The Gigan (ガイガン Gaigan?) of the AniGoji continuity was a nanometal-infused, Bilusaludo controlled kaiju that made its first appearance in Godzilla: Project Mechagodzilla.
It is mainly based around Godzilla trying to make or play with his friends, only to be confronted by a monster that is causing trouble, leading to a battle between it and the King of the Monsters.
