Anakin might develop more self - control earlier. Yoda's wisdom and unique training style could help him better understand his emotions and not be so easily swayed by fear, which was a major factor in his fall to the dark side in the original story.
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.
The arm could also be a source of power in fanfiction. Writers could imagine that the arm has some hidden abilities or upgrades that Anakin discovers over time. This can add an element of surprise and make Anakin an even more formidable force in the Clone Wars setting.
Anakin and Padme's love story began with a simple attraction. Anakin was drawn to Padme's beauty and intelligence. Padme, in turn, saw the good in Anakin despite his flaws. Their love grew as they faced various challenges together. But Anakin's insecurities and the pull of the dark side led to his downfall. This ultimately led to the end of their relationship in a very sad way, with Padme losing hope and Anakin losing his way.
Anakin's tale is heart-wrenching because of the series of unfortunate events and choices. He was tormented by fear and visions, which drove him down a destructive path. Also, his relationships suffered greatly, adding to the sadness of his story.
Anakin could encounter future versions of his friends or enemies from the past. For instance, he could run into a future version of Obi - Wan Kenobi who has also somehow traveled to that future time. Or perhaps he meets a new generation of Sith who have different motives and methods compared to the Sith he knew in his own time. They could challenge his understanding of the dark side and the Force in general.
The SI could also be a love interest for Anakin. In a fanfiction, this could be a very different kind of relationship compared to what he had with Padmé. This relationship could either be a positive influence, giving Anakin more stability and a reason to stay on the light side, or it could be a source of conflict, especially if the SI has their own secrets or agendas.
The Hutts would likely oppose Anakin. They have long held power on Tatooine through illegal and immoral means, and Anakin's takeover would threaten their control over the planet's criminal underworld and trade routes.
It could be a new and powerful dark side user. This character might have emerged from the shadows, having trained in secret, and their sole purpose is to take down Anakin as he is seen as a threat to their plans for galactic domination.
