Atlee aka Terra from DC Comics. This is her look as depicted in Power Girl and her Solo series.

Triggers: atlee, black hair, short hair, purple eyes, leotard, thighhighs, cleavage, fingerless gloves

I'd recommend a strength of 0.7-0.9. For whatever reason the hands are really wonky with this LoRA, which is probably due to the source material. Lower strength seems to help fix that.
