Batman vs. Captain America
There's a little twist to this fight. Both of them have Superman's powers. They have full information to how their powers work. Both get a week of preptime to test their powers. However Captain America gets an extra week since he does not know who Superman is and what he could do with it. etc. Both will use their usual equipment for the battle. (i.e Captain America's shield). Batman cannot use any kryptonite, red light flashbulbs or any of that ridiculous crap. Both are gonna give it their all. The battle takes place in Kansas. No civilians are present anywhere. They can leave the battlefield if they wish.
