I've had this discussion before with my friend who likes Western comics and he didn't know an answer, so I thought I'd ask here.
I'm more into anime & manga and usually the order of titles like personA x personB, can give you a good idea of what role they play.
What I was wondering was, in Western comics and comic-based films such as the upcoming Batman Versus Superman - does the order ever hint at who will win? For example, maybe the winner always is mentioned first.
I realise this is pretty broad, but I'd be pretty happy with a comparison of the more popular titles and if there's any trend with them.
Also, I don't mind spoilers at all, as it is just a curiosity to me - but you might want to wrap answers for other readers.
