SO, out of the big two, which single character do you truly feel deserves to have an epic, ass kicking story who hasn't really had one yet?
And who would you get to write and draw it?
I would have originally said Wonder Woman, but the New 52 relaunch looks to be the real deal in the epic stakes.
So I'm going to go with Namor as i don't think he's really ever had a solo epic and i think you could do MASSIVE things his setting and history.
And i think i would have to go with Jonathan Hickman, who has a beautiful sense of the epic, nuanced story and Brian Hitch, whose art is likewise :)
