What New Abilities Could Naruto Gain from ANBU Training for the Chunin Exams?

One new ability could be enhanced perception. Characters with Haki could sense the presence of hidden enemies during the Chunin Exams. For example, Sasuke could use Haki to detect any assassins sent by Orochimaru that are lurking in the shadows. Another ability would be the power to intimidate opponents. Just like how Luffy uses his Conqueror's Haki in One Piece, in the Naruto fanfiction, a character like Gaara could use Haki to make his opponents tremble in fear, giving him an edge in battles without even having to make a move.

One skill Naruto could pick up is better chakra control for physical attacks. Gai may show Naruto how to focus his chakra more precisely in his limbs when doing taijutsu. This would make his attacks more powerful. Also, Naruto might learn some stealth techniques from Gai. Gai could teach Naruto how to move quietly and quickly, which is very useful in the Chunin Exams where surprise attacks can be a big advantage.

One possibility is that he gains enhanced speed and stealth. As a chunin, he'd need to be more covert in his missions. He could learn to move so quietly that even sensors would have a hard time detecting him. And his speed could be on a level where he can quickly close the gap between him and his enemies without them realizing it until it's too late.

Even Kakashi could play a role. He might oversee Naruto's training and correct his mistakes, ensuring Naruto is well - prepared for the Chunin Exams.

In the fanfic, Naruto might use intense physical training like running up mountains. This helps build his stamina which is crucial for the exams.

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.

He may gain better control over his chakra. The toads are known for their chakra - related knowledge, so they could teach Naruto advanced chakra control techniques.

Well, in many such fanfictions, there could be intense sparring sessions. For example, Naruto might face off against Sasuke in a new and challenging way during their training for the Chunin Exams. They could be using new jutsu that the original story didn't show.

There could be a new character who is a descendant of an ancient clan that once had the Rinnegan. This character might show up during the Chunin Exams to either help or hinder the current Rinnegan user. They might have some knowledge about the Rinnegan that others don't. Also, an anti - Rinnegan organization's agent could be introduced. They would be there to try and eliminate the Rinnegan user during the exams, thinking they are a threat to the balance of power.

Sasuke is also a key character. His rivalry with Naruto during the training for the Chunin Exams is a major part of the story. Fans are always interested in seeing how he hones his skills, especially his Sharingan abilities.
