A member of the Karikoni, an Eternian race of crustacean warriors, Clawful as he was known outside of Orkas Island, became a core member of Skeletors Evil Warriors after he saved Beast Mans life from a Seclapoid attack. Clawfuls hard shell protects him from both extreme heat and cold. Under a spell cast by Evil Lyn, Clawfuls dull wits were enhanced, turning him into a keen warrior and strategist. He fought alongside Skeletor, leading a battalion of Skeleton Warriors during the Second Ultimate Battle Ground. Clawful uses his dreadful claw to work his evil will!
