Attacking an underwater civilization and the surface world, these creatures were led by the massive Gakuzomu on a mission to destroy all life on Earth. When Gamu and Team Marlin of XIG discovered the underwater city, they were attacked by the Gakuzom and knocked out. Annoyed by their interference, Gakuzom led the fish-like creatures to the surface but the mighty behemoth was attacked by the combined forces of Ultraman Gaia and Ultraman Agul. Knowing it couldn't defeat both, Gakuzom summoned its army to join with its body, transforming him into Super Gakuzom.
