Sasuke could also be a main character. His cool and calculating nature could lead to some interesting interactions with Digimon. He might be more interested in the power - related aspects of Digimon and how they can help him achieve his goals.
Since it's a fanfic, it could vary. But likely Naruto and some of his friends like Sasuke or Sakura could be main characters. And maybe some popular Digimon like Agumon or Gabumon could also be main characters in this crossover story.
Tai and his partner Agumon could be the main characters in a love - story - inspired fanfic. Their deep bond could be explored in a more romantic light, like how they are always there for each other and how that could turn into a different kind of love.
In addition to Naruto and Kari, other important characters can be Digimon like Gatomon, who is often closely associated with Kari. And from the Naruto side, characters like Sasuke might also make an appearance in the fanfiction. For example, Sasuke could be intrigued by the Digimon and their powers and might either try to use them for his own gain or end up helping Naruto and Kari in their adventures. Also, other Digimon such as Agumon could play a role, especially if the story involves battles or challenges that require their strength.
Another possible main character could be Gabumon. Gabumon is friends with Patamon and Takeru in the original series. He could join Patamon in exploring the mystery behind the lemon - related happenings in the fanfic. Gabumon's unique abilities might come in handy when dealing with any threats or obstacles that are connected to the lemon - themed plot.
It could be an evil Digimon that has the power to control other Digimon and wants to use them to invade the Naruto world. This Digimon might be jealous of the Digimon King's power and Naruto's connection to it, so it aims to destroy both of them. It could have abilities like mind - control and dark energy attacks.
I think Tsunade could be a main character in a 'naruto himekishi fanfic'. Given her strength and leadership, she could be in charge of the himekishi in the Hidden Leaf Village. Another possible main character could be Rock Lee. His hard - working and determined nature would fit well with the concept of the himekishi. And of course, Sasuke could also be involved. Maybe he has a complex relationship with the himekishi, either as an ally or an antagonist depending on the story's direction.
Obviously, Naruto could be one of the main characters. He could be either a patient or someone helping out at the hospital. Another main character could be Sakura. Since she has medical skills, she could be a doctor or a medic - ninja in charge at the hospital. And then there could be a new character, like a young orphan who is being trained as a medic - ninja at the hospital and has an interesting backstory.
In a 'Naruto of the Sand' fanfic, the main characters could be Kankuro. He has his own unique puppet - using abilities and his relationship with his siblings and the Sand Village could be explored. Another main character could be the Kazekage at the time of the fanfic's setting. Their leadership and decisions would impact the story greatly. Also, Shukaku could be a main character in a sense. Since it is related to Gaara and has a powerful presence, its influence on the events in the Sand Village could be an interesting aspect to write about.
Obviously Naruto himself could be a main character. His determination and never - give - up attitude would be key in facing the Eldrazi threat. Sasuke could also be a main character, his powerful Sharingan and combat skills would be useful in battles against the Eldrazi.
I think Naruto and Itachi could also be main characters in this fanfic. Naruto might look up to Itachi for his self - sacrifice and powerful abilities. Itachi could act as a mentor - like figure to Naruto in the context of the fanfic, guiding him in understanding the Uchiha clan better.
