If Harry was replaced with a deer, his grace and speed could play a big role. In the Triwizard Tournament, instead of using magic to get through the tasks, he could use his deer - like abilities. He could jump over obstacles and run really fast. And in the face of danger, like when Voldemort is around, he could use his ability to blend into the forest, since deer are good at camouflage in their natural habitats. This would completely shift the way battles and challenges are faced in the story.
The plot would change a lot. If Harry was a dog, for instance. His loyalty would be even more pronounced. He might be more likely to follow his friends into dangerous situations without question. Also, the way he approaches challenges would be different. Instead of using magic wands and spells, he might rely on his animal instincts like a strong sense of smell to track down things. This could lead to different solutions for the mysteries in the story.
Let's say Harry was a raven. Ravens are often associated with mystery and intelligence. A raven - Harry would be able to fly around Hogwarts and spy on the bad guys more easily. His communication might be in caws and clicks which could be a code that only certain people or animals in the wizarding world could understand. The plot would then revolve around decoding his messages and using his unique perspective from the air to uncover secrets. For example, he could discover hidden passages or the whereabouts of Horcruxes by observing from above.
Well, it could be really interesting. For example, if Harry was replaced with a cat. The cat could have special powers like being able to see things that are hidden from normal view. It could slink around Hogwarts, getting into all sorts of nooks and crannies that a human Harry couldn't. And the way it would interact with other characters would be different too. Hermione might be constantly trying to keep the cat - Harry out of trouble, while Ron might find the cat's antics both annoying and endearing.
In a fanfic where Harry is raised in Brazil, the plot would be vibrant and different. The Brazilian culture is rich in magic - like beliefs already. He could be part of a wizarding community that has a close connection to the Amazon rainforest. His adventures might involve protecting the unique magical creatures there. The plot could also include elements of Brazilian festivals and celebrations, with magic intertwined. His character would be more laid - back perhaps, influenced by the Brazilian lifestyle, which would contrast with the more serious and reserved nature he has in the original story.
It could make him more confident. With the symbiote's powers, he'd feel more capable in dangerous situations.
The puppy would add a lot of fun. Harry would have a new friend to play with. He could take the puppy for walks around the Hogwarts grounds. It would also give him a sense of responsibility outside of his usual wizarding duties.
It would add a whole new dimension to the story. Harry would gain knowledge and skills that are outside the normal Hogwarts curriculum. This could make him more powerful and better equipped to face his enemies. For example, if the goblins teach him about hidden magical defenses, he could use them to protect himself and his friends.
His relationship with Hermione would likely change as she would be both intrigued and worried. She'd probably try to find a logical explanation and a solution right away. Ron, on the other hand, might be a bit more hesitant at first but would eventually come around and see it as just another strange thing in the wizarding world. His enemies, like Draco, might use it as a way to taunt him more, seeing it as a sign of his being different in an even more obvious way.
The relationship between Issei and Sasuke would be very different. Sasuke, used to Naruto's determination to bring him back, would now face Issei. Issei might not have the same emotional connection to Sasuke as Naruto did. Instead, he could be more interested in Sasuke's power. With Sakura, Issei's more flirty nature could make her either annoyed or intrigued, quite unlike Naruto's one - sided love for her.
Well, if they had lived in Harry Potter fanfic, the story could have taken a much more complex turn. Maybe they would have joined Harry in his fight against Voldemort. Their unique skills or knowledge could have given the Order of the Phoenix an edge. For example, if they were really good at potions, they could have brewed some powerful antidotes to the dark magic-induced poisons that Voldemort's followers used. It might also change the relationships among the characters. Harry might have found new friends or allies, which could have affected his decisions and actions throughout the series.
The story would become more intense. Harry would be in a position of power and responsibility. His friends might see him in a different light. For instance, Ron might be a bit jealous at first, but then come to support him. And Hermione would probably try to keep Harry in check, making sure he doesn't abuse his power.
The dynamic between Harry and Hermione would be completely different. Without Ron's comedic relief and his more laid - back nature, the story would be much darker. Harry would lose his best male friend, and this could make him more withdrawn or more determined to avenge Ron's death. Hermione would also have to step up in different ways, perhaps becoming more of a leader instead of relying on Ron's support. The overall tone of the story would be one of loss and melancholy.
