What could be the true power of Lucy in Fairy Tail in fanfiction?

Perhaps it's a power related to the stars in a more direct way. Like she can draw energy from specific constellations and use it to enhance her attacks. For example, if she summons the power of Orion, she gets super strength and accuracy in her attacks.

Often, her true power is shown as an amplification of her celestial spirit magic. For instance, she might be able to call upon multiple spirits simultaneously without tiring, which is a significant upgrade from her normal abilities in the original series.

If Lucy gets a new power, it will likely change the power dynamics in the Fairy Tail guild. She might be able to take on tougher opponents on her own, which could lead to more solo missions for her.

Maybe she just lost interest in the Fairy Tail world. Fanfiction can be a passing fancy, and her enthusiasm might have waned over time.

Well, one possibility could be that the story focuses on how Lucy adjusts to her new state. Maybe she has to cut back on her guild missions at first. She might worry about how Natsu and the others will react. It could also involve her having strange pregnancy cravings that lead to some comical moments in the guild. And as her pregnancy progresses, she could start preparing a nursery in her home, all while still being part of the Fairy Tail family.

If Lucy never joined Fairy Tail, the friendships and relationships among the characters would form in a very different way. Also, many of the story arcs might not unfold as they do in the original plot.

Well, if we're following the common ships in the Fairy Tail fandom, Natsu could be a likely candidate. Their relationship is very close and there are many hints of a deeper connection between them in the original series. It would make for an interesting story as Natsu would have to grow up a bit to take on the role of a father.

In this fanfiction, perhaps Lucy joins Fairy Tail right after she discovers her magic abilities. This would change a lot of the initial interactions. She could be more naive and inexperienced when joining, which would lead to different dynamics within the guild. Like, she might be more reliant on the others for guidance in using her magic, rather than having some basic skills already when she actually joins in the original story.

One possible plot could be that Midnight uses his magic to trap Lucy in a dream - like world. In this world, he challenges her to various magical tasks. As they interact more, Lucy starts to understand Midnight's past and the reasons behind his actions. Eventually, she manages to break free from the dream world using her Celestial Spirit magic and in the process, Midnight has a change of heart and decides to turn away from his evil ways.

One possibility is that the guild would experience a significant emotional impact. Lucy is a central figure, and her celestial spirit magic has been crucial in many battles. Juvia, with her water magic, is also a strong member. Their departure might lead to a decrease in the guild's overall power. Some members might feel betrayed, while others could be motivated to find out why they left and try to bring them back.
