Oogie Boogie, the Gambling bug monster
Oogie Boogie is a grand high council member of the Villain League, and is the main antagonist in the Nightmare Before Christmas. He is also the leader of the Transylvanian Monsters, who are exiled evil residents of Halloween Town.
Personality
Oogie Boogie is the sadistic, abusive, and hungry Boogie Man, resembling a large burlap sack shaped like a starfish. Inside of him are thousands of bugs (along with 2 spiders and a snake). His life revolves around gambling, and loves gambling with others' lives. He likes to torture people. He is also apparently "The Shadow on the Moon at Night" as the shadow shown on the moon was an exact replica of him.
The Nightmare Before Christmas
Ironically, Oogie has no skills for gambling; on 3 occasions he rolls snake eyes, and admits he has to resort to cheating----he slams his fist upon the table to shake the dice, resulting in 11. He is also somewhat lecherous, as which is evident when he's easily distracted by Sally's bare (and dismembered) leg. According to Lock, Shock, and Barrel, as well as some of his deleted song material (which is included in the soundtrack version), he is also very good at making a concoction known as Snake and Spider Stew, though it would seem he tends to use people as ingredients. He is a sadist who has his henchmen abduct people and bring them to his lair for him to torture and eventually kill and/or add to his Snake and Spider Stew.
When Oogie Boogie is defeated, it is revealed that he is a colony of bugs wrapped in sacking the main bug which serves as his brain is stepped on by Santa Claus whom had earlier been abducted and delivered to him by Lock, Shock, and Barrel.
Role in the series
Oogie Boogie is one of the more independent members of the Villain League, also lessly shows up at the grand council meetings of the villain leage, evedented when he wasn't there when Alice was captured. as he is most often striking out on his own to pursue other goals besides that of trying to conquer the United Universes.
