If Naruto joins ANBU after the war in fanfiction, it could lead to some interesting character developments. He would have to deal with the darker side of the ninja world that ANBU often encounters. This might make him more cynical or, on the contrary, he could try to change ANBU from within. He'd be able to use his Uzumaki powers and his Sage Mode in more covert operations, which would give Konoha a huge advantage. Also, his relationship with other ANBU members would be complex. Some might respect him immediately because of his war hero status, while others might be skeptical of his more open - minded and friendly ways.
One possible plot could be Naruto facing the internal politics of ANBU. He might struggle to adapt to their more secretive and sometimes morally gray operations compared to his usual straightforward ninja way. For example, he could be assigned to a mission where he has to spy on a former ally, creating an internal conflict within him.
In this fanfiction scenario, Naruto joining ANBU after the Chunin Exams could lead to a major shift in his relationships. His friends like Sasuke and Sakura might not understand his decision at first. Naruto could gain access to new and powerful jutsu within ANBU. Also, he might face internal conflict as the ANBU's sometimes morally gray missions could clash with his own values of protecting everyone and being a hero in the traditional sense.
Well, Naruto might face a whole new set of challenges. In the ANBU, he could be pushed to his limits physically and mentally. Maybe he'd use his unique skills in stealthier ways compared to his normal fighting style. Also, his relationships with other ANBU members would be interesting to explore, as he's a bit of an outlier with his loud and brash personality.
In this kind of fanfiction, Naruto might face some really tough and secretive missions in ANBU. He could be trained in new and deadly ninja techniques. Maybe he would also form some unexpected alliances with other ANBU members, learning from their different skills and experiences.
His relationship with Sasuke would be interesting. Sasuke might be initially suspicious of Naruto's decision to join such a secretive group. But Naruto could convince Sasuke that he's doing it for the greater good of the village and the ninja world, and they could end up working together on some behind - the - scenes missions.
In this fanfic, Naruto might face tougher and more secretive missions. He could be trained in new and deadly ninja techniques specific to ANBU. Also, his relationships with other characters might change. For example, he might become more distant from his old friends as ANBU work often requires secrecy.
One possibility is that Naruto's skills would be put to extreme use in ANBU's more secretive and dangerous missions. His unique abilities like the Shadow Clone Jutsu could be utilized in stealth and assassination operations, but he might also face a moral dilemma as ANBU often deals with morally grey areas.
He could become a more solitary and brooding character. In the ANBU, Naruto might use his pain as fuel for his missions. He could start to distance himself from his old friends, as the nature of ANBU work is often secretive and isolating.
In the 'Naruto Joins the War' fanfiction, Naruto's entry into the war would be a game - changer. His skills as a ninja are well - known, but in the chaos of war, he would have to adapt quickly. He may encounter moral dilemmas on the battlefield, like whether to spare an enemy who surrenders or go all - out for victory. His Nine - Tails chakra could be a double - edged sword. On one hand, it gives him great power, but on the other, it might attract unwanted attention from even stronger adversaries. His interactions with other ninja clans during the war could also lead to new political dynamics in the shinobi world.
If Naruto joins ANBU after the war in fanfiction, his personality would experience a significant shift. His once boisterous and outgoing nature might be replaced by a more stoic and calculating one. He would need to be more discreet in his actions and words. The trust - building that he was so used to in his normal ninja life would be different in ANBU. He would have to be more guarded about who he trusts, which could make him seem a bit colder on the outside. But deep down, his kind heart would still be there. He'd just be more careful about showing it, as ANBU's world is full of deception and he can't afford to be too naive.
