Another aspect is his friends. He'd probably make friends with Canadian wizards and witches. Their values and the things they care about could be different from those in the UK. For example, they might be more concerned with the magical creatures native to Canada, like the Thunderbird. This would influence Harry's adventures and the things he gets involved in.
Well, one major plot change could be his relationship with magic. In Canada, the magical community might have different traditions. Maybe the way magic is taught in Canadian wizarding schools is more nature - based compared to Hogwarts. So Harry would grow up with a different understanding of magic.
One possible plot could be Harry growing up believing he is on the right side by following Bellatrix and the Death Eaters. But then he discovers some secrets about his real parents and starts to question everything he's been taught. This leads to an internal struggle as he tries to decide whether to stay with Bellatrix or break away and find his true identity.
If Harry dies instead of Cedric in fanfic, Hogwarts would be in a state of deep mourning. The entire wizarding world that had placed so much hope in Harry would be in shock. Voldemort would likely face less opposition in the short term as Harry was seen as the main threat to his return. Friends like Ron and Hermione would be devastated, and they might have to take different paths. Ron could become more withdrawn, and Hermione might focus all her energy on finding a way to avenge Harry. The story would also likely shift focus to Cedric, who would now carry the weight of the prophecy or the task of ultimately facing Voldemort, if there was such a concept in this altered universe.
One possible plot twist could be that Harry Dresden's magic system clashes with the wizarding world of Harry Potter. For example, Dresden's more rough - and - tumble approach to magic might get him in trouble with the Ministry of Magic. Another could be that Harry Potter, being raised by Dresden, develops a very different personality. He might be more street - smart and less naive compared to his original self. Also, there could be a plot twist where the enemies from Dresden's world start targeting Harry Potter because of his connection to Dresden.
Perhaps a major plot twist could be that the values instilled in Harry by the Nathrezeim are not as dark as everyone expects. He might bring a new perspective to the wizarding world, one that challenges the traditional view of good and evil. For example, he could show that there are shades of grey in magic and relationships, and that not all associated with the Nathrezeim are purely evil.
One possibility is that Harry grows up in a more refined and magical environment. The Delacour family might introduce him to different aspects of French magic. He could be trained in unique spells and magical traditions. Also, he might have a different relationship with the magical community, perhaps being more involved with international magical relations from an early age.
One possible plot could be that the soldiers instill in Harry a sense of discipline and combat skills from a young age. He might grow up with a military - style routine, which would make his Hogwarts experience very different. For example, he could be more organized in his studies and dueling, approaching them like military strategies.
One possible plotline could be that Harry grows up with a very different set of values. Since Lucifer is often associated with rebellion and a certain kind of dark knowledge, Harry might be taught to question authority in a more extreme way than in the original series. He could also have some very unique magical abilities that are influenced by Lucifer's nature, perhaps abilities related to darker forms of magic.
One possible plot twist could be that the Dragon Slayer's combat skills and no - nonsense attitude influence Harry in unexpected ways. Maybe Harry becomes more physically aggressive in his defense against the Dark Arts, rather than relying solely on magic. Another twist could be that the Dragon Slayer has secrets about Harry's parents that even Dumbledore doesn't know, leading to a whole new understanding of Harry's heritage.
One possible plot twist could be that the Malfoy twins, being raised in a pure - blood supremacist family, initially try to indoctrinate Harry with their beliefs. But as they grow up together, they start to question their family's ideology due to Harry's influence. Harry, on the other hand, might struggle with the Malfoy name attached to him, yet find unexpected support from the twins in his journey to discover his true identity and magic capabilities.
The plot might involve Harry being taken to the Demon World at a young age. There, he'd be raised among demons. Hiei would likely be a strict mentor. Harry would have to learn to survive in a cut - throat environment. His magic could blend with the demon powers in unique ways. For example, his Patronus could take on a more demonic form.
