Revy of Black Lagoon vs. Batman. The fight takes place in the Ring of Trials. Batman is limited to the use of Bat'o'rangs only and Revy has her twin Beretta 92s and a grenade launcher with two rounds.

Batman easy 10/10

I don't know, I mean, Reby is pretty nuts. She wipes out entire platoons of mercs and soldiers on her lonesome with out any effort and she hand to hand'ed Roberta to a double ko. Roberta was chasing down cars and was sandwiched in between a car and a steal shipping bin after the car slammed into it full tilt (her body left an impression on the side of the bin) with out being and worse for wear... but Revy beat her to a pulp.

Revy is like Spike Spiegle on crystal meth, I'd give her decent odds against Bats in this senerio.

Revy is one of the weakest street levelers in all of anime fiction, batman spanks her and tells her to go get a life.

Revy is a good gunslinger, I would say she fare the same level as Deadshot.

4/10 against Batman is being nice.
