I would like to point out Fanatic as a prime example of 'no gratuitous sexualization'. Normally, given any female comic book hero (or, hell, any female in a video game, etc), the more powerful they are, the better the armor they have on, the less they actually wear. This, in contrast to males, where they get mroe and more covered up and bad-ass. Angels, in particular, will always feature a huuuuuge window in their armor for their breasts, and a short skirt to show off other parts. Bleh.
Fanatic, on the other hand, is a bad-ass in every sense of the word. And for once, her armor makes sense- no holes here! Full on protection!
