Perhaps in the fanfic, Naruto is mistaken for a new type of Terminator because of his unique powers. The real Terminators try to hunt him down while the humans are initially scared of him but then realize he can be an ally. Naruto could then use his Rasengan and other jutsu to take on the Terminators and their advanced weaponry. He might also try to find a way to get back to his own world while protecting the humans in the Terminator world.
One possible plot could be that Naruto is sent to the Terminator world through some kind of magic or portal. He then has to use his ninja skills to survive among the Terminators. Maybe he teams up with the human resistance and teaches them some of his ninja techniques to fight back.
The plot could start with Naruto already in the Terminator world, not knowing how he got there. He quickly realizes the danger of the Terminators and decides to fight them. As he progresses, he discovers that there are similarities between his world and this new one, like the importance of protecting the weak. He could form bonds with some of the human characters, and together they develop new strategies. Naruto might also encounter a Terminator that has some sort of chakra - like power, which would add an interesting twist to the story. He would have to not only defeat the Terminators but also figure out how to return to his own world and the people he cares about.
The plot might involve the members of team 13 having unique abilities that set them apart from other teams. For example, they could have a special jutsu that they need to master together. And their journey could be about proving themselves to the other ninja in the village. They might start off as underdogs but grow stronger as the story progresses. They could also get involved in some political intrigue within the Hidden Leaf Village, as they are trying to complete their missions and rise in rank.
One possible plot could be that the Terminators are sent to the Naruto universe to hunt down a particular ninja who has knowledge that could change the future of the real world. Naruto and his friends would then have to fight these advanced machines using their chakra powers and ninja skills. For example, Naruto might use his Rasengan against a T - 800, and the T - 800 would use its brute strength and advanced weaponry. It would be an epic clash of two very different worlds.
One possible plot could be that Naruto and Ino are on a mission together. During the mission, they face a dangerous situation that makes them realize their true feelings for each other. As they narrowly escape the danger, Naruto impulsively kisses Ino, and from there, they have to figure out how to deal with their new - found feelings while still maintaining their ninja duties.
Maybe Naruto has discovered a new powerful jutsu that Kakashi isn't aware of. This gives him an edge in the fight and he manages to defeat Kakashi.
In a 'Marry Me' Naruto fanfic, the plot could center around a time - travel scenario. A modern - day girl somehow gets transported into the Naruto universe and falls in love with Kakashi. She decides to break all the norms and says'marry me' to him. This would then involve her trying to fit into the ninja world, dealing with Kakashi's initial shock and disbelief, and the two of them facing various challenges together as they explore their new relationship.
It could be about Naruto having a cold heart due to some traumatic event in his past, like losing someone he loves deeply. This could lead to him becoming more withdrawn and less friendly, and the story might focus on how his friends try to bring back the old Naruto.
If such a fanfic exists, it could be that Naruto gains some sort of special power or training that makes him a speedster while also being godlike. He might use his speed to quickly defeat his enemies before they can react. For example, he could zip around the battlefield, delivering powerful blows in the blink of an eye.
It could be about Naruto being bestowed with the powers of the God of Thunder. Maybe he has to master these new powers while still dealing with the threats in the Naruto world, like Akatsuki.
The story is about a more advanced Terminator, a T - 1000, sent back in time to kill John Connor. Meanwhile, a reprogrammed T - 800 is sent to protect him. There are intense battles as the T - 1000 can shape - shift, making it a very difficult enemy to defeat. John, his mother Sarah, and the T - 800 work together to try and stop the T - 1000 and prevent the future where machines rule.
One possible plot could be that the Terminators are sent to the Naruto universe to eliminate key ninja. Naruto, being Naruto, would not stand for this and would start fighting back. He could use his shadow clones to confuse the Terminators and then use Rasengan to try and damage them.
