The Hadean Supervirus was the crown jewel of the Precambrian supereon. The first life to be born on Earth, the ferocious germs are 4 billion years old and come from much harsher times, from the Hadean eon when Earth was nothing more than molten rock. Thus they are extremely sturdy and adaptable using up their hosts in a matter of seconds and reducing them to dust. They appear only in The Official Game of The Movie where they clean up unclaimed carcasses that even the lowest of scavengers aren't interested in. The corpse rapidly decomposes in a matter of seconds as the microbes feast. They do not touch corpses that have been nibbled on as they do not care for impure or rotten flesh. Other Precambrian creatures can be located deep, deep down in the ocean surrounding the island.
