Bulma would be excited to study Naruto's abilities. She would be constantly asking him questions about his chakra and his ninja techniques. She might even try to find a way to incorporate some of his technology into her inventions. Android 18 might be indifferent at first, but if Naruto shows his courage in battle, she might start to like him. As for Naruto himself, he would be in awe of the power levels in the Dragon Ball universe. He would be both intimidated and motivated to become stronger, especially after being neglected in his own world. He would look up to Goku as a role model and strive to be like him in terms of strength and character.
The Z - fighters like Krillin and Yamcha would be curious about Naruto. Krillin might try to befriend him quickly, while Yamcha might be a bit jealous if Naruto starts getting a lot of attention. In the Naruto world, characters like Sakura and Sasuke might not even notice Naruto's disappearance at first if he has been neglected. But later, they might realize the importance of Naruto when things start to go wrong in their world without him. And in the Dragon Ball universe, Piccolo would be very watchful of Naruto, trying to figure out his motives and if he poses any threat to the safety of the planet.
The Kumo ninja would likely be angry at first. They'd feel that Naruto, as a symbol of hope in the shinobi world, should have noticed their problems. But some of them might also be hopeful that Naruto's arrival would finally change things for the better. As for Naruto himself, he'd probably be shocked to realize how much he'd overlooked Kumo and would feel a sense of guilt.
At first, Naruto would likely be very curious. He'd be eager to learn about this new world of Dragon Ball Z through the fanfiction. As he delved deeper, he'd start to form his own opinions about the characters. He might admire Goku's pure heart and his never - ending quest for self - improvement, and perhaps think about how he can apply some of those qualities to his own life as a ninja.
The reaction of the Dragon Ball characters to Thanatos' invasion would be complex. Goku, as always, would approach it with a sense of adventure and the desire to test his limits. He would be the first to reach out to Thanatos in combat. Vegeta would be seething with anger at the thought of someone invading their territory. He would fight with all his might, using his Galick Gun and other powerful attacks. For the younger characters like Trunks and Goten, they would be inspired by the older fighters. They would follow their lead and contribute in their own ways. The non - Saiyan characters like Krillin and Tien would use their unique fighting styles and skills. The Dragon Ball universe has a long history of coming together against threats, and this would be no different.
Perhaps in this fanfiction, Naruto is neglected because of a prophecy that foretells of his great power which scares the people in his village. He then stumbles upon a way to enter the Dragon Ball universe. In this new universe, he meets Bulma who is intrigued by his strange powers. With her help, he tries to find a way to either go back to his world and prove his worth or make a new life in the Dragon Ball universe. Along the way, he gets into battles with the likes of Frieza when the tyrant tries to take over a planet that Naruto has come to care about.
Naruto would first be cautious, but then his friendly nature would take over. He'd try to find common ground with the dragon. Since he has a connection with all living things, he'd attempt to communicate with it on a deeper level. He might share his dreams and stories with the dragon, hoping to gain its trust.
Gohan would likely be extremely shocked and angry. He is Pan's father and would have a hard time accepting this situation. Vegeta might be disappointed in Trunks, as it goes against Saiyan propriety. Bulma would probably be worried about the implications for the family and how to handle the situation. Goten might be confused and not know how to react, as it involves his nephew and niece in a very unexpected way.
One possible plot could be that in a world where Naruto characters co - exist with Dragon Ball Z characters, Naruto is so focused on his own ninja world problems that he completely overlooks the power and significance of the Dragon Balls. For example, villains from the Naruto world might accidentally stumble upon the Dragon Balls and try to use them without understanding their true power. Meanwhile, Goku and his friends are trying to retrieve the balls from this new, unaware threat.
Rarity would be more interested in how the power levels are presented visually. If there are any shiny or impressive displays of power, she would be all about it. Pinkie Pie would just turn it into a game, making up her own power levels for the Mane 6 and seeing how they stack up against the Dragon Ball characters. Applejack would think the power levels are a bit over - the - top but would respect the fact that it's part of the Dragon Ball world.
Some characters may laugh out loud. The abridged fanfiction often has comical elements that could make the characters find it really funny.
It could be Orochimaru. In this fanfiction, Orochimaru might hear rumors about the Dragon Balls and their power to grant wishes. Since he is always seeking power and immortality, he decides to hunt for the Dragon Balls. However, because Naruto is so focused on his own battles against Orochimaru in the ninja world, he fails to realize that Orochimaru's new goal involves the Dragon Balls and the entire Dragon Ball Z universe could be at risk.
