the prince of persia vs ezio/connor
both are warriors that faced great loss, owned by ubisoft
cloud vs lightning
you know why
spyro vs crash

kat vs ????
this is why I expect to see DLC characters in pairs of twos
I think Seth Killian said himself that DLC would come in pairs, I think it was on a PS Blog post or an article from the past week, I'm completely sure. It certainly allows for fun speculation when it comes to DLC rivals.
