While looking up the Joker i saw that he had a large number of aliases. Some of them I am familiar with like the Clown Prince of Crime, Harlequin of Hate, Puddin, Mr. J, Jack Napier, and Melvin White. And there are others that I've never heard him been called before like King of Arkham, Public Enemy # 1, The White Duke of Death, Patient 0 and Patient 223, Man of a Thousand False Fronts, Nemesis of the Knight, and Mephistopheles of Mirth. When has he been called these various aliases that i am unfamiliar with in the comics?
