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.
Perhaps Obi - Wan uses his Jedi skills in a creative way. For example, he could use a Force - related technique that shields Anakin from the influence of the Sith. He might create a sort of Force barrier around Anakin's mind, preventing the dark whispers from corrupting him further.
To develop Anakin's character, start with his disillusionment with the Jedi. He believes they have failed him, so his turn to the dark side seems like a way to gain the power he thinks he needs. In the Mustafar part of the fanfic, he can be shown as more impulsive and less in control of his emotions. Obi - Wan, on the other hand, can be developed as a character who is still holding onto hope that Anakin can be redeemed, but is also ready to do what is necessary to protect the galaxy.
Maybe the Force itself could be an antagonist in a sense. The light side of the Force would be trying to pull Obi - Wan back from the dark side. And the natural balance of the Force that doesn't want too much dark side influence could be working against Anakin's plan to turn Obi - Wan. So the Force, in its own way, could be the main antagonist.
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.
Well, 'The Unspoken Understanding' is a must - read 'anakin obi wan fanfiction'. It focuses on the unsaid emotions and the silent communication between the two. It beautifully portrays their friendship and the trust that was once there. Also, 'Anakin and Obi - Wan: Parallel Journeys' is really good as it shows their individual growth while still being connected to each other.
Another theme is the struggle between the light and dark side of the Force. Since Anakin eventually turned to the dark side, fanfics like to play with this idea. They might show Obi - Wan trying to bring Anakin back to the light, or Anakin trying to convince Obi - Wan that the dark side has its merits in certain situations.
Sure. In some fanfictions, a female Obi - Wan could have a more complex relationship with Anakin. Maybe she has to deal with the same challenges as the male Obi - Wan in the original, like Anakin's struggle with the dark side, but in a different way because of her being female. This could lead to some really interesting character developments and plot twists. Additionally, the way they communicate and interact with other characters in the Star Wars world might also change, making for a fresh take on the story.
In many Obi - Wan and Anakin fanfictions, the theme of mentorship is key. Obi - Wan's role as Anakin's teacher and guide is central. Also, the idea of destiny plays a part. Whether they can fulfill their destinies together or separately is a common plot point. Additionally, the theme of sacrifice is present, as both characters are in a position where they may have to sacrifice for the greater good or for each other.
