The Joker

"No, no, no! You were supposed to DIE when the clown exploded!"

- Mortal Kombat vs. DC Universe

The Joker is a fictional character, a comic book supervillain that appears in the pages of DC Comics. One of the many DC characters chosen to appear in the crossover video game Mortal Kombat vs. DC Universe, he is arguably DC's most well known antagonist. With The Joker's reputation for unmatched sadism and maniacal homicidal tendencies, his counterpart in the crossover game is Kano.

About The Joker
Because of his chronic and deeply seeded 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 man with a pregnant wife, down on his luck and trying to make money as a stand-up comic. Not able to make ends meet, he is recruited by a group of career criminals to assist in a heist at a 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, one of the criminals is killed by gunfire from a police officer, and one escapes, leaving the man in the Hood alone.

It's then that Gotham's nocturnal avenger, the Batman descends on him on a catwalk. 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 stretched into a rigor mortis smile. 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 have plagued Gotham City and Batman in the years since.

MK vs. DC
The Joker escaped from Arkham Asylum and fled into Gotham until he was confronted and defeated by Batman. However, when Batman was distracted fighting Liu Kang, The Joker escaped. As he was running, he encountered Scorpion, who defeated the Joker in combat. Lex Luthor recruited the Joker with Catwoman and Deathstroke and his team of villains. Luthor dispatched Joker to find the teleportal that would send them back to Apokolips along with Deathstroke.

They meet Sonya Blade and Kano and fought,The Joker took on Sonya while Deathstroke took on Kano. The Joker defeats Sonya and pushes Deathstroke aside and takes on Kano himself and defeats him too. The Kombat Rage gets to him and he betrays Deathstroke, defeating him too. He takes on his old archnemesis Batman, believing to be able to defeat him also, but loses to Batman as the Dark Knight uses his taser.

In the final battle between the DC universe heroes and The Mortal Kombat warriors the Joker fights again Kano.

Biography

 * 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."

Powers and abilities
Although The Joker is a human man with no supernatural enhancements, natural or otherwise, his lack of sanity and rationality have themselves been a fatal weapon to his many, many victims as he is unencumbered by rational thought and is therefore extraordinarily creative, if not vindictive and sadistic. This has translated to his many schemes over the years, as well as in his hand-to-hand combat style. Although Joker prefers to have henchmen do the "dirty work" for him, having a resourceful nemesis like Batman has forced Joker to be able to fight hand-to-hand in situations that force him to. Sometimes using weapons that play off his clownish appearance, many times Joker prefers stabbing weapons and firearms, and always attempts to use his methods of killing in ways that he finds ironic and humorous.

The winner will face off against the Joker himself."

Trivia

 * The Joker is one of the two only 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 down. He does this by stomping on their groin. This cannot be prevented, and always happens when a fatality is not performed.
 * His Fatality, the Killing Joke, is named after the oneshot comic showcasing a psychological battle between him and his archnemesis, Batman, whilst detailing pieces of his life before turning into the Joker.
 * 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 Shao Kahn. Interestingly, the announcer in Mortal Kombat 2011, who is presumably Shao Kahn, is voiced by Kevin Michael Richardson, who provided the voice of the Joker in The Batman
 * In the DC Storyline, The Joker references Star Trek 2: The Wrath of Khan. After hearing the news of Dark Kahn, he looks up and the sky, and yells "KAHN" similar to Captain Kirk.
