I really thought this concept would get a much bigger response. To fill the void I'll mention 2 so can pick the one you like best. First one I thought of is Faith the vampire slayer; she has limited super strength, agile and is Boston style sassy. She was a villain for a couple of seasons so she fits the bill. Plus she never fought a character with a big chest so that'll be a treat.
2nd is a little weird, but I was thinking of an Uncle Sam type character but for Germany. In Dc Comics Uncle Sam is the spirit of America and has various powers but actively fights against the country's flaws. So the German version(for now we'll call her Auntie Gertie), is considered a villain but doesn't want to be one anymore. Like Germany she's really trying to shed the Nazi image, but in her case she may be overcompensating. She tries to befriend the nearest minority in the room, if she's fighting a Jewish woman Auntie Gertie can't hit her so she has to to smother them out. For her looks imagine Anna Semenovich but dressed as a nazi, but she used a sharpie to turn the swastika's into windmills.
Just throwing it out there; maybe she can summon large mugs beer from out of nowhere?
