Marv is beyond human, He survived tons of bullets and kept going, He got hit by a car twice at full speed and it didnt phase him, And it took two tries of the electric chair to execute him...Miho is bullseye level assasin, She never misses and is very proficiant with swords... Keven is slightly below batman level martial arts and hes completly insane and hartigan with his hand cannon is tough as... I dont see Batman doing anything in sin city besides dying a long and painfull death.
