Parasytes are a more recent discovery. Initially, it was created illegally by scientists of a Team Rocket-style group which experimented on the corpse of an alien life form. The experiment, which took place on Rhine Island, resulted in the creation of a new Pokégirl type, the Parasyte. The experiment was broken up by members of the Shadow League, the scientists all being arrested. However, when they confronted the Parasyte, they became concerned and tried to kill it. The Parasyte possessed one of the male Tamers there and used his body to escape. He was eventually found again, but by that point he had been morphed into a female and completely bonded with the Parasyte. She voluntarily surrendered herself for study, but much later it was revealed she was covering for the offspring of the Parasyte that had initially bonded to her.

An unbonded Parasyte is an amorphous, black, liquid-like life form that shifts constantly. It has no real shape unless it bonds with a host, at which point it becomes a full-body, form-fitting suit that accentuates every curve of its host's body. It covers a host head to toe, although at the host's will, it can shapeshift into any type of clothing the user wants. It can take on any appearance the user wishes, looking even like a stylish superhero costume if the host wants, with parts of their body exposed to the air. It can also retract completely into the user’s body, as a Parasyte bonds with a host on a molecular level, and cannot be separated by force without causing severe harm to both the host and the Parasyte. If bonded with a male, it turns them into a female, in extremely rare occasions making them undergo threshold. If bonded with a Pokégirl, the Parasyte increases their abilities all around. The Parasyte is also a fully sentient being, and communicates with its host telepathically.

It's strange that this Pokégirl (and yes, it is a Pokégirl, believe it or not), is called a Parasyte, when actually it's more of a symbiotic life form. It enhances the overall abilities of a Pokégirl, grants them protection from psychic attacks due to the second mind enhancing the first, and in return it feeds off of the strong emotions and pheromones produced by it. (Interestingly enough, Parasytes seem to adore chocolate to the extreme, and will occasionally try to take control of their host to get some if they spot it. Rarely does this actually work, however, as they prefer to try and maintain some trust between themselves and their hosts.) Some could argue that the Parasytes are parasitic in that those who become bonded to a Parasyte become more prone to aggressive behavior, to rushing in without thinking. Some tamers site this as a benefit, however, as Parasyte-bonded Pokégirls also become more passionate and eager for Taming. This is especially prevalent if a Parasyte bonds to an ice-type, as they will seek the warmth of others to counteract the cold of their host. When a Pokégirl that is possessed by a Parasyte becomes Delta-bonded to a lover/Tamer, the Parasyte becomes Delta-bonded as well.

Parasytes share the weaknesses of their host, but their also have two special weaknesses. They have a pathological fear of flames, since it damages their liquid-like bodies severely. Some Parasytes even fly into a panic upon seeing flames and try to flee their host, always to no avail if they are completely bonded. This does not, however, mean that Parasytes cannot bond with Fire-type Pokégirls. They tend to avoid super hot girls like Magmammaries, or girls like CharAmandas, who have open flames on their body, but they can bond to fire-types, and thus lose their severe weakness to fire. Sonic attacks are also a severe weakness of Parasytes. Due to the nature of their bodies, a sonic attack can disrupt their physical structure severely.

Parasytes have some offensive capability of their own, but only when bonded to a host. They can morph their host's jaws into a large, saber-fanged mouth with a long, semi-extendable tongue that can secrete acidic drool. They can also morph the fingers of their host into long, dagger-like claws. These transformations are not permanent, and the host can shift their jaws and hands back and forth between their normal and monstrous forms at will using the Parasyte's abilities.

Parasytes don't reproduce normally. They spawn a new Parasyte by combining their DNA with that of their host and releasing a new Parasyte made from their own mass, which immediately sets out to find a host to bond with. Thresholding into a Parasyte is impossible, although they do enjoy sharing the feeling of a pregnancy with their host. A Parasyte is considered Feral only if it doesn't have a host. When it bonds with a Feral Pokégirl, it can help partially control their host's feral state by forming tentacles to pleasure the host with, simulating the effects that a human Tamer can provide. It won't completely solve the issue, but it will mostly clear the host's mind, allowing for more coherent, less-instinctual decisions.

Recently it has been discovered that there are some breeds of Pokégirl that a Parasyte flat out cannot possess. Legendaries have proven to be too powerful and too desiring of independence to be bonded with. If a host is already bonded to a Guyver, they cannot bond with her. (The same applies to a Guyver trying to bond with someone already bonded to a Parasyte.) And thankfully, Widows cannot be possessed by a Parasyte, as their bodies are too toxic and their minds too filled with rage and pain for a Parasyte to fully bond with them.
