Ex Nihilo (Earth-658)

Ex Nihilo is a Gardener, created by Aleph One to recreate whole planets.

Creatio Ex Nihilo
When the Builders became tired of fixing worlds, they put their efforts into creating 'teams' of artificial beings to do the recreation, so they could focus on destroying 'lost causes'. These teams were made up of an Abyss (An Exterminator, to infect the ecosystems), an Ex Nihil (A Gardener, to recreate the ecosystems with new designs) and an Aleph (Robots designed to judge the new ecosystem). Ex Nihilo was the first Ex Nihil, and worked with Aleph One and Abyss One. Ex Nihil's (And thus Ex Nihilo) were genetically coded so they matured to 'adulthood' in a matter of days, and from then on stopped altogether.
