A young inventor could be a main character. He is full of new ideas and is trying to make Star City a better place with his inventions.
A young and ambitious sand ninja named Kaito could be a great main character. He's eager to prove himself and rise through the ranks in Sunagakure. Another could be a female ninja, Saya, who has a special jutsu related to sand manipulation that sets her apart.

Red could be a great main character. He's one of the most iconic Pokemon trainers. You could tell the story of his journey from a different perspective, like how he got his first Pokemon and what his real motivations were at the start of his adventure.
Tom, Star's ex - boyfriend, could also be an important character. His presence could create some tension in the story. He might still have feelings for Star and try to win her back, which would complicate Star's budding relationship with Marco. Additionally, characters like Janna could be added. Janna is known for her mischievous nature and she could play a role in either helping or hindering Star's relationship with Marco, perhaps by uncovering secrets or playing pranks that have an impact on their relationship.
A species - specific character like a Chiss bounty hunter. The Chiss are known for their intelligence and strategic thinking. This bounty hunter could be on a mission to capture a high - profile target in the Star Wars Visions universe. They would use their unique Chiss abilities, such as their natural aptitude for tactics, to outwit their opponents.
Maybe a smuggler. Smugglers have always been an interesting part of the Star Wars universe. They often get caught up in bigger events and have their own set of skills and motives. So a new smuggler character could be a main character in the new story.

One potential main character could be a young Iburi Clan member who is just starting to come into their powers. They would be full of enthusiasm and curiosity about their clan's abilities.

And then there could be a half - Iburi Clan character, who struggles with fitting in both the Iburi Clan world and the world of their other heritage.
Boruto, Naruto's son, is an obvious choice. He already has his own story in the Boruto series, but in a fanfic, you can take his character in new directions. Himawari, Boruto's sister, could also be a main character. She has the potential for great power and a unique personality.
