A plot could involve a student accidentally creating a new type of monster by mixing spells. This new monster has unique abilities and it's up to Harry and his friends to figure out how to deal with it. They might need to study old books in the restricted section to find a solution. For example, they could discover that the monster is sensitive to a certain type of music, which they can use to calm it down.
One idea could be a story where the monsters in Hogwarts form an alliance to protect the school from a new dark threat. Maybe the trolls, centaurs, and merpeople work together with the students.
Perhaps there could be a tournament where the students have to combine their wizarding skills with Duel Monsters strategies. A character could be really good at using Fire - based spells and then pairs that with Fire - type Duel Monsters cards. They would need to learn how to balance the two forms of combat to win the tournament.
One idea could be that Harry discovers he has the power to control monsters deep in the Forbidden Forest. He uses this new ability to protect Hogwarts from a dark wizard who is summoning dangerous creatures.
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 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.
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. A third plot could be about an alternate reality where Voldemort won the war, and the remaining good characters have to find a way to reverse the situation in the harry potter wonderland.
One plot idea could be that Bella discovers she has a hidden magical ability that only Harry can help her understand and control. Maybe it has something to do with an ancient magic that's connected to Harry's destiny.
One interesting plot idea could be a fanfiction where the magic system in Harry Potter is reversed. Instead of wands being the main tool for magic, it's potions that can directly create magical effects without the need for incantations. Another could be a story where characters from different houses have to team up to solve a mystery that involves a new, never - before - seen type of magic that is slowly corrupting Hogwarts. And there could also be a fanfic where a Muggle - born discovers a way to use modern technology in combination with magic, creating a whole new form of spell - casting.
