Reiter

​Appearance
Reiters have a deciptively innocent look. Normally resembling flying, tattered and bloodstained rags about the size of a palm, it is hard to believe that these are S-class Grimm capable of levelling cities. The "bloodstain" pulses with red light, resembling a heartbeat.

​Abilities
Reiters are parasitic in nature, and without a host are almost trivially easy to kill, with a well placed round or strike killing them. If one manages to attach itself to a human/faunus, it with scurry over to their back and burrow through any present cloth or armor, before penetrating the spine. The host with be left paralysed for upto 24 hours, only able to feel soul-rending pain as the Grimm integrates itself through their nervous, muscular, skeletal and circulatory systems.

Afterwards, the Grimm will have total control over the newly procured body, and will use it to hunt and eat other humans/faunus. The host's sclerae will turn black, and their voice will become dissonant and bestial. Physical attributes like strength and speed are boosted to levels beyond even trained hunters, as specimens have been seen outspeeding trains and demolishing buildings with ease.

However, the Reiter's greatest weapon is a substance it produces, referred to as "Soulblood", viscous black liquid that pulses with red light much like the Reiter itself. While its origin is heavily debated, the most feasible theory is that it is processed from the bodies and Aura of those it devours. It can be rapidly shaped into any form by the Reiter, and some are shown to be able to convert it into bursts of force, torrents of flame and even lightning. Solidified Soulblood's physical parameters like hardness, density, flexibility etc. can be changed by the Reiter. It does not vapourise after the Reiter is killed.

The Soulbood can be fashioned into many shapes like tendrils, shields, wings, extra appendages, simple weapons and hardened crystals that can be fired like bullets. In addition to all of this, the Reiter has a potent healing factor. Some specimens have regenerated entire limbs and vital organs, and at least one has been documented healing from horizontal bisection within minutes.

​Weaknesses
Younger Reiters that are yet to devour enough people to become sentient can easily be ambushed or distracted long enough to escape.

Heavy firepower, such as anti-aircraft shells, can destroy the Reiter befor it can heal.

At their root, hosts are simply superpowered, animated corpses. Removing or destroying the controlling Reiter (which is normally encased with heavy armor) will also kill them.

The Reiter's healing factor has a limit. If all else fails, hitting it over and over until it dies is a good strategy as any.

​Trivia
"Reiter" means "Horseback Rider" in german.

It is inspired from Parasytes from "Parasyte: The Maxim". The hosts' abilities and Soulblood functions are taken from Ghouls from "Tokyo Ghoul".
