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.
One possible fanfiction could be that the Joker, after years of chaos, finally realizes that his true purpose was always to be in Batman's life. In a moment of self - discovery, he approaches Batman not as an enemy but as someone who needs him. Batman, initially skeptical, begins to see that the Joker's madness is a mirror to his own dark side. They start to form an unlikely bond where they complete each other in understanding the fine line between order and chaos.
Well, in 'joker x batman fanfic', the theme of duality is quite prominent. Batman and the Joker are two sides of the same coin. They both exist in the dark world of Gotham, but they have completely different approaches. Also, the theme of redemption sometimes creeps in, especially in fanfics where the Joker might be on the verge of a change or Batman is trying to find a way to save his enemy from himself. And of course, the theme of the cat - and - mouse game, which is always exciting to read about.
One common theme is the battle of wits. Just like in the traditional Batman - Joker relationship, the female Joker in these fanfics tries to outsmart Batman. Another theme is the exploration of madness from a female perspective. It's different from the male Joker's madness and often shows a more calculated and emotional type of insanity.
It's unique because it takes two characters with such complex and well - established personalities like Joker and Batman and flips their relationship on its head. In normal DC Comics, they are arch - enemies. But in yaoi fanfic, their relationship is explored in a whole new light. Writers can play with their power dynamics, their mutual understanding (or lack thereof) in a way that is very different from the original canon. It gives a fresh perspective on these beloved characters and their relationship.
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.
