Naruto's confidence would grow exponentially. Having the power to stop time gives him an edge in almost every situation. This new - found confidence could make him bolder in his actions and decisions. He might start to challenge the traditional ways of the ninja world more. He could also use this power to better understand his own emotions. In the stillness of the stopped time, he can really dig deep into his feelings of love for Hinata, his friendship with his comrades, and his sense of duty to the village.
He would likely become more responsible. Since he has such a powerful ability, he knows he has to use it for the good of the village. He may start to take on more leadership roles, as he can now analyze situations more thoroughly in the frozen time. He'll also become more empathetic as he can use the time - stopping to understand his friends' and enemies' situations better. For instance, he could stop time to study an enemy's past and find out what made them the way they are, and then try to help them instead of just fighting.

At first, Naruto might be overconfident with his reality - controlling power. He'd probably use it without thinking, like getting instant ramen whenever he wants.

Often, Naruto in these fanfictions will have to face the consequences of his power hunger. He may lose the trust of his friends initially, which could then lead to a realization that power isn't everything. His development could then take a turn where he tries to regain what he has lost while still holding onto his new - found strength in a more balanced way.
In this fanfiction, Naruto's power development could also be related to his perception of the world. Aizen's own view of power and the world is very different from what Naruto has been exposed to. Through their interactions, Naruto might start to see things from a different angle. This change in perspective could lead to a growth in his power as he discovers new ways to use his abilities. For instance, he could start to understand the weaknesses in his opponents more clearly and use his powers in a more targeted and effective manner.
In many time travel fanfictions, Naruto's character develops a deeper understanding of the ninja world. When he travels back in time, he sees the events and people that shaped his present world.

His character might also become more empathetic. As he glares at Sirzechs' power, he could start to understand the responsibilities that come with great power.

This could lead to a more well - rounded Naruto who not only has physical strength but also emotional intelligence.

For instance, he can give more empathetic advice to Sasuke about his family and clan issues. He also might be able to form new alliances with characters he previously had no connection with because of his new - found mental acuity.
Naruto's character may develop a more nuanced view of the world. Being in the Akatsuki, he sees the other side of the shinobi world that he didn't fully understand before. He might become more cautious and calculating, as the Akatsuki is full of dangerous individuals.
