Yes, there are quite a few. You can start by looking on platforms like Archive of Our Own. Some fanfictions in this category explore how her survival would change the entire Harry Potter storyline, with her being able to directly influence Harry's upbringing and the fight against Voldemort.
One common theme is family. Since Lily survives, the Potter family dynamic changes completely. Another theme is the alteration of the war against Voldemort. With Lily alive, she could be a major force in the fight.
In some fanfictions, if they survived, they might have changed the whole course of the wizarding war. They could have joined forces with other powerful wizards and witches earlier and potentially prevented Voldemort from gaining as much power as he did in the original story. They might have also influenced the Hogwarts curriculum, emphasizing more on defensive magic against the Dark Arts from an earlier stage.
The relationship between Harry and his parents would be completely different. He would grow up with their love and guidance, rather than feeling like an orphan. There would be a much stronger family bond.
Harry's character development would be significantly different. With his parents alive, he would be exposed to a more stable family environment. His magical education could start earlier and be more comprehensive as he learns from two powerful wizards. This could make him more powerful and less impulsive. Instead of seeking validation from others like he did at Hogwarts in the original story, he would have the unconditional love of his parents, which could shape him into a more well - rounded and less angst - ridden character. For example, he might not have had such a strong urge to prove himself in dangerous situations.
One possible plotline could be that Voldemort's attack on the Potter family fails in a different way. Maybe James uses a powerful, unknown spell that deflects Voldemort's killing curse. As a result, Lily and James go into hiding with Harry. They might then start to form an underground resistance against Voldemort, using their knowledge of the Dark Lord's weaknesses. This could lead to a completely different wizarding war, with the Potters at the forefront, and Harry growing up with his parents by his side, learning magic from them directly.
In the fanfiction, Lily would likely face a great deal of prejudice. The wizarding world would be very suspicious of her because of who her father is. This is different from the original Lily who was respected and loved. So, she would have to work hard to prove herself, which could lead to a more complex and hardened personality compared to the original.
Well, in traditional fanfiction, Lily is often shown as a more straightforward and kind - hearted character. But in manipulative Lily Potter fanfiction, she uses cunning and strategy. For instance, she might trick her enemies into revealing their plans instead of just fighting them directly.
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.
