In a fanfiction where Boruto meets Kid Naruto, there could be a lot of chaos at first. Boruto might be shocked to see a younger version of his father. Kid Naruto would probably be curious about Boruto's strange clothes and gadgets. They could end up getting into some kind of adventure together, like facing a common enemy. Maybe Boruto would show Kid Naruto some of his ninja techniques from the future, and Kid Naruto would teach Boruto some of his own unique skills that he developed during his own time as a young ninja.
Well, if Boruto meets Kid Naruto in a fanfiction, it could be really interesting. Boruto might initially look down on Kid Naruto because he seems so unrefined compared to the Hokage his father becomes. But as they interact, Boruto would start to understand the determination and spirit that made his father who he is. They could have a friendly spar, and Boruto would realize that Kid Naruto is no pushover. Kid Naruto, on the other hand, would be amazed by Boruto's advanced technology and different ninja style.
If Boruto meets Kid Naruto in a fanfiction, it would be a meeting of two very different generations of ninjas. Boruto comes from a more advanced and somewhat jaded world compared to Kid Naruto's simple yet full - of - heart world. Boruto could try to give Kid Naruto advice on how to become a great ninja faster, but Kid Naruto would probably ignore it and stick to his own way of doing things. They might also bond over their shared love for ramen. And perhaps, together they could face a threat that requires both Boruto's future knowledge and Kid Naruto's raw talent and guts.
