HISTORY: Before being referred to as the creator of the most controversial character in the Spider-Man universe (Ben Reilly, a.k.a. The Clone), Professor Miles Warren (a.k.a the Jackal) was originally a shy and unassuming biology teacher at Empire State University. Both Peter and then girlfriend Gwen Stacy attended his biology class and Warren began to be quite taken with the beautiful Gwen, although the feelings were only avuncular in nature. However, Warren completely lost his marbles when Gwen died unexpectedly in what was undoubtedly the greatest comic story of all time.

RECAP:The Green Goblin had held Gwen hostage atop the George Washington Bridge in hopes to draw Spider-Man’s attention. When the latter arrived, a battle ensued and in a moment of total mayhem, the Green Goblin threw Gwen off the bridge. Although Spider-Man managed to catch her with a web line, the stop was too sudden and it snapped her neck like a twig. Peter Parker's first love was dead.

Before he began assuming the guise of the Jackal, Warren was approached by the mysterious being known as Scrier, who offered some assistance with his secret human cloning experiment. The latter agreed and immediately proposed that Gwen Stacy be the first human to be cloned, as he had obtained in the past cell samples from all of his former students. However, Scrier suggested that Peter Parker should be the first human to be cloned. When Warren’s lab assistant caught on to the fact that he was growing human clones, he threatened to expose him. Furious, Warren killed the innocent man. Feeling remorse for his wrongdoings, Warren became mentally ill and began believing that he had an alternate personality and that it was this jackal-like personality who had pushed him to murder his assistant.

Warren soon designed a costume and some personal weaponry to distance himself as far as he could from his Jackal personality, and began his quest to get revenge on Spider-Man. He pursued his human cloning experiments, successfully producing a perfect Peter Parker clone by altering the genetic structure of a young man named Anthony Serba. Soon enough, however, he realized that his rival for Gwen's affection was also his greatest enemy: Spider-Man. Warren then attempted to recreate Gwen Stacy with her memories up to the time that he had taken her cell samples but the Gwen clone, who was actually a young woman named Joyce Delany whose genetic struture was altered by Warren, revealed that she was in love with Peter Parker and that she had absolutely no romantic feelings for Warren, just like the original Gwen.

However, Warren had programmed the Gwen Clone with posthypnotic commands in order to use her as a psychological weapon against Spider-Man. It initially worked but the Gwen Clone broke free from the Jackal's mind control and confronted her creator. While this was happening, Spider-Man, who had been knocked unconscious by the Jackal, awoke to find himself…facing himself. Only one of the two Spider-Men was real but which one was it? While the two Spider-Men duke it out, a bomb the Jackal had planted nearby suddenly went off, apparently killing both one of the Spider-Men and him. In fact, the Jackal had sent one of his clones to die in his place while he had placed himself into suspended animation in a cloning pod, to later awaken physically improved, assuming the true characteristics of a Jackal. He had formulated this plan to get revenge on the web-slinger, a plan that is now know as the beginning of the infamous "Clone Saga".

It should also be noted that the other Spider-Man had not been killed in the explosion either. He was actually in perfect health and returned a few years later...but that's another story.
