Part of Nintendo's presentation yesterday was a new trailer for the announced Gen 3 Pokemon remakes, Omega Ruby and Alpha Sapphire. As with X and Y, part of the trailer was devoted to new 'Mega Evolution' forms for certain Gen 3 Pokemon.
One of the fully evolved starters of these games, Blaziken, obviously has already gotten a Mega Evolution with X and Y that will be returning in these games. Similarly both Swampert and Sceptile will have their own Mega Evolution forms to use. Sceptile gains many new fern or palm leaf-like spikes, longer 'ears' as well as new red tipping to its arm leaves. Swampert on the other hand bulks up tremendously, it gains an extra head fin and its orange whiskers lengthen greatly. Mega Swampert retains its Water/Ground typing and has a new ability of 'Swift Swim', while Mega Sceptile gains the ability 'Lightning Rod' and becomes a dual-type Grass/Dragon.
As well it debuts a new form for each of the two Legendaries that appear on the box art, Kyogre and Groudon. Both forms bear resemblance to the 'Primal' form Dialga took in the second Mystery Dungeon series and appear on the front of Omega Ruby and Alpha Sapphire. They have been called Primal Kyogre and Primal Groudon.
One further Mega Evolution has been revealed, thanks to a scan from CoroCoro. Mega Diancie mega evolves from the Diancie pokemon and will be a Rock/Fairy type but as of right now, no information on Ability is known. The Mega Evolution gives Diancie more 'dress-like' frills, lengthens the 'ribbons' and changes the shape of the lace-like patch on its forehead slightly.
And today hot on the heels of the new information about the games, a video has gone up on the Official Pokemon Youtube channel that shows off the mega evolution sequence for Sableye - a Ghost-type introduced in the Ruby and Sapphire generation, the new form having been announced at the Nintendo's Kid Conference at E3.
The mega evolution is very subtle compared to other Mega Evolutions, the only changes seem to be red eyes, an extra head spike and a large jewel that Sableye uses as a shield. The large jewel shield is apparently the gem that used to be on the Pokemon's stomach area, and has absorbed most of the evolution's energy to swell and detach as a shield for the small imp-like Ghost Pokemon to hide behind. It doesn't seem as of this moment that the Mega Evolution changes Sableye's typing from its standard Ghost/Dark dual-type, nor is it known if it will gain a new ability.
These are the confirmed Mega Evolutions coming in the two new remake games. Nintendo have confirmed more are to come though, so we'll keep you updated when new Mega Evolutions appear!
