"Lavos's Theme" is a track composed by Yasunori Mitsuda for the game Chrono Trigger. It is the fourth track on the second disk from the original soundtrack. The song serves as the theme song for the intergalactic parasite, Lavos. First heard in the subterranean rooms of the Arris Dome when the party first views the Lithosphere Investigation Report on the giant computer, the track plays when the Hit Points of all party members reaches zero and a "Game Over" screen caption appears. Additionally, the song plays when the party battles Lavos. The pseudo-organ sounds denote an air of evilness, chaos, and impending doom.
