Violent Spirit Hidouman (ヒドーマン Hidōman?) is a cyborg who is a master of the tachi and the spiked ball on a chain. He battles with both of these weapons on a single chain. While engaged in a secret meeting in an active mineshaft, one of the miners accidentally witnesses the event. Hidouman is assigned to silence the miner, so he takes the miner's family hostage, which lures Metalder into battle. Metalder confuses him through duplication techniques inspired by a previous fight with Galador, and then strikes his hand to separate him from his weapon. Metalder then destroys him with his Laser Arm attack, which also splits him in half.
