Beetlejuice

'''"Ah. Well. I attended Juilliard.﻿ I'm a graduate from Harvard Business School. I traveled quite extensively. I lived through the Black Plague and I had pretty good time during that. I've seen the Exorcist about a hundred and sixty-seven times! And it keeps getting funnier, EVERY SINGLE TIME I SEE IT! NOT TO MENTION THE FACT THAT YOUR TALKING TO A DEAD GUY! NOW WHAT DO YOU THINK?! You think I'm qualified?"

- Beetlejuice on his qualifications. '''

Beetlejuice is an evil spirit and a nasty ghost who acts as the protagonist villain in the 1988 live-action film "Beetlejuice" as well as a more anti-heroic character in the cartoon series that followed.

In the movie, Beetlejuice was darker and more openly malicious than he would become in the cartoons, arguably being one of the main villains - though he also acted as a benefactor (of sorts) to the heroes: though there was no attempt to hide the fact that Beetlejuice was not meant to be a nice character, even the heroes that summoned him knew that he was, pretty much, a demon.

But Beetlejuice was still used as a force of (relative) good as his chaos was directed largely at a group of human antagonists - though he was still rude, obnoxious, and hostile towards the heroes as well, not to mention the fact that he also tried to force one of the main heroes to be his unwilling bride - much to her disgust.

Beetlejuice was originally an assistant to Juno until he went on his own as a freelance bio exorcist. Until Juno banished him in a model cemetery, it wasn't long until he was released from his model prison and once again spread chaos.

As mentioned before when the Beetlejuice cartoon came out they altered his personality somewhat and while still being an agent of chaos and a fairly macabre character he was more heroic than he had originally been portrayed in the film and even had a human friend (ironic considering in the original film he labelled himself a "bio-exorcist").
