Super-Skrull
The Hulk, Namor, Ghost Rider and The Super Skrull brake out into a huge brawl in the heart of New York City, just leaveing devestaion all over the place as the fight ends up righ on the middle of the Brooklyn Bridge, where they are confronted by Superman.
Fight starts on the The Brooklyn Bridge. All four turn on Superman.
Superman destroys them. Clark would just have to make sure he engages them one at a time. Ghost rider's hellfire would be the only thing he could possibly be weak against (magic?), but since they can only hurt evil, poor barton is pretty much useless here. We all know superman can take down hulk. Namor gets flattened even faster. The skrull's force fields are the only thing that will slow him down, but he'll punch is way through and subsequently beat that alien scum into the pavement. (ironic since kal-el is also an alien)
That's why he would engage them one at a time. He's got the speed to simply tackle one of them far away enough where the others couldn't interfere. Superman isn't an idiot, he know's he might lose if he fights them all at once. He could concievably beat them all at once, but he'd have to bring out his planet busting punches...but that isn't in his character to do so.
Hulk and Namor can do some strenght match, and Supes cannot kill GR we saw that his head blown and regenerated back. Super Skrull hmmm...Well donno...But if supes goes ina straight fight he might get smacked. But I donno it's hard to say for me that he looses. But here is a theory for him to get a win...
Using Superspeed fly around the Hulk and burn everything around him fast to make Hulk loose oxygen and revert back (it took GR a couple mins it would surely take less for Supes. And since non of these guys can catch him moving at that speed they wouldn't see him. Then he could BFR GR, and then heat up Namor while superspeed punching him. And I don't know enough about Super Skrull....
It's just a theory to keep my Supes alive but I don't really know how this would turn out.
Super skrull has all the powers of the F4 amplified, along with shapeshifting and hypnosis. He's just a lot more creative in his use of them. Like slicing people in half with the use of his arms and such.
Superman is too fast for this battle. DC characters own Marvel in speed.
It really comes down to how Supes takes them on. Does he try machismo or brains? If he uses his brains, they cannot stop him. If he wants to play hero, he could get his arce handed to him.
