funny how they skipped the death of robin...i read the comic back in the day....that would be a kool story..
also i've read about batman vs superman...in the comic i think superman had an heart attack or sumthin while they where scrappin..also the comic spiderman vs wolverine was classic...that would be a good flix...
they havent skipped robin (although i doubt they will include him in these new sets). the new set of batmans started before bruce wayne was batman.
i think batmna v superman or spiderman v wolverine is stupid. first, it lacks any creativity to just take two already established characters and pit them against each other. second, why would two 'hero's' fight each other. thats my take anyway.
If you read "The Dark Knight Returns" (what Thumper is referring to), you'll see an excellent buildup to a final Superman/Batman showdown. Without spoiling too much, suffice to say Superman is firmly on the side of the American government, who frown upon an out-of-retirement Batman's return to vigilantism. So both are still heroes, but have aligned themselves with different stances about the appropriate use of their powers.
Dark Knight Returns was one of the first major works by Frank Miller (who also wrote the original Sin City and The 300 graphic novels), and is BADASS. What seems less plausible is the very human Batman standing a chance against the nearly invincible alien Superman, but the books make a good fight out of it anyway.
