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.
The plot could take a really dark turn. Harry, as the Joker, might start toying with his enemies in a cruel way. He could set up elaborate traps for Death Eaters, not to defeat them in a traditional sense, but to make them suffer. He might also start spreading false rumors and misinformation throughout the wizarding world, causing paranoia and distrust. His actions would force the wizarding community to reevaluate their security measures and the very nature of magic itself. And his journey from a hero to this chaotic figure would be a long and torturous one for those who knew him before.
If Harry Potter becomes the Joker in fanfiction, the plot might develop in a way that the wizarding world has to unite against him. However, it would be a complex situation because some might still remember the old Harry and be reluctant to fight him. Meanwhile, Harry could be recruiting other outcasts or those with a grudge against the system to join his side of chaos. He could also use his skills to break into places like Gringotts and steal valuable magical items, just for the fun of it, not for any noble cause like before.
The plot could develop in a very dark way. Harry might start hunting down the Order of the Phoenix members. He would be using his knowledge of the good side to help the Death Eaters. For example, he could lead them to the secret passages in Hogwarts.
The story could start with Harry noticing some strange and menacing behavior around him that he can't quite explain. As he digs deeper, he discovers it's the Joker. Harry might then try to enlist the help of his friends like Ron and Hermione. They could come up with plans to trap the Joker or at least find out what he wants. Meanwhile, the Joker would be constantly one step ahead, leaving behind his signature chaotic clues.
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.
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.
The story could develop in many ways. One way is that Percy would start to corrupt the demigod world. He might spread his new - found chaos among the other demigods, turning some of them to his side. Another way is that he could create his own little 'kingdom' of chaos, ruling over a group of misfits. This would put him in direct opposition to the Olympians, who would see him as a threat to their order.
The development of the story when Harry becomes a Jedi Master in fanfiction would be quite complex. Harry's new Jedi abilities would disrupt the power dynamics in the wizarding world. For example, his ability to sense things with the Force could give him an advantage in finding hidden Horcruxes. His Jedi training might also lead him to question some of the long - held beliefs in the wizarding world. Moreover, his interactions with other characters would change. Some might be in awe of his new powers, while others, like the pure - blood supremacists, might see him as an even greater threat. His adventures would no longer be limited to the wizarding world but could extend to different planets in the Star Wars universe, where he'd face challenges and make allies based on his dual identity.
In this fanfiction, perhaps Harry's identity as the Joker's son makes him an outcast in the wizarding world. The story could revolve around him trying to prove that he's not just a product of his 'father's' evil. He could use his Joker - like cunning and unpredictability to outwit his enemies in Hogwarts, who might be prejudiced against him due to his strange heritage.
Well, it could be about Harry having the chaotic and unpredictable nature of the Joker as his 'father' in this fanfic world. Maybe he uses some of the Joker's unorthodox tactics in the wizarding world, causing a stir among the witches and wizards. He might have a very different approach to dealing with Voldemort compared to the original story.
One idea could be that The Joker somehow finds his way into the wizarding world. Maybe he uses his chaos - creating skills to disrupt the Quidditch World Cup. He could start by magically disguising the bludgers to attack players randomly, causing mayhem on the pitch. This would draw the attention of Harry Potter and his friends, who would then try to figure out who this strange, non - magical yet extremely dangerous character is and how to stop him from causing more trouble in their world.
Well, it could be about the Joker somehow getting transformed into a baby. Maybe he retains some of his villainous traits even as a baby, causing chaos in a comical way. For example, he might still have that evil laugh and try to play pranks on the other characters in the story.
