Death Battle Fanon Wiki

All it takes is one bad day to reduce the sanest man alive to lunacy. That's how far the world is from where I am. Just one bad day. You had a bad day once. Am I right? I know I am. I can tell. You had a bad day and everything changed. Why else would you dress up like a flying rat? You had a bad day, and it drove you as crazy as everybody else... Only you won't admit it!
~ The Joker

Introduce a little anarchy. Upset the established order, and everything becomes chaos. I'm an agent of chaos...
~ The Joker

A lion doesn't pass judgement on a gazelle. Cancer doesn't pass judgement on a brain. I've been saying this all along. Evil doesn't exist. There are only actions. We got to the same place: the top of the food chain. Just on different paths. Mine was more fun.
~ The Joker

Comedy is subjective, Murray, isn't that what they say? All of you, the system that knows so much: you decide what's right or wrong the same way you decide what's funny or not.
~ The Joker to Murray Franklin

The Joker is one of the main antagonists from DC Comics and the arch-enemy of Batman. He previously fought Sweet Tooth in the 62nd episode of DEATH BATTLE!, Joker VS Sweet Tooth.

With Harley Quinn[]


Little is known of the Joker before he came to Gotham. In fact, there is no way to identify who he is by fingerprint, dental record, or DNA matching. Though a psychopath, Joker prefers calling himself "ahead of the curve". Regardless of his identity, former mobster wearing a red hood or twin brother to serial killer Jerome Valeska, the Joker is considered one of the most dangerous criminals in Gotham due to zero empathy and sick sense of humor via mass murder.

Death Battle Info (Fanon)[]

Joker uses a wide variety of instruments to exact his homicides, a genius at criminal activities and being a step ahead of the law with acting skills and a sufficient expertise in chemistry to be make deadly weapons based on party-gag items. He is also shown to be a skilled, fearless, and unpredictable fighter who is a strong hand-to-hand combatant. This is due to his utter lack of self-preservation, showing a casual indifference to pain and extremely fearless as he laughs in instances where his own death was seemingly inevitable. He also has a habit of being an unbelievable escapist and has stronger endurance than a normal human being. It was once even presumed he was an immortal being known as "the Pale Man".

    • The poison acts like Nitrous-Oxide: forcing the victim to laugh uncontrollably. The muscles on the victim's mouth are contorted to resemble a massive grin. The poison paralyses the victim's breathing or disrupts the brain; making them suffocate or fall comatose after suffering a painful spasm or seizure.

Emperor Joker[]

I actually Grasp the concept that if you obliterate reality, then there's nobody left to play with. The Joker, However, does not care! He's a HOMICIDAL MANIAC!
~ Mxyzptlk
Emperor Joker

Emperor Joker is the Joker with the stolen powers of Mister Mxyzptlk (or Bat-Mite in Batman: The Brave and the Bold).

Fanon Wiki Ideas So Far[]

Possible Opponents[]

Death Battle Info[]

A form achieved by the Joker after absorbing the powers of the 5-Dimensional Imp, Mxyzptlk. He managed to recreate the world in his own, cruel image using said powers.


  • Murdered Batman endlessly. [16]
    • Batman was almost permanently traumatized if it wasn't for Superman absorbing his memories. [17]
    • Also killed the Batman Family.
  • Turned Harley Quinn into a constellation
  • Shaped the entire Justic League into his own version
  • Remakes the universe with extreme casualty
  • Turned other villains into clowns; Two-Face into a drawf and Lex into a jester.
  • Turned Aquaman into a fish that cannot survive in water, Flash into an obese fast-foods addict, Wonder Woman into a frail house-maid, Martian Manhunter into a parody of Marvin the Martian, and Green Lantern into 'Yellow Paper Lantern'. He also made Plastic Man into a criminal who mimics the plastics in creditcards to steal from ATMs.
  • Mind controlled a Guardian of the Universe, the Wizard Shazam, Zeus, High Father, and Darkseid. [18]
  • A similar transformation dominated Hulk and Batman


  • Mxyzpltk points out that Emperor Joker does not have the same experience of these powers as he does, and so has yet to perfect them. But he also pointed out that it wouldn't be long until Joker achieved such experience.
    • Because of this inexperience, Joker's actions can be reversed if he loses his powers or is defeated. However if Joker did master his powers, then the damage he caused would have been irreversible.
  • Mxyzpltk points out that Joker is motivated primarily to have sadistic fun. This is why he keeps Superman alive; to have fun with him. If he becomes bored of his powers, he will forfeit them. This is the case when Superman points out that Joker is unable to erase Batman from existence because Joker's life would then become meaningless. While Joker can kill Batman; he is unable to erase him from existence. So long as Joker remembers Batman (and since Joker will never forget Batman), Batman will continue to exist. After this epiphany, Emperor Joker lost his powers.
  • After losing his powers; Joker's mentality is shattered. He spent this aftermath curled up and drooling on the floor saying his name backwards 'Rekoj Rorepme'.



Joker/Mask is the Joker having acquired the Mask of Loki, the source of power of the character, the Mask. In this form, the Joker’s power is nearly unlimited, and was only defeated by Batman, who was able to convince the Joker that he was no longer funny in this form, but was merely relying on a “tired schtick.” The Joker was able to find the willpower in himself to pull the Mask from his face.


  • Joker is directly inspired by the 1928 silent film, The Man Who Laughs.
  • Joker has an unknown alias, although it is likely Jack Napier as stated in the animated series.
