Dexter's Laboratory/Characters

Dexter

 * AcCENT Upon the Wrong SylLABle
 * The Ace: When it comes to science, of course. There was even an episode where one of his teachers clearly has the hots for him.
 * Aloof Younger Brother: To an extent.
 * Anti-Hero: Type III
 * Badass Bookworm
 * Big Good: In "Ego Trip".
 * Butt Monkey: Nothing goes right for this kid. Nothing.
 * Child Prodigy
 * Chew Toy
 * Crouching Moron, Hidden Badass: 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. Rule of Funny is involved, but still.
 * Depending On the Writer: How smart he is can differ from episode to episode.
 * Eye Glasses
 * Insufferable Genius
 * Foolish Sibling, Responsible Sibling: The responsible to Dee Dee's foolish.
 * For Science!: Catch Phrase

Dee Dee

 * All Girls Like Ponies
 * Annoying Older Sibling
 * Art Evolution: Had thick eyebrows and seemed to lack a chin in early episodes.
 * Cloudcuckoolander
 * Depending On the Writer: How nice or annoying she is varies from episode to episode.
 * She also flip-flops from stupid to a Straight Man for Dexter.
 * Foolish Sibling, Responsible Sibling: The foolish to Dexter's responsible.
 * Genius Ditz: She has her moments.
 * She gave a somewhat accurate description of Gregor Mendel in the Sasquatch episode.
 * Genki Girl
 * Girlish Pigtails
 * Girls Love Stuffed Animals
 * Idiot Houdini: Dee Dee always made a huge mess of Dexter's lab through her sheer idiocy and yet she never got any repercussion for it.

Mandark Astronomonov

 * All Love Is Unrequited: For Dee-Dee.

 * Big Bad: The closest this series has to one.
 * Breakout Villain: Appeared infrequently in Seasons 1 and 2, became pretty much the 3rd main character by the time the show ended.
 * Child Prodigy
 * Dark Is Evil: His lab in post-finale seasons.
 * Depending On the Writer: He's either a villainous mastermind or just some kid Dexter's rivals with.
 * Evil Counterpart
 * Evil Laugh: "HA haha! HA haha haha!" The fact that he cries, coughs and chews in the same way makes it border on being a Verbal Tic.
 * Embarrassing First Name: Retconned to
 * Fat Bastard: In Ego Trip
 * Flanderization: Became more and more like a stereotypical Evil Genius as time went on.
 * To a lesser extent, his crush on Dee-Dee.
 * Also, he didn't do freaking everything in the same rhythm as his Evil Laugh when he was first introduced.
 * Harmless Villain: After Villain Decay.
 * Hopeless Suitor: Is head-over-heels in love with Dee Dee, who is unaware... at best.
 * Light Is Not Good: Mandark's lab before post-finale seasons.
 * Mad Scientist
 * Multiple Choice Past: He has two different origin stories.
 * The Rival
 * Younger Than They Look: He's (presumably) the same age as Dexter, but he's as tall as (if not taller than) Dee-Dee, and could easily pass for a teenager.
