Warrior
I have this character that I like to build into various scenarios. I built an entire world around her, but she doesn't have her own story yet.
She's confident. She knows her own body and all of the ways it can move, what it can and can't do. She knows her partner and their team. She knows her people, her world, her life, and has the sense of surety that comes from knowing she's walked through hell more than once and come out the other side stronger for it.
She's a warrior. Physically, she and her team almost won a war on their own. Mentally, because she bears the weight of inheriting an entire planet. Spiritually, because she survived war and capture and torture and experimentation and didn't break until she was home safely. Even then, she fought her way back and glued herself back together with just a little help.
She's human. Not literally, because she was born in a different race, in a different world, but in her emotions. She's strong in every way, but gentle and humble. She's not overconfident and arrogant, but simply comfortable in her own abilities. She will eliminate people who threaten the innocent, but then turn around and gently carry small beings to their families. She'll destroy invading armies, then decide to dance or cook or sing like she's never seen blood in her life. She lives the story of the strongest monks sweeping temples.
At the same time, she's wild. Feral, even. She has no mercy for those who threaten innocents. She doesn't blink at carnage. She doesn't hesitate to kill. Her morals are all focused in the same direction: protect.
