What could someone mean by saying 'harry potter is voldemort fanfiction'?

It might be a very strange and creative (but wrong) idea. Maybe they are just randomly combining two very different things without any real logical connection. 'Harry Potter' is about wizards and magic, while'red lantern' comes from a different fictional realm, and this statement is likely just a joke or a very odd thought.

Well, 'Harry Potter saying no fanfiction' might imply that J.K. Rowling or the rights holders of the Harry Potter series don't want fan - made stories. Fanfiction often takes the original characters and settings and creates new scenarios. They might be worried about it diluting the brand or going against their vision for the story. For example, some fanfictions might change the personalities of the characters in ways that the original creators don't like.

It could just be a joke. They might be imagining a really wacky crossover where Harry Potter is a fan of Batman in some sort of alternate universe. Maybe they think it would be funny to combine the two very different worlds.

It could mean that within the context of the Harry Potter world, there is an idea or statement where Harry Potter, as a character, is opposed to fanfiction. Maybe it implies that the official or 'true' story as per the original works doesn't want to be overshadowed or misrepresented by fan - created stories.

In such a fanfiction, Harry might be tortured for information about the Order of the Phoenix. Voldemort could try to turn Harry to the dark side, using threats against his friends.

In some Harry Potter fanfictions, Voldemort's pet could be a large and menacing snake, like Nagini. Since snakes are often associated with Slytherin and Voldemort was a descendant of Slytherin, it makes sense for his pet to be a snake. It could also be some sort of dark magical creature, perhaps a basilisk under his control. Another possibility is a magical raven or crow, which could be used as spies for him, flying around Hogwarts and other places to gather information.

In such a fanfiction, Harry might go to Voldemort to try and reason with him. Maybe he believes there's a chance to end the war without more bloodshed. He could offer Voldemort a way out, like exile instead of death.

One possibility could be that Voldemort has a sudden change of heart. Maybe he realizes that Harry is the only one who can truly understand his loneliness and power. So instead of killing Harry, he decides to save him from a dangerous situation, like a powerful dark magic that even Voldemort fears could destroy the wizarding world if not controlled, and in the process, they form an unlikely alliance.

Maybe a plot could involve a powerful spell that binds their fates together and they have to learn to live with each other. Eventually, they might start to understand each other's motives and fall in love.

Perhaps Harry joins Voldemort out of a sense of hopelessness. After seeing so much destruction in the wizarding world, he might think that joining Voldemort is the only way to end the war quickly. However, he soon realizes that Voldemort's methods are too extreme and tries to find a way to turn things around from within the dark side.
