Yes, there could be many 'lucy pantherlily' fanfics that focus on other aspects such as their friendship, adventures they go on together, or their character development rather than sex. Fanfic writers often explore a wide range of themes and relationships in their works.
Friendship is also quite prevalent. The relationship between the reader and Pantherlily is explored in terms of friendship, how they support each other and grow together. It could be through battles or just day - to - day life in their fictional world. For example, they might help each other overcome a difficult situation in the story.
Well, some Pantherlily reader fanfiction might be found on Wattpad as well. However, the quality can vary greatly. You might have to sift through a few to find the really good ones. Usually, stories with more reviews and favorites tend to be better.
One great Pantherlily fanfiction is 'Pantherlily's Adventure'. It shows Pantherlily on a solo mission away from the guild. It's full of action as he battles various foes using his unique abilities. Another is 'Pantherlily and the Lost Artifact' which has an interesting plot where he teams up with some of the other guild members to find a powerful and mysterious artifact.
One interesting Pantherlily OC fanfiction could be about his adventures in a new, uncharted magical realm. It might explore his relationships with other characters in this new setting.
Power and responsibility is an important theme too. As a strong character, Pantherlily has a certain amount of power. Fanfictions may show how he uses that power responsibly within the guild. For example, he might train the younger mages to use their powers better, or he might be in charge of protecting a certain area of the guild. His decisions on how to use his power can have a big impact on the story.
Some fandom - specific forums might also be a good source. Fans often share their own works or recommend other great fanfictions in these forums. You can join relevant Fairy Tail (assuming Pantherlily is from that) forums and start exploring.
Another idea is that the OC is a mage who can transform into a cat - like Pantherlily. But they are not fully in control of this power. Pantherlily takes it upon himself to train the OC to master this ability. Along the way, they get involved in a guild - wide competition where the OC has to prove their worth not just as a cat - like mage but also as a true Fairy Tail member.
One theme could be their training together. They could be learning new spells or combat techniques, and the fanfic could focus on their progress and how they help each other improve. Another theme might be a rescue mission where they have to save a fellow guild member. This would show their courage and teamwork.
