Phendrana Battle is a music theme in Metroid Prime. It is heard in the later explored areas of the Phendrana Drifts that lead up to the Gravity Suit. It is much more upbeat than the previous Phendrana Drifts theme, but contains some notes from that theme.

It is also included on the Metroid Prime & Fusion Original Soundtracks, titled Ice Valley (Phendrana Deep Lake Area) (アイスバレイ（フェンドラナ地底湖エリア）).
