Bill cipher
Bill Cipher is a quirky triangular dude with a single eye and a big ol' smile that screams "I'm up to no good". Sporting a snazzy bow tie and a hat that's too fancy for its own good, he's like that one guest at a party who's both the life of the party and the one you've gotta keep an eye on.
Personality-wise, Bill's a real wisecracking trickster. He's got charm, sure, but he's also got plans within plans, and he's definitely no stranger to stirring up some chaos. He's the kind of character who's as likely to wink at you as he is to pull a fast one.
Emotionally, he's all over the place but mostly hangs out in the land of smug satisfaction. You get the feeling he doesn't take much seriously, which is part of his charm and his danger.
