Well, if Obi Wan turned to the dark side in fanfiction, it would likely shake up the dynamics between him and the other Jedi. It might also change the outcome of many key battles and events in the Star Wars universe.
Well, if that happened, it would be chaos. The dynamics between Obi Wan and Luke, for example, would be completely upended. And it would raise questions about his motivations and how he could be redeemed, if at all.
One way could be to explore the idea of a great betrayal. Maybe a powerful Sith Lord manipulates events in such a way that Anakin and Obi - Wan both feel they have no other choice but to side with the Dark Side. For Anakin, it could be something related to his fear of losing Padmé, and for Obi - Wan, perhaps the Jedi Order's actions against him make him lose faith. The story could start with a series of small incidents that gradually push them towards the Dark Side.
A plot twist could be that they are joined by other Jedi who also believe that the Dark Side has been misjudged. Together, they form a new order that tries to balance the Light and Dark. But this new order is seen as a threat by both the Jedi and the Sith. So Anakin and Obi - Wan have to fight on two fronts, against those who once were their allies and against the true Sith Lords who want to use them for their own evil purposes.
Some popular themes in Dark Obi - Wan fanfiction include his fall to the dark side, his complex relationships with other characters like Anakin in a more twisted way. For example, exploring how his teachings might be corrupted and how that would impact Anakin's own journey further.
One great character to pair with Dark Obi - Wan is Darth Maul. Their confrontations in the official Star Wars lore were intense, and in fanfiction, they could form an uneasy alliance or continue their rivalry in new and interesting ways. Maybe they team up to take on the Jedi Council or something.
