Bizarro Joker Settled a Major Fan Debate

DC Answered Whether Joke Is Truly “Insane”

One of the biggestfan debates regarding Jokeris whether or not he’s actually ‘insane.’ While several stories have seemingly confirmed this, showing the Joker has a different personality when his mental state is stabilized by an outside force, many others have suggested the opposite, suggesting that Joker is totally in control of his actions, and is simply a purely evil person. The iconicArkham Asylum: A Serious House on Serious Earth(from Grant Morrison and Dave McKean) went further,suggesting that Joker has a form of"super sanity,“seeing the world and his decisionsmoreclearly than anyone else on Earth.

However,“the most sane man on the face of the Earth"settles that Jokerisactually mentally ill.

The new"most sane man on the face of the Earth"is just the latest expression of an idea many creators have explored, but it’s also unique in how absolute the transformation is, how definitively the story is set in DC’s mainstream canon, and how explicitly it addresses the nature of Joker’s madness.
