Gigan (ガイガン Gaigan) is an alien cyborg kaiju created by Toho that first appeared in the 1972 Godzilla film, Godzilla vs. Gigan. In the Showa series, Gigan is a type of space dinosaur that was transformed into a cyborg by the M Space Hunter Nebula Aliens in order to be used in their attempted invasion of Earth. He is often considered to be Godzilla's most brutal foe during the Showa era and was the first kaiju to make the Monster King visibly bleed.
