Darth Revan might see Anakin as a powerful tool. He could try to manipulate Anakin further towards the dark side, using his own experiences of falling to the dark side to tempt Anakin. Maybe he would offer Anakin power beyond his wildest dreams if he fully embraced the dark side.
In such a fanfiction, one possibility is that Anakin Skywalker might initially be in shock upon seeing Darth Vader. He could struggle to come to terms with what he has become. Maybe there would be a battle of wills as Anakin tries to fight against the dark side within Vader.
In my opinion, they're quite good. They expand on Darth Maul's character and provide some intense action scenes. The writing and illustrations work well together to create an engaging experience.
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.
Luke Skywalker could be another key character. Since he is Vader's son, his presence could add an interesting dynamic. He might be the one who somehow triggers the battle between Anakin and Vader, or he could be in a position to influence the outcome of their fight, perhaps by appealing to the remaining good in Anakin or by facing off against Vader himself in a three - way struggle.
Well, Anakin Skywalker's journey to becoming Darth Vader was a complex one. He was a slave on Tatooine as a child, and his strong Force abilities were noticed early. He was taken under the wing of the Jedi. But his mother's death, his love for Padmé, and the political intrigue in the galaxy all played a part. The Jedi's distrust of him and Palpatine's insidious influence pushed him over the edge. He believed that the dark side could give him the power to prevent the loss of those he loved, so he embraced it, thus becoming Darth Vader.
Maybe some of the Jedi who cross paths with Darth Maul, like Qui - Gon Jinn. Their interactions are important in the Star Wars universe. Also, there could be other Sith or dark side characters who are part of Maul's story, perhaps his own apprentices if he has any at some point in the story.
Darth Sidious is an important character. He is Darth Maul's master and plays a crucial role in guiding Maul's actions and training. Another one could be some of the Jedi that Maul encounters during his missions. They are his opponents and their interactions are significant.
He might have some underworld contacts as allies. People who are also outcasts in the galaxy and see value in aligning with a powerful Sith like Darth Maul.
