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.
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.
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.
