Metroids are feared parasitic organisms created by the Chozo, with the ability to leech the life energy from living organisms. As explained in the Metroid Manga, they were created in order to eliminate a more menacing parasitic organism native to SR388, the X. They have been the overall focus of the entire Metroid series in general. Metroids also appeared as Assist Trophies in Super Smash Bros. Brawl.
The Metroids were first created by the Chozo, apparently to combat the X Parasites. They were so successful at hunting the X, they drove them close to extinction. The Metroids grew feral, and became wild creatures that became the top of the food chain on SR388. They established their own life cycle, and may have caused the Chozo to leave the planet. The Chozo gave them their name because the word "Metroid" means ultimate warrior in Chozo.
The Galactic Federation discovered the Metroid on SR388, several specimens were acquired for research. On the way back to headquarters, the Federation ship was ambushed by Space Pirates. Recognizing the military potential, the Pirates took the Metroids to Zebes.
The Federation then ordered Samus Aran to eradicate all Metroids on Zebes, a mission that she accomplished. Some time later the Federation ordered Samus to eradicate every Metroid on SR388. After destroying every Metroid in her path, she battled and destroyed the Queen Metroid. Another Metroid hatched shortly after the Queen was destroyed, Samus spared it and took it to researchers at Ceres Space Colony.
Shortly after Samus left the colony, it fell victim to a Space Pirate raid. Receiving a distress signal, Samus returned to the station and witnessed Ridley escape with the Hatchling. Returning to Zebes, there Samus encounter failed clones of Metroids that were far weaker. 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. It reappeared again, just as Mother Brain was about to kill Samus and sacrificed itself to save her.
Later Samus was on a mission to SR388, where she was attacked by an X that infected her, the Federation saved her 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. Shortly afterward she learned that the Federation had a Metroid breeding program aboard the X-infested Biologic Space Labs research station. After moving the station in the path of SR388 in an attempt to eradicate all X aboard the station, before she could make it to her ship she was attacked by an Omega Metroid that was immune to all her weapons. Before the Metroid could finish Samus off, an X copy of Samus attacked the Metroid but was quickly defeated. Samus then absorbed the X regaining her Ice Beam ability that she used to destroy the Omega Metroid. After the station impacted SR388, the remaining Metroids aboard the station were destroyed. Samus is now the only remaining living life-form with Metroid DNA in her. However, the Galactic Federation could have harvested more DNA from the Metroid Hatchling Samus obtained on SR388. Or perhaps not all Metroids are exterminated on SR388.
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.
The most commonly encountered form of Metroids are the juveniles. Their bodies are covered by a thick, translucent membrane and four talon-shaped claws. The outer claws are used to grip their prey while the inner claws drain the energy. They are featured in Metroid, Metroid II, Super Metroid, and Metroid Fusion.

- "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 Instruction Booklet, Pg 40
- "Energy-based parasitic predator. The dominant species of planet SR388, Metroids can suck the life force out of living things. A Metroid will latch onto its prey and drain energy. growing larger as it does. The only way to shake an attached Metroid is to enter Morph Ball mode and lay a bomb." — Logbook entry (Metroid Prime)
- "A parasitic life form that can absorb all types of energy. Metroids have a strong resistance to most conventional weaponry. To defeat them, Samus Aran had to freeze them with Ice Beam shots and then blast them with Missiles. Mochtroids, which look like Metroids, are weaker, with fewer internal nuclei.

- "A bioengineered life-form found on planet SR388. Metroids attach to organisms and drain life energy. The Galactic Federation commissions Samus to eliminate them, but Space Pirates try to harness their power. One of the few ways Samus can kill Metroids is by shooting them with the Ice Beam and then shattering them with Missiles. The Metroid's cry is chilling and indescribable. * Metroid * Metroid II: Return of Samus" —Trophy Gallery (Super Smash Bros. Brawl)
