Batman / Batman Joker

How Did Batman Became Joker?

If you’re a fan of the Batman comic book series, you may have heard of the theory that Batman and Joker are actually the same person. While this theory has been debated for years, there have been several instances in which Batman has taken on the persona of Joker in order to either stop him or to infiltrate his inner circle.

But how did Batman become Joker? Let’s explore this fascinating topic.

The Killing Joke

One of the most notable instances in which Batman became Joker was in the graphic novel “The Killing Joke” by Alan Moore. In this story, Joker tries to prove that anyone can be driven insane after having “one bad day.”

To prove his point, he kidnaps Commissioner Gordon and subjects him to a nightmarish experience, hoping to make him go insane. Meanwhile, he also tries to lure Batman into his trap by attacking Barbara Gordon (aka Batgirl) and paralyzing her.

Batman is understandably enraged by what has happened to Barbara and sets out to find Joker. When he finally confronts him, Joker tries to break Batman’s spirit by telling him a joke that is supposed to be funny but ultimately falls flat.

In an unexpected turn of events, Batman actually begins laughing uncontrollably at the joke and eventually collapses into hysterics. It’s at this point that it becomes clear that Batman has finally succumbed to the same madness that has plagued Joker for so long.

Identity Crisis

Another instance in which Batman became Joker was during the “Identity Crisis” storyline in 2004. In this story, it was revealed that several members of the Justice League had tampered with Batman’s memories in order to erase knowledge of their secret identities from his mind. However, when they did so, they accidentally triggered a hidden personality within Bruce Wayne – one that was identical to the crazed clown prince of crime himself.

As Joker, Batman went on a rampage across Gotham City, causing chaos and destruction wherever he went. He even fought against other members of the Justice League, including Superman and Wonder Woman. It wasn’t until they were able to restore his memories that he was able to regain control of himself and return to his true identity.

Batman: White Knight

In the recent comic book series “Batman: White Knight,” Joker actually becomes sane and adopts the persona of Jack Napier (a name given to him in the 1989 Batman film). In this version of events, it’s actually Batman who becomes increasingly unstable and violent as he tries to stop Napier from taking over Gotham City. Eventually, it’s revealed that Napier was actually trying to clean up the city and bring an end to corruption – something that Batman had been blind to all along.


So how did Batman become Joker? It’s clear that there have been several instances in which he has taken on the persona of his arch-nemesis, whether by choice or by accident.

While these stories may not be part of the official canon, they still provide a fascinating glimpse into what could happen if Bruce Wayne ever lost control of himself. Whether you believe that Batman and Joker are truly one and the same or not, there’s no denying that their relationship is one of the most complex and intriguing in all of comic book history.
