Well, it could be about Naruto having some special powers inherited from Kronos. Maybe he can manipulate time in some way, like slowing it down during battles to gain an advantage.
Obviously Naruto himself. And probably some of the Greek gods or goddesses related to Kronos, like Zeus who might be wary of Naruto's existence. Also, Naruto's friends from the original Naruto series like Sasuke and Sakura would still be important as they would be part of Naruto's world and might help him deal with the new situation of being the son of Kronos.
Well, the idea of Naruto being the son of Kronos and Rhea in a fanfiction is quite wild. It would mean re - imagining Naruto's backstory. He might not be from the Hidden Leaf Village in the same way. His relationships with other characters would also change drastically. Instead of his normal friends and mentors, he could have interactions with characters from Greek mythology. It would be a huge mash - up of two very different fictional worlds.
If Naruto was the son of Kronos in fanfiction, it would completely upend the Naruto storyline. Kronos is from Greek mythology and has powers like time manipulation. Naruto might inherit such abilities, which would make his battles very different. He could potentially manipulate time to dodge attacks or age his opponents. His journey to become Hokage might be overshadowed by his newfound divine heritage and the powers that come with it.
To develop the character, start with his backstory. Since he's the son of Kronos, he might have grown up in a very different environment compared to other demigods. Maybe he was hidden away by a minor god who felt sorry for him. His past experiences of being alone and shunned because of his father would shape his personality, making him a bit of a loner at first.
He could inherit time - related powers. Maybe the ability to slow down or speed up time, which would be a huge advantage in battles. He might also be able to see into the past or future, which could help him in making strategic decisions.
The main character is surely Percy Jackson. But in this 'son of kronos percy jackson fanfic', new characters might be introduced that are related to Kronos' side of the story. However, the classic characters like Annabeth Chase are bound to be there too. She would be crucial in Percy's journey as she often is in the original stories. Grover Underwood, Percy's satyr friend, would also be a mainstay. His loyalty and friendship with Percy would be tested and explored in this new narrative where Percy has this unexpected connection to Kronos.
It could be one of Kronos' old allies who feels betrayed that Percy is now in a position of power. Maybe someone who was promised a lot by Kronos but didn't get it.
I'm not sure if there is such a specific fanfiction readily available. You could try searching on major fanfiction websites like Fanfiction.net or Archive of Our Own. Sometimes these platforms have very niche and unique fanfictions, but it might take some digging to find one with this exact premise.
The plot could involve Naruto facing opposition from both the ninja world and the entities related to Kronos. In the ninja world, they might be suspicious of his newfound powers and origin. And from the side of Kronos' world, there could be those who don't believe he's worthy of being the eldest son. He would then have to prove himself in both realms.
