One potential main character could be a young Iburi Clan member who is just starting to come into their powers. They would be full of enthusiasm and curiosity about their clan's abilities. Another could be an older, more experienced Iburi Clan ninja who has seen a lot and is now a mentor figure. And then there could be a half - Iburi Clan character, who struggles with fitting in both the Iburi Clan world and the world of their other heritage.
A great main character for a Naruto Iburi Clan fanfic could be a female Iburi Clan member who is breaking gender stereotypes within the clan. She could be extremely powerful and determined to show that women in the Iburi Clan can be just as strong as men. Another potential main character is an Iburi Clan outcast. He was shunned by the clan for some reason, but he has unique powers that could save the clan in the end. Also, a main character could be an Iburi Clan ninja who has a special bond with animals, and uses this bond along with his clan's powers to become a formidable force in the ninja world.
An interesting plot for a Naruto Iburi Clan fanfic could be the Iburi Clan facing discrimination within the ninja community because of their unique and somewhat spooky abilities. The main character, an Iburi Clan member, could then strive to change the perception of their clan. They might start by showing off their skills in a positive light during a big ninja tournament. Another plot could focus on an Iburi Clan member who has the ability to communicate with spirits through their smoke powers. This could lead to them getting involved in a supernatural mystery that has ties to the history of the ninja world. And a third plot could be about an Iburi Clan member training under a strict master to master their clan's most powerful jutsu.
Another unique ability could be related to communication through smoke signals. Since they can manipulate smoke, they might have developed a complex system of signals that only members of the clan can understand. This could be used for secret messages during battles or to communicate across long distances within the clan's territory.
One idea could be a story where a young Iburi Clan member discovers a long - lost jutsu of their clan and has to master it while facing challenges from other ninja clans who want to steal it.
A likely main character could be a young ninja who discovers he has the 'One for All' power. He would be on a journey to understand and control it, while also dealing with the normal challenges of being a ninja in the Naruto world, like training and making friends.
Naruto himself could also be a main character. He could visit the Hidden Star Village and interact with the Hoshikage, getting involved in the village's affairs and helping them solve their problems. This would be an interesting way to incorporate the Naruto we all know into the fanfic.
Often, the main character is a young and brave member of the Lion Clan. They might be an outcast or a prodigy within the clan.
One consequence could be that he faces opposition from some clan members who might not be ready to accept him as the leader right away. After all, taking over a clan is a big deal.
Karui could be one of the characters. Since she is from the Hidden Cloud Village and has a connection to the Uzumaki clan through her son's relation to Naruto. Another could be Hinata. Although she is from the Hyuga clan, her love for Naruto and the Uzumaki influence on Naruto's life could bring her into the story. Also, Tsunade, as she has a connection to the Senju clan which is related to the Uzumaki clan.
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.
Boruto, Naruto's son, is an obvious choice. He already has his own story in the Boruto series, but in a fanfic, you can take his character in new directions. Himawari, Boruto's sister, could also be a main character. She has the potential for great power and a unique personality.
