Kinda funny how Vivian TTYD being a trans woman hinges on whether Beldam is a transphobe or not in the remake/remaster
Congratulations! Transphobia is canon!
To explain, in the Japanese localisation, the group is called the Shadow Sisters, while in the English version of the original game, they're called The Shadow Sirens. In the Japanese localisation, Vivian is misgendered and bullied because Beldam sees her as a "man", and doesn't consider her to be a part of the sisterhood.
The remake decides to follow the Japanese localisation a bit closer. Beldam is withholding calling the group "Shadow Sisters" because she doesn't consider Vivian to be one. Vivian being a trans woman is only ever confirmed because of Beldam's transphobia.
No yeah, this is good. Confirmed trans through tramsphobia is still representation, and you get to hit the transphobe with hammers and light her on fire and stomp on her head.
Like, I think characters should be allowed to be X-ist or Y-phobic as long as they're meant to be viewed as villains, or at least as long as those traits are meant to be viewed as negative parts of them.
