"Just wait 'til they get a load of me."
―The Joker to Johnny Cage

The Joker is a supervillain and arch-nemesis of Batman. The Joker was one of the many DC characters chosen to appear in the crossover video game Mortal Kombat vs. DC Universe. With the Joker's reputation for unmatched sadism and maniacal homicidal tendencies, his counterpart in the game is the mercenary Kano. The Joker returned to the franchise in Mortal Kombat 11 as a downloadable guest character.


Because of his chronic and deeply seated insanity, there is no definitive story of how the man who would become the Joker came to be. There are, however, a few prevailing versions of what could be his origin story.

The most well-known of these is about a chemist with a pregnant wife, down on his luck and trying to make money as a stand-up comedian after being laid off from his job at the chemical company. Not able to make ends meet, he is recruited by a group of career criminals to assist in a heist at his former chemical plant using the traded off guise of the Red Hood. Right before the job was to be carried out, the man learns that his wife and unborn child were killed in a fire at their apartment. Feeling hopeless, the man agrees to the job and breaks into the chemical plant with the criminals as the Red Hood. Coming under fire, both of the criminals are killed by gunfire from police officers, leaving the man in the Hood alone.

It's then that Gotham's recently-established nocturnal avenger, the vigilante known only as the Batman, descends upon him on one of the chemical plant's catwalks. Cowering from him, the man loses his footing and falls into a large vat of chemicals before Batman can save him. Washing ashore, the man feels burning in his face and eyes. Discarding the hood, the man looks at his reflection in a puddle of rain and sees his skin bleached white, his hair turned emerald green, and his mouth unnaturally stretched into a rictus grin. The man begins crying, then giggling, and suddenly bursts into laughter, driven irredeemably insane by one bad day and a horrible disfigurement. From then on, the Joker's brilliantly sadistic and reprehensible actions would plague Gotham City at-large for years to come, with his murderous, unpredictable formability causing him to become Batman's chief adversary in the vigilante's war on crime.

Mortal Kombat vs DC Universe

The Joker first appears in Gotham City, ambushing Batman by throwing an exploding clown doll on the hood of the Batmobile. Batman easily survives the explosive, frustrating the Joker, who decides to fight Batman himself. He is easily defeated and quickly surrenders, getting cuffed by Batman.

However, when Liu Kang mysteriously appears, the Joker escapes as Batman investigates. Sometime later, the Clown Prince of Crime encounters Scorpion, who is searching for Kitana. When Scorpion walks away after becoming annoyed by the Joker's antics, the Joker strikes him with an extending boxing glove, prompting a fight with the enraged spectre. Scorpion easily defeats the Joker in combat but spares his life out of disgust.

Moments after his defeat, Lex Luthor appears and recruits the Joker onto his team of villains alongside Catwoman and Deathstroke. The Joker is present with them when they go to Metropolis and meet up with Captain Marvel and learn of Dark Kahn and his connection to Apokolips. Luthor dispatches the Joker and Deathstroke together to find the portal in the Mortal Kombat universe that would allow them to go to Apokolips.

During their mission, the Joker and Deathstroke encounter Sonya Blade and Kano in the Graveyard in the Mortal Kombat Universe, and Joker damages Sonya Blade's communicator with a spray of acid from a fake flower, the damage done to the device teleporting all of them to Oa. While Deathstroke battles Kano, the terrified Joker faces Sonya. Much to his own surprise as well as Deathstroke's, the Joker defeats Sonya, and becomes fueled by the Kombat Rage infecting their worlds.

Arrogant over his victory, the Joker shoves Deathstroke aside and challenges Kano himself, defeating him. Deathstroke is able to return himself and the Joker to the graveyard, but quickly realizes something is wrong with the Joker. The Joker then declares his intentions to allow the universes to be destroyed and his ultimate goal of killing Batman. Joker betrays Deathstroke and battles him, defeating him too. Believing himself unstoppable, he decides to finally confront Batman.

He lures his old arch-enemy into a trap by calling him out to Gotham and confronts him in the streets, defeating him as well. As he is celebrating, he is tasered by the Dark Knight and is easily dispatched. The Joker is next seen among the gathered heroes and villains at the Special Forces base as they prepare to take on Dark Kahn.

In the final battle between the DC universe heroes and the Mortal Kombat Kombatants, the Joker fights against Kano but is ultimately knocked out. Joker later witnesses the DC Universe's restoration.

Moves and Abilities

Although the Joker is a human with no particular enhancements, natural or otherwise, his lack of sanity and rationality have often been a fatal weapon for his victims: he is unencumbered by rational thought and is therefore extraordinarily creative, vindictive and sadistic. This has translated into his many schemes over the years, as well as in his hand-to-hand combat style. Although the Joker prefers to have henchmen do the "dirty work" for him, having a resourceful nemesis like Batman has forced him to be able to fight hand-to-hand in situations that force him to. Sometimes using weapons that play off his clownish appearance, he also makes use of stabbing weapons and firearms, and always attempts to use his methods of killing in ways that he finds ironic and humorous.

As a result of Dark Kahn's Rage, the Joker has become both stronger and faster than he would normally be otherwise, allowing him to hold his own against and defeat skilled fighters, such as Sonya Blade, Kano, Deathstroke, and Batman.

  • Throw (Forward): The Joker grabs his opponent and equips his extend-o boxing gloves and punches the opponent with one of them to knock them down, then delivers two blows to the groin with the other one and punches them in the groin with both gloves, pushing them away.

A sign with the word “FRIENDSHIP” in balloon letters and confetti appears out of nowhere and the opponent looks at the cake, revealing a fuse instead of a candle. The cake explodes and blows off their forearms while launching them into the air, causing the Joker to pull out a brightly colored Tommy gun and shoots at the opponent, knocking off the lower half of their leg in the process while the balloons are popped (revealing the words “FATALITY” in red paint) and a string is cut in the process. When they land, the last string rips and the sign is dropped onto the opponent’s body, cleaving them in half. (MK11)
  • Pop Goes The Mortal: The Joker, whilst singing one of two songs to the tune of "Pop Goes The Weasel", takes out his extending boxing glove and punches a hole through his opponent's torso.

But as luck would have it, I had just the gizmo to find them. And oh, how the Hourglass spoiled me! Havik and I are going to be bosom buddies. And what's that? My new pal knows an entire realm dedicated to law and order? And he exists only to disrupt it? Well I say, he and I need to get busy! Meet the League of Misunderstood Maniacs!

Mortal Kombat vs. DC Universe

  • The Joker is one of the only two fighters in the MK vs. DC Universe game that laugh when under the influence of rage. The other is Catwoman.
  • His Fatality, The Killing Joke, is named after the one-shot comic.

  • Joker's ending has him turning into the DC Universe's equivalent of Shang Tsung or Shao Kahn.
  • In the DC Storyline, The Joker references Star Trek II: The Wrath of Khan; after hearing the news of Dark Kahn, he looks up at the sky, and yells "Kahn!", similar to Captain Kirk.
  • His ending is a nod to the "Emperor Joker" storyline where he stole Mister Mxyzptlk's power to create the world in his own image. This is referenced during an interactions with Kitana in Mortal Kombat 11.

Mortal Kombat 11

  • During Cassie Cage's Social Media Intro, Cassie Cage will receive a text Cassie saying "Why is Raiden so Serious?", which she responds with "Deep down he's (Joker Card Emoji)". This is a reference to both The Dark Knight and that Raiden's voice actor is also Richard Epcar.
    • Similarly, one of Joker's opening interaction with Sonya has him ask her "Why so serious, army girl?"
  • One of the Joker's intros has him cutting his thumb with his own knife and then drawing a smile on his face with his own blood, a reference to the film Joker. One of Joker's brutalities is named "Send in The Clowns", a reference to the Stephen Sondheim song featured in the film.

This is a reference to the character of the same name from the Hanna-Barbera Superfriends series and his later supporting role in the Adult Swim animated series, Harvey Birdman Attorney at Law.
  • When interacting with both Jacqui Briggs and Kotal Kahn, the Joker complements them under allusions to two DC characters (Vixen and Aquaman, respectively). This is a reference to their actors, Megalyn Echikunwoke and Pil LaMarr, portraying the characters in other media, including the Injustice video games.
  • During opening interactions with Spawn, Joker will be told "Your Angel of Death awaits..." This is a reference to Batman: Mask of the Phantasm, where the titular character says the same line to him.
