They invade a host body and absorb the {{wp|DNA}} and memories of the host before attaching itself to the creature's nervous system and killing it, enabling the parasite to mimic its appearance. The only known creatures able to combat the X are the artificial [[Metroid (species)|Metroid]]s and [[Samus Aran]].  

The simplicity in appearance and shape of the X is extremely misleading. Aside from being extremely fatal and quick to multiply, these creatures exhibit signs of an impressive intelligence and even the ability to communicate.

Curiously, the X appear to be able to communicate with one another across large distances. This is shown by the Blue X; though they originally attacked Samus while she was vulnerable to them, once she absorbs a couple using the [[Varia Suit]], the remaining X will flee from Samus on sight. Adam hypothesized that the X may have used the memories of a [[human]] through Human Core-X to destroy the research station for the mere purpose of defeating Samus, perhaps for the safety of X elsewhere in the universe.<ref>{{cite|The X mimicked a crew member... It all makes sense now. The X can absorb the memories and knowledge of their prey. What an astounding find. HQ was very impressed. But don't you find it strange? This could have destroyed the station with the X in it, not to mention to SA-X. Unusual for a self-preserving species like the X. Unless... Your presence is an even greater threat, a threat to the existence of X elsewhere... This is only a hypothesis... Perhaps... Their survival instinct is in conflict with their newly-borrowed intelligence... Don't let your guard down yet. The X are still a threat. Samus, I see bio-signs on the Habitation Deck. Survivors? The infected crewman you saw had survived until recently. Maybe there's a chance... The signs emanate from here.|Adam Malkovich|Metroid Fusion}}</ref>

The [[Metroid (manga)|''Metroid'' manga]] reveals that the [[Chozo]] first discovered and named the X on SR388. A camera placed by the Chozo revealed the Xs' destructive nature as one mimicked a [[Hornoad]]. In order to combat the X, the Chozo experimented on creating a biological weapon. These weapons would become the Metroids. The Chozo eventually released the destructive Metroids into SR388's environment, where they became the X's predators. Though they succeeded in creating a check to the X's growth, they also created a very malleable species, ready to be exploited by the [[Space Pirate]]s and the [[Galactic Federation]] alike.

While serving as a bodyguard for researchers of B.S.L. on planet SR388, Samus is infected by an X mimicking a [[Hornoad]]. Unknown by Samus, the X multiplied rapidly in her nervous system, and during her return to B.S.L, Samus lost consciousness. Just before her [[Samus Aran's Gunship|Gunship]] crashes into an asteroid belt, the security system automatically ejects Samus in an escape pod, which is recovered by a B.S.L. Research Station vessel.

Samus is taken back to [[Galactic Federation]] HQ to be treated. Because large portions of her [[Power Suit]] are infested by X, and because these portions are integrated with her nervous system, they have to be surgically removed. The X remain in Samus's central nervous system, and an experimental anti-X vaccine, [[Vaccine "Metroid"]], made from a cell culture from the [[Metroid Hatchling]] is used to cure her. As a result, all of the X in Samus are destroyed, and Samus becomes immune to future X infection and gains the ability to absorb other X-Parasites, using their energy to replenish her health and weapons. However, she also inherits the Metroids' weakness to cold as an unexpected side effect of the vaccine.

X-infected life forms from SR388 and the infected portions of Samus's Power Suit are transported to B.S.L for research, where the X run rampant through the station's six sectors, partly due to Samus's lifts on the security locks. The infected parts of Samus's suit became SA-X, a mimicked form of Samus. With this creature and the various other powerful specimens in the Xs' arsenal, the X managed to cause severe damage throughout the research station.

===Yellow X===

Yellow X are by far the most common form of X. They heal a measly ten units of energy. These X can be released by any mimicked species in nearly any condition. It was a Yellow X that initially infected Samus on [[SR388]].

There also exist a series of Core-X with a more durable shell and the ability to fire beams known as [[Core-X#Hard Core-X|Hard Core-X]]. These X are Core-X that have absorbed one of Samus's beam abilities. They have an "eye" which they use to shoot their beam with. Their shells cannot be destroyed by Samus's Missiles, she must instead fire into the eye to destroy it.
