Eschervis

Eschervis are a parasitic protozoan species that reproduces inside the living cells of other beasts. These advanced biological weapons can dissolve their bodies into billions of infectious nanomonsters and reconstitute from host bodies, effectively transforming between a macroscopic monster and a microbial disease at will. When not inside an infected cell or in the process of infecting a cell, Eschervis exist as an independent, physical form known as their ''virion form. ''This form consists of a polygonal-shaped nucleic acid surrounded by a protective coat of capsid protein - this is where their DNA is stored - and long strains of tail fibers. However, some characteristics of individual Eschervis may depend on the species they have successfully infected or their overall strength.

Symptoms of Eschervis infection widely ranges from minor symptoms such as fatigue and coughing, to fatal - at fatal point, symptoms will include leakage of the Eschervis' nucleic acid through oral pathways.
