Joker Jr. is the son of Harley Quinn and the mass-murdering criminal The Joker.
Harley reveals to Black Canary that she has a four-year-old daughter named Lucy who is being raised by her sister. After discovering she was pregnant, Harley left the Joker for almost a year to have their baby instead of abortion.
DC has made it common not to give The Joker any solid backstory or family, but they still managed to accidentally give him a son. Due to DC canceling a comic just a bit too early, they unintentionally left Joker with a son in the form of Lonnie Machin, also known as Anarky.
No stranger to shocking storylines, the Joker became pregnant and gave birth in a new comic from DC Comics. In the latest issue of the Joker: The Man Who Stopped Laughing, the iconic Batman is placed in an unexpected story that sees the Clown Prince of Crime introduce a miniature Joker to the world.
Leaving the newborn baby Lucy with her sister, Harley returned to Gotham only to realize that not only did the Joker not realize she was pregnant, he didn't even care to notice she left at all.
In Injustice: Gods Among Us, Harley Quinn reveals she gave birth to Joker's daughter, but gave her up for adoption rather than subject her to a life with Joker as a father. Similarly, Harley becomes a mother to twin children in the Batman: White Knight universe, though with happier results.
There was no mention of the Joker ever having had a wife and his lifestyle choices (as documented by Batman) certainly didn't support that one. In Batman: The Three Jokers, the "Comedian" is shown having hallucinations or fantasies that Jeannie is alive and their son are living with him.
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.
For example, a DC comic character by the name of Duela Dent went by the moniker "Joker's Daughter" for a bit, alleging the iconic clown was her father. However, that turned out not to be the case. She was then revealed to actually be the daughter of Batman villain Harvey "Two-Face" Dent, at least for a while.
Each twin adapts different characteristics of the DC Comics supervillain the Joker. Jerome is depicted as a chaotic, nihilistic character who spreads chaos in Gotham City until his eventual death, while Jeremiah is a cunning psychopath obsessed with tormenting Bruce Wayne.
Tim Drake as Joker Jr. Joker Jr. (or J.J. for short) is Tim Drake when he was brainwashed and tortured by The Joker in Batman Beyond : Return of The Joker.
Following her introduction to the DC Universe in 1999, Harley Quinn was depicted as the sidekick and lover of the Joker as well as the criminal associate and best friend of fellow supervillain Poison Ivy.
That's right: Batman and Joker are half-brothers, at least according to Penny. The movie never explicitly makes clear whether that's true or not. Arthur, donning a red clown nose, pays a visit to Wayne Manor and performs an impromptu magic show for an enthralled young Bruce Wayne (played by Dante Pereira-Olson).
The Joker does not reciprocate her love and is in fact incapable of romantic emotion as he sees people only as tools to further his own plans. Harley is in denial of this fact and prefers to view him as an antihero until she eventually has to come face-to-face with his complete disregard for her.
Joker Jr. is the son of Harley Quinn and the mass-murdering criminal The Joker.
In Joker, Thomas Wayne (Batman's father) and Penny Fleck (Joker's mother) are key characters. Penny claims that Thomas is actually Arthur's father.
Wayne violently asserts that he is not Arthur's father as soon as Arthur introduces himself, and point-blank tells Arthur that he was adopted and that Penny Fleck had been committed because of her delusional belief there was something between her and Wayne.
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.
As revealed in the comic Batman Beyond 2.0, Bruce Wayne and Barbara Gordon had an affair while Barbara's boyfriend Dick Grayson was away. Barbara fell pregnant.
Warning!
In a world inspired by the beloved DC Animated Universe, Batman once got Batgirl pregnant. Not only is their past relationship scandalous to fans— it's also infuriating to Dick Grayson AKA Nightwing, who was Barbara Gordon's boyfriend at the time.
As he sets off to finally stop Batman once and for all—this time through legal means—he comes to terms with how terribly he treated Harley when he was out of his mind. In issue #2, Jack proposes to Harley, and she accepts.
Duela Dent frequently appears in the Tiny Titans series as the Joker's Daughter. She often antagonizes Robin, who informs her in Tiny Titans #17 that there are no clowns allowed at his birthday party.
Ultimately it was revealed that Duela is the daughter of the The Jokester (Earth-3) and Three-Face (Evelyn Dent) , the Joker's heroic counterpart and archenemy of Owlman (Thomas Wayne, Jr.) This means she is Joker's daughter, just not the mainstream one.
Here's another good one: In this weekend's animated sequel Spider-Man: Across the Spider-Verse, Issa Rae's Spider-Woman, aka Jessica Drew, is the first pregnant superhero to hit the big screen in a major comic book movie.
