Rundas is the theme for the battle against the boss of the same name in Metroid Prime 3: Corruption. The track utilizes synthesizers and vocals in its composition. A remixed version is used as the theme of the Metroid Prime Trilogy. The trailer for Trilogy uses Rundas' theme for its portion containing Corruption footage. The song itself was a remix of Emperor Ing Spider from Metroid Prime 2: Echoes. The song has vocalizations delivered in a somber manner alongside powerful percussions and guitar strings, representing how Samus is ultimately forced to fight her comrade Rundas due to the latter undergoing at the very least terminal Phazon corruption.
Prior to the battle, Rundas also has his own theme music, which is heard in all of his appearances up until the point where he attacks Samus, upon which his battle music is played instead. On the UK Corruption website, it is known as Track_4 in the music player. Rundas is the only Bounty Hunter in the game besides Samus Aran and Dark Samus to have a differently-sounding battle theme and entrance theme.
