If Batman becomes Joker in fanfiction, Gotham would be in chaos. Batman is the symbol of justice and order, while Joker represents chaos and anarchy. Without Batman to protect the city, criminals would run wild. And as the new 'Joker', Batman might use his intelligence and skills in a very different and dangerous way, perhaps creating more harm than good.
This is a rather complex question. Batman is clearly intelligent. He has been trained in multiple disciplines, from martial arts to forensics. He uses his intellect to solve crimes and protect Gotham. The Joker, though, is a different kind of intelligent. He has an almost insane creativity when it comes to devising his evil plans. He can read people very well and use their weaknesses against them. He doesn't follow the normal rules of society or logic, which in some ways gives him an edge. For example, Batman often has to rely on his moral code and the law, while the Joker has no such constraints. So, it's not really possible to simply say one is more intelligent than the other.
Well, their relationship is extremely complex. The Joker is constantly trying to break Batman's will and sanity. He creates elaborate and cruel schemes. Batman, while detesting the Joker's actions, also has a sort of begrudging respect for his intelligence. He knows that the Joker is a unique and dangerous threat that he has to keep in check. It's like a never - ending battle of good versus evil, where the Joker represents pure chaos and Batman represents order.
At first, Batman would be shocked and a bit confused. But quickly, his detective instincts would kick in. He would view the deaged Joker as a new and unexpected threat. He'd start gathering information about how the deaging occurred, in case it was part of a larger, more sinister plan. Batman would also be very careful not to underestimate the deaged Joker. He might try to isolate the Joker in a secure location to prevent him from causing chaos in Gotham. And he'd be constantly on the lookout for any signs of the Joker's old, devious self emerging from this new, younger form.
In the traditional Batman comics, the relationship between Batman and the Joker is not a love story. It's more of a complex adversarial relationship. The Joker is a villain who constantly tries to cause chaos and harm, and Batman is dedicated to stopping him.
Well, in the real story of Batman and Joker, Batman represents order and justice in Gotham. He uses his wealth, intelligence, and physical skills to combat crime. The Joker emerged as a symbol of anarchy. He doesn't have a clear motive like money or power but just loves to create chaos. Their encounters are always intense, with the Joker constantly devising new and diabolical schemes to challenge Batman.
