He could have a summon - like animal as a pet. For example, a toad that he befriends and keeps as a pet instead of just using for summons in battles.
A talking squirrel could be his pet in fanfiction. It could be a source of comic relief, always chattering away and getting into little mischiefs while also being able to give Naruto some valuable advice in its own cute, squirrel - like way. This would add a different kind of charm to the fanfiction.
He might still have his enhanced physical abilities. Even as a pet, Naruto could be super strong and fast. This would be useful for Ruby in a lot of ways. For instance, if they were in a dangerous situation, Naruto could use his speed to escape or his strength to protect Ruby.
Well, Naruto could be in awe of Beerus' power. Maybe he tries to learn some of Beerus' combat techniques. Since Naruto is known for his determination, he might pester Beerus to train him.
Well, in the fanfiction, it's possible that one of the sisters has a power related to the wind, just like Naruto. But instead of using it for offensive attacks mainly, she uses it for more defensive and utility purposes, like creating wind barriers or using the wind to carry messages. Another sister could possess a fire - based power. She could be a master of fire jutsu, creating intense flames that can melt metals. The third sister might have a unique power of light, being able to blind enemies or use light to create illusions.
In this fanfiction, Naruto could possess the power of regeneration. Dragons are often depicted as having strong regenerative abilities. So, if Naruto gets injured in battle, he might be able to heal himself much faster than before. Additionally, he could have the ability to sense things from a great distance, like a dragon can detect prey or danger from afar. His senses of sight, smell, and hearing could be greatly enhanced, allowing him to be more aware of his surroundings and better anticipate attacks.
It could be a snake that has the ability to communicate with Naruto telepathically. This snake might be a rare species from a hidden forest in the Naruto world. It could have markings on its body that are related to some ancient prophecy. The snake's intelligence and unique abilities would make it a very special pet for Naruto in the fanfiction.
One possibility is that the child has a unique form of sensory perception. Naruto has his own way of sensing things, and Koyuki might have some hidden senses related to her royal heritage. Combined, the child could have a super - sense that allows it to detect not only chakra but also other hidden energies or threats. Also, the child could have the ability to communicate with animals, a trait that could come from Naruto's connection to the toads and Koyuki's possible connection to the local fauna in her land.
He could go on adventures to find lost fox clans. The foxes might ask for his help to locate their missing members or to protect their territory from other threats. Naruto, with his ninja skills and ability to talk to foxes, would be well - equipped for such quests.
Perhaps he would be a fan of traditional Japanese music. Given his strong connection to his ninja village and Japanese culture in general, it could be a way for him to connect with his roots on a deeper level. In this fanfiction, he could be shown exploring the different instruments like the shamisen or the koto, and the various melodies that have been passed down through generations.
They could go on a mission to track down remaining threats from the war. There might be rogue ninjas or hidden enemy bases. Naruto's combat skills and Temari's strategic mind would make them a great team.
They might go on a journey to discover a hidden ninja technique. For example, Naruto and Sasuke could set out to find a long - lost jutsu that was once used by a powerful ninja in the past. Along the way, they face various challenges like traps set by other ninja clans who don't want them to succeed.
