Universe

A universe is a term used by the Smash Bros. community to collectively refer to all the particular characters, stages, items, music, and other properties appearing in the fighting games that are thematically featured in another game franchise.

Main universes

These are the video game series and franchises that the Super Smash Bros. games classify as major enough that they assign each franchise its own unique "universe symbol" that appears with characters and stages belonging to that franchise. These franchises generally have characters, stages, items, and other properties that all appear in Smash Bros. games as part of their primary content. However, the minimum requirement for a symbol is to contribute one character or stage to the games.

Universe	Symbol
The Super Smash Bros. universe: The "default" universe, this represents the Smash Bros. games themselves and accompanies all appearances of characters and stages that are thematically original to the fighting games themselves. Many original characters have been introduced here, but none thus far have been actually playable, with most serving as enemies and bosses in single-player content. The universe symbol seen here is also used as a "placeholder" by the games to indicate a minor universe without its own symbol. In Super Smash Bros. for Nintendo 3DS and Wii U, the Super Smash Bros. universe gets its own character representation by the Mii Fighter, but officially, they haven't been in any Smash game before their debut as playable in the Super Smash Bros. universe, not to mention that Miis have appeared in various other games, most notably the StreetPass Plaza games, including Find Mii.
Special Stages: The series that represents Battlefield and Final Destination on Melee (although Final Destination uses the Smash Bros. symbol, it is labelled under Special Stages). Not much is known about this universe, except that the Fighting Wire Frames, Master Hand, and Crazy Hand are always fought here (unless one executes the Name Entry glitch).
Subspace: A sort of sub-universe of the greater Smash Bros. universe, Subspace encompasses Tabuu and his Subspace Army, as well as the realm of Subspace itself and other original content restricted to the Subspace Emissary. Generator, Glice, Glire, Glunder, Mite, Poppant, and Roturret appear as enemies in Smash Run.
The Mario universe: Nintendo's flagship video game franchise. The company mascot at the head of this multi-genre series, Mario, is a primary playable character in Smash Bros. games, and has been accompanied by his brother, Luigi (both since Smash 64); his alter-ego, Dr. Mario (Melee, Smash 4 and Ultimate); the Mushroom Kingdom princess, Peach (since Melee), the villainous king of the Koopas, Bowser (since Melee) and his mischievous son Bowser Jr. (since Smash 4); the cosmic guardian, Rosalina, along with her child, Luma (since Smash 4); the Sarasaland Kingdom princess, Daisy (since Ultimate), the dinosaur, Yoshi (since Smash 64); the gorilla, Donkey Kong (since Smash 64), and his chimp nephew, Diddy Kong (since Brawl); the bellicose anti-hero, Wario (since Brawl), and the Piranha Plant (since Ultimate) are all characters from this franchise. The Mario universe is so expansive that Yoshi and Wario have been given their own sub-universes, while Donkey Kong and Mario started off together and therefore are linked in that way. Brawl also treats Mario Kart as a partially separate universe, containing two stages and a collection of music tracks, though it still uses the main Mario series symbol. Waluigi appears in every game as an Assist Trophy. A Chain Chomp appears in 3DS/Wii U as an Assist Trophy and an enemy in Smash Run. A Hammer Bro has appeared in every game as an Assist Trophy and is an enemy in Smash Run. A Lakitu and the Spiny appear in Brawl and 3DS/Wii U as an Assist Trophy and enemy in Smash Run. Banzai Bill, Bill Blaster, Bullet Bill, Flame Chomp, Giant Goomba, Goomba, Kamek, Koopa Paratroopa, Koopa Troopa, Shy Guy, and Spike Top all appear as enemies in Smash Run also. The Piranha Plant appears as a common enemy in Mushroom Kingdom (SSB) and will make an appear in Ultimate as a playable DLC fighter. Petey Piranha appears in the Subspace Emissary as the first boss. Toad appears as one of Peach's Special Moves. A Blue Toad also appears in one of Daisy's Special Moves. Stages include Peach's Castle, Mushroom Kingdom (SSB), Princess Peach's Castle, Rainbow Cruise, Mushroom Kingdom (SSBM), Mushroom Kingdom ||, Delfino Plaza, Mushroomy Kingdom, Mario Circuit (SSBB), Luigi's Mansion, Mario Bros., 3D Land, Golden Plains, Paper Mario, Rainbow Road, Mushroom Kingdom U, Mario Galaxy, Mario Circuit (SSBWU), Super Mario Maker, and New Donk City Hall.

The Yoshi universe: Referred to as the Yoshi's Island universe by PAL versions of Brawl, the Yoshi universe is based on the more colorful and saccharine subset of Mario video games starring the dinosaur Yoshi, who is the main (and thus far only) playable character of the series in the Smash Bros. games. Several properties seen in Smash Bros. games can be identified as strictly belonging to this universe instead of the Mario universe. Fly Guy appears as an enemy in Smash Run and an enemy in Yoshi's Island (SSBM). Stages include Yoshi's Island (SSB), Yoshi's Island (SSBM), Yoshi's Story, Yoshi's Island (SSBB), and Woolly World.

The games in this series are either platforming titles or (more prominently) micro-game collections, and Wario as he appears in both of these two genres of games within his series is the one playable character.

Secondary universes
