{{articleabout|Metroids, the parasitic bioforms|other uses|[[Metroid (disambiguation)]]}}

'''Metroids''' are parasitic, energy-siphoning lifeforms created by the [[Chozo]]. Metroids comprise bioengineered to combat an even more menacing parasitic organism native to SR388, the [[X Parasite|X]]. The [[Metroid (series)|''Metroid'' series]], named after these lifeforms, focuses primarily on the missions of [[Samus Aran]] and her interactions with the Metroids species, which share some elements of her own origins and seem intrinsically linked with her.

== History ==
[[file:Manga Volume 1 Chapter 4 Metroid.png|left|thumb|175px|The first Metroid is unveiled]]
The Metroids were first created through a collaboration between the [[Chozo]] and [[Mother Brain]] to combat a dangerous parasitic lifeform discovered on [[SR388]], called the [[X Parasite]]s, which the Chozo feared might one day infiltrate the [[Galactic Federation]].<ref>{{cite manga|Old Bird has confered extensively with Mother Brain, and they have devised a method to exterminate Parasite X from SR388, and we finally have a sample of that method. Metroid!!|Grey Voice|1|4|15}}</ref> They were so named because the word "Metroid" means ultimate warrior in Chozo.<ref name=history>{{Cite manual|While is has come to light in recent years that the Metroids were created by the ancient Chozo civilization, it is no common knowledge that they were created for the purpose of driving out the X parasites. At some point in the past, the X parasites, which posses a terrible propagation power, threatened to overwhelm the ecosystem of their home world SR388 with their vast numbers. Something was needed to check this impending disaster. That "something" came in the form of the Metroids. When the Metroids, the X parasites' only known predators, were made extinct by Samus's hand, the X parasites once again began to multiply with ferocious speed. Ironically, the X parasites were subsequently responsible for nearly killing Samus when they infested her Power Suit. In a further twist, Samus's life was saved by an injection of an experimental vaccine containing Metroid DNA. As the inheritor of the Metroids' powers, Samus becomes the only being capable of opposing the X parasite horde. In a piece of ancient Chozo literature, and interesting reference to Metroids was found. It seems that the word Metroid in the Chozo language can be roughly translated as "ultimate warrior." With the introduction of Metroid DNA to her system, the reborn Samus Aran is perhaps the most appropriate successor to this title of ultimate warrior.|Metroid Fusion|40}}</ref> They were so successful at hunting the X, they drove them close to extinction. At some point, the Metroids apparently grew feral, eventually topping the food chain on SR388 and devastating the local ecosystem.<ref>{{cite manga|"SR-388... This is a remote planet, not found on many Galactic charts. This is where the trouble began. Three months ago, the planet reclamation division reported an uncharted planet and a group was sent to survery the area... But the first thing they recorded was death... They estimated that 80% of the native animals were dead! Unfortunately, they were forced to report that they had been sent to a 'dead planet'... Among the reclamation group were special inspectors. And of course, they looked for the cause... but a terrible thing happened later. The culprit of the planet's destruction killed our inspection team as well!!" "Metroid!"|[[Chief Hardy]] and [[Samus Aran]]|2|14|6, 7}}</ref> They established their own life cycle, and may have even caused the Chozo to leave the planet.

===Zebes Incident===
:<small>''Main articles: [[Metroid (game)|Metroid]]/[[Metroid: Zero Mission]]''</small>
Later, the [[Galactic Federation]] discovered the Metroid on SR388, and several specimens were acquired for research. On the way back to headquarters, however, the Federation ship was ambushed by [[Space Pirate]]s. Recognizing the military potential, the Pirates took the Metroids to [[Zebes]].<ref>{{cite manual|In the year 20X5 of the Cosmic Calendar, a terrible incident occurred. The Space Pirates attacked a deep-space research vessel and seized capsules containing samples of an unknown species that had been discovered on planet SR388. The Space Pirates' objective was to acquire this life-form: known simply as Metroids, these floating organisms were incredibly dangerous, as they could latch onto any other organism and drain its life-energy. Furthermore, it was possible to replicate Metroids in vast numbers by exposing them to beta rays. The hypotheses that the Metroids were responsible for one of the greatest mysteries in the entire galaxy- the extinction of planet SR388- was generally accepted as fact.|Metroid: Zero Mission|6}}</ref> The Federation, in turn, ordered [[Samus Aran]] to eradicate all Metroids on Zebes, a mission that she completed during the events of ''[[Metroid (game)|Metroid]]'' and ''[[Metroid: Zero Mission]]''.<ref>{{cite manual|As a last resort, the Federation Police decided on a risky strategy: to send a lone space hunter to penetrate the pirate base and destroy the mechanical life-form that controlled the fortress and its defenses- the Mother Brain. The space hunter chosen for this mission was Samus Aran.|Metroid: Zero Mission|7}}</ref> Though Samus was successful in destroying the Metroid population and dismantling the Space Pirate operations on the planet, a number of Space Pirates escaped, taking a number of Metroids with them.

===Phazon Mutations===
:<small>''Main articles: [[Metroid Prime (series)|Metroid Prime Series]], [[Tallon Metroid]]</small>

[[File:Tallon Metroid 01.jpg|thumb|left|250px|A Tallon Metroid in captivity]]
After the fall of Zebes, two contingents of Space Pirates set out on separate missions: one to rebuild Zebes and resuscitate [[Mother Brain]], [[Ridley]], and [[Kraid]], and the other to find a suitable power source, which manifested itself in the [[Phazon]] emanating from [[Tallon IV]].<ref>{{cite manual|But the Space Pirates were far from finished. They immediately split their survivors into two camps. One remained on Zebes to begin rebuilding their ravaged facility and resuscitating Mother Brain, Ridley, and Kraid. The second set out in search of a planet with powerful energy resources. They didn't search long before they discovered Tallon IV, which was still emanating huge pulses of energy from the Phazon contained beneath the Chozo temple.|Metroid Prime|9}}</ref><ref>{{cite|Zebes has fallen. All ground personnel are presumed dead, either killed by the Hunter clad in metal or in the subsequent destruction of the underground facilities. Our research frigates Orpheon, Siriacus and Vol Paragom were in orbit at zero hour and managed to retreat. Frigate Orpheon is now docked at Vortex Outpost. Orpheon's cargo appears to have a 100% survival rate; Metroids are healthy but on restricted feeding schedules due to uncertain supply status. We are ready to begin research on the Metroids and other promising life-forms. Security status remains at Code Blue; no signs of pursuit from the Hunter.|[[Pirate Data]] "Fall of Zebes"|Metroid Prime}}</ref> Using Phazon's mutagenic properties, the Space Pirates began experimenting on local lifeforms and the Metroids they had brought with them, resulting in [[Tallon Metroid]]s. These Metroids differed somewhat from the originals created by the Chozo, and other mutated forms, including [[Hunter Metroid]]s and [[Fission Metroid]]s, were created.

[[File:Tallon Metroid (Aether).png|right|180px|A Tallon Metroid from Aether]]
In an unexpected twist, the [[Leviathan|meteor]] that originally infected Tallon IV with Phazon brought a Metroid with it from its [[Phaaze|homeworld]] as a guardian, though how or when Metroids were introduced to that planet remains a mystery. This drastically mutated Metroid, known as [[Metroid Prime (specimen)|Metroid Prime]], is engaged in battle by Samus after she overthrows the Space Pirate operations on the planet. Though she is victorious, Metroid Prime manages to survive and using some of her DNA is reborn as [[Dark Samus]].

The Space Pirates quickly set up Metroid breeding operations again, this time on planet [[Aether]], where [[Tallon Metroid]]s with red membranes and [[Infant Tallon Metroid]]s, as well as [[Dark Tallon Metroid]]s possessed by violent creatures known as [[Ing]], are encountered. Samus again intervenes and removes the Space Pirate and Metroid presence while battling the Metroid known as Dark Samus.

During the events of ''[[Metroid Prime 3: Corruption]]'', Samus finally engages in a final conflict with [[Dark Samus]] as well as several other Phazon-mutated variants of Metroids she encounters along the way. She destroys the living planet known as [[Phaaze]], and all Phazon in the galaxy is apparently eliminated, effectively exterminating all Phazon-mutated strains of Metroids.
{{clear}}

===Extermination on SR388===
:<small>''Main articles: [[Metroid II: Return of Samus]]/[[Metroid: Samus Returns]]</small>
Some time later, the Federation orders Samus to eradicate the Metroids on SR388, where the Chozo originally unleashed them. After destroying the Metroid population, which had developed several stages of maturity including [[Alpha Metroid]]s, [[Gamma Metroid]]s, [[Zeta Metroid]]s, and [[Omega Metroid]]s, and the ability to reproduce through egg-laying, she battled and destroyed the [[Queen Metroid]]. A single [[Metroid Hatchling|baby Metroid]] hatched shortly after the Queen was destroyed and mistook Samus for its mother. Samus decided to spare it and took it to Galactic Federation researchers at [[Ceres Space Colony]].<ref>{{cite manual|The Metroids on SR388 were more advanced than the creatures on Zebes. These monsters could shed their skins and grow even stronger. Samus worked deep below the surface and blasted all of the Metroids in her path. Her final victory was against the enormous Metroid Queen. When the queen was defeated, Samus discovered a Metroid egg which hatched before her eyes. Even this hardened bounty hunter could not destroy the Metroid larva. When the larva sensed Samus' presence, it clung to her as though it had found its mother. Samus packed up the Metroid larva and took it with her to the Space Science Academy on the Galactic Federation Space Colony where scientists could study the creature and understand its special organic structure.|Super Metroid|4}}</ref> In so doing, Samus unintentionally wiped out the only predator of the deadly X Parasites.

===Return to Zebes===
{{Main|Super Metroid}}
[[File:Baby and Ridley - Ceres.jpg|thumb|left|200px|Ridley steals the Hatchling]]
Research began immediately, and Federation scientists discovered that the energy-producing properties of Metroids could benefit humankind, suggesting that Metroids may have originally been created for peaceful purposes.<ref>{{cite manual|The Science Academy scientists found out that the energy-producing properties of the Metroid could benefit humankind. Their report suggested that the Metroids may have originally been created for peaceful purposes. Just when it seemed peace and order had been restored, Samus received an emergency directive from the Galactic Federation.|Super Metroid|5}}</ref> But shortly after Samus left the colony, it fell victim to a Space Pirate raid. Samus received their distress call and returned to the station, where she witnessed [[Ridley]] escaping with the Hatchling.<ref>{{cite manual|Emergency! Emergency! Return immediately to the Space Science Academy! When Samus made her way to the research facility, she found the building in ruins and the Metroid larva was nowhere to be found. Out from the darkness came a group of Zebesian space pirates and their leader, Ridley, who had the Metroid larva in tow. The pirates fled to a rebuilt planet Zebes and Samus followed them, resolving to finish them off and save the hatchling!|Super Metroid|5}}</ref> She pursued them to Zebes, where she entered the rebuilt Space Pirate labyrinth controlled by Mother Brain. Inside, Samus encountered early attempts by Space Pirates to create clones of Metroids, called [[Mochtroid]]s, but these were ultimately far weaker than the originals.

[[File:Baby attacking Samus.gif|thumb|right|200px|The Hatchling nearly kills Samus]]
After making her way into the new [[Tourian]], she destroyed the successfully cloned Metroids gathered there and eventually encountered the Hatchling, this time far larger. It drained Samus's energy, leaving it at critical levels, before recognizing her and leaving. Just as [[Mother Brain]] was about to kill Samus, however, the Hatchling returned and used its energy-producing abilities to transfer energy to Samus, recharging her. In that instant, the Hatchling was destroyed by Mother Brain, sacrificing itself to save Samus in this final act, perhaps demonstrating the beneficial abilities the scientists had discovered. With the Hatchling destroyed, it seemed the Metroid species was extinct. But unbeknownst to Samus, the Galactic Federation was clandestinely performing experiments on Metroids in captivity.
{{clear}}

===Federation Experimentation===
{{Main|Metroid: Other M}}
Following the events of ''[[Super Metroid]]'', Samus, still in mourning over the Hatchling, encounters a distress call from the Federation [[Bottle Ship]]. While aboard, Samus discovers that the Federation had created clones of dangerous lifeforms she had encountered for use as bioweapons using organic particles affixed to her [[Power Suit]], including Metroids. Suitable environments for these specimens were also created, including a replica of Tourian called [[Sector Zero]] where the Metroids were genetically engineered. The Federation also replicated an artificial intelligence to control the Metroids - a second Mother Brain. But the specimens became too aggressive and the project was endangered.

Though Samus is successful in her efforts to suppress the creatures they had created, including a [[Queen Metroid]], the situation gets out of hand and her commanding officer, [[Adam Malkovitch]], decides to separate Sector Zero from the rest of the Bottle Ship and initiate its self-destruct sequence. Later, the Federation orders the entire Bottle Ship destroyed and the self-destruct is initiated. But before its destruction, several tissue samples are salvaged to continue experimentation elsewhere.

===Presumed Extinction of Metroids===
{{Main|Metroid Fusion}}
[[file:Restrict Laboratory Metroids.png|thumb|right|200px|Metroids in the Secret Laboratories]]
Around this time the Federation hired [[Biologic Space Labs]] to study the restructuring ecosystem of SR388 and hired Samus to render field assistance in the harsh environment.<ref>{{cite manual|SR388. A vile planet, former home of the Metroids. After so many years, the remaining creatures on this planet still seemed to be trying to recreate a natural hierarchy, one without Metroids at the top.<br/>Biologic Space Labs was hired by the Federation to observe this restructuring of the ecosystem. And because of my experience on SR388, the Federation governor for this sector hired me to provide field assistance on the planet. So, once again I found myself drawn to that forsaken rock.|Metroid Fusion|8}}</ref> While Samus was on SR388, she was attacked by an X parasite, a lifeform previously unknown to the Federation and now rampant without the Metroid presence, that infected her. The Federation saved her life with a vaccine made from Metroid DNA that had been acquired from the Hatchling. It allowed her to absorb any free-floating X but also made her inherit the Metroids' vulnerability to extreme cold, turning her into a sort of a hybrid.<ref>{{cite manual|Someone proposed a desperate treatment: create a vaccine from Metroid cells. Apparently the Federation had preserved a cell culture from the last Metroid. The scientists quickly prepared and administered the vaccine. The symptoms of the infection disappeared instantly, and all of the X parasites within me died in moments.|Metroid Fusion|10}}</ref>

Samus begins the arduous task of eradicating the X population from the infested [[Biologic Space Labs Research Station|Biologic Space Labs research station]], which had housed many specimens from SR388 and remnants of the Bottle Ship experiments. As she progresses, she learns that the Federation had started a Metroid breeding program on board and has captive larval, Alpha, Gamma, and Zeta Metroids in their secret labs. Samus moves the station in the path of SR388 in an attempt to eradicate all X aboard the station, but before she could make it to her ship she was attacked by an enhanced Omega Metroid that was immune to all her weapons. Before the Metroid could finish Samus off, an [[SA-X|X copy of Samus]] attacked the Metroid but was quickly defeated. Samus then absorbed the defeated X, regaining her Ice Beam ability which she used to destroy the Omega Metroid.

Once the station impacted SR388, the remaining Metroids aboard the station were destroyed. With the Metroid population supposedly extinct, Samus, with Metroid DNA integrated into her genetic code, is the last Metroid - the last "ultimate warrior."

== Life Cycle ==
[[File:Metroid Life Cycle m2 Sprites.png|thumb|right| Various stages of Metroid growth as seen in ''[[Metroid II: Return of Samus]]'']]
Most encountered Metroids are in the adolescent stage, only in select circumstances can they undergo their natural life cycle. All forms in their natural life cycle are fought in ''Metroid II''. In ''Metroid Fusion'' Samus also sees most forms on the B.S.L research station in the [[Restricted Laboratory]].
