Deoxys

Deoxys is one of the types of Pokémon species. They first appeared in the third generation of games, where they had four different forms, including an attack, defense, normal, and speed form. As implied, each form will give a stat boost to the name of it's form (for example, the attack form will raise their attack stats). Deoxys is also a playable character in Pokemon Mystery Dungeon for the Nintendo DS and Game Boy Advance systems.
