How would Naruto's personality be affected if Asura Otsutsuki entered his mindscape in Naruto fanfiction?

One possibility is that Asura Otsutsuki could impart some ancient knowledge or power to Naruto. Maybe he reveals secrets about the Otsutsuki clan that could help Naruto in his battles or in understanding the world better.

He might interact with Naruto himself. Ashura could act as a mentor, guiding Naruto on how to better control his own chakra. Since Naruto has the power of the Nine - Tails, Ashura could show him ways to merge his own chakra with the Nine - Tails' chakra more effectively, enhancing Naruto's power.

His core Naruto - like personality of being determined and never - giving - up would still be there. But he might become more refined and elegant like the elves. He would probably have more patience due to the elven influence. His boisterousness might be toned down a bit, but he would still be the energetic Naruto at heart, just with a more elven - like exterior in terms of behavior.

Naruto might become more secretive. Growing up in the Snake Clan, which is often associated with secrecy and hidden motives, he could pick up on their ways of not revealing too much about himself or his plans. For instance, instead of being as open and brash as in the original series, he would be more guarded in his conversations.

Naruto's personality might become more calm and centered. Yoda could teach him to control his impulsiveness. So instead of rushing into things, he'd think more before acting.

Naruto would likely be very conflicted. He is a person who values family deeply, so fighting his sister would go against his nature. This could make him seem more hesitant in the fight, constantly looking for a way to end it without hurting her too much.

In this fanfiction, perhaps Ashura Otsutsuki in the mindscape is trying to convey a message about an upcoming threat to the Naruto world. He could be guiding the protagonist to gather certain artifacts or allies to face this threat. For example, he might lead the character to an ancient temple where a powerful weapon lies, which is crucial to defeat the new enemy.

Naruto's personality could change in several ways. He has always been determined, but now with the magma - related powers, he might become more assertive. He could also be more protective, seeing his new powers as a way to safeguard his friends and village even more. However, he might also face some inner struggles. The power of the Magu Magu no mi could make him feel different from his comrades, and he might have to deal with feelings of isolation at times.

He could become more protective. Since Kiva's powers are powerful, Naruto might feel a greater sense of responsibility to protect his village and friends. He might also be more secretive about his new powers, at least until he fully understands them. And his sense of humor might change a bit, becoming a bit darker or more sarcastic as he gets used to his new identity as someone with Kiva - like abilities.

Naruto's personality might still shine through even as an Arrancar. He's always been determined and kind - hearted. However, he could become a bit more solitary at first as he adjusts to his new form and powers. The Arrancar nature might make him more cautious in some ways, but his basic values of friendship and protecting the weak would remain. He might also develop a bit of an edge, as Arrancars are often seen as more menacing, but it would be a surface change. Deep down, he'd still be the Naruto who wants to bring peace and joy to his village.
