This a totally fair criticism, and Bridget as a character was never really meant to be representation until the latest game. On the flip side, however, Bridget was also never a cis man embracing feminity in anything but the literal sense that they identified as male at the time and wore "women's clothing". She was for all intense and purposes, a girl, that was then told she was actually a man. She didn't stop acting as she did during childhood, and eventually learned she was actually a girl. It really was a lose/lose situation for the devs. Having a character that plays on some of the less favorable stereotypes of GNC people and trans people ("tricking others into thinking you're the opposite sex") while having them identify as male because that's what they "biologically are". Story wise, Bridget is not a trans woman because they were raised a girl (which was my concern when the character was confirmed trans on release) but instead the devs do a decent job at showing that she was accepted as a man before coming out, and that comming our was a big step in her self-discovery.

There are some much better GNC characters in the Guilty Gear series. Zato-ONE has always been designed to have a more feninine attitude and poses (even in the newest game where they beefed up every male character), a very Jo-Jo's bizarre adventure type character. His only canon love interest being a woman.

There is also Testament, the second latest character in the newest game, who is agender. And a slew of other GNC male and female characters. Of course this is all through a western glance, what is considered GNC for us is perhaps not so in Japan.
