At the end of the movie "Prometheus", only one alien-like guy was born.

Alien is a complete series. In addition to the Alien prequel, there is also Alien 1 2 3 4

"Prometheus" is actually the prequel to Alien. The alien's reproductive ability is amazing and its reproduction speed is amazing. Pretty fast. In the prequel, there are many oval-shaped sealed tanks leaking black liquid, and each tank contains many primitive alien protozoans in their original form. These canisters were leaked, and this scene was included in the movie, so there were so many aliens in the first film.

What is an alien?

In the "Alien" tetralogy, the audience learned about the alien, a terrifying creature with thick acid blood and sharp teeth, and the race's complete and complex social system like an ant colony, which became the most important thing in human history. A nightmare from which one can never wake up. In "Prometheus", the audience's attention is drawn back to the time when the alien was born, and we can see the initial form of the alien.

1. Protozoa

The alien protozoa is a deadly biological weapon created by the "Space Jockey" race and is used to destroy mankind. The protozoa are stored in a cylindrical petri dish and are just a black liquid. The protozoa are very sensitive to the surrounding environment. Any slight environmental change can trigger the protozoa in the petri dish, causing the protozoa to leak. Once an organism comes into contact with the protozoa, it will cause infection, which will make the organism rigid and have extremely strong growth ability. And become aggressive. Due to the optimized DNA selection characteristics of protozoa, when protozoa attach to an organism, their structure will mutate and take on the form of the host. In "Prometheus", the protozoa first infect worms in the soil, turning them into snake-like creatures with highly acidic blood.

2. Protozoan embryo

Subsequently, the protozoan infected Field, turning him into a zombie-like creature, and was killed by the crew. Halloway was not spared after drinking wine containing the protozoa. After having sex with Elizabeth, the latter carried the protozoa's embryo. Since Elizabeth did not have direct contact with the protozoa, she was not a host but was cultivated in the womb. The protozoa's embryo The appearance does not have a human shape at this time, but looks like an octopus. If you look closely, you will find that they are actually "six-clawed fish". The setting comes from the shape of the facehugger in the alien queen's egg. Moreover, the DNA of the protozoal embryo was optimized to carry the female gene.

3. The birth of the Alien Queen

When the protozoal embryo takes the Engineer as its host and bursts out of its body, we can see that this creature has chosen the Engineer's space suit. From the appearance, it can be understood that the engineer's spacesuit has the characteristics of integrating with the body and has the characteristics of genetic selection, just like the nano armor in "Crysis 2", which integrates with the human body. That black solid appearance, coupled with female genes, is how the alien queen familiar to the audience in "Alien 2" was born.

It can be said that the engineer created the protozoa, which is just a tiny genetic body without a form. Just like a virus, it infects different species and makes them zombies and become aggressive, but because Elizabeth's female genes and the Engineer's body structure gave rise to a new species - the Alien.

The setting of "DNA optimization selection" strengthens the terrifying nature of the alien creature. It is not only a hunter with a terrifying appearance and sharp teeth, but also the agile movement in "Alien 3" The alien dog and the New-born that were combined with human embryos in "Alien 4" are all the result of this choice.
