The next issue of CoroCoro is set to reveal a new feature for Pokemon X/Y, as well as a few new Pokemon. First off, Mega Evolution is set to possibly give existing final-stage Pokemon a new forme. The process isn’t clear as of yet, but Mega Evolutions have been confirmed for Blaziken, Absol, Mawile, Mewtwo, Lucario, and Ampharos. Pokemon who have “evolved” through this process will have a “Mega” preceeding their name (e.g. MegaBlaziken, MegaMewtwo, etc.). Additionally, it seems like the Mega formes of these Pokemon will gain a new special ability, as Mawile will gain Huge Power, Blaziken will have Speed Boost, Lucario will have Adaptability, and Absol will have Magic Bounce. Incidentally, it seems as if Mewtwo’s new forme is being classified as a Mega Evolution. Also, the Gym Leader Koruni has been reported to hold the secret to the process of Mega Evolution.
Next up are three new Pokemon. In the picture below, the first one on the left is the pre-evolution of Gogoat, named Meekuru. The one on the right is an Electric/Fairy type named Dedenne and can know either the ability Pick Up or Cheek Pouches (perhaps this is the new “Pikachu” for the generation?). The last one in the middle is Horubii, a normal type that can also know either Pick Up or Cheek Pouches.
