"Samus Aran (サムス・アラン) is a fictional character and the protagonist of the Metroid video game series. Introduced in the 1986 video game Metroid, Samus is a female bounty hunter usually fitted with an armor suit with weapons that include beams and missiles. Throughout the series, she executes missions given to her by the Galactic Federation while hunting the antagonistic Space Pirates and their leader, Ridley, along with the energy-draining alien parasites called Metroids. Orphaned at a young age, Samus was brought up by the Chozo alien race, which trained her as a warrior. The Chozo also gave her the Power Suit, which features the ability to collapse Samus into a sphere to roll through tight areas such as tunnels."
