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 such fanfiction, Anakin often makes different choices that lead him to use his powers for good. Maybe he avoids succumbing to the dark side and instead becomes a hero.
Often, Anakin's development in these fanfictions involves him exploring different aspects of the Force. He might discover new Force abilities that were not part of the original story. This new knowledge helps him to dominate in various situations, whether it's in combat or in diplomatic negotiations. Also, his relationships with other characters, like Obi - Wan or Padmé, are often explored more deeply, which in turn shapes his character growth.
A fanfiction could explore what would happen if Anakin Skywalker had survived and joined the Rebellion during the events of Star Wars Rebels. He would bring his incredible combat skills and Jedi powers. His relationship with other characters like Hera Syndulla and Sabine Wren would be interesting to develop, as they would have to learn to trust this once - fallen hero.
Fan fiction based on this concept of a gender - swapped Anakin can vary greatly. Some might focus on how this new Anakin would interact with the other characters in the Star Wars universe. She could form different alliances or rivalries. Others might explore her journey towards the dark side. Would her reasons be the same as the male Anakin's? Or would her different gender and the way society in the Star Wars galaxy treats women play a role? It's a really fascinating area for fan creativity.
Yes, there are quite a few. You can start by looking on fanfiction websites like Archive of Our Own. Some fanfics might focus on an alternate universe where Anakin is female, exploring how that would change the Star Wars story. For example, her relationships with other characters like Obi - Wan or Padmé could be very different.
Well, the character design of a gender - bent Anakin can vary a lot. For starters, her face would be more feminine, with softer features. Her eyes might be larger or have a different color palette. In terms of her Jedi robes, they could be a different color or have different patterns. Maybe she would wear a sash or some other accessory that a male Anakin wouldn't. Also, her lightsaber hilt could be designed in a more delicate way, perhaps with some engraved symbols that are more in line with femininity.
