List of confirmed stages in Super Smash Bros. 4
The following is a list of stages that are known to be in Super Smash Bros. 4. Note that at the moment, most stages do not have confirmed names, and the names seen below are guesswork or placeholders unless the official names are cited.
Another incarnation of the Battlefield stage from previous Smash games. Similar to Brawl's Battlefield, it appears that the new Battlefield will feature a day-night cycle. While the stage appears in both versions, they both feature different designs.
Super Smash Bros. for Nintendo 3DS
A stage based on the arena from Fire Emblem: Awakening.
Players fight over the river in Gerudo Valley as seen in The Legend of Zelda: Ocarina of Time 3D. The Gerudo Valley track from The Legend of Zelda: Ocarina of Time can be heard during the Developer's Direct.
Players will fight on the Spirit Train from The Legend of Zelda: Spirit Tracks as it travels through New Hyrule. Toon Link appears to be driving the Spirit Train. The overworld theme for The Legend of Zelda: Spirit Tracks can be heard during the Developer's Direct.
Find Mii stage
Kid Icarus: Uprising stage
A stage with a backdrop that shows a cloudy sky with falling rain. A vast lake shown between to canyons in the background, with a castle in the foreground. According to the corresponding Miiverse post, this stage is from chapter 11 of Kid Icarus: Uprising, where humans are fighting over the publicized fake Wish Seed and get a Reset Bomb dropped on them. Other images of the stage show the Reset Bomb being dropped and the fight taking place inside the forest created by said Reset Bomb.
A stage that takes place inside a room set in the Nintendogs universe, with Nintendogs visible in the background. Characters are the size of toys. In the Developer Direct, the shower theme of Nintendogs could be heard during gameplay on this stage.
Super Mario 3D Land stage
A scrolling stage based on Super Mario 3D Land. The players fight through both an area resembling World 1-1 from said game as well as an area taking place on spinning platforms suspended above water and spiked pillars that destroy the platforms. There are also rolling blocks as platforms. The main theme for Super Mario 3D Land can heard during the Developer's Direct video.
Unnamed grassy area
A grassy area with a cobblestone wheel platform. It is not yet clearly identified what the stage is nor its origin.
Super Smash Bros. for Wii U
A stage based on the second area from Pikmin 3, the Garden of Hope. It appears to be a grounded stage with an uneven landscape. A platform with edges that can be grabbed, named the 'tin lift', hangs from above. It is based on the same kind of platform that can be found in the Garden of Hope in Pikmin 3. These platforms descend when supporting too much weight, but it is unknown if this happens in Super Smash Bros. The S.S. Drake sits in the background.
A stage set in the Super Mario Galaxy. Bowser's Airship and Starship Mario can be seen in the background. The stage has different gravity, so it calls for new tactics.
A stage based on the Pyrosphere area from Metroid: Other M, specifically the area that Samus Aran encounters Ridley. It features four platforms in a parallelogram shape, and Sakurai has stated on Miiverse; "An enemy from Samus's past may appear at any second…", possibly implying an enemy such as Ridley will appear as a stage hazard.
A stage on and around Skyloft from the The Legend of Zelda: Skyward Sword. Like Brawl's Delfino Plaza stage, Skyloft is a touring stage, that flies combatants to various parts of Skyloft using a set of moving platforms. Characters can fight in front of the bazaar, the Statue of the Goddess, the windmill topped by a bird's nest, the top of the Light Tower, among other locations.
A stage based on Windy Hill Zone, the first level from Sonic Lost World for the Wii U.
A stage based on the Pilotwings series. Combatants fight atop the wings of a biplane, based on the biplane of the original Pilotwings game, as it flies through the sky. Over the process of the battle, combatants will move from the biplane onto a yellow plane, based on its design in Pilotwings Resort. The plane flies towards Wuhu Island, the main location in Pilotwings Resort, as well as games such as Wii Fit and Wii Sports Resort.
Animal Crossing stage
A stage with elements based on the Animal Crossing series. There appear to be two variations of the stage, one set in the village and the other in the city. It's unclear if these are two separate stages or variants of the same.
Wii Fit stage
A stage that appears to be the room where Wii Fit Trainer does practices in the game Wii Fit. The stage features a large mirror in the background, as well as a living Wii Balance Board character, and a treadmill. Three floating Wii Balance Boards are the stage's aerial platforms.
A generic indoor stadium with a jumbotron. It is currently unclear if it is based on a specific game or if it is original to Super Smash Bros. 4.
