Well, they might be quite amused. They could be proud to see how much the fans love their son Harry. They might also be a bit surprised at some of the creative interpretations that fanfic writers come up with.
They would probably be in for a real rollercoaster of emotions. On one hand, they'd be thrilled to see the love and enthusiasm the fans have for their family's story. They might be particularly fond of the fanfics that show Harry in a positive light, as any parents would. However, they might also be a bit taken aback by some of the more out - there ideas in the fanfic world. For example, some fanfics might have strange pairings or unexpected plot twists that they never could have imagined. But overall, I think they'd be happy that their story has inspired such creativity among the fans.
If James and Lily Potter watched Harry Potter fanfic, they would probably have a range of reactions. They would likely be interested in the different ways the fans have expanded on the wizarding world they knew. Some fanfics might make them laugh, while others could potentially move them. They may also feel a sense of connection to the fans who clearly care so much about their story. It would be a strange experience for them, seeing their lives and their son's adventures through other people's eyes.
They could be shocked at first. But then they might start to enjoy it as they see the creativity of the fans.
It would shock many fans at first. Since in the original series, they are a loving couple. But some fans might be interested in seeing a different take on their relationship. It could also inspire more fanfics exploring different relationship dynamics within the Potter universe.
They would probably be quite amused. It would be strange for them to see different interpretations of their own lives and the world they lived in.
Well, Tony Stark would probably be making snarky comments throughout. He might point out the scientific inaccuracies in the magic system if there are any. Steve Rogers would be a bit confused at first but would try to understand the story. Thor would find it all very strange compared to Asgardian tales.
If the Dursleys watched Harry Potter fanfiction, it would be a complete shock to their system. They have spent so long suppressing Harry's magic and trying to keep their world as normal as possible. Fanfiction often explores different aspects of the wizarding world, some of which might be quite extreme or different from what they think they know. They might initially be very confused, and then probably angry that such things exist. They could also try to stop Harry from having any access to it, thinking it would further fuel his 'unnatural' interest in magic.
Well, it would change a lot. Harry would grow up without his father's influence, which could make him even more of an outcast in the Dursley household. Without James' presence in his life, Harry might not have the same sense of self - worth that he got from knowing his father was a brave Gryffindor. Also, the relationship between Harry and his mother Lily would be very different. Since she made James forget Harry, there must be some underlying reasons that could affect how Harry views his mother.
He might be quite amused. Fanfics often contain different interpretations of the characters and the wizarding world. He could find some creative ideas in them that he never thought of before, like unique magical spells or new backstories for his friends.
One great fanfiction could be 'Lily and James: A Love Beyond'. It delves deep into their relationship before Harry was born. It shows how they met at Hogwarts, their initial dislike which gradually turned into love. The story also includes their adventures as members of the Order of the Phoenix and how they fought against the Dark forces side by side.
It would be very emotional. Harry, who has only known his parents through stories and memories, would now have the chance to actually build a relationship with them. They could be like mentors to him, guiding him in magic in ways he never had before.
It could be a story that focuses on the relationship between James and Lily through their portraits. Maybe it shows how their love story is remembered and revered in the wizarding world even after their death.
