Jiraiya could be important. He was Naruto's mentor and knew Naruto's father well. He might have some stories about Naruto's parents that could add more depth to the meeting. Maybe he could be there to witness the encounter between Naruto and his mom and share his insights.
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 fanfiction, Naruto might finally get to know his mother's personality. He could learn about her hopes and dreams, and perhaps she would share some family secrets with him. For example, she might tell him about the Uzumaki clan's special abilities that he hadn't known before.
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.
Naruto would react with his usual enthusiasm. He'd see the succubus as someone he could potentially help or befriend. He might not fully understand what a succubus is at first, but his kind nature would lead him to approach her without fear. As for Kakashi, he'd be more guarded. He'd analyze the situation carefully before making any moves, while also keeping an eye on Naruto to make sure he doesn't get into too much trouble.
Zabuza could be quite cold to Naruto at the beginning. He's not exactly the warm - and - fuzzy type. But when Naruto shows his skills and tells his story of being banished unjustly, Zabuza might empathize on some level. He might not show it openly, but he could start to protect Naruto in his own way, perhaps because he sees a bit of his younger self in Naruto who was also wronged by the ninja system.
In some fanfictions, Naruto might use a powerful jutsu he discovers or masters. For example, he could find a forbidden jutsu that has the power to bring the dead back to life. Maybe it's a jutsu that requires a great sacrifice on his part, like giving up some of his own chakra permanently.
In some fanfictions, Naruto might find his mom through a special jutsu. For example, he could discover a hidden scroll that reveals a time - traveling jutsu. Using this jutsu, he travels back to the time when his mom was alive and meets her. Another possibility is that some powerful entity guides him to a secret dimension where his mom is trapped.
