Naruto's loyalty and sense of justice play important roles. He tames the dragon not just for his own gain but because he believes it's the right thing to do. If the dragon is being misused by others, Naruto's sense of justice drives him to rescue and tame it. His loyalty also means that once he tames the dragon, he will always be there for it, which in turn makes the dragon trust him more.
Naruto is very empathetic. In the fanfiction, this would mean he can understand the dragon's feelings. If the dragon is angry because it has been hurt or trapped, Naruto can sense that and respond in a kind way. His outgoing nature also makes him approach the dragon without fear, which is important in the taming process. He's not shy about showing his intentions and trying to befriend the dragon.
Naruto's outgoing personality makes him approachable as a ruler. People would feel comfortable coming to him with their problems. His determination means he won't give up on any challenges his kingdom faces. For example, if there are economic hardships, he'll keep working on solutions until they are resolved.
Naruto's outgoing personality would have a great influence on his rule. He is very friendly and approachable, so the villagers would feel comfortable approaching him with their problems. This would lead to a more connected and trusting relationship between the ruler and the ruled.
Naruto's optimistic nature would make him approach the fanfiction with an open mind. He would be more likely to find the positive aspects in it.
Since he's so open - minded, he'd likely be accepting of the strange and different concepts in the crossovers. He might even be excited to find common ground with the new characters he meets in the fanfiction. For instance, if there's a character who also has a strong sense of justice, Naruto would immediately feel a connection. His positive attitude would also mean he'd look for the good in every situation presented in the crossover fanfiction.
Anko is a bit of a wild card. Her bold and fearless personality means she might push Naruto to take risks in his training. For example, she could encourage him to face stronger opponents earlier than he might otherwise.
Her studious nature means her fanfics are likely to be very detailed. She'll pour over every little fact and make sure everything is accurate.
Since Broly has a rather wild and untamed personality, Naruto could learn to be more in touch with his primal instincts. This doesn't mean Naruto would become a brute, but rather he could find a new balance between his kind - hearted nature and a more aggressive side when necessary. For example, in negotiations or battles, Naruto could be more intimidating. Also, Broly's loyalty to his own beliefs (even if they are sometimes extreme) could inspire Naruto to be more firm in his own ninja way.
Naruto's outgoing and energetic personality would lead to bold and vibrant fashion designs. He would likely use bright colors and big patterns. For example, he might use lots of orange in his designs, just like his iconic jumpsuit.
If Percy is a confident character, he may take the pairing fanfiction in stride and even joke about it. For example, if he's the type who doesn't take himself too seriously, he might laugh it off and think it's a fun creative idea.
Ruby, being optimistic and always ready for new things, would embrace the creativity of the Undertale fanfiction wholeheartedly. Weiss, with her disciplined and somewhat traditional approach, might need some time to warm up to non - canon interpretations. Blake, who is often empathetic, would be more attuned to the emotional journeys of the characters in the fanfiction. Yang, full of vitality, would be highly entertained by the exciting and dynamic parts of the fanfiction, and her reactions would be very vocal.
