Gardevoir

Gardevoir is a Psychic/Fairy-type Pokémon (before Generation VI, purely Psychic-type) that is as of Generation IV one of two evolved forms of Kirlia (the other being Gallade) and the final form of Ralts. As of Generation VI, Gardevior can Mega Evolve into Mega Gardevior. It has appeared in Pokémon series since Pokémon Ruby and Sapphire.

Starting with Super Smash Bros. Brawl, Gardevoir appears as Poké Ball Pokémon. When summoned, it uses Reflect to create a large circular barrier around itself and wanders around the battlefield. Despite being harmless, the shield can deflect projectiles back at the foes, although it does not affect those who summoned Gardevoir.
