Go ahead and ask her then. ^^ BTW instead of double posting, you see that edit button on your post? Use that instead.
...CRAP!!! You made me post the wrong comment in there too. >< *Goes back to fix it*
...There we go.
I think Dante would win because he is the most powerful demon on Earth. And although Kratos is half god, he still can't seem to kill off the big cheese(Zeus)...yet
I can't say much about Sepiroth because I don't know much about him.
But, Kratos can get quite determined, if he were to collect more powers and weapons with assitance from the titans who knows what he could be capable off. But then it goes back to Dante...DMC4 Dante still collects DAs but with no effort, which is why I think he would win. It doesn't even look like he has to try anymore.
