They could become resentful. They might start to avoid Naruto altogether and refuse any summons. They could also start to act out in the forest, scaring away other animals or causing minor disruptions just to show their displeasure.
The wolves could also form a pact among themselves. They decide to work on improving their own abilities without Naruto. They train rigorously in the forest, learning new hunting and fighting techniques. And they might also start to communicate with the spirits of the forest in a deeper way to gain more power and wisdom, all while hoping Naruto will one day realize what he's missing.
He could summon different types of wolves. There might be large, alpha - like wolves that are very powerful in combat. Or perhaps smaller, more agile wolves that are great for scouting. There could also be wolves with special abilities, like ones that can control ice or fire, which would add a whole new dimension to Naruto's fighting style.
He may also seek solace in his friends. Since his family is neglecting him, Naruto would likely turn to his friends like Sasuke and Sakura. They become his new 'family' in a sense, providing the support and love he doesn't get at home. He shares his feelings with them and they encourage him to keep going, which helps him deal with the pain of neglect.
He might try to prove himself. Naruto has always been a determined character. He could focus on his ninja training more intently, aiming to show everyone his worth despite being neglected. Maybe he'd also start to distance himself a bit from his family situation and form closer bonds with his friends like Sasuke and Sakura, who might understand and support him through this tough time.
Well, Naruto has always been a fighter. In this situation, he might start to explore his own unique abilities more deeply. He could go on solo missions to prove his capabilities. Also, he might look for a mentor figure other than those in his immediate family. For example, he could turn to Kakashi for more guidance and training. By doing these things, he gradually shows that he is not someone to be neglected.
He might try to prove himself. Naruto has always been a determined character. So, he would likely focus on his training more, aiming to show his worth to those who neglect him. For example, he could strive to become a stronger ninja faster than his siblings, in the hope that his efforts would be noticed and the neglect would stop.
He might focus on his training more. By pouring all his energy into getting stronger, he can distract himself from the pain of family neglect. For example, he could spend long hours practicing new jutsu or improving his physical abilities.
Naruto might try to seek attention elsewhere. He could focus on his training more intently. By pouring his energy into becoming stronger, he distracts himself from the pain of parental neglect. Also, his friends could play a crucial role. Their friendship might give him the sense of family and belonging that he lacks at home.
One interesting plot could be that the wolf summons, feeling neglected, form their own clan within the forest. They start to develop unique abilities separate from Naruto's influence. For example, they might learn to communicate with other forest animals in a more complex way to protect their territory.
He might focus on his ninja training more. By pouring his energy into becoming stronger, he can distract himself from the neglect at home. Also, he could make friends outside his family, like Sasuke or Sakura, who would provide him with the support and friendship he lacks at home.
Maybe he's been influenced by someone who has a different view of heritage. For example, if he meets a character who believes that one should create their own identity rather than relying on heritage, Naruto could be swayed. Another possibility is that he has some sort of resentment towards his heritage. Perhaps there are things in his family's past or in the traditions associated with his heritage that he doesn't agree with or is ashamed of.
