In addition to Metagross, Diancie and Sableye, all three starter Pokémon from Generation III will now have a Mega Evolution featured in Pokemon Omega Ruby and Pokemon Alpha Sapphire.
While we may already have seen Mega Blaziken in Pokemon X and Pokemon Y, this is the first time we get a closer look on the Mega Evolution of Sceptile and Swampert. As to what Mega Stones they use to involve has yet to be revealed.
Pokemon Omega Ruby and Pokemon Alpha Sapphire is scheduled to release for Nintendo 3DS on November 21 in North America and November 28 in Europe.
