Marowak is the Bone Keeper Pokémon. It has a brown body with a sandy-colored underside. It has a single claw on its hands and feet. Its tail has a single protrusion near the end. The Pokémon's head seems to be an exoskeleton helmet and wields a long bone.
Marowak can have one of two abilities, Rock Head or Lightningrod. Rock Head prevents Marowak from taking Recoil Damage from using moves like Double-Edge. Lightningrod causes all Electric-type attacks to target Marowak. From its birth, this savage Pokémon constantly holds bones. It is skilled at using them as weapons, throwing them with great skill like boomerangs to KO foes. Its attack power doubles when wielding a club.
