Dinosaur Island was a hidden and unknown island in which many prehistoric creatures, primarily dinosaurs, survived, free of both extinction, evolution and faced no possibilites of overpopulation. The island's location was relatively unknown, with few military personell, the Teen Titans and the agents of [[Batman Incorporated] having had ever been there. Batman Incorporated took full advantage of the island's unique state and built an underground supermax prison there for arms dealers. Many of these prisoners were lured there by the leader of Batman Incorporated and the unofficial warden of the prison: Batwing.
