There could be a young and inexperienced character who discovers they have some special ability related to hyperspace. This character then gets caught up in the great hyperspace wars and has to learn quickly to survive and make a difference. There might also be some veteran warriors who have seen many battles in hyperspace and act as mentors or antagonists depending on their motives.
Maybe there are some alien species leaders as main characters. They could be leading their respective races in the hyperspace wars, with their own unique personalities and goals. For example, one could be a wise and diplomatic leader trying to find a peaceful solution, while another might be a war - hungry brute only interested in conquest.
It could be about a fictional war that takes place in hyperspace. Maybe it involves different species or factions fighting for control over valuable resources or territory in this hyperspace realm.
Luke Skywalker is one of the main characters. His journey and growth as a Jedi are often central to the stories.
Smugglers like Han Solo - type characters might be main characters too. Their adventures in hyperspace, whether it's evading the authorities or finding valuable cargo, can be the focus of the stories.
Ahsoka Tano would be a great character to include. She's strong - willed and has a unique connection to the Force. Her presence on Mortis could bring new perspectives and her skills as a fighter would be useful in the challenges there.
The chase scenes in hyperspace are really exciting. The ships zipping through different dimensions at incredible speeds make for great action.
The main characters are typically the rookie Clone Troopers. They are new to the war and still learning the ropes.
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.
I'm not sure specifically as it's a fanfiction, but there could be a fearless captain leading his crew into battle.
Obviously, Naruto is one of the main characters. He is usually at the center of the story, using his skills and determination to navigate the clan wars. Sasuke is also often a main character, as his past and connection to the Uchiha clan play a big role. Sakura might be there too, using her medical ninjutsu to help those injured in the wars. And then there are the clan leaders, like the Nara clan leader or the Hyuga clan leader, who have their own agendas and power dynamics within the story.
