I'm going to assume that this is a Free-for-All battle.
Brandon Routh would imediatly start trying to get a date with dean cain (who was left out of the lineup, so BR is eliminated for leaving the ring)
George Reeve and the Danny dark Superman would start posing in rediculous stances while trying to look even more rediculous. Then they would arm wrestle and jump and stuff, cuz they cant fly or use heat vision.
We would be left with Tim's superman and Chris Reeves and that would be tough. While tims is a straight up awesome superman, Chris tends to cheat a lot. He may try remove his \s/ and use it as ensnareing devise, or better yet. take off his boot and inflate it to the size of a hot air balloon and trap the other one inside.
If all else fails, he'll just keep flying aournd the world going back in time untill he gets what he wants.
