Who could be the potential allies of the Demons Child in a 'Harry Potter and the Demons Child' fanfic?

One idea could be exploring the relationship between the new character, the Demons Child, and the existing Hogwarts students. Maybe the child has unique powers that both intrigue and frighten others.

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.

Maybe the demon's soul itself could be the main antagonist in a way. It has its own will and desires, which are mainly to spread chaos and destruction. It could possess other characters in the story and make them act against Harry. For instance, it might possess a Hogwarts professor who then tries to undermine Harry's efforts to stop it. The demon's soul's ability to manipulate and corrupt would make it a very dangerous and menacing antagonist.

The Weasley family, if they found out about Harry's situation. Ron, being his best friend, would surely want to help. They could bring him food and supplies. Also, Dumbledore, in his mysterious ways, might be looking out for Harry from afar and send some help in the form of magical objects or even magical creatures to protect him.

Well, it could be about Harry Potter having to face a new kind of dark magic related to the demon's soul. Maybe he discovers a hidden artifact that is infused with the demon's soul and has to figure out how to destroy it without getting corrupted himself.

Iruka could be a potential ally. He has always had a bit of a soft spot for Naruto. Even in the face of Naruto being neglected, Iruka might step up more and offer more than just basic support. Another could be Shikamaru. He is smart and might see the value in Naruto that others are missing. He could help Naruto strategize to get out of his neglected situation.

Hermione could be a potential rescuer. In a different timeline or scenario, she might stumble upon the abandoned Harry and use her intelligence and knowledge of magic to take care of him. Another could be Hagrid. He has a big heart and a love for all things magical. He might find Harry and take him under his wing, protecting him from any harm. And Sirius Black is also a possibility. Even if he was wrongly imprisoned, if he escaped earlier, he could be the one to rescue Harry and keep him away from the Dursleys.

If Harry summons demons in fanfiction, he could face immediate danger. Demons are often depicted as malevolent entities. They might attack Harry instead of doing his bidding. He could also lose control of the situation, leading to chaos around him. His friends might turn against him when they discover what he's done, seeing it as a step into the dark side of magic.

Another antagonist could be a group within the ninja village itself. Maybe they fear the changes that the child of prophecy might bring. They could be the more conservative elements who don't want to see new ideas or powers emerging. They might try to undermine the child's training or spread false rumors about them. For example, they could claim that the child is a danger to the village, turning public opinion against the child.

It could be a new dark wizard who is jealous of Harry Potter's fame and success. This dark wizard targets Harry's child, thinking that by causing trouble for the child, they can somehow diminish Harry's reputation in the wizarding world. He might try to frame the child for various dark magic incidents around Hogwarts.
