Fighters listed by their number on the Super Smash Bros. Ultimate website.

Fighter numbers are a method of identifying and sorting characters in Super Smash Bros. Ultimate.

Definition

As explained by Masahiro Sakurai, the numbers order characters based on "the order in which they joined the series". They are ordered in the following way:

  • SSB (01-12): The starter characters are ordered by their placement on the character selection screen, which in turn is based on each character's first appearance (with Mario and Donkey Kong as the oldest and Pikachu as the newest). The unlockable characters are similar, though they are sorted column-first rather than row-first as the starters are; as such, Ness precedes Captain Falcon despite being created later. This also matches their series debut order, explaining why Ness comes before Captain Falcon.
  • Melee (13-26): The starter characters are ordered by their first appearance on Melee’s E3 2001 reveal trailer (based on which ones had their faces shown first, meaning that the Ice Climbers and Sheik come before Zelda, whose hand appeared earlier in the opening). Zelda was the only character on Melee’s starting roster who wasn’t revealed to be playable at E3 2001, which could also be the reason why Zelda is placed after Sheik, despite Melee treating her as the primary character and Sheik as an alternate form. The unlockable characters are ordered by how many Vs. Mode matches are required to unlock them, and thus Young Link, Ganondorf, Pichu, and Mewtwo's roles in the reveal trailer are ignored.
  • Brawl (27-44): The characters first revealed in Brawl’s original trailer are ordered first, followed by the remaining newcomers in the order revealed on the official website. Notably, Pokémon Trainer is not given a fighter number, likely due to not being directly controlled by the player. Instead, the three Pokémon (Squirtle, Ivysaur, and Charizard, ordered by evolution stage) are given numbers.
  • SSB4 (45-63) and Ultimate (64-80): The characters are ordered by when each newcomer was revealed. While Pyra and Mythra share a character slot, they are given separate numbers as they are mechanically different, like Zelda and Sheik before them until Brawl.
  • Echo Fighters share their number with their "parent" in addition to an apostrophe (') stylistically referred to as "dash" in Japanese and Chinese or a superscript epsilon (ε) in other languages, regardless of which game they joined in.

Usage

The Fighter numbers are used to order characters on Ultimate's character selection screen and promotional material. Mii Fighters are instead shown as the last characters on the selection screen, likely due to their customizable nature. The only major in-game usage of the fighter numbers is that Echo Fighters, due to not having their own fighter number, can be optionally stacked onto the character they are based on in the character selection screens for Vs. Mode, Special Smash (except for Smashdown), Tourney, and Online modes (except for Quickplay).

A similar system is used for ordering stages on Ultimate's selection screen, where all stages are ordered by when they first joined the series (with the exception of stages shared between both versions of Super Smash Bros. 4, which are mixed in with stages from exclusively Super Smash Bros. for Wii U).
