The special thing is the combination of two different universes. Harry Potter is known for its magic and Hogwarts, while Sith are all about the dark side of the Force in Star Wars. Merging these two concepts makes it stand out.
Yes, it could be. If it portrays Harry Potter in an interesting and unique way as a powerful Sith, it might attract a lot of fans. The combination of two very different and popular universes, Harry Potter and Star Wars (where Sith are from), can be quite appealing.
Well, if the Sith were more powerful, it could lead to a complete shift in the balance of power in the galaxy. Maybe the Jedi would struggle even more to maintain peace and justice.
In Clone Wars fanfiction, Darth Maul stands out. He was initially thought to be dead after 'The Phantom Menace' but his return in Clone Wars brought a new level of danger. His thirst for revenge against Obi - Wan Kenobi and his attempts to regain his former power are common themes. Darth Sidious is also key. His devious plans to create chaos and gain ultimate power are often explored in fanfiction. He was using the Clone Wars as a means to an end, and fan writers love to play with the idea of what his true endgame was.
The duel between Darth Maul and Obi - Wan Kenobi is a famous Sith - related story. Their first encounter on Naboo was intense. Maul's acrobatic fighting style and his double - bladed lightsaber against Obi - Wan's skills made for an epic battle. And Maul's later return added more depth to his story as a Sith.
The Darth Revan story is quite outstanding. Revan was such a powerful and complex figure. His journey from a great Jedi to a Sith Lord and then back to a more ambiguous state was full of mystery. His influence on the SWTOR universe is huge, and his story has elements of redemption, power struggle, and the exploration of the Force that make it a standout among Sith stories.
Perhaps there are some neutral characters who get caught in the middle of the conflict between the Sith and the Jedi. They could be ordinary people, or they could be some other species in the Star Wars galaxy that are trying to survive the chaos that the Sith Lords bring with their power - hungry ways.
In some 'Harry Potter Sith fanfiction', a plot twist could be that a seemingly good character is actually being influenced by Sith powers all along. For example, a teacher at Hogwarts who is secretly using Sith mind - control techniques on students to further their own dark agenda.
In Naruto Sith Lord fanfiction, a great plot twist might be that Naruto's friends secretly join him in his Sith - like ways, thinking they can control the dark side. Or perhaps Naruto finds out that the Hokage have been hiding knowledge of the Sith all along. It would also be interesting if Naruto uses his Sith powers to bring back dead characters, but they come back with a dark and unpredictable nature.
