showed them! Now I can keep an eye on everyone. They'll never slip past me again". History in the comics Lock-Up's first comic appearance was in Robin (vol. 2) #24 (January 1996) in which he captured Charaxes. He subsequently appeared in Detective Comics #694 (February 96) in which he captured the minor villain Allergent. In both of these stories, he only made a brief appearance at the end, removing the villain before Batman and Robin could return to the scene. His first full appearance was in Detective Comics #697-699 (June–August 1996), which began with him capturing Two-Face and taking him to his private prison alongside Charaxes, Allergent, and several gangsters. He is stopped by the police while targeting a criminal-turned-state's evidence and is revealed to be Lyle Bolton, previously discharged from the police academy for being too gung-ho, and dismissed from several security jobs (unlike the animated version, he had not worked at Arkham). Lock-Up escapes, and captures minor street criminal Alvin Draper (actually Tim Drake's undercover identity). When Nightwing finds his hideout, Lock-Up decides to drown all his prisoners in an underwater death-trap. Batman intervenes and defeats Lock-Up, saving the villains, Nightwing, and Robin. Lock-Up later appeared during the No Man's Land storyline, having taken control of Blackgate Penitentiary in the aftermath of the earthquake. He had enlisted KGBeast and the Trigger Twins to act as wardens for his prison, and rules with an iron fist; Batman only tolerates his presence because he requires Lock-Up to keep captured criminals in check to prevent Gotham being overrun, although Lock-Up is under strict orders to treat the prisoners well. Towards the end of the storyline, Batman enlists Dick Grayson's help in overthrowing Lock-Up so Blackgate could be used for the lawful side once again. Lock-Up makes a very brief appearance in Villains United: Infinite Crisis Special where it seems the Society made use of Lock-Up's prison expertise to break metas and humans out of prisons all over the world, leading to the Battle of Metropolis in the final issue of Infinite Crisis. More recently, Lock-Up has been affiliated with Ventriloquist II, alongside other Gotham criminals Killer Moth and Firefly. During this association, Lock-Up was badly wounded by Metropolis outfits Intergang and the 100. Recovering, Lock-Up was sent to a prison world alongside other criminals in the Salvation Run limited series. Lunkhead Lunkhead is an enemy of Batman who became an inmate
