James Potter often makes an appearance. Since he was Lily's husband, his relationship with both Harry and Lily is explored in different ways. For example, in some fanfictions, Harry gets to see a side of his father through Lily's memories that he didn't know before.
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.
One common plotline is time - travel. For example, Harry might go back in time and interact with Lily Potter in a way that changes the course of events. Another could be an alternate universe where Lily survives and she and Harry have a different kind of relationship, perhaps more of a mentoring one.
One common theme is the exploration of family ties. Since Lily is Harry's mother, stories might focus on how Harry could have interacted with her if she had survived. Another theme could be the transfer of magical knowledge. Lily was a powerful witch, and fanfictions may show her passing on her knowledge to Harry.
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.
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 popular type of Lily Potter fanfiction might focus on her time at Hogwarts before she met James. It could explore her friendships, her studies, and how she dealt with the challenges of being a young witch in a magical school. For example, a story could show her in her Potions class, working hard to master difficult spells and potions, and forming a study group with her closest friends.
There's also 'Lily's Return'. In this fanfic, Lily comes back to the wizarding world through some magical means. It's interesting as it explores how Harry reacts to having his mother back. The author does a good job of depicting the emotions of both characters, especially Harry's mix of disbelief, joy, and confusion.
One main theme is family. Since their relationship in the original story was that of mother - son, fanfictions often explore how that bond can be re - defined or strengthened in different ways. For example, in some fics, they might support each other through difficult times like in 'The Unlikely Bond' where Lily's presence gives Harry the strength to face his toughest challenges.
