Details on the mythical Pokémon, Meloetta, for "Pokémon Black 2" and "Pokémon White 2" were dropped by The Pokémon Company on Monday. We've learned how the the special Pokemon available only through a GameStop distribution event changes form along with receiving new screenshots and a video showing the character in action.
Here is the official description of Meloetta from the Pokémon Company.
Meloetta is the rare and powerful Melody Pokémon that keeps opponents on their toes with its one-of-a-kind ability to alter Formes in the middle of battle. Players who attend the GameStop distribution event will receive Meloetta at Level 50 in its Aria Forme, in which it fights as a Normal- and Psychic-type Pokémon. If a battle calls for a change of tone, Meloetta can switch to its Pirouette Forme and become a Normal- and Fighting-type character—the first-ever Pokémon with such a type combination.
Meloetta changes Formes using Relic Song, a special damage-dealing move that can only be learned when Meloetta is added to your party and listens to the music of a guitar player at Café Sonata in Castelia City. When players receive Meloetta at the distribution, however, it will already be outfitted with a suite of powerful moves—Close Combat, Teeter Dance, Psychic, and Round.
Owners of the original "Pokemon Black and White" and "Pokemon Black and White 2" can download Meloetta to their Nintendo DS or 3DS at GameStop. The distribution event runs from March 4 through March 24. Players will need a Pokédex within the game and no more than 11 Wonder Cards in their possession.
