Padmé could be a key character. She loves Anakin deeply and might be in a position to somehow prevent the situation that would lead to his burning. Maybe she uses her diplomatic skills or some inside knowledge to stop the events from unfolding in a way that would harm Anakin.
It could be a new character introduced specifically for this fanfic. This character could have some unique abilities or knowledge. For example, a mysterious Jedi from a far - flung planet who has mastered a form of Force - based protection against heat. This new character could befriend Anakin and be there at the crucial moment to stop him from getting burned.
Perhaps in this fanfic, Anakin has developed some sort of new power or ability that protects him from getting burned. It could be related to his connection with the Force. He might have found a way to manipulate the Force in such a way that it forms a protective shield around him when the threat of burning is imminent. This new power could be a result of his continuous exploration and growth in the Force.
In addition to Anakin, Padmé, and Obi - Wan, the Jedi Council members could be significant characters. They might interact with Anakin in new ways, perhaps being more accepting of his unorthodox methods as he doesn't go down the dark path. Also, characters like Yoda could play a role in guiding Anakin further in the light side of the Force.
In some fanfics, it could be Anakin's own self - destructive tendencies. He has made so many bad choices in his life that in the end, his own actions lead to his death. For example, if he continues to pursue the dark side without fully understanding its consequences, it could ultimately consume him and lead to his demise.
Anakin's mother, Shmi, would likely be a very important character. Since Anakin is not being trained as a Jedi, he would be more focused on his family. Shmi's influence on Anakin would be even greater, and she could play a role in guiding his actions and decisions, especially in relation to the local community on Tatooine.
Well, it could be a fanfic that explores an alternate universe where Anakin Skywalker doesn't turn to the Dark Side. Maybe it focuses on how his relationships would be different, like with Padmé, Obi - Wan, and the Jedi Order. It could also show how the events of the Star Wars universe would unfold without the fall of Anakin.
Anakin might become more withdrawn. The pain from the burns could make him more introspective and less likely to engage in his usual activities.
His mother, Shmi, would definitely be a main character. She could play an even more important role in Anakin's life, guiding him in using his abilities for the good of Tatooine. Also, Watto, the junk dealer, could be a significant character. Their relationship might evolve from one of slave - owner and slave to something more complex, like a grudging friendship or a business partnership as Anakin grows older and more skilled.
There could be a hermit or an outcast Jedi or Sith on Dathomir. Anakin meeting this character could lead to a great revelation. Maybe this character has been in hiding on Dathomir for years, observing the balance of the Force there, and Anakin's arrival disrupts that balance and forces an interaction that changes Anakin's perspective on many things.
He could interact with Luke Skywalker. Imagine Anakin finally getting to meet his son as an ally in the Rebellion. They could train together and share their knowledge of the Force.
Padmé Amidala could be involved. As Anakin's love interest, she might discover his ticklish feet during a private moment between them. It could be a cute and intimate moment that shows their relationship in a more playful light.
