Sasuke can also be a very popular character in mokuton naruto crossover fanfiction. His rivalry with Naruto could take on new dimensions with the addition of mokuton. He might be jealous of Naruto's new power or, on the other hand, be inspired to develop his own powers in response. And there could be epic battles between them where mokuton plays a crucial role.
In Dark Naruto Mokuton fanfiction, one popular type of original character is the healer. Since Naruto's dark side and Mokuton powers could potentially cause harm to himself or others, a healer character is created to keep things in balance. They might have unique healing abilities that work specifically with chakra imbalances caused by the dark side and Mokuton. Also, there are often original antagonists who are specifically after Naruto's Mokuton power because of its rarity and strength when combined with his dark side.
Another potential character could be a new, original character created specifically for the fanfiction. This character could be a young ninja who discovers they have an affinity for the Mokuton Sage powers and has to learn to control and use them while facing various challenges in the Naruto universe.
In this type of fanfiction, it's possible that new characters are introduced. For example, there could be a mysterious figure who has knowledge of the Mokuton and takes Naruto under their wing while he's banished. Another main character could be an enemy who wants to take Naruto's Mokuton power for themselves. And of course, Naruto's friends from Konoha might also be important, as they might be conflicted about his banishment and try to find a way to bring him back.
Obviously Naruto himself is a central character. His popularity from the original series brings a lot of attention. Then there might be characters from the crossover world that gain popularity. For example, if it's a crossover with a Final Fantasy world, characters like Cloud or Squall might be popular in the fanfiction.
Definitely Naruto and Superman. They are both iconic characters in their respective universes. Their different power sets make for an interesting comparison. Another popular crossover is between Sasuke and Batman. They both have a dark and brooding side. And of course, Sakura and Wonder Woman. The contrast between Sakura's ninja skills and Wonder Woman's superhuman abilities is appealing.
A potential main character could be a long - lost relative of Hashirama who has the mokuton ability but has been neglected in the main Naruto story. This character could then embark on a journey to discover their true power and place in the ninja world.
Hashirama Senju is likely to be a common character as he was the one with the mokuton ability in the original Naruto series. Also, characters like Naruto himself might be involved as he often stands up against unfairness in the story, so he could be in the fanfic to oppose the council. And perhaps some of the council members themselves would be prominent characters as the ones being 'bashed' in the story.
One interesting concept could be Naruto having a special connection with mokuton (wood style) that is different from what we see in the original series. For example, he might be able to combine mokuton with his regular jutsu in unique ways, like a mokuton - Rasengan fusion.
The mokuton ability is really cool. In Naruto, it's unique and powerful. Fanfictions about it allow fans to explore more of what could be done with this power. For example, seeing Naruto use mokuton in new and creative ways in battles is exciting.
The popularity of 'naruto mokuton fanfiction' lies in the unique nature of mokuton abilities. It's something that not many characters in Naruto possess, so it creates a sense of mystery. Fans are drawn to stories that explore these rare powers further.
