During a battle, using this new method of evolution, a Pokémon can Mega Evolve into a completely different appearance. Oftentimes, doing so will change that Pokémon's Abilities, Statistics, and even changing the typing of the Pokémon that Mega Evolves.
The method utilized for Mega Evolution is via the use of the Mega Ring or Mega Bangle which is used in conjunction with an item called a Mega Stone. Certain Pokemon will have its own Mega Stone, for example Blaziken will use a Blazikenite to evolve into Mega Blaziken. Each Pokémon will have their own mega stone in order to achieve Mega Evolution.
