Well, for Harry, he might grow up with a sense of abandonment. In some fanfictions, this could lead to him having trust issues or a longing to find out about his real parents. For example, he might struggle with his identity, not knowing why his parents gave him away.
Maybe they were forced to. Some fanfictions could depict a situation where an external power, perhaps a more powerful dark wizard or a corrupted magical organization, compels them to give Harry away. This could add a layer of tragedy and helplessness to their story.
One possible reason could be that he realizes his feelings are unrequited. In the fanfiction, perhaps Lily has made it clear she doesn't have the same feelings for James, so he gives up. Another reason might be external factors. For example, there could be some sort of danger or situation that makes James think he needs to step back from Lily for her own good.
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.
One great 'Harry Potter Lily and James Fanfiction' is 'All the Young Dudes'. It delves deep into their time at Hogwarts, their relationship development, and how they became the people we know from the main series. It's well - written with great characterizations.
One possible fanfiction could focus on the moments leading up to their death. It might show James trying to protect Lily and Harry until the very last moment. He could be shown using his wand to fend off Voldemort as long as he could, while Lily was huddled in a corner with baby Harry, praying for a miracle.
Well, it could lead to a very different story. Harry's childhood and upbringing would be completely changed, and the dynamics of the wizarding world might shift.
In some fanfics, James and Lily giving Harry away might be due to a prophecy that requires Harry to be raised away from them for a certain power to develop. So they make the heart - wrenching decision to give him to a family that has some special connection to an ancient magic that can safeguard him.
They could have adventures exploring different realms of heaven. Maybe there are places full of magical creatures they've never seen before. They might be on a quest to find a special kind of magic that can help Harry in some way, even from the afterlife.
Harry would often be a main character in these fanfictions. Since it's about bashing his parents, his reaction and how he copes with the new view of them is a big part of the story. Another could be Sirius Black. He was very close to James, so fanfictions might explore his feelings towards the bashing of his best friend.
