Confronted by Serba about the humans he cloned, Miles went completely insane and killed him, developing the personality of the Jackal as he tried to convince himself that someone else had killed his assistant rather than himself. Miles spent the following months refining the cloning process to successfully create clones who did not suffer from the tell-tale degeneration, which he ultimately accomplished, while also training his body and creating the equipment he would use as the Jackal to eventually confront Spider-Man.
