The Official Pokemon Channel has just announced another addition to the list of Mega Evolution Pokemon set to be seen in the upcoming titles on Nintendo 3DS and 2DS. 'Pokemon Omega Ruby & Alpha Sapphire' games will feature Mega Rayquaza among other already revealed Mega Evolutions.

In addition to the good news about the new Pokemon, an video trailer showcasing the evolution has been released. In the video, gamers and Pokemon fanatics can witness the new Mega Evolution utterly destroy a level 100 Swampert with just one blow.

Some of the other Pokemon that will be featured as Mega Evolution include Camerupt, Sharpedo and Gallade.

Beyond that, the Pokemon Company has recently gone ahead and confirmed the leaders of Team Magma and Team Aqua.

What's more is that through the release of Japanese trailers for 'Pokemon Omega Ruby' and 'Pokemon Alpha Sapphire', some fans have spotted that Maxie, Team Magma's leader, appeared to have a Key Stone in his glasses, while Archie, Team Aqua's leader, has a Key Stone in his necklace.

The developers confirmed through the official website of the game that the leaders are indeed carrying Key Stones.

Maxie's Key Stone is in his glasses, called his Mega Glasses, which are essential to the evolution of his Pokemon. Similarly, Archie has a Key Stone in his Mega Anchor that functions much like the Mega Glasses.

'Pokemon Omega Ruby' and 'Pokemon Alpha Sapphire' will be released on Nov. 21 in North America, Japan, and Australia, and on Nov. 28 in Europe.
