tetrahedonist | Chronological Canon / Extracanon Timeline

Bill's portrayal is drawn from several sources, in rough chronological order;

Flatland (1884)
- Published by Edwin Abbot Abbot, Flatland describes Bill's home dimension (or one very much like it). It is a terribly conservative place where irregularity in form, colorisation and originality are punished by death, prisons and insane asylums exist to maintain conspiracies of the people in power, and one's body type is the caste progenitor of their entire destiny. Hints indicate this dimension is now in very bad shape, along with (almost) everyone in it, including Bill's family.
Gravity Falls: Journal 3 (2016)
- This journal is an extracanon supplement to the show and its inclusion in canon is a little too complex for a small blurb, but it is important and included regardless. More on this TBA.
Dipper and Mabel and the Curse of the Time Pirates' Treasure!: Select Your Own Choose-Venture (2016)
- This book includes a chance meeting with an ancient, powerful entity called the Axolotl, who recites a poem about Bill:
  Sixty degrees that come in threes / watches from within birch trees.
  Saw his own dimension burn / misses home and can't return.
  Says he's happy. He's a liar / blame the arson for the fire.
  If he wants to shirk the blame / he'll have to invoke my name.
  One way to absolve his crime / a different form, a different time.
Gravity Falls (2012)
- In the show, Bill is trapped in a cast-off, otherdimensional bubble that is decaying around him. He's been trying to get to Earth by interfering in segmentations from 10,000 years ago to the modern age (2012ish). Throughout, making djinni-style deals, he aims, ultimately, to unravel the fabric of reality and continue to climb dimensions, destroying the laws (and lawmakers, as this universe has actual sentient entities policing each dimension) that govern each along the way. He is stymied in this goal by the Pines family, and forced to invoke a big favor to survive.
Disney XD: Hero Trip (2015)
- "When the mindscape is broken, all universes begin colliding together. Everyone from each of their respective universes must get back to their proper place before every universe is destroyed for good."
  Kingdom Hearts: Flash Game Edition. Bill Cipher coordinates efforts between residents of several universes (including Dipper and Mabel) to stop the destruction of the mindscape, citing that it will ruin his enjoyment if the mindscape is obliterated. More than this, it's possible that Bill might cease to exist along with everyone else. Also in the endgame, it's implied Bill wanted the stars for personal reasons, don't worry about it. Most importantly, Bill looks kawaii as fuck in this game.
Alex Hirsch's Reddit AMA (2015)
- I have preserved some of these answers as canon, but not all of them.
~~The Book of Bill (2024)~~
- Revisited this book recently and it still sucks. ☹ Almost like other people write Bill way better than Hirsch does (Curse of the Time Pirates' Treasure! was not written by Hirsch, lol)
