Will the 2014 Godzilla battle Marvel heros?

No to put it simply

No. Never. There is literally below a 0% chance that would ever be a remote possibility.

NO! Why would u ever think they would do that.

No. Why would Marvel want to kill of all their characters?

As I remember hearing from the 1977-1979 comics with this crossover, the groups (not to mention the city) were spared because an ordinary human boy was able to convince Gojira to stop the attack. Not sure how or why this worked though (never read the comics).

It doesn't matter what the story is or was, because you'd never get Marvel Studios to make an agreement with Legendary/Warner Brothers/Toho to make such a dumb idea. Not to mention it would be inconsistent with the tone and feel of the new movie. It'd be like crossing over [i]Agents of SHIELD[/i] with [i]Law & Order[/i]. Wouldn't happen for hundreds of reasons.

A pacific rim and godzilla cross over is possible but not marvel, the amount to pay for the copy right is just too damn much
