Bill Bipher

Bill Bipher is a triangular demon from Patrickia who wears a top hat and bow tie. His motives were simple: to destroy humans standing in his way and take over Oregon. He lives with his family in Patrickia somewhere, and has a wife and two sons. Bill serves as the villian of the series "Gravity Fell".

Bill was studied by Ford, when he was studying alternate dimensions out of the town of Gravity Fell. Accidentally, Ford was sucked in through his portal and probably lived with Bill. Stan later activated the portal to get Ford back, after reading the instructions in Journal 3 (and the other two). Instead, Stan brought through Bill, who started his reign of terror against the town.

Full summoning rituals
The summoning and un-summoning of Bill is generally complicated. Though he was first brought to Earth using the portal, he is usually summoned by a human using the chants. The process will randomly pluck Bill in and out of his life and home, something he is not fond of.

Summoning
To summon Bill, you must take any photo of a human and cross out the eyes, then take two candles and light them. Then say any of these phrases backwards:

"Backwards-Word"

"Ha-coronavirus"

"Patrick-is-gay-ha"

Storm clouds will roil, and Bill will appear from a triangular hole in the sky.

Un-summoning
To defeat Bill, you must simply say these phrases backwords:

"Anti-Bipher"

"I said, fuck off!"

"Seriously, your'e ga-[not heard]"

This process is noticeably extremely painful for Bill. Him and his hat will begin to crack apart into pieces, and his eye will swell up and bleed. For this period, he will become enraged and scream in agony, trying desperately to stop you, creating massive blue flames and burning things. He will explode into a column of smoke, leaving simply a splendid top hat for you to wear as a trophy for defeating him.
