The theme of identity is also often explored. Naruto has always been a character defined by his ninja identity and his goal to become Hokage. When elements from Highlander are added, like the idea of being an immortal, he has to re - evaluate his identity. Is he still just a ninja? Or has this new aspect of him changed him into something more? This theme adds a lot of depth to the fanfiction stories.
One common theme is the clash of cultures. Since Naruto's world has its own set of values, ninja clans, and a unique power system, and Highlander has its own lore about immortals and their rules. When combined, it often leads to exploring how these different cultures interact and adapt to each other.
Power and self - discovery are also frequently explored. Shihoin may start out with certain abilities but then uncovers new powers or aspects of themselves as the story progresses. For example, in some fanfictions, Shihoin has to learn to control a new and powerful jutsu. This theme ties in with the overall theme of growth that is prevalent in the Naruto series.
One common theme is growth. As the character wields the buster blade, they grow in strength and character. For example, they might learn new skills or become more confident. Also, the theme of friendship can be explored. Maybe the buster blade is a gift from a friend, or it helps the character make new friends. There's also the theme of destiny. The blade could be part of Naruto's destiny, guiding his path in the ninja world.
One common theme is the clash of different power systems. Naruto has his chakra and jutsu, while Chronicle has its own set of powers. Fanfictions often explore how these powers interact when the two worlds collide.
Power and corruption are often explored. In a crossover, a 'dark naruto' might be tempted by the different power structures in the new world. For example, if crossing into a world like the Marvel universe, he could be faced with the allure of powerful artifacts or abilities. Another theme is identity. Naruto has to figure out who he is in a completely new setting. Is he still the same ninja from Konoha?
The theme of self - discovery also often comes up. Characters may use the process of mastering the Diable Jambe as a way to learn more about themselves. They might discover hidden strengths or weaknesses as they struggle with this powerful move. It can be a journey of not only physical but also mental and emotional growth.
Another theme is the origin of ninja techniques. Fanfics might focus on how the First Hokage developed his signature jutsu, like his powerful wood - style techniques. They might also explore how he passed on his knowledge or if there were any secrets behind his abilities. This can add a lot of depth to the story as it ties in with the overall Naruto universe's focus on jutsu development.
One common theme is the clash of cultures. Naruto's ninja world has a different set of values and ways of life compared to the Soul Society in Bleach. So, when fem Naruto enters the Bleach world, there's often exploration of how these two cultures interact and sometimes conflict.
One common theme is the combination of different elemental powers. Since Naruto has his own set of abilities related to chakra and Korra is an Avatar with control over four elements, fanfics often explore how these powers can work together or create new forms of combat.
One main theme is power. Since both Naruto and Highschool DxD have characters with different levels of power, in the fanfic, it's often about how Naruto's power compares and combines with the powers in the DxD world. Another theme is friendship. Naruto is all about friendship, and in the DxD world, there are also relationships to be formed and maintained.
Identity is also a big theme. Since the fox transformation is such a big part of Naruto, fanfics will look at how this transformation affects who he is, whether he's seen as more of a monster or a hero because of it. For example, in some fanfics, his friends have to come to terms with this new, more powerful and somewhat wild - looking Naruto. And it really makes for an interesting exploration of relationships as well.
