In the latest Pokémon X/Y news, it has been revealed that Mewtwo can Mega Evolve into either Mega Mewtwo X or Mega Mewtwo Y, depending on which Mega Stone Mewtwo holds (Mewtwonite X or Mewtwonite Y). The previously announced Mega Mewtwo is in fact Mega Mewtwo Y; Mega Mewtwo X is being introduced for the first time today. Players can obtain Mewtwonite X in Pokémon X and Mega Evolve Mewtwo into Mega Mewtwo X, which gains the Fighting type to go along with its Psychic type. Players can Mega Evolve Mewtwo into Mega Mewtwo Y, whose Special Attack is greatly boosted, by obtaining Mewtwonite Y in Pokémon Y.
An already powerful Dragon- and Ground-type Pokémon, Garchomp, can Mega Evolve into Mega Garchomp in Pokémon X and Pokémon Y. The increased energy released by its Mega Evolution turns Mega Garchomp’s arms into huge blades that send out a furious attack. Mega Garchomp’s Attack and Special Attack are greatly increased after it Mega Evolves, so its Dragon-type move Dragon Claw becomes extra ferocious.
Since the reveal earlier this year, Pokémon fans have debated which first partner Pokémon—Chespin, Fennekin, or Froakie—they are going to choose in Pokémon X/Y. Players are now getting a first look at their evolved forms, featured in a new gameplay trailer released today on Pokemon.com/XY. Check out this mind-blowing (if you're into that kind of thing) trailer!
