A possible plot could be that Spyro discovers a hidden message or prophecy that indicates his mother is alive. He sets out on an adventure, facing dangerous terrains and foes. Meanwhile, his mother might be trapped in a different dimension. Spyro has to find a way to break through to that dimension. When they meet, his mother could be a very powerful dragon. She could teach Spyro about their dragon heritage and how to better control his powers for the good of their kind.
The protagonist of Naruto: The Beginning of Naruto as a Son was Naruto. He traveled to the Naruto world and became the son of Uncle Ichiraku, who adopted his mother. I hope you like this fairy's recommendation. Muah ~😗
The main antagonist might be a dark sorcerer. This sorcerer has put a spell on Spyro's mother long ago, trapping her. He doesn't want Spyro to find her because he fears that together they will be strong enough to break his power. He uses his minions to try and stop Spyro during his journey to find his mother.
Another possibility is that she was thought to be dead but actually survived. She could have her own story of survival and now she reappears in Naruto's life, bringing with her a whole new set of challenges and opportunities for Naruto.
Perhaps Naruto's brother could be a long - lost relative from a far - flung part of the ninja world. He could have been separated from Naruto when they were young due to a war or some political intrigue in the ninja clans.
At first, Naruto could be a bit skeptical. He might think it's some kind of trick or illusion. But once he realizes it's really his future self, he would be excited. He would want to know about his future family, if he has one. He'd also be interested in the state of the ninja world in the future. His reaction would be a mix of excitement, curiosity, and a determination to make sure his future turns out as good as his future self's seems to be.
In such a fanfic, Naruto might finally get to understand his family heritage better. His dad could teach him some new jutsu that only the Uzumaki family knows.
In this kind of fanfiction, Naruto might learn some family secrets from his aunt. Maybe she'll tell him about his parents' early days that he never knew before.
