Like all previous Super Smash Bros. games, Super Smash Bros for Wii U has got a variety of stages, both old and new, upon which you can battle. These stages come from various different Nintendo franchises, including Pokémon, and each have unique features and hazards that are exclusive to them.
Each stage also has a special Ω (Omega) Mode which removes all the gimmicks from the stage and provides a simple platform on which to battle, akin to the Final Destination stage.
