Gotham City
Mayor Armand Krol first appeared in Detective Comics #647 (August 1992). Like Hamilton Hill, he did not like Commissioner Gordon. Krol also did not like Batman until the "Knightfall" series, during which Batman saved his life. Krol died of the "Clench" virus released by Ra's al Ghul in the "Legacy" story arc (Detective Comics #699, July 1996).
