One common theme is the struggle with the dark side. Both Anakin and Kylo have had their battles with the dark side of the Force. Fanfics often explore how they deal with it, either succumbing or trying to resist.
Another theme is the idea of legacy. Anakin is a very important figure in the Star Wars universe, and Kylo is a later - generation character. Fanfics might look at how Anakin's actions and reputation impact Kylo, or how Kylo might be seen as either continuing or breaking Anakin's legacy.
Power is a common theme. Just like the male Kylo Ren, the female version often struggles with her power, whether it's the power of the Force or political power within the Star Wars universe.
Redemption is another theme that can be found. Kylo Ren's journey in these fanfics as a bottom might involve him trying to make up for his past actions. His relationships and experiences in this role can be a catalyst for his redemption arc. The way the authors write about his transformation and growth in relation to these themes makes the fanfics very engaging.
Another theme is the exploration of the Force in relation to the relationship. Since both Kylo and often the reader (if given some Force - related abilities) are connected to the Force, the fic may explore how their connection through the Force affects their relationship. It could be like they can sense each other's emotions more strongly because of their Force bond.
Another theme is atonement. Anakin tries to make up for the bad things he has done. This can be through protecting the galaxy from new threats or helping to rebuild the Jedi Order. In some fanfics, he'll train new Jedi as a way of redeeming himself for his past destruction of the Order.
Well, a very common theme is the internal struggle. Anakin is constantly fighting within himself in these fanfics. There's also the theme of loyalty, whether it's his loyalty to the Sith or any remaining loyalty to his Jedi past. And the theme of revenge often comes up, as he might seek revenge on those he feels wronged him as a Sith.
One common theme is the loss of control. Anakin's anger often leads to him losing control of his actions and decisions. Another theme is the isolation it causes. As he gets angrier, he pushes away those who care about him, like his friends in the Jedi Order.
One common theme is mentorship. Anakin was Ahsoka's master, so fanfics often explore how he guided her and the lessons she learned from him. Another theme is loyalty. Their loyalty to each other, especially in difficult situations, is often a big part of these stories.
One common theme is mentorship. Anakin often acts as a mentor to Ashoka, guiding her in the ways of the Force. Another theme is friendship. Their relationship is a deep friendship that withstands many challenges. For example, in some fanfics, they support each other during difficult battles or when facing political intrigue within the Jedi Order.
A frequent theme in child Anakin fanfic is his life on Tatooine. This includes his experiences as a slave, his dreams of a different life, and the people he meets on the desert planet. Also, the idea of Anakin being a chosen one is often explored. How does he start to realize his special destiny? And how do others around him react to this potential? These are all aspects that are commonly written about.
One common theme is the fear of losing loved ones. Since Anakin has a strong emotional bond with Padmé, his nightmares often revolve around her being in danger or lost to him. This theme reflects his deep - seated insecurities.
