Canto

Canto was a malevolent alien presence encountered by John Robinson. He was the spirit of a long-dead warrior still intent on conquering the universe. He took over Robinson's mind, although the professor resisted as long as he could. With his superior intelligence, Canto was able to direct John in beginning the necessary preparations for the Jupiter 2 to leave Priplanus and resume his plans of conquest. Ultimately, Canto's spirit is driven out by John who is spurred on by his son's love.
