[DC] How high above his weight class can Batman punch (and win) if he has no prep time or prior experience fighting his opponent?

If they don’t have blatant superpowers or unreal technology then he can probably beat them. In one storyline Hugo Strange tosses him into a room with three or four people that he genetically experimented on into monsters and all Batman can do is escape because he knows that he can’t take them out single-handedly without prep time. 

At best he could’ve taken out one of the monsters, who were probably similar in power level to Killer Croc or Solomon Grundy, so that’s probably the upper limit he could handle without any prep or experience fighting them.
