Who is Hyena (Day)?

Origin Summer was the first child born to Bert and Helen Day. Bert was deeply disappointed not to have a son, and so to earn his love, Summer spent her youth trying to excel in academia and athletics. In many ways she felt pushed into being the son her dad never had, especially after the Day's second child, Doreen, was born. Over the years, Summer tried but never measured up to the expectations of her police officer father. The final blow came when she failed as a police cadet and he never said a word. Her frustration turning to hatred, Summer left home and joined the peace corps. While in Africa, Summer found a native wounded by an arrow. As she began to treat the wound, he turned on her and bit her face.
