That's Karai, leader of the evil Foot Ninja, in the upcoming CGI-animated
Teenage Mutant Ninja Turtles movie. Yeah, they're back:
Slow to return, teen Turtles are back! Carrying on the legacy of the Shredder... please tell me she won't be a dragon lady stereotype, even in animated form. If this was a live action movie, she'd probably be played by Lucy Liu or Kelly Hu.... or Zhang Ziyi, who provides the voice for the character.
