Obi - Wan Kenobi is frequently re - written as well. He could be portrayed as more of a maverick Jedi, willing to break some of the Jedi Council's rules to do what he believes is right, or having a different approach to training Anakin that might have averted the dark side allure.
Rey is also a central figure. Her origin story could be rewritten in different ways. Some fanfictions might explore the idea that she has a more direct connection to the Skywalker family or other important Star Wars lineages, rather than the somewhat ambiguous origin in the original TLJ.
One interesting idea could be a rewrite where Anakin is trained more thoroughly in the ways of the Jedi, which might prevent his fall to the dark side. For example, if the Jedi Council had been more open - minded about his relationship with Padmé and worked with him to manage his emotions, things could have been different.
Well, Rey is a popular character who could be involved. She could be twinned with another Force - sensitive character, maybe someone from a different part of the galaxy. Finn is also a possibility. He could be twinned with a character who shares his sense of loyalty and his journey of self - discovery. Kylo Ren, with his conflicted nature, could be twinned with a character that represents the opposite side of his internal struggle. This would create a great opportunity to explore his character in more depth through the twinning concept in fanfiction.
Leia Organa is often included. She's a strong and iconic character. Her leadership and beauty make her a natural choice. Padmé Amidala is also popular. Her grace and political acumen add depth to the harem - like scenarios. And of course, Ahsoka Tano. Her skills as a Jedi and her independent spirit are appealing in these types of fanfictions.
Darth Vader is sometimes used in an interesting way in these fanfictions. Even though he's a symbol of the dark side, some fanfictions might explore a sort of unrequited love or a complex relationship where someone in the Empire has feelings for him, perhaps seeing the conflict within him that others don't. It adds a dark and complex layer to the romance.
In Star Wars animal transformation fanfiction, Yoda is a character that is often included. His deep understanding of the Force could play a crucial role when dealing with a transformed animal. Padmé Amidala could also be involved. She might use her diplomatic skills to handle situations involving transformed animals. Additionally, Obi - Wan Kenobi, with his wisdom, could guide others in understanding the significance of an animal's transformation.
Qui - Gon Jinn is often a popular character in these fan fictions. His maverick ways within the Jedi Order make him an interesting subject for alternate storylines. Writers might explore what would have happened if he had survived longer and continued to mentor Obi - Wan and Anakin.
Luke Skywalker is often a popular character. His journey from a simple farm boy to a powerful Jedi knight makes him a prime focus. Also, Darth Vader, with his complex backstory and his struggle between the light and dark, is frequently featured.
Luke Skywalker is also commonly featured. As the hero of the original trilogy, his journey and growth in the Force make for interesting battles, whether he's facing off against Sith or other threats in the fanfiction Death Battle settings.
I'm not entirely sure without reading it, but it's likely to include some new characters who are important in Star Wars 7. There may also be some cameos or references to classic Star Wars characters to tie it to the overall saga.
