Among the features being added in the upcoming remakes of Pokémon Ruby and Sapphire are new Mega evolutions for three Pokémon, as well as new evolutions for the games’ two Legendary cover stars.

New information about the remakes, entitled Pokémon Omega Ruby and Pokémon Alpha Sapphire, has surfaced online from Japanese magazine CoroCoro. As translated by Serbii.net (via Siliconera), the games will feature three new Mega evolutions: two for existing Generation III Pokémon (Sceptile and Swampert) and one for a much newer Legendary Pokémon (Diancie). Mega Sceptile becomes a Grass/Dragon-type, while Mega Swampert remains a Water/Ground-type and Mega Diancie a Rock/Fairy-type. Mega evolutions are triggered in the game through the use of the Mega Bangle item.

The two Legendary Pokémon who serve as cover stars for Ruby/Sapphire and Omega Ruby/Alpha Sapphire, Groudon and Kyogre, respectively, will be getting new evolutions. Through something called “Ancient Devolution,” they will become (depending on the translation) Primal/Prehistoric/Primeval Groudon and Kyogre. Previously, neither had evolutions of any kind.

Confirmed to return in the remakes are the Mach Bike and Acro Bike, as well as Team Magma (led by Maxie) and Team Aqua (led by Archie). As was the case in the original games, which game you play will dictate which of the two you’ll encounter.

Nintendo announced Pokémon Omega Ruby and Alpha Sapphire last month. Both games are said to be “fresh takes” on the originals and are expected out on 3DS this November. You can count on them being on show during E3, which takes place this coming week.
