Whaaat? What's wrong with other SF female characters?
I just don't like any of them except Chun Li, the rot set in for me as early as Cammy, the second female character ever in the series - to this date one of the most ridiculous female character designs in any fighting game, though, granted a good cosplayer Cammy is an amazing sight to behold.
Yeah it's a sexy design, but nothing more than that in a fighting game context IMO, the rest have all been much the same, either hyper sexualized or looking like they couldn't punch their way out of a wet paper bag, though I did think Mika was at least an original looking design.
In fairness there's been plenty of terrible male SF character designs too, T Hawk, Gill, etc.
EDIT: I have to admit I'd forgotten about a few of the roster and in hindsight I do also think Ibuki and Makoto are great female character designs in SF, but because both, like Chun Li, are primarily dressed in a functional martial art style, and not trying to be deliberately cute or sexy, it just adds so much more integrity to their characters.
Too many fighting games have vapid, 'sexy' and totally unrealistic female characters, I just prefer more grounded and legitimate characters in fighting games in general.
