I never created Batman TAS.
Lock-Up wasn't worried about the barren streets he wandered. People always committed crimes. Robbers. Killers. Just the ones perfect for Lock-Up to lock up. Perhaps imprison for life. If he had his way.
Chains remained around Lock-Up's wrists and arms. Chains used for capturing criminals. Any villain unfortunate enough to cross Lock-Up's path. Anyone causing mischief. Let a hero try to stop Lock-Up. He was prepared for anyone.
Lock-Up thought he heard footsteps in one alley. A smile formed behind his dark mask slowly. His eyes widened as soon as a stray dog appeared and ran out of the alley.
THE END
