Danielle Moonstar in her classic New Mutants costume.
I tried a bunch of outfits to varying success, but they're there if you want to try them.
New Mutants: danimoonstarclassic, native american, black hair, long hair, twin braids, brown eyes, bodysuit, blue belt, gloves
For this, if you use blue belt, be sure to put x logo in the negative. Otherwise you can use red belt and it will do the classic red belt that every character wore rather than Dani's unique blue one.
Black Bikini: danimoonstarclassic, native american, black hair, hair bun, brown eyes, black bikini, o-ring bikini, strapless
Roma Bikini: danimoonstarclassic, native american, black hair, twin braids, brown eyes, bikini, bikini armor,
