Pokémon X and Y is bringing a change to one of the most popular series' of all time by adding a new feature called "Mega Evolutions."
In the game's universe, players capture these Pokémon to train and battle against other opponents. In an RPG style of play, the stronger your Pokémon gets, the more it will level up. Once one of these creatures reaches a certain level, they evolve into a stronger form of themselves. Some Pokémon, however, require a certain stone or scenario to make them transform. In X and Y certain Pokémon will need a Mega Stone.
Nintendo revealed the new Mega Evolution features at the Pokémon World Championships this past weekend in a trailer showing off three characters new: Mega Ampharos, Mega Absol, and Mega Mawile.
Nintendo had previously announced Mega MewTwo, Mega Lucario, and Mega Blaziken.
Only select Pokémon will be able to transform into a "Mega" form, and will require their own significant Mega Stone.
According to the game company, these new mega evolved Pokémon will be much stronger in battle, although it is unknown how much more and in what ways.
Pokémon got its start in Japan in 1996 and then became a popular television cartoon show in 1997, according to the Anime News Network.
The game is scheduled for an Oct. 12 release on the 3DS.
