Tricephalous is a large green Deviant mutate with three heads, two legs and no arms. It can breathe fire from each of it's heads. It was genetically engineered on Monster Island by the Deviant scientist. Tricephalous once served Warlord Kro in a battle against the Monster Hunters on Monster Island. Tricephalous laid down flames for ground cover as Kro escaped Monster Hunters. Tricephalous eventually became a servant to the Mole Man. He is the Mole Man's air support against his enemies. A similar creature possessing two heads has also been observed in the company of the Mole Man, and could be the offspring of Tricephalous. Tricephalous has yet to show any signs of human level intelligence.
