Well, perhaps in the fanfic, Naruto is on a quest to save his world from a great evil. He somehow discovers that an item or power he needs can be found in Hades' domain. When he arrives, Hades initially wants to keep Naruto out. However, Naruto starts talking about his own experiences of being an outcast in his village at first and how he overcame it. This strikes a chord with Hades, who has always been seen as the 'bad guy' in Greek mythology. So they become friends and Hades helps Naruto get what he needs, and in return Naruto promises to change the perception of the underworld in his world.
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.
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.
Maybe Naruto and PewDiePie meet in a virtual reality setting. Naruto is intrigued by all the strange new technology and PewDiePie is amazed by Naruto's chakra powers. They quickly become friends as they explore this new virtual world together. They could have adventures like racing against each other in virtual cars or fighting virtual monsters. And in the end, Naruto might teach PewDiePie a bit about the importance of friendship and loyalty, things that are very important in his ninja world.
The plot might also focus on their daily lives in the village. They could be shown hanging out, sharing their dreams and fears. Naruto might talk about his goal to become Hokage and Shikamaru could share his concerns about the responsibilities that come with being in the shinobi world. They could also get into friendly competitions like a race across the rooftops of the village, with Naruto using his speed and Shikamaru using his intelligence to find shortcuts.
The 'naruto son of hades fanfic' might involve Naruto being sent on a special mission related to the underworld because of his heritage.

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.
Well, one possibility is that Naruto could have unique powers related to the underworld. For example, he might be able to control shadows in a way similar to Hades' control over the dead. Maybe he could use his underworld - based powers to fight against the evils in the Naruto world. He could also have a connection to nature like Persephone, which would add an interesting twist to his character.

They would learn from each other's skills. Harry could teach Naruto some basic magic spells, and Naruto could show Harry some of his ninja techniques, like the Shadow Clone Jutsu.
The plot could start with Naruto being cursed by a powerful and evil entity. This curse slowly drains his life force and chakra. Hades senses this imbalance in the fabric of the universe. Since Naruto has a special energy that even affects the afterlife realm, Hades decides to save him. Hades brings Naruto to the underworld, where he uses his own unique magic to remove the curse. While in the underworld, Naruto discovers a new form of chakra that is linked to the souls of the dead. He then returns to the shinobi world, stronger than ever, and uses this new power to protect his village and friends.
Perhaps there could be a plot where Naruto and Tenten discover a new form of training. They accidentally stumble upon a hidden area in the forest where the chakra flow is different.
