I can´t believe that are people wanting to change such a key element of her. I thinking you´re missing the point, Darkstalkers was the fighting game of monsters from capcom, classical monsters, are all there, draw in a Mangá style, with comic element in it. That´s it, she is not batman´s catwoman.
I think the problem is because Morrigan is so famous today and she is maybe the only character that have proportions more or less close to the real, people start to expect this from all others, this are all cartoons, you can´t redraw Bugs Bunny or Tom and Jerry to look more real, that doesn´t make sense.
