Beavis and Butt-Head/Characters

Beavis

 * Anti-Hero
 * Alter Ego: "The Great Cornholio", which emerges when Beavis has too much sugar.
 * Also appears after too much caffeine or drugs.
 * Anti Role Model
 * Berserk Button: Don’t call him "buttknocker"!
 * Beavis Smokes: In some episodes, Beavis is seen smoking.
 * The Chew Toy
 * Cloudcuckoolander
 * Determinator
 * Gonk
 * Hot-Blooded
 * Iron Butt Monkey: He's never had any permanent side effects from his innumerable injuries.
 * Jerk With a Heart of Gold: Although he can be a prick similar to Butt-Head, he's never really been as malicious about it.
 * Made of Iron: Seriously how is he still alive after everything He's been put through?
 * Pyromaniac: "FIRE! FIRE!" It was toned down after that incident with the boy who set his trailer on fire and his mom blaming it on the show (despite that the family didn't have cable TV in their house), but when the show was revived in 2011, they brought it back.
 * Red Oni: To Butthead's blue.
 * Signature Laugh: "HEH HEH", does this very often to the point it's pretty much how he breathes.
 * Too Dumb to Live

Butt-head

 * Anti-Hero
 * Anti Role Model
 * Blue Oni: To Beavis's red.
 * Casanova Wannabe
 * Deadpan Snarker: In his own dumb way.
 * Determinator: Like Beavis, it going to take a lot to stop Butthead on his quest… even if it means death.
 * Gonk
 * Jerkass
 * Even Butt-Head Has Standards: He'll go out of his ways to see a naked women, but he draws the line on a naked man and seeing a woman give birth.
 * Everyone Calls Him Butt-head: Even teachers and other professionals, one wonders if that really is his name?
 * The most popular Fanon name for him seems to be Buford.
 * Full-Name Basis: It's not just his real name, it's his first and last names combined! One episode has another person asking Butt-head his name. He replies that it's "Butt". When the other character asks what his family name is, he replies "Head".
 * Which makes you wonder if Beavis's full name is Beavis Head, if you buy the fan theories about him and Butt-head being half-brothers or cousins...
 * Major Injury Underreaction / Only a Flesh Wound: In "Whiplash", he gets ran over by a school bus and his reaction... "that was cool".
 * Signature Laugh: "UH HUH UH", like Beavis, does this very often to the point it's pretty much how he breathes.
 * Too Dumb to Live

Stewart Stevenson

 * Butt Monkey: He'd be the Chew Toy if he appeared more often.
 * With Friends Like These...: Though Beavis and Butt-head don't consider him a friend.
 * Take That: Wears a "Winger" shirt and his wimpiness is compared to the main duo's Metallica and AC/DC shirts.

Daria Morgendorffer

 * Characterization Marches On: Especially evident in the Marvel tie-in comics. She starts out as a more generic know-it-all but gains the wry, unflappable, sarcastic streak we all know and love later on.
 * Deadpan Snarker
 * Ensemble Darkhorse: Enough to receive a spinoff that became just as popular, if not more, than the original show.
 * Hollywood Pudgy: Was shorter and slightly chubbier in this series.
 * Only Sane Woman
 * Meganekko

David Van Driesen

 * Cool Teacher
 * Hippie Teacher: Literally. He looks as if he's still living in the 1960s.
 * Granola Girl - Rare Male example.

Coach Buzzcut

 * Drill Sergeant Nasty
 * Sadist Teacher

Cassandra

 * Talking to Herself: Played by Tracy Grandstaff, better known as the voice of Daria.

 * Granola Girl

Hamid

 * Butt Monkey: Is constantly on the receiving end of the boys' antics.
 * Funny Foreigner: Appears to be from somewhere in the Middle East.
 * Honest John's Dealership: Hamid himself isn't particularly unscrupulous but he does end up working for one at one point.
 * Why Do You Keep Changing Jobs?: He's at a new job each time we see him, usually because Beavis and Butthead did something to get him fired from the last one.
