What are some interesting plot ideas for a Harry Potter reunion fanfiction?

One idea could be that Harry returns from a long and dangerous mission. Ginny has been worried sick. When they reunite, there's an immediate rush of emotions. They hug tightly and Ginny scolds Harry a bit for making her worry, but it's all out of love. Another could be they reunite at Hogwarts during an anniversary event. They see each other across the Great Hall and slowly make their way towards one another, with memories of their school days flooding back.

Another interesting concept is a reunion that is centered around a magical tournament. The characters are invited back to Hogwarts to participate or watch. Old rivalries might be reignited in a friendly way, and new friendships could form among the younger generations as they look up to the famous Harry Potter and his friends.

One plot idea could be that Harry has been away on a long and dangerous mission. When he returns, Ginny is initially angry at his long absence but then realizes how much she still loves him. They then go on a journey to revisit the places that hold special memories for them, like the Hogwarts grounds, and rekindle their relationship.

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.

A great plot could involve a Pokemon reunion where the Pokemon themselves organize the event without the trainers knowing. They set up all kinds of challenges and games for each other, and the trainers are left wondering what their Pokemon are up to. It could also be about a group of retired trainers who reunite and share stories of their adventures, and their Pokemon also have a sort of 'reunion' among themselves, showing off new skills they've learned over the years.

One idea could be that the original Glee club members reunite to put on a charity show. They face old rivalries resurfacing but also rediscover their love for performing together. Maybe some of them have become big stars and some are still struggling, and they learn from each other's experiences.

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 traveler could be from a different magical realm entirely and come to the Harry Potter universe. They bring with them unique magical abilities that both fascinate and frighten the wizards in the Harry Potter world. This could lead to a series of adventures where they either share their knowledge or are hunted down by those who fear the new magic they possess.

One idea could be that Hecate, being the goddess of magic, takes Harry Potter under her wing secretly to teach him ancient and powerful magic that Dumbledore doesn't know. This could lead to Harry having new abilities to fight Voldemort.

A possible plot in Harry Potter Planeswalker fanfiction is that a Planeswalker accidentally brings a dangerous creature from another plane into the Hogwarts grounds. This causes chaos as the teachers and students have to figure out how to deal with it. It could also be that a Planeswalker has a special connection to the magic in the Harry Potter world, like being able to sense the presence of magic in a way that wizards can't. They could use this ability to discover hidden secrets about Hogwarts or the wizarding families. Maybe a Planeswalker is on a quest in the multiverse and the Harry Potter world is just one stop on their journey, and their actions in the wizarding world have consequences for their overall mission.
