Well, perhaps in the fan fiction, Harry Briggs and Tatum are part of a time - traveling team. They travel to different eras and have to blend in while also trying to complete a mission that could save their own time. Or, they could be in a world where music has special powers and they are on a quest to find the most powerful musical note to defeat an evil force that is trying to silence all music.
One idea could be that Harry Briggs and Tatum go on an adventure through a magical forest. They discover hidden creatures and have to work together to solve a mystery that the forest holds. Another could be a story where they are in a school setting and form an unlikely friendship that helps them both overcome their personal challenges.
Obviously, Harry Briggs and Tatum are the main characters. Harry might be portrayed as a brave and adventurous type, always ready to take on challenges. Tatum could be the more level - headed one, providing balance to Harry's impulsiveness.
One idea could be exploring Dumbledore's early years as a student. Maybe he had a secret friendship or rivalry that shaped his views. Another could be a story where Dumbledore has to face a powerful dark wizard before Voldemort, and how that experience influenced his later actions against the Dark Lord. A third idea is to write about Dumbledore's travels and the magical creatures and cultures he encountered during them, which might have given him insights for Hogwarts' teachings.
One idea could be exploring the backstories of minor characters. For example, the life of Neville's parents before they were tortured by Bellatrix. Another could be a story set in a different wizarding school around the world and how it interacts with Hogwarts. Maybe a story about a group of students from Beauxbatons and their adventures during the Triwizard Tournament that we didn't see in the original books.
One idea could be exploring how Harry copes with the physical and emotional changes. For example, he might struggle with the new limitations his pregnant body has while still trying to be involved in his usual activities like magic training. Another plot could be about the reactions of his friends. Hermione might be super supportive and researching all she can about wizarding pregnancies, while Ron could be initially shocked but then grow to be very protective.
One idea could be that a character from the Harry Potter world leaps into the body of a Quantum Leap character and has to navigate their life while also trying to find a way back. For example, Harry could leap into Sam Beckett's body during one of his more dangerous leaps and use his magic skills to help Sam complete the mission.
One interesting plot idea could be exploring the alternate timelines more deeply. For example, what if the characters got stuck in a timeline where Voldemort had won? Another could be delving into the relationships between the next generation of characters in ways not fully explored in the original play. Maybe a story where Albus and Scorpius have to face a new dark wizard threat together, relying on their unique bond.
A really cool plot could be that they are both involved in a charity event. Harry is there to perform and Ashley is helping with the organization. They get paired up for a part of the event where they have to interact closely with the fans. During this time, they discover how kind and passionate the other is about helping others. This mutual admiration turns into a deeper relationship as they continue to support the charity together.
Perhaps a fan fic where a student travels back to the time of the founders of Hogwarts. They could witness the creation of the houses and the laying of the school's foundation, and even interact with the founders, which would be really cool.
Well, you could write a fan fiction where Jupiter discovers she has latent powers that no one knew about, not even Caine. She starts to develop these powers gradually and Caine has to help her control them while they are on the run from the bad guys. This could lead to some really interesting character development and action - packed scenes as they figure out what's going on with her new abilities.
One idea could be a story where the Mandalorian has to team up with an old enemy to fight a new, greater threat. Maybe a powerful Sith Lord emerges and they have to put aside their differences.
