Maybe Naruto is on a mission to rescue someone who has been wrongly sent to the Underworld. Hades, at first, is resistant but Naruto's charm and pure heart make him change his mind. They become friends as they work together to find a way to return the person to the living world. Along the way, Naruto shows Hades the bonds of friendship that exist among his comrades in Konoha, and Hades begins to understand the power of such positive relationships.
One possible plot could be that Naruto, through some kind of magical or interdimensional rift, ends up in the realm of Hades. At first, Hades might be suspicious of Naruto, seeing him as an outsider. But Naruto's friendly and determined nature wins Hades over. They could team up to solve a problem in the underworld, like a rebellion among the souls or a threat from a powerful dark entity. Naruto's ninja skills would be put to the test in this strange new environment, and his ability to make friends would gradually change Hades' view of the living world.
Naruto's powers are mainly based on chakra, which he can use to perform various ninja techniques like the Rasengan or shadow clones. Hades, on the other hand, has power over the dead and the underworld. Their powers could interact in interesting ways. For example, Naruto could use his shadow clones to help Hades manage the souls in the underworld more efficiently. Hades could perhaps use his power to give Naruto a deeper understanding of life and death, which could enhance Naruto's ability to fight opponents who use death - based jutsu.
The 'naruto son of hades fanfic' might involve Naruto being sent on a special mission related to the underworld because of his heritage. Along the way, he meets strange creatures from the realm of Hades. He has to learn to control his powers quickly to survive these encounters and also to protect his friends and village from any threats that emerge from this underworld connection.
Obviously Naruto as the main character. Sasuke could be there, and his relationship with Naruto might change due to Naruto's new identity. There could also be characters from the underworld, like minions of Hades or other mythological creatures.
Well, Naruto's power of the Sage Mode gives him enhanced perception and strength. In a friendship with Hades, he could use this to help Hades better understand the living world and the threats that might come from there. Hades' power to create and control underworldly creatures could be used by Naruto in battle. For instance, Naruto could summon some of Hades' minions to fight alongside him against powerful ninja enemies. Their powers would be a great combination, with Naruto bringing the energy and versatility of his ninja skills and Hades the otherworldly and often - feared powers of the Underworld.
One possibility for a Naruto and Itachi best friends fanfic could be that Itachi, instead of massacring his clan, finds a way to resolve the conflict with the help of Naruto. Naruto, with his unwavering belief in friendship, could convince the Uchiha clan and the village elders to come to a peaceful agreement. Itachi, seeing Naruto's positive influence, becomes his close friend. They could then train together, with Itachi teaching Naruto some of the more advanced Uchiha jutsu, and Naruto in turn sharing his own unique ninja way with Itachi.
Naruto, as the son of Hades, would have some really cool powers. His Rasengan could potentially be infused with the power of the Underworld, making it a much more deadly attack. He could also have the power of persuasion over the dead, which means he could make them tell him secrets or do his bidding. His ability to sense chakra in the Naruto world could be translated into sensing the life force or the 'essence' of beings in the Percy Jackson world. This would give him an edge in detecting enemies, whether they are living or undead.

He might have a darker complexion, similar to the shadowy realm of Hades. His eyes could be a deep, almost black color, with a faint glow, representing his connection to the underworld. His hair might also have a slightly darker hue or even a bluish - black tint, like the color of a moonless night.
