Editing Mii Fighter (SSBU)

'''Mii Fighters''' ({{ja|Miiファイター|Mii Faitā}}, ''Mii Fighters'') are playable characters in ''[[Super Smash Bros. Ultimate]]''. They were confirmed as playable characters on June 12th, 2018 with their [[Mii Brawler (SSBU)|Brawler]], [[Mii Swordfighter (SSBU)|Swordfighter]], and [[Mii Gunner (SSBU)|Gunner]] variants returning. Unlike in ''Smash 4'', fully customizable Mii Fighters are now usable in [[online play]] against anybody in Quickplay, rather than just friends. The Brawler, Swordfighter and Gunner are classified as fighters #51, #52, and #53 respectively.

*{{change|On the [[character selection screen]], all three classes of Mii Fighter are listed separately instead of sharing a slot. However, this is not the case if the character selection screen is set to stacked mode.}}

Although no type of Mii Fighter appear in the World of Light opening cutscene, all three of them were vaporized and later imprisoned alongside the rest of the fighters (except for {{SSBU|Kirby}}) when Galeem unleashed his beams of light.

In the mode itself, each of the Miis can be found in different locations. In the Light Realm, the default Mii Swordfighter can be found in the small town square where [[List of spirits (Animal Crossing series)|Timmy and]] [[Master spirit|Tommy's]] is located, north-northeast of the first crossroads, and the default Mii Gunner is on the island that leads to the [[Forest Hill]].

The Mii Brawler is in the Dark Realm, and can only be unlocked in the [[Sacred Land]] sub-area after completing an optional time puzzle on the Triforce of Wisdom, which is hinted by an Owl Statue located in the Triforce of Power's section left path, by setting the time to 4:40.

Defeating a Mii Fighter automatically adds a default version of said Mii under the name Mii with a default 1111 moveset to the list of Mii Fighters for all modes where Mii Fighters are usable. These Miis cannot be restored if deleted.

*The announcer's voice clips for the individual Mii Fighter types are previously [[Unused content (SSB4)#Sounds|unused voice clips]] found in both versions of ''SSB4''{{'}}s data. This is also true of the "Round 1", "Round 2" and "Round 3" voice clips used in {{SSBU|Tourney}} mode.

*If they are counted as starter characters (due to them not having a Challenger Approaching fight), they are the only starter characters other than the starter characters from ''Smash 64''.

*Defeating the Mii Fighters in [[World of Light]] automatically adds the default Mii that was just defeated under the name "Mii" (with a default 1111 moveset) to the list of Mii Fighters, for all modes where Mii Fighters are usable. These characters can be deleted just like any other Mii Fighters, and there is no way to regain them if the player does so.

*Despite being captured during the story of World of Light and appearing in many spirit battles, none of the Mii Fighters are spawned by [[Galeem]] nor [[Dharkon]] as [[False character|puppet fighters]] during the final battle, presumably due to their nature as customizable characters.

*Though the Mii Fighters usually use their official renders throughout the game (albeit with their faces shadowed on the loading screens of Smash battles and online battles), they instead use models of the specific Mii Fighter in question posed like their official renders on the character select screen and on results screens (such as after a spirit battle), which reflects the actual appearance of the Mii Fighter.

*Unlike ''SSB4'', ''Ultimate'' has data for original Miis, like the Mii Fighters in World of Light. Information and instructions on how to recreate them are on the website [https://sites.google.com/view/miilibrary/NX/SmashUltimate Mii Library].
