Baoh

Ikuroo, an innocent young man, becomes the host of Baoh, a parasite implanted in his brain by the organization Doress. It makes him nearly immortal and allows him to transform into a powerful beast when he is in danger. Doress plans to use him in a bid for world domination. As the organization transports Ikuroo, Sumire—a young psychic girl held captive by Doress—sets him free, and the two escape together. But Dr. Kasuminome, the mad scientist behind the experiment, is determined to recover his test subject. He has superpowered henchmen and a small army at his disposal.
