If you've ever been to a Hellgate Rollergirls bout, you know that derby is no joke and that girls who skate are complete badasses. With that said, it is no surprise that a 43-year-old roller girl fought off an intruder with a ninjato style sword.

Karen Dolley skates as "Foul Morguean" for the Naptown Roller Girls of Indianapolis and also owns several weapons, including a Japanese sword. When she discovered an intruder in her home, she went for her gun, but got the wrong drawer and wound up with the sword in her hands. Karen used it to threaten the burglar and then punched his lights out until the cops arrived.

Point? Don't mess with roller girls, they will mess you UP!
