What are some interesting plot ideas for 'Harry Potter on his own' fanfiction?

One idea could be exploring the deeper bond between Harry and his owl, Hedwig. Maybe a story where Hedwig has some secret magical abilities that help Harry in a unique way during a difficult time at Hogwarts.

In a fanfiction about Harry Potter and his parents, a great plot could be that Harry discovers a hidden diary of his mother. Through reading it, he gets to know her deepest thoughts, her fears, and her hopes. He also learns about the early days of the Order of the Phoenix through her eyes. This discovery could change his perspective on his own life and his place in the wizarding world. He might then be inspired to follow in his parents' footsteps more closely, perhaps by joining an organization that his parents were once part of.

One idea could be exploring a scenario where Harry's mom, Lily, survives the attack from Voldemort. Maybe she has some hidden magic that she uses to fight back at the last moment. This would completely change Harry's life as he would grow up with his mother's love and guidance.

One idea could be Harry exploring a new magical realm on his own and learning unique spells there. Maybe he meets a group of outcast magical creatures who help him on his journey.

A really interesting plot could be that Harry, after the defeat of Voldemort, decides to go undercover in the wizarding underworld to root out any remaining dark wizards. He has to change his appearance and assume a new identity. Along the way, he discovers a conspiracy that is much larger than he expected. He also meets some characters who are on the fence between good and evil and has to decide whether to trust them or not. This would be a very thrilling and different kind of story for Harry.

One idea could be exploring Harry's family vacations. Maybe they go to a magical beach where the kids learn special water - based magic. Another could be a story about Harry teaching his kids about the Marauder's Map and the adventures they have trying to find hidden passages in Hogwarts that even he didn't know about.

One idea could be that without his glasses, Harry has a hard time recognizing his friends at first. This leads to some comical misunderstandings. For example, he mistakes Ron for a first - year student and tries to give him advice. Another plot could be that his lack of glasses makes him more vulnerable in a duel because he can't see the spells coming clearly. It could add an extra layer of danger and suspense to the story.

Well, in some fanfictions, Harry might change his appearance to blend in with a different magical community. Say, he wants to study the magic of the centaurs, so he changes his appearance to look more like them. He could have a horse - like lower body and a more wild - looking upper body. This would not only help him get closer to the centaurs but also give him a whole new perspective on magic. It could also lead to some interesting interactions with other characters who don't recognize him at first.

A great plot for a Potter Manor fanfiction could involve a mystery that surrounds the manor. For instance, strange noises at night lead Harry to uncover a long - forgotten chamber. It could also be about Harry restoring the manor to its former glory, perhaps with the help of Hermione's research on ancient magic used in the construction of such manors.

One interesting plot idea could be exploring what would happen if Harry had a different upbringing, like being raised by the Malfoys. It would completely change his view of the wizarding world and his relationships. Another idea might be a time - travel fanfic where Harry goes back to the Marauders' era and interacts with his parents and their friends. This could lead to him preventing certain tragedies or changing the future in unexpected ways. And then there's the concept of a fanfic where the roles are reversed, and Voldemort is the one trying to protect the wizarding world from a greater evil, with Harry being the main antagonist.
