sorry buddy but you ARE mistaken.. bullseye at no time as ever had any thing to do with healing factors, NOT NOW NOT EVER! in fact, his original brush with adamnatium was retconned, and instead of all his bones his profiles just says his spinal column now. i even have the comic where Bullseye killed Karen Page, and in it when he punched DD in the face, DD thought bubble mentioned that he heard that he had adamantium bones, and from that punch it sure felt like it..... all that was later retconned however,[not the incident just his bones]
so i would reeeaally like to know where you got that idea from about him having a partial healing factor....no seriiously, im really curious😄
