The theme of secrecy also comes up a lot. Werewolves have to keep their condition a secret, and Harry and Draco are no strangers to keeping secrets. This could play into the plot as they try to hide their new werewolf identities from the rest of the wizarding community, all while trying to figure out how to control their new powers or afflictions.
Another theme is the struggle for acceptance. Werewolves are often outcasts in the wizarding world. Similarly, Harry, with his difficult past, and Draco, with his family's reputation, both know what it's like to be not fully accepted. In the fanfiction, they may find common ground in this struggle while dealing with the werewolf aspect.
One possible fanfiction idea could be that Draco Malfoy is secretly bitten by a werewolf. He then has to struggle with this new identity while still trying to maintain his status in the Slytherin house. He might be in constant fear of being discovered, especially by his pure - blood family who have high expectations and strict views on blood purity.
In some werewolf fanfictions, Harry and Draco could be turned into werewolves together. They then have to navigate the werewolf world, which is full of its own politics and hierarchies. This could be a really interesting exploration of their characters as they face new challenges outside the normal wizarding world they are used to.
One common theme is isolation. Since Draco is a werewolf in these fics, he often feels isolated from his friends and family due to his condition. Another theme is self - discovery. He has to figure out how to live with this new part of himself. For example, in many fics, he has to learn how to control his werewolf instincts during the full moon.
One common theme is redemption. Many fanfictions explore Draco's journey towards redemption and how Harry can play a part in it. For example, Draco realizing the error of his ways under the influence of Harry's more noble values.
One main theme is often prejudice. Just as in the original 'Harry Potter' series, werewolves face discrimination, and Draco Malfoy's involvement can either reinforce or challenge that. Another theme could be transformation, not just the physical transformation of a werewolf but also Draco's possible transformation in terms of his beliefs and values.
One common theme is redemption. Draco is often portrayed as redeeming himself and changing his ways. Another is the exploration of the wizarding world from a different perspective, as they are now a couple. And of course, there's the theme of love conquering all, especially considering their past enmity.
Another theme is the exploration of forbidden love. Since they were on opposite sides in the original story, their relationship in the yaoi fanfiction represents a love that goes against the norms of their Hogwarts world. It adds an element of excitement and tension.
The power of forgiveness also pops up a lot. Harry, being the hero he is, often has to grapple with whether to forgive Draco for all the mean things he's done in the past. And this struggle and the ultimate act of forgiveness (or not) can be a major part of the story. Fanfictions might explore how this impacts their relationship and the wizarding world around them.
The theme of breaking social barriers is also prevalent. In the wizarding world, same - sex relationships might face some challenges, and these fanfictions often show Harry and Draco fighting against such prejudices. For example, they might have to deal with the reactions of their families and friends.
Overcoming prejudice is also a big theme. Since they are from different houses with a long - standing rivalry, they have to break through the walls of prejudice that their fellow students and the wizarding world in general have towards their relationship. For example, Gryffindors might be shocked that Harry is soulmates with a Slytherin like Draco.
