I'd recommend 'The Betrayed Friends'. In this one, there's a twist where one of Percy's so - called friends turns out to be working against them. It makes for a really interesting read as you wonder who it could be. Another is 'Friends or Foes?' where the line between friendship and enmity gets blurred when they encounter a group of characters with a strange agenda. The twist here keeps you on the edge of your seat.
A really interesting 'Percy Jackson Friends Fanfiction' with a twist is 'The Fake Friendship'. In this story, Percy and his friends initially think they are befriending a group of nice people, but it turns out to be a ruse. The way the real friendships are then re - evaluated and strengthened in the face of this betrayal is really engaging. Another one is 'The Unforeseen Friendship Change'. Something unexpected happens that causes a big shift in how Percy's friends interact with each other. It could be a change in power, or a new revelation about one of their pasts, but it really shakes up their relationships in an exciting way.
One possible fanfiction could be where Percy Jackson, during one of his sea adventures, encounters a mermaid. The 'lemon' aspect could add a bit of a spicy or unexpected element. Maybe the mermaid has some sort of unique power related to lemons, like she can use lemon - scented magic to heal or to create illusions. And their relationship could start off rocky but then develop into a deep friendship or more as Percy discovers more about her world.
One possible fanfiction could be about Percy Jackson accidentally stumbling into Nyx's realm. He's initially terrified but then realizes Nyx has a different side to her. They start to have an unexpected connection, and the 'lemon' aspect could be a budding romantic or at least a very intense friendship that has some flirty undertones. For example, Nyx might show Percy some hidden powers that are only known in her domain, and in return, Percy shares stories of his adventures with the Olympians.
I really like 'Percy Jackson and the Realm of Shadows'. In this fanfic, the author takes the gang on a journey through a mysterious realm filled with all kinds of mythical creatures that we haven't seen much in the original series. It's full of action and adventure.
There's also 'Mortal Bonds'. This fanfic focuses on how Percy's mortal friends are affected by the knowledge of the demigod world. They have to grapple with the fact that their friend is part of a dangerous and magical world. It's interesting to see how they grow and change as they learn more, and how their relationships with Percy are both strengthened and tested.
One great 'Percy Jackson Friends Fanfiction' read could be 'The New Quest'. It takes the characters on a journey outside of Camp Half - Blood, exploring new friendships and challenges. Another is 'Friends in Strange Places' which delves into how Percy and his friends interact with some really unusual mythical creatures while still maintaining their strong bond. And 'Friendship Beyond the Gods' is also a popular one, where their friendships are tested by the interference of the gods but they come out stronger in the end.
There's also 'Female Percy: A New Heroine'. Here, Female Percy brings a fresh perspective to the story. Her fighting style is different, more fluid perhaps. And her relationships with the gods are also unique. Instead of the typical male bravado, she uses her wits and charm to get through tough situations.
Athena might also be a good candidate. Although she and Poseidon have their differences, she could see Percy's potential and befriend him. She could offer him wisdom and strategic advice for his various adventures.
I highly recommend 'The Outcast Demigod'. This fanfiction features an OC who doesn't fit in at first. The author does a wonderful job of showing the OC's struggle to find their place among the other demigods. It has some really intense battle scenes and a lot of heart - warming moments as the OC forms friendships. The story also delves into the OC's backstory in a very interesting way, making it a great piece of fanfiction.
Well, in my opinion, the best Percy Jackson fanfictions are the ones that continue the story after the main series ends. They give us more adventures for Percy and his friends. Also, fanfictions that rewrite certain events in the original story in a creative way can be really good. For instance, if the Battle of Manhattan had a different outcome. And fanfictions that focus on the relationships between the characters, like the friendship between Percy and Grover, are always enjoyable.
I really like 'Percy Jackson and the New Quest'. In this fanfiction, Percy and his friends embark on a new adventure in a different realm. It combines the familiar elements of the original books, like the demigod powers and the Greek mythology, with fresh and exciting storylines. There are also some great character developments that make it a must - read for fans.
