One idea could be Harry using parkour skills to escape from the Death Eaters in the Forbidden Forest. He jumps from tree to tree, slides under fallen logs, and uses his magic to enhance his physical abilities for parkour.
Maybe a story where Hermione decides to learn parkour to be more physically fit for the battles against Voldemort. She then teaches parkour to the other members of Dumbledore's Army, and they use it to their advantage during a raid on a Death Eater stronghold. They can quickly move around the complex architecture of the stronghold using parkour moves.
A plot could involve a new character who is a parkour expert from the Muggle world. This character somehow stumbles into the wizarding world and befriends Harry. Together, they combine magic and parkour to explore hidden areas of Hogwarts, like the secret passages that are difficult to reach without the acrobatic skills of parkour.
One idea could be Naruto using his parkour skills to escape from Orochimaru's lair. He jumps from tree to tree, wall - runs along the cave walls, and uses his ninja agility in a new and exciting way.
One idea could be Harry using parkour skills to escape from the Death Eaters in the Forbidden Forest. He jumps from tree to tree, slides under fallen logs, and uses his magical abilities in combination with his newfound parkour skills to outmaneuver them.
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 be Naruto is sent on a mission in a foreign land full of tall buildings and narrow alleys. He has to use parkour to chase a rogue ninja through the city. Since he's not familiar with the terrain, he has to quickly adapt his parkour moves. For example, he might have to use his shadow clones to create distractions while he makes risky jumps from rooftop to rooftop.
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.
One idea could be Harry Potter using his wizard skills in a boxing ring in a unique way. For example, he might use a levitation charm to dodge punches or use a stunning spell on his opponent's gloves to make them heavier. Another could be a story where the wizarding world has its own boxing league and Harry has to compete against other magical beings like werewolves or giants in the ring.
An enchanter in a fanfiction could create a spell that allows them to communicate with portraits in a way that has never been done before. For example, they could get advice from portraits of long - dead headmasters on how to deal with the current political situation in the wizarding world. Another plot might be that an enchanter is able to enchant the Sorting Hat to sort students based on their future potential rather than their current characteristics. This could lead to some students being placed in houses that they never expected. And finally, an enchanter could be working on a spell to make the Hogwarts Express invisible during its journey, but things go wrong and the train starts to disappear and reappear at random intervals, causing panic among the students.
One idea could be that Amara is a new student at Hogwarts with a special power to communicate with magical creatures in a way no one else can. Harry discovers this and they team up to solve a mystery involving a group of sickly unicorns in the Forbidden Forest.
One idea could be a wedding between a wizard from Gryffindor and a witch from Slytherin, which could cause a stir among the Hogwarts alumni. They might have to overcome the old prejudices of their houses. Another could be a wedding set during a time of peace after the battle of Hogwarts, with characters like Harry and Ginny as guests, and the wedding could incorporate a lot of traditional wizarding wedding elements like flying doves made of light magic.
One idea could be that Lelouch, with his strategic mind, somehow gets transported to the Harry Potter world. He could use his Geass ability in a very different way, like influencing Death Eaters to turn against Voldemort. Another could be Harry Potter and Lelouch teaming up to fight a common enemy that has elements of both their worlds, perhaps a dark wizard who has also mastered some form of mind - control magic similar to Geass.
