Probably there's not many besides Bayonetta and Lady Death that would drawn in a big auddience. Buffy is own by 20th Century Studios/Disney and Joss Whedon is under hot water right now. There's also Rayne, but her series is pretty niche though.
Thats a good point! its Always dudes!
its defo time for a female guest character!
Not typically a fan of guns in MK but Classic Lara Croft would be pretty Sick
also Aphrodite IX has a great design,
maybe Tank Girl could be like a cheeky female Johnny Cage.
Harley Quin would be an obvious choice too.
