I had a conversation like this with my brothers, and some pretty interesting opinions were thrown around. I want to see what other people think as well.
To EmperorPalpatine: yes, basically, but with more than just star wars.
To theregulator: I hadn't thought about it that much, but it would have to be some place that would not give anyone any specific advantages over the other combatants. I mean, we can't have superman go toe to toe with, say, the hulk in a room filled with kryptonite. that would be unfair. So just assume that they are in a place where no one is at a location based disadvantage.
The only thing that can hurt Superman is kryptonite. If nobody has any of that, I'd say him. But there are so many heroes and villains out there, it could go in anyone's favor because of all the possibilities.
Hey firetail_madness, that guy who runs away wouldn't get far enough away before Darth Bane would be able to produce a brain-death field with a radius of around 700 miles.
Also, I think Hirudegarn from DBZ would win. His powers include: -breathing fire -super speed -super strength -the ability to absorb life force through his tail -flight -phasing through attacks by becoming a gas -the ability to exist in two different halves in the unlikely event that he gets cut in half -and, oh yeah, the fact that he is about 3 kilometers tall
Hirudegan was destroyed by SS3 Goku... That isn't even Goku's SS4 form. You might even go so far as to say Goku is the Japanese version of superman. I never read the story... but I do remember there being an instance where Superman dies... "The Death of Superman"
Did he die w/ or w/o the influence of kryptonite?...or was it a different colored sun? I know some kind of plot twist brought him back... but he still died.
The DBZ crew have been known to destroy planet sized astral bodies somewhat easily... not to say that the super monsters like galactus couldn't compensate in some shape form or fashion.
