Perhaps a plot where the characters in Harry Potter find a way to travel across different universes within the wizarding world. They could encounter alternate versions of themselves or discover new magical creatures and spells that are unique to those other universes. This would add a whole new level of adventure and mystery to the story.
One interesting plot idea could be a crossover where the 'across the universe' concept brings different magical universes from the Harry Potter world together. For example, the wizarding schools from different countries might interact in unexpected ways.
Another idea is a fanfiction that focuses on the Marauders' time at Hogwarts. We could see more of their pranks, their relationships, and how they dealt with the growing threat of Voldemort. For example, exploring how Sirius and Remus' friendship developed during those years in greater detail. It would also be cool to see more of James Potter's character before he became Harry's father.
One interesting plot could be if Harry was sorted into Slytherin instead of Gryffindor. It would completely change his relationships and how he's perceived. He might have to deal with the prejudices of his own house while also trying to figure out his role in the fight against Voldemort.
One idea could be a universe where Voldemort won the Battle of Hogwarts. The wizarding world would be in complete chaos and oppression. Harry could be in hiding, trying to find a way to fight back against Voldemort's regime. Another plot could be a world where the Sorting Hat makes different decisions for all the characters. For example, Hermione could be in Slytherin, which would completely change her relationships and the way she approaches magic. Or a parallel universe where magic is known to muggles and they co - exist in a very different way than in the original series.
One idea could be a crossover with the Lord of the Rings universe. Harry and his friends could find themselves in Middle - earth, having to deal with Sauron's forces while also using their magic. Another could be a crossover with the Star Wars galaxy, where wizards and witches interact with Jedi and Sith. Maybe they could learn from each other's use of the Force and magic.
One plot idea could be that Lily's presence changes Harry's upbringing completely. Instead of growing up with the Dursleys, he has a loving home with his mother. Maybe she starts teaching him magic early on, which gives him an edge when he enters Hogwarts. This could also lead to a different dynamic with his friends, as he might be more confident and skilled from the start.
A great plot for 'across the stars' fanfiction could be a survival story. Maybe the characters are stranded on an uncharted planet and have to use their skills and knowledge to survive. They could face dangerous creatures, harsh weather, and limited resources. Or, you could write a story about a forbidden love between characters from different factions in the 'across the stars' world. This would involve a lot of drama as they try to keep their relationship a secret while also dealing with the expectations and rules of their respective groups. Also, a mystery - solving plot where the characters have to figure out who is behind a series of strange events in their universe would be exciting.
There are 'across the universe fanfiction' stories that focus on the political intrigue among different alien races. For example, a story where a young hero tries to stop a war between powerful galactic empires. They might have to form alliances and make difficult decisions. Also, some fanfictions might explore the origin of certain alien cultures in this universe.
One idea could be a love story between a modern - day person and a historical figure. For example, a young woman from 2024 who accidentally travels back to the Victorian era and falls in love with a nobleman. Another could be two souls who are fated to meet across different time periods in history, like in ancient Rome and then again in the 1960s.
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.
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.
