UNBEATABLE (stylized in either all caps or all-lowercase – “all caps or no caps” as their real-life creators put it) is a fictional rock band depicted in the 2025 American rhythm game of the same name. Consisting of vocalist Beat, guitarist Quaver, keyboardist Treble, and drummer Clef, the outfit serves as the game’s lead protagonists, fighting the fascist regime HARM and defying their zero-tolerance ban on music by playing underground shows.

Behind the scenes, UNBEATABLE is played by the members of Peak Divide and the D-CELL SOUND TEAM. Beat’s vocals are provided by her in-game voice actress, Rachel Lake.
