Sasuke could also be a main character in such a fanfiction. Given his brooding nature and his search for power, the addition of dark angel powers could take his character in an even more complex direction. He might be more tempted by the dark side that comes with the dark angel powers.
It really depends on the specific fanfiction. However, it could potentially include Naruto himself, as he is a central character in the Naruto universe. And perhaps some of the main characters from 'Dark Angel' like Max might also be incorporated. There could also be new original characters created by the fanfiction author to bridge the two universes.
A human character who becomes involved with the dark angel could also be the main character. For example, a young woman who discovers the dark angel and tries to understand it, and through their interactions, she changes and so does the angel.
Another option could be a hybrid character. Maybe a half - Dark Angel, half - Star Wars species character. This character would be constantly torn between the two sides of their heritage, having to decide whether to embrace their Dark Angel side, which might be more about physical strength and survival, or their Star Wars side, which could involve the moral choices related to the Force.
Since we have no clear information about this 'angel of dark novel', it could be the angel itself. But it's also possible that there are other important characters. Maybe there is a human who has a special connection with the angel, and in that case, either the angel or the human could be considered the main character. It really depends on how the story is structured and what the focus of the narrative is.
Maybe some ancient demonic clans that have a long - standing feud with the angels. They sense Naruto's transformation into a fallen angel and see him as an easy target or a way to get back at the angelic realm. These clans could have their own unique powers and abilities that Naruto would have to face.
I'm not sure as I haven't read this specific 'Dark Angel Dale Novel'. But usually, the main character is the one around whom the main plot revolves.
It could be an original angel character that you create. This angel could have special powers like the ability to heal any wound or the power to manipulate light in unique ways. They would enter the Fairy Tail world and become the central figure in the story, interacting with all the well - known Fairy Tail characters.
The Hidden Leaf Village elders could be main antagonists. If Naruto turns dark because he feels betrayed by the village, they would be the ones representing the establishment he is against. Their conservative and sometimes self - serving ways could be the catalyst for Naruto's transformation, and then they would be the ones trying to stop him as he becomes a threat to their power and the village's traditional order.
The other Tenshi would be a main character as well. She might bring new powers or a different view of the angelic side compared to what we've seen before in the D.N. Angel series.
A brooding vampire could be the main character. He has lived for centuries and has seen the worst of humanity. However, he decides to use his superhuman strength and speed to protect a small town from other supernatural threats that lurk in the night.
