Fair enough... in that case ill mention the 2 characters i have in mind here now and go from there...
The first one i thought of was a rabbit girl, human aside from some minor things like bunny ears and a tail. With a personality somewhere between shy a skiddish, but affectionate once she starts to trust you. I imagine her coming from a futuristic, yet slightly dystopian world, where laws are more of a fantasy then anything... so she preferres to avoid others when possible.
The second is something along the lines of a street thug brawler mixed with a fantasy style tribe leader. Personality wise she believes the weak should obey the strong, that said if she knows she is the weaker of the two she would submit happily... that said her world was on the primitive end... barely able to make stone tools...
