There could be original characters created specifically for this fanfic that are main characters. For instance, a skilled female ninja who is an expert in espionage and has her own motives and backstory. She could play a crucial role in the operations of the spy network, perhaps leading a team or being in charge of a particular area of intelligence gathering.
Well, Naruto himself might be one of the main characters. He could be using his ninja skills in a different way as part of the spy network.
Maybe there's a plotline where the spy network has to infiltrate a powerful enemy organization. They would need to use their unique skills and intelligence to overcome various obstacles and security measures.
One of the key members could be Hinata. Her Byakugan ability allows her to see long distances and detect hidden enemies. This makes her great for gathering intelligence. Another might be Kiba with Akamaru. Their sense of smell can be used to track people and detect any strange scents that might indicate a threat or something unusual going on. Also, Sai could be in the network. His calm and calculating nature, along with his artistic abilities which could be used for coded messages, would be very useful.
The Shangjing spy network was handed over to Guo Baokun. After Fan Xian and the oil shop manager exchanged secret signals, the manager led Fan Xian into the rear courtyard and spread the conversation between him and the empress dowager. Fan Xian promised the shopkeeper that if the mission was successful, he would arrange for the shopkeeper to return to the Qing Kingdom to reunite with his family. The Shangjing intelligence network would be taken over by Guo Baokun. The shopkeeper did not receive such an order, but Fan Xian showed his commissioner's waist token and clearly stated that Guo Baokun was his direct subordinate. Therefore, the shopkeeper had no choice but to agree to bring Guo Baokun to meet the secret agent in Shangjing.
Sasuke could be a good main character. He has the skills and the motivation. He's always been on a quest for power and knowledge, which could easily be tied into a spying storyline. He could be spying on other villages to gain an edge for Konoha or for his own personal vendetta.
I'm not entirely sure as 'lemon' in fanfiction often refers to something with adult or sexual content which is not appropriate to discuss in detail. But generally, a 'Naruto spy network' in fanfiction might be about a secret network of spies within the Naruto universe, perhaps involved in political intrigue, uncovering secrets of different ninja clans or villages.
Obviously, Naruto is the main character. He is the one who becomes this 'god - like' figure in the fanfic. But there are also other important characters like Sasuke. Sasuke might play a role in either supporting Naruto's new power or being in conflict with him because of it.
In certain 'naruto wings fanfic', Kakashi could be a main character. His experience and wisdom would be valuable in guiding the younger characters with their newfound winged powers. He might also have his own secrets related to wings that are revealed in the fanfic. And of course, there could be fan - made original characters who are the main focus, with their own unique wing abilities and backstories that interact with the Naruto universe.
Well, Naruto is surely one of the main characters. Since it's related to Naruto, he'll be at the center of the story, probably with enhanced abilities.
Often, the main character is the merchant. They could be a young entrepreneur trying to make a name for themselves in the Naruto world. Besides, there could be supporting characters such as other merchants who are competitors. And of course, ninja characters like Kakashi or Sakura could be involved too. For example, Kakashi might come to the merchant to buy a new set of kunai, and through this interaction, a deeper relationship or story arc could develop.
Perhaps the main characters would include some of the important ninja leaders. For instance, Tsunade, as the Hokage, would be very involved in any legal matters in the Leaf Village. And Shikamaru, with his high intelligence, could be involved in devising or interpreting laws. He has always been good at strategic thinking which could be applied to legal situations.
