A really interesting plot could be Anakin getting lost in the dark side for a short time and Obi - Wan trying to bring him back. It could explore their relationship on a deeper level, showing Obi - Wan's loyalty and Anakin's internal struggle. There could also be a fanfiction where they are stranded on a strange planet together and have to rely on each other to survive, facing all kinds of alien creatures and harsh environments.
One great storyline could be Anakin and Obi - Wan teaming up against a new Sith threat that is more powerful than they initially thought. They have to put aside their differences and combine their skills, with Obi - Wan's calm and calculated approach and Anakin's raw power. Another could be a pre -quel type of fanfiction where we see their early days of training together in more detail, like how they overcame certain challenges during their training sessions.
Some fanfictions focus on alternate universes. For example, what if Anakin didn't turn to the dark side and he and Obi - Wan went on to become the most powerful Jedi duo in the galaxy? They could travel around, solving problems and spreading peace. This would show a very different side to their relationship compared to what we saw in the movies, with more trust and mutual respect.
One interesting storyline could be exploring their relationship during Anakin's early days as a Padawan. It could show Obi - Wan's struggle to train a headstrong Anakin while also dealing with his own insecurities. Maybe there are adventures where they face a new Sith threat together and Anakin has to learn to control his emotions in the heat of 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 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.
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.
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.
One common theme is the exploration of their unspoken bond. In the movies, they have a deep connection, and in fanfiction, it can be turned into a more romantic or homoerotic bond. Another theme could be the conflict between their duties and their feelings for each other.
I really like 'Anakin and Obi - Wan: The Lost Chapters'. This fanfiction fills in some of the gaps in their story that the movies didn't cover. For example, it shows some of their adventures during the Clone Wars that weren't shown on - screen. It also has great character development for both of them, making their relationship more complex and believable.
A popular fanfiction idea is Anakin and Padme getting married in a more elaborate and secret ceremony. They invite a few close friends like Obi - Wan (who has mixed feelings but respects their love). This storyline could explore their domestic life and how they try to keep their relationship hidden from the Jedi Council.
One interesting storyline could be Obi - Wan secretly guiding a young character from Star Wars Rebels in the ways of the Force without revealing his identity. This would add an element of mystery and mentorship to the story.
The Sith, definitely. They are always the main antagonists in the Star Wars universe, and in this fanfiction, they would be the ones trying to keep Anakin on the dark side. Palpatine, in particular, would be a major antagonist as he was the one who manipulated Anakin in the original story.
