supermanvs kryptoniteman

I think the kryptonite man would win because he could change superman's costume to green kryptonite and he would be too weak to take it off . And every day he would get weaker and weaker. Instead of that blue and red costume it would be glowing green,haha

uhm can he do that?

Yes what ever he touches turns to kryptonite, he has the midas touch
