Pseugrot

Pseugrots are a parasitic species that utilizes the corpses of beasts as a host. Because their bodies are rather immobile and vulnerable to most everything, they must infiltrate a host for protection - they can reanimate any beast, but favor mammalian carnivores.The Pseugrot will selectively manipulate and disable aspects of their host to their own convenience. Pseugrots use the body of their host to provide a home and means of cover.

It enters the host via mouth or any other cavities available on the body, however an in-tact body is preferred. As it makes its way inside, it will consume the creature's main tract of organs until there is ample space to reside in.

Appearance
Outside of a host body, Pseugrots are very soft, amorphous, worm-like creatures. Their bodies are covered in cilia, which is used to anchor themselves to the host body's musculature for ample control. Their faces come in a variety of looks, and are always starkly colored in comparison to the rest of their body.
 * Concealed: The Pseugrot's head and/or other extremities remain entirely inside of its host, only to reveal itself when absolutely necessary.
 * Reclusive: The Pseugrot remains relatively concealed, but spends most of its time peeking from its host.
 * Revealing: The Pseugrot has little to no concern for concealing itself.
 * Mutualistic: The Pseugrot preserves the host's entire brain. Shared bodily control varies per Pseugrot while both mutually "benefit" from each other.

Abilities
However usually rendered relatively brain-dead by the Pseugrot, the host will be kept alive by the Pseugrot replacing all organ function.The Pseugrot may take the liberty of changing things about their host's body to improve function and comfort.

False limbs: If the host's limbs are damaged beyond reconstruction or just inconvenient to the Pseugrot, they will be removed and replaced by the Pseugrot's own generated limb.These limbs will always look hand-like, but can vary in length and width.

Expansion: A Pseugrot may expand its main body outside of the host, usually to accommodate for lack of space inside of the host.

Reconstruction: If the host's body becomes superficially damaged, the Pseugrot is capable of generating itself outward to repair muscle and skin tissue.
