He could accidentally cause harm to those he controls. Maybe he doesn't fully understand the power and makes people do things that are against their nature, which could have long - term negative impacts on their mental states. Moreover, the wizarding world might see him as a threat and try to limit or stop his power, leading to a lot of conflict.
One consequence could be that he loses the trust of his friends. They might be afraid that he could control them at any time.
In the fanfiction, if Harry has this power to control people, he might become overconfident. He could start to believe that he can solve all problems by controlling others instead of using his normal skills and intelligence. This over - reliance on the power could lead to his downfall. Also, the power could be misused by others if they find a way to take it from him, creating chaos in the wizarding world.
He could face legal issues within the wizarding world. There are likely laws against using magic to control others without their consent. So, he might find himself in front of the Wizengamot, facing serious charges. This would not only damage his reputation but also put his future at Hogwarts and in the wizarding community in jeopardy.
He might attract the wrong kind of attention. Evil ninja or dark organizations could see him as a valuable asset or a threat. They might try to either recruit him or eliminate him. This would put Naruto in a lot of dangerous situations, constantly having to defend himself against these new enemies.
One potential drawback could be the moral implications. Controlling someone else's blood is a very invasive and potentially cruel ability. Naruto, who is known for his kind heart, might struggle with using such a power. Also, it might be difficult to control precisely, and he could accidentally harm allies if he's not careful.
There could be various consequences. Firstly, a cease - and - desist order might be issued, forcing the seller to stop selling the fanfiction immediately. Secondly, the seller may have to pay damages. Since 'Harry Potter' is a very valuable brand, the damages could be substantial. And thirdly, in some cases, there could be criminal charges if the infringement is severe enough, although this is less common in cases of fanfiction sales.
Well, it could change the whole dynamic. He might use it to manipulate enemies, like making Voldemort's followers turn on him. This would speed up the end of the war perhaps.
One potential consequence could be disrupting the natural balance of water - based magic. If he teleports too often or without proper control, it might cause ripples in the magical ecosystem of water bodies. Another consequence could be attracting unwanted attention from water - dwelling magical creatures. They might see his teleportation as an intrusion or a threat.
The wizarding economy would be in chaos. Gringotts is the central bank of the wizarding world. Its destruction would mean that people's savings, vaults, and all the financial transactions would be disrupted. Wizards and witches would lose their trust in the financial system.
One potential consequence is a high risk of unplanned pregnancy. When there is no form of birth control and a lot of sperm present, the chances of fertilization are much greater. This can lead to various challenges for the individuals involved, such as changes in life plans, financial stress if not prepared for a baby, and potential strain on relationships.
One potential consequence could be a change in his relationships. His friends might be worried or even turn against him. For example, Hermione, who is always concerned about following the rules and doing what's right, would likely be very troubled. Another consequence could be a shift in his own moral compass. The dark arts are often associated with negative and unethical actions, so he could start to make more morally ambiguous decisions.
If Harry summons demons in fanfiction, he could face immediate danger. Demons are often depicted as malevolent entities. They might attack Harry instead of doing his bidding. He could also lose control of the situation, leading to chaos around him. His friends might turn against him when they discover what he's done, seeing it as a step into the dark side of magic.
