Another fanfic could focus on Lucy's relationship with Erza. Maybe they team up for a tournament within the Fairy Tail guild. Along the way, they face tough opponents and have to rely on each other's strengths. Lucy's strategic thinking combined with Erza's powerful combat skills would make for an exciting story.
A great plot twist could be that one of the Fairy Tail guys, like Loke, is actually a double agent working for an enemy guild. Lucy discovers this and has to decide whether to trust him again or turn him in. It would create a lot of internal conflict for her.
One great fanfiction is 'A New Adventure'. It shows Lucy in a whole new adventure where she discovers a hidden magic. The story has great character development for Lucy and interesting plot twists.
A good one should have strong character portrayal of Lucy. For example, it should capture her determination and kind heart. If it can show her growth as a wizard, that's even better.
In some fanfictions, Lucy's departure from Fairy Tail could be part of a self - discovery arc. She could feel that she has outgrown the guild in a way, or that she needs to explore the world on her own terms. So she leaves, travels to different places, studies different forms of magic, and then returns to Fairy Tail as a much more powerful and confident mage, ready to contribute even more to the guild.
Some writers portray it as a very emotional event. Lucy might be shown as heartbroken but determined as she walks away from the guild she loves. Her friends are often shown as being in shock or trying to persuade her to stay.
One idea could be exploring how Lucy's pregnancy affects her magic. Maybe she discovers new powers or has to adapt her existing ones. Another plot could focus on the reactions of her friends in the guild. They might be overjoyed and very protective. Also, a story could be written about how she prepares for the baby's arrival while still dealing with any threats to the guild or the magical world.
One idea could be exploring how the other members of Fairy Tail support Lucy during her pregnancy. For example, Natsu might be overprotective, always making sure she's safe on missions or just in general. Another could be Lucy writing in her diary about her hopes and fears for the future as a mother, while also reflecting on her adventures in Fairy Tail.
One great Layla Heartfilia fanfiction could be about her early adventures in the Fairy Tail world that haven't been fully explored in the original series. Maybe it delves into her relationships with other guild members before they were as well - known as they are now.
Erza might see it as a sign of Lucy growing up and becoming more independent. She could view it as a mark of Lucy's determination and might even be a bit envious of Lucy's newfound self - expression. This could lead to some interesting conversations between them about self - identity and how they each represent Fairy Tail.
Well, she could start off being an outcast in Fairy Tail because her ice powers seem so different from the rest. But then she proves her worth by using her ice dragon slayer magic to save the guild from a powerful water - based enemy. The ice would counter the water and she'd become a hero.
