There might be a fanfiction where Ahsoka tries to redeem Maul. Given her Jedi - like nature, she could see the good in him that was once there before he fully turned to the dark side. This would involve a lot of emotional exchanges and battles within Maul's mind as he struggles with his past and the possibility of redemption.
In a fanfic, perhaps there is a time - travel element. Ahsoka is sent back in time and ends up meeting Darth Vader when he was still Anakin. She tries to prevent him from turning to the dark side. This would be a complex story as it would involve her trying to change the course of events without disrupting too much of the timeline.
A possible plot could be that Ahsoka is captured by the Empire. Darth Vader is then tasked with interrogating her. But as he does, memories of their past start to resurface. He begins to question his loyalty to the Emperor and whether he should let Ahsoka go free.
One possible storyline could be a scenario where Ahsoka Tano and Darth Vader cross paths during a mission on a neutral planet. Ahsoka, still holding onto her Jedi beliefs, tries to reach out to the conflicted Anakin within Vader. This could lead to intense lightsaber duels and deep, emotional exchanges as they both struggle with their past relationship and the current state of the galaxy.
A plot idea could be that Maul discovers a prophecy that involves Ahsoka and he decides to either protect or manipulate her depending on how he interprets it. This could lead to a complex relationship where Ahsoka is initially distrustful but then realizes Maul's motives are more nuanced.
In some fanfictions, their relationship develops through a series of battles. Each encounter makes them more aware of the other's strength and weaknesses. For example, Vader might initially see Ahsoka as a mere nuisance but as they fight more, he starts to respect her skills, which in turn makes him question his own choices more deeply. And Ahsoka, she begins to understand the depth of Vader's fall and feels a sense of sorrow for him.
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.
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.
