A villain like Shigaraki would likely be interested in the power levels in the MCU fanfiction. He's always looking for ways to increase his own power, and seeing the various powerful artifacts and abilities in the MCU might give him some ideas. He could think about how he could use similar things in his own plans to take over the MHA world.
One way is to start fanfiction contests that have specific themes related to the positive aspects of 'The Owl House', such as the exploration of the different magical realms or the development of the characters' personalities. By highlighting these areas, fans are more likely to create positive fanfiction rather than sexual ones. Also, fan communities can promote and share only the positive fanfictions they find, creating a positive cycle.
It's mainly about the adventures in a magical world. There are unique characters, like witches and demons. It shows their relationships and the challenges they face in this strange place.
Sure does! The Owl House comics expand on the world and characters of the show. They provide more depth and entertainment for fans. Some comics might even fill in gaps or offer alternate scenarios.
Some MHA characters might be flattered. For example, Midoriya would probably be really excited and take it as a sign of how much he's inspired people. He might even look for positive lessons in the fanfiction to improve himself.
If the MHA characters were to react to a Mastermind fanfiction, some would be more accepting than others. Characters like Ochaco might find it really exciting. She's a fan of the heroes herself, so seeing different takes in fanfiction would be like getting a new perspective on the MHA world. However, characters like Shoto, who are more reserved, might be a bit hesitant. He might need some time to process what he's reading. But overall, it would be a very interesting scenario as it would show how the characters view different interpretations of their world.
