Protection is also a key theme. The 'daddy' character usually tries to protect Harry from various threats, whether it's dark wizards or the politics within Hogwarts. Additionally, self - discovery is often part of these fanfictions. As Harry interacts with the 'daddy' figure, he learns more about himself and his potential. For example, in some fanfictions, the relationship helps Harry unlock new magical abilities or understand his own emotions better.
One common theme is protection. Snape often takes on the role of protecting Harry from the various threats in the wizarding world. Another theme is the discovery of family. Since Harry lacks a proper family in the original story, in these fanfictions, Snape can become a surrogate father figure, and there are themes of love and care that come with that new family dynamic.
Sirius Black is a very common 'daddy' character. In the original story, he was Harry's godfather, so it's easy to expand on that relationship in fanfiction. He has the potential to be a loving and protective figure for Harry.
One common theme is the idea of family. Since Harry lacks a proper family with the Dursleys, having Sirius as a father figure gives him a sense of belonging. Another theme could be protection. Sirius is always very protective of Harry in the original story, and in these fanfictions, it's often emphasized even more as a father - son dynamic.
One common theme could be mentorship. Lucius, despite being on the 'dark side' in the original series, could be portrayed as having knowledge and skills that he imparts to Harry in a father - like way. Another theme might be redemption. Lucius could be on a path of redemption and part of that is forming a positive relationship with Harry, almost like a father - son bond. Also, the theme of family could be explored. Since Harry lacks a proper father figure, Lucius could fill that role in a non - sexual, more emotional and guiding way.
The 'daddy sucks' in Harry Potter fanfiction might refer to a negative view of father - like figures. For example, some might explore a negative portrayal of Vernon Dursley. However, this kind of theme can be quite controversial as it goes against the general family - oriented values in the original series.
I don't think it's common because the Harry Potter series already has established family and authority figures like parents and professors. Fanfiction writers usually build on those existing relationships rather than creating a new 'call me daddy' type of relationship. But every once in a while, an author might use it to surprise readers and take the story in a new and unexpected direction.
One common theme is the exploration of relationships. For example, romantic relationships between characters that were not fully explored in the original books, like the relationship between Harry and Hermione. Another theme is the expansion of the magical world, such as new spells or magical creatures. Also, there are fanfictions that focus on the backstories of minor characters, giving them more depth and significance.
Love and sacrifice are also prevalent themes. We see how the love of Lily Potter saved Harry in the original series, and fanfiction often expands on this idea of love being a powerful force. There are also fanfictions that explore the idea of redemption for characters like Draco Malfoy, showing that even those on the wrong side can have a chance at changing and making amends.
One common theme is adventure. Combining the action - packed world of 007 with the magical adventures of Harry Potter makes for some thrilling stories.
Love is a very common theme. Their relationship, from the initial attraction to the deep, abiding love they share as a married couple. Another theme is family. Fanfictions often explore how they raise their children and the Potter family values.
