Well, Naruto for sure. But also, characters from the Hidden Leaf Village's higher - ups like Tsunade might be main characters. They would have to deal with the implications of Naruto's new identity on the village. And from Khal Drogo's side, a character who was a close friend or advisor to Khal Drogo could be brought into the story. This character could act as a link between Naruto and his father's past, and help him navigate the challenges that come with being the son of such a powerful figure.
Obviously, Naruto would be one of the main characters. Since he is the son of Khal Drogo in this fanfic, he would be central to the story. Another potential main character could be Sasuke. His relationship with Naruto could be even more complex now, as Naruto has this new and strange heritage. And maybe one of Khal Drogo's most trusted warriors could also be a main character, coming to the Naruto world to help Naruto understand his father's side of the family and teach him things about his newfound heritage.
Naruto is a given as the main character. Then there could be characters like Kakashi. He would play an important role in guiding Naruto as he deals with the implications of being the son of Khal Drogo. Also, a female character from Khal Drogo's tribe, perhaps a love interest for Naruto, could be a main character. She could introduce Naruto to the culture and traditions of his father's people and be by his side during his adventures.
