Black Widow vs. 3

Black Widow

vs.

Catwoman (Selina)
Black Cat
Batgirl (Barbara)

At the same time?

Shes good, but not that good. 1 at a time? Yea she beats them all.

The Black Cat will beat her down, did you see when she went all out aainst the Lizard? You should have made this more interesting, and put in Silver Sable, who I think could take Black Widow as well, in hand to hand combat.
