Batman Twisted Comics

The Arkham City comic book tie-in series is set six months before the events of Batman: Arkham City: A riot orchestrated by the villainous Joker had occurred at the asylum, which served as a mental institute for the criminally insane housing Batman's worst enemies. The Dark Knight was able to bring it under control, but not before Arkham was left in ruins following a final showdown with his nemesis, who had injected himself and numerous other test subjects with Titan, a Venom super-steroid derivative which had the ability to turn men into maddened monsters. A mutated, beastly, Joker attempted to destroy Batman during the chaos, but after his eventual defeat was left sickly and weakened.
