There could be a group of diverse characters. For example, a pilot who is an excellent flyer but has a bit of a rebel attitude. And a mechanic who is crucial for keeping the ships in working order. They all come together to form the core of the rebellion story.
R2 - D2 and C - 3PO are very likely to be main characters as they are the most iconic droids in the 'Star Wars' franchise.
Obviously, Kenobi himself will be the main character. And Darth Vader is very likely to be a major character too, considering their intertwined fates.
A clone trooper named Rex could be a main character. He's already shown some signs of independent thinking in the official Star Wars lore. Another could be a Jedi who is sympathetic to the clones' cause, like Ahsoka Tano. She has a close relationship with the clones and might be more likely to side with them if they were to rebel. And a third character could be a new clone who has a unique genetic mutation that gives him enhanced abilities and a stronger will to fight for freedom.
For main characters in a 'Star Wars Droid Rebellion' fanfiction, there could be a group of droids. Firstly, an old medical droid that has seen too many droids being deactivated without proper care. It decides to use its knowledge of droid anatomy to help the rebels. Then there's a security droid that has been reprogrammed by accident to have emotions. This security droid uses its combat skills to protect the other rebels. And finally, a droid engineer who creates new weapons and defenses for the droid rebellion, using its skills to turn the odds in the droids' favor.
Obviously, Obi - Wan Kenobi himself will be the central character. There's also a high chance of Darth Vader making an appearance since their relationship is a crucial part of the Star Wars saga.
Luke Skywalker is definitely important. His journey as a Jedi in training and his role in the Rebellion is central.
There could be smugglers like Han Solo was in the original Star Wars. They often operate in the shadows, doing deals that are not exactly legal. Another likely character type could be bounty hunters. They work in the fringes of society, chasing after targets for money.
In a lot of these fanfictions, Luke Skywalker is often a favorite. He's such a central figure in the Star Wars universe and in the context of the Jedi Rebellion, he represents hope and the revival of the Jedi Order.
In 'Star Wars Solo: A Star Wars Story', the primary characters are Han Solo, a young and ambitious man looking to make his mark in the galaxy. Chewbacca, the big and furry Wookiee, who becomes Han's close friend and ally. And Lando Calrissian, a smooth - talking and stylish character who owns the Millennium Falcon at first. These characters interact in various ways, driving the story forward with their different personalities and goals.
In the 'Star Wars The Last Jedi Rewrite Fanfic', the main characters will probably include Rey, the strong - willed and powerful Force - user. Kylo Ren, with his complex personality and his ties to the dark side. Luke Skywalker, as his presence is essential to the Star Wars lore. Finn, who is trying to find his identity and purpose outside of the First Order. And Poe Dameron, the fearless pilot who is always ready to take on challenges for the Resistance.
