In this fanfiction, the faceless man could be an experiment gone wrong by a dark wizard in the past. He has lost his face as a result of a powerful but unstable spell. He then crosses paths with Harry Potter. The faceless man might hold the key to a powerful magic that could help Harry in his fight against the Death Eaters. But Harry has to first figure out how to communicate with him and earn his trust, as the faceless man has been shunned by the wizarding community for so long.
Well, perhaps the faceless man is a time - traveler from a far - off future of the Harry Potter universe. He comes back to Harry's time with knowledge of a great disaster that's about to befall the wizarding world. He tries to guide Harry in a way that will change the future, but his faceless nature makes him seem very mysterious and untrustworthy at first. Harry has to decide whether to trust this strange being or not, which could lead to a really interesting story.
He could be a wizard who made a deal with a powerful magical entity. In exchange for great power, he lost his face. Now, he appears in the story of Harry Potter, and his presence might be a sign of a greater, more complex plot involving power struggles within the wizarding world that Harry will eventually get caught up in.
There could be a fanfiction where the Faceless Man is a time - traveler. He travels through different eras in the Harry Potter universe, influencing events in ways that no one realizes. For example, he could be the reason some spells were created or some dark wizards were defeated in the past, all while remaining faceless and mysterious.
He could be an ancient wizard who was cursed and lost his face. In the fanfiction, this wizard might be seeking a way to reverse the curse and his journey intersects with Harry Potter's adventures.
A cool plot could be that the Venom symbiote attaches itself to a wizard. This wizard - Venom hybrid starts causing chaos in both the wizarding world and New York. Spider - Man and Harry Potter have to work together to figure out how to separate the symbiote from the wizard. They might have to combine magic and science to achieve this.
One idea could be Arya using her Faceless Man skills to avenge the wrongs done to her family. She could infiltrate the enemies' strongholds unnoticed and take them out one by one.
One idea could be that the Exorcists from D Gray - Man end up in the wizarding world of Harry Potter. They might team up with the Order of the Phoenix to fight against a new threat that combines the dark magic of the Death Eaters and the Akuma from D Gray - Man.
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 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.
