During his travels, Naruto experiences a great deal of growth. He starts to question his own beliefs and values. For example, in a dimension where the concept of good and evil is completely different from what he knows, he has to reevaluate what he considers right and wrong. His leadership skills also improve. When he encounters groups of people in different dimensions, he often has to take charge to survive or to achieve a common goal. This makes him more confident in his ability to lead. Moreover, his relationship with his own powers changes. He realizes that the Rinnegan is not just a tool for combat but also a key to understanding different worlds and cultures.
Naruto's character develops in many ways. Firstly, he becomes more adaptable as he faces different situations in each dimension. He has to quickly figure out the rules and powers in each new place. Secondly, his understanding of power grows. In some dimensions, his Rinnegan - based abilities might be limited, so he has to rely on his wits and other skills, which makes him more well - rounded. Thirdly, his sense of empathy deepens. Meeting different beings in various dimensions, some of whom might be suffering, makes him more determined to protect and help those in need, just like he does in his own world.
Naruto's character development during these travels is multi - faceted. His worldviews expand significantly. He gets to see different forms of society, from utopian to dystopian dimensions. This broadens his perspective on how a world can be organized. His mental strength increases as he has to deal with isolation in some dimensions. Being away from his friends and the familiar environment of the Hidden Leaf, he learns to rely on himself more. He also becomes more diplomatic. In dimensions where there are conflicts between different groups, he tries to find peaceful solutions instead of just fighting. All these changes shape him into a more mature and complex character compared to the Naruto we know from the original series.
