What are some interesting plot ideas for Professor Layton crossover fanfiction?

One idea could be that they go on a journey to a mysterious land that's not on any map. In this land, they encounter strange creatures and have to solve puzzles that are based on the unique culture there. Another could be a time - travel plot where they end up in the past and have to figure out how to get back while also helping the people of that era with their wisdom. Maybe a third idea could be that Luke gets kidnapped and Professor Layton has to use all his skills and knowledge to rescue him, facing many challenges along the way.

One idea could be to create a story where Professor Layton has to solve a mystery in an ancient, haunted castle. The castle could be filled with puzzles that are linked to the ghosts' pasts.

One interesting concept could be alternate universes where the characters have different roles or abilities. For example, Layton might be a villain instead of a detective.

If it's a crossover with the Final Fantasy series, characters like Cloud Strife could be included. Cloud's brooding nature and combat skills would contrast with Professor Layton's calm and cerebral approach. Tifa Lockhart could also be part of it, providing her own brand of strength and determination.

One idea could be exploring Snape's childhood before Hogwarts. Maybe he had a secret friendship with a Muggle that no one knew about. This could add depth to his character and explain some of his later actions.

One idea could be that Harry becomes a Defense Against the Dark Arts professor. He could teach students unique spells and techniques he learned from his own adventures. For example, he might introduce a class on how to combat dementors using the Patronus charm in more advanced ways.

He could also face challenges from the school board who are skeptical of his teaching methods because of his unorthodox background.

Another could be a mystery where he has to solve a magical riddle in the school that is linked to his past secrets.

One idea could be that Harry becomes a Defense Against the Dark Arts professor. He could use his real - life experiences to teach students in a more practical way. For example, he might take students on field trips to places where dark magic has occurred and show them how to detect and counter it. Another plot could involve Harry teaching a new subject, like Muggle Studies from a wizard's perspective, sharing his insights on the Muggle world he grew up in. He could also face challenges from some traditionalist professors who don't approve of his unorthodox teaching methods.

One idea could be that Snape discovers Hermione has a rare magical ability that he's secretly been researching. He takes her on as an apprentice of sorts, much to the surprise of everyone.
