One possible plot could be that Anakin is kidnapped by a secret Sith cult who wants to turn him fully to the dark side. They might use dark side magic to keep him imprisoned and try to manipulate his mind.
Maybe in the fanfiction, Anakin is kidnapped by a group of bounty hunters hired by a political enemy. The kidnappers try to use him as a bargaining chip to gain power in the Galactic Republic. This could lead to a rescue mission by his Jedi friends, with lots of action and suspense as they try to find his location.
A powerful crime syndicate could be responsible. They see Anakin as a valuable asset. Maybe they think they can sell him to the highest bidder, whether it's the Sith or some other powerful entity in the galaxy. They would use their extensive network of informants and thugs to carry out the kidnapping.
A third idea could be the story of her preparing for the arrival of her child in a galaxy filled with danger. She might have to find a safe haven, deal with the political implications of having a child in her situation, and face the potential threats from the dark side who might see her child as a target or a tool.
In some fanfictions, there might be a situation where Harry and Anakin are transported to a strange dimension that combines elements of both the Star Wars and Harry Potter universes. They might find themselves in Hogwarts but with the presence of Sith lords and Jedi knights. Here, they would need to use their wits and powers. Harry could use his knowledge of Hogwarts' secrets and Anakin his combat skills and understanding of the Force to navigate this new and dangerous world.
One interesting aspect in Emperor Anakin Skywalker fanfictions could be his rule over the galaxy. Some fanfictions might depict how he uses his new - found power to reshape the Jedi Order according to his own vision. He could be shown as a more tyrannical figure, with a completely different set of values compared to his former self as Anakin. Another common theme could be his relationships, like how he deals with Padmé in this new, dark role, or his interactions with former friends who are now his enemies.
One interesting Anakin Skywalker fanfiction could be one where he doesn't turn to the dark side. In this story, perhaps Padmé is able to convince him more firmly of the light. Another could be a time - travel fanfiction where Anakin goes back in time and tries to prevent the events that led to his downfall. There are also fanfictions that explore his relationship with Obi - Wan in more depth, like their adventures together as master and apprentice before the Clone Wars.
Some fanfics might explore Anakin's death as a result of his internal struggle. He has always been torn between the light and the dark side. Maybe in the fanfic, the dark side finally consumes him completely, but in that moment of total darkness, he realizes his mistake and sacrifices himself to stop the spread of evil that he has unknowingly helped create. This could be a very poignant and complex way to end his story, showing his journey full circle from a hopeful Jedi to a fallen Sith and back to a redeemed hero in his death.
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 interesting concept could be Anakin's Force presence during the events of Rebels. Maybe his spirit subtly guiding Ezra Bridger in some way. Since Anakin was the Chosen One, his connection to the Force is so profound that it could transcend time and space even after his death. Another idea might be a flashback scenario where the Rebels characters learn about Anakin's past deeds, both good and bad, and how it impacts their view of the Jedi Order. For example, they could discover how Anakin's fall to the Dark Side was a complex combination of his love for Padmé, his fear of losing her, and Palpatine's manipulation.
One interesting Anakin Skywalker Clone Wars fanfiction could be about his relationship with his clone troopers in more depth. For example, a story where he takes the time to really understand their individuality beyond their numbers and training. Another could focus on his inner struggle during the Clone Wars, like how he battles his own fears and insecurities while leading in the war. There are also fanfictions that might explore Anakin's interactions with other Jedi during this time, perhaps showing how his unique approach to the war is received by his peers.
Some fanfictions explore their relationship in the context of the Jedi Council. Since Anakin was often at odds with the Council, and Aayla was more in - line with the traditional Jedi ways, it creates an interesting dynamic. Maybe Anakin has an idea for a new strategy in the war, and Aayla has to decide whether to support him or side with the Council, which can lead to a lot of character development.
