SR-388 is a planet that was visited by Samus Aran during Metroid II: Return of Samus and the very beginning of Metroid Fusion (the rest of the game takes place on BSL, which orbited the planet at the time of the game). The barren surface of SR-388 is notable for its rough, rocky and dry terrain. Dangerous gamma radiation constantly pounding the surface makes it diffucult for any species to habitate the overworld. Underneath SR-388's surface is a vast maze of tunnels and undergound rivers (not only of water, but of lava and acid also). SR-388 was the homeplanet to Metroid before Samus exterminated the race during the events of Metroid II: Return of Samus. It also is the home planet of the deadly X Parasite, which the Metroid were engineered by the Chozo to keep in check.
