Nintendo and GameStop have announced that starting March 4th, Pokemon fans who own Pokemon White 2 or Pokemon Black 2 can head to their local GameStop to receive Meloetta, a new legendary Pokemon:
Meloetta (Japanese: メロエッタ Meloetta) is a Normal-type legendary Pokémon.
While it is not known to evolve into or from any Pokémon, it has a second Forme activated by using the move Relic Song in battle. Its original Forme, Aria Forme, will then become Pirouette Forme.
It would appear as though Nintendo and GameStop are offering this new legendary Pokemon to build hype for the release of Pokemon X and Y, set to hit stores in October!
