Cthulhu

Described as a giant man with an octopus head and dragon like wings, Cthulhu is as menacing as they come. Introduced in “The Call of Cthulhu” by H.P. Lovecraft in 1928, this scary looking f*cker has been popular in things like video games, fan-fiction stories, and even religions. (And in case you’re wondering, it’s pronounced Ka-thu-loo.)
