It's Bill Cipher from Gravity Falls. He's the one and only Demonic Dorito! The character who often makes you wonder why the heck Gravity Falls is rated Y-7! The guy who is obsessed with asserting his presence by taking more intimidating forms! His hobbies include taking advantage of people, summoning the apocalypse, calling Dipper "pine tree", and more!
