—The Joker to Jax in Mortal Kombat 11

The Joker is a Human supervillain known for his appearance in DC Universe in both comics and media. He is most famously known as the arch-nemesis of Batman, is arguably DC's most well-known antagonist, and is widely regarded as one of the greatest fictional characters ever created.

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 crossover game is the mercenary Kano.

The Joker returned to the Mortal Kombat franchise in Mortal Kombat 11 as a playable guest character, being the fifth character available in the Kombat Pack. The Joker later reappears as a playable character in Mortal Kombat Mobile.

About The Joker

Due to his chronic and deep-seated insanity, there is no definitive answer to the Joker's backstory; even the Joker himself claims that he never remembers it the same way twice, and that he doesn't know his own real name. There are, however, a few versions of what could be his origin story.

The most well-known of these portrays the Joker as a chemist with a pregnant wife. After leaving his job at the Ace Chemical Processing Plant, the chemist tries to make money with his dream job: stand-up comedy, though he is unable to make enough money to support his family. Desperate for money, he agrees to help two criminals break into the chemical plant he left, doing so in a disguise, and under the name "Red Hood", though his wife convinces him to back out at the last minute. However, just as he meets with the criminals to refuse the job, the police tell the man that his wife and unborn child, suspected to be a boy, were killed in a fire at their apartment. 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 as the sole survivor.

It's then that Gotham's recently-established nocturnal avenger, the vigilante known as the Batman, descends upon him on one of the chemical plant's catwalks, investigating the situation. Terrified, the man tries to back away, only to lose his footing and fall into a large vat of chemicals before Batman can save him. He washes ashore a while later, his face and eyes burning. Discarding the hood, the man looks at his reflection in a puddle of rain and sees, to his horror, that his skin has turned bleach white, his hair turned emerald green, and his mouth unnaturally stretched into a permanent 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 formidability causing him to become Batman's chief adversary in the vigilante's war on crime.


  • MK vs DCU: "An insanely homicidal super-villain, the Joker's white skin, green hair, and blood-red lips belie the chaotic nature underlying his cartoonish appearance. The self-styled "Clown Prince of Crime" has no superpowers, beyond a capacity for incredible violence and a skill at creating deadly mayhem. He frequently concocts elaborate schemes to entrap his arch-nemesis, Batman."
  • Mortal Kombat 11: "Unpredictable, violent and incredibly dangerous, The Joker is chaos personified. He’s killed a Robin, crippled Batgirl and tortured and murdered countless people throughout the DC universe. And now, he’s the latest Kombatant to join in Mortal Kombat."


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. Some time 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.

Combat Characteristics

Powers 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 in single-combat when he is forced to. While he mostly uses weapons that play off his clownish appearance, he also makes use of stabbing weapons and firearms, and always attempts to murder 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 expert martial artists, such as Sonya Blade, Kano, Deathstroke, and Batman.

Special Moves

  • Joker's Wild: The Joker throws a playing card lined with steel at the opponent. (MKvsDCU)
  • Sinister Heels: The Joker grabs the opponent and kicks them repeatedly with the back of his foot. (MKvsDCU)
  • Put It There Pal!: The Joker counters an opponent's attack by grabbing their hand and shocking them with his electric joy buzzer. He then laughs giddily and dances in a circle. (MKvsDCU)
  • Bombs Away: The Joker throws a bomb with a smiley face on it that bounces up and down before exploding. He can throw the bomb at close and long-range. (MKvsDCU)
  • Magic Trick: The Joker is enveloped in a cloud of green smoke. Any button which is pressed in this brief state will produce a different attack. (MKvsDCU)
    • Surprise Stomp: The Joker does a flying jump kick.
    • Surprise Slide: The Joker does a sliding kick across the ground.
    • Surprise Bomb: The Joker appears from the mist with a bomb in his hand.
    • Surprise Pistol Whip: The Joker smacks the opponent with a pistol.
  • The Funnyman: The Joker laughs as he dances in a circle, causing his rage meter to fill. (MKvsDCU)
  • Punching Bag: The Joker pulls out an extend-o boxing glove and fires it, stretching over half the field. It is possible to strike the opponent twice with this technique, as pulling out the glove will cause damage to the opponent if they are close enough before the Joker extends the glove for the actual strike. (MKvsDCU)
  • Batsy-Poo: The Joker takes out a Batman doll and fires a hidden gun from inside its mouth, knocking the opponent away. The attack can be delayed. Doing so also makes the Joker have a conversation with the doll. (MK11)
    • Amplifying the attack has the Joker place a firework rocket on the barrel of the hidden gun inside Batsy's mouth, sending the rocket at the opponent, where, if it successfully hits, it will deal increased damage and launch the opponent into the air for a juggle.
    • Batsy-Poo Cancel: The Joker gains the ability to cancel the attack, where he tosses Batsy away. Canceling the attack does not require any Offensive or Defensive Meter to cancel, however, the Joker is completely vulnerable while he tosses Batsy away. (MK11 - Equip Ability)
  • Birdboy Beatdown: The Joker charges forward and smashes the opponent on the head with his cane, bringing them down to their knees, after which he winds his cane back, then smacks the opponent horizontally across the face, knocking them away. (MK11)
    • Amplifying the attack has the Joker beat the opponent over the head three times additional times, with the final swing knocking the opponent to the ground and dealing slightly increased damage.
    • If the Joker connects three amplified Birdboy Beatdowns during the match, the attack turns into a Krushing Blow the next time it is used, with the Joker smashing the opponent in the temple with the cane, dealing over double the original damage.
      • This Krushing Blow damage can be increased slightly if the opponent is under the effects of Getting Lit.
  • C C D D E G E C: The Joker pulls out a jack-in-the-box with a giant spring clown head popping out, damaging the opponent if they are too close or if the clown head hits them first before it can bounce off the ground. The Joker can delay when he wants to release the clown head, where he winds up the jack-in-the-box, allowing him to travel almost halfway across the arena. Delaying also allows the Joker to reach the opponent at full-screen distance. This attack is considered a projectile. This attack has armor breaking properties, ignoring the armor granted by specific abilities and Fatal Blows. When breaking the armor of a Breakaway, the attack will deal slightly increased damage and launch the opponent into the air. When breaking the armor of a grounded opponent, this juggle effect is still present, however, the window for additional attacks is reduced. (MK11)
    • Amplifying the attack has the clown head continuously bounce, where it travels the entire fightline until making contact with the opponent. If this is successful, the attack will deal increased damage and knock the opponent away. Like the original, this version also has armor breaking properties, and when breaking armor, the attack now launches the opponent high into the air for a juggle, regardless if this is used on a grounded, armored opponent or from a Breakaway. In addition, the attack deals slightly increased damage when breaking the armor of a Breakaway.
  • KAPOW: The Joker pulls out two extend-o boxing gloves and hits the opponent four times, knocking them away. When blocked by the opponent, this attack creates considerable pushback. This ability requires two ability slots and replaces Birdboy Beatdown when equipped. (MK11 - Equip Ability)
    • The amplified version is called BAM POW ZAP and replaces the final punch with a double axe handle strike with the gloves, bouncing the opponent off the ground for a juggle. Amplifying the attack causes it to deal slightly less damage at the expense of bouncing the opponent off the ground for a juggle.
    • If the Joker connects the attack as a Kounter or a Punish from the maximum distance, the attack turns into a Krushing Blow, with the brass knuckles on the glove crushing the front part of the opponent's skull inwards, dealing over double the original damage.
      • This Krushing Blow damage can be increased slightly if the opponent is under the effects of Getting Lit.
  • Batsy Pew Pew: The Joker sets Batsy on the ground where he fires a shot at the opponent's shins, causing them to stumble backwards. (MK11 - Equip Ability)
    • Amplifying the attack has Batsy fire three more shots at the opponent's shins, dealing over double the original damage and knocking the opponent off their feet.
  • Puppet Parry: The Joker pulls Batsy while mocking the opponent in Batman's voice saying one of Batman's catchphrases, where he parries basic attacks and specials, with the exception of Low attacks and Fatal Blows. When parrying the opponent, the Joker hits the opponent across the face twice with Batsy before shooting the opponent in the face with Batsy's hidden gun, knocking them to the ground. This ability conflicts with Getting Lit when equipped, disabling the option to select Getting Lit. (MK11 - Equip Ability)
    • Amplifying the attack has the Joker uppercut the opponent with Batsy, launching them into the air for a juggle. This version of the attack deals less damage than the original at the expense of launching the opponent into the air for a juggle. Additionally, if this is successful, the Joker cannot perform his One Bad Day combo after launching the opponent.
  • Getting Lit: The Joker pulls out a canister of gasoline, begins pouring gasoline onto the fightline, then lights it on fire with a match, damaging the opponent and creating a damage-over-time effect on the fightline for some time. Unlike most damage-over-time effect-like attacks that are placed on the fightline, the opponent can dash through the flames to avoid the damage. The Joker can extend the attack, allowing him to pour more gasoline and, in turn, cause more fire on the fightline. The Joker can light about half the arena on fire doing this to create the damage-over-time effect. The Joker must wait for the flames to extinguish before he can perform this attack again. Connecting or being struck by a Krushing Blow or Fatal Blow ends this effect prematurely. This ability conflicts with Puppet Parry when equipped, disabling the option to select Puppet Parry. (MK11 - Equip Ability)
    • Amplifying the attack has the Joker throw the canister into the flames to create a fiery explosion that launches the opponent into the air for a juggle.
  • Corpse Trot: A hostage in a wheelchair rolls onto the fightline behind the Joker, where the Joker grabs the victim by the legs and swings their body at the opponent three times, where they explode on the final swing, knocking the opponent away. When used in the corner of an arena, this attack can allow a brief moment of combo extensions; otherwise, the opponent is knocked away. The final explosion of this attack is a High, which can miss ducking opponents when timed correctly, leaving the Joker vulnerable, however, the Joker is safe if the opponent blocks the attack. This ability requires one ability slot and replaces C C D D E G E C when equipped. (MK11 - Equip Ability)
    • Amplifying the attack has the Joker slide the victim underneath the opponent, where the victim bursts into flames shortly after, dealing increased damage and knocking the opponent off their feet.
  • Jack In The Box: The Joker pulls out a jack-in-the-box and kicks it towards the opponent's feet, where, after a moment, a giant spring clown head pops out, briefly knocking the opponent into the air for a juggle. The Joker is completely vulnerable when pulling out the jack-in-the-box, and if he is successfully hit, the spring clown head will not pop out. However, the Joker is extremely safe if the opponent blocks the attack. The attack can be used at ranges, called Close Jack In The Box and Far Jack In The Box, respectively. This ability requires two ability slots and conflicts with Hostage Hop when equipped, disabling the option to select Hostage Hop. (MK11 - Equip Ability)
    • Amplifying the attack has the spring clown head explode after popping out, dealing increased damage and launching the opponent high into the air for a juggle. Like the original version, the Joker is completely vulnerable when pulling out the jack-in-the-box, and if he is successfully hit, the spring clown head will not pop out. However, the Joker is extremely safe if the opponent blocks the attack.
  • Hostage Hop: The Joker pulls out a detonator, and a tied-up person wearing a paper bag on the head and a Joker suit starts hopping towards the opponent while the Joker attempts to press the button. Once he detonates them, the hostage's head explodes, and then the rest of their body, launching the opponent into the air for a juggle. The Joker is extremely safe if the opponent blocks the attack. When the hostage's head explodes, the attack is considered a projectile, however the explosion from his entire body is not. This ability requires two ability slots and conflicts with Jack In The Box when equipped, disabling the option to select Jack In The Box. (MK11 - Equip Ability)
    • Amplifying the attack has the hostage's entire body explode immediately while retaining the same properties, however if offers no additional damage.
  • BOING: The Joker uses his boxing gloves to propel himself into the air, allowing him to get closer to his opponent. While propelling himself into the air, the Joker can perform airborne attacks. The attack can be used at different ranges, called Close/Far BOING, respectively. (MK11 - Equip Ability)
  • Jumping Jester: The Joker sets a jack-in-the-box on the ground with a giant spring clown head popping out, briefly launching the opponent into the air for a juggle, however this window is extremely small. The attack can be used at different ranges, called Close Jumping Jester and Far Jumping Jester, respectively. (MK11 - Equip Ability)
    • Amplifying the attack has the clown head knock the opponent high into the air for a juggle, however the damage output is the same. Additionally, if the spring clown head does not damage the opponent when it pops out, it can now damage them when flying towards the ground. This damage output remains the same.

Fatal Blow

  • SMILE: The Joker will start winding up a jack-in-the-box. If the opponent gets caught, he brings out his knife and stabs the opponent's back repeatedly. He then brings out another knife and uses both to slash both the opponent's cheeks. He then hits his opponent from behind five times with his cane, as blood splatters all over the screen. (MK11)

Other Moves

  • Free-fall Super Move: The Joker pulls out his extend-o boxing glove and fires it, punching his opponent. (MKvsDCU)
  • 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. (MK11)
    • If Joker does not connect with his Fatal Blow and the throw connects during the cooldown period, the attack turns into a Krushing Blow, where the boxing gloves crush the male opponent's testicles or damage the female opponent's pelvis, dealing over double the original damage.
      • This Krushing Blow damage can be increased slightly if the opponent is under the effects of Getting Lit.
  • Throw (Backwards): The Joker hooks the opponent in the side of their face with his cane, spins them around to the opposite side, where he pulls out Batsy and shoots them 8 times, point blank in the face to knock them away. (MK11)
  • Show's Over: The Joker pokes forward with his cane, follows up with an overhead smash and finishes with an uppercutting swing, knocking the opponent away. (MK11)
    • If this combo is performed on the opponent as a Kounter or Punish, the combo turns into a Krushing Blow, where the Joker's cane crushes the front part of the opponent's skull inwards, dealing increased damage and sending the opponent into the air for a juggle.
      • This Krushing Blow damage can be increased slightly if the opponent is under the effects of Getting Lit.
  • Grand Entrance: The Joker hops forward with his leg outstretched and brings the cane down on the opponent's head, knocking them to the ground. The combo can not be performed in its entirety if the first strike of this combo is Flawless Blocked by the opponent. (MK11)
    • If only the second hit of the combo connects, whether the opponent successfully blocks the first hit and not the second or the second strike lands on its own, the combo turns into a Krushing Blow, where the Joker's cane crushes the top of the opponent's skull, dealing increased damage. The Joker is offered a moment of a special attack if this is successful. This Krushing Blow can not be triggered on opponents left open for a free hit by interactables.
  • Harlequin Of Hate: The Joker smacks the opponent upside the head with his cane before grabbing a hostage that was wheeled onto the fightline in a wheelchair and smacking the opponent with their body before tossing the victim's entire body at the opponent, knocking the opponent away full-screen distance. When the Joker throws the victim at the opponent, the combo is considered a projectile. (MK11)


  • The Killing Joke: The Joker takes out a gun and shoots it, but instead of a bullet, some confetti and a flag with the word "Bang" on it pop out of the barrel. He drops it and starts to laugh, before pulling out a real gun and shooting the opponent in the head, killing them. (MKvsDCU)
  • Card Trick: The Joker takes out four cards and throws three at the opponent's body. Then he throws the last one to the opponent's head, which knocks them to the floor, dead. (MKvsDCU)
  • Party Pooper: The Joker pulls out a cake and hands it to his opponent. 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 shoot at the opponent while laughing maniacally, knocking off the lower half of their legs 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 drops onto the opponent’s body, cleaving them in half. (MK11)
  • Pop Goes The Mortal: The Joker takes out his extending boxing glove and punches a hole through his opponent's torso. He then saunters over while holding a jack-in-the-box, places it in the open wound, and turns the crank. After a short pause, the jack-in-the-box activates, tearing the opponent's head away from their body. (MK11)
    • While performing this Fatality, the Joker will sing one of two morbid renditions of "Pop Goes the Weasel", hence the Fatality's name:
      • Version 1:
        • Bats would say that I’m a bad boy / To kill without a reason / But bodies stacked high never gets old / Blood's always in season!”
      • Version 2:
        • The fight is done and now’s the time / To bring it to a crescendo / Crank the knob and what will I get? / Your head as a memento!


  • The Klassic: Joker performs an uppercut, decapitating the opponent with a rising swing of his cane with their spine still attached. (MK11)
  • Playful Puppet: Joker performs a Puppet Parry and starts to continuously beat the opponent's head with a puppet until their head explodes. (MK11)
  • Deep Cuts: The Joker performs his Throw (Forward), placing the opponent in a wheelchair. After that, the Joker turns the wheelchair around and cuts the opponent's throat with a knife. (MK11)
  • Batter Up: Joker performs an amplified Birdboy Beatdown, only this time, he spits on his hands and readies himself for a final swing, before saying "Smile!" as the opponent says one final word or phrase, with the Joker knocks their head off towards the screen with a home-run swing. (MK11)
  • Together Forever: Joker performs a Getting Lit, leaving the opponent on fire while he "pours" confetti on himself from the same canister. When only a charred body remains of the opponent, Joker runs up and hugs the corpse. (MK11)
  • Magic Bullet: Joker performs a Batsy-Poo, blowing a hole in the opponent's head. (MK11)
  • Send in The Clowns: Joker performs a Hostage Hop, blowing up the opponent and the hostage to smithereens. (MK11)
  • Head Case: Joker performs an amplified C C D D E G E C, replacing the opponent's head with the Jack-in-the-Box's head. If Joker performs his Brutality Victory Pose winding up his Jack-in-the-Box after that, the opponent's head will pop out from it. (MK11)
  • Blam Blam Blam Blam: Joker performs his Throw (Backwards), continuously shooting at the opponent's face with Batsy's hidden gun until the frint of their face explodes. (MK11)
  • Rocket Power: Joker performs an amplified Batsy-Poo with the rocket impaling into the opponent's face, just to blow up their head afterwards. (MK11)

Other Finishers

  • Friendship - Come On Bats: The Joker laughs and throws his cane away, ready to kill his opponent with his revolver. However, he is stopped by a Batarang that hits him in the back of the head. After griping to the off-screen Batman, Joker produces a bunch of balloons as a half-hearted apology while occasionally glaring at the off-screen Dark Knight. (MK11)


  • MKvsDCU: "As the worlds separated, the Joker discovered he had retained his new powers. With them he soon controlled all of Gotham, proclaiming himself "Mayor Joker". Under his rule, the city devolved into chaos. He now holds a tournament in which "contestants" are forced to fight to the death for his amusement. The winner will face off against the Joker himself."
  • Mortal Kombat 11: "This was my dream vacation. I saw mayhem, mutilation. It was all a gas... for a while. But these nincompoops? They didn't really GET me. Not even that pretty boy, Ninja Mime. Good night, sweet prince! I'd 'finished' just about everyone worth finishing in Earthrealm and Outworld. Even lovable old Netherrealm. I was a lonely heart in search of new friends.

      • Of all the portrayals, only three live-action depictions have been given names, these being Jack Nicholson's portrayal from Tim Burton's Batman, known as Jack Napier, Cameron Monaghan's portrayal being known as Jeremiah Valeska in the TV series Gotham, and Joaquin Phoenix's portrayal being known as Arthur Fleck in Todd Phillips' film Joker.
    • The Joker's identity in video games is usually left unknown, similar to some of the cinema incarnations.
      • In the case of Anthony Ingruber’s portrayal from the duology of Batman video games published by the now-defunct Telltale Games, the Joker is jokingly known as John Doe, however, this is more as a nod towards the Joker's identity being unknown.
      • The Joker's identity in the Injustice series is also never revealed.
      • The Arkhamverse Joker is similarly mysterious in origin, and his attempts to use his Killing Joke backstories on Doctors Young and Strange are quickly debunked. Arkham Origins shows a flashback of Joker's past that resembles the events of The Killing Joke, along with Joker in the original Red Hood costume.

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.
    • Joker is also the only fighter to hit the opponent after they are defeated without a finisher. He does this by stomping on their groin.
  • His Fatality, The Killing Joke, is named after the one-shot comic showcasing a psychological battle between him and his archnemesis, Batman, whilst detailing pieces of his life before turning into the Joker.
    • It should be noted the chair in his ending resembled his chair in said comic.
  • The Joker is one of the two characters to have a special move that fills the Rage Meter and the only playable character to perform the move. The other is Dark Kahn, however, he is the unplayable boss.
  • In NTSC regions, The Joker's first Fatality, The Killing Joke, was mildly censored to keep with the Teen rating. However, in PAL regions, the Fatality is shown in full, including the death of his opponent.
  • 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.
    • This is later referenced by Johnny Cage in Mortal Kombat 11 if the player chooses Shao Kahn with Cage as an announcer.
  • 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 interaction with Kitana in Mortal Kombat 11.

Mortal Kombat (2011)

  • Although the Joker does not appear in the game, Shang Tsung uses an edited and more gruesome version of the Joker's The Killing Joke Fatality, however, the laugh Shang Tsung makes as the clown is the Joker's.

Injustice Series

  • The Joker is a playable character in both Injustice: Gods Among Us and its sequel Injustice 2, voiced by Richard Epcar, who has voiced Raiden in MKvsDCU, MK 2011, Mortal Kombat X, and more recently Mortal Kombat 11.
    • Richard Epcar also reprised his role as Raiden for his guest appearance in Injustice 2.
  • Despite being a completely different Joker from another universe, interactions with both Sub-Zero and Raiden reference MKvsDCU.
    • This is also true with other characters on the roster, with Batman even thanking Raiden for "coming back" as a support to defeat Brainiac.
    • Both Sub-Zero and Raiden will even mention Dark Kahn despite him not being a part of the Injustice Universe.
  • In Injustice 2, during a Clash with Black Adam, the Joker will ask "Meet that other lightning guy?" to which Black Adam will respond "With the bamboo hat? Yes.". This is a reference to Raiden's inclusion in the game as a playable guest character and his foreshadowing as a DLC character.
  • In Injustice 2, Raiden and Sub-Zero frequently assume some of the DC villains are agents of Shinnok during interactions, the Joker included.

Mortal Kombat 11

  • The Joker is the fifth DLC character in the game's Kombat Pack, with Richard Epcar reprising his role from MKvsDCU and the Injustice series.
  • The Joker's appearance in Mortal Kombat 11 looks strikingly similar to his voice actor, Richard Epcar. However, it was later revealed that Kenny Braasch serves as the facial model for the Joker.
  • Despite the references during interactions with characters, the Joker featured in the game is not the same Joker from the Injustice series, but rather the Joker from the crossover game Mortal Kombat vs. DC Universe.
  • During Cassie Cage's Social Media Intro, if she is fighting against Raiden, John Vogel will text Cassie saying "Why is Raiden so Serious?" to which she will respond with "Deep down he's (Joker Card Emoji)". This is both a reference to Raiden's voice actor, Richard Epcar, who voices the Joker in the Injustice series along with the Joker's inclusion as a guest character in MK11 and a reference to the 2008 Batman film The Dark Knight, in which the Joker, played by the late Heath Ledger, would occasionally say "Why So Serious?".
    • This was referenced again in an interaction with Sonya, where the Joker simply asks her "Why so serious, army girl?"
  • One of Joker's combos is named "Pale Moonlight", a reference to one of his lines in the 1989 Batman film.
  • With the release of The Terminator, Cassie Cage is given an outfit resembling the Joker's sidekick and lover, Harley Quinn. Alongside this, Johnny Cage has an award costume that resembles The Joker's attire as well.
  • 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. This is possibly a reference to the 2019 Joker film, where Arthur Fleck, now the Joker, stands among a crowd of rioters in Gotham, dancing and then smearing the blood on his own face into a smile.
    • One of Joker's Brutalities is named "Send in The Clowns", which is a song of the same name by Stephen Sondheim. The song was also featured in the 2019 Joker film, being played at the end credits.
  • The final moments of the Joker's Fatal Blow is a reference to the events of A Death in the Family where Joker kills Jason Todd, who is later resurrected as Red Hood, by beating him senseless with a crowbar in a warehouse before leaving him to die in a bomb explosion.
    • This is similar to his Super Move Not So Funny Is It? in Injustice 2, which is a direct reference to the death of Jason Todd, the second Robin.
    • This is referenced again with the special move Birdboy Beatdown, both how the Joker performs the attack and the name itself.
  • Joker's Arcade ending depicts Mileena, Hsu Hao, Havik and himself as members of the League of Misunderstood Maniacs. Hotaru also cameos in this ending, being stabbed by Mileena.
  • When previewing Joker's cane in the Kosmetic Kustomization, an ad will appear at the bottom right of the screen.
  • One of the Joker's special moves, C C D D E G E C, is named after the musical notes that are played in the popular English nursery rhyme "Pop! Goes the Weasel". The same notes are played while Joker winds up the Jack-in-the-Box during the move.
    • Joker also parodies the song during his Pop Goes The Mortal Fatality while performing the finisher: "Bats would say that I'm a bad boy / To kill without a reason / But bodies stacked high never gets old / Blood's always in season!" as well as another parody of the song: “The fight is done and now’s the time / To bring it to a crescendo / Crank the knob and what will I get? / Your head as a memento!”.
  • The Joker is the only character with a special attack whose amplified version actually has a name, this being his KAPOW special move, whose amplified name is BAM POW ZAP.
    • This is possibly a reference to the famous sound effect title cards in the 1960's Batman TV Series starring Adam West.
  • The Joker is the only character where the Fatality header does not appear during a Fatality, this being his Party Pooper Fatality. This is due to the wooden Fatality sign taking over for the gameplay version.
  • When interacting with Jade and Sheeva, they seem aware of the Joker's nuking of Metropolis, a reference to the Injustice series, stating they know of the Joker killing millions of people and knowing what he's done when entering the MK Universe.
    • This is possibly referenced again when interacting with Noob Saibot, where the Joker compares his kill count to Bi-Han's.
  • When interacting with Shang Tsung, the Joker will say that Shang Tsung "stole his face", a reference to MK 2011 where Shang Tsung parodied the Joker's The Killing Joke Fatality from MKvsDCU.
    • The line "Never rub another man's rhubarb" is also a reference to Batman (1989).
  • When interacting with Sonya, she claims to have had enough of him the first time. This is a reference to when Sonya and Kano fought Joker and Deathstroke in MKvsDCU.
    • Joker asks Sonya if she doesn't like losing in graveyards, though, when they actually fought each other, it was after the four of the characters transported to the Oan Senate.
  • When interacting with Nightwolf, the Joker mistakes him for Manitou Raven, which lead him to believe that he is an "Apache Chief". 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 that their actors portrayed.
    • The Joker mentions to Kotal Kahn that he knows a "King who talks to fish". This is a reference to both Kotal Kahn's voice actor Phil LaMarr and the character Aquaman that LaMarr voiced in both Injustice titles and the Young Justice animated series.
    • The Joker addresses Jacqui Briggs as a "vixen". This is a reference to Jacqui's voice actress, Megalyn Echikunwoke, who portrayed the DC heroine Vixen in several DC properties ranging from on camera to voiceover.
  • When interacting with Jax, he speaks about Jax's sacrifice, in which Jax says that he wants to serve and protect his family country. Joker then says he sounds like "that big, blue boy scout". This is a reference to Superman.
    • Another interaction with Jax has the Joker addressing him as "RoboCop" after Jax quotes the famous "Dead or alive, you're coming with me" line.
  • When interacting with Scorpion, the Joker asks him if he still has a headache, referring to the sneaky blow of the boxing glove he gave him during their first meeting in MKvsDCU.
  • When interacting with Kotal Kahn, Joker may mention Dark Kahn, although Kotal is unaware of who he is.
  • When interacting with Frost, the Joker brings up the villainess Killer Frost by saying "She's "killer" Frost" to her as Frost herself questions the Joker on him knowing another Cryomancer he knows.
  • When interacting with Spawn, he tells the Joker "Your Angel of Death awaits..." which is a reference to the 1993 film Batman: Mask of the Phantasm.
  • When interacting with Spawn, Spawn will usually react or show hatred towards the Joker. This is due to his arch-nemesis, Violator.
    • Spawn will respond to the Joker's comments in one of the interactions by saying "I fucking hate clowns".
  • In the Joker's Sudden Death Outro, the opponent is seen behind the Joker surrounded by dynamite, where the Joker fiddles with the detonator until the explosives go off unexpectingly. This makes the Joker the only character in the game that kills the opponent, regardless if he performs a Fatality or Brutality or not.
    • With this, in a technical sense, the Joker is the third guest character in the series to always kill the opponent after a match, the first being the Predator and the second being the Alien, both doing this in Mortal Kombat X.
    • This Outro itself is also a reference to a scene in the 2008 film The Dark Knight, where the Joker's detonator to blow up Gotham General malfunctions before unexpectingly going off and blowing up the hospital while the Joker messes with the detonator.
  • The Joker is one of four characters with an Intro or Outro that breaks the 4th wall, this being both his Jump Scare Intro and his Graffiti Artist Outro. The others who break the 4th wall are Johnny Cage, RoboCop and Mileena.

Mortal Kombat Mobile

  • With the release of the Twisted Tower, the Joker made his playable debut in Mortal Kombat Mobile, the Tower itself being themed after him and a chance of rewarding his Diamond card for completing it.
  • The Joker, along with Jason Voorhees, Freddy Krueger, Leatherface, and the Terminator are all Diamond cards, thus making all guests in the mobile game Diamond Cards.
    • The exception of this is Jason's Slasher and Unstoppable cards, which are Gold, however, Jason's Nightmare card is Diamond.
  • The Joker is the second character to be affiliated with the Nomad Class, the only other card to be affiliated is Black Dragon Erron Black.

Mortal Kombat 1

  • The Joker is mentioned during Arcade interactions in Mortal Kombat 1.
    • When Liu Kang interacts with himself, he will say that "An evil clown tricking him into taking Kitana's life", referencing Superman's dark turn in the Injustice series.
    • An interaction between Peacemaker and Liu Kang has the Fire God reveal inhabitants from Peacemaker's universe have been in his universe, stating the Joker was the worst of them all.
      • Interestingly, the Joker that Liu Kang is mentioning is not actually from Peacemaker's timeline.
    • An interaction between Havik and Peacemaker has the vigilante mock Havik, calling him The Joker and Two-Face's illegitimate child.


  • When fighting Kronika in the game's Story Mode as Fire God Liu Kang or Shang Tsung, it is possible she will call upon the Joker to fight for her when using her Duplicate Fighter Ability despite him being a non-canon downloadable guest character. This can occur with every guest character.[1]
  • In MK11, when the Joker performs the amplified version of Puppet Parry, his cane appears out of thin air. This is because the attack takes the last hit of the Joker's One Bad Day combo.
  • In MK11, if the Joker is struck by an attack just before he lights the gasoline line on fire during his Getting Lit special attack, the canister will not disappear, rather, it will be stuck to the Joker's hand for some time before disappearing.
  • In MK11, on rare occasions when using Birdboy Beatdown, the opponent will not suffer from the attack's normal animation, rather they will stand in place before getting knocked away.
