Beetlejuice (played by Michael Keaton) is the main antagonist in the 1988 film Beetlejuice and its sequel. An evil ghost and freelance "bio-exorcist," he can be summoned by saying his name three times. Beetlejuice uses extreme methods, including attempted murder, to rid homes of humans. After nearly killing people and trying to marry Lydia, he's banished to the Netherworld. In adaptations, he's portrayed as an anti-hero in the animated series and given more depth in the musical.
