Baoh: The Visitor

Doress, a Japanese "black projects" organization, has been gathering psionics and making biological weapons to "make Japan superior". When one of the biological experiments, BAOH, escapes with a young girl, Doress will do anything to get the boy and girl back. For BAOH is a parasite living in its host's brain, altering the host into a living death machine in order to keep it alive.
