The female parasite is about to cut off the man's head.

Despite these strong instincts, many parasites can ignore or outgrow their desire to eat humans. However, if a parasite does not take control of the brain of any species, it does not develop this instinctive cannibalistic hunger or violence. The parasite before it took over Nobuko Izumi.Īfter taking control of the brain of a human or an animal, parasites develop the instinct to kill and devour other members of their host species (parasites who took over humans desire to consume other humans, while those occupying dogs desire to consume other dogs), as well as destroy or devour parasites who didn't manage to take their host's brain but their other body parts. Parasites that are unable to take over a brain or end up in an animal host or any other part of the host's body are considered failures. Due to their instincts, most will be in the shape of a human head by default.Ī larval parasite instinctively aims for a human host's brain. They can morph into various shapes and extend and harden certain parts of their body as they desire. Parasites have skin resembling their host and insides to match, which can be changed as they desire.

The second stage is when the parasite finds its desired host and enters its body, maturing in a matter of minutes inside to become in sync with the host and replacing the body part it inhabits. The eggs or spores they emerge from resemble green airborne tennis balls filled with goo, or viruses. In the anime, they're small, approximately the length of a finger, while they are two or three times larger in the manga. The larval form resembles a green, almost translucent worm or snake with yellow eyes protruding out of its head, and a drill-like appendage on the front of its head. Parasites go through two main stages of development: a larval or primal form and a matured, humanlike form.
