A kaiju from Godzilla (Series) series.
Gigan is a peculiar Alien Cyborg kaiju with several parts of its body modified with cybernetic parts. Most notably a large Visor Cap, a hooked blade in place of an arm, and a saw blade protruding from its stomach.
It was generally depicted as being controlled by an alien and used as a weapon to aid in their intergalactic conquest.
