The latest screenshot from the upcoming Wii U version of Super Smash Bros. teased the inclusion of Pokemon X and Y's Xerneas.

The screenshot was posted on the official Super Smash Bros site and featured Pikachu in the foreground while Xerneas was looking off towards the distance in the background.

Super Smash Bros. director Masahiro Sakurai took this screenshot during development and also posted it to the Super Smash Bros. Series community in Miiverse. What could he be hinting at here?

Whether or not Xerneas will show up as a playable character, an assist or simply a background character is still a mystery, but we'll let you know if more information regarding its appearance in the game, and whether or not it will be joined by Yveltal, is revealed.

Super Smash Bros. is set for release in 2014 for 3DS and Wii U.
