Gender locked race?

[Shippuu]

Suzaku has a wifu form, Tomamo No Gozen has a wifu form, and Ultima the High Seraph also has a wifu form - check ff12.
Dragons don't count they're fully 'beast like'...unless you're into that thing.

Arbitrary. It doesn't matter if they have waifu forms, they still have forms we fight them in where they're full on bestial. SE still had to develop the assets for them in their monstrous forms when they could have just gone straight to the waifu forms. And the dragons are still female enemies that look like beasts. They don't get to not count because then in order to make something visually look female it has to have feminine traits, of which you would just call it waifu pandering again.

And bringing in examples of waifu forms from other games? Really? Like, the entire prospect of people using Sophia, Garuda, Shiva, etc. as examples of some design bent when they're all throwback enemies from a history of Final Fantasy games and so their design is less intended to be attractive for attractive sake, and more to call back to the long history of how these enemies have looked in Final Fantasy games. There's little point in including these enemies that have that history if you're going to completely change their design to the point they aren't recognizable.

I mean, we were talking about primals (at least I was) since primals are going to be the most commonly seen enemies for most and very iconic, but go off.

Suzaku is a human for 85% of her fight. She's definitely the least feminine out of all of the female primals, but she's still beautiful.
Ultima's top half is a beautiful waifu. Not that I have a problem with this design, it fits her.
Tamamo no Gozen walks around as a beautiful Au Ra before transforming in her fate.

Tioman and Twintania are cool bosses. No problems here.

Ah ah ah, no arbitrary restrictions here. There was nothing in the context of what I quoted from implying this was restricted only to primals. And dungeon bosses would be the most commonly seen enemies considering the majority of the playerbase does not do Extreme trials, meaning they would see those primals once during the story and that's likely it.

Suzaku is still an example of a beastly looking female enemy.
Ultima: So as long as half the body is vaguely waifu it doesn't matter that the entire lower half is a godless abomination. Interesting standards.
Tamamo is another auspice, so her Au Ra form isn't her real form, her true form is the giant wolf monster.
