Principal McVicker is the main antagonist of Beavis and Butt-Head. He is voiced by Mike Judge. As (former) principal of Highland High School, he is one of Beavis and Butt-Head's main victims (arguably their biggest). The duo often causes him trouble, frequently calling him "McDicker" and damaging his school along with his mental health. As a result, he stutters frequently and acts rather harsh, especially towards Beavis and Butt-Head, whom he hates more than anything else.
