Coraline

Born common from two alphas she had Big Feelings about that
Her parents are very nice she's just stubborn as fuck
she wants to be big and strong and scary but she isn't really big, not even for a female
her brother is basically as tall as she is and she's not happy about that
Definitely will argue with you and refuse help even if she needs some maybe
She's a spitfire, always ready to talk back and seemingly doesn't fear death at all. She's pretty emotional, but the biggest emotion she has is anger so that's probably the easiest to see. She's gonna be part of a nomad tribe that goes around and fights others for resources for a large part of her childhood and possibly for a while after her rite.
