Universe

A universe is a term first used by the Smash Bros. community, as well the Smash Flash community, to collectively refer to all the particular characters, stages, items 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 Flash games classify as major enough that they assign each franchise its own unique "universe icon or symbol" (they only appear in Super Smash Flash 2) 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 Flash. games as part of their primary content. However, the minimum requirement for an icon is to contribute one stage or one character to the games.

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.
