MD Cipher

Appearance: Bill is an infected worker drone with yellow eyes (sometimes ones covered with a yellow riangular eye patch), yellow hair tied up in a short low ponytail with black highlights, yellow suit with a black shirt underneath, black bowtie on his neck, A black top hat on his head, optional black cane, optional bill cipher necklace either around his neck or wrist, yellow smiley face sticker on his cheek, black pants, permanent crazed look, brown heeled shoes with white on the front half and a yellow triangle on the inner side, A long tail with a yellow one eyed triangle at the end, looking like a demons tail.

In the book Dipper and Mabel and the Curse of the Time Pirates' Treasure!: Select Your Own Choose-Venture it is strongly implied by the Axolotl's poem about Bill that he's an equilateral triangle: the first verse says "sixty degrees that come in threes", and equilateral triangles have three internal angles of 60° each.[14]

However, when he gets angry, his voice deepens significantly, the color of his hair, eyes, suit, etc. Turns red and everything on his body that was previously black turns white.

When possessing someone, that person's skin becomes pale and their eyes become yellow with black slits like Bill's. The voice also changes to Bill's.

In the Book of Bill, after being sent to the Theraprism, Bill is now shown cracked with glitches being exposed after being punched by Stan.

Personality: Bill is a cunning, blasphemous, eccentric, sadistic, psychopathic and physically irreverent being who finds most things amusing, particularly if they cause distress or harm to others. He is outrageous and outlandish, as well as a quick talker and thinker. Though he may come across as simply annoying, he shouldn't be underestimated; for when he is angered, he is a force to be reckoned with as he will unleash his near-omnipotent powers on those unfortunate enough to make him angry. When accused of being insane, Bill proudly agrees with the statement. He is also shown to be somewhat obnoxious, as seen when he makes his presence known to Dipper when the latter is trying to figure out a password within a limited amount of time. Occasionally, his voice tumbles to a lower pitch (usually when emphasizing a statement). He also tends to get drunk a lot.

As a demonic dealmaker, Bill is also shown to be a highly manipulative, very charismatic and charming conman being able to easily trick Ford Pines into believing that he was just a humble muse who simply wished to help benefit the human world by providing him with forbidden knowledge when in reality he was only ever using the researcher for his own purposes with the book smart Ford noting that the only person who could've possibly seen the ruse for what it was, was his much more street smart brother Stan Pines, who was himself an expert conman.

Bill is not one who believes in rules. Instead, he follows his own selfish philosophy which means doing whatever he wants without care for the consequences. He thinks of laws and physics as senseless and displays an irresistible urge to break those rules down by causing absolute chaos however he can. The lives he ruins hold no merit to him and he finds amusement in tormenting and turning people's worlds upside-down. He also sees reality as "an illusion" and values its destruction.

When possessing Dipper's body, Bill is shown to be rather masochistic, hurting himself in various ways for the thrill of it, exclaiming that "pain is hilarious." He seems to have little knowledge about the human body, specifically its physical limits. This comes back to haunt him when he fights Mabel over Journal 3, as he eventually falls down, physically exhausted.

As shown in "Weirdmageddon Part 1," he also reacts sadistically whenever a would-be subject oversteps their boundaries, such as when he shuffles "the function of every hole in Preston Northwest's face", and in "Weirdmageddon 3: Take Back The Falls" when he decides to kill one of the Pines twins "just for the heck of it."

Bill also suffers from PTSD and Survivors Guilt. Though he repeatedly claims to feel no regret over the destruction of his home dimension even going so far as to say that he had "liberated" them from their dull lives, it is shown repeatedly that this is just another lie he tells himself to avoid the truth. Though he immediately brushes it off, in The Book of Bill, he shows a rare moment of genuine remorse as he recounts the destruction of his dimension. Stanford also recounts a time from one of the lost pages of Journal 3 where he and Bill talked about the destruction of his home, with a shocked Ford asking what it was destroyed by, to which Bill stared off into space for a while and replied in an uncharacteristically somber tone of voice "By a monster." On the silly straws page, there is a code which once deciphered says "Twisted out of shape after the kill, the ghosts of his family are haunting him still."
