Director Masahiro Sakurai has recently revealed that the Prism Tower in Lumiose City will be a playable stage in Super Smash Bros. for Nintendo 3DS/Wii U. Several screenshots of the stage were also shown in the Director's Room of the Super Smash Bros. community on MiiVerse.
The game is scheduled to be released this year and would be playable on both Wii U and Nintendo 3DS. Pikachu and Lucario will once again make a returning appearance to the game.
Lumiose City is a city that made its first appearance in Pokémon X and Y and is based on the city of Paris. Prism Tower is also the location of the Lumiose Gym in Pokémon X and Y.
