About me: Beetlejuice is a trickster and mischievous ghost. According to Betelgeuse, he attended Julliard, is a graduate of the Harvard Business School, traveled quite extensively, lived through the Black Plague (and had a pretty good time during that), and has seen "The Exorcist" about 167 times (and it keeps getting funnier every single time he's seen it, not to mention the fact they're talking to the dead guy). Parts of his qualifications including attending Julliard, graduating from Harvard, and extensive travel are all real life accomplishments. This and other lines were improvised during filming and it is possible that the character of Betelgeuse was lying about certain elements of his past for comedic effect with the Maitlands.
What is known for certain is that Juno warns that he is a troublemaker and does not work well with others. He went out on his own as a freelance bio-exorcist, claiming he could get rid of the living, and got into more trouble.
He used advertisements (such as flyers, business cards and a commercial, where he said some questionable things about chewing and swallowing) to get the Maitlands to hire him as a "bio-exorcist" to rid their house of the Deetzes. They thought it was odd that the business card and flyers contained no address or phone number. The Maitlands summon him when they learn that he can be summoned if his name is said 3 times in a row. When that happened he disappeared into dust.
Things go bad when he starts scaring the Deetzes in ways that seriously harm them, and even worse, plans to marry Lydia as his way of "escaping" the Neitherworld so he can wreak further havoc. Fortunately, saying his name 3 times can also be used to get rid of him.
In the end, he ends up in the waiting room for the deceased, where he is last in a long line. Betelgeuse gets his comeuppance when he steals the Witch Doctor's ticket, then makes a boastful remark. The Witch Doctor sprinkles some powder on him, which causes his head to shrink. However, he, with his higher voice on account of this, remarks this may look good for him in a supposed underwear modeling gig.
He is a very rude, crude, and womanizing ghost. He also gets a little crazy at times. Though he seems fun on screen, it is clear he is not a pleasant person to have around in real life, as he constantly invades people's personal space, does disgusting things like spitting in his own coat and makes rather rude gestures.
He likes to use unpopular words. Not only that, he seems to love to scare people and pull pranks on them. He also appears to be quite selfish, as his main goal in the movie is to lift his curse and escape no matter who gets hurt in the process. He has the attitude of a sleazy used car salesman.
Ironically, he is a corpse who eats insects, including flies and beetles. Beetlejuice could be 600 years old as derived from his line after scaring the Deetzes as a snake implied โI'm feeling a little anxious, if you know what I mean, It's been about 600 years.โ Although his age has never been officially confirmed this line could be the best approximation of his age, which would make his birth at the time of the movie somewhere around mid 1300 A.D if he died in his 30โs.
Though there was no attempt to hide the fact that he was not meant to be a nice character, even the heroes who summoned him knew that he was, pretty much, a demon.
Despite his malicious nature, he also acted as a benefactor of sorts to the heroes. He 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.
He shows an interest in Lydia during most of the movie, and at nearly the end of this movie, he tries to force her into marrying him to fulfill a contract. He almost succeeds until he is stopped by Adam and Barbara Maitland, as well as a sandworm.
Thanks for accepting my request! My character is an OC for the show Once Upon a Time, however, I can always accommodate her story for other verses! I do multi-para and up! I also love banters! If you would love a summary of my character, please let me know!
