A great concept for 'Pet Boy of Fairy Hills' fanfiction could be a conflict between different factions in the Fairy Hills. The 'Pet Boy' could get caught in the middle of it. He might have to choose a side or find a way to bring peace. You could also introduce a mystery element, like a series of strange events happening in the Fairy Hills that the 'Pet Boy' is determined to solve.
There could be other magical creatures in addition to the fairies that are main characters. Maybe a talking animal that the 'Pet Boy' befriends and they team up. This creature could have unique abilities that help the 'Pet Boy' in his adventures in the Fairy Hills.
One idea could be a new character arriving at Fairy Hills and having to adapt to the unique living situation. They could face challenges like getting along with the different personalities of the Fairy Tail mages living there.
There are many interesting stories. Some might focus on the daily lives of the characters in Fairy Hills, like their friendships and small adventures. For example, a story could be about how they prepare for a big festival together, showing their teamwork and individual quirks.
One interesting natsu fairy hills fanfiction could be about Natsu going on a special adventure in Fairy Hills that no one has ever experienced before. Maybe he discovers a hidden room full of ancient magic items.

One idea could be Percy arriving in Beacon Hills and being mistaken for a new supernatural threat. The local pack tries to figure out his powers and intentions. Another could be Percy teaming up with the pack to fight a common enemy that is drawn to the unique energy of Beacon Hills and Percy's own demigod powers. Maybe he also has to adjust to the high school life there while hiding his true identity from most of the students.
Perhaps Natsu is seen as a bad boy because he's from a different background than most of the students at Fairy Tail School. He might come from a poorer part of town and has a rougher attitude. He could be constantly getting into fights with the rich kids who look down on him, and through these conflicts, he learns about friendship and acceptance.
One idea could be exploring the characters' lives after they graduate from college. What new careers do they pursue?

One idea could be exploring what would happen if Timmy's fairies got their powers mixed up.
