One common theme is adaptation. In many young snake fanfictions, the snake has to adapt to different environments or situations. For instance, a young snake might have to adapt to a new part of the forest that has different types of prey or predators. Another theme is family. Some stories focus on the relationship between the young snake and its family members, whether it's learning from its parents or dealing with the absence of family. Identity is also a theme. The young snake may struggle to find out who it really is in the context of the fictional world it inhabits. This is seen in stories where the snake has unique abilities or characteristics that set it apart from others of its kind.
Well, 'The Young Snake and the Wise Owl' is also a great piece of young snake fanfiction. Here, the young snake, being naive at first, meets an old and wise owl. The owl becomes a sort of mentor to the snake, teaching it about the ways of the forest, survival skills, and the importance of respecting all living beings. This fanfiction is not only about the snake but also about the relationship between different species in a fictional ecosystem.
It could also be a snake from the Forbidden Forest. There are many unknown and mysterious creatures in there. A snake from that forest might be more in tune with the natural magic of Hogwarts. Harry, being the curious and kind - hearted person he is, might come across it during one of his adventures in the forest and start a friendship with it.
It could be Nagini. Even though in the original series she was more of a servant to Voldemort, in the fanfiction, she could have a different personality and form a bond with Harry.
In " Young Onmyoji ", Qingming had a close relationship with the Flying Snake. Soaring Snake was a god among the Onmyoji. He was considered to be a combination of a demon god and a god, possessing powerful strength and abilities. In the story, Qingming had been taken care of and protected by Flying Snake when she was young, and thus became a fan and believer of Flying Snake.
On the other hand, the relationship between Soaring Snake and Chang Hao was more subtle. Chang Hao was a young Onmyoji. Although he believed in Soaring Snake, he was dissatisfied with Soaring Snake for some reason. In the story, Chang Hao tried to destroy the power of the Flying Snake through some means and expel it from the Onmyoji world. However, Soaring Snake was dissatisfied and angry with Chang Hao's behavior and tried to stop Chang Hao's sabotage. In the end, Qingming and the other Onmyoji worked together to successfully protect Soaring Snake's power and defeat Changhao.
In " Young Onmyoji ", Qingming and Flying Snake were good friends. Soaring Snake was one of the subordinates of the Onmyoji, Seimei, and Seimei was Soaring Snake's foster father. There was no direct relationship between Soaring Snake and Chang Hao.
In some fanfictions, the snake could be a magical gift from a mysterious wizard. Maybe it was given to Hermione because she showed great potential in handling magical creatures.
Sorry, I'm not sure which novel you're referring to. However, according to the information you provided, I understand that you mentioned a plot in a novel where many large snakes fight with the snake king and the snake hunter. In this scenario, the Snake King could be a character who was a small snake but ate the brain of a large snake.
This plot could come from many different novels and stories because many novels involve different kinds of snakes.
The snake might be significant in relation to the Slytherin house. Since snakes are associated with Slytherin, it could be a connection to that side of the wizarding world. It could be a symbol of Harry exploring the darker or more complex aspects of magic that are often associated with Slytherin, even though he's a Gryffindor.
