A lot of posts are telling folks that Marc Spector had Disassociative Identity Disorder (DID) before his near-death experience in the Temple of Konshu. This is wrong.
If Marc did have DID, he would have been ineligible for military service. Taking away his former Marine and Merc status is a huge part of his origin.
I never read any of his solo comics. Only read when he appeared in others. I’ll check out the classic ones. Honestly don’t expect Disney to do any characters justice at this point
