One possible plot development could be Naruto growing up in isolation, constantly feeling the sting of being abandoned. He might develop a strong sense of self - reliance and a burning desire to prove himself to his family. Maybe he starts training secretly and becomes extremely powerful on his own. Then, when his siblings finally realize their mistake, Naruto has to decide whether to forgive them or hold a grudge.
Well, Naruto is known for his positive energy. In this fanfiction, he could show his love for his siblings by bringing that positive energy into their lives. He would cheer them up when they are down, encourage them when they face difficulties. He might also cook for them or do some small but meaningful things, like helping them with their training or just listening to their problems.
His drive would be different. In the original, he wanted to be Hokage to gain the respect of the village. Here, he might aim to become Hokage to show his siblings what they missed out on. His actions would be more focused on proving himself not just to the village but specifically to his family. He would also be more self - sufficient, having had to fend for himself without the support of his siblings from the start.
One possible relationship is that of a mentor. Naruto, with all his skills and experiences, could be like a mentor to his siblings. He would teach them ninja techniques and how to face the challenges in the ninja world.
One popular storyline could be the siblings coming together to face a new, powerful enemy that threatens the Hidden Leaf Village. They might combine their unique skills, like Naruto's Rasengan and a sibling's special jutsu, to save the day.
In this fanfiction, Naruto would likely face many challenges. He'd have to provide for them, protect them from the village's possible discrimination, and also teach them ninjutsu. He might struggle to balance his own ninja duties with his new role as a caregiver.
Well, sometimes he's depicted as a fun-loving older brother. He'll play pranks with his siblings but also be there when they need him. His status as a hero in the village gives his siblings a sense of pride, and he uses that to boost their confidence. He might take them on adventures around the village, showing them all the secret spots he found when he was younger.
He might try to prove himself. Naruto has always been a determined character. So, he would likely focus on his training more, aiming to show his worth to those who neglect him. For example, he could strive to become a stronger ninja faster than his siblings, in the hope that his efforts would be noticed and the neglect would stop.
There are also fanfictions where Naruto had to fend for himself a lot, but the villagers, despite their initial hostility, would unknowingly help. For example, the local store owners might give him some food when he was really in need, even if they didn't fully embrace him. And as he grew older, his friends like Sasuke and Sakura also became important in his life and kind of took care of him in their own ways.
Sakura could be a main character. She might be the one who discovers the abandoned child and tries to figure out what to do. Kakashi could also be involved. He has a history with Naruto and might be torn between loyalty to Naruto and doing what's right for the child. Sasuke could be another character. He might return to the village and get involved in the situation, either to help or because he has his own motives regarding Naruto's actions.
