Parasyte - Simulator

Note that even members of their own species cannot use male and female reproduction to create more parasites. According to human biology, the fetus would be born completely human, unless a parasite hosts its brain. There are also exceptional cases where the parasite fails to control its host's brain and therefore controls another area. This is considered a transgression and an offense by the parasites, a form of racism within their survival zone. Furthermore, each parasite is intelligent and can learn as it studies or trains in any specialty, just like a human being. They can also form clans or organizations among the parasites that host a single individual, with the goal of staking out territory and obtaining more human food.

Once they find a person:

• They usually enter through the nose, ear or mouth.

• They advance rapidly towards the brain.
  They destroy the human brain in a matter of seconds or minutes.

• They completely replace it.

From that moment on they control the entire body.
The original human dies during this process; what remains is the body controlled by the parasite.

Anatomy of a parasite. Although they appear to be simple worms at first, they are very advanced organisms.
They can:

• Completely change the shape of your cells.

• Turn the head into blades, hammers, tentacles, or spears.

• To harden your body as if it were steel.
  Repair damage quickly.

Analyze the environment and learn quickly.
When they are not transformed, the body appears completely human.

How are they born?
When the capsule opens:

• A very small, worm-like organism emerges.

• It has a kind of stinger or sharp point on its head.

• They move guided by instinct and do so at great speed, very difficult for the human eye to see them, they are about a centimeter long.
  Their sole objective is to find a suitable host.

• It doesn't need to eat before finding a human; all its energy is focused on invading a body.
