There could be a Zabrak orphan who grew up on Coruscant. She has a natural gift for sensing danger and can move with extraordinary speed in a fight. As a second chosen one, she might be the one to bridge the gap between different species in the fight against a common enemy. Her Zabrak heritage could also give her some unique cultural insights that help in their journey.
One idea could be that the second chosen ones are a group of misfits from different planets. They discover they have latent Force abilities that are different from the traditional Jedi or Sith powers. For example, they can communicate with droids on a deeper level, influencing their programming in unique ways.
The Ones themselves are obviously main characters in such fanfics. They have their own personalities and motives that drive the story. There might also be an old and wise Jedi Master who serves as a guide to the character involved with The Ones. This Jedi Master has knowledge about The Ones from ancient Jedi lore and helps the young character understand the significance of their encounter.
In the official Star Wars lore, Anakin Skywalker is the Chosen One. However, in fanfiction, the concept can be reimagined and Obi - Wan could potentially be portrayed as the Chosen One. Fanfiction allows for creative interpretations that deviate from the established canon.
Well, in some fanfics, The Ones are involved in a power struggle within the Star Wars universe. For example, they might be at the center of a conflict between different factions vying for their power or knowledge. This can lead to epic battles and political intrigue as each side tries to use The Ones to their advantage.
One great Star Wars Fives fanfic is 'Fives' Redemption'. It delves into what could have happened if Fives had managed to expose the conspiracy fully. Another is 'Fives: The Lost Missions' which creates new adventures for Fives that were not shown in the original series. And then there's 'Fives and Echo: Reunited' that focuses on the bond between Fives and Echo and their potential further adventures together.
In some fanfictions, the Chosen One is actually a character that was overlooked in the original story. Maybe a background character who discovers they have the potential to be the Chosen One. This could involve a lot of self - discovery and dealing with the disbelief of those around them. They would have to prove themselves against the odds and rewrite what it means to be the Chosen One in the Star Wars universe.
Some great Rex and Cody fanfics focus on their brotherly bond. For example, 'The Adventures of Rex and Cody' which shows them facing challenges together on the battlefield. It really captures their loyalty to each other and to the Republic.
There are also fanfics that look at the perspective of other characters when Anakin is injured. For instance, Obi - Wan might be deeply concerned and try his best to support Anakin. These fanfics can give a new understanding of the bond between them. And some might feature Anakin's clones, who are loyal to him and do their best to protect their injured general.
