one ended up being anyway. In the 2nd one though Superman fought..........the Hulk! It wasn't a long battle but neither really lost. Actually Superman helped the Hulk & caused him to revert to Bruce Banner. In the meantime there were other such joint efforts such as ' Batman vs. the Hulk ' & probably one of the most well known comics featured both the X-Men and the Teen Titans, which by then I believe was presented in more of a graphic novel format but maybe not exactly. In the over-sized ones though there was even a joint effort between Superman & the Fantastic 4. Back in the 90's DC & Marvel joined forces again with a story that I have in graphic novel form somewhere where Superman knocks out the Hulk! Of interest here though is that there ended up being combined versions of the heroes. I believe that Superman was merged with Captain America to form a new hero. Anyway, I read that particular story back in the 90's but not lately so I hate to say whatever came of that team-up. This can be done in the comics but why not have a joint effort on the big screen? I mean, we have Marvel Studios now & WB owns DC so what exactly would have to be done to make it a reality? non_amos wrote: This can be done in the comics but why not have a joint effort on the big screen?
