One idea could be a story where the bound collar has a hidden magical power that only the wearer can unlock. For example, it might give the wearer the ability to communicate with magical creatures in a unique way.
Perhaps the bound collar is a part of an ancient ritual that was lost in time. In the fanfiction, the characters could be on a quest to discover the true meaning and origin of the collar. This could involve exploring long - forgotten tombs or ancient libraries in the wizarding world.
A really cool plot twist could be that the Bound Prince was cursed by an ancient magic long ago, and the only way to break the curse is for Harry to sacrifice something precious to him, like his invisibility cloak. This creates a moral dilemma for Harry and also throws a wrench in his usual problem - solving methods, making for a very engaging story line.
Some fanfictions might also involve the villains. Voldemort or his Death Eaters could be interested in the bound collar for their own evil purposes. They might try to steal it or use it against Harry and his friends, which would create a lot of conflict and action in the story.
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 a story where a character is wrongly accused and forced to wear a shock collar as a form of punishment. They then have to prove their innocence while dealing with the pain and limitations the collar imposes. For example, a small-time thief is framed for a big heist and the shock collar is used to keep them from running away while the investigation is ongoing.
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.
