There is no doubt that the Joker is one of the most well-known comic book antagonists, yet even after more than eight decades, there remain many mysteries surrounding Batman’s archenemy. This is especially surprising given the character’s many variations. After years of uncertainty, DC Comics appears to have cleared up the mystery surrounding the Joker’s identity.

The identity of Mistah J as Jack Oswald White is made known in Flashpoint #5. Over the course of his illustrious career in both comic books and live-action films, the renowned Batman villain has adopted a number of aliases, with Jack Napier being the most prevalent.
Of fact, the moniker Jack Napier was inspired by Tim Burton‘s 1989 Batman movie; nonetheless, the comics eventually adopted it even though it was originally meant for the Michael Keaton and Jack Nicholson masterpiece. Joker’s new identity as Arthur Fleck and more sad past were choices made by WB for the 2019 film.
It will be fascinating to see whether DC continues to use Jack Oswald White, but I adore the name. The only DC movie currently approved by Warner Bros. Discovery is Joker: Folie à Deux, in which the Clown Prince of Crime will next be seen in live-action.
Barry Keoghan is most likely to be the major antagonist in The Batman 2 in Matt Reeves’ interpretation of the role.
