A third theme could be the power of love and friendship. Despite the challenges of the werewolf aspect, their relationship, whether it be a new friendship or a budding romance, has the power to overcome the difficulties. The werewolf curse becomes a backdrop against which their bond is tested and strengthened.
One common theme is redemption. Draco, often seen as a villain in the original series, might be on a path to redemption with the added werewolf element, and Harry is there to help or at least be a part of that journey.
One common theme is redemption. Since Harry and Draco were enemies before becoming werewolf brothers, their new relationship often leads to Draco's redemption arc. Another theme is acceptance. They have to accept their new werewolf nature and also accept each other as brothers.

One common theme is the struggle with identity. Since Draco is a werewolf, he has to deal with his new identity and how it fits in the existing world. Another theme could be secrecy, as werewolves are often seen as something to be hidden in such fanfictions.
One common theme is isolation. Draco often feels alone as a werewolf in a world that doesn't fully understand or accept his condition. For example, in many stories, he has to hide his lycanthropy from his classmates and teachers at Hogwarts.
Power and control are also common themes. The werewolf's power can be both a threat and an allure to Draco. And Draco, with his own family's influence and power, has to figure out how to handle the werewolf's power. There's also the theme of forbidden love in some of these fanfictions.

In the fanfiction, they may find common ground in this struggle while dealing with the werewolf aspect.
One common theme is redemption. Lucius, being a former Death Eater, often goes through a process of redeeming himself in these fanfictions. Harry, with his forgiving nature, plays a part in this. And Draco, caught between his family's dark past and a new path, also experiences growth towards redemption.
A major theme is the exploration of complex relationships. Given their very different backgrounds and personalities, seeing how they interact and form relationships is fascinating. Also, the theme of self - discovery is common. Each character discovers new things about themselves through their interactions with the other two. For example, Draco might discover that he doesn't have to be defined by his family's past actions, Snape might find new purpose, and Harry might understand more about the gray areas of the wizarding world.
