Mephis

Origin
Capturing Rod Rian of Sky Patrol and Andres of the Moon Squadron, the Mephestians return them to the planet Mephestos. There, they are taken before "His Satanic Majesty, Mephis, ruler of all Mephistos". Mephis has Rian thrown to his pet, a giant gorilla-like creature named Carno. Rian escapes the clutches of Carno and attempts to escape with aid of Karin. When he is recaptured, Mephis sentences him to the Island of the Living Dead.
