One way Hogwarts protects Harry in fanfiction is through its secrets and mysteries. There could be hidden chambers or artifacts that have protective powers. And the loyalty of the Hogwarts students and staff can also create a kind of protective shield around Harry.
Well, he might start by using his knowledge of Hogwarts' secrets and passageways. He could keep an eye on Harry during classes and in the common areas. Maybe he'd also form alliances with other students or teachers who he trusts to help in the protection effort.
In some fanfictions, Fairy Tail characters might use their magic powers to protect Hogwarts. For example, Natsu could use his fire - based magic to fight off dark wizards attacking Hogwarts. His powerful flames could be a great deterrent against enemies.
Percy Jackson could protect Hogwarts by teaming up with the Hogwarts professors. He could offer his unique skills and knowledge. For instance, he could help in guarding the Forbidden Forest using his demigod senses. Also, his sword Riptide could be used to break through any dark magic - created barriers that the bad guys might set up around the school.
One challenge could be dealing with other students who don't understand his over - protective attitude towards Harry. Some might think he's being too nosy or interfering. Another might be that he has his own studies and responsibilities at Hogwarts which could sometimes conflict with his protection duties.
In the fanfiction world, Harry might be the heir to Hogwarts if there was some sort of magical pact made generations ago. For example, perhaps one of his ancestors had a special role in the creation or protection of Hogwarts, and this role was passed down through the family. It could also be that his unique magical abilities, like his ability to resist Voldemort's attacks from a young age, are signs of a deeper connection to Hogwarts itself. This connection could be what designates him as the heir in the fanfiction's plot.
The Avengers could protect Hogwarts in many ways. For instance, Doctor Strange, if he was considered an Avenger here, could use his magic to create powerful wards around the school, stronger than any Hogwarts has ever had. Captain Marvel could fly around the perimeter of Hogwarts, her energy blasts ready to take out any flying threats like dementors or dark wizards on brooms. And the Vision could use his density - changing ability to pass through walls and check for any hidden threats within the castle itself.
Some dark creatures could have magical powers that are not fully understood. They could create barriers or illusions to hide Harry from his pursuers. In the fanfiction, they may also use their knowledge of the dark arts in a positive way to counter the dark magic aimed at Harry. They might be able to sense danger before it arrives and take preemptive action to keep Harry safe.
Another way Harry could deal with it is by getting the support of the Hogwarts faculty. He could gather evidence of the bullying, like spells cast at him without provocation or mean - spirited remarks. Then, he could present this evidence to a trusted teacher, such as Professor McGonagall. She would likely take action against the bullies, perhaps giving them detention or restricting their privileges. This would not only stop the bullying but also show that there are consequences for such actions at Hogwarts.
Well, in certain fanfiction scenarios, Nagini could be magically bound to protect Harry. Maybe a spell was cast that made her loyalty shift from Voldemort to Harry. So she would use her venomous attacks or her stealthy movements to keep Harry safe from Death Eaters or other dark forces. She might also be able to communicate with other snakes in the area and get them to help in protecting Harry.
Well, in fanfiction, Harry could control Hogwarts by being a strong moral compass. Since he has faced so much evil, he would ensure that the school adheres to good values. He might also control it by making alliances with the different houses. By getting the support of Gryffindor, Hufflepuff, Ravenclaw, and Slytherin, he can make decisions and run the school effectively.
