One possibility is that Harry Potter, in this fanfiction, might be exposed to a whole new set of dark magic and powers that demons possess. The demons could see his potential and decide to raise him in a way that is completely different from the wizarding world he knew. Maybe they would teach him to use his magic more aggressively or in ways that are considered unethical in the normal wizarding community.
His character would likely become more edgy and darker. Growing up with demons, he'd be exposed to a lot of negative and cruel things, which would change his view of the world.
Well, in fanfiction the rules are much more flexible. While the main Harry Potter series doesn't have any concept of Harry summoning demons, in fan - made stories, it could happen. For instance, if the fanfiction is set in an alternate universe where the magic is more chaotic and less regulated. Harry could be in a situation where he's desperate and thinks that summoning a demon could solve his problems. It's all about the writer's imagination and how they want to twist the familiar Harry Potter world.
In fanfiction, almost anything can be possible as it's a creative and often unregulated space. However, in the official Harry Potter lore, there is no such thing as summoning demons. Fanfiction might take creative liberties and introduce such concepts, but it would be a deviation from the original magical world created by J.K. Rowling.
It could be a group of lesser - known demons. For example, there might be a demon named Zargoth who has the ability to manipulate time and space a little bit. He could use this power to save Harry from dangerous situations. Another could be Lythra, a female demon with the power of illusion. She can create false images to deceive Harry's enemies.
They're popular because they offer a fresh take on the well - known Harry Potter story. By changing his family situation through adoption, it can completely shift the dynamics of the story.
One common theme is identity. Since Harry is adopted, he may struggle with who he really is in relation to his new family and his wizarding heritage. Another theme could be family dynamics, as he has to adapt to a new family structure. And there's often the theme of secrecy, as his adoption might be something that needs to be hidden for some reason in the wizarding world.
In this kind of fanfiction, Harry often becomes more proficient in potions and other areas that Snape is good at. His relationship with Snape also makes him more empathetic towards Snape's past and the Slytherin house in general. He may not be as quick to judge people based on their house. Also, he might develop a more complex view of the wizarding world's politics, as Snape is deeply involved in some of the darker aspects of it.
Yes, there are quite a few. You can start by looking on popular fanfiction websites like FanFiction.net or Archive of Our Own. Just search for 'Harry Potter Binds Demons' in their search bars, and you'll likely find a variety of stories with different plotlines and interpretations.
In some Harry Potter fanfiction, angels and demons might be portrayed in a variety of ways. For example, they could be used as symbols of good and evil, much like how the concept of light and dark magic exists in the original series. Some fanfictions may create new characters that are angels or demons, who interact with the existing Harry Potter characters in unique ways. They could also be used to explore deeper themes of morality and the battle between good and bad that is already prevalent in the Harry Potter universe.
