I don't know for sure without reading it. But it could be Naruto himself. Maybe the story focuses on Naruto when he encounters someone or something with bloody fangs and he has to figure out how to handle it.
Another possibility is that the main character could be an original character created for this fanfiction. This new character might be the one with the bloody fangs, and the story could be about their struggle to fit into the Naruto world or their quest for power that involves their unique feature of bloody fangs.
I'm not sure specifically as there could be many different stories under that title. It might be about a character in Naruto having bloody fangs, perhaps related to some sort of transformation or battle situation. For example, it could be about a new form of a ninja that has bloody fangs as a sign of their power.
It could be Naruto himself as he often is the central figure in many Naruto - related fanfictions. He might be exploring these new lands.
It's hard to say for sure without reading it, but it's likely that Naruto himself would be one of the main characters, since it's a Naruto - related fanfiction. He might be at the center of the maelstrom, trying to stop the bloodshed.
The main characters would most likely start with Naruto. In this 'bloody flash' fanfiction, he might be in a situation where he has to fight against powerful and dangerous foes. Sasuke could also be a main character, especially if the story is about their rivalry taken to a more extreme level with lots of bloody battles. Other characters like Jiraiya could also be main characters if the plot involves Naruto's training or some kind of prophecy related to him that leads to these bloody and flash - like events.
In a Naruto fanfic with 'bloody whiskers' in the title, Naruto is surely a main character. Additionally, there could be new characters created by the fanfic author. For instance, an antagonist who is intrigued by Naruto's whiskers and wants to use them for some evil purpose. This antagonist could be a major character driving the plot forward, creating all the bloody and dangerous situations around Naruto's whiskers.
I'm not sure as I haven't read it. But usually in vampire novels, there would be a vampire protagonist, perhaps a brooding and powerful one. And there might be a human character who gets involved with the vampire, like a love interest or a hunter.
Zabuza Momochi is often a popular character in Naruto Bloody Mist fanfiction. His complex past and his skills as a ninja make him an interesting subject for writers. He has a lot of potential for character development in fan - made stories.
Perhaps there are other characters like the heroes or heroines who interact with the Blue Fangs in their love stories. It could be a vampire hunter who falls in love with a Blue Fang, or vice versa. There might also be some sort of magical beings that play a role in either facilitating or hindering their love stories.
Well, Mei Terumi can be quite memorable too. As the Mizukage, she has to deal with the internal politics of the Bloody Mist Village while also being a powerful ninja herself. Her unique jutsu, like her lava - style and boil - style ninjutsu, make her a force to be reckoned with.
Yes, in some fanfictions Naruto has fangs. Writers often add unique physical features to characters in fanfiction to make them stand out more or to give them a more menacing or alluring look. Naruto with fangs can be part of a new take on his character design, perhaps in a more beast - like or otherworldly version of him.
