->Voiced by: Creator/ChristineCavanaugh (First two seasons, ''WesternAnimation/EgoTrip'', and first five episodes of Season 3), Creator/CandiMilo (Remainder of Season 3 and Season 4), Creator/JeffBennett (his [[spoiler:FutureBadass]] self in ''Ego Trip'' and his superhero self in "Comic Relief")

* 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}}: Oh yes. He's a very brainy child whose awkward and shy personality is loved by the fans.
* AlwaysSomeoneBetter: Proves to be this to Mandark, especially by end of the latter's first appearance. Best shown in "Mandarker" where the two compete in a science fair. Mandark is an inconsolable mess still hung up on his destroyed lab and has to resort to supernatural methods because he can't come up with anything on his own while Dexter effortlessly impresses the judges with one of his "scribbles" and has moved on from being forced to shut down his lab.
* AnimalsHateHim: As seen in an episode when Dee-Dee tries to get him to play outside numerous times and animals constantly beat him up. At the end of the episode, when Dexter is finally able to relax outside, several animals, including ''[[UpToEleven a fish]]'', jump out of nowhere onto Dexter in a BigBallOfViolence.
* AsideGlance: Has done these on occasions whenever he's annoyed by someone (usually Dee-Dee).
* BadassBeard and BaldOfAwesome: One of his future selves in ''Ego Trip'' is very muscular, has a beard, and is bald.
* BadassBookworm: He is a tiny, stub-limbed boy genius who spends all his time in his secret laboratory, trying in vain to keep his pretty-princess {{Cloudcuckoolander}} sister out. Until a monster attacks the city, or aliens invade, or a meteor threatens Earth; then Dexter pulls out one of his giant, anime-inspired robots, super-powered exoskeleton suits, or space ships and kicks ass. He also seems to have learned kung-fu at some point.
* BerserkButton: Do not enter his lab.
* BigBrotherInstinct: Or little brother, in this case. 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''.
* CainAndAbel: Usually the prickly Abel to Dee Dee's oblivious Cain, but Dexter falls squarely into the former category when he and his future selves create a quintet of mechanized assassins to kill his sister as punishment for [[spoiler:saving human civilization when he was just inches away from doing so himself.]]
* CatchPhrase: "Dee Dee get out of my [[AcCENTUponTheWrongSylLABle lab-OR-a-tory!"]]
* TheChewToy: He suffers this greatly in alot of crazy forms. For example, his entire lab is completely destroyed, the earth is destroyed, Dexter is turned into a sandwich, etc. He also gets into big trouble from his mom and dad as well. Especially his backbone-lacking teenage/young adult self in "Ego Trip", who works for Mandark designing cubicles in the future.
* ChildProdigy: In one episode, he treats a burnt out light bulb as a kid would the death of a beloved pet.
* 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.
* DeadpanSnarker: Especially in his interactions with Dee Dee.
* DependingOnTheWriter: How smart he is can differ from episode to episode.
* DidntThinkThisThrough: Tends not to consider the full ramifications of his inventions and schemes.
** 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 realize that the slowed time would prevent him from properly taking a shower or making breakfast, and his homework ignited from FrictionBurn when he tried to finish it.
** In "The Continuum of Cartoon Fools", he gets so desperate to keep Dee Dee out of his laboratory for good that he destroys all the secret entrances and locks the front door, realizing too late that this would keep even himself from entering the lab.
** In "Comic Stripper," when he realizes that Mandark is getting his latest {{Evil Plan}}s from the comic book ''Mister Misery'', he buys every copy of the next book in an effort to beat Mandark at his own game, expecting him to do the same. However, Dexter is caught unprepared when Mandark instead copies the comic book ''Dangerous Duck''. It didn't occur to Dexter that since he bought all of the copies of ''Mister Misery'', Mandark wouldn't be able to get the new issue and copy Mister Misery's moves; Mandark even lampshades it.
* DitzyGenius: He's able to time-travel, create robots and build portals to other dimensions, but is utterly incapable of taking care of himself for a single day when his mom is sick. He doesn't know how to cook (having never heard of "flour"), and as for cleaning... Also why would he put buttons and triggers in places Dee-Dee would obviously activates. In general, what he has in scientific smarts, he lacks in common sense.
* EarnYourHappyEnding: It takes a lot of hardship and more than a few decades, but Dexter's genius eventually makes the world a better (and smarter) place as Ego Trip shows.
* EmperorScientist: He grows up to be an incredibly benevolent, if scatterbrained, elderly inventor who presides over a sublime {{Utopia}}.
* EnragedByIdiocy: Is easily angered by Dee-Dee's ditzy behavior.
* ExtremeDoormat: His early 20's self in ''Ego Trip'' is this to Mandark.
* EyeGlasses: The glasses can change shape depending on expression.
* FatalFlaw: Dexter has three that are almost always his downfall:
** His temper. Dexter proves able to handle Dee Dee effortlessly when he takes a moment to think but he has a HairTriggerTemper that makes him default to impulsive action when it gets set off.
** His pride. Dexter has a very high opinion of himself, disproportionate to his actual competence, which has caused him some major issues. Dee Dee can manipulate him into doing things by implying he isn't as smart as he holds himself to be and if he believes that someone is his superior in ways to deems meaningful then it tends to break Dexter. '''Badly.'''
** His devotion to science. He will sometimes employ convoluted scientific methods to achieve his goals, often overlooking more simple solutions that would be unlikely to blow up in his face.
* FieryRedhead: His family is split evenly between this and the DumbBlonde stereotype; he and his mother are fiery redheads and his sister and dad are happy-go-lucky yellow-haired ditzes.
%%* TheFinickyOne
* FoolishSiblingResponsibleSibling: The Responsible to Dee Dee's Foolish.
* ForScience: His CatchPhrase.
* FutureBadass: Invoked in the MadeForTVMovie, ''Ego Trip'', wherein Dexter travels to the future for the primary purpose of seeing what kind of badass he is. In the dystopian future version of himself, he comes to resemble his hero Action Hank: big, brawny, and [[BadassBeard bearded]] (and unlike Hank, [[BaldOfAwesome he goes bald]]), and his MadScientist pseudo-Germanic accent is replaced by an Arnold impression.
* FutureLoser: This trope is also averted in Dexter's other two future versions, a wimpy office drone and a hilarious old man. The FutureBadass version of Dexter exists between the two chronologically. However, we eventually see the former [[TookALevelInBadass take a level in badass]].
* GadgeteerGenius: Dexter created a lot of stuff in the series.
* 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: Dexter is a MadScientist with a German accent made more blatant (and funny) since none of his family has any accent or gives any indication they have any German ancestry
* IdenticalGrandson: He's a younger version of his grandfather.
* IdiotHero: He can time travel and build an underground lab miles long but will go through hell and back to buy ice cream that he could easily make at home.
* ImprobableWeaponUser: He's pretty handy with a wrench in matters of melee combat as well as mechanics.
* InnocentProdigy: In one episode he sees a repair-man working on the house's electrical system, and after some failed attempts to find out what he's up to using technology, Dexter's Plan C turns out to be to run off to "mommy" and ask her who's the strange man messing around with the fuse box.
* InsufferableGenius: He can be very arrogant when it comes to his smarts.
* JerkWithAHeartOfGold: He's not a bad person, but he can be quite rude and egotistical.
* LargeHam: He can be quite expressive and loud, especially when he yells at his sister to get out of his laboratory or is gloating about his latest scientific achievement.
* LikeParentLikeChild: He's a FieryRedhead like his mother. She is also the source of his pride and creative impulses.
* MadScientist: Not villainous example, obviously. The premise of the show is that Dexter is a kid mad scientist with a secret laboratory.
* ManChild: Teenager Dexter from "Babysitter Blues" and Old Dexter from "Old Man Dexter" could be excused on the grounds that both circumstances had Dexter accelerate his age to woo his sitter and watch the late night movie with his family respectively, but FutureBadass Dexter cements it by whining he should've been the one to save the future and goes on with the plan of creating robots to destroy Dee Dee.
* NakedPeopleAreFunny: Frequently seen nude, be it in the shower or by complete accident.
* TheNapoleon: He has the short stature and the attitude.
* {{Narcissist}}: He has a ''very'' high opinion of himself. Case in point: in "The Parrot Trap," he built a robotic parrot purely so he could hear it repeat his own self-indulgent praises.
* NerdActionHero: He has his moments in the show, being a super scientist with an assortment of cool robots and gadgets, but it really becomes true for his FutureBadass version seen in ''Ego Trip''.
* NerdGlasses: He has thick framed glasses that double as EyeGlasses.
* NerdsLoveToughSchoolwork: Looks forward to hard tests.
* NoRespectGuy: He's SurroundedByIdiots and hardly gets any respect.
* OmnidisciplinaryScientist: It may be easier to look for what areas of science Dexter HASN'T covered throughout the show.
* PingPongNaivete: He had his moments of stupidity. One example is when he thought he was going to die...because he had gas. We're talking about a boy genius that has done everything from go inside his sister's body to traveling to other planets using his inventions. To "simulate" the gas buildup in his lab, he used a balloon to represent himself. In other episodes/shorts, he didn't know what the "strange protrusions" all over his body were (he had the chicken pox) and tried to do a search through the entire animal kingdom for the "species" known as... the girl.
* PrecociousCrush: On Lisa, the babysitter.
* RidiculouslySuccessfulFutureSelf: His future self is the ruler of a utopia.
* SavvyGuyEnergeticGirl: Savvy Guy to Dee Dee's Energetic Girl.
* ScienceHero: He is a ChildProdigy who owns a huge underground laboratory.
* SensitiveGuyAndManlyMan: Sensitive Guy to his Father's Manly Man.
* ShorterMeansSmarter: Not so much when paired with his much taller rival Mandark, but definitely when paired with his taller sister Dee Dee.
* 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]].
* SwissCheeseSecurity: No matter what measures he takes, Dee Dee ''always'' manages to slip into his laboratory without any trouble.
* TeachersPet: Although Mandark gives him some competition.
* ThrowTheDogABone: Ego Trip, as the title implies, is basically an entire movie of Dexter finding out that all his efforts pay off...eventually.
* TookALevelInBadass: In "Ego Trip". Teenage Dexter is portrayed as a complete wuss. [[BerserkButton Until Madark breaks his glasses.]]
* TVGenius: He's a world renowned genius capable of building time machines, giant robots and create all sort of genetically modified creatures, yet thinks "girl" is some kind of tribe, doesn't know what dirt is, and one time thought he was going to die due to having gas.
* 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.
* TheUnfavourite: His parents usually love him and his sister Dee Dee equally, but one notable instance of this trope is in "Oh, Brother", where Dexter turning his sister Dee Dee into a brother named Doo Dee resulted in Doo Dee getting all the attention while Mom and Dad ignored Dexter.
* 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.]]
* WorldHealingWave: The purpose of the Neurotomic Protocore is to send out such a phenomenon which would boost the joint intellect of mankind to superhuman levels, eliminating ignorance and promoting universal peace & brotherhood. It can also do the exact opposite, sucking in the intelligence of human beings worldwide to solely enrich the mind of its user, which is why Mandark wanted it so bad. However, while Dexter was able to create the core itself when he was just a child, it would be decades until he or Mandark would find a way to actually tap into its power.

[[folder: 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), Creator/KevinMichaelRichardson (deepened voice in "Dee Dee Be Deep"), Pamela Adlon (gender-bent self Doo Dee in "Oh, Brother")

* AccidentalHero: [[spoiler: At the end of ''Ego Trip'' when she pressed the button that reversed the effects of the neurotomic protocore that Mandark used to make everyone idiots, much to the ire of the Dexters.]]
* 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.
* AllGirlsLikePonies: She is a pony fancier, as are her cloney best friends. There was the episode where she asked Dexter to turn her into a pony because she liked the My Little Pony expy so much.
* AnnoyingLaugh: It sounds like a horse's neighing, only high-pitched.
* AnnoyingYoungerSibling: Actually an "Annoying ''Older'' Sibling" to Dexter, constantly breaking his stuff among other things.
* BerserkButton:
** When Dexter wouldn't listen to her long-winded story about her day, she burst into tears, [[ItMakesSenseInContext turned into a giant monster and went on a rampage]].
** She gets furious when Dexter uses one of her dolls as an experiment.
* BewareTheNiceOnes: Dee Dee is quite a force to be reckoned with if angered.
* BewareTheSillyOnes: God help you if you make Dee Dee seriously angry.
* BigSisterBully: Her treatment of Dexter has shades of this at times. In one episode, she stole Dexter's money right out of his hands to buy something, and when Dexter asks why she did so, she tells him point-blank, "You're so small and weak that I ''could''!"
* BigSisterInstinct: Mess with her brother, and you're dead meat.
* {{CloudcuckooLander}}: She is born in Cuckooland. It is especially evident when she tells Dexter her bedtime story while she's sick, mixing a variety of common childhood nursery rhymes and stories.
* CrouchingMoronHiddenBadass: While Dee Dee is very ditsy, she's actually capable of taking on serious threats that Dexter is too weak to fight without his inventions.
* TheCuckoolanderWasRight: In "Chicken Scratch", she is shown to be right about scratching chicken pox causing one to turn into an evil contaminated chicken.
* TheCutie: A bubbly, ditzy, lovable little girl who wears pink.
* DeadpanSnarker: When she's not being a ditz, tends to snark.
* DependingOnTheWriter:
** Gets hit with this pretty bad. How nice or annoying she is varies wildly from episode to episode. In some episodes, she's rather innocent and her destructive tendencies are accidental and due to playful clumsiness. In others, she's far more malicious and intentionally antagonistic.
** She flip-flops from stupid to a StraightMan for Dexter.
* TheDitz: The trope namer for "WhatDoesThisButtonDo". She often annoys Dexter because of her idiocy.
* DoesNotLikeShoes: She spent nearly the entirety of "Sassy Come Home" proudly running around barefoot after she took off her "goshforsaken boots", which attracted a new playmate- Sasquatch.
** Slightly related- she got frustrated by a bunch of shoe gnomes who all tried to immortalize her feet when she bared them in the act of trying on their shoes.
** She also stomped an oversized amount of laundry into a washing machine shoeless.
* DreadfulMusician: She has an absolutely terrible singing voice. Doesn't stop her, though.
* DumbBlonde: A mix of this and {{CloudcuckooLander}}...though she has her moments.
* DumbIsGood: Much more cheerful and pleasant than Dexter.
* EarlyInstallmentCharacterDesignDifference: Had thick eyebrows and seemed to lack a chin in early episodes.
* FoolishSiblingResponsibleSibling: The Foolish to Dexter's Responsible.
* GeniusDitz:
** She gives a [[GeniusBonus somewhat accurate description of Gregor Mendel]] in the Sasquatch episode. She can break through any security measure Dexter comes up with. When she's not wrecking them, can use Dexter's inventions with instant mastery, like a hovercraft Dexter himself crashed or an incredibly complicated giant mech.
** A subtle moment from the show's opening titles implies that Dee Dee is smarter than she lets on: Dexter frantically presses a button, attempting to turn on a large light, then Dee Dee briefly gives Dexter an aside glance and coy smile and plugs a cord into a nearby socket, successfully turning on the light.
* GenkiGirl: She's an extremely energetic, hyperactive girl.
* GirlishPigtails: Blonde pigtails.
* GirlsLoveStuffedAnimals: She loves her dolls.
* GirlyGirlWithATomboyStreak: Sure, she likes playing with dolls and ballet, but she also likes video games, sports and rollerskating.
* HypocriticalHumor: Whenever Dee Dee meets someone of her own clingy and destructive level, she finds them intolerable and inconsiderate. For example, in the pilot episode, when she finds out that Dexter broke into her room to steal one of her dolls for experiments, she completely loses it and confronts him, while ignoring the fact that she regularly breaks into his lab uninvited and destroys it without a care for Dexter's feelings.
** Then we have [[ParodyEpisode Dollhouse Drama]], in which she steals one of ''his'' miniatures, brings it back to ''her'' room, and plays with it.
* IdiotHoudini: Dee Dee always made a huge mess of Dexter's lab through her sheer idiocy, sometimes even causing quite a lot of destruction among others as well, yet she almost never got any repercussion for it. Seasons 3 and 4 were a little better about averting this. Partly because there were fewer episodes that had Dee Dee in the lab but she was a lot more prone to actually getting called out for her antics. It helps that there were times that she actually did try to clean up the messes she made and that she either went down with Dexter or suffered as a result of her own actions.
* InnocentBlueEyes: She has blue eyes and is definitely naive.
* InnocentlyInsensitive: Dee Dee is usually just a playful GenkiGirl who wants to play with her little brother. However her notions of fun include playing around with his pretty looking (and somewhat delicate) toys, and no amount of ranting at her to leave him alone ever seems to faze her.
* KarmaHoudiniWarranty: There ''are'' episodes where she gets her comeuppance.
* KiddieKid: Dee Dee is elder to her titular brother, and the "Picture Day" episode implies that she is in the sixth grade. This would put Dee Dee's actual age somewhere between ten and twelve, but she tends to behave as if she were younger than Dexter.
* 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]]
* LethallyStupid: She usually sabotages Dexter's experiments and destroys his lab, although she does so out of ignorant curiosity rather than malicious intent.
* LikeParentLikeChild: Her dad is where she gets her lack of foresight and curiosity.
* LyingFingerCross: In comic book story "Salt and Pepper", Dexter and Dee Dee make a deal where she'll stay away from his lab forever. When he tries to collect, she reveals that she crossed her fingers.
* MotorMouth: She quite often speaks very rapidly, just barely able to be coherent without speaking slowly.
* NiceGirl: 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: She frequently yells at the top of her lungs.
* NoSenseOfPersonalSpace: Pretty much the defining premise of Dee Dee's character. It's rare for her to leave her brother alone.
* ObliviousToLove: Mandark is in love with her but she seems unaware of it.
* OnlyKnownByTheirNickname: Even her ''parents'' call her Dee-Dee. It's more a case of OneMarioLimit since "Dee Dee" is an actual name.
* PersonOfMassDestruction: Every time Dee Dee manages to get into Dexter's lab, she almost always leaves a massive amount of destroyed machinery and inventions in her wake. In Mandark's debut episode, Dexter even [[ExploitedTrope used this to his advantage]] to get back at Mandark.
* PetTheDog: She may constantly be wrecking Dexter's stuff and annoying him to no end, but it is shown on more than one occasion that she actually does care about her younger brother.
* PinkMeansFeminine: Along with her two friends, who wear the same clothes as her.
* RepetitiveName: Dee Dee.
* 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: She loves candy.
* UnsportsmanlikeGloating: Whenever she beats Dexter in a game, she will always taunt him for it. In "Game Over", for example, every time Dee Dee beats Dexter at video games, she relentlessly rubs it in his face, dancing around the room and chanting "I won!". And when Dexter tells her he doesn't want to play with her anymore, she calls him a SoreLoser.
* 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. Dee Dee elevated this to an art form, as this would usually be the last thing Dexter would hear before one of his inventions [[HoistByHisOwnPetard goes awry.]] She sort of Lampshaded it in the episode where Dexter's trying to sleep:
-->'''[=Dee Dee=]:''' I went into your lab... and, I pushed this button...\\
'''Dexter:''' Oh, just like the last ''thousand'' times?\\
'''[=Dee Dee=]:''' I think it's really serious this time... ''(cut to self-destruct device counting down)''

[[folder: Dad]]
[[quoteright:212:http://static.tvtropes.org/pmwiki/pub/images/9878768_3313.JPG]]
->Voiced by: Creator/JeffBennett

* AbusiveParents: Downplayed, as he isn't horribly abusive, but as shown in several episodes, such as "Better off Wet," Dexter's dad can be a bully, embarrassing and pulling childish pranks on his family for his own enjoyment. These often include pushing his family in the pool, and very manipulative behavior.
* {{Amazingly Embarrassing Parent| s}}: Has a tendency to humiliate his kids on accident.
* ArtEvolution: His appearance after the reboot had him a lot skinnier.
* BerserkButton: You can threaten him, you can break his car and he'll just brush it off. But don't ''ever'' not-hold a door open for a lady--ESPECIALLY his wife!
* BewareTheNiceOnes: ''Hoo boy'' - there's his ManipulativeBastard tendancies, for a start. Then there's the times he gets ''really'' mad...
* BumblingDad: Both parents are bumbling, though their primary flaw was being clueless to Dexter's Laboratory (and he has a memory erasing gun, so its more like they look stupid by comparison to their supergenius son.) Dexter's father turns out to be a stunt biker when his job is finally revealed (up to then, he left every day dressed for an office job), making him much cooler and more competent than the typical example.
* CrouchingMoronHiddenBadass: And when it happens, ''watch out.''
* DumbBlonde: Subverted - while he's clearly not as smart as Dexter, he possesses average intelligence, and has moments of genius.
* EyeGlasses: Like Dexter's glasses, they can change shape depending on expression.
* {{Flanderization}}: Became a SmallNameBigEgo in the later episodes
* GeniusDitz: He's generally pretty care free and goofy, but he can be surprisingly crafty and manipulative when he wants to, bordering on TheChessmaster. If mom's muffins are involved, ''watch out!''
* HappilyMarried: To Dexter's Mom.
* JerkWithAHeartOfGold: While he tends to pull petty pranks on his family, he does care for them.
* JockDadNerdSon: He's the Jock Dad to Dexter's Nerd Son.
* ManChild: As seen above, he can be very childish and immature.
* ManipulativeBastard: He's this when he wants to be in "The Muffin King" and "Snowdown".
* NoNameGiven: His first name is unknown.
* PapaWolf: He'll go through all sorts of danger if his kids are in trouble.
* SanitySlippage: In "The Muffin King", he gets so upset over his children preventing him from eating one of Mom's muffins too early that he ends up having a fantasy about ruling over a land inhabited by sentient muffins.
* StandardFiftiesFather: He walks a fine line between this and the BumblingDad.
* TookALevelInBadass: Dexter's dad goes from average middle class guy and sports enthusiast to daredevil stuntman in one episode of the later seasons.
* TookALevelInDumbass: By the fourth season, he's become a complete nitwit. For instance, he doesn't know that he is being threatened legal action for stealing cable in "Bad Cable Manners" in spite of being repeatedly told so by the authorities that warn him and in "Tee Party" is shown to have no idea how golf works even though he was shown to be a fan of the sport in "Dad is Disturbed".
* UnnamedParent: He is only called ''Dad''.
[[/folder]]

[[folder: Mom]]
[[quoteright:218:http://static.tvtropes.org/pmwiki/pub/images/09890898_6165.JPG]]
->Voiced by: Creator/KathSoucie

* ActionMom: Demonstrated in "Mom and Jerry", "World's Greatest Mom" and "A Mom Cartoon".
* {{Amazingly Embarrassing Parent| s}}: Most notably in the episode "Chess Mom", where she embarrasses her son while trying to cheer him on at the chess tournament.
* AmbiguousDisorder: Her obsession with cleanliness goes beyond what is healthy.
* BerserkButton:
** As seen in "Dexter's Rude Removal", the most Mom ever got beyond angry was when the rude clones of Dexter and Deedee not only made a huge mess of her kitchen during a food fight but used profanity as well.
** Germs, period.
* BewareTheNiceOnes: Whenever her BerserkButton is pushed, or her children are threatened.
* CuteBruiser: Dexter's mother has shown to be able to fight very well.
* FieryRedhead: The family is split evenly between this and the DumbBlonde stereotype; Dexter and his mother are fiery redheads, his sister and dad are happy-go-lucky yellow-haired ditzes.
* {{Flanderization}}: Her NeatFreak tendencies get played up considerably in the later episodes.
* GeniusDitz: Similarly to Dexter's dad. She shows frightening proficiency with technology when it comes to battling germs.
* GoodParents: Despite her faults, she's a genuinely loving Mom towards both Dexter and Dee Dee.
* HappilyMarried: To Dexter's Dad.
* HartmanHips: The page image. In fact, when Dee Dee gets turned into a duplicate of Mom in one episode, she feels her hips with awe.
* {{Housewife}}: She seemed to have little characterization outside of her housework, though it's been implied a few times that she was a lot more rebellious in her youth. Her typical outfit that she wore everywhere even included yellow rubber dishwashing gloves and an apron.
* IconicItem: Her yellow rubber gloves. So much so that she feels naked without them.
* MaleGaze: Cameras don't hesitate to get as many shots from the back as they can. "Better Off Wet" in particular features her in a bikini.
* MamaBear: Best shown in "Go, Dexter Family! Go!", where hearing her son cry for help motivates her into breaking free from her bonds and kicking the aliens' asses.
* MistakenForBadass: She once "defeated" the reigning snowball champion (Dexter's dad) by playfully chucking a snowball at him. He's been convinced ever since that she has evil snowball powers, which she passed on to Dee-Dee.
* NeatFreak: The episode "Pslyghtly Psycho" suggests that she is actually germophobic, particularly when her gloves and slippers are removed and she finds herself afraid to even set foot on the carpet barefoot.
* NoNameGiven: Her first name is unknown, although her maiden name is probably "O'Reilly," as seen in one episode that features her brother.
* RedheadInGreen: She wears a pale green blouse-shirt with a wide collar, white apron and dark green pants. Also her bikini is green.
* SkewedPriorities: She favors cleanliness over anything. One episode has her ignoring the fact Dexter had destroyed her entire house over the fact he was clean.
* UnnamedParent: She is only called ''Mom''.

[[folder: Mandark]]
[[quoteright:143:http://static.tvtropes.org/pmwiki/pub/images/mandark_324252_2465.jpg]]
->Voiced by: Eddie Deezen

* AffablyEvil: He usually uses his manners, and has some VillainRespect for Dexter.
* AlwaysSomeoneBetter: He was this to Dexter before VillainDecay kicked in.
* ArchEnemy: Dexter's rival.
* AsianAndNerdy: He's half-Asian and a genius.
* BadassBookworm: It should be expected as he's Dexter's EvilCounterpart.
* BadassCape: Gets one in ''Ego Trip'' and the later seasons.
* BadBoss: His young adult self in TheMovie, who punishes one of his employees (Dexter) for almost being late by lashing him in front of the other workers.
* BaldOfEvil: His future self from the time of Dexter's FutureBadass self has no hair on his head and has taken over the world by using the neurotomic protocore to make everyone else dumb.
* BigBad: His appearances weren't as frequent in the first two seasons, but he is unquestionably the main villain in ''Ego Trip'' and the final two seasons.
* 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, an ability that was never brought up again.
* ChildProdigy: A boy Genius like Dexter.
* CorruptCorporateExecutive: His youngest future self in ''Ego Trip'', who eventually took control of the company he and Dexter worked for and started using its resources to advance his plans for world domination.
* DarkIsEvil: His lab in post-finale seasons. Also, of course, his [[DarknessVonGothickname nickname]].
* DarknessVonGothickname: His preferred, self-given alias.
* DependingOnTheWriter: He's either a villainous mastermind or just some kid Dexter's rivals with.
* DudeLooksLikeALady: The reason why he got his first name as a little child. His parents were apparently incapable of recognizing the difference between male and female and treated him and dressed him like a girl, which makes one wonder if they even had a doctor to tell them the distinction after he was born- or if he was even born in a hospital. This no longer applies now that he's older.
* EmbarrassingFirstName: Retconned to [[spoiler: Susan]].
* EntitledBastard: In his debut episode, he genuinely expects Dexter to help set him up on a date with Dee Dee, despite the fact that he had spent the entire episode one-upping Dexter and forced him to shut down his lab; Dexter only goes along with it because he realizes he can exploit Dee Dee's [[WalkingDisasterArea destructive tendencies]] to have Mandark's own lab shut down.
* EvenEvilHasStandards: After a day posing as Dexter's mother, he is left so exasperated from spending a day in her shoes (and ceaselessly tending to every single trivial problem the other family members whine over) he aborts the plan, yelling the family are nothing more than selfish creeps.
* 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. His parents also serve as not so evil counterparts to Dexter's, being a pair of 60's era hippies in contrast to Dexter's straight laced 50's inspired ones.
* EvilGenius: His talents and competence are equal to Dexter's.
* EvilLaugh: "[[https://youtu.be/gh6E1HZvLxY?t=5s HA haha! HA haha haha!]]" The fact that he cries, coughs and ''chews'' in the same way makes it border on being a VerbalTic.
* ExpositoryHairstyleChange: He was once long-haired, then got his iconic bowl cut when he decided to reinvent himself into Mandark, and those two bangs in the middle are the result of using a cracked bowl as his template, which fittingly form a meaningful "M" for Mandark similar to the way Creator/MattGroening hid his initials in [[WesternAnimation/TheSimpsons Homer Simpson's]] design as an easter egg.
* EyeGlasses: Much like Dexter, his glasses change shape to match his emotions.
* FatBastard: In the third future of Ego Trip, he is extremely obese and has to have a hook and later a robot carry him around. The official Cartoon Network Website nicknamed him "Fat Cat Mandark" back in the days it was still featuring digital collectibles that you could buy and trade these items from obtaining credits from playing games and being active on the website.
* {{Flanderization}}: Became more and more like a stereotypical EvilGenius as time went on. 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.
* 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.
* GenderBlenderName: His real name is [[spoiler:Susan]]. He's very ashamed of it, too.
* HarmlessVillain: After VillainDecay.
* HippieParents: Turns out Mandark's parents are hippies, and his real name is [[spoiler:Susan]], because they originally thought he was a girl. They didn't bother to change it because they were fond of it even in spite of the fact they had a boy, so he did for them.
* HopelessSuitor: Is head-over-heels in love with Dee Dee, who is unaware... at best.
* InsufferableGenius: His ego is comparable to Dexter's.
* {{Jerkass}}: He makes Dexter's life miserable simply because he believes he's better than him.
* KnightOfCerebus: His villainy is taken much more seriously in "Ego Trip", since it is shown in the future that he has taken over the world and made everyone stupid just because he didn't want to share his knowledge with anyone else. Because of this, the future is shown to be a complete CrapsackWorld.
* LeanAndMean: He's a skinny EvilGenius.
* LightIsNotGood: Mandark's lab before post-finale seasons.
* MadScientist: An evil boy mad scientist with EvilLaugh and all.
* 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.]]]] His Russian sounding last name Astromonov also serves as a shout out to the series creator being a Jew from Russia. It's implied his father may be of Russian and perhaps Jewish descent to parallel Genndy Tartakovsky while his Asian mom parallels Yoko Ono.
* MultipleChoicePast: He has two different origin stories.
* NerdGlasses: He wears thick framed EyeGlasses like Dexter.
* NotSoHarmlessVillain: Ego Trip eventually proves he can still be a threat, even after his VillainDecay.
* OminousOperaCape: Wears a long black cape in his alternate getup.
* OnlyKnownByTheirNickname: His real name is [[spoiler:Susan]].
* PetTheDog: When he's actually siding with Dexter or just taking a break from evil in general.
* RedAndBlackAndEvilAllOver: His alternate getup is a costume colored red and black.
* TheRival: Dexter's nemesis and rival boy-Genius.
* SmugSnake: He's often portrayed as condescending towards Dexter.
* TeachersPet: Competing for the role with Dexter.
* TookALevelInJerkass: In the revival seasons, Mandark becomes significantly more evil, becoming Dexter's enemy rather than his rival.
* VagueAge: It is difficult to tell if Mandark is actually elder to Dexter, or if he is the same age as him but just appears older. On one hand, Mandark is in the same class as Dexter, and is generally treated as his equal. On the other hand, Mandark has a younger sister, and Dexter is implied to be a GradeSkipper. Further confusing matters is Mandark's obsession with Dee Dee, who is older than Dexter and is suggested to be a sixth grader, which would make her a tweenager.
* VillainDecay: When Mandark was introduced first, he was portrayed as being much smarter than Dexter, and his lab was (And still is) even bigger and more impressive than Dexter's; however, after Dee Dee destroyed his lab, Mandark [[AlwaysSomeoneBetter fell to second place,]] [[CantCatchUp and is no longer]] Dexter's equal.
* VillainousCrossdresser: Once Mandark replaced Dexter's mom. No one in the family noticed it, until the real mom came by.
* VillainousCrush: He has an unrequited crush on Dee Dee.
* VillainRespect: He hates Dexter, but respects him.

[[folder: Mandark's Parents (Windbear and Oceanbird)]]

* AbusiveParents: Mandark's parents. While they're not the worst examples of the trope, they aren't very supportive of Mandark's love for science, and they gave him a name [[spoiler:Susan]] that would subject him to a lot of ridicule from other kids.

->Voiced by: Creator/FrankWelker, Creator/CoreyBurton (speaking voice in "The Lab of Tomorrow")

* TheAce: Monkey InUniverse is the most powerful and respected hero on the planet.
* ActionPet: When off duty, his personality is similar to Dee Dee's and he is often seen playing with her in the laboratory, but when it is time to save the world Monkey is extremely serious and heroic and risks his very life to ensure the safety of the world and those he loves.
* BadassAdorable: Monkey is considered to be one of the Dexterverse top superheroes.
* BatmanCanBreatheInSpace: Apparently his energy field provides life support for himself and passengers.
* ABirthdayNotABreak: The banned "Barbequor" episode took place when the other heroes threw a birthday party for him, but even after he defeated the Barbequor and the Silver Spooner, Monkey wasn't able to enjoy his birthday because he then had to give Krunk a ride home and Krunk kept on giving very lousy directions on where his home was.
* BoxingLessonsForSuperman: When Huntor's technology completely counteracts Monkey's powers, Monkey defeats the villain using only his skills, brains, and - uh - guerilla tactics.
* {{Determinator}}: In his fight with Rasslor, he kept on being knocked down, and ''wouldn't give up''. Rasslor threw the fight (and decided not to destroy the Earth) because of this.
* ADogNamedDog: A monkey named Monkey.
* EverythingsBetterWithMonkeys: Thanks, CaptainObvious.
* FlyingBrick: He can generate an energy field around his body that gives him this set of powers.
* FurryReminder: Monkey is intelligent, but his instinctive reactions, body language and problem-solving skills are all quite simian.
* HeroicSpirit: He can be defeated (with humorous ease in some cases), but he'll ''never'' surrender.
* InterspeciesRomance: He is often paired with his sidekick and girlfriend Agent Honeydew on his missions who he cares about deeply and appears to posses a psychic link with her.
* LovesMyAlterEgo: Non-romantic example. Dexter admires the super hero Monkey and has no idea that his lab monkey leads a double life. He remains thoroughly unimpressed that his monkey failed to developed super powers.
* NarratorAllAlong: "The Lab of Tomorrow" ends with the revelation that he was the one narrating the episode. No explanation is given for how he became capable of human speech.
* OutOfFocus: His appearances became less frequent in the final two seasons. He did get a ''bizarre'' DayInTheLimelight episode, though.
* RidiculouslyCuteCritter: Monkey is cute both in and out of costume.
* SecretIdentity: As Dexter's lab monkey. Dexter and his family are completely unaware of his double life.
* SuddenlyVoiced: Is revealed to have become able to speak at the end of "The Lab of Tomorrow".
* {{Superhero}}: Considered the world's greatest superhero.
* TalkingTheMonsterToDeath: Convinces Simion, another super-simian, to abandon his plan of destroying the Earth in favor of swinging around in a jungle. Not bad for somebody who can only make monkey noises.
* YourCheatingHeart: Despite having Agent Honeydew as a girlfriend, "A Quackor Cartoon" shows him falling in love with Quackor, and in the later episode "Used Ink", one of the things that he asked for was a girl monkey implying that his relationship with Quackor might be over and he is looking for a new love. However in one of the final episodes of the series "Dexter's Wacky Races", Monkey is shown to be back together with Agent Honeydew. All of this was never explained.

* ActionGirl: As part of her agent training, she is a trained fighter who is proficient in firearms.
* BoyishShortHair: She has short black hair with curly bangs.
* HartmanHips: Agent Honeydew has wide hips. The bodysuit helps!
* InterspeciesRomance: Despite their different species' (and the questionable ethics of this), it appears that Monkey and Honeydew's relationship is very close and romantic, as both are often seen going out on dates when off duty, sharing romantic dinners and Monkey staying over at her house where they apparently bathe together while she grooms him.
* MsFanservice: She is a sexy spy.
* RavenHairIvorySkin: Has pale skin and black hair.
* SpyCatsuit: She wears a violet-blue S.H.I.E.L.D.-style jumpsuit when is in mission.

* RoguesGalleryTransplant: According to the ''WesternAnimation/ThePowerpuffGirls'' episode "Bought and Scold", Quackor the Fowl is somehow one of their enemies.
* SamusIsAGirl: [[spoiler:Implied in her second appearance; she and Monkey not only fall in love, but she lays an egg. So she's either a girl or a MrSeahorse]].
* UndyingLoyalty: Implied to have this for Mandark in her debut episode, seeing as she goes off to destroy Dexter's lab after hearing Mandark mumble about wanting to do so in his sleep.

* LargeHam: Major Glory takes this UpToEleven.
* TheLeader: Of the Justice Friends.
* PoliticallyIncorrectHero: His appearance in the ''WesternAnimation/ThePowerpuffGirls'' episode "Members Only" makes him highly sexist towards the Powerpuff Girls by denying their request to join his team just because they are girls. His rude treatment of the Powerpuff Girls is also suggested to have ageist motivations because he also refuses to take them seriously just because they're young.
* SmugSuper: He's pretty egotistical about his powers.
* TeamDad: He may also be the TeamMom depending on the situation.
* TookALevelInJerkass: His appearance in the ''WesternAnimation/ThePowerpuffGirls'' episode "Members Only", where he is portrayed as sexist and ageist towards the Powerpuff Girls and also isn't very nice to the other heroes on his team.

* ShoutOut: To Van Halen, and HeavyMetal (mainly HeavyMithril, what with his Viking motif) in general.
* TotallyRadical: Most of his dialogue.
