Prism Tower is a stage appearing in Super Smash Bros. for Nintendo 3DS. The stage is set in Lumiose City of the Kalos region from the game Pokémon X and Y.
The stage begins on the streets in front of the tower's base in broad daylight. Later into the battle, moving platforms will appear and must be jumped onto to begin the ascent to the top. Near the top, the sun begins to set, and it is assumed that it will be full-out nighttime once at the top, (which will be available to stand and fight on). Sometimes Yveltal and Zapdos will appear in the background.
In Pokémon X and Y, Lumiose City is at the center of the Kalos region and is currently the largest city in the Pokémon world. It is home to Professor Sycamore, who gives the player one of the three Kanto starters at his lab, Bulbasaur, Charmander and Squirtle (earlier, he sends one of the three Kalos Pokémon to the player: Chespin, Fennekin and Froakie). It is also the location of several different cafes and restaurants, one of which is owned by Lysandre, the leader of Team Flare, and hides Lysandre Labs behind its walls. The Prism Tower, in Centrico Plaza, is actually the Lumiose Gym, where the player battles Clemont, an Electric-type specialist, for the fifth badge after solving a series of questions involving Pokémon.
