The main characters are James and Lily Potter. They are the ones coming back. But other characters like Sirius Black could also play important roles. Since he was James' best friend, he would be very involved in their return. And then there's Dumbledore. His wisdom would be needed to deal with the implications of James and Lily's return. And of course, Harry, who would have a whole new relationship with his parents.
Obviously, James and Lily Potter are the main characters as the title implies. Their return is the central event. Harry Potter is also a key character as their return would greatly impact his life.
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.
Harry would likely be overjoyed at first. After all, he never really got to know his parents. Their return could give him a sense of family and belonging that he's always craved. It could also help him deal with some of his past traumas, having his parents there to support him.
One of the main characters often featured is probably Sirius Black. Since he was so closely associated with James, he can be a key figure in these fanfictions, either trying to defend James' reputation or being forced to face the new, negative view of his friend. Another character could be Severus Snape. Given his complex relationship with both James and Lily, he can play a major role in these stories, perhaps finally getting the 'upper hand' over James in some bashed - version scenarios.
One possible plotline could be that James and Lily return and have to deal with the changed wizarding world. They might be shocked at how much Voldemort's actions have affected society even after his defeat. Another could be that they return to help Harry face new threats that are emerging from the shadows of the old war.
The main characters are obviously James Albus and Lily Potter. They are likely to be the central focus of the fanfiction, with their adventures and experiences at Hogwarts being the main storyline.
Harry's view of the world might change completely. He has seen so much darkness and death. With his parents' return, he could start to see the world in a more hopeful light. He may be more willing to forgive those who have wronged him in the past, like Snape. Their return would be a catalyst for a huge shift in his personality, making him more balanced and less haunted by his past traumas.
One possible plotline could be that Lily and James return during the time of Harry's battle with Voldemort. Their return could give Harry new strength and hope. They might use their old magical knowledge and skills to help in the fight. Maybe they could also reunite with their old friends like Sirius and Remus, and together they form a powerful force against the Dark Lord.
The main characters are James Potter and Lily Evans, of course. James is a popular and sometimes mischievous wizard at Hogwarts. He's known for his talent in Quidditch and his group of friends. Lily, on the other hand, is a bright and intelligent witch. She's kind - hearted but also has a strong will, which makes her very interesting.
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 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.
