Toughened by a childhood in the Chicago ghetto, Perp is a "rookie" in the H.A.R.D. Corps. When the Deathmate alters reality, Perp becomes the greatest leader in the history of the H.A.R.D. C.A.T.S team. Sadly, he is also the most tragic martyr, having lost his life in battle at the hands of the Harbinger, Big Boy. Months later, his teammate Maniac, finally avenges Perp's death.
