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). For example, an OC might be a survivor from a previously unmentioned outpost who has developed special skills to fight Terminators. 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.

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.
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.
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.
Well, in some 90210 oc fanfiction, there are stories about new characters trying to fit into the glamorous world of 90210. They might face challenges like dealing with the rich kids' cliques or finding their true love in this posh setting.
