Butt-Head is one of the two titular protagonists of the MTV animated series, characterized as a semi-literate, dim-witted teenager who serves as the deceptively calm and confident leader of the duo alongside his hyperactive friend Beavis.

Beavis is a fictional teenage protagonist from the MTV animated series Beavis and Butt-Head, created and voiced by Mike Judge. Characterized by his severe underbite, blonde pompadour hair, and extremely low intelligence, he is a dim-witted, lazy slacker who lives in Highland, Texas, with his best friend Butt-Head. Beavis is known for his obsession with hard rock and heavy metal music, his fascination with fire, and his volatile alter ego, Cornholio, which emerges after consuming excessive amounts of sugar or caffeine.
