Well, Anakin and Plagueis are the main ones for sure. Anakin is the protagonist in a sense as the story is about his training journey. Plagueis, on the other hand, is the antagonist in the context of the Jedi - Sith divide. However, other characters like Obi - Wan Kenobi could also play important roles in the fanfic. Obi - Wan might suspect something is wrong with Anakin's training or newfound abilities and try to investigate, adding more drama and conflict to the story.
The main characters would be Anakin Skywalker and Darth Plagueis. Anakin, a powerful Force - sensitive, is the focus of the training. Darth Plagueis, a Sith Lord, brings his knowledge of the dark side of the Force to the table. There may also be other supporting characters like the Jedi who might notice Anakin's change in behavior or Padmé, Anakin's love interest, who could be affected by his new training and the path he is on.
I'm not sure specifically as there could be many different takes in such a fanfic. But generally, it might involve Plagueis using his dark side knowledge and skills to train Anakin, perhaps leading Anakin down a different path in the Force compared to his canon training. Maybe Anakin would learn unique Force abilities or have a different view of the Sith and Jedi conflict.
Anakin's mother, Shmi, would likely be a very important character. Since Anakin is not being trained as a Jedi, he would be more focused on his family. Shmi's influence on Anakin would be even greater, and she could play a role in guiding his actions and decisions, especially in relation to the local community on Tatooine.
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.
Obviously, Anakin Skywalker and Revan. Anakin is the one being trained, so he will be a central figure. His growth and development under Revan's tutelage will be a major focus.
The main character is Darth Plagueis, of course. And Darth Sidious also plays a significant role as his apprentice.
The main characters are Naruto, the well - known ninja from the Hidden Leaf Village, and Vergil, who is likely from another realm or universe with his own set of powerful skills. In this fanfic, their interaction forms the core of the story as Naruto looks to Vergil for training and growth.
The main characters would be Percy and Atalanta. Percy is probably the protagonist who is undergoing training. Atalanta, on the other hand, is the one with the knowledge and skills to train Percy. There may be other supporting characters as well, but without reading the fanfic, it's hard to say for sure.
The main characters are obviously Percy and Madara. Percy is the one being trained, and Madara is the trainer.
Another plot could be that Anakin, without Jedi training, still has a connection to the Force but doesn't understand it. He might have strange dreams and premonitions that he tries to make sense of on his own. This could lead to him seeking out different kinds of mentors, not Jedi, but perhaps old hermits or wise women in the deserts of Tatooine who have a different perspective on the Force.
Darth Plagueis is the central character. His apprentice might also be considered a main character as their relationship is important in the story.
