At first, Naruto would be in awe. Dragons are powerful and mysterious creatures. But then, he would quickly think about how this encounter could be beneficial. He might see the dragon as a potential friend and a source of strength. So, he would do everything he could to form a bond with it, like offering help or showing his own skills and abilities.
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.
Sasuke would be more guarded. He would see the dragon as a potential power source or a liability. He might keep his distance at first, observing how Naruto and the dragon interact. If the dragon proves useful in battles or in protecting the village, he might start to respect it more. As for Kakashi, he would be intrigued. He would likely give Naruto some advice on how to handle the situation, like how to train the dragon and keep it a secret if necessary.
Sakura might be initially shocked as killing is a serious matter, but then she would understand Naruto's reasons if she saw the cruelty of the Celestial Dragons. She would support him in the end. Kakashi, on the other hand, would probably be more analytical. He would first assess if Naruto's actions were truly necessary and if there were any other ways to deal with the situation. But once he realizes the nature of the Celestial Dragons, he would back Naruto up.
Shikamaru would be annoyed at first, thinking that Naruto has gotten them into another troublesome situation. But he would soon realize the potential benefits of having the baby dragon around, like using its abilities for strategic purposes in battles or for the overall protection of the village.
Sakura might be a bit skeptical at first. She would worry about the potential danger the dragon could pose to the village. But once she sees how Naruto is able to handle it and how the dragon is friendly, she would warm up to it. Sasuke, on the other hand, would be more interested in the dragon's power. He might see it as a tool to gain more strength, but Naruto would teach him that the dragon is a friend, not a weapon.
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.
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 village would be in shock at first. They are used to Naruto as a ninja, and suddenly he's a Dragon God. Some would be fearful, worried that he might use his new power against them. But many, especially his friends, would be proud. They would see it as Naruto reaching a new level of power to protect the village even better.
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.
Naruto would probably be very surprised. He has heard about Rin from Obito and Kakashi. So when he actually meets her, he might be at a loss for words at first.
Naruto's character would become more in tune with nature. Dragons are often seen as symbols of nature's power. By having a dragon summon, he would start to understand the delicate balance of nature better. He might also gain a new perspective on his own power and how it fits into the larger scheme of things. This could lead to him being more empathetic towards other creatures and more protective of the natural world around him.
