DC Universe. Harleen Quinzel was a psychologist at Arkham Asylum, and after meeting the Joker, she became his frequent accomplice, took on the name Harley Quinn, and got into an abusive codependent relationship with him.
The Joker's most famous romantic partner is definitely Harley Quinn. Together, they were two peas in a pod, at least until it all came crashing down. Harley Quinn got her start with the Joker when she became his psychiatrist at Arkham Asylum.
A female version of the Joker appeared as part of DC's Tangent Comics line in her own one-shots (Tangent Comics: The Joker #1 in 1997 and Tangent Comics: The Joker's Wild! #1 in 1998). This Joker bore little resemblance to the traditional interpretation of the character and instead was modeled on Duela Dent.
While intended to appear in one episode, Quinn became a recurring character within the DC Animated Universe (DCAU) as the Joker's sidekick and love interest, and was adapted into DC Comics' canon seven years later, beginning with the one-shot Batman: Harley Quinn #1 (October 1999).
Everything seems to be going swimmingly until Arthur lets himself into Sophie's apartment after his mother's death, and she barely recognizes him. Viewers then see alternate versions of Sophie's scenes where Arthur is interacting with thin air, clearly indicating that the entire relationship was a fabrication.
Todd Phillips confirmed that Arthur didn't kill Sophie, but her survival was left ambiguous in the film. Arthur spares Sophie due to her kindness, a departure from his violent tendencies towards others.
The ending of Batman: Three Jokers establishes that the Joker's wife did not actually die—rather, she fled to Alaska with the help of Gotham police and Batman because she feared her husband would be an abusive father; the police then told the Joker a story about her dying to protect her.
Believe it or not, this tale saw the Clown Prince of Crime himself become pregnant and give birth to a child. The mother of the child? That was none other than DC's famous magical hero Zatanna, who cast a spell on the Joker after he tried to persuade her to start a family with him.
Jeremiah Valeska is a major antagonist in the television series, Gotham. He is the twin brother of the terrorist cult leader, Jerome Valeska, as well as being the arch-nemesis of Bruce Wayne. Jeremiah is the show's equivalent to the Joker, taking over from Jerome, although both of them never took on the Joker alias.
No, the Joker does not have kids. But, Jokester of Earth-3 had a daughter called Duela Dent who joined the main continuity earth and was oftenn called the joker's daughter.
The Joker becomes both verbally and physically abusive. Rather than blame the Joker for this abuse, Harley convinces herself that Batman is to blame because Batman is constantly getting in the way of her being with her “Puddin.” After her failed attempt to kill Batman and some time in Arkham, Harleen returns.
Penny Fleck was the adoptive mother of Arthur Fleck, a mentally unstable failed comedian who would later call himself the Joker. Much like her son, Penny suffered from an unspecified mental illness.
Superman returned to the prison where the Joker was being interrogated by Batman. Superman then shoved his entire forearm through the laughing Joker's torso and ripped out his heart, killing him.
It is then revealed that the Joker's real name is "Jack Oswald White." Martha then shares that she visited the Flashpoint universe's version of Jack Oswald White, discovering him to be a struggling family man supporting his wife and a child as a janitor at Wayne Casino.
Robin did not become the Joker. The second Robin in the animated series, Tim Drake, was kidnapped by the Joker, tortured, and turned into a sidekick/pet of the Joker called Joker Junior. Batman rescued him, but he was so traumatized that he quit being Robin.
The psychopathology Arthur exhibits is unclear, preventing diagnosis of psychotic disorder or schizophrenia; the unusual combination of symptoms suggests a complex mix of features of certain personality traits, namely psychopathy and narcissism (he meets DSM-5 criteria for narcissistic personality disorder).
The Joker and Harley Quinn have a long and messy history. Ever since Harley's introduction in Batman: The Animated Series, she has spent much of her time as Joker's sidekick, love interest, and most toxically, punching bag.
After this, the DC heroes do what, apparently, nobody has ever thought of doing before, and simply ask Joker if he has a daughter, to which he responds that he doesn't.
