To your knowledg-NOOOOOOOOOOOOOOO ...To my knowledge, they've rarely actually fought outside of hypothetical futures, and I only know of two off the top of my head, and that's Armageddon 1999 and The Dark Knight Returns, and Supes lost in both instances.
NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO ...

So if he has or hasn't is in canon is irrelevant. However, when he has, it is a convincing scenario where I think he could. And that's what was asked, if I think he could or not. Which I do.

And keep the NON CANON in mind, which doesn't even take these comics into count, because they don't have anything to do with the Superman you think to know from the comics.
PS: I'm done with the topic. It doesn't make sense to discuss a topic like that with people who don't know much about comics and as I already stated it long time ago ... it's totally okay, since we're on a fighting game board.
Good night everyone.
