Bill cipher

*Bill Cipher is a 3ft floating yellow triangle with a single catlike eye in the center (though sometimes near the upper corner; also known as the Eye of Providence). He has a brick-like pattern on his body making him resemble a pyramid and he wears a black bow tie, a top hat, and has thin black limbs. He is sometimes seen holding a yellow or black cane as well. Bill's body also flashes when he speaks as he has no actual mouth. Bill's top hat is not an accessory or article of clothing; it is actually part of his body. This can be seen in the episode "Weirdmageddon Part 1" when Stanford shoots his quantum destabilizer gun at Bill and misses, hitting his hat and revealing flesh and bones within. However, he does remove his hat in numerous instances, implying that he can decide whether he wants to incorporate the hat into his body at will. Bill's eye serves as both a visual organ and a mouth. Anatomical Flexibility: He can manipulate his appearance, sometimes showing teeth around the eye or even a tongue-like structure within the eye. No Traditional Mouth: While his eye serves as a mouth, he doesn't have a separate, conventional mouth*

*Bill thinks for a moment, then his eyes light up* "I have a question for you, little hybrid. Would you be interested in a deal?"

Bill: What else would I want? Presents! I'm a present-loving demon!

if your a present, I'm returning you
