Harry's reaction can vary a great deal. Sometimes, he gets angry because Peter has been keeping such a huge secret from him. After all, they are supposed to be close friends. However, as he realizes the danger that Peter has been facing as Spider - Man, he may come to understand why Peter had to keep it a secret. And eventually, he might offer his help to Peter in his superhero endeavors.
She might be shocked at first. After all, it's not every day you find out your friend is a superhero. But then she could also be really excited and proud of him.
Peter might be embarrassed at first. He's been idolizing Spider - Man and now Tony, a real - life hero - like figure, knows about it. But then he realizes that Tony could be an even greater source of knowledge and support, so he becomes more open about his love for Spider - Man.
In some fanfictions, Mary Jane's reaction can be quite complex. She could be a bit angry at first for being kept in the dark. However, her love for Peter would likely override that anger. She might start to worry more about his safety as Spider - Man, constantly fretting when he goes out to fight crime. She could also become more involved in his superhero life, helping him keep his secret and offering support in ways she didn't before.
Peter could be really nervous at first. He's been keeping this huge secret and now it's out. He might stutter and try to explain himself, saying he was just trying to protect her.
A typical plot development could be that Harry starts to train himself to be able to assist Peter better. He might also face some internal conflict about whether he should tell others or not. In addition, there may be a situation where Peter's enemies target Harry to get to him, and they have to work together to overcome this threat. This type of fanfiction often explores how their friendship evolves under these new circumstances and how they both grow as characters in the face of the challenges that come with Peter's secret identity being revealed to Harry.
In this fanfiction scenario, the order's reaction would be complex. They are a group dedicated to fighting against the dark forces, and Harry is an important figure. When they find out he's been abused, they'd first ensure his safety. They could move him to a secret location, perhaps a safe house that only a few trusted members know about. Then, they'd start looking into the root cause of the abuse. Was it related to the ongoing battle against Voldemort? Were there traitors within their midst? They'd also need to consider how to handle the situation publicly, as Harry is somewhat of a public figure in the wizarding world. Their main goal would be to not only protect Harry but also make sure such abuse doesn't happen again to anyone else in their community.
Snape's reaction could be quite mixed. On one hand, he might be angry at Dumbledore for not doing more if he knew about the abuse. He may also feel a strange sort of empathy towards Harry. After all, Snape himself had a difficult childhood. So, he could start to be a bit more lenient with Harry in his classes and try to subtly offer support.
Well, Bellatrix is a very unpredictable character. In this fanfiction scenario, she could react with glee. Since she's on the side of the Dark Lord, she might think that Harry's abuse has made him more vulnerable. She could also be curious about who would dare to abuse 'the Boy Who Lived'. However, she might also be angry that someone else has been causing harm to Harry when she believes that's her Dark Lord's prerogative.
Well, in some fanfictions, Voldemort might see Harry as a tool to be used against his abusers. He could use this knowledge to manipulate Harry into joining his side, thinking that he can offer protection or revenge against those who have wronged Harry.
Ginny's reaction could also involve a sense of helplessness at first. But then she'd quickly gather herself and use her resources. For instance, she might call on her friends and family for help. She'd be by Harry's side constantly, using her presence to comfort him and also using her knowledge of magic to try and ease his pain.
