Pirate Homeworld is a theme in Metroid Prime 3: Corruption and is one of the songs available for purchase in the Soundtrack Gallery. On the UK Corruption website, it is known as Track_10 in the music player. This theme is heard in Pirate Command.
It is a remix of Crateria - The Space Pirates Appear (クレテリア 宇宙海賊出現) in Super Metroid, which is heard when Samus is ambushed by Zebesians in the ruined Zebesian Command Center, and nearly all of the west part of Crateria after this sequence. It will also play in the east caverns if Samus enters them from Maridia, despite the complete lack of Pirates there. This theme is included on the Super Metroid: Sound in Action CD as an arranged version, which includes Planet Zebes - Arrival on Crateria, another Super Metroid track.
Two different variations are heard during Metroid: Zero Mission, when Zero Suit Samus is forced to escape Zebes through Chozodia and the Space Pirate Mother Ship. The former version plays during the stealth sequences while the latter version plays when Zebesians spot her and is included as number 20 in the Sound Test.
The original theme has been performed in orchestra twice; first by the Tokyo Symphony Orchestra in 1994 as part of a medley (which arranges The Space Pirates Appear in a more lighthearted manner), and then in 2013 by the WDR Radio Orchestra as part of Into Red, Into Dark.
