They usually show Draco as a character in transformation. Given his past as a somewhat arrogant Slytherin, the pregnancy forces him to re - evaluate his values. He may become more empathetic towards others, especially towards the mother of the child. His pride might take a hit as he has to face situations he never thought he would, like dealing with morning sickness (if the fanfiction includes such details) through magic or non - magic means.
Well, I'm not sure of a specific one, but generally in such fanfictions, they often play with the idea of Draco's character development. Since he was a Slytherin and had a certain reputation in the original series, the pregnancy would be a huge plot twist. Some fanfictions might show him having to balance his Head Boy duties with the physical and emotional challenges of pregnancy. It could also explore how the other Hogwarts students react to this news, like his friends in Slytherin or even his former rivals.
Often, one common theme is the exploration of Draco's character in a new light. Since he's a head boy, it might show his leadership in a different context while dealing with the pregnancy. Another theme could be the relationship dynamics, like how his friends or family react to the situation.
He could be portrayed as a rather embarrassed and frustrated character. Being head boy is a position of pride and respect, and having to deal with the diaper situation would be mortifying for him. He would likely be very secretive about it at first.
In this fanfiction, Draco as head boy might be cursed by a dark wizard. The curse makes him act like a baby at times, including the need for a diaper. As head boy, he has to hide this from most people. The plot could involve his attempts to break the curse with the help of some unlikely allies. He might also learn some valuable lessons about humility and friendship during this ordeal.
I'm not really into that specific genre of fanfiction myself, but you could try searching on fanfiction.net or Archive of Our Own. They have a vast collection of fanfics, and you might be able to find some 'head boy draco mpreg' ones by using their search filters.
There are some fanfictions where Draco and Hermione as Head Boy and Girl are forced to collaborate on a project for the betterment of Hogwarts. In these stories, they learn about each other's strengths and weaknesses. For example, Hermione's vast knowledge and Draco's cunning can combine in unexpected ways. Also, some fanfics explore their relationship development as they have to make decisions regarding student discipline, which leads to some intense and interesting interactions.
They could change Hogwarts by implementing new study programs. Hermione with her love for learning might introduce more advanced and diverse courses. Draco, being from Slytherin, could bring in more practical and competitive elements to the curriculum. Together, they might also work on improving the relationships between the houses, for example, by organizing more inter - house events.
It also gives fans a chance to explore an alternate Hogwarts. In the original series, Hermione and Draco are not in such close positions of power together. Fanfictions allow readers to imagine a Hogwarts where they have to cooperate, make decisions together, and maybe even fall in love. It's like exploring a whole new side of the wizarding world that J.K. Rowling didn't fully show.
In some Draco - pregnant - in - Drarry fanfictions, the plot delves deep into the emotional turmoil of both characters. Draco might be initially scared and ashamed due to his pure - blood upbringing where such a situation is unheard of. Harry, on the other hand, has to deal with his own feelings of being responsible and also facing the potential backlash from their friends and the wizarding society at large. These fanfictions often show a journey of self - discovery and growth for both characters as they navigate this new chapter in their lives.
