The Pokemon Company recently revealed a few more details about the two new legendary creatures for Pokemon X and Y, Xerneas and Yveltal. Xerneas, the legendary being in Pokemon X, is a fairy type that has an exclusive Geomancy move. Yveltal, Pokemon Y's legendary beast, is a dark and flying type that uses the move Oblivion Wing.
Xerneas comes with the Fairy Aura ability, which strengthens fairy-type moves for all Pokemon in battle, whereas Yveltal's ability is Dark Aura, which does the same for dark-type moves. Pokemon X and Y are due out on October 12 for 3DS.
