Music was used extensively throughout Robot Wars. In addition to opening and closing themes, music was played in the background during battles, when robots were being introduced, when 'battleboards' (showing which robots were fighting each other next) were being shown, and in various other places. The music remained much the same for the first four series, with new music being produced when the series was revamped for The Fifth Wars and Extreme. This new soundtrack remained until the end of the original series. Many of the tracks were also used in merchandise and international versions of the show, with Nickelodeon Robot Wars being the only international series to have music specially produced. All music for the original series was composed by John Waddell and Will Parnell.
