A cool plot could be that there is a prophecy in both the Naruto and Percy Jackson worlds. It predicts the coming together of a shinobi and a demigod to save both realms from a powerful, interdimensional evil. Percy arrives in the Naruto world, and he and Naruto have to learn each other's skills. Percy teaches Naruto about Greek mythology and how to fight mythical creatures, while Naruto shows Percy the ways of chakra and ninjutsu. They then journey to different parts of the Naruto world, gathering allies and knowledge to face the impending doom.
A great plot could involve a prophecy in both the Naruto and Percy Jackson worlds. The prophecy states that only by combining the powers of the ninja and the demigod can a great evil be defeated. Naruto and Percy are chosen to fulfill this prophecy. Along the way, they face challenges like trying to understand each other's cultures. Naruto has to get used to the Greek pantheon, and Percy has to learn about chakra. They also have to deal with their own insecurities. For Naruto, it could be his fear of not being strong enough without the Nine - Tails' power, and for Percy, it could be his fear of losing his friends in the battle.
One possible plot could be that Naruto and Percy Jackson are somehow transported to a realm where the gods of both their universes co - exist. They are initially confused but quickly realize they need to work together. Naruto's ninja skills and his connection to the chakra (which could be seen as a similar energy to the magic in Percy's world) combined with Percy's control over water and his demigod powers would make for an exciting adventure. They could be tasked with a mission by the gods, like retrieving a powerful artifact that has been stolen and could disrupt the balance between the two worlds.

They start to form a bond, and a harem - like situation begins to develop as Naruto tries to find his way back to his own world.
The most interesting plot could be a tournament - style competition. The demigods from Percy Jackson's world and the ninja from Naruto's world are pitted against each other in a series of challenges. Naruto, as a godlike figure, represents the ninja side. The challenges could include things like fighting mythical beasts, solving magical puzzles, and combat against each other. This would force both sides to learn about the other's strengths and weaknesses and could lead to some unlikely alliances.

Perhaps Percy's niece is suddenly transported to a different realm in the world of Greek mythology. This realm is in chaos due to some dark magic.
