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.
I'm not sure if there is such a specific fanfic. There could be fan - created works out there that combine Naruto and the Terminator concept, but it's not a very common or mainstream crossover that I'm aware of.
In a post - apocalyptic world, a female resistance fighter finds a damaged Terminator. Instead of destroying it, she begins to repair it. As she works on it, she starts to see it not just as a machine but as a being with a certain charm. They go through many battles together, and gradually, an unexpected love blossoms between them.
There are terminator fanfics that focus on alternate timelines. For example, a story where Sarah Connor manages to prevent Skynet from ever being created in a completely different way than in the movies. This can involve new characters and complex plot twists.
One interesting 'oc terminator fanfic' is 'The Terminator's New Ally'. It has a unique plot where an original character teams up with the terminator. The character development in it is quite engaging.
The integration with the Terminator universe. It should follow the rules of the Terminator world while also adding new elements. Like in some fanfics, the OC might find a way to hack the terminator's systems in a completely new and unexpected way. Also, good character interactions are important. If the OC can have complex relationships with the existing terminator characters, like friendship or rivalry, it can make the story more engaging.
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.
It's really hard to say. The Terminator has advanced weaponry and is almost indestructible. But Naruto has the power of the nine - tailed fox. If Naruto were to go into his full - power mode, he could potentially cause a lot of damage to the Terminator. However, the Terminator doesn't feel pain and can keep coming. So it could be a very long and drawn - out battle.
In a Naruto becomes a Terminator fanfiction, it could start with some sort of time - travel or interdimensional rift. Maybe a jutsu gone wrong sends Naruto to a world where the Terminator technology exists. Then, Naruto, with his ninja skills and strong will, might adapt to the new environment. He could use his chakra in unique ways combined with the advanced weaponry of the Terminator world.
