The "Bad Batch Theme" was co-composed by Deana and Sean Kiner and performed by the City of Prague Philharmonic Orchestra for the television series Star Wars: The Clone Warss seventh season. Initially released on February 21, 2020, the theme is played throughout that season and in Star Wars: The Bad Batch to represent Clone Force 99. It is also played during the end credits of the episodes of The Bad Batch, where it is followed by Omega's theme. Dave Filoni told Deana, Sean, and Kevin Kiner that Clone Force 99 were a group of misfits like those in The Dirty Dozen (1967), and so the composers watched the war films The Dirty Dozen, The Guns of Navarone (1961), and Kelly's Heroes (1970), and listened to their soundtracks. The composers then took the element of misfits from those films and incorporated it into the theme for The Bad Batch. The first bar of the Bad Batch Theme resembles the main theme of The Guns of Navarone, scored by composer Dimitri Tiomkin.
