Look at the characters' quirks. For example, draw Snape having a secret love for Muggle disco music as described in a fanfic. Just picture him in his dark robes, but with a disco ball above his head and a slight smile on his face. Another way is to think about the magical elements in a comical way. If there's a fanfiction about the Weasley twins' experiments going wrong, you could draw Fred and George with their hair standing on end and surrounded by a cloud of strange colored smoke.
Look at the small details in the original books. For instance, the portraits on the walls or the magical items that were only briefly mentioned. You could build a story around a particular portrait that has a secret past or a magical item that has powers not yet explored. Another way is to think about the relationships between characters in a different light. What if Draco and Harry had to work together from the very start? It would change the whole dynamic of the story. Also, think about how the wizarding laws could be bent or broken in interesting ways.
A great funny art idea for Harry Potter fanfiction would be to illustrate a story where Dumbledore decides to hold a talent show at Hogwarts. Draw Neville doing a really bad but hilarious magic act that goes completely wrong, like making his toad turn into a giant balloon toad that floats around the Great Hall. You could also create art for a fanfic where the portraits on the walls start gossiping about the students. Depict the Fat Lady and Sir Cadogan chatting and pointing at students as they pass by.
Well, you can start by looking at the existing relationships in the original work and flipping them. In a Star Wars fanfic, instead of Luke being the hero, make it Leia who discovers she has the Force first and becomes the main Jedi. Or take a character from one story and put them in the setting of another. Like a character from Lord of the Rings ending up in the world of Game of Thrones. It's all about mixing and matching elements.
One way is to observe people's funny behaviors and expressions. Another is to play with stereotypes and give them a twist. Also, imagining absurd situations can lead to funny comic ideas.
Look at real - world events and adapt them. For example, if there's a new technology emerging, you can create a story where secret agents are involved in either protecting or stealing it. Say, a new form of energy source that could change the balance of power in the world.
One funny idea could be a story where the Marauders accidentally turn themselves into cats and have to deal with life in Hogwarts as felines. They'd be chasing mice instead of playing pranks on Snape for a while, and it would be hilarious to see them trying to communicate with the other students while being cats.
Mix different genres. For example, combine science fiction with a western setting. This creates a unique concept that stands out. Another way is to take a common object or idea and give it a new purpose or meaning in your story. Say, a simple key that can open different dimensions.
It could be that the person has a very different view of how fictional works can be related. They might see some very minor similarities in the character development arcs or the idea of a hero's journey in both Harry Potter and Naruto and then take it to an extreme by suggesting such a thing. However, when you look closely at the details of each series, it becomes clear that it's a baseless idea. For example, Harry Potter's journey at Hogwarts is about learning magic and fighting dark wizards, while Naruto's is about becoming a ninja and uniting the ninja villages. They are very different in nature.
It could be due to a complete misunderstanding. Maybe they were thinking about ancient or old - fashioned elements and randomly associated papyrus with Harry Potter, thinking it could be some sort of fanfiction concept. But it's a very far - fetched idea.
