The Omegaman is ?
Originally one of Neptune King's Perfect Choujin. He was a bounty hunter for the Choujin Enma who retrieved choujin who escaped from hell, including Screw Kid, Junkman, Atlantis, Sunshine and Sneagator. During the Survivor Match for the Kinniku Throne, he was involved in another such mission to retrieve Neptuneman. While on Earth, he joined Kinnikuman Super Phoenix's team. Omegaman defeated Geronimo with the Omega Catastrophe Drop which resulted in a tag match, Neptuneman and Kinnikuman vs. Omegaman and Super Phoenix. The match was for each person's page in the Muscle Prophecy book. The pages were tied to a string which hung over a torch. Neptuneman ended up losing his page and dying. This pitted Kinnikuman and Omegaman against each other. Omegaman used his Omega Metamorphosis technique which turned him into Prince Kamehame. Through the course of the match, Kamehame's spirit took over and he finished teaching Kinnikuman the Kamehame 100 Special Techniques. With those techniques at hand, Kinnikuman turned Omegaman back into himself and defeated him with the Muscle Spark. Omegaman's prophecy page was then burned, and he faded from existence.
