The Pokemon Company has announced a special downloadable Pokemon that will be made available to early buyers of Pokemon Omega Ruby and Alpha Sapphire.
Players who buy the game on launch day will be able to download a Shiny Beldum, which will be available for free via the game's built-in event Pokemon distribution service.
The Shiny Beldum will be holding a Mega Stone, which means when it evolves to a Shiny Metang and then a Shiny Metagross. It can then use the Mega Stone to evolve to a Shiny Mega Metagross.
The news was revealed as part of a new trailer for the game, which also shows off a number of other new Mega Evolutions, including Mega Altaria, Mega Salamence, and Mega Lopunny.
It also confirms that the previously confirmed Cosplay Pikachu can be used in battle while wearing its various costumes.
Pokemon Omega Ruby and Alpha Sapphire are 3DS remakes of the GBA classics Pokemon Ruby and Sapphire, taking advantage of the new polygonal 3D engine which debuted in Pokemon X & Y.
The Pokemon Omega Ruby and Alpha Sapphire release date is November 21 in North America and Japan, and November 28 in Europe.
