Of all the new additions that came with Pokémon X and Y, mega stones have the potential to be the most exciting, as well as most interesting. Not only do they change certain pokémon's physical appearance, but also changes their type, abilities, and stats. Simply stated, it can completely change the tides during a battle. Provided you have one.
They also happen to be extremely rare. With the total number of pokémon close to 700, only about 30 are able to use Mega Stones, not even 5 percent. With technology changing not only the phyiscal appearances of the games, but also expanding the games' environments, you're probably going to have a bit of a tough time finding each Mega Stone.
Until now, at least.
We've provided the location of each and every stone in Pokémon X and Y, so if you want to turn your Charizard into a Mega Charaizard, you're in the right place. Keep in mind that some are exclusive to different versions of the game, and as others aren't found until later points in the game, potential spoilers lie ahead.
