Power and identity are also common themes. Percy's own powers as a demigod and his connection to the Olympians play a big role. He often has to figure out his place in the Olympian hierarchy and how to use his powers to protect those he cares about. Fanfictions usually explore how Percy's identity evolves in relation to the Olympians.
If the Olympians read Naruto fanfiction, it could potentially influence their view of mortals' creativity. They would see how mortals can take an existing fictional world like Naruto and expand it in so many different ways. They might also start to think about how their own stories could be re - imagined in a similar way. Some Olympians might even get inspired to try and create their own 'fan - like' stories within the context of Greek mythology, although they would probably keep it to themselves out of pride.
There's no public information indicating that there are specific Olympians known for reading Naruto fanfic. Most of what we hear about Olympians is related to their sports achievements, training regimens, and personal lives in the context of sports. However, that doesn't mean there aren't some Olympians who enjoy it privately.
There could be a new, mysterious force that is neither from the Naruto world nor fully part of the Olympian world. This force wants to disrupt the balance between the two worlds and sees Naruto as the key to achieving its goals. It could manipulate both sides and create chaos.
Obviously Zeus is one of the most important characters. Also, other Olympians like Hera, Poseidon, and Athena are likely to be important. Maybe some Titans who play a role in the story of the Olympians' rise too.
The main plot likely revolves around Zeus and how he came to power and led to the rise of the Olympians. It probably details his battles, his relationships with other gods, and the establishment of the Olympian order.
Zeus, being the king, might be a bit dismissive at first. He's used to grandeur and the power plays in Greek mythology. But he could also be intrigued by the strong leadership shown by characters like Naruto. Athena would likely be very analytical, studying the problem - solving and battle strategies in the fanfiction. Ares, on the other hand, might be bored as he prefers more straightforward combat scenarios like in Greek battles.
