Besides Naruto, there might be a young girl named Hana. She could be from a family that was once friends with Naruto's family but now has mixed feelings about him. She's conflicted between her family's stance and her own sense of justice. And then there's Kenji, a strong - willed boy who was also shunned in a different way and he and Naruto form a bond based on their shared experiences.
It could be a family member who has a personal vendetta against Naruto and is the main instigator of his being shunned. Maybe an older cousin who is jealous of Naruto's potential.
Their children could be main characters. For example, if they have a son, he could inherit Naruto's determination and Samui's calmness. He might struggle with living up to his father's reputation while also trying to carve out his own identity in the ninja world.
Bulbasaur - girl might be a great choice too. Her connection with nature and plant - based attacks could add an interesting dynamic. She could help Naruto understand the Pokemon world better, especially when it comes to things like finding herbs or dealing with forest - related challenges. There could also be a fiery - tempered Charmander - girl who provides a contrast to Naruto's more easy - going nature and has her own set of powerful fire - type attacks.
Well, it could be that Naruto is shunned by his family because of some false accusations or misunderstandings. In the fanfiction, he might then go on a journey to discover the truth behind his family's actions. Along the way, he could encounter other outcasts who he bonds with and together they form a sort of 'family' of misfits.
Obviously, the Jedi who adopt Naruto would be main characters. For example, a Jedi Master like Obi - Wan Kenobi could be the one to discover Naruto and take him under his wing. Another could be Yoda, who would be very interested in Naruto's unique abilities and would play a role in his training. There could also be other young Jedi trainees who become Naruto's friends or rivals during his time at the Jedi temple.
Sasuke could be one of the main characters. He might initially be skeptical about Naruto's new identity but then come to accept it and fight alongside him. Sakura could also be there, perhaps using her medical skills to help Naruto when he gets injured during his adventures related to his Pegasus heritage.
One of the main characters could be Fleur Delacour. Since she's from Beauxbatons, she might be the one to first interact with Naruto. She could be curious about his strange abilities and help him adjust to the school. Another could be a male student at Beauxbatons who is initially jealous of Naruto getting all the attention but later becomes his friend after seeing his true character.
There could be a leader of the horde. This character might be initially skeptical of Naruto but later comes to respect him. Another character could be a young member of the horde who looks up to Naruto as a role model and wants to learn from him.
Maybe there are new characters created specifically for this fanfiction. They could be local inhabitants of the wet area, such as a water nymph - like character who has knowledge about the secrets of the place and either helps or hinders Naruto's journey.
Lelouch could be a main character. Since he is a key figure in the Code Geass world which has Britannia. He and Naruto might start as rivals due to their different approaches to justice but later become allies. Suzaku could also be involved. He might be initially suspicious of Naruto but come to respect him as Naruto shows his good intentions in the Britannian world.
