In some fanfictions, Orochimaru could also be a character related to the Land of Iron. Maybe he is interested in some ancient artifacts or secrets that are hidden in the Land of Iron. His presence would add a lot of mystery and danger to the story. And of course, the various samurai apprentices and masters in the Land of Iron would be common characters as the stories are set in their land.
Naruto is obviously a common character. He often visits the Land of Iron or gets involved in events related to it. Sasuke might also be there, as his journey often intersects with Naruto's. Then there are the samurai from the Land of Iron, like Mifune. He is a respected figure and could play a major role in fanfictions set in the Land of Iron.
It could be Naruto himself as he often is the central figure in many Naruto - related fanfictions. He might be exploring these new lands.
Naruto could also bring about a cultural exchange. The Land of Iron has its own unique traditions and values, and Naruto coming from the ninja world could bridge the gap between the two cultures. He might encourage the samurai to participate in the Chunin Exams or other ninja - related events, and in return, the samurai could teach the ninjas about their swordsmanship and honor - based code.
One interesting storyline could be about a new ninja from the Land of Iron who has a unique jutsu that he brings to the Hidden Leaf Village. This jutsu might be related to the metal - forging techniques of the Land of Iron.
In many 'dark Iron Man' fanfictions, villains like Mandarin could play a role. They might either be the cause of Iron Man's descent into darkness or partners with him in his dark deeds. Additionally, other Avengers such as Captain America could be there. Captain America would most likely oppose Iron Man's actions, leading to some intense confrontations between them.
Naruto's leadership could mean more trade opportunities for the Land of Iron. His connections with the other ninja villages could open up new markets for the samurai's unique weapons and armor. This would boost the economy of the Land of Iron.
One possibility is that Naruto goes there to train in a different style of combat. The Land of Iron is known for its samurai, so he could learn swordsmanship and their unique fighting techniques. This would make him an even more versatile fighter, adding to his already impressive ninja skills.
Often, new original characters created specifically for the fanfiction and possessing the iron bloodline can be popular. They bring fresh perspectives and abilities to the Naruto universe. Also, some minor characters from the original Naruto series might gain more popularity when given the iron bloodline in fanfiction, as it gives them a chance to shine in new ways.
Culturally, Naruto's presence would have a huge impact. He would introduce ninja culture to the samurai. This could include things like ninja tools, jutsu, and the ninja way of life. At the same time, he would learn about the samurai code and their traditions. This cultural exchange could be a central theme in the fanfiction, with Naruto becoming a bridge between the two cultures.
There's often a character named Kyo in some Iron Release fanfictions. He's an orphan who discovers his Iron Release ability by accident when trying to protect his friends from a group of bandits. His unique take on Iron Release is that he can combine it with wind chakra to create razor - sharp iron shards that can cut through almost anything. Another interesting character is Mei. She's a female ninja who uses her Iron Release to create beautiful yet deadly iron flower constructs that can release poisonous spores.
Obviously Naruto himself. He is the main character and his growth and development during this arc are crucial. Then there's Zabuza and Haku. Their story of being outcasts and their complex relationship is very interesting to explore further. Tazuna also plays an important role as he is the reason Naruto and his team are in the Land of Waves in the first place.
