One of the mysteries in director Todd Phillips' Joker is whether Arthur Fleck really is the son of Thomas Wayne as his mother Penny Fleck claimed. Both Wayne himself and Arthur Pennyworth said it was untrue and that Penny was delusional, hence her eventual stay in Arkham Asylum.
On antimatter Earth, Owlman was now Thomas Wayne Jr., the older brother of that reality's Bruce Wayne. In most mainstream DC universes, Batman's genesis occurred when young Bruce Wayne was witness to the murder of his parents, and was inspired to devote his life to fighting crime.

Martha reveals that she forced Psycho-Pirate, a villain with extensive knowledge of the entire DC Universe, to tell her the name of the Joker in the main DC Universe. It is then revealed that the Joker's real name is “Jack Oswald White.”
Why do Batman and Joker hate each other? They don't hate one another. Batman hates the things the Joker does, and the Joker hates that Batman won't allow himself to join in the fun. If Batman hated the Joker, he would have caved under the pressure to deal with him permanently.
Penelope "Penny" Fleck is the deuteragonist villain of the 2019 psychological thriller film Joker, the first installment of the DC Black film series. She is the adoptive mother of Arthur Fleck, a mentally unstable failed comedian whose lack of success and respect triggers his transformation into the Joker.

High Physical Conditioning: The Joker is not exceptionally strong or fast, but despite his appearance he has immense stamina and pain tolerance. The Joker has cheated death numerous times, even in seemingly inescapable and lethal situations.
Arguably the Joker's greatest weakness is his ego, however. He turns to crime to get the attention he desperately craves from Batman.
Joker IQ is estimated to be around 160 IQ, which is not really surprising. Meanwhile Batman's IQ is around 192. The Joker is, in fact, more twisted than intelligent. Joker has chosen to use his intelligence in a different way than his archenemy Batman, who uses it to strengthen his arsenal and improve Gotham.
