Nanites

Nanites are the microscopic machines that were created by the many international scientists during the in Abysus. At the time of the explosion five years ago, the nanites entered the atmosphere and spread across the globe.

Nanites exist within almost every living being, bonded to their molecular structure. Normally, nanites are completely harmless; however, when activated, they mutate the biology of their host, giving them grotesque physical features and/or special abilities. These are called E.V.O.s (Exponentially Variegated Organisms).
