Pokemon Omega Ruby & Alpha Sapphire video shows space battle between Rayquaza and Deoxys

A new story episode for Pokemon Omega Ruby and Alpha Sapphire has been shown in a new trailer for the game.

Called Episode Delta, it finds Deoxys and Rayquaza fighting it out in space, and trainers trying to stop Team Magma and Team Aqua from attacking the Mossdeep Space Center, a research facility, which is tracking an asteroid hurtling towards earth.

The episode will also shed more light on the Hoenn region, who holds the secret to stopping the asteroid, and the introduction of Zinnia, a "mysterious girl rumored to possess the key to the fate of the world."

The Episode Delta trailer is posted below and shows various legendary Pokemon which Siliconera says can be "found at Mirage Spots while soaring through the skies over Hoenn."

Pokemon Omega Ruby and Alpha Sapphire release next week on November 21 in North America and it will release the following week on November 28 in Europe.
