naw, he hasn't faced/seen anyone as powerful sup....the only person he knew about that was just as powerful, sup killed....and with the shyt he saw happen in metropolis, the only thing he was focused on was superman, he had tunnel vision....
as for what he's seen, for the most part the people he's probably faced were reg people with good toys, but no super powers....his rogue doesn't have super beings in it...
Fair enough. Guess I'm going off of Man of Steel. I thought the world got the you are not alone message especially a people possibly in the same state since they were separated by a bay. I can ride with the tunnel vision and I ain't nitpicking but with Bruce's paranoia and two years of that legendary prep time, would have been cool if he wasn't completely in the dark on meta humans. Nevertheless it is what it is.
True his rogue gallery doesn't have super beings per se, but the Croc exist in his world, as well as katana. They were in the same prison so he gotta know they exit or at least have heard of magic and mutants. they aren't exactly typical mobsters and criminal masterminds. Dunno if he has experienced Ras or the likes.
