- For the arcade game, see Mario Bros.. For the stage in Super Smash Bros. Brawl, see Mario Bros. (stage).
The team consists of Mario and Luigi and are battled on Peach's Castle. The player and a random character must defeat both Mario and Luigi in order to proceed to the next stage. The Mario Bros. team also appears in Super Smash Brothers 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 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 Super Smash Bros. Melee's Classic Mode since the team battles are chosen at random. They also appear in Brawl as a random team in the Mario series battle of Classic Mode.
