Another possible character could be an antagonist, perhaps a scientist named Dr. Grey who wants to study Lucy because she's not human. He might have ulterior motives that create conflict in the story.
There could be a human friend of Lucy, like a boy named Tom who is curious about her non - human nature and becomes her confidant. He helps her navigate the human world.
A third character could be an elderly woman, Mrs. Brown, who has a kind heart and accepts Lucy for who she is without judgment. She could be a source of wisdom and support for Lucy in the human world.
Erza could also be a main character. Given her strong and motherly side, she would probably take on the role of taking good care of baby Lucy. She might be strict about following a routine for baby Lucy's care. Happy, the flying cat, could be another important character. He could use his unique abilities to search for clues on how to turn Lucy back to normal.
A midwife or a doctor in the area where Lucy ends up could be a main character. Since she's pregnant, she'll need medical assistance. This character could be kind and understanding, providing not only medical help but also emotional support. And then there could be a local villager who initially suspects Lucy but then becomes her ally as they get to know her story.
The father of the baby could be a major character. He could be a loving partner, or there could be some drama if he's not as committed as Lucy. Her best friend could also be in it. The best friend might be the one she confides in about all her pregnancy fears and joys.
There could be a young wizard named Tom. He might be Lucy's sidekick or someone she mentors. He could have his own set of magic skills that complement Lucy's dragon powers. Another character could be an old dragon sage named Zoltar. He might be the one who gives Lucy advice and wisdom about her role as the dragon goddess.
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.
Her best friend could be important. The friend might offer emotional support, babysit sometimes, or give Lucy some parenting tips that she learned from her own family.
One character that would be interesting to include is Mirajane. She has a motherly and observant nature. She could be the one to nudge Natsu and Lucy in the right direction when it comes to their relationship. For instance, she might arrange for them to go on a mission together that she knows will bring them closer. Laxus could also be in the fanfiction. His powerful presence can create a sense of danger or protection. If there's an outside threat to the guild while Natsu and Lucy are exploring their relationship, Laxus could be at the forefront of defending the guild, which would impact Natsu and Lucy's situation. And don't forget about Cana. She could be the one to create some light - hearted chaos, like daring Natsu and Lucy to do something that ends up bringing them closer, such as a bet that leads to a shared adventure.
Well, Lucy is known for her growth throughout the series, and in fanfiction, she continues to develop, especially in relation to Yukino. Yukino, on the other hand, has her own set of skills and a somewhat reserved personality. Their interactions in the fanfiction can range from friendly rivalries to deep emotional bonds. For example, in some fanfictions, they might start as rivals for a certain magic item or a position in a magical competition, but then gradually become friends as they understand each other better.
In Detroit: Become Human fanfiction, Lucy is often depicted as a mysterious and alluring character. She might be an android with unique abilities or a figure with a deep connection to the android revolution. Sometimes she is shown as a guide for other androids, leading them towards self - discovery and freedom.
Lucy may also come across ancient warriors. For example, she could meet a Spartan soldier and be amazed by his combat skills and strict discipline. They could have a brief encounter where the Spartan is curious about this strange girl from another time.
