In a 'bella isn't human fanfiction', Bella could be a spirit that has possessed a human body. She doesn't fully understand human emotions at first. As the story progresses, she starts to feel things like love and friendship for the people around her. She might also discover that there are other spirits out there, some good and some bad, and she has to figure out her place among them while trying to keep her true nature a secret from her human friends.
One idea could be that Bella is a vampire hunter who was turned into a vampire against her will. Now she has to navigate the vampire world while still holding onto her human values. Another could be that she's an alien disguised as a human named Bella, and she's on a mission to study Earth's culture. Maybe she falls in love with a human and has to decide whether to reveal her true identity.
One interesting idea could be exploring how Lucy, not being human, views the human world. Maybe she has unique perspectives on human emotions like love and friendship that are different from our own.
Maybe a plot where Jasper and Bella form an unexpected friendship that develops into a deeper bond. They could start by sharing their different experiences of being turned into vampires. Jasper could tell Bella about his past in the Confederate Army and how difficult it was for him to adapt to the vampire life initially. This could help Bella understand that she's not alone in her struggles. Then, as their friendship grows, they might face some challenges from the rest of the Cullen family who are a bit wary of their closeness.
One idea could be that Bella is a vampire from the start but has been in hiding. She could be on a mission to uncover a secret vampire society that has been causing trouble in the Twilight world. This would change her relationship with the Cullens as she'd be more of an equal, not a fragile human.
One plot idea could be that Jasper and Bella are high school students. Jasper is the new kid, and he and Bella slowly become friends and then fall in love. They face typical high school challenges like dealing with mean classmates and difficult exams together.
Maybe they both volunteer at a local community center. Through their work there, they discover they have a shared passion for helping the less fortunate.

One interesting 'eren isn't human fanfiction' could be where Eren is some kind of ancient spirit reborn. In this story, he has powers that are beyond human comprehension and he uses them to protect his friends in a very different way than in the original plot.

Another plot could involve Stiles trying to hide his non - human nature from his friends, especially Scott. This would create a lot of tension and secrecy in the story. He'd have to constantly come up with excuses for his strange behavior or powers.
Edward could be an interesting character to pair with her. If Bella is a non - human, their relationship would take on a whole new dynamic.

If Bella is some kind of supernatural being, Jacob's wolf nature could create a complex relationship with her, full of loyalty and conflict.

A third plot could involve a world where dinosaurs and humans coexist, and a human and a T - Rex form an unlikely alliance against a common enemy.
