In some fanfictions, when Harry loses his magic, he could start to explore other aspects of his strength. Maybe he discovers hidden talents that were overshadowed by his magic before. For example, his leadership skills could become more prominent as he has to rely on non - magical means to influence those around him. And he might also develop a deeper understanding of the non - magical world and the people in it.
Well, he might feel extremely lost and confused. He has been so used to relying on his magic for everything. Without it, he could face danger more easily as he no longer has his magical defenses. Also, his friends might have to step up more to protect him.
He could face Morgana's distrust if she takes his secrecy the wrong way. Maybe she'll think he has other motives for hiding his magic from her.
There could be some negative consequences too. Maybe the dragon had some kind of magical protection or was under the care of a powerful wizard or creature. Harry might then face the wrath of those who were protecting the dragon, leading to him having to go into hiding or facing dangerous challenges. Also, the act of killing a dragon, even in self - defense, might make some more sensitive wizards view him in a different, less favorable light.
One possible consequence is that the wizarding world might see Harry as a hero even more than before. After all, dementors are very dangerous creatures, and if he manages to destroy them, it's a huge accomplishment.
One consequence could be that he becomes a hero among the wizarding community. People start to look at him with even more admiration and respect. His reputation as a powerful wizard grows even stronger.
One possible consequence could be a significant change in his fighting style. He might have to rely more on his left side and develop new jutsu techniques that can be executed with one arm. For example, he could focus on enhancing his Rasengan further to compensate for the loss of his right arm's abilities.
Well, he might feel extremely lost and out of place. His identity has been so tied to his magic throughout the series. He could face a lot of ridicule from those who once feared or respected him for his magical abilities. Maybe he'd have to rely on his non - magical skills like his courage and loyalty more than ever.
Merlin could face exile. Uther may not tolerate having a magic - user so close to him.
He might avoid any events or communities related to magic fanfic. He won't be interested in reading or discussing them.
He could lose his friends. In the original story, his friends stand for good and oppose black magic. If Harry starts learning it, they might turn their backs on him. Also, he could be ostracized by the wizarding community. The wizarding world has a clear stance against black magic, and Harry would become an outcast.
One possible consequence could be his expulsion from Hogwarts. Using black magic is strictly prohibited in the wizarding world, and the school has a zero - tolerance policy. Another consequence might be the loss of his friends. His friends, who uphold the values of good magic, might not be able to accept his use of black magic.
