Metagross

Metagross is a unique Pokemon in UU thanks to its Steel / Psychic typing that lets it check Psychic-, Rock-, Fairy-, and Flying-types, its excellent Attack, and its hard-hitting STAB moves. Unfortunately, its low base 70 Speed means it can struggle against other offensive Pokemon, such as Mamoswine and Cobalion, and it finds itself checked by the bulky and omnipresent Ground- and Water-types in the tier. It also faces heavy competition from Cobalion, which has higher Speed, a Dark resistance, and access to moves like Swords Dance that makes it easier to fit on most teams.
