Virtua Fighter (universe)
Virtua Fighter (バーチャファイター, Virtua Fighter) is Sega's long-running series of fighting games, notable for inventing the 3D fighting game.
Though Virtua Fighter is never directly referred to within this game, Sonic's jab is based off the ubiquitous Sega punch-punch-kick jab combo from the series.
Virtua Fighter is represented in this game by downloadable content costumes for Mii Brawlers based on Akira Yuki, the main protagonist of the series, as he appears in the first Virtua Fighter game, and Jacky Bryant as he appears in the fifth game.
Two Mii costumes appear as DLC
Akira also appears as a spirit.
