It could also be that Naruto has formed an alliance with some other powerful ninja who have knowledge of Itachi's intentions towards Mikoto. Together, they plan a strategy to intercept Itachi and save Mikoto. Naruto, being the protagonist, would be at the forefront of this operation, using his charisma and leadership skills to ensure the success of the mission. He might also use his connection with the Nine - Tails' chakra to gain an edge over Itachi.
Well, one way could be that Naruto accidentally stumbles upon Itachi's plot against Mikoto. Maybe Naruto was in the right place at the right time, and using his ninja skills and his never - give - up attitude, he manages to fend off Itachi and save Mikoto. Naruto is known for his quick thinking in dangerous situations.
One way this could occur in the fanfiction is if there was some sort of genetic manipulation. Maybe a rogue ninja or a mad scientist found a way to combine Uchiha genes with Naruto's. Mikoto, being an Uchiha, had the Sharingan, and through this unethical genetic process, Naruto ended up with the Sharingan. This would also open up a whole new set of abilities and challenges for Naruto as he has to learn to control this new power which is very different from his normal chakra - based powers.
Well, it could be that Mikoto is trapped in a dangerous situation like a collapsing building or a genjutsu. Naruto, with his strong will and powerful chakra, breaks the genjutsu or rescues her from the rubble. He might sense her distress using his Sage Mode or his connection to the Nine - Tails' chakra and rush to her aid.
One way could be through a powerful jutsu gone wrong. Maybe a jutsu that was meant to transfer Itachi's memories to Naruto accidentally transferred his Sharingan as well. In the world of fanfiction, there are often many creative and out - of - the - box explanations.
Well, one possibility is that Naruto has some kind of premonition in the fanfiction. So he quickly rushes to Jiraiya's location where Pein is attacking. And he uses his shadow clones cleverly, distracting Pein long enough to rescue Jiraiya. He could also have some secret help from a new ally or an unexpected power boost from within himself.
Well, Naruto could save Kushina from the Kyuubi in fanfiction through his strong willpower. We know Naruto has an unbreakable spirit. He might be able to communicate with the Kyuubi in a different way, like showing the Kyuubi a future where it doesn't have to be so violent. And by doing this, he could convince the Kyuubi to release Kushina. Also, Naruto might have received some special power or training that enables him to counter the Kyuubi's attack and save Kushina.
In this fanfiction scenario, Naruto could save Fairy Tail from Acnologia using his powerful jutsu. For example, his Rasengan or Sage Mode abilities might be enough to fend off Acnologia. Maybe he could also use his shadow clone jutsu to distract the dragon while Fairy Tail members prepare a counter - attack.
In this kind of fanfiction, one possible plot could be that Mikoto is in danger from an unknown enemy. Naruto, with his strong sense of justice and his powerful ninja skills, somehow discovers her plight. Maybe he stumbles upon a battle where Mikoto is outnumbered and on the verge of defeat. He then jumps into the fray, using his Rasengan or other signature moves to fend off the attackers and save her.
In the fanfiction, perhaps Mikoto is trapped in a genjutsu created by an enemy. Naruto, being very perceptive when it comes to such things, realizes something is wrong. He uses his own chakra to break through the genjutsu and then protects Mikoto from the caster of the genjutsu. This could lead to a bond forming between Naruto and Mikoto, with Naruto seeing her as a sort of mother figure since he lost his own parents early on.
In this fanfiction, Itachi might take Naruto for various reasons. Maybe he sees some potential in Naruto that he wants to cultivate away from the academy's normal teachings. It could also be part of a larger plan to protect Naruto from unseen threats in the academy environment.
One way Naruto could save Whitebeard is if he somehow entered the One Piece world. Naruto is known for his strong sense of justice and determination. If he saw Whitebeard in danger, he would surely jump in to help. He could use his Sage Mode to enhance his strength and perception. With his enhanced abilities, he could sense incoming attacks on Whitebeard and intercept them in time. Also, his ability to communicate with others and form alliances quickly might also play a role in saving Whitebeard.
