A possible plot in such a fanfiction could involve Draco seeking help from unlikely sources. Maybe he goes to Hermione Granger for advice, since she's known for her intelligence and knowledge. This could lead to an interesting dynamic between the two former rivals. The story could also explore how Draco deals with the practicalities of pregnancy, such as dealing with morning sickness while still trying to maintain his status in the wizarding community.
There are some out there. You can start by looking on fanfiction platforms like FanFiction.net or Archive of Our Own. However, keep in mind that these stories often deviate from the original 'Harry Potter' canon and might have different interpretations of the characters. Some might focus on how the wizarding world reacts to such an unexpected situation, while others might explore the relationship changes between Ginny and Draco.
One possible plotline could be that they are forced into an arranged marriage by their families. At first, they are hesitant and cold towards each other. But as time passes and Luna discovers she is pregnant, they start to open up. Draco, who has his own insecurities from his family upbringing, slowly realizes he wants to protect Luna and their unborn child. They could face opposition from the wizarding community due to their past associations (Draco being a former Death Eater's son and Luna being the 'loony' Lovegood). However, they stand together against all odds, learning to love and support each other throughout the pregnancy.
In a fanfiction, Draco could be chosen as an unwilling participant in the Triwizard Tournament. Maybe the Goblet of Fire was tampered with by some dark forces who thought Draco would be an easy puppet. As he goes through the tasks, he starts to show unexpected courage and loyalty, much to everyone's surprise.
Maybe the plot could center around Draco's relationship with the father of the child (assuming there is one in the fanfiction). If it's someone unexpected, like a Muggle or a Gryffindor, there would be a lot of conflict and drama. They would have to figure out how to co - parent in a world that might not be accepting of their situation. And Draco would have to navigate his feelings for this person while also dealing with the physical and emotional aspects of pregnancy.
There are many fanfictions on this topic. Some might explore how Narcissa's pregnancy would change her relationship with the Malfoy family and their stance in the wizarding world. It could also show how she might deal with the impending birth during the chaotic times in the story.
A possible fanfiction plot could be that Draco, now a girl, discovers new magical abilities that were suppressed in his male form. These powers could be related to a more intuitive connection with magic, something that is often associated with femininity in the wizarding world. This newfound power could put her in a position where she has to choose between using it for the benefit of Slytherin or for the greater good of Hogwarts, creating a moral dilemma for her character.
In a fanfiction where Draco Malfoy and a Muggle have a baby, there could be a lot of conflict. The wizarding world might not accept the baby easily due to its Muggle heritage. Draco could struggle with protecting his family from the prejudice of his own kind. He might have to make difficult choices between his loyalty to the wizarding world and his love for his Muggle - born family.
One interesting Draco Malfoy drunk fanfiction is 'Midnight Indulgence'. In this story, Draco gets drunk at a Slytherin party. The author does a great job of showing his more vulnerable side while intoxicated. It's a fascinating exploration of his character outside of his usual stoic self.
One idea could be a story where Scorpius discovers a long - hidden family secret that Draco has been trying to protect him from. It could involve some dark magic from their family's past.
Yes, there are quite a few. You can start by looking on platforms like Archive of Our Own. Some popular ones often explore Draco's character development during this unexpected situation, delving into his relationships with other characters in the Harry Potter universe.
