In addition, they trained her in combat by equipping her with one of their artifacts, the Power Suit. To preserve her life and ensure that her status as the 'Protector of the Galaxy' would come to pass, the Chozo infused their DNA within Samus, which granted her superhuman athleticism and a strong resistance to foreign environments. The orphaned Samus was then found by a bird-like alien race known as the Chozo, who brought her to their home planet, Zebes. She was born and raised on the Earth mining colony K-2L, and when she was a child, the planet was raided by Space Pirates led by Ridley in an attack that killed her parents and destroyed the colony.
The Metroid e-manga covers Samus's origins.
