Greys

Greys, also known as Grey Drones, are genetically engineered humans grown in test tubes and modified with cybernetics to allow them to endure immense injury. First manufactured by the Monsoon Corporation in 2120, they gained freedom after The 1st Grey Emperor rebelled and caused the widespread usage of Grey Drones to be banned. Now most of them remaining Greys live under The Grey Empire. The few that do not are believed to be allied with The Prismarch.

Biology
A Grey's biology is very similar to a human, although there are a few major differences. The skin of a Grey is made up of an artificial organic polymer with an elasticity similar to that of human skin. The majority of their body is built around a cybernetic endoskeleton, meaning they have far more durable than normal humans. They do have a fatal flaw which is the bio-mechanical devices in their body are highly sensitive to electricity and electro-magnetism. Although some Greys have feminine or masculine bodies, they are incapable of reproduction and are asexual.
