Metroid (NES)

In the year 20X5, the first Metroid was discovered on the planet SR388. The Zebesian Space Pirates abducted the Metroid specimen with the intention of using it as a powerful weapon, and thus our heroine, Samus Aran, was sent to the planet Zebes to foil their evil plans and save the galaxy from the wrath of the Metroid.

Metroid Prime (GameCube)

After her victory on the surface of Zebes, Samus learns of another Zebesian outpost in orbit around the planet Tallon IV. She discovers that the evil Space Pirate organization is also researching another lethal biotechnology known as "Phazon," and thus sets out to single-handedly bring down their terrorist efforts.

Metroid Prime Hunters (DS)

Six bounty hunters, including Samus Aran, travel to the Alimbic Cluster to investigate a telepathic signal promising the "ultimate power". This was a ruse created by the creature Gorea who was imprisoned by the Alimbics. The bounty hunters fight and defeat Gorea but return empty handed.

Metroid Prime III: Corruption (Wii)

Metroid II: Return of Samus (GB)

The Federation cannot rest until all Metroids have been exterminated, thus Samus is sent to their homeworld, SR388, to wipe them out for good. In her final battle on SR388, Samus witnessed the birth of a Metroid hatchling. As a result, the creature bonded with Samus and adopted her as its mother. Samus decided it best to return this infant -- the last known Metroid in the universe -- to the Federation for future research.

Super Metroid (SNES)

The last Metroid was in captivity. The galaxy was at peace...until... The Space Pirates, led by the ferocious Ridley, attacked the Metroid research facility and stole the specimen, returning it to the planet Zebes. Samus returned to Zebes in an attempt to rescue the Metroid, but in the final battle, the creature selflessly gave its life so that Samus could defeat the evil Zebesian leader, Mother Brain, once and for all. The last Metroid was lost, and the Space Pirates were defeated.

Metroid: Other M (Wii)

Metroid Fusion (GBA)

With the loss of all Metroid life, the planet SR388 began suffering from a severely unbalanced ecosystem. The Federation chartered the Biological Space Labs (B.S.L.) organization to oversee the reconstruction of this ecosystem on SR388, and, due to her vast experience with the planet, Samus Aran was contracted as an expert advisor on the project.

During a routine planetary expedition, Samus came into contact with an unknown organism on the surface of SR388. Although interesting, the encounter was never considered to be a threat. Later, while escorting the B.S.L. convoy in her ship, Samus lost control of her craft as her body was gripped by an intense seizure, and nearly died in the resulting crash.

B.S.L. scientists recovered Samus' jettisoned escape pod and designated the unknown parasite from SR388 that had infected her body as simply "X." The X parasite had infected Samus' central nervous system severely, and due to the integrated, biological nature of her suit, the infected parts of Samus' metal exoskeleton were surgically removed. Her prognosis for survival was slim.

A risky cure was proposed, and the team of scientists took the gamble and attempted to save Samus' life. Apparently, the Metroid is the natural predator of the X organism on SR388, thus a vaccine created from a surviving Metroid cell culture was injected to fight the remaining traces of the X parasite within her body. This predatory relationship has allowed the Metroid vaccine to both cure Samus and grant her immunity to all X parasite attacks. In fact, Samus is now able to regenerate her energy levels simply by absorbing these otherwise lethal X parasites.

The Metroid hatchling had saved her life once again. As Samus awoke from her comatose state, a distress signal was already being received from the B.S.L. space station in orbit around SR388. Samus wasted no time in boarding her ship and plotting a course to investigate...
