The melody began as the main theme for Nintendo's Super Mario Bros. in 1985, composed by Koji Kondo, and it has since become one of the most recognised tunes in video games. Super Smash Bros., Nintendo's crossover fighting series, brings Mario and other Nintendo characters together, and its versions of the theme keep the original melody while giving it a fuller, more energetic arrangement. Shared in gameplay clips, edits and memes, the tune now works as shorthand for Nintendo nostalgia, friendly competition and a triumphant gaming moment.
