Sasuke could be a potential rival. In many Naruto fanfictions, Sasuke is highly skilled in ninjutsu and sharingan - based genjutsu. His rivalry with Naruto, if Naruto becomes a genjutsu master, would be intense. Another could be Itachi. His mastery of genjutsu, like Tsukuyomi, would make him a formidable opponent for Naruto in the genjutsu realm.
Another great one is 'Master of Genjutsu: Naruto's New Path'. In this fanfic, the character discovers new forms of genjutsu and uses them to change the course of the Naruto universe. They train with different characters to enhance their genjutsu skills, and it shows how genjutsu can be a powerful tool in the world of Naruto.
Well, 'Genjutsu Master Naruto: The Ascent' is quite interesting. It details Naruto's exploration of different genjutsu techniques, some of which are his own creations. He uses his newfound genjutsu skills not just in battles but also to resolve conflicts in a more peaceful way. There's also a fanfic called 'Shadow of the Genjutsu Master' which focuses on Naruto's adventures as he masters genjutsu while facing various opponents who also specialize in genjutsu.
Sasuke could be a major rival. Since Sasuke also has strong fire - based abilities, he might see Naruto's growth as a Katon master as a challenge to his own skills. Another potential rival could be a new character introduced in the fanfiction, a prodigy from another village who is also focused on mastering Katon. There could also be older, more experienced ninja within the Leaf Village who might initially doubt Naruto's ability to be a true Katon master and thus become rivals in a sense as they test his skills.
Sasuke could be a rival. He's always been highly skilled and competitive. His Sharingan could potentially see through some of the henge master's henges, creating a constant challenge for the henge master to come up with more advanced henges.
Potential allies could be his friends like Sasuke. Sasuke, with his sharingan and combat skills, could team up with Naruto in battles against those who fear Naruto's newfound genjutsu power. Enemies might include Orochimaru. Orochimaru is always interested in powerful abilities and would likely see Naruto as a threat to his plans.
In some fanfictions, Naruto becomes a master of genjutsu through intense training. He might learn from a new mentor or discover ancient scrolls that teach him advanced genjutsu techniques. This often makes him a more well - rounded ninja, able to deceive opponents in combat as well as use his regular combat skills.
Shisui Uchiha is often a popular character as a genjutsu specialist in fanfictions. His Sharingan - based genjutsu abilities are really powerful and fanfiction writers love to explore different scenarios with him.
There are fanfictions where a genjutsu specialist in the Naruto universe discovers an ancient form of genjutsu. In this story, they embark on a journey to master it, facing various challenges along the way. They might have to overcome the doubts of their sensei and the jealousy of their peers while trying to unlock the secrets of this powerful genjutsu. This makes for a really engaging plot as we see the character grow both in power and character.
Itachi Uchiha is also very common. Fanfictions might expand on his already formidable genjutsu skills. He could be shown teaching other characters his genjutsu techniques or using his Tsukuyomi in new and unexpected ways to defeat enemies.
In some fanfictions, Naruto might become a genjutsu master by training intensively with a reclusive genjutsu expert. This expert could teach him unique and ancient genjutsu techniques that are not commonly known in the ninja world.
