I'm not sure how the color-changing hair came about- I think I just wanted a visual indicator that Something Has Changed and that seemed the easiest and most obvious.
I thought her armor was actually one of the most unusual elements. I guess it's similar in terms of powers? To my eye it doesn't really resemble any of the outfits of the other characters in this jam. The design is inspired by a few sets from Skyrim, and the jewels inspired by the Arc Reactor in Iron Man's armor (yes, really!).
