One idea could be that a Sith Lord somehow infiltrates Hogwarts. Maybe he uses the Dark Arts in a way that the wizards have never seen before, creating chaos. Another could be a wizard being tempted by the Sith Lord's power and turning to the dark side, much like in Star Wars. They might start using their magic in cruel ways.
One idea could be a young wizard from Hogwarts being secretly recruited by a Sith Lord. Maybe they discover a hidden connection between the Dark Side of the Force and some of the darkest magic in the wizarding world, like the Unforgivable Curses. The wizard, as a Sith apprentice, could then start using Sith powers alongside magic, creating a whole new kind of chaos in both the Star Wars and Harry Potter universes.
One idea is that a young Sith apprentice gets lost in a magical portal and ends up in the Harry Potter universe. This apprentice then tries to find a way back to the Sith Empire while causing chaos in the wizarding world. Some wizards might be intrigued by the apprentice's dark powers and start to follow him, leading to a split in the wizarding community between those who support the Sith ways and those who oppose them.
One interesting idea could be the clash of different magical and dark side elements. The Harry Potter universe has its own magic system, and the Sith from Star Wars bring a different kind of dark power. In a harem aspect, perhaps different female characters from both universes are brought together, each with their own skills and personalities, creating unique interactions and storylines.
One idea could be a crossover between a Sith Lord and a superhero universe. The Sith Lord's dark powers and manipulation skills would create an interesting dynamic against the heroes. For example, a Sith Lord in the Marvel Universe could try to turn some of the anti - heroes to the dark side.
One interesting plot idea could be a crossover where the magic from Harry Potter is combined with the unique elements of the 'Lord of the North' setting. For example, Harry and his friends could encounter new magical creatures specific to that northern realm while on a quest.
A possible plot in 'evil lord harry potter fanfiction' is that Harry discovers a long - lost and very powerful dark magic artifact. With this artifact, he decides to challenge the existing power structure of the wizarding world. He begins to gather followers who are attracted to his new - found power and his bold ideas of changing the status quo. He might even face off against Dumbledore and the Order of the Phoenix in a very different kind of battle, not the typical good - versus - evil battle but a more complex power struggle.
In the 'Harry Potter Lord of Domination' fanfiction, a possible plot could be that Voldemort returns in a new form, influenced by the idea of the 'Lord of Domination'. He finds a way to control not just the minds of individual wizards but entire wizarding institutions. Harry and his friends then have to seek help from unlikely sources, maybe even from other magical creatures that are immune to this new form of domination. They embark on a journey to find a way to break Voldemort's hold over the wizarding world once and for all.
One idea could be a fanfiction where Voldemort gets a second chance at life but without his dark magic powers. He has to learn to live as a normal wizard in the wizarding world and Harry Potter has to decide whether to trust him or not.
One interesting plot could be the main character using time - traveling magic from the Harry Potter world to change key events in the Lord of the Time's story. For example, they might go back to prevent a certain dark wizard from obtaining a powerful time - related artifact.
One interesting concept could be a crossover where the magic of Harry Potter's world interacts with the Force in the Sith's domain. Maybe Harry discovers a hidden connection between his wizarding abilities and the dark side of the Force, leading to a struggle within himself as he's tempted by the power the Dark Lord of the Sith represents. Another concept could be a battle of ideologies, with the values of Hogwarts clashing against the Sith's teachings of power through domination.
