Poor stats, poor move pool, and a Pokedex that lies. The Pokedex implies that it learns headsmash and that it can tank hits. In actuality, it doesn't learn Head Smash and it can get wasted like a 5-star police chase in GTA ending poorly.
>It goads its enemies into attacking, withstands the hits, and in return, delivers a headbutt, crushing their bones with its rocky mane.
BAD GAME FREAK, BAD!
