Maybe Harry uses his wolf abilities to track down an enemy in the forest. His enhanced senses, like his sense of smell as a wolf, would be really useful for that.
Sure. One example could be that Harry is able to understand ancient runes and spells without any formal training. He just looks at them and immediately knows what they mean and how to use them. Another could be that he has an inborn ability to communicate with magical creatures in a way that no one else can, and he uses this to gain their help in battles or to solve problems in the wizarding world.
In this fanfiction, Harry could be a player in the sense of being a political player within the wizarding world. He might be secretly forming alliances with different wizarding families to gain power and influence. He uses his status as 'the boy who lived' to his advantage. In relationships, he could be a bit of a heartbreaker. He goes on dates with Hermione, Ginny, and other girls, but is never fully committed, causing some drama and tension among his friends and the girls themselves.
Perhaps she might accidentally set off a series of magical explosions in the Hogwarts corridors while trying out a new spell she made up on the fly. This would lead to chaos as students and teachers scramble to figure out what happened and how to fix the damage.
Maybe her mutant ability is telepathy, which could make her really good at reading the minds of her enemies in the wizarding world. This could help her solve mysteries or avoid dangerous situations. At the same time, it could also cause problems if other wizards find out she has this power, as it might be seen as an 'unfair' advantage or something dark.
In a group setting within the fanfiction, Hermione could be the one who follows the group's consensus rather than always being the one to drive the ideas forward. Maybe she's part of a magical society where she has to abide by the rules set by those in more dominant positions, and she's in a submissive role in relation to those power structures. This could lead to her having to navigate her own beliefs and desires within the constraints of this sub role.
Perhaps Percy has to compete in Roman gladiator - like games.
Perhaps in this fanfiction, Naruto is an alpha in terms of his social standing among the ninja villages. He could be the one who always gets the first pick of missions and resources because of his alpha status. Also, in his relationships, he might be more dominant. For example, in his friendship with Sasuke, he could be the one who always makes the final decisions on their joint adventures.
Maybe Naruto gets sent to a far - away land by some mysterious force and has to find his way back. This could involve him facing new enemies and making new allies that are completely different from those in the original Naruto story.
Well, there are many possibilities. Naruto could find that his vizard powers allow him to communicate with spirits in a new way, which could help him in his ninja missions. He might also face internal conflicts as the Hollow part of him tries to take over during intense battles. His vizard powers could attract the attention of powerful villains who want to either control him or steal his powers. He may have to train with a new mentor who is familiar with vizard powers to fully master them. And perhaps he uses his new powers to create a new type of jutsu that combines ninja techniques with vizard abilities.
Maybe Bella, as a hybrid, can run faster than normal vampires in the story. She could use this ability to save other characters from danger.
