Another plot could involve Obi - Wan traveling to the future. He might see a world where the Jedi have been completely wiped out and he has to find a way to bring them back. He could discover new Force abilities or meet descendants of the Jedi who have been hiding their powers all this time. This would be a great way to explore a different kind of Star Wars universe.
A really exciting plot could be Obi - Wan getting stuck in a time loop. Every time he tries to change something in the past, it just resets and he has to start all over again. In the process, he learns more about himself and the Force. He might also start to question if changing the past is really the right thing to do, as it could have unforeseen consequences for the future of the galaxy.
Well, here's a plot. Obi - Wan time travels to a parallel universe where the Sith won long ago. He has to find a way to get back to his own universe while also learning from this alternate reality. He might encounter different versions of characters he knows, like a more evil Anakin or a Jedi Order that has completely different values. This could lead to a lot of self - discovery for Obi - Wan as he tries to figure out how to restore balance in his own universe.
One idea is that Obi - Wan could be influenced by a powerful dark side entity. This entity could be a long - forgotten Sith spirit. It slowly corrupts his mind, making him question the Jedi teachings. He starts to see the Jedi's pacifism as a weakness. Another plot could be that Obi - Wan is framed for a heinous crime within the Jedi Order. Feeling betrayed by his own kind, he turns to the dark side to seek revenge.
One idea could be that the OC is a young Jedi in training and Obi - Wan becomes their mentor. They go on a mission together to a planet on the Outer Rim where they encounter a new Sith threat. The OC has a unique Force ability that Obi - Wan helps them to develop further, and in the process, they form a deep bond of friendship that could potentially turn into something more.
Time travel would likely make Obi - Wan more self - reflective. Seeing different versions of events and his own actions from different time periods would force him to reevaluate his beliefs and decisions. For example, if he goes back to his training days, he might realize things he could have done differently to be a better Jedi.
One interesting concept could be a crossover with the Star Trek universe. Imagine Obi - Wan using the Force in a world where technology and different species co - exist in a more scientific - based way. Another concept might be a crossover with the Lord of the Rings. Obi - Wan could bring his Jedi skills to Middle - earth and interact with the wizards and warriors there. Also, a crossover with the Harry Potter universe could be cool, with Obi - Wan teaching the young wizards about the Force which could be seen as a different form of magic.
In some 'dark Obi - Wan Kenobi fanfiction', he could be corrupted by a Sith Lord who manipulates his past traumas. The Sith might use his memories of the Clone Wars and his losses to push him towards the dark side. Obi - Wan would then have to fight not only the external influence but also his own demons as he descends into a darker version of himself.
One interesting plot idea could be Obi - Wan traveling back in time to his days as a Padawan. He could use his future knowledge to avoid certain mistakes or better understand his relationship with Qui - Gon Jinn. For example, he might be able to prevent some small misunderstandings that had a big impact on his training. Another idea is that he travels to a time during the Clone Wars but with a different perspective. He could try to change the outcome of certain battles in a more strategic way, knowing what the future holds. A third idea could be Obi - Wan traveling to a time long before the events of the movies, like during the Old Republic era, and getting involved in ancient Jedi - Sith conflicts, bringing his modern - day Jedi values to an older time.
There might be a fanfiction where Obi - Wan's reaction to the destruction of the Jedi Order is explored in great detail. It could involve his efforts to save as many Jedi as possible and his feelings of guilt and determination at the same time. He might have to make some really tough decisions, and the fanfiction could show how he copes with all that.
The different types of characters he could fall in love with make it interesting. Whether it's another Jedi, a civilian, or an alien, each brings a different dynamic to the story. For example, if it's another Jedi, they can understand each other's connection to the Force better. If it's a civilian, there's the aspect of introducing the Jedi world to someone outside of it.
One idea could be a scenario where Obi - Wan is captured by the Sith. His hands are bound, but he uses the Force to communicate secretly with his allies. He might try to outwit his captors through his Jedi wisdom and mental strength.
