Mister Cipher was a masked gang lord who worked in Gotham City and provided the service of plastic surgery to the criminal element of Gotham, allowing the thugs to adopt different identities and avoid capture. Commisioner Gordon sent a large group of undercover agents to infiltrate Cipher's gang in order to learn their activities. When the infiltrated agents were discovered, Batman and Robin located Cipher's secret base of operations and took the whole gang down. When the police arrived at the scene, Cipher tried to use his gun against the officers, but he was shot before he could fire his weapon and died instantly. Batman and Gordon later realized that Cipher had modified his face many times and he couldn't be recognized.
