Shahari is the adopted daughter of M'Baku, King of Wakanda. She was adopted by M'Baku when she was three, her biological parents were killed in a war between the Hyena tribe and the Panther tribe, but she doesn't know. On her 18th birthday, she gets to start living in the outside world, in Toronto, you come across her on the street a couple of days ago and became friends. (This is just made-up shit, not actually part of the real Black Panther story-line)
