Nathaniel Essex was a firm believer in Charles Darwin’s theory of natural selection, though he felt Darwin and his contemporaries were shackled by too many moral constraints to confirm it with human subjects. In his research, Essex learned that humanity has the potential to evolve due to what he called “Essex Factors” in the human genome. But he was labeled a quack by his peers and sought funding from unsavory groups and using the homeless as test subjects in his penny dreadful experiments. Eventually, Essex was telepathically contacted by who he would call Apocalypse for the revelations of the theory being proven. Under Apocalyse's instruction, Essex concocted a serum that would awaken his mutant gene. The result would be chalk white-skinned immortal that his dying wife would call "Sinister" in her final breath. When James Xavier learned of his experiments and informed the authorities, Sinister was forced to flee his homeland and go into hiding. Eventually emerging from the shadows ages later, Sinister seeks out ideal mutants to experiment on to help him make the world a much more evolved place: Targeting Scott Summer, Jean Grey, and their family as a result.
