Identifiers) robots to ZDR to investigate, but lose contact. The Federation sends Samus Aran to ZDR to investigate. Underground, Samus encounters a Chozo warrior, who destroys the exit, defeats her in combat and strips her suit of most of its abilities. Her ship's computer, Adam, instructs her to find another path to the surface and return to her ship. Samus is attacked by the EMMI, which have been reprogrammed. She escapes and absorbs a mysterious energy from one of the planet's central units. The energy temporarily enables the Omega Blaster, with which she destroys the EMMI and regains some of her abilities. In Ferenia, Samus is captured by another EMMI, but is saved by a Chozo named Quiet Robe, who deactivates them. Quiet Robe explains that, long ago, two Chozo tribes, the scientific Thoha and warrior Mawkin, banded together to trap the Metroids on the planet SR388. The Thoha intended to destroy SR388, but Raven Beak, the Mawkin leader, wanted to use the Metroids as a bioweapon to conquer the galaxy. He slaughtered the Thoha tribe and spared Quiet Robe so the Metroids could be controlled with his Thoha DNA. He planned to use ZDR to house Metroids, but had to contain an infestation of the X while Samus eradicated the Metroids from SR388. Raven Beak reprogrammed the EMMI robots and lured Samus to ZDR to extract the Metroid DNA implanted in her during the events of Fusion, which would allow him to revive the Metroids. Quiet Robe opens a barrier to allow Samus to progress before he is assassinated by one of Raven Beak's robotic soldiers. Adam encourages Samus to defeat Raven Beak and destroy ZDR. In Elun, Samus encounters the X parasites and inadvertently releases them into the rest of the planet. One of the X possesses Quiet Robe's corpse and reactivates the remaining EMMI. Samus arrives on the surface, where she is attacked by the last of the EMMI. She destroys it by sapping its energy with her hand, a power gained from her Metroid DNA. As a side effect, Samus is slowly becoming a Metroid. On the floating fortress of Itorash, Samus confronts Raven Beak, who has been masquerading as Adam. Raven Beak reveals that he spared her before so that she would awaken her Metroid powers, at which point he would clone her to create an army of the most powerful Metroid of all. Samus
