It is rumored, according to some leaked images from the game, that the game will include Zygarde in all its five forms. Mega evolution, snake, dog, blob, and cell, all will be included in the game.
The rumor mill also suggests that Xerneas and Yveltal which were introduced in "Pokemon X," and "Pokemon Y" respectively, will also appear in "Pokemon Z." All these three characters are believed to be related to the Norse Mythology.
