The end of the world (and the Protogen invasion?)

A protogen is an animalistic synthetic being with lifelike, but still synthetic tissue, bones and organs. On top of that, a protogen is identified by the visor they have that replaces their face. A protogen’s visor is made from “nanites.” These nanites act as a barrier for the visor’s systems, protecting it from the outside world. Nanites are able to move freely and reassemble their position, this allows a Protogen to open and close their mouth. When eating, a gap between the face and esophagus is made to allow nutrients to be digested. The visor itself cannot be removed as the internal barrier is holding essential blood & fluid. If cracked or damaged, the visor will have an almost immune system-like response and cluster to protect the internal barrier. Protogen may lose nanites through blunt force trauma, this may lead to cracks and gaps in the outer shell layer, but the internal layer will always be protected. If the internal layer of nanites is compromised, then it will usually lead to permanent damage and eventually death. Vision is artificially enhanced by the visor allowing the Protogen to have visual display overlays, thermal and other alternative optical abilities. The visor also allows scents to penetrate through a special set of Nanite receptors which carry the information to the brain. Nanites are not bound to any particular coloration or density, only that they have an outer and internal set to form proper functionality. Broken or depleted Nanites can be replaced. Protogens are several times stronger than the average adult and are capable of breaking a bone or cracking a skull with their bare hands. Protogens range from short to tall, from kind and sweet to ruthless and psychopathic. Protogen weaponry: Protogens are a spacefaring race with technology humanity has never dreamed of. They have various types of blaster weapons, from standard blasters to damn laser miniguns. World situation: The deadly Covid-19 virus, discovered in China in 2019, has spread massively throughout the world. It causes a high fever of up to 41 degrees Celsius, temporary loss of smell, and slight brain fog. sometimes has letal outcomes At the moment, there is no separate country in the world—Russia and its post-Soviet neighbors. There is the USSR, a dictatorship has been established, and Vladimir Vladimirovich Putin is president. Where he will lead the country is unknown. Scientists around the world are trying to create a creature that can help in the war against protogens.
