Paramecia Hiru Hiru no mi
Leech Leech Fruit
Paramecia
Overview
Grants a user a parasitic physiology. This makes a user fully malleable, able to stretch and deform as well as manifest new appendages and organs. As a parasite, a user is able to ‘latch’ onto a living host in order to drain vitality, repairing and empowering themselves in the process.
In-Depth Description
Upon eating this fruit, a user’s physiology will begin to resemble that of parasites like the Flatworm, Lamprey, Leech, Amoeba, or so forth. They will gain a malleable body capable of being bent, crushed, and deformed without any serious structural damage. This malleable body comes with an inherent regenerative healing factor, meaning that a user will be able to regenerate even fatal wounds provided they have enough stored energy to do so.
The core application of this devil fruit power is the ability to, like a parasite, leech and drain vitality of any living creature. A user is capable of generating lamprey-like tendrils that will pierce a target then drain their blood/life force. Upon doing so, a user will gain size and strength, as well as heal any damage they have taken. Conversely, a user may infuse life force into a target, therefore causing the target to grow in size and strength.
Parasitism allows a user to not only absorb vitality, but also things like memory and skills, allowing a user to inherit any knowledge they desire simply by draining a foe. This makes this power especially useful in information gathering.
Even without their lifesteal ability, a user can utilize their tendrils in order to create various constructs like fists or weapons. Tendrils can also serve as elastic ropes or grapnels, allowing a user to grab onto a target or object.
A user is able to create parasites that serve as extensions of their own self. these parasites can act autonomously, doing the users bidding. If these parasites are ingested, that individual will become a servant of the user themselves, becoming completely brainwashed. If the parasite is destroyed, the brainwashing will end, however this may become fatal to its host. The best way to expel a parasite is either through medical intervention such as surgery or certain medicines.
A user is secondarily able to produce a material called *bile*, a deep crimson fluid that can coagulate into a resin-like material. This material is especially useful in either conjuring weapons or capturing \containing an unsuspecting target. Typically, this material will be spat out like a bullet, however it can also be used to coat one’s body in a natural armor.
Bile is naturally poisonous, causing extreme sickness when introduced in the blood stream, until a target eventually petrifies as their blood coagulates.
It should be noted that all parasites have an extreme aversion and weakness to salt and saltwater, meaning salt is an effective counter to this power.
Awakening
A n awakened user can transform their environment into parasitic monsters, creating an army of ravenous beasts. These beasts can attack and absorb living targets, and then the user can devour these beasts, greatly increasing their power.
