The key characters in a 'Son of Sons' Star Wars fanfiction could be the protagonist who is the 'Son of Sons' himself. He might be in conflict with the remnants of the Empire or a new dark side threat. There could also be a mentor figure, perhaps an old Jedi who survived Order 66 and now guides the young 'Son of Sons' in his journey. Another character could be a rival, someone who is jealous of the protagonist's lineage and the potential power it brings.
Often, in such fanfictions, the 'Son of Sons' is a central character. There could be his family members as well. His mother or father might have left behind secrets or a legacy that he has to uncover. And then there are the antagonists. It could be a Sith cult that wants to either corrupt the 'Son of Sons' or eliminate him to prevent him from fulfilling a prophecy that could bring an end to their dark plans.
One common plotline is the discovery of the protagonist's heritage. The 'Son of Sons' might start as an ordinary person in the Star Wars universe, like a simple farmer on a remote planet. But then he discovers that he has a special lineage. This leads to a journey of self - discovery as he tries to understand what it means to be the 'Son of Sons' and the power and responsibility that comes with it.
Since I haven't read this particular fanfiction, I can't say for sure. But it could be the'son of suns' character as the main protagonist, and perhaps some classic Star Wars characters like Jedi knights or Sith lords who interact with him.
In this fanfiction, General Grievous would be a key character. His combat skills and experience leading the droid armies are invaluable. Also, there might be some new characters created specifically for this scenario. For example, a droid engineer who comes up with new ways to upgrade the droids to fight the Empire's advanced technology. And of course, if there are any surviving Separatist leaders, they would be important in leading the fight.
The exiled character is obviously a key one. Their actions and decisions drive the story forward. There may also be a mentor - like figure who helps the exiled character in their journey, either physically or through memories or visions.
Obviously, Darth Vader is the key character. He is the central figure around which the story revolves. His actions, decisions, and internal struggles drive the narrative.
Darth Vader is a key character. His menacing presence and his role as the Emperor's enforcer are central to the story. He is a symbol of the Empire's power and ruthlessness.
Obviously, the son of Abeloth would be a main character. There might also be some Jedi or Sith characters who interact with him.
The Son of Abeloth is the central figure. Alongside him, there could be an old and wise Jedi Master who senses the potential in the Son of Abeloth, either for great good or great evil. There might also be a Sith apprentice who sees the Son of Abeloth as a threat or a tool for his own rise to power. And don't forget about the smugglers or bounty hunters who might get caught up in the events surrounding the Son of Abeloth, either by accident or for a hefty reward.
The main character is Darth Maul. There are also likely other characters from the Star Wars universe who interact with him, such as Jedi or other Sith, but Darth Maul is the central focus.
Kylo Ren is a key character. He is a powerful Force - user in the First Order, with a complex personality. General Hux is also important, as he is a high - ranking military official in the First Order.
