Bill Cipher is the primary antagonist of the Disney cartoon Gravity Falls.

Canon

Bill is a dream demon. He appears as a triangle (like a 2D pyramid) with limbs, one eye, a top hat, and a bowtie.

Fandom

Anthro/Human Art

Bill has been drawn as an anthropomorphized human who character design takes inspiration from Bill's canon appearance. He is often drawn as a tall, skinny white man wearing a top hat and yellow suit, with either an eyepatch, long bangs, or both covering one eye. This depiction has been both parodied and embraced by the Gravity Falls fandom as an archetypal example of a tumblr sexyman. Notably, Alex Hirsch himself drew an "unsexyman" version of Bill Cipher's humanization during a livestream.

Shipping

Some of the fandom views these ships as very problematic, mainly because of Bill's treatment of... well, everyone, the power imbalance, and the young age of the twins. Despite this, as of 2022, Billdip is the most popular Gravity Falls ship on Archive of Our Own by a large margin.

"This is based on the premise that Bill’s dimension was Flatland - a two-dimensional, strictly-regulated world inhabited by geometric figures, where each one’s place in society is determined by the number of their sides. The whole story is told through the memoirs of A Square, who is shown the existence of a tridimensional world - only to be imprisoned by authorities to keep him from speaking of it. Said memoirs are exactly how Bill will find out about other dimensions, too." — Author's note on the first chapter.
