The Pokémon Company has shared new information regarding the Mega Evolutions in Pokémon X and Pokémon Y. Mega Evolutions are transformations that certain Pokémon can undergo during battles in the games. Additionally, once the battle ends, the Pokémon will return to its regular form.
An item required for Mega Evolutions is the Mega Stone. These are special stones that exist for all Pokémon that can Mega Evolve. Mega Stones are unique to each Pokémon, too—for example, Lucario uses the Lucarionite Mega Stone. Different Pokémon will see different effects from Mega Evolution. Mega Mewtwo and Mega Lucario will see their looks and stats increase. Others will change their abilities and element-type.
One Mega Stone in particular, Blazikenite, will not be found in Pokémon X and Pokémon Y. This stone will be made available via a special limited time Wi-Fi distribution, where you’ll get a Torchic holding a Blazikenite Mega Stone. The distribution will begin alongside the launch of the two games on October 12th.
