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.
Anakin managed to defeat Dooku through a combination of his raw Force power and determination. He used his lightsaber skills and quick thinking to gain the upper hand.
In this fanfiction, the plot could center around Anakin's struggle with the two different ideologies of the Jedi and Dooku. Dooku, as his trainer, might expose Anakin to the Sith ways. This could lead to Anakin having internal conflicts, as he has to decide whether to stay loyal to the Jedi or follow Dooku's path. His training could involve learning more aggressive and unorthodox Force abilities that are frowned upon by the Jedi, and his interactions with Dooku could gradually change his view of the galaxy and his place in it.
Archive of Our Own (AO3) is also a great place to look for 'anakin dooku fanfic'. It has a well - organized tagging system which makes it easier to search for specific themes or types of stories related to Anakin and Dooku.

The main characters would surely be Anakin Skywalker and Count Dooku. Anakin is the protagonist in a sense as we would see his development through Dooku's training. Dooku, on the other hand, is the one who imparts his knowledge and skills, and his character would also be explored in terms of his motives for training Anakin.
One common theme is the power struggle. Anakin is a powerful Jedi and Grievous is a formidable foe. Their battle represents a clash of different kinds of power.
In a fanfiction where Naruto protects Naboo, he could use his ninja skills. Maybe he'd use his shadow clone jutsu to create distractions while he rescues Naboo from some sort of threat. For example, if there were invaders on Naboo, Naruto's clones could engage them in combat while he finds and safeguards Naboo.
Well, obviously Anakin and Vader are the main characters. Anakin is his pre - Darth Vader self, full of potential and hope at one point, and Vader is the dark, powerful Sith Lord he becomes.
One interesting plotline could be Anakin's struggle with his past self as Vader. Maybe in the fanfic, Anakin tries to prevent Vader from making the same mistakes he did, leading to intense battles of will and lightsaber duels.
It really depends on how you write it. If it's Anakin at his peak before turning to the dark side, he has a lot of raw power and potential. But Vader has years of experience as a Sith Lord. So, it could go either way.
