One possibility could be centaurs. Centaurs are intelligent and have their own code of ethics. They could raise Harry with a deep understanding of nature and the stars, which would give him a different kind of wisdom.
Wolves could be likely. Wolves are known for their strong pack mentality and could raise Harry with a sense of loyalty and family. They could teach him how to hunt and protect himself.
The werewolves are quite popular. Remus Lupin's story has a lot of potential for further exploration in fanfiction. Writers can create more werewolf characters or expand on the werewolf community.
In this fanfiction, the 'Father of Monsters' might be an ancient wizard who has been in a deep slumber for centuries. He was awakened by some disturbance in the wizarding world and, feeling angry about the changes that have occurred, decides to create monsters to bring back what he believes was the 'true' order of the wizarding world. His knowledge of old magic gives him the ability to create extremely powerful and dangerous monsters that no one has ever seen before.
In this fanfiction, it could be that the monsters protect Harry in ways the wizarding world fails to. They might have their own forms of magic or abilities that they pass on to Harry. This could include things like enhanced physical abilities, or the ability to sense danger in a way that normal wizards can't. As a result, Harry becomes a much more complex and powerful character than in the original series.
Monsters can also be used to explore different aspects of the wizarding world's magic. Their unique abilities can lead to new magical theories or explanations in fanfiction. For example, how the magic used to control a certain monster might be related to an ancient and forgotten branch of magic.
Well, depending on what 'rq' stands for, it could be a group of original characters created for the fanfiction. Maybe there's a wise old wizard who takes Harry under his wing as part of this 'rq' upbringing.
Well, Harry Potter is the central figure, but the Weasley siblings are key too. Fred and George could be like his fun - loving older brothers, teaching him all kinds of mischievous spells and pranks. Ginny would be like a sister, and their relationship could develop in a really interesting way. And Percy, despite his differences from the rest of the family, would also be an important character as Harry would be part of the family dynamic that Percy is also a part of.
Maybe it's an existing minor character from the Harry Potter universe who is given a new identity and role as 'gai'. For example, a little - known wizard who has been living in seclusion but has some extraordinary abilities and decides to take Harry under his wing.
Voldemort could still be the main antagonist. He might see Harry's connection to the monsters as a threat to his own power and try to either use it for himself or destroy Harry to prevent him from uniting the monsters against him.
I think Darkseid would be the most unexpected. Imagine Harry Potter being raised in Apokolips. He would have to adapt his magic to survive in such a harsh and evil - dominated place. His magic could potentially be a threat to Darkseid's rule, or he could learn some dark magic - like powers from Darkseid's regime, which would completely change his character and the way he uses magic.
