Cosmoem

Protostar Pokémon (Legendary) ^#790

The absorption of starlight fuels this Pokémon’s growth. The shell that encases it is harder than any known material.

It sucks in dust from the air at an astounding rate, frantically building up energy within its core as preparation for evolution.

- Sturdy
  When this Pokémon is at full HP, any hit that would knock it out will instead leave it with 1 HP. Regardless of its current HP, it is also immune to the one-hit KO moves: fissure, guillotine, horn drill, and sheer cold. If this Pokémon is holding a focus sash, this ability takes precedence and the item will not be consumed.

As it absorbs light, Cosmoem continues to grow. Its golden shell is surprisingly solid.
