What are the possible plotlines in Harry Potter fanfiction with Lily alive?

Yes, there are quite a few. Some focus on an alternate universe where Lily Potter survives. You can find them on popular fanfiction websites like Fanfiction.net or Archive of Our Own. These stories often explore how her survival would change the entire Harry Potter storyline, from Harry's upbringing to the fight against Voldemort.

In some 'Harry married Lily' fanfictions, the plot might revolve around a prophecy that was misinterpreted. Instead of Harry being related to Voldemort in the way it was originally thought, the prophecy could be related to his connection with Lily in a romantic way. This could lead to a whole new set of events where they get to know each other on a deeper level, overcome various obstacles in the wizarding society that would oppose such a relationship, and eventually get married. There could also be elements of family drama, like how James Potter would react in such a scenario, or how Harry's friends would view this relationship.

One possible plotline could be that Lily, now as a girl, has to navigate the wizarding world all over again. She might face different challenges and opportunities than she did before. For example, she could form new friendships or rivalries at Hogwarts.

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.

One interesting plotline is when Lily is given the chance to change the future. In some fanfictions, she has the power to go back in time and make different choices, like whether to marry James or not. Another is when she discovers hidden magic within herself that no one else knew about. This often leads to her having to face new challenges and enemies.

In such a fanfiction, the story could take many turns. Maybe Lily would be able to protect Harry in a more direct way. For example, she could use her magic to shield him from Voldemort's attacks throughout his years at Hogwarts. She might also be involved in the fight against the Death Eaters, using her skills and knowledge.

One possible plotline could be a time - travel scenario. Maybe Ginny somehow travels back in time and meets James and Lily. They could form a bond and Ginny could learn a lot about Harry's early life and family history directly from them.

One possible plotline could be that Harry has done something extremely dangerous or against the wizarding laws in the fanfic world. Lily, as his mother, feels that she needs to discipline him in a more severe way than just a talking - to. So she resorts to spanking as a last - ditch effort to make him understand the gravity of his actions.

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.
