He might be quite shocked at first. After all, Wolfstar involves his dad's best friend Sirius and his other dad figure Lupin. It's a rather strange concept for him to think about them in a romantic way as he knew them in a different context.
Harry would likely be initially taken aback. Since he has such deep personal relationships with Sirius and Lupin, seeing them paired romantically in fanfiction could make him feel a bit uncomfortable. However, he's a very open - minded person. So, after the initial shock, he may come to understand that it's a form of creative expression by fans who are simply exploring different aspects of the characters. He might not fully embrace it, but he would respect the creativity behind it.
Well, Harry could be a bit confused. He might start to re - evaluate his understanding of their relationship. But then he would probably realize it's just fan - made fiction and not the real history of his loved ones. He might even find it a bit amusing in a way, thinking about how creative fans can be.
In some fanfictions, Snape might be secretly sympathetic. He may see the scars as a reminder of all Harry has been through, which could soften his usually harsh attitude towards Harry, at least for a moment.
Charlie may initially be confused. Fanfiction isn't something he might be very familiar with. But once he understands what it is about Harry and Ginny, he might just shrug it off. He's got his own life with dragons and such, so he might not really care all that much as long as it doesn't cause any real - world problems for his sister and Harry. However, if it spreads some false or unflattering rumors in the wizarding community, he might get a bit annoyed.
He would probably be very displeased. Snape has always been strict and traditional, and fanfiction about the DA, which was an unauthorized student group in his eyes, would seem like a frivolous and inappropriate thing to him.
Well, Percy has seen a lot in his adventures. At first, he might be a bit taken aback because fanfiction is a whole new world compared to his real experiences. However, as he realizes that it's just fans exploring different scenarios with the characters, he could become rather indifferent. He might even start to see the value in it, as it shows how much the fans care about the overall story and its characters. He might think it's a little strange that people are so interested in writing about Nico and Will's relationship, but he'd respect the creativity of the fans.
Cedric would be deeply troubled. In the wizarding world, they have their own code of honor and respect. Finding out about Harry's abused fanfiction would go against everything Cedric stands for. He might start to question the morality of the Muggle world that allows such things to be written. He would also feel a sense of sadness for Harry, knowing that someone out there has created a story that portrays him in such a negative and harmful light. Cedric might even consider taking some sort of action, like talking to Harry about it or trying to get the fanfiction removed if he could, though that would be a complex matter given the nature of fanfiction and the different worlds they live in.
Harry would probably be quite startled at first. The idea of Sirius and Remus in a relationship as depicted in the fanfiction photos is not something he's ever considered. But as he looks at the photos more, he could become more understanding. He's used to different magical concepts, and this could be just another one for him to wrap his head around. He might even feel a sense of pride that his father's friends were so interesting that fans created such elaborate stories and photos about them.
Naruto might be super excited. He loves making new friends, and a toddler would be like a new little friend to him. He'd probably start showing off his ninja moves to make the toddler laugh.
Harry's reaction would be complex. He has so many emotions tied up with Snape already - dislike, confusion, and a bit of grudging respect in some ways. Discovering he's his father would bring all those emotions to the surface and more. He might go through a period of denial, not wanting to believe it at first. Then, as the truth sank in, he'd have to come to terms with a new family member. He might also feel a sense of betrayal from those who knew or suspected but didn't tell him. And he'd have to figure out how to fit this new relationship into his life, especially considering his role in the wizarding world and his ongoing battles.
Often, Harry is a bit skeptical at first when he finds out about his inheritance in fanfiction. He has grown up thinking he was an ordinary orphan, so this new information seems almost too good to be true. But as he starts to understand more about what it means, he becomes more accepting and starts to see the possibilities it brings. For example, if he inherits a powerful magical ability, he might be hesitant at first but then get excited about how it can help him protect his friends.
Naruto would feel a sense of responsibility. He might think that it's his duty to do something about it. He could start by examining the chains to see if there is any way to break them. He would also be on high alert because he doesn't know if this is some sort of trap. He would be thinking about all the possible consequences of his actions and how it could affect the world around him.
