What fight do you want to have happen in a comic, so you can read it.
This includes characters, teams, wars...etc
Or if you want you could add anime vs comics fights as well.
I want to see a fight between DareDevil and Lady Shiva at night. Or maybe a well-written Taskmaster vs Deathstrok.(Hay, a guy can dream).
Or have a cross-over where Hell-boy faces The Lizard, after debating in a very interesting battle thread I participated in.
Alucard(Hellsing) VS Ghost-rider that would be very cool.
