Well, perhaps he could have the ability to inject a special venom. Just like real snakes, this venom might have different effects, like paralyzing his enemies for a short time, which would give him an advantage in a fight.
It's also possible that the snake fangs are related to some kind of magic that only exists in the fanfiction world. For example, they could be used to unlock ancient spells or secrets that are somehow connected to snakes. Maybe there are hidden chambers or magical artifacts that can only be accessed by someone with snake fangs, and Harry, having them, embarks on a journey to discover these secrets.
He might have a more menacing look. The snake fangs could protrude slightly from his mouth, giving him an edgier appearance.
The fangs, of course, are a unique feature. They can add a sense of danger or mystery to the characters. Maybe the art style used to depict the fangs is very detailed and realistic, making the characters look more menacing or alluring.
The Ten Heavens Knight was one of the main characters in 'Battle Through the Heavens.' He was a powerful cultivator and Xiao Yan's foster father. He had a strong sense of justice and responsibility. He was upright, firm, and decisive. At the same time, he had deep cultivation and unique insights. The Ten Heavens Knight was a cultivator wearing a long black robe. His thick black hair was casually scattered over his shoulders. He had a handsome face and deep facial features. There was a faint sense of justice between his brows. His eyes were deep and bright like black gems, shining with wisdom. The Ten Heavens Warrior was tall and muscular, showing his strong physique and indomitable willpower. His voice was low and loud, and it was infectious. People who heard it could not help but feel awe. In the novel, Shi Fangtian was a cultivator with a strong sense of justice and responsibility. Not only did he help Xiao Yan overcome many dangers, but he also taught him how to grow into a true cultivator. His image not only represented justice and power, but he was also a respectable figure that left a deep impression on the readers.
A common reason could be a curse. Some dark wizard might have cursed Harry, and the fangs are a visible manifestation of that curse.
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.
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.
One interesting story could be where Harry discovers he has fangs due to a dark magic spell gone wrong. He has to hide it from his friends at first, but then they find out and help him find a way to reverse it.
In fanfiction, Peter Parker having fangs could completely transform his abilities. He might gain the power of venom injection through his fangs. This could be used to paralyze his enemies. His agility could also be affected, as he might move more like a predatory animal. Additionally, his diet might change, which could lead to new storylines about how he manages his new dietary needs while still being a hero.
Studying ancient magic texts related to serpents might be a way. These texts could contain spells or incantations that can boost the power of snake summoning. Maybe there are also rituals that, when performed correctly, can expand the range of their ability, allowing them to summon snakes from greater distances. Additionally, they could learn from other magical creatures that have an affinity for snakes, like basilisks (if they can find a way to communicate safely), to gain more knowledge about snake magic.
One concept might be that the lemon has a prophecy written on it in snake language. Harry, being the only one who can understand snakes, has to decipher it. This would tie in his Parseltongue ability in a new and exciting way within the fanfiction.
