One great 'Percy Jackson x Diana fanfiction' is 'The Meeting of the Demigods'. It has an interesting plot where Percy and Diana first cross paths during a quest. The story does a great job of portraying their different powers and personalities.
A common theme is the clash of different mythologies. Percy comes from Greek mythology and Diana from Roman mythology. Fanfictions often explore how these two different mythological backgrounds interact.
Annabeth could be a strong ally. She has always been there for Percy, and even though his parentage has changed, her loyalty might still hold. Grover too. He's Percy's best friend and would likely stand by him no matter what. Another potential ally could be the Hunters of Artemis. Since Diana is another name for Artemis, they might see Percy as someone they need to protect and help, especially if he is involved in something that concerns the goddess.
One interesting plotline could be Percy having to deal with new powers inherited from Diana. For example, he might have an enhanced connection to nature and animals, which could lead to adventures where he has to communicate with forest spirits to save his friends. Another plotline could involve Percy facing off against a new set of enemies who are specifically targeting him because of his relation to Diana. These enemies might be ancient foes of Diana's that now see Percy as a threat to their plans.
Percy Jackson's power over water could be really interesting when combined with Diana Prince's combat skills. For example, Percy could create water barriers or even water weapons for Diana to use in battle. His ability to control the sea could also be used to quickly transport them across large bodies of water during their adventures together.
A really good 'Percy Jackson x Clarisse Fanfiction' is 'When Percy and Clarisse Train Together'. In this one, they are forced to train together and through the process, they discover new things about each other. They start to respect each other more and it's a great read for those who like character - development - focused stories.
One aspect of 'Percy Jackson x Gaia Fanfiction' could be the unique power dynamics. Percy has his own set of powers from being a demigod, and Gaia is an extremely powerful primordial goddess. Their interaction in fanfiction might explore how Percy, with his courage and skills, contends with Gaia's all - encompassing power. It could also delve into the moral and ethical implications of Percy's relationship with such a powerful and ancient being.
One plot idea could be that Percy Jackson, while on a quest, accidentally stumbles into Diana Prince's world. They team up to fight a common enemy that threatens both the demigod and the Amazonian worlds. Maybe a powerful ancient evil that has the ability to disrupt the balance between the mortal and the divine in both their realms.
The theme of sacrifice is also quite common. Sally has already made sacrifices for Percy in the original series, and in fanfiction, this can be exaggerated or explored further. It could be something as simple as sacrificing her own comfort for Percy's well - being, or more extreme sacrifices in the face of greater threats. Additionally, the theme of Percy understanding Sally's sacrifices and how it affects his view of her as a mother and a person is also often explored in these fanfictions.
One idea could be a story where Michael Jackson and Diana Ross collaborate on a huge musical project. They start by sharing their different musical visions and gradually combine their styles to create a new genre of music that takes the world by storm.
