C-3-lhu is a creature from an unknown dimension, that appears during the events of Weirdmageddon.
Modeled after H.P. Lovecraft's Cthulu, it is a large, dark green creature. There are tentacles around its mouth, small wings on its back, and three eyes on its head.
- 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"
