Bounty hunter
Samus Aran explores the surface of the planet SR388 with a survey crew from Biologic Space Laboratories (BSL). She is attacked by
parasitic organisms known as X. On returning to the BSL station, Samus loses consciousness, and her ship crashes. The BSL ship she was escorting recovers her and transfers her to a
Galactic Federation hospital for medical treatment, where it is discovered the X infected Samus'
central nervous system. They cure her with a vaccine made from cells taken from the infant Metroid that Samus adopted on SR388. The vaccine gives her the ability to absorb the X
nuclei for nourishment, Portions of Samus's infected Power Suit are sent to the BSL station for examination, although the suit was too integrated with her body to remove entirely while unconscious. After Samus recovers, she is sent to investigate an explosion at the BSL station. The mission is overseen by her new gunship's computer, whom Samus nicknames "Adam" after her former
commanding officer, Adam Malkovich. and that the X have infected the station with the help of the
SA-X, an X parasite mimicking Samus at full power. Samus avoids the SA-X and explores the space station, She discovers a restricted lab containing Metroids, and the SA-X sets off the labs' auto-destruct sequence while attacking the released Metroids, who also devour the SA-X. Samus escapes, but the lab is destroyed. While escaping, Samus kills an X parasite mimicking
Ridley, and then arrives at the Sector 1 navigation room, where Adam orders Samus to leave the rest of the investigation to the Federation, which plans to capture SA-X for military purposes. This infuriates Samus, who knows that the X would infect the Federation troops and absorb their spacefaring knowledge to conquer the universe, and states her intention to destroy the station. Although the computer initially stops Samus by locking the doors in the navigation room, she then calls it "Adam", and reveals that Adam died saving her life. Adam gives in and recommends altering the station's
propulsion to crash into SR388, which would vaporize the X population. Samus realizes that the computer is the consciousness of Adam, uploaded after his death. En route to initiate the propulsion sequence, an SA-X confronts Samus, but she defeats it and sets the station on a collision course with SR388. As Samus prepares to leave, she is attacked by an Omega Metroid. The SA-X appears and attacks it, but is destroyed; Samus absorbs its nucleus and uses her newly restored Ice Beam to destroy the Omega Metroid. ==Development==
