One common theme is redemption. Often, Draco is portrayed as trying to make up for his past actions during the wizarding war, and his love interest plays a part in this journey. For example, in some fanfictions, the girl he loves helps him see a different side of life and encourages him to be a better person.
Common themes in Draco Malfoy fanfictions include family dynamics. His relationship with his parents, especially Lucius and Narcissa, is often explored. Another theme is the struggle between good and evil. Draco was on the 'evil' side initially, so many fanfictions show his internal battle between following the dark path or choosing a different, more positive way. Also, there are fanfictions that focus on his academic life at Hogwarts, such as his performance in classes and his relationships with professors.
Well, the theme of redemption often comes up. Since Draco has had a somewhat dark past in the original series, the pregnancy can be a catalyst for him to seek a better path. Also, the theme of love and support is common, whether it's from a romantic partner or his friends.
There are several common themes. The power of forgiveness is one. Given their differences, fanfictions might show how Sirius could forgive Draco for his past actions or how Draco could forgive Sirius for any preconceived notions. Another theme is the exploration of the wizarding society from their different perspectives. Draco, as a Slytherin, and Sirius, as a Gryffindor, have different views on the social hierarchy and magical traditions, and fanfictions often explore these differences.
One common theme is jealousy. Draco is often shown as a jealous character when it comes to the OC. For example, if another male character gets too close to the OC, Draco will act possessively. Another theme is protection. He feels the need to protect the OC from various threats in the wizarding world, which is a way of showing his possessiveness. And there's also the theme of exclusivity. Draco wants the OC all to himself and doesn't like sharing her attention with others.
Friendship or romance is also a very common theme. Despite their animosity in the original books, many fanfictions explore the idea of them becoming friends or falling in love. This could involve a slow - burn relationship where they gradually overcome their prejudices and start to care for each other deeply.
Redemption is another big theme. Draco's family was involved with the Death Eaters, and fanfictions like to show his journey to be a better person with Ginny's influence. She can be the catalyst for his change. There are also stories about them defying the expectations of their respective houses, Gryffindor and Slytherin.
Well, the theme of transformation is quite common. Draco changes for the better because of love. His cold and sometimes cruel demeanor softens. Another is the theme of acceptance. He has to accept the person he loves with all their flaws, and also be accepted himself despite his past. And of course, there's the theme of sacrifice. In some fanfictions, Draco has to sacrifice something dear to him for the sake of his love.
There's also 'The Auction' by Lovesbitca8. This fanfiction presents an interesting scenario where Draco is involved in an unexpected relationship. The plot is filled with twists and turns, and the way the love story unfolds is quite captivating.
One common theme is family loyalty. In a lot of fanfictions, we see Draco and Lucius sticking together through thick and thin, no matter what the situation is in the wizarding world.
Another plot is his struggle with redemption. He realizes the wrongdoings of his family and tries to make amends, but faces many obstacles. This self - imposed journey of redemption, along with the guilt he feels, can be a cause of his depressed state. In some stories, he tries to help the good side secretly, but is constantly afraid of being caught.
