There are often fanfictions where the OC is from the future but has a different origin or mission compared to the known characters. They could be part of an underground resistance group that has developed new tactics to take on the Terminators. These stories can be really exciting as they explore new angles in the Terminator universe.
One interesting concept could be the unique backstories created for Original Characters (OCs).

Another concept could be new relationships formed between the OCs and the existing characters from the Terminator Salvation universe. This could add new dynamics to the story.
There are 'terminator male oc fanfiction' that focus on a male OC being from a different timeline. He might have knowledge of both the human and Terminator technology in a way that no one else does.

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 interesting fanfiction could be about an alternate timeline where Sarah Connor forms an unexpected alliance with a different model of Terminator. This would change the whole dynamic of the fight against Skynet.
One interesting concept could be a crossover with a time - traveling detective story. The terminator could be chasing a target through different time periods and the detective tries to stop it, adding a new layer of mystery to the story.
Another concept might be the TX teaming up with humans. In some fanfiction, a reprogrammed TX could use its advanced combat skills and knowledge of Skynet to fight against the machines that have gone rogue from Skynet's original plan. This creates a really interesting dynamic as it's a former enemy now on the side of humans.

A third idea is that the technology of the Terminator world somehow gets mixed with the magic and technology of RWBY. So there could be Terminators that are powered by Dust or have abilities that combine both mechanical and Dust - based powers. The heroes of RWBY would have to learn about this new threat and find a way to combat it, perhaps by teaming up with some of the human resistance from the Terminator side.
Another concept is the struggle with identity. A terminator - human hybrid might question whether it is more machine or more human. It could be constantly torn between its programmed directives from the Terminator side and the more instinctive, emotional responses of its human side. This internal conflict can create a lot of interesting storylines.
