Shaymin (シェイミ Shaymin) is a Pokémon from the Pokémon universe. It's a pure Grass-type Pokémon in it's Land Forme and a dual type Grass/Flying type in its Sky Forme.
Shaymin appears in Super Smash Bros. for Nintendo 3DS on the Unova Pokémon League stage as a background character. It initially appears in its Land Forme before transforming into its Sky Forme and flying away.
NA: When in its Land Forme, this Pokémon sports a fetching pink flower. In Sky Forme, it can take to the air with ease. This Legendary Pokémon is hard to find, but it can sense anyone with a grateful heart. This ability is where the name "Gratitude Pokémon" comes from.
PAL: No wonder this Mythical Pokémon is so hard to find! In its Land Forme, it looks just like a flowery patch of grass. Good luck spotting that in a field! Shaymin has two different forms, though, and in Sky Forme, it can fly. In both forms, Shaymin reacts to gratitude, hence its nickname: the Gratitude Pokémon.
