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.

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.

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.
A traveler could be from a different magical realm entirely and come to the Harry Potter universe.

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.
One interesting plot could be a time - travel story in the Harry Potter wonderland. For example, a character goes back in time to the Marauders' era and gets involved in their adventures, while also trying to prevent a future disaster in the wizarding world. Another idea is a story where a new, powerful magic is discovered in the wonderland, and Harry and his friends have to figure out how to control it before it falls into the wrong hands.
