Since Mona Lisa appeared in the 1987 TMNT series [along with other characters-like Leatherhead], why didn't she come out in the 2003 TMNT series? From her first appearence in the show, I actually liked her and wanted to see more of her, but that was the end of it. I think she would have been great in the 2003 series (alot cooler)-afterall, Leatherhead appeared there and so did the Krang. Of coarse, maybe her story might change a little-possibly something interesting and maybe a connexion that leads her to the turtles, but anyway I would loved to have seen her in that show. I especially think she should come out in the new 2012 TMNT series!
