Nanites are microscopic machines that were created by the many international scientists during the Nanite Project 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, including plants and have bonded to their molecular structure in Rex's universe on earth. 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 EVOs which stands for Exponentially Variegated Organisms.
They appeared in the Ben 10-Generator Rex: Heroes United special.
