How could the story develop if Harry Potter is stalked by the Joker in fanfiction?

In such a fanfiction, it would be a very strange and chaotic scenario. Harry Potter comes from a world of magic and the Joker from a world of dark, madcap crime. If the Joker were to stalk Harry, Harry would likely be extremely confused at first. He might try to use magic to fend off the Joker, but the Joker's unpredictability would make it difficult. It could lead to a lot of psychological warfare as Harry tries to figure out the Joker's motives and protect himself and his friends.

The plot could start with a dark spell or some kind of mind - altering event that turns Harry into the Joker - like figure. Then, he might start attacking the very people he once protected, like his classmates at Hogwarts. This would create a lot of chaos within the school walls. The teachers would be at a loss on how to deal with him, as his magic combined with the Joker's unpredictable nature would be a very difficult combination to handle.

Well, it could happen in a world where magic and the chaos of Gotham collide. Maybe Harry uses his magic to get into the Joker's mind and find the good that's left in him. He could use a spell like Legilimency to understand the Joker's past traumas and then use healing magic to start the process of redemption.

Well, in a fanfiction world, anything can be possible. Maybe Harry Potter uses his magic skills like the Killing Curse. But it's really a strange crossover. The Joker is from a completely different universe with no magic, and Harry Potter is from a world full of magic. It would be a very unique and perhaps disturbing story to see how Harry Potter overcomes the Joker's chaos and madness with his magic and finally kills him.

The story could develop in a very dark way. Batman, as Joker, might start to create his own brand of 'jokes' which are actually cruel and harmful pranks on the citizens of Gotham. His rogues' gallery might be both confused and excited by this change, not sure whether to team up with him or oppose him.

Well, in this fanfiction scenario, the very essence of Harry Potter's character would be different. His upbringing by the Joker would mean that his understanding of good and evil is blurred. He might see the wizarding world as a playground for his own brand of chaos. His friends from the original story might become his enemies or he might not have any friends at all. The fight against Voldemort would no longer be a central theme. Instead, Harry could be creating his own brand of mayhem. His magical powers could be used in ways that are not in line with the traditional use of magic in the wizarding world. It would be a completely different kind of story, one that is full of dark humor, chaos, and a lack of the moral foundation that the original Harry Potter series is built upon.

His magic might develop in a more unorthodox way. The Joker's erratic behavior could lead Harry to use magic in unpredictable situations, which might make his spells more spontaneous but also less controlled.

The story could start with Harry somehow being transported to the Star Wars universe. He'd quickly realize the power of the Force and seek out the Jedi for training. His natural magical talent would make him a fast learner. As he progresses, he could use his Hogwarts spells in creative ways against the Sith. His Gryffindor courage would be an asset in Jedi battles.

It could develop with Harry having to choose between the two worlds he now belongs to. He might start using Lucifer's power to solve problems in the wizarding world, but that would lead to unforeseen consequences. For instance, if he uses dark magic to defeat Voldemort, the wizarding world might not accept him as a hero. And as he gets more involved with Lucifer, he could lose touch with his friends and the values he held dear at Hogwarts.

The story could develop with Harry having to hide his new form from most of the wizarding world. Only a few close friends might know. He'd have to learn to control his new lich powers, which could be very dangerous if not properly harnessed.
