There could also be a Sith Lord as a main character. A Sith, by nature, often has a great deal of pride in their power. This Sith Lord could be on a quest to prove their superiority not only to the Jedi but also among other Sith, and their pride could be their most defining and also most dangerous trait.
I think Kakashi could be a main character too. As Naruto's mentor, he would play a crucial role in trying to guide Naruto away from the negative effects of pride. Also, Sakura might be in the story, perhaps she notices Naruto's prideful behavior and tries to help him in her own way.
Another storyline could involve a young padawan who is taught by a prideful master. The padawan has to struggle between following the teachings of a master who is often wrong due to pride and finding their own path. This could lead to a journey of self - discovery for the padawan and a potential break from the traditional Jedi teachings.
Harry Potter himself is often a main character in these fanfictions. His journey to fight against the forces of pride is a common theme. Since he is the hero of the original series, it makes sense that he would be central in exploring how pride can be a sin. For example, his growing fame could lead to a sense of pride that he has to overcome.
Perhaps the main characters are a group of young Jedi apprentices who have to survive in a 'shattered' Star Wars universe. They might be led by an older, more experienced Jedi who is trying to teach them how to adapt to the new and dangerous situation. There could also be some Sith or dark side characters who are causing more chaos and are the main antagonists for these young Jedi.
I'm not certain, but it might feature a character who has some connection to the shadows, like a Force - user who can manipulate shadows. There could also be an ordinary person who gets caught up in events related to this shadowy aspect of the story.
Well, Archer himself is obviously a main character. He could be a new character inserted into the Star Wars universe. And often, characters like Luke Skywalker or Princess Leia might also be main characters. They could interact with Archer, for example, Luke might be intrigued by Archer's different fighting style and try to incorporate some of it into his Jedi training.
The main characters are typically the rookie Clone Troopers. They are new to the war and still learning the ropes.
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.
Since I haven't read 'sin and punishment star successor story', I can't say for sure who the main characters are. But typically, in a story with such a title, there might be a central character who is the 'star successor' and perhaps some characters who represent the 'sin' or are involved in the 'punishment' aspect.
Often, in 'Star Wars Operation Knightfall Fanfiction', the main characters can include Emperor Palpatine as he is the mastermind behind the operation. Some fanfictions may focus on Anakin Skywalker's transformation into Darth Vader during this time, so he would be a central character. There could also be Jedi Masters and Knights who are trying to resist the Sith's plot. For instance, characters like Obi - Wan Kenobi might be included, as he was one of the few Jedi who survived the initial purge and could be a key figure in a story about the events of Operation Knightfall.
