Background
The X Parasite, also known as Unidentified Parasite Creature-X, is an extremely hostile, shape-shifting organism native to planet SR388. They are witnessed in the prequel manga, and make their resurgence in the post-credits scene of Metroid: Samus Returns. The X are later discovered and eradicated during the events of Metroid Fusion. They kill and assimilate other life forms in order to survive and spread; though simple-minded and entirely driven by instinct, they are in fact a threat to all natural life in the cosmos if left unchecked.
Their very existence is what drove the ancient Chozo race to create the titular and dreaded Metroid species with the intention of wiping out the X Parasite, therefore triggering most of the Metroid series' events.

Nothing notable.
Other
Standard Tactics: The X Parasite will attach itself to the host mimicking all of it’s abilities, powers, and adapting to whatever they throw at the X Parasite.
Weaknesses: The X Parasites have no notable counter to Metroids and their life force absorption, making the metroids the one counter to the X Parasites.
Note: While the X Parasites and Phazon beings never directly interacted on screen in the Metroid universe, the sheer threat level the X Parasites are treated as in the Metroid Universe should put their primary abilities at a 1-C potency, Samus Aran herself view the X Parasites as such a threat that she is willing to sacrifice her life to take out all X Parasites, with Samus being aware of phazon beings. Thus their abilities Reactive Adaptation, Power Mimicry, and Possession are believed to be on a 1-C level and that they can affect beings with a physiology akin to the Chozo Ghost.
