When details about Pokemon X and Pokemon Y for the Nintendo 3DS began trickling onto the Internet, the new “Mega Evolution” quickly became one of the games’ most talked-about new features. These “fourth evolutions” can potentially throw a wrench into the battle plans of the most hardened Pokemon veteran, making their addition a big deal.
But what is Mega Evolution, exactly? Which Pokemon in X / Y are capable of receiving Mega Evolution’s gifts? What does the transformation process do besides make your Pokemon look a little cooler? Let’s break it down.
What is Mega Evolution?
Mega Evolution is a power-up process that originated in Pokemon X / Y’s Kalos region. Triggering Mega Evolution in battle allows certain Pokemon to temporarily evolve into a fourth form, making them considerably more powerful.
There’s more to Mega Evolution than giving Pokemon a little extra “oomph,” however. In some instances, Mega Evolution changes a Pokemon’s type, which can turn a battle on its head. For example, if a Charizard Mega Evolves into Mega Charizard X with the help of the Charizardnite X stone, that Charizard transforms from a Fire / Flying type to a Fire / Dragon type. If you planned on exploiting Charizard’s Flying weakness with a Pikachu’s Thunderbolt, you’ll need to rethink your strategy as quickly as possible.
A Pokemon needs its matching Mega Stone before it can evolve, and the process of Mega Evolution itself won’t be unlocked until you reach a certain point in the games’ story.
How Do I Unlock Mega Evolution?
Don’t worry—you won’t miss your opportunity! When you meet Korrina, the gym leader of Shalour City, she eventually asks you to meet her at the Tower of Mastery. There, she explains the secrets of Mega Evolution, and you’re given the opportunity to fight your rival (Serena or Calem, depending on whether your avatar is a boy or a girl) for the Mega Ring. The Mega Ring is a necessary component for Mega Evolution.
When you’ve won the battle for the Mega Ring, Korrina engages you in a fight that serves as a tutorial for Mega Evolution. When you win, she bequeaths you one of her Lucario, which is holding the Lucarionite Mega Stone.
Where Can I Get Mega Stones?
Some Mega Stones are given to you automatically. Professor Sycamore, for example, will gift you the Mega Stone for Venusaur, Charizard, or Blastoise when he gives you Bulbasaur, Charmander, or Squirtle.
Otherwise, most Mega Stones are acquired by talking to certain people, trading Pokemon amongst certain non-player characters (or with online players kind enough to send you a Pokemon holding a Mega Stone), or searching specific locations at night. You can also find some Mega Stones for sale at Lumiose City’s Stone Emporium. Stock shifts regularly, and beware – the stones aren’t cheap!
GamesRadar has a comprehensive guide on how to find all the Mega Stones. Keep in mind that some Mega Stones can only be found if you’ve finished the game at least once.
Which Pokemon are Capable of Mega Evolution?
Not every Pokemon is capable of Mega Evolution. Here’s a list of the Pokemon capable of going beyond the beyonds in X / Y:
Can a Pokemon Retain a Mega Evolved Form Outside Battle?
Pokemon can only Mega Evolve in battle, and only once per battle. Once the fight is over, the evolved Pokemon reverts to its normal state. The Pokemon will also revert if it faints in battle.
What’s the Deal with Mega Charizard X / Y and Mega Mewtwo X / Y?
Charizard and Mewtwo have not one, but two Mega Evolutions. These forms are known as Mega Charizard X or Y, and Mega Mewtwo X or Y.
How these Pokemon Mega Evolve depends on the version of the Mega Stone they’re holding. Professor Sycamore will give you either Charizardite X or Y depending on which version of the game you have. Likewise, Mewtwo will either be holding onto Mewtwonite X or Y according to your game version.
Can I Mega Evolve Mewtwo and Charizard into Mega Mewtwo X and Mega Charizard X even if I’m Playing Pokemon Y? How About Vice-Versa?
Both Mewtwo and Charizard can achieve their X or Y forms in either game, but you won’t find the opposite Mega Stone in-game. In other words, if you’re playing Pokemon Y, you won’t be able to Mega Evolve your Charizard into Mega Charizard X until you find an online player willing to part with their precious hunk of Charizardite X. Good luck!
