One key element is the power dynamic. With Harry being sub and Snape dom, it creates an interesting relationship where Snape's authority and knowledge are emphasized. Another element is the exploration of their characters in a new light. Harry may show more vulnerability, and Snape may display different sides of his personality.
There is also the theme of secrecy and forbidden love. Given the nature of their relationship in the original Harry Potter series, a 'dom Harry sub Snape' relationship in fanfiction is often portrayed as something that has to be kept hidden. This secrecy adds an element of excitement and tension to the story, as they have to be careful not to be discovered by others in the wizarding world who may not understand or accept their relationship.
One popular 'sub harry dom snape fanfiction' is 'A Different Sort of Bond'. It delves into the complex relationship between Harry and Snape in a way that shows Harry in a more submissive role and Snape as the dominant one. The story has great character development and explores their interactions in the magical world setting.
Another option is to check out some Harry Potter - focused fan communities on social media platforms like Tumblr or Reddit. People often share and recommend fanfictions in those communities, and you may come across some good 'dom Harry sub Snape' fanfictions through their posts or discussions.
Another way is if there was a magical accident that forces Harry and Snape to rely on each other. For example, they are trapped in a magical realm where only by combining their unique magical abilities can they escape. During this time, they have to put aside their differences and work together. Harry learns about Snape's past traumas and Snape sees Harry's courage and determination up close, which changes their relationship for the better.
For Snape, his usually cold and strict personality could be enhanced in his dominant role. He might be more demanding and less patient. Harry, as the sub, could develop a more submissive side to his usually brave and headstrong personality. He would learn to listen more and be less impulsive.
Well, in this type of fanfiction, perhaps Snape discovers that Harry has a hidden potential that can only be unlocked if he takes on a dominant role. Harry, initially resistant in his submissive position, gradually comes to trust Snape's methods. Their relationship could be set against the backdrop of the ongoing battle against the dark forces in the wizarding world. Snape's knowledge and Harry's courage could combine in unexpected ways as a result of this relationship dynamic.
One idea could be a story where Harry, under the influence of a powerful spell, has to live a day in Severus Snape's memories. He gets to see Snape's childhood, his unrequited love for Lily, and all the sacrifices he made. This would give Harry a new perspective on Snape.
The exploration of Fleur's submissive side is also key. It usually involves showing her trust in Harry and her willingness to follow his lead. In some stories, this is shown through her deferring to his judgment in dangerous situations or relying on him for emotional support. It can also be seen in how she responds to his commands or suggestions in a more submissive manner.
One idea could be a time - travel plot where Harry, through some magical mishap, travels back in time and ends up having to work closely with a young Severus Snape. They could start off as enemies, given their future relationship, but as they face common threats in the past, they gradually develop an understanding of each other.
