I'd say...
DD vs Bats = Bats
Wolves vs Bats = Good match but Bats
Caps vs Bats = BATMAN!
Nightwing vs Bats = another good match Bats
Gambit vs Bats = Probably the second or first toughest out of the fights maybe BATS
Nightcrawler = great match-up, Bats
Blob vs Bats = pleeaaassseee Bats would outlast and find a way to put that big boy down
DD vs Batman = Batman
Wolverine vs Batman = Draw
Cap vs Batman = Draw
Nightwing vs Batman = Batman edges him out
Gambit vs Batman = Batman
Nightcrawler vs Batman = Nightcrawler
Blob vs Batman = Blob
We are talking about fight in one on one right, leatherface and wanderer you made me cry, seeing saying bat would beat Logan and... why, why are you making me sad by one of the most stupid post ever:
Daredevil - Batman lose badly
Wolverine - Logan kills him
Captain America - CA kills him
Nightwing - somewhere equal
Gambit - Gambit kills him
Nightcrawler - Nightcralwer kills him
Blob - Blob eats him
Are these fights just hand to hand? No weapons or powers? If so....
Batman vs Daredevil - Stalemate 50/50
Batman vs Wolverine - Bats 6/10
Batman vs Captain America - Stalemate 50/50
Batman vs Nightwing - Bats 7/10
Batman vs Gambit - Bats 7/10
Batman vs Nightcrawler - Bats 8/10
Batman vs Blob - Blob 8/10 maybe 9/10
Someone thought Bats won all these fights? I'm all for credit when credit's due but... reality check.
I'm assuming those empowered can use those powers if so:
Batman beats Nightwing. He loses or at best draws with the others unless lady luck smiles upon him.
