Some characters may be excited. They might enjoy seeing their world expanded in new ways. For example, a side character could be happy to see themselves getting more spotlight in the fanfiction.
I don't think it's common. Most fanfiction is centered around established stories, like popular movies, books, or TV shows. While the idea of descendants and their future is an interesting concept, it's not something that a large number of people typically engage with in the fanfiction world. There are so many other more mainstream topics in fanfiction that draw more attention.
They could be shocked. If the fanfic takes a really unexpected turn, like making a villain into a hero suddenly, the characters might be taken aback. It's like seeing a completely different version of their world.
A fanfiction centered around Mal and Ben's pregnancy would be full of emotions. First, there would be the joy of the new life coming. However, they would face challenges. For example, Mal's past as a villain might make her worry about passing on bad traits. Ben, on the other hand, would have to deal with the political side of things. How would the people of Auradon view their future queen being pregnant? It could lead to some interesting plot twists, like some characters trying to use the situation for their own gain while Mal and Ben focus on their growing family.
If parents come across disturbing content in Descendants fanfiction, they should immediately stop watching it. They can also report the content to the platform where they found it if possible.
He might be really surprised. Naruto is used to his own world and the fanfiction could show things he never imagined. For example, if the fanfiction has his kids achieving great things in new ways, he'd be proud yet a bit shocked at how creative fans can be.
He might be shocked at how the village has developed. In some fanfictions, the village could have advanced technology. Naruto, being from a more traditional ninja world, would likely be both amazed and a bit confused at first.
He might be shocked at first. In fanfiction, the future could be full of unexpected changes. He could be excited to see how his friends and the village have developed. Maybe he'd be a bit sad if things didn't turn out as he hoped for his loved ones.
Well, they may react with a bit of nervousness too. The future in the fanfic could bring new challenges like changes in the music industry trends. For example, new technologies might require them to adapt their performance and promotion methods. They might worry about whether they can keep up with the fast - paced changes while still staying true to their art. But at the same time, they would also be determined to face these challenges head - on because they have always been a group that thrives on growth and evolution.
