As comic book readers we like to speculate what would happen if one character were in another comic universe. We've seen crossovers between Marvel and DC Comics but there hasn't been one in years. Even with the New 52, we've had the same heroes fight the same villains for decades. What if that could change?
In the 80s, it turns out Marvel almost started licensing several DC characters. Jim Shooter posted last year about how they were approached by DC since Marvel was doing a better job licensing their characters.
This is where you get to share your thoughts below. Would the heroes in the Marvel Universe put up with his antics. How would the scenarios play out? Could Joker fight Spider-Man, the X-Men or the Avengers? Let us know what you think.
