Master Beef hails from a cattle farm, and always had a tough time in the world, unlike his schoolmate Mario, who was naturally lucky and fit even though he was overweight. Master Beef in contrast, was very fit but Mario was still better at everything than he was, and always got the girls as well. Angry at this, Master Beef became rivals with Mario until the current point. Master Beef is revealed to have been off-screen in most Mario games, such as when he tried to rescue Peach in Super Mario Bros., but ultimately failed. His failures as well as lack of camera time eventually led him to challenge Mario for Peachy's love in Master Beef. Vs. Mario.
