Trivia

 * This is the fifth version of "The Joker" in media to be given an actual name and backstory, following Jack Napier in the 1989 Batman movie, Martha Wayne in Flashpoint, and Jerome and Jeremiah Valeska in the television show Gotham.
 * His backstory as a failed stand up comedian is similar to one of his possible backstories depicted in the acclaimed comic book The Killing Joke.
 * His appearance appears to be a mix of Cesar Romero's Joker from the campy 1960s series Batman, as well as Heath Ledger's Joker from the 2008 film The Dark Knight.
