Some common themes in dark immortal Naruto fanfiction include the exploration of Naruto's inner darkness. As he becomes immortal, his experiences may bring out a side of him that was previously hidden. There could also be a theme of redemption. Despite his dark and immortal state, Naruto may strive to find a way to use his powers for good or to atone for any misdeeds caused by his transformation. Additionally, the theme of eternal loneliness might be present, as he outlives his loved ones.
Another theme is self - discovery. As Naruto faces his dark side, he often learns more about his true nature, his powers, and his place in the ninja world. It's like a journey of self - exploration but with a dark and dangerous twist.
One common theme could be the struggle between Naruto's dark side and his newfound Mokuton abilities. Maybe he has to battle inner demons while also coming to terms with this powerful new element. Another theme might be how his friends and the village react to this darker Naruto with Mokuton powers. Do they fear him? Or do they try to help him control it? It could also explore how Naruto uses Mokuton in unique and unexpected ways in his darker state, perhaps using it more aggressively or defensively than he would in his normal self.
Often, the theme of power corruption can be seen. Naruto might gain too much power too quickly and it starts to corrupt him, making him dark and angry. He could lash out at those he once considered friends because he no longer sees the world in the same way. His anger could be directed at the ninja world in general for its never - ending cycle of violence and hatred that he has now become a part of in a more negative way.
A common theme could be redemption. Maybe in the fanfiction, there's an attempt to redeem Mephiles through Naruto's influence. Naruto has that optimistic and persevering nature that might be used to try and turn Mephiles away from his dark ways. Another theme is the clash of different worlds. Naruto's ninja world and the world where Mephiles comes from could have different rules, cultures, and powers. Exploring how these differences play out when the two characters meet is an interesting theme. And there's the theme of identity. Naruto has his own identity as a ninja and a hero in his world, and Mephiles has his identity as a dark entity. How these identities are challenged or changed in the context of the fanfiction can be a great theme.
One common theme is the exploration of Naruto's hidden or suppressed dark side. It might show how Naruto's past traumas, like being an orphan and facing discrimination, could have led to a darker personality. Another theme could be the clash between Naruto's dark avatar form and the values of the Hidden Leaf Village. This can create a lot of internal and external conflicts in the story. And the theme of redemption might also be there. Even though he has a dark avatar form, Naruto could be on a journey to redeem himself and find his true self again.
One common theme is loneliness. Since Naruto is immortal, he may outlive all his friends and loved ones, which can lead to a deep sense of isolation. Another theme could be power. His immortality might be tied to some new or enhanced power, and he has to learn to control it. Also, there's the theme of legacy. As he lives on, he has to think about the kind of mark he wants to leave on the ninja world.
Power corruption is also a big theme. His new hanyou powers in the 'dark' concept can be very strong, and there's often a temptation for Naruto to use them in ways that might not be ethical. This leads to internal conflicts within him as he battles between his good side and the darker impulses that come with his hanyou nature.
The theme of friendship also frequently appears. Despite their differences, Naruto is known for his ability to befriend others. In these fanfictions, he forms a bond with the dark elf characters. This friendship can be a source of strength, helping them both to grow and face the difficulties in the fictional universes they inhabit. It can also be a driving force in the plot as they support each other through various trials.
One common theme is the exploration of Naruto's inner darkness. It often shows how Naruto might have turned out if he had faced more difficult situations in his life. Another theme is the corruption in the ninja world, like the hidden agendas of the villages or clans.
Betrayal is a common theme. For instance, Naruto might be betrayed by his comrades or the village he loves, which leads to a cold and dark turn in his life.
