There could be a plot where Harry's upbringing at Hogwarts affects his relationship with the other students. He might be seen as an insider by some, but also an oddity by others. This could lead to some interesting dynamics, such as rivalries or unexpected friendships. For example, he might have a closer friendship with the students from different houses as he doesn't have the same house - based prejudices that other students have.
One interesting plot could be Harry becoming an Auror and facing new dark wizards that emerge post - Hogwarts. He uses his skills learned at Hogwarts to protect the wizarding world in a more complex and dangerous environment.
One interesting plot could be an apprentice discovers a long - lost magic spell in the Hogwarts library. This spell has the power to control the weather within the school grounds. The apprentice then has to figure out how to use it responsibly while facing challenges from other students who want to use it for mischief.
One interesting plot could be how Harry's magical abilities are discovered in a biker community that has no prior knowledge of magic. Maybe he accidentally makes his bike levitate during a race or something. Another could be how the bikers protect Harry from the dark forces that are after him, using their tough - as - nails attitude and street - smart skills instead of magic. And there might be a plot where Harry tries to introduce the bikers to the wizarding world in a really comical way.
One interesting plot could be Harry being raised by a pack of wolves. He might learn their ways of survival, like hunting and communicating through howls. This would give him a very different set of skills compared to his wizarding upbringing in the original series.
One interesting plot could be Harry developing unique magical abilities due to his upbringing among spiders. For example, he might be able to communicate with spiders in a more profound way than just Parseltongue, and use this to his advantage in dangerous situations.
Well, one possible interesting plot could be how Harry's magic develops in a different way under the influence of the Veela. Maybe his spells have a unique flair or he has an enhanced connection to certain types of magic. Another plot could involve the Veela's culture and how Harry adapts to it while growing up. For example, their social norms and traditions might shape his view of the wizarding world.
One interesting plot could be that the OC (original character) has a unique magical ability that they pass on to Harry. For example, the OC might be able to communicate with magical creatures in a way no one else can, and they teach Harry this skill. This could lead to Harry having a whole new set of allies in the magical world.
One interesting plot could be that Harry, being raised by Raven, might have a different understanding of magic from the start. He could be exposed to more esoteric and ancient forms of magic that Raven might know. This would give him an edge in his Hogwarts years.
Well, perhaps a plot where Harry has to defend the bears from dark wizards who want to harm them for some reason. Since he was raised by bears, he would have a deep connection with them and would do anything to protect them. He might use his unique knowledge of the forest, gained from living with the bears, to outwit the dark wizards.
Well, in some of these fanfictions, Harry might be raised with a different set of values. Maybe he becomes more attuned to a certain magical aspect that was overlooked in the original series. For example, he could have a stronger connection to magical creatures if his 'rq' upbringing emphasizes that.
