In many fanfictions, Obi - Wan might use his deep knowledge of the Force. He could reach out to Anakin through a Force - bond, calming his inner turmoil and guiding him away from the dark side. For example, he might remind Anakin of their past together, their training, and the values they once held dear.
One interesting plot idea could be exploring Dooku's early days in the Sith. Maybe showing how he was gradually corrupted by Sidious. Another could be a story where Dooku has a change of heart briefly and tries to make amends in some small way during the Clone Wars, but is quickly pulled back into the dark side by Sidious' influence. A third idea could be a fanfic that focuses on Dooku's relationship with his former Jedi colleagues during the Clone Wars, like how he feels when facing them in battle.
If Anakin killed Obi Wan, it could have a domino effect. Anakin's relationship with other characters would likely change. Maybe the Jedi Order would crumble faster, and the Sith would gain more dominance. It's a fascinating 'what if' scenario to explore in fanfiction.
One possible fanfic could be about Obi - Wan's conflicted feelings between Satine and Siri. Maybe it shows how his Jedi duties and his relationships with these two important women in his life intersect. For example, a scenario where Satine's political situation in Mandalore forces Obi - Wan to make difficult choices, all while Siri, as a fellow Jedi, has her own take on the matter and how Obi - Wan should handle it.
In Clone Wars, Obi - Wan Kenobi's character is often focused on his Jedi duties. However, his interactions with Duchess Satine Kryze are often cited as having a love - like quality. Their past together and the way they still interacted during the Clone Wars, with Obi - Wan sometimes going out of his way to protect her, suggest that there was a special connection between them that could be considered part of a love story.
One interesting plotline could be a battle that takes place in an alternate universe where Anakin and Obi - Wan have different allegiances from the start. Maybe Anakin is a Sith Lord right from the beginning and Obi - Wan has to face his former apprentice in a more cut - throat battle.
Anakin and Obi - Wan could fit into a Marvel fanfic if they were part of a multiverse - spanning story. The Marvel universe already has concepts like the multiverse. They could be brought in as representatives of a different kind of power (the Force). Anakin's emotional and sometimes unpredictable nature could create interesting dynamics with the more stable Marvel heroes. Obi - Wan could act as a mediator between the two universes, using his knowledge of the Force and his diplomatic abilities to navigate the complex relationships in the Marvel world.
One common theme is loyalty. Their relationship was based on loyalty in the Jedi Order, but that loyalty gets tested as Anakin starts to turn to the dark side. Another theme is mentorship. Obi - Wan was Anakin's mentor, and fanfictions often explore how that mentorship influenced Anakin's growth and downfall.
There are indeed such fanfictions. Some of them focus on the deep bond between Anakin and Obi - Wan and re - imagine it in a different way. But these are mainly for the enjoyment of fans who like to explore alternative storylines and character dynamics within the Star Wars universe. Keep in mind that the official Star Wars story doesn't go in this direction.
Well, Anakin is often very well - written. His internal conflict between the light and dark side can be explored in great detail. His complex relationship with Obi - Wan, from being a beloved apprentice to a bitter enemy, gives a lot of room for character development. Writers can show his journey from a hopeful Jedi to a conflicted individual on the verge of falling to the dark side.
