Fan CastingBatman: Day Of The Jackanapes

One snowy winter night in Gotham, a portal opened in the sky above the theme park from the "Killing Joke", and through it fell a clown. Turns out that this clown is the Jokester, a heroic version of The Joker from Earth 3, a twisted alternate universe where the villains are good and the heroes are bad. He wound up coming into our dimension during a battle with Owlman & The Crime Syndicate, and he was pushed through a portal that led to our dimension. Now without a way back to his home, Jokester decides to make the best of a bad situation; IE fight crime in this world until he finds a way back home. Unfortunately, he wound up being mistaken for the Joker, leading to him being hunted by Batman, the Bat-family, & the GCPD. Meanwhile, word of this new Joker reaches the real Joker while he's in Arkham Asylum. Angered that someone is besmirching his reputation, Joker breaks out of Arkham in order to kill this "cheap phony". The tension keeps building and building until it reaches a crescendo of madness that ends in a battle between Batman, the Bat-family, the Joker, the Jokester, & the GCPD at the Amusement Mile boardwalk theme park.
