If Harry Potter becomes the Joker in fanfiction, he would probably start to question all the values he once held. The Joker is all about subverting order, so Harry might begin to undermine the Ministry of Magic and other institutions. He could use his knowledge of magic to play cruel pranks on people, not the innocent kind of pranks he used to do. His Gryffindor courage could be twisted into a reckless disregard for the safety of others.
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.
I'm not sure if there is a specific instance where a 'Joker' would be directly involved in raising Harry Potter fanfiction. Usually, fanfiction is created and promoted by fans themselves within the fan community, not by a character like the Joker.
Well, if we're talking about the Joker from the Batman universe, there's no canonical information indicating he has any knowledge of Harry Potter fanfiction. He's more preoccupied with chaos in Gotham. But in some wild crossovers in fan - created works, he might be depicted as knowing it, just for the fun of mashing up different universes.
The Joker as a professor in Harry Potter fanfiction? That's a wild idea. He could be the professor of Dark Arts in a very different way. Instead of the traditional Dark Arts that the wizarding world knows, he would introduce his own form of 'dark art' which is more about psychological torture and mind games. His classes would be full of his maniacal laughter and unexpected challenges. Students would have to constantly be on their toes, not knowing what he'll do next. He might even use his students in his elaborate schemes against the other professors or the Ministry of Magic.
One possible plotline could be that Harry, after some dark magic influence or a strange accident, starts to show Joker - like behavior at Hogwarts. He might play cruel pranks on his classmates and teachers, using his magic in unexpected and unethical ways.
One common theme is the clash of two different worlds. The orderly and magical world of Harry Potter with its own set of rules and the chaotic, lawless world that the Joker represents. Another theme could be the corruption of innocence. The Joker might try to influence the young wizards and witches at Hogwarts, corrupting their pure intentions.
It would be really strange. Harry Potter is from a magical world of wizards and witches, while the Joker is a chaotic and often dark character from the Batman universe. Maybe in this fanfiction, Harry could have the Joker's unpredictable nature and use his magic in really devious ways.
Yes, there might be some out there. Fanfiction is a vast world where people combine different fictional universes in creative ways. You can try searching on popular fanfiction websites like Archive of Our Own or FanFiction.net. However, the quality and content can vary greatly.
One idea could be that Harry discovers a hidden centaur community in the Forbidden Forest. He's initially scared but soon realizes they have a deep connection to magic that Hogwarts has not taught. He starts learning from them, about their archery skills and how they communicate with nature.
