Yeah, it does seem a bit strange. But I've considered the possibility of Master Xehanort allowing Braig to capture him. Either that, or Braig's stronger than he looks.
What gave you that idea? o_o; I'm not sure why they changed it the first time, but the second time Nomura said it was because her top was "too revealing." I don't see why that would only apply to one country.
As Mike said, there's no way of proving Disney had ANYTHING to do with the decision.
In fact, to the best of my knowledge, Nomura was the one who decided it was "too sexy."
The backless version just doesn't make sense-- I think they changed it to that all for fun. The third (most recent) one, I like. The corset-like garment isn't randomly split open. >_>
Oh yeah, and as you are all well aware, Disney IS Kingdom Hearts, just as Square Enix is. Also, Aqua does technically belong to Disney (all KH original characters do), even though they had no part in creating her. And what does this have to do with Kingdom Hearts' story, by the way?
Uh, anyway... Let me repeat my main point for emphasis: Disney most likely didn't tell Square to change the outfit.
