A possible plotline is the discovery of an ancient prophecy related to the fallen angel bloodline in the Naruto universe. This could lead to a race among different factions to either protect or use the power of the character with this bloodline. The character might have to fight against those who want to exploit their power for evil purposes while also struggling with their own identity.
In some cases, characters like Sakura could be main characters. She could play a role in helping the character with the fallen angel bloodline adjust to the ninja world. Maybe she uses her medical skills to deal with any negative effects the bloodline might have on the body. Also, there could be other original characters who are part of the same family or group as the fallen angel bloodline character and are important in the story.
The angel bloodline might be neglected in the fanfiction due to the lack of connection to the existing Naruto lore. In the Naruto world, there are already established power systems and lineages. If the angel bloodline is not carefully tied to these existing elements, it may be pushed to the side. Additionally, the writer might be saving it for a big reveal later in the story, so it appears neglected in the early parts.
It could be an original character created specifically for the fanfiction. Maybe it's a being from a different dimension that somehow ended up in the Naruto universe. It might have some special powers or a tragic backstory that led to it being in conflict with Naruto.
Another possible ability could be purification. The angel bloodline might be able to purify corrupted chakra or evil spirits. In the Naruto universe, there are many instances of dark forces and cursed chakra. A character with this bloodline could be the key to cleansing such malevolent entities. For example, they could purify a village that has been infected by a dark curse or a powerful demon's influence.
I'm sure there are. Fanfiction writers are known for their creativity when it comes to popular series like Naruto. If Naruto has an angel bloodline in a fanfiction, it could mean that his physical appearance might change slightly to have more angelic features. His combat style could also be affected, perhaps incorporating more grace and using abilities related to light or purification. And it would be interesting to see how the ninja world reacts to a being with an angel bloodline in their midst, as it goes against the traditional ninja clans and their known bloodlines.
He could also gain this power as a result of a unique encounter. Let's say he meets a mysterious sage who sees his potential and enhances his abilities. This sage could use some kind of magic or chakra - based technique to give Naruto the boost he needs to send the fallen angel to the moon. It could be related to unlocking a deeper level of his Nine - Tails chakra too.
Maybe Naruto, as a character with his own set of values and a specific world view from his original story, finds the concept of fallen angel fanfiction too far from what he represents. His world is about ninja values like loyalty, hard work, and friendship, and fallen angels might seem out of place in that context.
Maybe Naruto, as a fallen angel, has lost his powers and is trying to regain them while still in the Ninja world. He could be facing discrimination from both the angels (if they exist in the story's universe) and the Ninja who see him as something different.
It really depends on the specific fanfiction. However, Naruto himself is likely to be one of the main characters as it's set in the Naruto universe. There could also be an original character created as the fallen angel. This character would be central to the story, driving the plot with their actions and interactions with the other Naruto characters.
