One common theme is often the exploration of Snape's complex character in a different light. His submissive side might be shown in relationships, perhaps in a romantic or platonic power - dynamic context. For example, in some fanfics, he could be submissive to a more powerful magical being.
A great Severus Snape submissive fanfiction could be one where Snape is submissive to a new magical order. This new order has different values and rules from what he is used to. In the fanfic, we can see Snape struggle with his pride as he tries to adapt to this new situation. He might be submissive in terms of following their magical practices and teachings, which are foreign to him. This type of fanfic can be really interesting as it delves deep into Snape's character and his ability to change and submit when faced with new circumstances.

One aspect of fanfictions with a dominant Harry and submissive Severus is the exploration of their relationship outside of the typical Hogwarts hierarchy. Harry, being the hero figure, might use his new - found dominance in a way that helps Severus heal from his past traumas. For example, he could offer Severus the acceptance and understanding that he never had before. It also allows for a different take on their magical interactions, as Harry's power could be shown in a more assertive way while Severus might be more receptive to it in a submissive state.
In some fanfictions, Snape has badass moments when he outsmarts Voldemort. For example, he manages to mislead Voldemort about the location of a crucial magical artifact. He uses his Occlumency skills to his advantage, hiding his true thoughts and intentions while presenting false information in a very clever way. This not only shows his intelligence but also his courage as he risks his life to deceive the Dark Lord.
