One popular 'Anakin kidnapped' fanfic might be 'The Rescue of Anakin'. It could involve his friends or allies trying to save him from the captors. Another could be 'Anakin's Abduction and the Jedi's Quest', where the Jedi Order undertakes a dangerous mission to bring him back.
It could be the Separatists. They might see Anakin as a valuable hostage to use against the Jedi and the Republic. His skills as a Jedi Knight make him a prime target for them to gain some sort of leverage in the war.
One possible plot development could be that his friends immediately launch a rescue mission. They might use their unique skills and resources to track down the kidnappers. For example, if Obi - Wan is involved, he could use his Jedi mind tricks to interrogate possible informants in the underworld.
There could be a hermit or an outcast Jedi or Sith on Dathomir. Anakin meeting this character could lead to a great revelation. Maybe this character has been in hiding on Dathomir for years, observing the balance of the Force there, and Anakin's arrival disrupts that balance and forces an interaction that changes Anakin's perspective on many things.
One great Ahsoka and Anakin fanfic is 'The Apprentice's Journey'. It delves into their relationship during their time as master and apprentice. It shows Anakin's complex emotions towards Ahsoka, his pride in her growth as a Jedi, and also his protective instincts. The story is filled with action scenes that they face together, and the character development is really well - done.
In fanfics about Ventress and Anakin, their relationship is often complex. They are on opposite sides in the Star Wars universe, but fanfic writers like to explore what could happen if they had more interactions. Sometimes they might be portrayed as rivals with a grudging respect for each other's skills.
Yes, in many fanfics Anakin is often depicted as an extremely skilled pilot. His natural talent and Force - enhanced reflexes give him an edge in the cockpit, making him a formidable force in space battles.
In some fanfics, it could be Anakin's own self - destructive tendencies. He has made so many bad choices in his life that in the end, his own actions lead to his death. For example, if he continues to pursue the dark side without fully understanding its consequences, it could ultimately consume him and lead to his demise.
Anakin's mother, Shmi, would likely be a very important character. Since Anakin is not being trained as a Jedi, he would be more focused on his family. Shmi's influence on Anakin would be even greater, and she could play a role in guiding his actions and decisions, especially in relation to the local community on Tatooine.
They might find an ally within the place where they are held. There could be another being there, maybe an angel who doesn't agree with Castiel's actions, or a human who has also been captured by Castiel in the past and knows the layout well. Together, they could come up with an escape plan.
