His personality could become extremely cold and calculating. The power of the Mangekyou Sharingan might make him see others as mere pawns. He no longer values the bonds he once had in Naruto's normal state. Instead, he is only focused on achieving his own dark goals, whether it's power, revenge, or domination.
The Mangekyou Sharingan could make him more paranoid. He constantly fears that others are trying to take his power away. So, he becomes more isolated and trusts no one. He is always on guard and ready to strike first against anyone he perceives as a threat, even if they were once his friends or allies.
Naruto's relationship with his friends in the Hidden Leaf Village would also change. Some might be in awe of his new power, while others might be a bit afraid. For example, Sakura might be worried that the Mangekyou Sharingan could change Naruto's personality. Naruto would have to reassure them that he's still the same person. And he might also use his new power to protect them more effectively, strengthening their bond.
Well, it depends on the specific fanfiction. There are countless Naruto fanfictions out there. Some writers might decide to bestow the Mangekyou Sharingan upon Naruto for the sake of a creative plot twist. For example, it could be a result of some special and unforeseen circumstances in the fan - created story, like a powerful magic or a strange genetic experiment that goes wrong (in a good way for the story).
In Naruto fanfiction, the Mangekyou Sharingan is sometimes used to create new backstories for characters. For example, a character who didn't have the Sharingan in the original might be given one in the fanfiction, and the story could explore how they came to possess and master the Mangekyou Sharingan. This can add a whole new layer of intrigue to the character.
Well, relationships in Naruto Mangekyou Sharingan and Rinnegan fanfiction are often re - defined. When a character unlocks the power of these eyes, their friends may feel a sense of duty to protect them from those who would seek to harm them for their power. However, enemies may target the character's loved ones to get to them. Also, in some fanfictions, characters with these eyes may form a special bond with others who have a similar power or a connection to the origin of these eyes. This can create new alliances and rivalries within the Naruto universe.
One interesting plot could be that Evil Naruto uses his Mangekyou Sharingan to manipulate the memories of the villagers. He makes them believe false things about their past and present, causing chaos in the village. For example, he could make them think that their friends are enemies, turning the village against itself.
Naruto would become more introspective. The Mangekyou Sharingan often comes with a heavy burden and dark secrets. He'd have to deal with the new powers and the potential corruption they bring. For example, he might start to question his own motives more often.
In Naruto fanfiction, it's often portrayed as extremely powerful. It can give characters abilities like seeing through any illusion, predicting an opponent's moves with near - perfect accuracy.
With Sasuke, their relationship would become more complex. Sasuke might be both jealous and intrigued by Naruto having the Mangekyou Sharingan. Jealous because it was always an Uchiha thing, and intrigued because he wonders how Naruto will use it. This could lead to more intense rivalries and also more opportunities for them to understand each other better.
In many Naruto fanfictions, Itachi is often depicted as an extremely powerful Mangekyou Sharingan user. His original abilities in the canon, like Amaterasu, are further enhanced in fan works. Sasuke is also a common focus. His Mangekyou Sharingan's powers can vary greatly from one fanfiction to another, sometimes with new and unique jutsu created by the authors. Another character could be Madara. Fanfiction writers love to explore the full potential of his Mangekyou Sharingan, often giving him abilities that were only hinted at in the original series.
The Eternal Mangekyou Sharingan is a very powerful and significant element in Naruto fanfiction. It represents a high - level evolution of the Sharingan. In fanfictions, it often gives the characters who possess it extraordinary abilities, like enhanced visual powers, the ability to use unique and powerful jutsus.
