Well, sometimes in these fanfictions, Draco hides his pregnancy because he's in a secret relationship. For example, if he's in love with someone from a different house or a different social standing. He might be afraid that if his pregnancy is discovered, the relationship will be exposed and there will be consequences. Also, there could be a plot where he discovers some magical mystery related to his pregnancy that makes him think he has to hide it, like there's a prophecy or some dark magic involved.
Draco and Hermione is also a pairing that shows up in these types of fanfictions. Given their different backgrounds and the initial animosity between them in the original story, Draco hiding his pregnancy from Hermione can lead to a complex story. It could involve Hermione slowly finding out and having to deal with her own feelings about Draco and the situation. There's also the pairing of Draco with a random Muggle, which can add a whole new layer as he has to hide it not only from the wizarding world but also from the Muggle's family and society.
It could be Death Eaters. They've always been after Harry in the original series, so in this fanfiction, they might be hot on his trail again, forcing him to seek refuge in the power station.
In the wizarding world, Hermione was overjoyed to share the news. She took out her wand and enchanted a parchment to display the words 'We're expecting!' with little magical stars around it. Harry and Ron were the first to be informed, and their faces lit up with huge smiles. The news quickly spread through Hogwarts, and everyone was excited for the new addition to the wizarding family.
Obviously, Harry Potter is the main character as it's about him hiding his power. His friends, like Hermione Granger and Ron Weasley, are also likely to be main characters. They might be in the dark about his hidden power at first, which could create some interesting dynamics in their relationships.
Maybe Harry is on the run from some dark forces and he finds the power station as an unexpected hiding place. He could be using the complex structure and machinery of the power station to evade detection, perhaps with some magical twists like using spells to blend in with the electrical currents or machinery.
Yes, there might be some out there in the vast world of fanfiction. However, this is a rather dark and uncanonical topic for the 'Harry Potter' universe. J.K. Rowling's original works don't touch on such issues, but in the realm of fanfiction, some writers might explore extreme or different scenarios. But it's important to note that this kind of content can be quite controversial as it goes against the generally positive and magical tone of the original series.
Harry could enlist the help of some of his most trusted friends like Neville and Ginny. Neville could use his knowledge of Herbology to create magical plants that act as sentinels around the hiding place. Ginny, with her powerful magic, could help set up wards. Together, they form a sort of protective circle around Hermione and Luna. Also, Harry might use his Invisibility Cloak to move around undetected when getting supplies for them.
For creativity. It's a unique twist on the original story. It allows the author to explore different relationships and how characters would react if Harry had a different gender presentation.
Well, one possible plot could be that Harry hides his power to protect his friends from dark wizards who might target them if they knew how powerful he really was. Another could be that he hides his power to secretly investigate a mystery within Hogwarts without drawing attention.
