Friendship is a major theme. Since they are both part of the Fairy Tail guild, their bond is explored, whether it's just a normal friendship or something deeper.
One great Natsu x Lucy x Erza fanfic is 'The Bond of Team Natsu'. It focuses on their adventures together and how their relationships develop in a non - romantic but deep - friendship way. It shows how they support each other through tough battles and how their unique personalities blend well within the team.
The idea of two powerful female characters interacting in a fanfic is always appealing. In strong Lucy x Erza fanfics, we get to see them not only as individual powerhouses but also as a duo. They can learn from each other, like Lucy learning discipline from Erza and Erza learning to be more flexible from Lucy. This mutual growth aspect makes the fanfics very interesting.
There's also 'Lucy and Erza: A United Front'. In this fanfic, their powers combine in really interesting ways. It delves deep into their personalities, with Lucy's determination and Erza's strong leadership. The plot is well - developed and keeps you hooked from start to finish.
One great 'lucy x erza fanfic' is 'The Bond of Celestial and S-Class'. It focuses on their adventures together and how they develop a deep friendship that might be something more. It has some really interesting plot twists.
A popular one is 'The Lucy - Erza Alliance'. In this story, they team up to compete in a magical tournament. The fanfiction is full of action scenes where they combine their powers in creative ways. For instance, Lucy summons a powerful celestial spirit while Erza equips a special armor to enhance their combined attack. It also explores their relationship outside of battles, like how they support each other during the tournament's down times.
Another common theme is self - discovery. Through their interactions and adventures together, both Erza and Lucy often learn more about themselves, their powers, and their place in the world of magic. In some stories, Lucy might discover a new power within herself while Erza learns to be more open about her feelings, all thanks to their friendship and the situations they face together.
You could look for fanfictions that focus on their friendship. There are many stories where they go on adventures together, support each other in battles, and grow as characters side by side.
Often, their relationship develops through shared experiences. Maybe they get stuck in a magical realm together. There, they have to work together to find a way out. In this process, they might have arguments at first because of their different ways of doing things. Erza is more of a strict and by - the - book type, while Lucy is more spontaneous. But as they face difficulties, they learn to compromise and grow closer. In some fanfictions, this eventually leads to a very strong friendship where they are almost like family to each other.
I'm not really in favor of fanfictions that involve abuse themes as they can be quite disturbing. However, if you're looking for fanfictions about Erza and Lucy in general, you might try searching on popular fanfiction websites and filtering for positive or adventure - themed stories instead.
