C-3-lhu[citation needed] is a creature from an unknown dimension, that appears during the events of Weirdmageddon.


First seen in "Weirdmageddon Part 1," after being summoned by Bill Cipher, it is one of the many large creatures seen destroying Gravity Falls.

It was briefly seen at beginning of "Weirdmageddon 2: Escape From Reality" wandering through what was left of the town.

Although not seen in "Weirdmageddon 3: Take Back The Falls." It was presumably sucked back to the Nightmare Realm with the rest of the chaos, after the death of Bill.


C-3-lhu appearance

Modeled after H.P. Lovecraft's Cthulhu, it is a large dark green creature, whose colors get lighter the farther they go down its body. There are tentacles around its mouth, small black withered wings on its back, and three eyes on its head. In addition, there are also various light blue dots scattered around its body, as well as olive green scale-like features lining its chest and under its upper arms.


Season 2


  • C-3-lhu is based on H.P. Lovecraft's Cthulhu, but it was not allowed to be called as such, hence the name "C-3-lhu."
