TYGER Security, inspired and named after William Blake's famous poem, 'The Tyger', was a rogue private military firm contracted by Quincy Sharp to police Arkham City. It was awarded a bid to restore order to Gotham in the wake of the T&T terror attacks, and subsequently to supervise Sharp's Arkham City project. TYGER personnel answered only to Hugo Strange and shared a universal hostility towards Batman, the product of intense programming. They were instrumental in carrying out Protocol 10.
