One possible plotline could be that Naruto is banished due to false accusations of endangering the village, despite his parents being alive. His parents, Minato and Kushina, might be powerless to stop the decision because of some political intrigue within the village. Naruto then has to find his own way in the outside world, facing new enemies and making unexpected allies.
In this fanfiction concept, perhaps Naruto's unique power or some misunderstood actions lead to his banishment. With his parents alive, there could be a strong emotional tug - his parents might be torn between their loyalty to the village and their love for their son. Naruto, on his own, could start to discover hidden aspects of his heritage or abilities that the village was either unaware of or feared.
One possible reason could be that Naruto discovers some dark family secret that his parents want to keep hidden. For example, if there was a connection between the Uzumaki clan and some forbidden jutsu, and they fear Naruto might be exploited because of it. So they banish him to protect the clan's reputation and his own safety.
Well, perhaps in the fanfiction world, Naruto's parents discover some kind of 'dark power' within him that they fear might be uncontrollable. They think that banishing him is the only way to keep the village safe from this potential threat. This could be a power that is different from the Nine - Tails' chakra and seems extremely dangerous to them.
One possible plotline could be Naruto using his newfound freedom away from Konoha to search for remnants of Uzushiogakure. He might discover hidden scrolls or techniques that were once used in Uzushiogakure. Then, with his determination and the help of some friends he makes along the way, like other outcasts or those interested in the lost village, he starts to rebuild it bit by bit. Maybe he first focuses on building a small community center where people can gather and learn about the history of Uzushiogakure.
One possible storyline could be that with his parents alive, Dark Naruto might not have turned so dark in the first place. His parents' love and guidance could have steered him away from the path of darkness. For example, Minato, being a powerful ninja, could have trained Naruto properly from a young age, and Kushina could have provided the emotional support he needed. This would change the whole dynamic of the Naruto universe as we know it, and there would be no need for him to seek power in dark ways.
One possible plotline could be Naruto growing up feeling extremely lonely and trying to find ways to gain his parents' attention even though they're not around. He might start to excel in ninja training not just to prove himself to the village but also in the hope that his parents would be proud if they were there. Another could be Naruto having vivid dreams about his parents and then waking up to the harsh reality of their absence, which could fuel his determination to find out more about them and why they ignored him.
One possible storyline could be that Naruto's parents, Minato and Kushina, are alive and they train Naruto from a young age. This would make Naruto an even more powerful ninja earlier on. He would grow up with their love and support, and perhaps not be as much of an outcast in the village as he was in the original story.
One possible plotline could be that Minato and Kushina raise Naruto as a normal child in Konoha. Naruto would grow up with their love and guidance, which would significantly change his personality. He might be more confident from the start and not have that intense need to prove himself. Also, Minato could train Naruto personally, and Naruto might inherit his father's skills much earlier, leading to different adventures and battles in the ninja world.
One possible plotline could be that Naruto is caught in a powerful enemy's fire - based jutsu during a battle. Maybe the enemy has some vendetta against him and wants to see him suffer. Another could be that Naruto sacrifices himself by jumping into a burning building to save civilians. He might then struggle to survive the intense heat and his injuries.
His character development could be complex. On one hand, he might feel a sense of abandonment by the village, even though his parents are alive. This could lead to him exploring his own identity outside of being a Konoha ninja. He may develop new skills and ways of thinking as he adapts to life outside the village. His relationships with his parents could also change, as they try to bridge the gap between their son and the village.
A possible plotline is that Naruto tries to hide the abuse from his friends and the village. He is afraid of being judged or rejected if they find out. However, as time goes on, the signs of abuse become more and more obvious. His friends start to suspect something is wrong and eventually, they discover the truth. This could lead to a series of events where Naruto's friends try to help him, and Naruto has to learn to trust them and accept their help to heal from the trauma of the abuse.
