One possible plot could be that Anakin somehow manages to escape the destruction of the Death Star at the last moment. Maybe he uses his strong connection to the Force to find a hidden escape pod or a secret passage. He then has to evade the Empire's search for him while also trying to figure out how to use this second chance to redeem himself further.
He would likely become more cautious. After surviving such a near - death experience on the Death Star, he would realize the true power of the Empire and be more careful in his actions against them. His redemption arc could continue as he tries to use his skills for the good of the galaxy, maybe by training new Jedi or helping the Rebellion in secret.
Well, Anakin started out as a very special kid on Tatooine. He was super good at fixing things and flying ships. The Jedi sensed his strong connection to the Force and took him in. Anakin grew up in the Jedi Order. He fought in the Clone Wars and became a great hero. But he was always haunted by his past and his emotions. His relationship with Padmé was a big factor. When he thought he could save her from dying by using the dark side powers, he made the wrong choice. This led to his transformation into Darth Vader, which changed the course of the Star Wars galaxy for a long time.
In many Star Wars fanfics, the relationship between Leia, Anakin, and the concept of a 'ghost' can be really interesting. Leia is Anakin's daughter, and in some fanfics, Anakin's ghost might play a role in guiding or protecting her. For example, he could appear to her at a crucial moment, sharing some wisdom from the Force that helps her make a difficult decision. This could add a new layer of depth to their family connection that wasn't fully explored in the movies.
Anakin can be redeemed in fanfiction by facing his past self. He might have a vision or an encounter where he sees the Jedi he used to be, full of hope and light. This confrontation makes him re - evaluate his choices and strive to return to the path of the Jedi, thus achieving redemption.
Yes, in some fanfictions, Rey is considered as Anakin's reincarnation. This idea often stems from the strong connection to the Force that both characters possess. There are fanfic writers who like to explore the concept of a spiritual or karmic cycle in the Star Wars universe, and this reincarnation theory is part of that exploration.
In such fanfiction, Anakin often makes different choices that lead him to use his powers for good. Maybe he avoids succumbing to the dark side and instead becomes a hero.
One great Dark Anakin fanfiction could be about his internal struggle. It might show how the dark side slowly creeps in as he faces difficult decisions in the Clone Wars. For example, a story could focus on a mission where he's tempted to use excessive force to achieve victory, and how that starts to change his mindset towards the dark side.
