The perfect creature in the universe! Prometheus’ Alien Science Popularization

3. Facehugger

Face-hugging worm is the product of the hatching of alien eggs, with six legs and a slender tail, which is a bit like a spider with a tail. The face-hugging worm is short, fast-moving, and has amazing leg strength. Once the host is found, it suddenly jumps and falls on the surface of its respiratory organs, and its tail wraps around the host’s neck to make him unable to breathe and open his mouth. At this time, the face-hugging worm will implant the alien embryo into the host through the mouth. In order to ensure the life of the host, the face-hugging worm will provide oxygen to the host so that the host will not be suffocated. Acidic blood makes it have super protective function, making it difficult to peel off from the host’s head. Once the implantation is successful, the mission of the face-hugging worm is completed, and the surface rigidity falls off from the host and dies, or it can’t be called "death". The alien embryo is just beginning.

The alien queen can produce a special kind of egg to hatch the Queen Facehugger, which once appeared in Alien 3. However, the formation mechanism of this special face-hugging worm is still a mystery. According to the movie inference, it can be understood that the alien queen will produce this special egg only when her life is threatened, so as to continue the mission of alien reproduction.

4. Xenomorph-snail

The embryo implanted by the face-hugging worm parasitizes the host’s chest, absorbs the host’s nutrition to maintain life, and absorbs the host’s DNA to transform and improve its adaptability. At this time, the host can still survive, but the body will feel a little uncomfortable and sometimes it will be difficult to breathe.

5. Chestburster

Alien embryos will complete their own transformation and nutrient intake after growing at a certain stage, and they will leave the host, leading to the death of the host by breaking the chest. The process of breaking the chest is extremely tragic. Small aliens will burst the chest quickly, and flesh and blood will splash. Will the host die immediately? It will take a long time to die after struggling in severe pain.

The chest-breaker is like a snake, with only two front paws, which move by crawling. The head has the appearance of an adult alien, and he can bite his opponent with a sharp jawbone. But at this time, the chest-busters are still fragile and will try to avoid fighting. Their tiny size and rapid crawling will make them escape from the dangerous environment and hide.

6, adult alien (Xenomoprph)

After hiding, the chest-breaker will immediately develop into an adult alien, and will go through the process of molting on the way. Because the film does not show the development stage of the chest-breaker, it is temporarily understood that the chest-breaker-alien has only changed once during this period, and there is no evidence that the chest-breaker will take nutrition through eating, and only the eating plot has appeared in the game AVP.
