As someone who used to play roller derby, I can tell you, those girls are tough. That being said, I don't think all but the best skater could hold their own against Batgirl and even the greatest blocker in the world would fly across the rink with even the tiniest bump by She-Hulk.
Of course, I would pay all kinds of money to see a roller derby match between Marvel and DC heroines -though it is hard to imagine any rink could actually withstand the brutality their match ups would inevitably result in.
These adorable derby dames were created by delightful geek artist Kevin Bolk.
