" The Laughing Bat " is a standout episode from Season 2 (Episode 4) of the 2004 animated series The Batman, originally airing on June 4, 2005. It is highly regarded for its dark, "personality swap" concept where the Joker attempts to take over Batman's role, while Batman is slowly driven insane by the Joker’s toxin. Plot Summary
The Joker as "Batman": Tired of being defeated, the Joker decides to "be the Bat" instead. He dons a makeshift Batman costume and begins a reign of terror by brutally "policing" petty offenses—gassing citizens for jaywalking, littering, or having too many items in a grocery express lane.
The Transformation: Seeking an arch-rival, Joker injects the real Batman with a slow-acting, lethal strain of Joker Venom. The toxin causes Bruce to suffer uncontrollable laughing fits and makes him act increasingly like the Joker.
The Race for a Cure: Batman has only one hour to find a sample of the venom to create an antidote before the toxin kills him.
The Climax: The conflict culminates at the Gotham Museum of Art, where The Penguin is attempting a heist. A chaotic three-way battle ensues between the Joker (as Batman), the Penguin, and the toxin-infected Batman. Key Highlights & Trivia
Batman’s Joke: In a rare moment, Batman defeats the Joker not just physically, but by telling a joke ("A man walked into a bar... and said 'Ow'") that makes the Joker laugh so hard he lets his guard down.
Comic Book Influence: Many fans note that this episode serves as a thematic precursor to the modern comic book villain The Batman Who Laughs, an alternate-universe Bruce Wayne who is permanently corrupted by Joker toxin.
Personality Swap: The episode is praised for the voice acting of Rino Romano (Batman) and Kevin Michael Richardson (Joker), as they effectively trade personas, with Joker becoming more somber and Batman becoming uncharacteristically manic.
Superman Nod: The episode includes a Clark Kent-style reference where Joker, dressed as an office worker, sees his "Jokerwave" go off and says, "This looks like a job for... The Batman!". "The Batman" The Laughing Bat (TV Episode 2005) - IMDb Before the terrifying " Batman Who Laughs "

When fans discuss the greatest interpretations of Batman, the usual heavyweights come to mind: Kevin Conroy’s stoic gravitas in Batman: The Animated Series, Christian Bale’s gritty realism in The Dark Knight, or even Adam West’s campy charm. However, one of the most overlooked and genuinely terrifying reimaginings of the Dark Knight’s mythos comes from a single episode of The Batman (2004). That episode is "Strange Minds," and it gave birth to a nightmare dubbed by fans as "The Batman 2004 Laughing Bat."
This iteration is not a hero. It is a monster. It is what happens when the Joker wins without throwing a single punch.
During the golden age of internet horror stories, a user on the Creepypasta Wiki wrote a fake "lost episode" entry for The Batman titled "Laughing Bat." The story claimed that the episode aired exactly once at 3:00 AM in 2006. In the fake plot, Batman kills the Joker, but the Joker’s spirit infects the Bat-computer. Every screen in the Batcave shows a smiling bat. Bruce Wayne goes insane and starts laughing while putting on the cowl.
The story included a "screenshot" (actually a fan-edited image of the bat-logo with teeth). The myth stuck. To this day, many fans searching for "the batman 2004 laughing bat" are looking for this lost episode. It does not exist.
There isn't a well-known Batman film or related media from 2004 specifically focusing on or prominently featuring a "laughing bat."
