Piper could be a great character to pair with Percy and Annabeth. Her charm - speaking ability and her connection to Aphrodite could offer different perspectives and solutions in their quests. Leo is also a good choice. His mechanical skills and his sense of humor could lighten the mood in difficult situations. And then there's Hazel. Her powers over the earth and her past from a different time period could create some really unique storylines when combined with Percy and Annabeth's story at Camp Half - Blood.
I think Tyson would be an excellent character to include. He's Percy's half - brother and his strength as a Cyclops could be very useful in various situations. His innocence and loyalty also make him a lovable character. Additionally, Clarisse could be paired with them. She has a tough exterior but deep down she's a strong and capable demigod. Her rivalry - turned - friendship with Percy could add some spice to the fanfiction. And of course, Chiron, the centaur, could be involved. His wisdom and guidance are always valuable and could play a crucial role in their adventures.
One interesting plotline could be Percy and Annabeth going on a quest outside of Camp Half - Blood to find a long - lost artifact that has the power to protect the camp from a new, unknown threat. Another could be them having to deal with a rift within the camp that divides the demigods, and they have to work together to reunite everyone. And there could also be a plotline where they time - travel back to the early days of the camp to prevent a disaster that could change the future of the camp forever.
The betrayal of Percy by Camp Half - Blood in fanfiction can also be a way to show Percy's growth and resilience. He has to face the ones he considered family turning against him. This can lead to some really interesting character development arcs, where Percy has to re - evaluate his loyalties and find new allies or even learn to rely more on his own strength.
A fanfiction titled 'Percy and the Forbidden Realm' is also quite good. It takes Percy into a realm that is off - limits in the normal world of the series. He has to navigate through strange and dangerous landscapes while dealing with his own internal struggles. The author does a great job of building the atmosphere of this new realm and making Percy's journey both challenging and thought - provoking.
Their relationship could cause some jealousy among their friends. Maybe there are some demigods who have a crush on either Percy or Annabeth. This could lead to some tension, but also opportunities for growth and understanding. They would have to work through these feelings and find a way to maintain harmony within the group of friends.
Maybe he hates it because it often misrepresents the real Camp Half - Blood or his friends. Fanfictions sometimes take wild liberties with the characters and settings, and Percy might not like how his world is being distorted.
In fanfiction, if Percy hurts Flash, it could be due to Flash's constant bullying. Percy, being a demigod, has powers and a short temper at times. Flash might push him too far, and Percy could accidentally use his powers, like controlling water to trip Flash or something. It would be a moment of self - defense for Percy, and it could lead to a lot of drama in the Camp Half - Blood setting, with other campers having to take sides or deal with the consequences of such an incident.
It could be Chiron, the centaur. He's always keeping an eye on the campers and would likely be concerned if he caught them up to something. He might give them a stern talking - to and some extra chores as punishment.
Nico di Angelo is often underrated. He has such a complex backstory with his relationship to the Underworld and his struggle with his identity. In fanfiction, you could really explore his internal battles more deeply. Another one is Tyson. He's a cyclops and Percy's half - brother, but he doesn't always get as much attention as he could. You could write about his experiences at Camp Half - Blood and how he overcomes the prejudice some of the other campers have towards him.
Definitely Percy himself. He is the main character of the original series, and his actions and decisions drive the story forward. Annabeth is also a great choice. Her intelligence and strategic thinking often complement Percy's more impulsive nature. Grover can bring some humor to the story with his satyr antics.
Percy Jackson is a must - include. He's the hero of the original series and has a lot of adventures and relationships that can be further explored in fanfiction.
