Belline

Her name is Belline, she's a female Mutezik with a baaaaad reputation,  ranging from "blunt and rude!" to "danger to everyone who goes near  her!" and she doesn't even deny any of that. She really is rude,  and can be very aggressive, attacking others and getting into fights  when they're too uppity for her taste. She swears like a sailor, fights  like a feral beast, but carries herself like a queen and demands the  respect of others. Funnily enough, in ancient times, she probably would  have been, since she is a strong fighter, charismatic despite her  rudeness and radiates a certain air of authority when she really wants  to. But now, nobody pays her respect just for that and she usually lives  as a lone wolf when she's not crashing parties.

However, below  her rough exterior, her heart is warm and big. She never completely  ceases to be rude, but if someone sticks around for long enough, they'll  eventually notice that many of the blunt comments she makes carry  positive or even loving messages or lead up to such, and with her lack  of care for politeness comes an honesty that is hard to find in such a  pure manner. She's also fiercely loyal once she considers someone worthy  of her affection, and recklessly puts her life on the the line when  those of others are at stake. Especially weak and vulnerable Muteziks  also sometimes get to experience a more motherly side of her - no, she  won't stop giving them ridiculous nicknames, but she'll help them get  back on their feet and protect them for as long as they need it.

She  also picks up orphaned cubs if she finds them and raises them like her  own children, which leads to her nickname "Mama Belline" from those who  actually come to like her.

On a more mundane note, she's 30cm tall, weighs about 12kg and never tells her age.
