One reason could be that she's trying to break his will. Just like how people can be broken down by being treated as less than they are. Another reason might be that she has some strange, twisted idea of 'caring' in her deranged mind. She could think that by treating him like a baby, she can control him better, like how you can control a small child more easily than an independent person.
Maybe she wants to humiliate him. By treating him like a baby, she can make him seem weak and powerless.
Well, it could add a really strange and unexpected dynamic to the plot. It might make the story more about Bellatrix's warped sense of power and control. Maybe she's using this 'baby - like' treatment to manipulate Harry in some way, like trying to break his spirit more easily by infantilizing him.
If such a fanfiction exists, it would likely be a very radical re - imagining of the characters. Bellatrix is a villain in the original, and this would completely change her role in a very unexpected way. It might also change the way readers view Harry's early life and the nature of the relationship between the two characters.
One reason could be revenge. Bellatrix might want to get back at Harry for causing problems for Voldemort and the Death Eaters. Kissing him could be a form of humiliation. Another reason could be a power play. By kissing Harry, she shows that she can get close to him and has some sort of control over the situation.
I'm not sure if there is such a specific fanfiction. It's a rather unusual and probably not very common concept within the fanfiction world. The general fanfiction often focuses on more mainstream relationships and storylines in the Harry Potter universe.
Maybe it was a last - minute decision by James and Lily. They might have thought that having Bellatrix as a godmother would offer some kind of protection. After all, she was a powerful witch. Or perhaps there was some sort of old family pact or agreement that made her the godmother.
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.
One way could be through a time - travel or alternate reality plot device. Maybe in a world where dark and light magic collide in unexpected ways, Harry and Bellatrix are forced to work together and somehow, against all odds, a connection forms that leads to a child. It would be a very complex relationship, full of inner turmoil for both characters.
In some fanfictions, Bellatrix might save Harry because she is magically bound to him in some way. Maybe a spell backfired and now she has to protect him. Or perhaps she has a secret love for Sirius Black (Harry's godfather) and in order to honor his memory, she saves Harry. There could also be a plotline where Bellatrix is tired of Voldemort's tyranny and sees Harry as the one who can overthrow him, so she saves him for the greater good of the wizarding community.
Definitely. Fanfiction allows for extreme creativity and bending of the established rules of the original story. The idea of Harry being Bellatrix's son can open up new plotlines, character developments, and explore different aspects of the Harry Potter universe in ways that the original books didn't. It might involve dark magic, alternate timelines, or a re - imagining of the relationships between characters.
Perhaps Draco has developed some sort of complex feelings towards Harry. He could be secretly attracted to Harry and treating him like a baby is a way to get closer to him without admitting his true feelings. Or it could be that Draco has changed as a person and now views Harry as someone who needs his support and guidance, just like one would for a baby.
