Cougar

Mosi Queen is the adopted daughter of Black Canary and Green Arrow. They took her in after the murder of her abusive parents, but they didn't expect her to come with powers. She is a Skinwalker. She turns into a Cougar as self defense, but can also jump fifteen feet in the air, has an excellent sense of smell and hearing, and can heal herself and others. She is good friends with Robin, Wally, Roy, and Artimis, but one little bird is hoping to be more than just friends. Will she return the feelings? Read to find out.
At beginning of first season.
