Harry having ice powers would make the story quite different. In the wizarding world, most magic is more general in nature. Having ice powers would be a very unique and specialized form of magic. He could potentially use his ice powers to explore areas that are normally too dangerous due to extreme heat or fire - based magic. For instance, he could freeze the dragon in the Triwizard Tournament long enough to get the golden egg. His ice powers could also be a key factor in his relationship with Hermione and Ron. Hermione would be eager to research about this new type of magic, while Ron might be both amazed and a little jealous at first. This would add a new layer of complexity to their friendship.
Well, if Harry Potter had sans powers, he might be able to teleport around Hogwarts easily. This would make it much simpler for him to avoid danger or get to his classes on time. For example, when facing Voldemort, he could suddenly disappear and reappear behind him to gain an advantage in battle.
The godlike powers can introduce new conflicts. Let's say a character has the power to rewrite reality. This could cause a rift between them and other characters who fear this power or want to use it for their own evil purposes. Also, if a character has the power of super - speed and strength, they might be able to quickly end battles, but this could also make the story less about strategic planning and more about brute force, which would change the overall feel of the plot. In addition, such powers might make the character an outcast as others are jealous or scared of their abilities.
They can create unexpected twists. For instance, if a character has the power to 'reset time' like in a game, they could go back and change crucial events. Maybe they could prevent Cedric's death or stop Voldemort from ever coming back. This completely alters the original plot's direction.
The fanfiction might change the plot in terms of Harry's relationships. Maybe his new ability with the Nuibari makes some of his friends jealous or in awe of him. Also, it could attract the attention of new characters or factions who are interested in the Nuibari. This could create new alliances or rivalries for Harry. For example, some dark wizards might want to steal the Nuibari from him, leading to new conflicts. And in his journey to master the Nuibari, he might have to visit new places or seek help from unexpected sources, thus diverging from the original plot.
In a Harry Potter fanfiction, the ice phoenix familiar could completely shift the balance of power. If it has the ability to create large - scale ice storms or freeze entire areas, it could be a game - changer in wars or conflicts within the wizarding world. This would force the existing power structures, like the Ministry of Magic or the Death Eaters (if in a relevant time frame), to reevaluate their strategies. Moreover, the presence of the ice phoenix could also attract other magical creatures, either friendly or hostile, which would further complicate the plot.
If Harry is a teacher in a crossover with 'Percy Jackson', he might introduce different ways of using magic that could influence the demigods. This would change the way they approach their quests and battles, as they now have new magical knowledge from Harry.
It adds a new type of creature. The werepire concept changes the magical world by introducing a different kind of threat or ally. Harry might have to face different challenges related to this new entity.
His relationships with the other characters are also altered. Dumbledore, for example, had a big role in Harry's life in the original story. But if Harry is Grindelwald's son, Dumbledore's attitude towards him might be more complex. Dumbledore had a history with Grindelwald, and this new connection could make Dumbledore both more protective and more wary of Harry. The same goes for other characters like Snape. Their interactions with Harry would be colored by this new family connection.
It can change the story by adding new plot elements. For instance, her love for superheroes could lead her to search for magical items that can give her superhero - like powers within the wizarding world.
It changes the original story a great deal. Firstly, Harry's identity is completely different. Instead of being just a wizard, he's now a draconic being. This would change how he approaches challenges. For example, he might use his draconic powers to fight Voldemort instead of just magic spells.
