X Parasite
From Wikitroid, the Metroid wiki
The X Parasite is a parasite witnessed only in Metroid Fusion. Mysterious, intelligent, and self-propogating organisms, the X were first encountered on SR388 as Samus Aran watched over a Biologic's Research team when the X parasite came out of the carcass of a dead Hornoad. The X infested Samus's central nervous system and rendered her unconcscious. Shortly after, Samus had to have various important parts of her Power Suit removed, some of them even surgically. After being infected, the X could not be removed from Samus's central nervous system, and she was given a very small chance of survival. Then, in a turn of luck, the Galactic Federation found a cell culture from the last infant Metroid and quickly injected it into Samus. Luckily, the X were completely and quickly destroyed by the infant Metroid's cells. Samus then gained the ability to absorb the X into her system. However, at the end of this adventure, Samus crashed the Biologic Space Laboratories research station into SR388 before evacuating, destroying both the space station and the planet and presumably wiping out the X.
X are capable of infecting other organisms and mimicking their prey's DNA and memories. One notable example is the SA-X. X parasites were in Samus's suit from her infection and was able to use the DNA in the suit to mimic Samus. At least ten SA-X with extreme destructive power were present on BSL.
Prior to the events of any Metroid game, the X Parasites were native to SR388. The Chozo discovered them, and, recognizing their destructive potential, created the Metroids in order to keep them at bay. This is first explained in the manual for Metroid Fusion, and later explained further in Volume 4 of the official Metroid Zero Mission Manga. Here, the Chozo refrain from telling the Galactic Federation of the X Parasites' existence, fearing that someone would view the parasite's abilities as a 'splendid technology' and use it for themselves. This fear is later realized in the events of Metroid Fusion. They also were the ones who named the organism and also stated that they could "borrow forms from their companions."
In Metroid II: Return of Samus, however, Samus wiped out all of the Metroids on SR388, allowing the X Parasites to make a recovery and return in Metroid Fusion.
