Xenomorph (Canon, Composite)/ZeroTwo64

Summary
The Xenomorph XX121, better known just as Xenomorph or the Alien, is an extraterrestrial endoparasitoid species with multiple life cycles, possibly originating from the planet Proteus (also known as Xenomorph Prime). One of the deadliest of all known alien species, these creatures require a host organism in order to reproduce. The appearance of the Xenomorph can vary depending on the host in which the Facehugger implants. The Queen of this species is generally twice as large and possess superior speed, strength and intelligence than their offspring.

Attack Potency: At least Multi-City Block Level (Praetorians can challenge the strongest Predators, whose Plasmacasters are this powerful), possibly Universe Level to Universe Level+ (In the "Superman VS Aliens" comic series, Xenomorphs are able to harm Superman, whom is weakened because he doesn't have the yellow sun's rays to power him; however, if we consider the gap between the Low 2-C/3-A tier and the previous tiers, we know that Superman is still univeral to universal+ because he isn't infinitely weaker than his normal form and can still use most of his greatest powers. In "Mindhunter", there is a Xenomorph who is born within The Darkness via Darkling, and as such, holds its powers, making it Universal+)

Speed: At least Subsonic (Xenomorphs are fast to be recorded on camera), likely MFTL+ to Infinite (Can keep up with Superman), possibly Omnipresent (Equal to The Darkness)

Lifting Strength: At least Peak Human (Gridalien, a Xenomorph Drone, was able to lift Chopper, a Yautja, whose weight should be higher than 227 Kg due to its heavy youngblood armor), likely Class 50 (The Ryushi Xenomorph Queen was able to heave several tons of space truck off of herself)

Striking Strength: At least Multi-City Block Class, possibly Universal to Universal+

Durability: At least Multi-City Block Level (Can take fully charged Plasmacaster shots), possibly Universe Level to Universe Level+  (Can take hits from Superman. In "Mindhunter", there is a Xenomorph who holds the the powers of The Darkness, whom was able to survive the destruction of the universe without being damaged)

Stamina: Very High (Can hunt their prey for several days without food and without getting tired), possibly Limitless (Equal to The Darkness)

Range: Extended melee range, possibly Universal+

Standard Equipment: None notable

Intelligence: Gifted (Despite most Xenomorphs have shown to have an intelligence similar to primates, there are some cases in which they have shown to be very clever. They are able to communicate using telepathy and can cause nightmares and religious visions to their hosts, so Xenomorphs can be released from them and can lead to the formation of cults with the Xenomorph as a god-like figure. Thanks to the experiment conducted on Ellen Ripley, Xenomorphs are able to read and understand different languages. They are also very creative and clever in combat: they can move quickly and silently in ventilation systems and can use them for ambush or escape. Xenomorphs are conscious of the effect of their acidic blood and will use it to kill humans or break their weapons), possibly Nigh-Omniscient (Equal to The Darkness)

Weaknesses: Xenomorphs are very vulnerable to heat and fire, and the best way to defeat them is to take advantage of these factors. Predalien is the only species which isn't vulnerable to fire but it shows pain to high temperature. The alien queen is extremely vulnerable to fire.

Notable Attacks/Techniques:
 * Jaw: The Xenomorphs' primary weapon is their inner pharyngeal jaw, which is capable of shooting from their mouth like a piston with sufficient power to smash through bone and metal. In fact, a common tactic used by the creatures to eliminate prey is to restrain the victim with their hands, immobilizing them, before killing them with a precision jaw strike to the head, piercing through the skull and penetrating the brain; this form of attack is colloquially known as a "Headbite".
 * Acid Blood: Xenomorph blood is an extremely potent and concentrated molecular acid that can corrode on contact almost any substance with alarming speed. It is dull yellowish-green in color, and seems to be pressurized inside the body so that it spurts out when wounded, as a defensive measure. This blood can prove incredibly problematic when encountering Xenomorphs aboard a starship, as using traditional firearms or explosives to attack the creature will potentially cause its blood to leak out in sufficient quantity to eat through the hull of the ship.
 * Semi-Dexterous Tail: The tails have been shown grasping prey and used as spears or flails.
 * Wall Climbing: Aliens have proven to be adept wall climbers, whether that is a result of digging into surfaces with their claws, finding hand-holds, or through some adhesive effect such as those used by geckos or insects has not been demonstrated.
