One popular theme is the redemption arc. Anakin's fall to the dark side and Luke's journey to bring him back in a way. Another theme could be the exploration of the Skywalker family legacy. How their powers and destinies are intertwined. Also, the theme of mentorship can be explored, like how Anakin could have been a different kind of mentor to Luke if he hadn't turned. There are also themes related to the struggle between the light and dark side within the family.
Anakin's development is complex. He has internal struggles that lead him to the dark side. His love for Padmé turns into a possessive and fearful thing. Luke, in contrast, develops in a more positive way. He faces challenges like the Emperor and Vader, but he uses his inner strength and the teachings of the Jedi to grow. He doesn't let his emotions overtake him like Anakin did. His development is more about self - discovery and mastering the Force for good.
Anakin Skywalker's story is one of great tragedy. Born into slavery, he had a difficult start. As a Jedi, he was in a relationship with Padmé Amidala, which was against the Jedi Code. His fall to the dark side was gradual. Palpatine manipulated him. He committed many atrocities as Darth Vader. But deep down, there was still good in him, which was shown when he sacrificed himself to destroy the Emperor.
One great 'Anakin Skywalker Fanfic' is 'The Chosen One's Redemption'. It shows Anakin's journey towards redemption in a really interesting way. It delves deep into his inner turmoil and how he tries to make up for his past mistakes.
Yes, in some fanfics, Anakin Skywalker is made out to be a descendant of Revan. Writers like to create these connections to add more depth and mystery to the Star Wars universe they're crafting in their stories.
One great Anakin Skywalker fanfic is 'The Fall and the Redemption'. It delves deep into Anakin's internal struggle between the light and dark side. Another is 'Anakin's Untold Journeys' which explores his relationships in a new light, especially with Obi - Wan. And 'Anakin: A Different Path' presents an alternate timeline for his character that is really interesting.
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.
There are some out there. However, the quality can vary greatly. Some might focus more on the romantic aspects between Anakin and the members of the harem, while others could be more action - packed with the harem aspect being a secondary plot. You really have to dig through different fanfic platforms to find the ones that suit your taste.
I really like the fanfic 'Anakin's Guidance for Rey'. In this story, Anakin, as a Force ghost, appears to Rey after she has started her Jedi training. He gives her advice on how to deal with the dark side of the Force, based on his own experiences. It has a lot of great dialogue and shows how Anakin has grown in his understanding of the Force even after his death.
Anakin's journey from Jedi to Sith and back again gives him a complex perspective. Other viewers might just see the battles as entertainment, but Anakin would likely see them through the lens of his own struggles with power, loyalty, and redemption. So, when watching the fanfiction, he could be constantly comparing the battles and characters to his own past actions and relationships, which is very different from the average viewer's more detached perspective.
