4. Multiple Man
Death of X was a very controversial and criticized big scale event that killed off a large number of mutant deaths. One of the first casualties was Jamie Madrox a.k.a. Multiple Man. Personally, I felt his death was needless and not treated with the respect this long time, fan favorite character deserved. Thus, I feel that Marvel should rectify this and bring him back. The Children of the Atom are making a comeback recently with Resurextion and all of it’s related ongoings. However, they could still use all the help they can get, especially from a character who’s been known to bring some levity to situations.
Unlike other people on this list, there is a way Jamie could come back without an official resurrection. Given his powers of duplication, Marvel could just say that the original survived, but he was hurt badly. Plus, having all those “dups” die took a lot out of him. They could just simply have him recovering in a hospital up the name John Doe.
