Cassarah

her skin changes color, but the markings/tatoos/scars are still there. she can be any color

The former wife of Caleigh before she was murdered (Cassarah was murdered, not Cal)

She was royalty on her home planet but left to go fight the companies, she was all about trying to find the more peaceful solution but an excellent fighter
At one point cal kidnapped her but couldn't bring herself to turn her in
(hmmm i'm tired but i'll write more at some point, you can pm me if you need to know something)
