In the original ''Metroid'', Samus travels to the planet Zebes to stop the Space Pirates from using the Metroids to create biological weapons.<ref name="The History of Metroid, at GameSpot" /> She defeats the cybernetic lifeform Mother Brain, as well as Ridley and his fellow Space Pirate leader, Kraid.<ref name="timelines" />

The ''[[Metroid Prime]]'' series is set between ''Metroid'' and ''[[Metroid II: Return of Samus]]'', and chronicles Samus' conflicts with a malignant, radioactive substance named Phazon.<ref name=":4" /> In ''Metroid Prime'', Samus travels to Tallon IV to stop the Space Pirates from exploiting a Phazon-infused meteor that has poisoned the local ecosystem.<ref name="timelines" /> After battling a cybernetically enhanced Ridley and clearing out the Space Pirate presence on the planet, Samus purges the Phazon from Tallon IV by defeating the titular enemy, a Phazon-infected Metroid. ''Metroid Prime: Hunters'', which is unconnected to the Phazon storyline, sees Samus respond to a distress call to the Alimbic Cluster. Other bounty hunters respond to the call, and after conflicting amongst themselves, they all ultimately band together to fight against a creature named Gorea.<ref name=":4" /> In ''Metroid Prime 2: Echoes'', Samus explores the planet Aether, which is suffering from a Phazon outbreak. The Phazon has split the world into "light" and "dark" dimensions, leading to the rise of the evil Ing race. While liberating Aether from the Ing, Samus encounters Dark Samus, a revitalized Metroid Prime that has partially copied her physical appearance. In ''Metroid Prime 3: Corruption'', Samus and three other bounty hunters are recruited by the Federation to stop Dark Samus from infecting the galaxy with Phazon. While fighting to avoid being slowly corrupted by Phazon herself, Samus eradicates Phazon and her double.<ref name="timelines" /> ''Metroid Prime: Federation Force'', the only game in which players do not control Samus, sees Samus mind-controlled by Space Pirates; the Federation Force, an elite squadron of marines equipped with powerful exosuits, battles to rescue her and destroy the Space Pirates.<ref name=":4" />

In ''Metroid II'', the Galactic Federation calls for the extermination of the Metroid species and contracts Samus to travel to the species' homeworld, SR388, to carry out their extinction. She succeeds in wiping out the planet's Metroid population, but saves a single hatchling Metroid that bonds to her and delivers it to the Ceres research station for study.<ref name="timelines" /> In ''Super Metroid'', Ridley steals the hatchling and takes it to Zebes, where the Space Pirates are attempting to clone the Metroids. After killing Ridley, Samus herself is nearly killed by the revived Mother Brain, but is rescued by the now grown Metroid which sacrifices itself. Samus destroys Mother Brain in retaliation and escapes as Zebes explodes, exterminating her old enemies for good.<ref name=":4" />

In ''Metroid: Other M'', set after ''Super Metroid'', Samus investigates the Bottle Ship, a derelict scientific research station, with a Galactic Federation platoon led by her former commanding officer, Adam Malkovich.<ref name="timelines" /> They team up against many bioweapons created by a Federation science group, including clones of creatures Samus faced on Zebes like Ridley and the Metroids. A revived Mother Brain, now occupying a humanoid body supplied to her by the Federation, takes control of the Metroids and attempts to unleash them upon the Federation, but is stopped by Samus at the cost of Adam's life. Afterward, Samus encounters and kills the ethereal entity Phantoon and sets the Bottle Ship to self-destruct.<ref name=":4" /> In ''Metroid Fusion'', Samus accompanies a team of scientists to SR388, where she has her first encounter with the X parasites when the species reappears in the absence of the Metroids. The X overruns a scientific research station in the planet's orbit, assimilating and imitating many creatures being studied on board.<ref name="timelines" /> Samus is infected by one but is saved using a vaccine made from the baby Metroid's cells. She discovers that the Federation has been cloning Metroids in secret, and sets the space station on a collision with SR388 to destroy the X parasites.<ref name=":4" /> ''Metroid Dread'' continues where ''Fusion'' left off, with the Federation dispatching a squadron of advanced automatons known as E.M.M.I. to investigate the planet ZDR, where X parasites have been sighted. Samus is sent to the planet herself after contact is lost, coming into conflict with the X and a Chozo war criminal named Raven Beak, stopping both from invading the rest of the galaxy.
