Pokemon X and Y have always surprised their players through new discoveries in the game. The latest of them is revealed to be a handful of Pokemon that is thought to be uncatchable. So players who already put away your Nintendo 3DS might want to reconsider their actions.
It was revealed by a hacker called Smealum, who spent his time going through the source code of the game and got a surprise awakening. He discovered three legendary Pokemon along with the mega-evolutions for Latios and Latias. Apparently, they are all unobtainable at the moment.
The Pokemon are known to be Diancie, a Fairy/Rock type, Volcanion, a Fire type and Hoopa, a Fairy/Ghost type. They will all probably be introduced in special events. If you are interested, below is a link where you can view screenshots of these Pokemon. If you don’t intend to spoil yourself with this, then stay away from the link.
