A great plot for a Harry Potter reunion fanfiction could be centered around a magical competition among the old friends. They gather at Hogwarts for this event. There are different challenges that test not only their magical skills but also their friendships. For example, one challenge could be to face their greatest fears together, which would bring back a lot of memories from their school days. Along the way, there could be some romantic rekindlings, like Harry and Ginny reminiscing about their relationship and how it has grown over the years.
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 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.
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 idea could be that Hermione discovers long - lost relatives who are also powerful wizards or witches. Maybe they have unique magical abilities that Hermione has never seen before. They could gather for a reunion at a magical location, like an ancient family castle hidden in the Scottish Highlands.
One idea could be that Hermione attends a muggle high school reunion. She has to hide her magical abilities but accidentally uses magic when an old bully starts to harass her. Another could be she meets an old muggle friend who has a mysterious ailment, and she secretly uses magic to heal them while trying not to expose the wizarding world.
One idea could be that the main characters reunite during a big Pokemon tournament. They each have new Pokemon and strategies, and they compete against each other in an epic battle. It could also be a reunion during a crisis, like a natural disaster in the Pokemon world, and they have to work together to save Pokemon and people.
One idea could be that the boys reunite for a special charity concert. They each bring their own unique musical growth from their solo careers and blend it into a new sound for the concert. It could be a chance to heal old wounds and reignite their friendship on stage in front of their fans.
