There are some. One interesting aspect in some 'Harry Potter Bellatrix mother' fanfictions could be the backstory of Bellatrix's family. Her mother might be depicted as a strict pure - blood witch, and through fanfiction, we can see how that upbringing led Bellatrix to her extreme beliefs. However, the quality can vary greatly among different fanfictions.
No. Fanfics with 'lemon' in the title usually contain adult or inappropriate content, which goes against the family - friendly nature of the Harry Potter series.
It's possible. The Harry Potter universe is so vast and popular that all kinds of unique fanfics are written. Maybe someone has combined it with 'Are You My Mother'.
Since the term 'lemon' often implies something inappropriate in fanfic context, we could instead think about how a proper fanfic about Harry and his mother might focus on her love for him, like how her sacrifice protected him. This could be developed into a story about the lingering influence of her love on Harry's life at Hogwarts.
The themes of love and sacrifice are also quite common. As a mother, fem Harry Potter's love for her family is unconditional. This love often leads to her making sacrifices, whether it's sacrificing her own magical pursuits for her children's well - being or putting herself in danger to protect her family. It's these themes that give the 'fem Harry Potter is a mother' fanfics a lot of emotional depth and make them appealing to readers.
There could be. Fanfiction often takes creative liberties. Writers might come up with a scenario where, through some sort of magic or alternate reality, Harry Potter ends up in the role of Draco's mother. It might involve time - travel or some complex magical spells that rewrite their family ties. However, it's not a common or traditional take on the Harry Potter universe.
It adds a new dimension of care and nurturing. Usually, Harry is seen as a hero, but as a mother, fem Harry can show a different kind of strength. For example, she might use her motherly instincts to resolve conflicts in a more peaceful way instead of through combat.
In some fanfictions, Harry might be described as having his mother's bright green eyes, which were said to be very expressive. Also, he could have her delicate facial features, like a small nose and a soft jawline. Maybe his hair has the same texture as his mother's, which could be a bit wavy.
