I'm not entirely sure as I haven't read this specific fanfiction. But 'submissive' in fanfiction often implies a certain character trait or role within the story. It could be that Harry in this fanfiction has a submissive personality compared to his more common portrayals, which makes it rare.
You could start by looking on popular fanfiction websites like Archive of Our Own (AO3). They have a large collection of fanfictions and you might be able to find it there by using the search function.
I'm not entirely sure as it sounds like a rather unorthodox fanfiction concept. It might involve reimagining Harry Potter in a relationship where he is in a submissive role, which is quite different from the original character portrayal in the official books.
Well, without reading the specific fanfiction, it could be about Harry Potter having a familiar that is very uncommon in the wizarding world. Maybe it's a magical creature not often seen as a familiar, like a Thunderbird or a Kelpie. It could involve adventures where this rare familiar helps Harry in some unique ways, such as using its special abilities to solve mysteries or fight against dark forces.
Well, relationships are a big theme. In submissive Harry fanfiction, his relationships with friends, mentors, or love interests are often re - explored. His submissive nature can either strengthen or strain these relationships. Also, self - discovery is common. Harry discovers new aspects of himself when in a submissive state, like hidden strengths or emotions. It's also about power dynamics. How he navigates power in a submissive role, whether it's magical power or social power within Hogwarts or the wizarding world.
One characteristic could be a re - imagining of Harry's personality to be more submissive, which is a big departure from his canon self. The snake aspect might introduce elements of snake - like behavior or abilities into Harry's character. For example, he could have a connection to snakes in a more profound way than in the original books.
Well, in these fanfictions, a cute submissive Harry often shows a great deal of vulnerability. He might be more open to others' opinions and guidance, like relying on his friends or mentors more. For example, he may ask for advice instead of charging ahead on his own.
In such a fanfiction, Harry might show characteristics like being obedient. He may follow the commands of his owner without much resistance. For example, he could be always eager to please and do tasks assigned to him.
In Harry Potter fanfiction, a rare ability could be the power of true prophecy. While there are seers in the original series, in fanfic, a character might have the ability to see not just vague glimpses of the future but detailed and accurate prophecies that can change the course of the wizarding world. Also, the ability to heal any wound or illness instantaneously could be considered rare. This would make the character a sort of super - healer, far more powerful than Madam Pomfrey. And some fanfictions might explore the ability of a wizard or witch to transform into any object or creature at will, not just those within the Animagus transformation limits.
In Harry Potter fanfiction, some rare familiars could be a phoenix. It's extremely rare in the normal wizarding world, and in fanfic, it might be given to a special character as a familiar, symbolizing great power and rebirth.
I'm not sure specifically as there could be many different takes on a Twilight fanfiction with that title. It might be about a character in the Twilight universe being submissive in certain situations, perhaps in relation to power dynamics among vampires, werewolves or other characters.
