A Marowak evolution... Seriously, who didn't see this coming?! XD Still a pure ground type... and he doesn't have only one arm... I was just lazy... X3

*Flips open Pokedex* Marowrex, the Bone King Pokemon. Marowrex is the evolved form of Marowak. Upon holding the Relic Bone and learning Ancient Power, Marowak becomes Marowrex and a devistating powerhouse among Pokemon. Easy to anger, caution must be taken with those looking to tame this pokemon's power.
