Characteristics
Of the title characters, Butt-head appears to be the leader of the two. He is calmer, cockier, older, and marginally more intelligent than Beavis, but is oblivious to subtleties, semi-literate and still significantly less intelligent than the other characters in the show. Regardless, as the 'leader', he is usually 100% confident in everything he says and does – no matter how ridiculous or frivolous it is. Dan Tobin of The Boston Phoenix described Butt-head as "ringleader, the devious visionary."
Butt-head seems to be the lazier of the two. He never seems to react to things unless they catch his attention, in which case he describes them as 'cool'. Beavis, on the other hand, always has some kind of reaction, although his actions predictably end with bad results.
Butt-head has a severe overbite, wears dental braces, and has brown hair and squinted eyes. His top gums are often exposed and he speaks nasally with a deep voice and a slight lisp, repeatedly punctuating his speech with his trademark laugh (Uh huh, huh huh). He is usually shown wearing an AC/DC t-shirt. In merchandising appearances, his shirt displays the word 'Skull', to avoid licensing issues.
Though Butt-head is physically weak to the point of being unable to lift a bar without weights (Buff n' Stuff) even with help from Beavis, he still seems to win most fights with Beavis.
Butt-head's parents are not seen, except for in Beavis and Butt-head Do America. His dad is shown as a former Mötley Crüe roadie voiced by David Letterman and his mother in "This Book Sucks." In the movie, Butt-Head and Beavis and their fathers part company before they make the rather obvious connection.
