Another possibility is that she time - travels to a crucial moment in the history of the gods. Maybe there's a great war among the gods, and Bella's knowledge from her own world gives her an edge. She could use this to side with a particular god or group of gods and change the outcome of the war. This would then reshape the entire world she's in, with new power dynamics and relationships emerging.
One idea could be that Bella Swan travels back in time to a period when the 'gods' in the fanfiction world were creating the universe. She could witness the formation of different realms and races, and her presence might disrupt the natural order, leading to unforeseen consequences. For example, she might accidentally change the destiny of a certain race, which then sets off a chain reaction of events.
She could also time - travel to a time when the gods are in a more dormant state. Bella might explore the ancient temples and artifacts left behind by the gods. During her exploration, she could discover a hidden power or a prophecy related to herself. This discovery could then lead her on a new adventure, as she tries to figure out what it all means and how it relates to her place in this world of gods.
Imagine Bella time - traveling to a period where the gods are bestowing gifts upon mortals. She could be mistaken for a mortal in need of a gift. The god who gives her a gift might give her something that she doesn't understand at first, like the ability to communicate with animals in this world. This new ability would then open up new storylines for her, as she tries to figure out how to use it and what it means for her journey.
One possible scenario in this fanfiction could be that Bella Swan discovers a magical object that enables her to time - travel to the era of the gods. Maybe she has to face various challenges there, like dealing with the different powers of the gods and trying to find her way back home.
Love is a big theme too. Even though she's time - traveling, her love for Edward (or other characters) remains a central part of the story. It might be tested or changed in different ways. Also, the theme of power and knowledge comes up. Bella might gain new powers or knowledge during her time - travel adventures, and this can change the power dynamics in the Twilight - related world she's in. For instance, she could learn ancient vampire secrets that give her an edge.
One idea could be that Bella Swan uses her unique perspective, perhaps from her experiences in the Twilight world, to solve cases in the NCIS setting. For example, her ability to read people, which she might have developed while dealing with vampires and werewolves, could help her in interrogations.
One idea could be a story where Bella discovers the world of the Mikaelsons after being turned into a vampire. She crosses paths with Elijah and they form an unlikely alliance to deal with a common threat in the supernatural world.

A possible plot could be that Bella's status as God's daughter gives her the ability to travel between different realms. She could visit heaven to seek advice from her divine father or explore other spiritual planes. When she comes back to the human world, she has new knowledge and powers. This could make her more confident and independent, which would change the dynamics of her relationships. For instance, she might not be as dependent on Edward for protection, and this could lead to some interesting developments in their love story.
Maybe it's Loki. Loki is known for his mischief and cunning. His complex personality would add a lot of drama to the relationship with Bella. He could bring a whole new level of chaos to the Twilight universe.
