3D Enhancement
Pokémon X Version and Pokémon Y Version are the first two Pokémon games that are completely in a 3-dimensional style of gameplay on a handheld system. Each and everything has been changed since the release of previous Pokemon games. The sprites have been changed into 3D designed models from the characters to the Pokémon. The appearance of a Pokémon has also not been changed as seen in the trailer when the male protagonist was running through the grass and encountered a Pikachu.

Battle System Enhancement
The battle system in video games also went under a 3-dimensional style. As seen in the trailer of the video game there were different Pokémon battles introduced. The attack of a Pokémon will be shown in a 3D style against another Pokémon. It will even show how the Pokémon will move when it's being attacked or vice versa by the opponent.

Starter Pokémon

 * Chespin, a Grass-type Pokémon: a brown, Erinaceidae-looking Pokémon with a spiked green hat, small arms and a small tail.
 * Fennekin, a Fire-type Pokémon: an orange, fox-looking Pokémon with flame-like fur emerging from its ears. Fennekin also shares its name and appearance with the Fennec Fox.
 * Froakie, a Water-type Pokémon: a blue, frog-looking Pokémon with a white puffball on its back.

The two legendary Pokémon that are the mascots for Pokémon X Version and Pokémon Y Version have been officially named as: Xerneas and Yveltal. Xerneas is deer-like with rainbow antlers, who is shaped like the letter X when it's legs are apart, while Yveltal bird-like avian of some sort, who is shaped like the letter Y.
