Gigan (ガイガン Gaigan?) is an alien cyborg kaiju created by Tohothat first appeared in the 1972 Godzilla film, Godzilla vs. Gigan. Gigan is truly a strange monster, sporting a circular saw weapon located in his frontal abdominal region, large steel hooks for hands with smaller ones for toes, spikes running down his tail, three, large fin-like spines on his back and a red cybernetic visor for an eye.

He also bears various avian characteristics, such as a 'crest' made of metal spines and a metal beak. In the Showa series, Gigan's skin was a dark green color and he possessed golden scales over several parts of his body. In Godzilla: Final Wars, Gigan's appearance was changed to make him appear more cybernetic. In this film, Gigan's skin is now a dark blue, his body is much thinner and more streamlined, and there are wire-like structures running across his body.

When Gigan is revived as Modified Gigan, his hook hands are replaced with double-pronged chainsaws. Gigan's new design for the Millennium series was praised by many and ranked among fans as one of the best improvements to any monster.


It made its appearance in the final battle as it along with Mechagodzilla fight against Iron Giant, Optimus Prime and Bumblebee.
