Is the protagonist of the Metroid video game series. Introduced in the 1986 video game Metroid, Samus is an ex-Galactic Federation soldier turned bounty hunter, usually fitted with a powered armour 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 extraterrestrial parasites called Metroids. Orphaned at a young age, Samus was brought up by the extraterrestrial avianoid Chozo race, who trained her as a warrior. The Chozo infused her with their blood in order to create a perfect warrior, and also gave her the Power Suit. The suit gives Samus the ability to transform herself into a sphere called the Morph Ball in order to roll through tight areas such as tunnels.
