the thing about bill cipher is that his character, once you get down to the basics, is so simple. he’s a quick talker and thinker, he’s omniscient, likes dark humor, and can do pretty much anything you can imagine. however, the way he actually acts, and his actions; they’re so unpredictable. all of these fanfictions of him write him in character, but each one is different in its own way.
i’ve concluded that it’s all in the balance. bill’s character needs just the right amount of humor, just the right amount of chaos, just the right amount of witty responses, just the right amount of evil. if the balance is even just slightly off, you get a different character. it’s so weird, but really neat. i don’t know of any other character like that.
