Super Smash Bros. is Nintendo's crossover fighting series, first released for the Nintendo 64 in 1999, in which characters from different franchises battle in arena matches. A distinctive announcer voice introduces each bout and calls out fighters, becoming one of the series' most recognisable audio signatures across later entries on GameCube, Wii, Wii U and Switch. Clips of the voice spread through gameplay videos, montages and memes, where creators reuse it to stage their own match-ups. Its familiarity and dramatic delivery keep it popular for introductions long after its debut.
