Who would win in a fight?
Avengers + Godzilla = a movie that wasn't long enough
Thor, Iron Man, or the Hulk could take Godzilla alone.
You have Godzilla, we have a Hulk.
I'd be rooting for Godzilla
Thor could just throw his hammer through Godzilla, Iron Man could blast him to death, and The Hulk would have a pretty cool fight.
