpg]]
->Voiced by: Creator/ChristineCavanaugh (seasons 1 and 2), Creator/CandiMilo (seasons 3 and 4), Creator/JeffBennett (his [[spoiler:FutureBadass]] self in Ego Trip)

* AmbiguousDisorder: Much like his sister. He has NoSocialSkills, a genius, and has trouble when basic concepts.
* AcCENTUponTheWrongSylLABle: "Dee-DEE, get out of my laBORatory!"
* TheAce: When it comes to science, of course. There was even an episode where one of his [[HotTeacher teachers]] [[TeacherStudentRomance clearly has the hots for him]].
* AdorablyPrecociousChild: Taken UpToEleven in fan-works.
* {{Adorkable}}
* [[AloofBigBrother Aloof Little Brother]]: To an extent.
* AnimalsHateHim: As seen in an episode when Dee-Dee tries to get him to play outside numerous times and animals constantly beat him up.
* BadassBeard and BaldOfAwesome: His future self.
* BadassBookworm
* BerserkButton: Mess with his sister, and you're dead meat.
* BigGood: In "Ego Trip".
** Also in any crossovers with other Cartoon Network franchises, he's either this or the de facto {{Leader}} including Cartoon Cartoon Fridays and FusionFall.
* ButtMonkey: Nothing goes right for this kid. ''Nothing''.
* ChildProdigy[=/=]InnocentProdigy: In one episode, he treats a burnt out light bulb as a kid would the death of a beloved pet.
* ChewToy
* ClockKing: Dexter once bought an expensive popsicle and paid with pennies. When the ice cream man asked Dexter how long it took him to count the pennies, Dexter correctly answered the question.
* CrouchingMoronHiddenBadass: Of a sort. Dexter tends to fail spectacularly at any form of physical activity, particularly sports... until the backdrop changes from "sports" to "Deedee let a giant monster out of the wormhole machine." Basically, he's an exaggerated stereotype of nerds are wimps up until science is involved. He can also go from ''deflecting lasers with his wrench like a Jedi'' to ''slap-fighting his rival'' and somehow manages to be in character both times. RuleOfFunny is involved, but still.
* DependingOnTheWriter: How smart he is can differ from episode to episode.
* DidNotThinkThisThrough: Tends not to consider the full ramifications of his inventions and schemes. For example, in "Morning Stretch", he used a time-slowing helmet to turn thirty seconds into thirty minutes, allowing him the time to get ready for school. He failed to realise that the slowed time would prevent him from properly taking a shower or making breakfast, and his homework ignited from friction burn when he tried to finish it.
* DitzyGenius
* EyeGlasses
* FieryRedhead
* TheFinickyOne
* FoolishSiblingResponsibleSibling: The responsible to Dee Dee's foolish.
* ForScience: CatchPhrase
* FutureLoser AND FutureBadass
* GadgeteerGenius
* GoodIsNotNice: He's an egotistical jerk, but undeniably a good person.
* GradeSkipper: Dexter once went to college. At first, all other students only wanted to party and he refused to join, despite their warnings about getting it out of the system. By the time Dexter proved them right by buckling under the strain, ''they'' were the ones who only wanted to study for the upcoming finals. His attempt to make a wild college party happen anyway got him expelled.
** In another episode, Dexter was considered for grade-skipping but needed to improve his P.E. grades. He cheated his way into victory and ended up becoming [[LaserGuidedKarma Dee Dee's yearmate]].
* HeightAngst: In "Ewww, That's Growth", Dexter and his family want to go on a really big rollercoaster, but Dexter is denied due to being too short. The resulting angst drives him to become as tall as possible, eventually allowing him to finally go on the rollercoaster by the end of the episode. [[spoiler:This backfires when he becomes so tall that he hits the ceiling at the very end.]]
* HerrDoktor
* IdenticalGrandson
* ImprobableWeaponUser: He's pretty handy with a wrench in matters of melee combat as well as mechanics.
* InsufferableGenius
* JerkWithAHeartOfGold
* LargeHam
* [[LikeFatherLikeSon Like Mother, Like Son]]
* MadScientist
* TheNapoleon
* NerdActionHero
* NerdGlasses
* NerdsLoveToughSchoolwork: Looks forward to hard tests.
* NoRespectGuy
* OmnidisciplinaryScientist: It may be easier to look for what areas of science Dexter HASN'T covered throughout the show.
* PingPongNaivete
* PrecociousCrush: On Lisa, the babysitter.
* RedHeadedHero
* SavvyGuyEnergeticGirl: Savvy Guy to Dee Dee's Energetic Girl.
* ScienceHero
* SensitiveGuyAndManlyMan: Sensitive Guy to his Father's Manly Man.
* ShorterMeansSmarter
* TheShortGuyWithGlasses: He's ''two feet tall''.
* SmallNameBigEgo: Became one in later seasons due to {{Flanderization}}.
* SmartPeopleKnowLatin: Or ''take'' it, anyway. In "Accent You Hate" he's shown opening his locker and saying "Good morning" to [[NerdsLoveToughSchoolwork his Latin and math textbooks]].
* TeachersPet: Although Mandark gives him some competition.
* TookALevelInBadass: In "Ego Trip".
* TVGenius
* UnexplainedAccent
** Possibly a meta-AuthorAvatar related reason: Tartakovsky was born in the Soviet Union and moved to the United States as a child. He [[CaptainObvious (most likely)]] has one as a child.
* WhatTheHellIsThatAccent: Dexter has a very peculiar accent that is either aiming for a stereotypical Eastern European accent, or a Bulgarian accent. Even Genndy Tartakovsky [[ShrugOfGod isn't certain what his accent is supposed to be.]]

!Dee Dee
[[quoteright:210:http://static.tvtropes.org/pmwiki/pub/images/098798789789_4403.JPG]]
->Voiced by: Alison Moore (Season 1 & 3), Kathryn Cressida (Season 2 & 4)

* AmbiguousDisorder: Sometimes has hints of this- she lacks a lot of social intuition, can't take a hint, seems to be very temperamental, and even her own ''friends'' get frustrated by her odd behavior at times.
* ActionGirl: When the situation calls for it.
* {{Adorkable}}
* AllGirlsLikePonies
* AnnoyingLaugh: It sounds like a horse's neighing, only high-pitched.
* [[AnnoyingYoungerSibling Annoying Older Sibling]]
* ArtEvolution: Had thick eyebrows and seemed to lack a chin in early episodes.
* BerserkButton: Mess with her brother, and you're dead meat.
** When Dexter wouldn't listen to her long-winded story about her day, she burst into tears and [[ItMakesSenseInContext turned into a giant monster and went on a rampage]].
* BewareTheNiceOnes / BewareTheSillyOnes
* CloudCuckooLander
* CrouchingMoronHiddenBadass
* TheCutie
* DeadpanSnarker
* DependingOnTheWriter: How nice or annoying she is varies from episode to episode.
** She also flip-flops from stupid to a StraightMan for Dexter.
* TheDitz
** GeniusDitz: She has her moments. She gave a [[GeniusBonus somewhat accurate description of Gregor Mendel]] in the Sasquatch episode.
* DreadfulMusician: She has an absolutely terrible singing voice. Doesn't stop her, though.
* DumbBlonde
* DumbIsGood
* FoolishSiblingResponsibleSibling: The foolish to Dexter's responsible.
* GenkiGirl
* GirlishPigtails
* GirlsLoveStuffedAnimals
* IdiotHoudini: Dee Dee always made a huge mess of Dexter's lab through her sheer idiocy and yet she never got any repercussion for it.
** Subverted in "Sdrawkcab".
*** Of course it's mostly because Dexter doesn't want to tell his parents his sister is trashing his SECRET LABORATORY that Dee Dee gets away with everything so it's pretty much Dexter's own fault.
* InnocentBlueEyes
* InnocentlyInsensitive
* KiddieKid
* KnightTemplarBigSister: Dee Dee may appear to be a flake, but you do NOT harm her little brother. Or she will kick your ass.
* {{Leitmotif}}: This whimsical, piano piece that plays when she shows up, usually when dancing.[[note]]Simulated [[https://www.youtube.com/watch?v=APRHE-Ri64g here]][[/note]]
* [[LikeFatherLikeSon Like Father, Like Daughter]]
* MotorMouth
* [[NiceGuy Nice Girl]]: She's pretty darn sweet and she absolutely ''adores'' her little brother. Her destructive tendencies are usually due to clumsiness or carelessness rather than malice, and sometimes it's shown that the reason she's always sneaking into Dexter's laboratory is because she just wants to spend time with her brother.
* NoIndoorVoice
* NoSenseOfPersonalSpace
* OlderThanSheLooks: The "Picture Day" episode implies she's in sixth grade. See KiddieKid.
* OnlyKnownByTheirNickname: Even her ''parents'' call her Dee-Dee.
** It's more a case of OneMarioLimit since "Dee Dee" is a actual name.
* NoIndoorVoice
* PinkMeansFeminine: Along with her two friends, who wear the same clothes as her.
* RepetitiveName
* SavvyGuyEnergeticGirl: Energetic Girl to Dexter's Savvy Guy.
* SpannerInTheWorks: ''Especially'' in Ego Trip, when she [[spoiler: wanders through the time portal at the end of the movie, goes "Oooh, what does this button do?", then pushes it and leaves.]]
* SweetTooth
* TomboyAndGirlyGirl: Girly Girl to her Mom's Tomboy.
* WalkingDisasterArea: At least whenever she's in Dexter or Mandark's lab. Or being abducted by aliens. Otherwise she manages to keep the property damage to a minimum.
* WhatDoesThisButtonDo: The TropeNamer.

![[spoiler: Susan]] "Mandark" Astronomonov
[[quoteright:143:http://static.tvtropes.org/pmwiki/pub/images/mandark_324252_2465.jpg]]
->Voiced by: Eddie Deezen

* {{Adorkable}}
* AlwaysSomeoneBetter: He was this to Dexter before VillainDecay kicked in.
* ArchEnemy
* AsianAndNerdy: Well half-Asian And Nerdy at least.
* BadBoss: His young adult self in TheMovie.
* BigBad: The closest this series has to one.
* BrainInAJar: His ultimate fate at the end of "Ego Trip."
* BreakoutVillain: Appeared infrequently in Seasons 1 and 2, became pretty much the 3rd main character by the time the show ended.
* CharacterizationMarchesOn: He had telepathy is his first appearance.
* ChildProdigy
* DarkIsEvil: His lab in post-finale seasons.
* DependingOnTheWriter: He's either a villainous mastermind or just some kid Dexter's rivals with.
* EmbarrassingFirstName: Retconned to [[spoiler: Susan]].
* EvilCounterpart: To Dexter; Tall and composed to Dexter's short and insecure. His younger sister, Olga "Lalavava" Astronomov, is this to Dee Dee, a short and solemn Technician to Dee Dee's tall and joyful Performer; while Dee Dee unwittingly destroys Dexter's creations but truly loves her brother, Lalavava bullies Mandark mercilessly.
* EvilGenius
* EvilLaugh: "HA haha! HA haha haha!" The fact that he cries, coughs and ''chews'' in the same way makes it border on being a VerbalTic.
* EyeGlasses
* FatBastard: In the third future of Ego Trip.
* {{Flanderization}}: Became more and more like a stereotypical EvilGenius as time went on.
** No kidding, he was just originally portrayed as Dexter's rival and at best, just wanted his lab shut down. Suddenly it went from that to trying to take over the world.
** To a lesser extent, his crush on Dee-Dee.
** Also, he didn't do freaking everything in the same rhythm as his EvilLaugh when he was first introduced.
* FreudianExcuse: His parents were people perpetually stuck in the 60's (i.e. hippies) and constantly stifled his scientific curiosity. He tried his best to go along with it, but one chance meeting with Dexter on the day he moved into the neighborhood ended with Dexter laughing in his face. Needless to say that was the straw that broke the camel's back.
** PlayedWith. He was hinted to have always been born with a negative disposition and his parents really didn't understand him though when they did realized they were denying some of his needs, they left their home and traveled around, eventually settling in Dexter's neighborhood.
* HarmlessVillain: After VillainDecay.
** NotSoHarmless: Though Ego Trip eventually proves he can still be a threat.
* HippieParents: Has this.
* HopelessSuitor: Is head-over-heels in love with Dee Dee, who is unaware... at best.
* InsufferableGenius
* LeanAndMean
* LightIsNotGood: Mandark's lab before post-finale seasons.
* MadScientist
* MeaningfulName: His vaguely Russian last name creates a [[EvilCounterpart parallel]] with Dexter's Eastern European Accent, [[spoiler: [[MeaningfulRename and his first name drives him to reject the New Age hippie lifestyle in favor of hard science.]] ]]
* MultipleChoicePast: He has two different origin stories.
* NerdGlasses
* OminousOperaCape
* RedAndBlackAndEvilAllOver: His alternate getup.
* TheRival
* SmugSnake
* TeachersPet: Competing for the role with Dexter.
* VillainousCrossdresser: Once Mandark replaced Dexter's mom. No one in the family noticed it, until the real mom came by.
* VillainousCrush: On Dee Dee.
* YoungerThanHeLooks: He's ([[VagueAge presumably]]) the same age as Dexter (though it's implied that Dexter has skipped at least one grade), but he's as tall as (if not taller than) Dee-Dee, and could easily pass for a teenager.

->Voiced by: JeffBennett

* HappilyMarried
* HartmanHips: The page image.
