One big challenge would be trust. Bellatrix has been a loyal Death Eater and has tried to kill Harry many times. Even in pet form, Harry would have a hard time believing she wouldn't turn on him if she regained her normal form. Another challenge would be how others in the wizarding world would react. The Order of the Phoenix might not trust Harry's decision to keep her around, even as a pet.
One way could be through some dark magic gone wrong. Maybe a spell was cast that was intended for something else but backfired and turned Bellatrix into a small, pet - like creature. Harry, being the good - hearted person he is, might feel a sense of responsibility to take care of this new 'pet' while also being extremely cautious due to her past as a Death Eater.
She might be motivated by a long - lost connection. For instance, if there was a family tie between Harry and her that she was previously unaware of. Or perhaps she has a change of heart after seeing the true nature of Voldemort's actions and decides that Harry is the only hope to stop the chaos and destruction Voldemort is causing. It could also be that she is magically bound to save Harry due to some ancient spell or prophecy that she discovers.
Definitely. In the original plot, Bellatrix is a loyal follower of Voldemort and would never be expected to save Harry. But in a fanfic, the author can rewrite the rules. It might be that the fanfic delves deeper into Bellatrix's character, showing that she is not just a one - dimensional villain. There could be a moment of redemption for her, where she realizes that Harry represents something more important than her loyalty to Voldemort, and this realization drives her to save him.
Well, it depends on the specific fanfiction. There are countless fanfictions out there with all kinds of strange and wonderful ideas. Some might indeed depict Bellatrix as Harry's pet. It could be a part of a plot where magic or some other factor has changed their relationship completely. For example, a spell gone wrong or a new magic system introduced in the fanfic could lead to such an odd relationship.
Voldemort is often paired with Bellatrix in fanfiction. Their relationship in the original series was one of master and servant, but in fanfiction, it can be explored in more complex and romantic ways. Another character often paired with her is Narcissa. Their sisterly bond can be a central focus, or it can be twisted into something more sinister or complex in fan - created stories. Also, sometimes Sirius Black is paired with her in alternate universe stories, given their family connection and the contrast in their loyalties.
Many fanfics explore the theme of redemption for Bellatrix. They imagine scenarios where she could have turned away from the dark side. Her complex character, with her madness and loyalty, also makes her a great subject for psychological exploration in fanfics.
There's a fanfic where Bellatrix Lestrange's son is sent away as a baby to protect him from the chaos of the wizarding war. He grows up in a different magical community, unaware of his true heritage at first. As he gets older, he starts to have strange dreams and visions that lead him back to the wizarding world he was born into, and he has to face the truth about his mother.
Well, perhaps Bellatrix discovers a prophecy that involves Harry being crucial for the future of the wizarding world in a way that benefits her own interests in the long run. So, she steps in to save him. It could also be that she has a secret love for Sirius Black (Harry's godfather), and since Harry is related to Sirius, she decides to save Harry out of some twisted sense of loyalty to Sirius.
Bellatrix's character would have to be rewritten to some extent. Saving Harry would go against everything she has stood for in the original story. So, she might become more conflicted, showing both her old, evil self and a new, emerging self that is capable of good. Her relationships with other Death Eaters would also be affected, as they would view her actions as betrayal. This would add a whole new layer of drama and complexity to her character in the fanfic.
