Jack would have made an ideal Wolverine if he was only 25 years younger. He had the side burns, and he had the ideal temperament to be Logan. When Jack goes into his berserker rages, I see Logan. All he needed was the claws and Jack was Wolverine, ready made. He had the lure of the ladies man, much like Spider Woman Jessica Drew had Pherimones to make men obey her, I think Logan had the same thing to make women obey him.
