and resented Firestorm for interfering in their vendettas. The unique feature of the Hyenas was that they turned into werehyena forms whenever they were under great emotional stress, not only when there was a full moon. This meant that they could attack foes in broad daylight and that they would revert into their human forms when their emotional tension was relieved. The first Hyena, Summer Day, joined the Peace Corps as a result of relational issues with her father and was turned into a werehyena as a result of an accident in Africa. Taking the name the Hyena, Summer returned to America and began attacking both criminals and police officers. A result of her condition is a steadily progressing madness. The second Hyena, Doctor Jivan Shi, was a psychiatrist whom Summer Day had fallen in love with while he was attempting to treat her werehyena condition. One night, as Summer and Jivan were embracing, Summer transformed into the Hyena and infected Jivan with the werehyena curse. Professor Stein noted that being the Hyena seemed to have warped Jivan Shi's mind. According to The Fury of Firestorm #10–13, the madness suffered by the werehyenas is one's bestial side taking over, coupled with an exaggeration of negative emotions. In Infinite Crisis, Deadshot killed one of the Hyenas after a prison breakout and the other appeared as a member of the Injustice League in One Year Later before being shot and killed by Parademons that were attacking the villains' camp. A pack of at least five new werehyenas, presumably suffering from the same curse as Summer and Jivan, were seen in San Francisco some time after the death of their remaining predecessor. They were promptly defeated and permanently returned to human form thanks to Zatanna, the Vixen and the Black Canary. In 2011, The New 52 rebooted the DC universe. The Hyenas are reintroduced as mercenaries who received special drugs that gave them super-strength and super-velocity, with the side effect of a constant laugh. During the Forever Evil storyline as part of The New 52, the Summer Day version of the Hyena appears as a member of the Secret Society of Super Villains. The Crime Syndicate sent the Hyena with Black Bison, Multiplex, Plastique and Typhoon to finish Gorilla Grodd's job. The villains were defeated by the Rogues, since one of the targets was the hospital that was treating Captain Cold's sister. References
