A series symbol is a distinctive iconography that represents another game universe, assigned to fighters and stages. For fighters, it is displayed next to a character's damage meter (in the same color as the player's slot), as well as on the victory screen. For stages, it is visible on the stage selection screen.
To an extent, these symbols are also applicable for items (as seen on the Smash Bros. DOJO!! pages), trophies (as seen in Super Smash Bros. 4's trophy collections), music (as seen in the sound tests from Brawl onward, as well as music previews on the Smash 4 and Ultimate official websites), and spirits (displayed while creating a party and within the Spirit List); however, these generally require a fighter representative in order to have a symbol assigned. Otherwise, the Smash Bros. logo or ellipsis symbol is assigned by default, or else no symbol appears at all. While some series have a symbol due to being represented by stages, if the universe isn't represented by a fighter the symbol will not be used outside of the stage.
The following is a list of all series symbols, along with a short explanation of what they are and where they come from within their game universes.
