Origin
Melanicus was a Kalichura, whose race lived in the Althrace galaxy. After trying to conquer galaxy they lived in, he fled to another dimension. He came into contact with Catavolcus, a tyrant from earth in the third century, and persuaded the tyrant into summoning him into Earth's dimension via a magic ceremony, and thus joined forces to form an alliance.
