Force wielders in Star Wars balance force and destiny in different ways. Jedi like Obi - Wan Kenobi have a strong sense of duty. They know their destiny is to oppose the Sith and keep the peace. They use the force in a controlled and ethical way. Sith, though they may seem unbalanced, also think they are following their destiny. They believe in using the force to gain power and rule, but this often leads to their downfall in the long run. In general, it's about how they perceive their purpose in the grand scheme of the Star Wars universe and how they use the force to achieve it.
One main theme is redemption. Since the Force 'loves' Anakin, it often leads to stories where he is being guided towards redemption. Another theme could be destiny, as the Force's love for him might be related to his important role in the galaxy.
Yes, there are quite a few. You can start by looking on popular fanfiction websites like FanFiction.net or Archive of Our Own. Just search for 'the force loves anakin' and you'll find a variety of stories, each with its own take on this concept.
In anakin force ghost fanfic, the theme of hope is often present. His existence as a Force Ghost gives hope to those who are still fighting for good. Another common theme is the exploration of the Force. As a Force Ghost, Anakin has a deeper understanding of the Force, and fanfics often use this to explore different aspects of the Force. There's also the theme of forgiveness. Anakin has to seek forgiveness from those he wronged, and this journey of seeking forgiveness is a common plot in many fanfics.
One story could be that a mother wants her daughter to bring friends home so she can get to know her daughter's social circle better. Maybe she's worried about her daughter making bad friends and by having them over, she can observe and guide. Another could be a father who hopes his daughter's friends will come over to boost his daughter's confidence, showing that she has a great family and support system.
One great Anakin Force Ghost fanfic is 'The Redemption of Anakin Skywalker in the Afterlife'. It delves into how Anakin, as a Force Ghost, tries to right his past wrongs in the spiritual realm. Another is 'Anakin's Guidance', where he appears as a Force Ghost to guide a young Jedi. There's also 'Force Ghost Anakin: A New Hope', which shows Anakin using his spectral form to influence the future of the galaxy for the better.
The characters in 'The Force Awakens' would have very different reactions to Anakin's sudden appearance. Rey, being so eager to learn about the Force, would likely be in awe and immediately want to learn from him. Finn, on the other hand, might be a bit more cautious at first, but would soon realize Anakin's value in the fight against the First Order. Poe would probably be excited to have such a powerful ally on their side.
In some fanfics, a unique plot point is Anakin's past actions being revealed to a new generation in the 'Force Awakens' time. This includes his fall and redemption, and how it impacts the characters like Leia who are still dealing with the aftermath.
There is a fanfic named 'Leia's Connection to Anakin in the Force Awakens'. It focuses on exploring the family connection between Leia and Anakin in the context of the events in 'Force Awakens'. It shows how Leia's knowledge of her father shapes her actions and decisions in this new era of the Star Wars universe.
Anakin in 'The Force Awakens' via time travel would be a game - changer. Just think about it. His connection to the Force is so strong. He could sense Snoke's true nature and expose him early on. This would disrupt the First Order's plans. And with his combat skills, he could take on the Knights of Ren single - handedly, or at least give the Resistance a huge advantage in battles.
