Stickleback Mutant

The Stickleback Mutant (voiced by Eiji Maruyama) is a stickleback Gorgom monster.

The Stickleback Mutant was first seen when the Gorugomes Fruits were becoming scarce.

The Stickleback Mutant was later seen when the Gorgom High Priests became Grand Mutants.

The Stickleback Mutant later catches three Gorgom Mutants trying to flee from the headquarters and kills them. The Stickleback Mutant was ordered by Shadow Moon with the task of eliminating the Whale Mutant. The Stickleback Mutant ambushes Kohtaro and the Whale Mutant and drags the Whale Mutant underwater. The Stickleback Mutant starts to overwhelm the Whale Mutant. Kohtaro catches up to them and transforms into Kamen Rider BLACK. The Creation King intervenes and pulls Kamen Rider BLACK to his palace where Shadow Moon is waiting. The Stickleback Mutant succeeds in its mission.

The Stickleback Mutant alongside the Handmaiden Mutants watched the fight between Kamen Rider BLACK and Shadow Moon. After Shadow Moon was taken down, the Stickleback Mutant stepped in to fight Kamen Rider BLACK. Kamen Rider BLACK easily avenged the Whale Mutant by killing the Stickleback Mutant with the Rider Kick.
