One idea could be a story where a student who is usually very unlucky gets ahold of Felix Felicis. They use it to turn their academic and social life around, but then face the challenge of whether their newfound success is truly theirs or just the result of the potion.
Perhaps a fanfiction where Felix Felicis is stolen from the Potions classroom and there's a mystery to find out who took it. Different characters, like Hermione, could use their detective skills to solve the case, all while the potion is being misused in the background creating chaos around Hogwarts.
A story could revolve around a character who is forced to make a very difficult decision and uses Felix Felicis to gain the confidence to do it. But they soon realize that the potion's influence doesn't make the consequences of their decision any easier to bear. They then have to figure out how to deal with the aftermath without relying on the potion.
One interesting plot could be a character using the permanent Felix Felicis to solve a long - forgotten mystery in the wizarding world. For example, they might discover the true origin of an ancient spell that has been lost in time. Another could involve a student using it to always ace their exams and then getting into some trouble when the professors suspect foul play.
A really cool plot could be where the Permanent Felix Felicis has some unforeseen side - effects. Instead of just bringing good luck, it starts to warp reality in small ways. The main character has to figure out how to reverse or control these effects while also dealing with the regular challenges at Hogwarts like exams and rivalries. This would add an element of mystery and danger to the story, making it more exciting.
Hermione Granger is also a popular choice. Given her intelligence and love for learning about potions, it's easy to imagine her either creating more Felix Felicis or using it in a clever way to solve a problem at Hogwarts.
In many 'Harry Potter Permanent Felix Felicis Fanfiction', Ron Weasley could be one of the main characters. He often gets into all sorts of situations with Harry and Hermione, and with the addition of the permanent Felix Felicis, his character could have some really interesting developments. Additionally, some original characters created by the fanfiction authors might be main characters. These could be new students at Hogwarts who discover the permanent Felix Felicis and have to deal with the consequences.
Hermione Granger could also be a central figure. Given her intelligence and thirst for knowledge, she could be researching the Permanent Felix Felicis and its implications, and might accidentally consume it or use it in an experiment. She would then use her wits along with the potion's effects to navigate through various situations.
Here are some plot ideas. Felix and Marinette could be paired up for a dance competition at school. At first, they are both reluctant, but as they practice, they develop feelings for each other. Another idea is that there's a new villain in town who targets Marinette specifically because of her connection to the Miraculous. Felix, being the observant person he is, notices the strange things happening around Marinette and decides to help her. He might even pretend to be her bodyguard. And finally, a story where Felix and Marinette accidentally swap bodies due to a magical mishap. They have to figure out how to reverse it while also dealing with each other's lives and responsibilities.
One plot idea could be that Felix, instead of being a villain, becomes Bella's secret protector in the Twilight world. He might sense some unique power within her that even the Cullens are unaware of. This could lead to a series of adventures where they have to hide their alliance from both the Volturi and the Cullens.
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.
