Mario Bros. (team)
- For the arcade game, see Mario (universe)#Mario Bros.. For the stage in Super Smash Bros. Brawl, see Mario Bros. (stage).
The Mario Bros. team also appears in Super Smash Bros. Melee in Adventure Mode. If the player has unlocked Luigi, they will fight Metal Mario and Metal Luigi instead of their regular forms. If Luigi has not been unlocked yet, then they will fight only Metal Mario. If the player manages to defeat both brothers, they will be rewarded the Metal Bros. KO bonus.
The Mario Bros. team does not appear as a team in Melee's Classic Mode (despite their frequent appearance on 1P Game in Super Smash Bros.) since the team battles in Classic Mode are chosen at random. They do not appear in any of Melee's 1 player modes (despite their usual appearance from Super Smash Bros.); Classic Mode or Adventure Mode. They do appear in event matches; Event 31: Mario Bros. Madness and Event 38: Super Mario Bros. 2 (with the addition of Peach).
They return in Super Smash Bros. Brawl on Classic Mode as a possible team opponent in the Mario universe stage (making it their usual appearance in 1P Game from Super Smash Bros.); which is on Stage 8 of Classic Mode. The player will be teamed up with either Peach or Bowser. They also appear in Event 19: Wario Bros. (where the player is Wario) and Co-Op Event 8: All MINE! (where P1 is Wario and P2 is Bowser).
In Super Smash Bros. for Wii U, the Mario Bros. are the characters the players play as in co-op events: A Lurking Menace and Wrecking Bros.. They also appear as opponents in the events: Family Ties and Solidarity.
In Super Smash Bros. Ultimate, the Mario Bros. are fought as a team in Donkey Kong's, Ganondorf's, Toon Link's (who are joined by Peach and Yoshi), and Pac-Man's (who are joined by Donkey Kong) Classic Mode routes. Only Donkey Kong and Toon Link are given allies (being Diddy Kong and a pair of Toon Links respectively) while the others do not have allies. Mr. Game & Watch also fights both Mario and Luigi in his Classic Mode route but as a Free-for-All rather than as a team. They also appear in MC Ballyhoo & Big Top's spirit battle along with Peach and Yoshi with all four fighters wearing their blue alternate costumes.
