The Joker is an infamous crime boss in Gotham City and a known enemy of the vigilante known as the Batman. He is the former partner and lover of Harley Quinn, and murdered Robin, the Batman's partner.
Murder of Robin
A young Joker had a run-in with Batman's unidentified partner, the vigilante known as Robin. Robin did not survive the encounter. When Batman discovered that Todd had died, he found his scorched Robin uniform with the words "HAHAHA! Joke's on you, Batman!" painted across the chest piece. Enraged, Batman found Joker and severely physically beat him, causing damage to his teeth. As a result, Joker placed metal fillings on his broken teeth.
Joker was thrown into Arkham Asylum, where he met Dr. Harleen Quinzel, a new psychiatrist who quickly fell in love with him through their sessions together. Joker used her to procure a machine gun, allowing him to take control of the institution. He rewarded her naivete with shock therapy, as punishment for erasing "what few memories he had left", before escaping.
After being freed, Joker put Harleen through a series of test and trials only to be annoyed by her trying to make him fall in lover with her. He went on to tell her that he is not someone to be loved and that she is not a part of his plans. As a final test, Joker brought Harleen to the Ace Chemicals building, where he pushed her to proved her devotion with the ultimate test. Joker watched her consign herself to a vat of chemicals and was about to walk away and abandon her to her own death, only to reluctantly have a change of heart, and jump in after her. Once emerged, he embraces the newly born Harley Quinn with a kiss and a hearty laugh.
Joker and Harleen arrived at a club to meet with its owner about business. All went well, until the owner had his eyes on Harley, which angered the Joker into shooting him clean in the head. After leaving the club in his car, the two were chased by Batman across Gotham. In a last ditch effort to escape, Joker drove the car into the ocean as he made his escape; leaving Harley to drown if not for Batman coming to her aid.
Joker had become miserable without her and has been obsessively searching for her whereabouts, until he was informed of her being held in Belle Reve prison. He kidnapped one of the employees of the jail and had him deliver a phone to her in preparation to break her free.
Infiltrating a company owned by Wayne Enterprises, Joker gained access to the one of the scientists responsible for manufacturing the microscopic bombs utilised by Amanda Waller.
Joker commandeered a helicopter to extract Harley from the Suicide Squad after the bomb in her neck was deactivated. The rescue was brief as the helicopter was shot down with Joker inside after he pushed Harley from the aircraft onto a rooftop.
Harley was returned to Bell Reve upon completion of her mission, but it soon fell under siege by Joker and his men in another rescue attempt. This one was successful, and Harley made it out with her lover.
Joker and Harley would later become mutually estranged under circumstances that were not divulged in detail. The resulting situation would lead to Quinn being targeted by other criminals, namely Roman Sionis, on account of no longer benefitting from the Joker's protection.
This section of the history covers the events of the 2021 director's cut Zack Snyder's Justice League. Part of this contradicts the cinematic release of the 2017 movie Justice League. All or part of this section may no longer be valid for the rest of the DC Extended Universe.
Within an apocalyptic scenario dreamt by Bruce Wayne, the Joker was shown as a member of Batman's resistance against the regime of an evil Superman under the control of Darkseid. A joker playing card was used to symbolize their highly tenuous truce, and when Joker alluded to the death of Robin, Batman referred to the death of this timeline's Harley Quinn, who died in his arms while asking him to kill her former lover slowly and painfully, which Batman said he would honor, briefly leaving the Joker shaken before he dismisses the idea. This Joker was last seen laughing maniacally as the group was suddenly confronted by Superman himself.
- Unique Physiology
- Cheating Death: Joker proved himself capable of escaping alive and healthy from more than one potentially fatal situation; He appeared after being seen in a burning helicopter after it was shot down and crashed into a building with no visible injury.
- Tactical Analysis
- Escapology: he was shown to have easily escaped from a car he speedily drove into a river.
- Mental Illness: Joker seems to have a warped and twisted sense of thinking. He considers himself an idea, or a mindset of chaos who executes his will according to his plan. He also displays his love for Harley in a very manipulative and possessive, although sometimes apparently uncaring, manner, but will actually go to desperate lengths to get her back.
- This version of the character is exclusive to the continuity of the DC Extended Universe and is an adaptation of Joker. The original character was created by Bill Finger, Bob Kane, and Jerry Robinson and first appeared in Batman #1.
- Joker is played by Jared Leto.
- Leto was the only actor to join the cast of Zack Snyder's Justice League specifically for footage newly shot for its release, not having been part of the film as originally planned. Snyder arranged this for the sake of having the character share a scene of direct interaction with Ben Affleck's Batman.
