In such a fanfiction, it might be that the baby is more of a symbol of the end of the dark era. The story could show how the very existence of this baby, which is unexpected, causes a shift in the balance of power in the wizarding world. The good characters might try to use the baby's birth as a way to end the reign of Voldemort and Bellatrix's dark ways. For example, they could try to teach the baby love and kindness instead of the dark magic it was born into. This could lead to a series of adventures where the baby's true nature is explored and the wizarding world is saved not by fighting the baby but by redeeming it.
Yes, there are likely some fanfictions out there that handle this concept in a family - friendly way. Some fanfiction authors might explore the idea in a more symbolic or alternate - universe sense, focusing on the implications of such a union in a way that doesn't involve adult or inappropriate content.
It would be very strange and likely a very dark fanfiction. Bellatrix is a Death Eater and Hermione is a good - hearted Gryffindor. The idea of Bellatrix being involved in delivering Hermione's baby goes against their normal character dynamics. It might involve a very convoluted plot where some sort of dark magic or forced situation has led to this scenario.
One common theme is loyalty. Bellatrix is extremely loyal to Voldemort in the original series, and this is often explored more deeply in fanfiction. For example, stories might show her unwavering commitment to him even in the face of great danger.
A prevalent theme is the dark nature of their relationship. It's often depicted as being based on a mutual love for the dark arts and a desire for domination. In some fanfictions, there's also the theme of obsession. Bellatrix's obsession with Voldemort is a central part, like in the fanfiction 'The Darkest Devotion' where her every action is centered around pleasing and serving Voldemort. And of course, the theme of fear also plays a role, as many characters in the wizarding world fear their combined might.
The theme of the dark side of magic can also be prevalent. Since both are dark wizards, fanfictions may explore their use of dark magic together. It could include their experiments with curses, or how they plan to use dark magic to achieve their goals, like taking over the wizarding world. Their relationship might be intertwined with their shared love for the most dangerous and forbidden forms of magic.
In many fanfictions, Bellatrix is often depicted as extremely loyal to Voldemort. She is seen as his most devoted follower, willing to do anything he asks without question.
One common theme is power. Their marriage in fanfiction often revolves around consolidating power in the wizarding world. Since Voldemort is already a powerful dark wizard and Bellatrix is one of his most devoted followers, their union could mean a more terrifying and all - powerful regime. Another theme is obsession. Bellatrix's obsession with Voldemort can be explored in a more romantic or marital context in these stories.
Loyalty is a big one. Bellatrix's extreme loyalty to Voldemort is often explored further. Another is power. Their positions in the dark wizarding world are central to many stories.
There would also be challenges in terms of the baby's protection. Both the Order of the Phoenix and the remaining Death Eaters could see the baby as a threat or a tool. The Order might fear that the baby could be turned to the dark side, while the Death Eaters might want to use the baby's power for their own evil purposes. Harry and Bellatrix would have to constantly be on guard to protect their child.
It would be very strange. It might involve a lot of magic to make such a situation possible in the first place. Maybe there would be a powerful dark spell that forces this situation. And then it would deal with how Harry copes with having a baby that is related to his greatest enemy.
