Hectorgon is an interdimensional criminal from an unknown dimension[3] who is a member of Bill Cipher's gang.
History
Background
Eons before the events of the series, Hectorgon indulged in criminal activities before being called by Bill Cipher, along with the rest of his gang.[3] Interestingly, he had previously been a sheriff of the very interdimensional law enforcement tasked with hunting Bill's gang down.
Season 2

In "Weirdmageddon Part 1," during the cold open, Bill introduces Hectorgon and the rest of his friends to the residents of Gravity Falls. Afterwards, on Main Street, Hectorgon and the other watch Bill turn Ford into a lifeless golden statue and taunt Dipper before burning the journals. Later, Hectorgon is seen playing "Spin the Person" at the "V.I.P." party Bill is having at the Fearamid, until a calcified Lazy Susan points in his direction and Pyronica happily swallows Hectorgon whole.
In "Weirdmageddon 2: Escape From Reality," Hectorgon (who was likely regurgitated or deposited by Pyronica off-screen) and the rest of Bill's minions attempt to leave Gravity Falls and spread their chaos worldwide, but are stopped by an invisible barrier around the town. He and the others later witness Bill's fury over their inability to leave.
In "Weirdmageddon 3: Take Back The Falls," following Bill's defeat, he is sucked back into the Nightmare Realm along with his comrades.
Appearance

Hectorgon is a red hexagonal being with arms, big gold lips, a big black mustache, a black bowler hat with a gold or aqua band, and an aqua tie. Hectorgon has a small red aura.

Trivia

- Out of all the members of Bill's gang, Alex Hirsch has considered Hectorgon to be his favorite.[3]
- This being's name is a pun combining the name, Hector, and the shape, hexagon.
- According to Gravity Falls Weirdmageddon Theme storyboard, he was supposed to be called "Hexagon."
- Hectorgon has been seen with and without arms.
- Hectorgon is eaten by Pyronica in "Weirdmageddon Part 1," yet appears in subsequent episodes.
- Unlike the rest of the Henchmaniacs, Hectorgon was not involved in the fight against the Shacktron.
- For some reason during "Weirdmageddon 2: Escape From Reality," he lacks his gold aura.
- Originally he was supposed to be an octagon without arms, but was redesigned to an hexagon with arms some point after. His original design can be seen in the deleted scenes from "Weirdmageddon Part 1" and "Weirdmageddon 2: Escape From Reality" in Gravity Falls: The Complete Series.
