fabius bile

Fabius Bile, also called the "Clone Lord," the "Primogenitor," the "Manflayer" and "the Spider," is a Chaos Space Marine Apothecary and Chaos Lord, originally the Chief Apothecary of the Emperor's Children Legion, who has repeatedly attempted to use his extensive knowledge of cloning and genetic engineering to create superhuman beings under his control.

The goal of his quest for knowledge is to match and then exceed the Emperor of Mankind's original scientific achievement in creating the primarchs and the transhuman Adeptus Astartes, in the hope of creating a truly perfect human form.
