Naruto might become more confident. Having such a powerful partner like a dragon gives him an edge. He may also become more protective, as he doesn't want to lose his new friend. For example, he would be more cautious in battles to ensure the dragon's safety.
One possible plot could be that Naruto discovers the dragon in a hidden forest. The dragon, initially distrustful, eventually bonds with Naruto as they face common enemies. For example, they might fight against a powerful dark ninja clan together. Naruto could use his ninja skills and the dragon's fire or flight abilities to their advantage.
A common plotline is the dog helping Naruto with his training. Since dogs have great senses, it could assist Naruto in tracking or sensing danger during his training exercises.
A wolf would be a good choice. Wolves are known for their loyalty and teamwork, just like Naruto values his friends. It could run beside Naruto during battles, attacking enemies from the side or using its speed to scout ahead. Another option could be an eagle. An eagle could give Naruto an aerial advantage, spotting enemies from far away and swooping down to attack. It would also look really cool flying above Naruto as he moves around.
The female wolf partner could enhance Naruto's combat skills. She might be really fast and strong, and through sparring with her, Naruto becomes better at fighting. For example, she could teach Naruto some unique wolf - style combat moves.
Their partnership could introduce new combat styles. Naruto might learn from Yoshi's unique ways of moving and attacking, like how Yoshi jumps on enemies. This could add an interesting twist to his fighting techniques in battles against foes in the Naruto universe.
They might go on a journey to find a rare and powerful jutsu. Yoshi's unique abilities, like his long tongue for grabbing things or his ability to jump high, could help Naruto in tricky situations. For example, in a forest full of traps, Yoshi could use his tongue to disarm the traps from a safe distance while Naruto uses his shadow clones to scout the area.
Well, it could be a really exciting story. Naruto's energetic and determined nature would mesh well with a Digimon. Maybe his Digimon could be something like Agumon. Naruto would likely form a strong bond with it, and they'd go on adventures together, facing off against other Digimon and Naruto's usual foes in the ninja world. The Digimon could also help Naruto learn new skills or ways of thinking, just as Naruto's ninja training might influence the Digimon.
One possible storyline could be that the female wolf partner has special powers. For example, she might be able to communicate with other animals in the Naruto world, which helps Naruto in his missions. Maybe she can sense danger from afar and warns Naruto in time.
In some fanfictions, Naruto might obtain the dragon sword through a special quest. Maybe he stumbles upon an ancient temple during one of his missions where the sword is hidden as a powerful artifact, guarded by some kind of magic or traps. He overcomes these obstacles using his ninja skills and determination, and thus gets the dragon sword.
