Proto-Xenomorph

The Proto-Xenomorph (fan name) is a creature seen emerging from the dead body of a Mala'kak, bearing many resemblances to a Xenomorph. However, it possesses more human-like teeth, and has an erect bipedal posture. Its head shape is also unlike that of other Xenomorphs.

The egg which produced it is believed to have been injected by the tentacled creature, tentatively referred to as a Proto-Facehugger by fans.

The Proto-Alien does have resemblences to the Xenomorph. Its head is elongated but, ends in a point. It lacks a tail, and instead of a mouth-like tounge, it literally has anoother mouth within its' first one. However it does resemble the Xenomorph by its' reptilian and instect-like appearence and exoskeleton. It also stands up on two legs, like the Xenomorph can. The Proto-Alien is born fully-grown(possibly fully grown), it is not born as a worm-like creature but born into it's Xenomorph-like form. It completely bursts from the Space Jockey, not just from it's chest, but it's entire front side.

Nothing else is shown of this Proto-Alien, as of now we can only speculate it is an early stage of Xenomorph that under goes evolutionary changes to become the recognizable parisitic alien that is shown it the AVP universe.

As of the Proto-Facehugger, it is first shown as a fetus in Shaw's whomb. Therefore it is given birth to by a human, but is surgically removed before full growth and development. After Shaw leaves, she returns to see although she removed the creature it still grew to a giant mutant-like creature than has multiple legs and coloring that resembles a Facehugger. The Proto-Facehugger soon infects the Space Jockey with a tube-like organ that injects a egg/fetus through the Jockey's mouth. This is also behavior of a Facehugger. It even dies after infection like a Facehugger.

Again, with the Proto-Facehugger we can only speculate it is a early generagtion that is perfected by the Xenomorph evolution so that it is smaller and is born from a egg that is produced by a Queen Xenomorph.
