how can you even say that superman can win??? thats so wrong! goku would kick his ass. its like saying a little girl could go up vs a tractor. goku could actually blow up planets with not much effort so think about it, if he would could destroy planets and probably galaxys even, how could superman go vs that? all of supermans fights are slow, goku always fights super fast that people cant even see them fighting. how can superman even compare to that?? goku could just shove kryptonite down his throat and that pussy is out. no can mess with gokue ssj3 or even 2
