Synopsis:
Ultra attempts to use an experimental device to change himself back into a human. The machine instead splits him into four individual aliens. His own mind remains in the Ulla, while the other become mindless and destructive.

Ultra tracks down each of his other selves one-by-one. When he approaches the Trago he switches minds with it. Then he is able to subdue the Ulla body. Next he uses the same tactics to capture the Laroo. His final body uses its magnetic powers to keep Ultra at a distance. He summons Bonnie to help him and together they catch his last body. Ultra is then able to reform himself by reversing the experimental device.
