In a time - travel scenario, Anakin's relationship with his mother could be greatly altered. He could go back in time and save her from the Tusken Raiders. This would change his whole outlook on life and his path towards the dark side. Regarding his relationship with Palpatine, he would be aware of Palpatine's true nature from the start. So, he could either avoid Palpatine completely or try to expose him earlier. His relationship with other Jedi, like Ahsoka, could also be different. He could be a better teacher and mentor to her, as he has the experience of his future mistakes.
One idea could be Anakin traveling back in time to prevent his fall to the dark side. He could use his knowledge of the future to avoid the events that led him astray, like not trusting Palpatine. Another plot could involve him traveling to a time after his death and seeing the impact of his actions on the galaxy, which could be a moment of redemption for him. And perhaps he travels to a completely different era in the Star Wars universe and has to adapt to new cultures and powers while also dealing with his own inner turmoil.
One common theme is redemption. Since Anakin made so many mistakes in the original story, in time travel fics, he often tries to atone for his actions and make things right. For example, he might go back to save Padmé or prevent the rise of the Empire.
Obi - Wan Kenobi could be a great travel companion. Their relationship is so complex, and Obi - Wan could either be there to guide Anakin or to try and stop him from changing too much. Another possibility is Padmé. Since she was such an important part of Anakin's life, she could accompany him and influence his decisions during the time travel adventures.
Some fanfics might have Anakin time travel to a time when the Jedi Order was first founded. He could learn from the ancient Jedi teachings and bring that knowledge back to his own time to reform the Order. Or he could travel to a post - Galactic Empire era, seeing a galaxy that has either recovered or is still in chaos from his actions as Vader, which would be a huge motivation for him to go back and change things.
One great 'Star Wars Anakin Skywalker Time Travel Fanfiction' is 'Anakin's Second Chance'. In this fic, Anakin travels back in time and tries to correct his past mistakes. It's really interesting to see how his knowledge of the future affects his actions in the past.
In fanfiction, Anakin's character can be expanded through alternate timelines. Let's say a fanfic has him not turning to the dark side. We can then see how his character would have developed as a powerful Jedi without the influence of the Sith. It also allows for exploring his relationships with other characters like the clones in ways that the movies didn't fully cover. Writers can create scenarios where Anakin has to lead the clones in different battles and how that shapes his leadership skills and his view of the war.
One great Anakin Skywalker fanfiction is 'The Chosen One's Redemption'. It delves into Anakin's journey towards redemption after his fall to the dark side. It shows his internal struggles and how he tries to make amends for his past actions. Another is 'Anakin in Exile' which imagines Anakin living in seclusion and reflecting on his life. It gives a deeper look into his character outside of the main Star Wars narrative.
One idea could be a story where Anakin and Ahsoka are reunited after a long time apart. Maybe Anakin has been on a secret mission and Ahsoka has been exploring new parts of the galaxy. When they meet again, they have to work together to face a new threat that is endangering the Jedi Order.
One idea could be that Anakin travels to a future where the Jedi Order has been rebuilt in a new and unexpected way. He might initially be confused by the different teachings and practices. For example, the new Jedi might have a more inclusive approach, accepting Force - users from all walks of life, not just those trained from a young age as in his time. This could lead to Anakin having to re - evaluate his own understanding of the Force and his place in the Jedi legacy.
