Shayuri/Bialaska -
Truthfully, I preferred Shayuri's proposed shapeshifter to Bialaska's, if I had to choose one. I'm not too fond of the 'terminator' take.
I actually didn't see any real problem with Bi's first take on the 'metal suit'... since it wasn't permanent, it's no more of a noticeable hindrance than someone who shoots lightning bolts from his hands. (The problem I had with WD's original 'crystal man' was that it seemed to be a permanent thing). So long as it can be turned on/off, it's hideable and not that much more noticeable.
It also had an easy Drawback - Normal Identity, which I liked.
The ONLY problem I had with your first take on Daisy was the Speed. (Just as a note, unless your character's supposed to be a speedster I'd prefer staying away from multiple ranks of speed.)
