Who are the popular characters in Harry Potter x Lily Potter fanfiction aside from Harry and Lily?

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.

Well, obviously Harry and Lily themselves are very interesting. Harry because we get to see a different side of him when interacting with his mother. Lily is interesting as we can learn more about her personality and her life before Harry was born. Then there's James Potter. In fanfiction, we might see more of his relationship with Lily and how he influenced Harry even from the afterlife. And Snape, his complex relationship with Lily can be further explored in the context of these fanfictions.

One common theme is redemption. Since Lily died in the original story, in fanfiction she often gets a chance at redemption, like making up for lost time with Harry. Another theme is the power of love. Their relationship is a strong display of love's power, which can overcome many difficulties.

In Lily Potter Returns fanfiction, Sirius Black can be a character paired with her. They were friends in the past, and now that she's back, their friendship could be deepened or turned into something more complex. Additionally, Remus Lupin might be included in stories, as he was part of their group, and his interactions with Lily can add an interesting dynamic.

One popular fanfiction could be 'Lily's Legacy'. It explores Lily Potter's life before her death and how her magic might have influenced Harry in ways not shown in the original books. Another is 'The Untold Bond between Lily and Harry' which delves into a deeper emotional connection between them, with some creative plotlines that give a fresh perspective on their relationship.

Petunia could be an important character. She might be grudgingly attending the wedding, still having mixed feelings about Lily's magical world. Her presence could add some tension as she struggles to fit in. And then there's Dumbledore. He could make an appearance and give some wise words of advice to the couple, perhaps about the future challenges they might face together.

Harry Potter could be a main character. If he's the father, he would play a significant role in the girl's life, teaching her about magic and protecting her. He could also pass on his own experiences and values.

There are fanfictions that rewrite the story from Lily's point of view. In these, we get to see all the major events in the Harry Potter series through her eyes. It's really interesting as we can understand her thoughts and feelings during key moments like when she was facing Voldemort. This gives a fresh look at the familiar story.

One possible fanfiction could be about Lily Potter's ghost guiding Harry in a more direct way than in the original books. Maybe she appears to him during his toughest times at Hogwarts, like when he's facing Voldemort in the Chamber of Secrets, and gives him some special advice or magic that only a mother could pass on.

A possible fanfiction could involve Lily Luna Potter and her time - traveling adventures. She accidentally stumbles upon a time - turning device and gets sent back to the time of the first Wizarding War. There, she has to be careful not to disrupt the timeline while also trying to learn from the events of that time to prevent a similar future catastrophe.
