Bill Cipher debuted in Gravity Falls, the Disney animated mystery series that ran from 2012 to 2016 and was created by Alex Hirsch, who also voiced the character. Set around the Mystery Shack in the woods of Oregon, the show built a devoted following for its codes, journals and supernatural lore. Clips of Bill's entrances were shared widely in fan edits and soundboards after the finale, and his distinctive laugh and theatrical entrances kept the sound alive as a shorthand for weird, interdimensional chaos invading an ordinary place.
