One key element is the power struggle. It's about showing how Sidious' immense power in the Dark Side of the Force clashes with Maul's own strength and determination. Another element could be the backstory, like how their relationship developed over time.
In most cases, Sidious would likely win. Sidious is extremely powerful in the Force and highly skilled in combat. He has been shown to manipulate events and people on a large scale. Maul, while a formidable opponent, is not as powerful or as devious as Sidious.
Maybe Sidious is trying to say that it's not just a simple fictional story. It could imply that the events related to him are real in the Star Wars universe in a sense. Like his rise to power, his manipulations, are all very real threats and not something to be dismissed as a made - up tale.
Well, it would make sense for some of Dooku's fellow Jedi from his early days to be in the story. Maybe Eeth Koth or Plo Koon. They could provide a contrast to Dooku's path. And on the Sith side, Savage Opress could be included. He had some interactions with Dooku. Also, Anakin Skywalker might make an appearance, as Dooku played a role in Anakin's journey, especially during their duels.
He could inherit the power of Force lightning. Darth Sidious was known for his powerful Force lightning attacks. In the Naruto universe, this could translate to some sort of unique chakra - based lightning attack that is far more powerful than the normal lightning - style jutsu. Also, Naruto might inherit some telekinetic abilities, being able to move objects with his mind or chakra, similar to how Sidious could use the Force for telekinesis.
One great 'anakin dooku fanfic' is 'The Duel Unseen'. It offers a unique perspective on their relationship and the events that could have happened between them.
Dooku died at the hands of Anakin Skywalker in the novel. Anakin, under certain circumstances and influenced by various factors, was the one who ended Dooku's life. This event had far - reaching consequences for Anakin's own character development as well.
Well, if Naruto were the grandson of Darth Sidious in this fanfiction, it would likely bring a dark and different dynamic to the Naruto universe. Naruto's typically positive and bright nature might be conflicted with the Sith influence from Darth Sidious. His values of friendship and hard work could be challenged as the Sith ways are more about power and domination. It could also change the power balance in the Hidden Leaf Village as Naruto might have access to different, perhaps more sinister powers, which would make his fellow ninjas view him differently.
Well, a great fanfiction idea could be that Darth Sidious discovers the existence of the wizarding world through some dark magic connection. He decides to conquer it, thinking it would be easy prey. But he underestimates the power of the Hogwarts students and their loyalty to each other. Harry Potter would be at the forefront of the resistance, using his skills and the support of his friends like Hermione and Ron.
One idea could be a crossover where Darth Sidious discovers the world of Naruto and tries to manipulate the ninja politics for his own gain. He might see the chakra system as a new source of power to exploit.
