This topic might have been done previous to the forum upgrade but I thought "Eh, why not revisit it again"?
Out of all the Marvel characters that could match the Watchmen in archetype I thought these would do the trick in maybe some sort of pastiche alternate Marvel earth:
Rorschach - Moon Knight
Dr. Manhattan - Molecule Man
Nite Owl - Nighthawk
Silk Spectre - Hellcat
Ozymandias - Baron Helmut Zemo
The Comedian - Crossbones
Diamondback would also work for Silk Spectre but I think Hellcat fits a bit better especially given her ties with Nighthawk in the Defenders and her costume color is closer. Ozymandias was probably the hardest to nail down but I think either Helmut or Magneto (if you want to go the super powered route) are the closest to him. Thought about Punisher for Comedian but Punisher's not necessarily a scum bag so Crossbones works pretty much perfectly.
Anyone have alternate picks for a Watchmen Marvel style?
