Pokemon X and Y Mega Evolutions Explanation and Overview

Mega Evolution is quite literally a game changer for Pokemon X and Y

When details about Pokemon X and Pokemon Y for the Nintendo 3DS began to trickle out, the new Mega Evolution feature quickly became one of the most talked-about details. These fourth evolutions can potentially throw a wrench into the battle plans of the most hardened veterans, making their addition a big deal.

But what is Mega Evolution, exactly? Which Pokemon in X and 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.

Mega Charizard X

Get Started With Mega Evolution

Mega Evolution is a power-up process that originated in the Pokemon X/Y 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 plan to exploit 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 won't be unlocked until you reach a certain point in the game's story.

How to Unlock Mega Evolution

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 have 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 win 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 to Get Mega Stones

Some Mega Stones are given to you automatically. Professor Sycamore, for example, gifts you with 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 with 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 the Lumiose City 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 finish the game at least once.

Pokemon Capable of Mega Evolution

Not every Pokemon is capable of Mega Evolution. Here's a list of the Pokemon capable of going beyond in X/Y:

  • Venusaur
  • Charizard
  • Blastoise
  • Alakazam
  • Gengar
  • Kangaskhan
  • Gyrados
  • Pinsir
  • Aerodactyl
  • Scizor
  • Ampharos
  • Mewtwo
  • Heracross
  • Houndoom
  • Blaziken
  • Tyranitar
  • Gardevoir
  • Aggron
  • Mawile
  • Manecrtric
  • Medicham
  • Banette
  • Garchomp
  • Absol
  • Lucario
  • Abomasnow

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 also reverts if it faints in battle.

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 gives you either Charizardite X or Y, depending on which version of the game you have. Likewise, Mewtwo will either hold onto Mewtwonite X or Y, according to your game version.

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 play Pokemon Y, you can't 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!
