Yes, in some fanfictions, Rey is considered as Anakin's reincarnation. This idea often stems from the strong connection to the Force that both characters possess. There are fanfic writers who like to explore the concept of a spiritual or karmic cycle in the Star Wars universe, and this reincarnation theory is part of that exploration.
In this fanfiction, the plot could revolve around Rey being haunted by Anakin's presence in the Force. She starts to have dreams where he shows her different scenarios of his life. As she delves deeper into these visions, she uncovers a conspiracy within the Jedi Order that was related to Anakin's downfall. Rey then uses this knowledge to reform the Jedi in the present day, all while being inspired by Anakin's complex story.
One way to write it could be by having Rey discover old holocrons about Anakin. She could be in awe of his skills as a pilot and Jedi. She might start to mimic his fighting style and try to understand his fall to the dark side and subsequent redemption. This would create an interesting dynamic as she tries to learn from his journey.
In a fanfiction where Rey meets Anakin, one possibility is that Anakin would see Rey as a symbol of hope for the future of the Jedi. He might take it upon himself to train her in the ways of the Force more deeply, sharing his own experiences both good and bad. Maybe he would guide her in how to avoid the dark side's temptations that he himself succumbed to.
One implication is that it could explain Rey's extraordinary Force abilities from the start. Anakin was a very powerful Jedi, so if Rey is his reincarnation, it makes sense she'd have such a natural aptitude.
One idea could be that Anakin's spirit somehow guides Rey in her Jedi training. Maybe he appears to her in visions and imparts his unique knowledge of the Force, especially the more unorthodox aspects he learned during his time. Another plot could involve Rey finding an ancient artifact that was once connected to Anakin, and through it, she uncovers secrets about his past that help her in her fight against the new Sith threat.
A meeting between them could lead to a unification of different Jedi teachings. Anakin was trained in the old ways of the Jedi, and Rey has her own experiences with the Force in a more modern, post - Empire context. Their meeting could result in a new Jedi philosophy. Also, it might change the political situation in the galaxy. If Anakin, with his name and history, supported Rey, it could sway many planets to side with the Resistance or a new Jedi - led movement.
In some Star Wars fanfiction, Rey might be depicted as a slave. Fanfiction often takes creative liberties and can explore different scenarios for characters. However, this is not part of the official Star Wars canon.
The meeting between Rey and Anakin can completely shift the plot. For example, if Anakin imparts some long - lost Jedi knowledge to Rey, it could give her an edge in battles or in understanding the Force better. This new knowledge might lead her to discover a hidden threat or a new way to restore the Jedi Order.
In Star Wars fanfiction, Dark Rey is a fascinating concept. It allows for a different take on the character of Rey. Writers can explore her journey to the dark side, perhaps due to feelings of abandonment or a thirst for power. It gives a chance to see how her relationships, like with Kylo Ren, would change in a darker context.
