In many fanfictions, Harry might use his special connection to Hogwarts. Since he has a deep bond with the school, he could simply will the defenses to activate, like a form of magic that comes from his heart.
Some fanfictions depict Harry using his unique magical abilities, such as his ability to speak Parseltongue. Maybe there's a hidden snake - related mechanism for the defenses, and by using Parseltongue, he can unlock and activate it. Or he could be using his Gryffindor courage and intelligence to figure out complex magical puzzles that are linked to the activation of Hogwarts' defenses.
Often, it's through his discovery of hidden spells or magical artifacts within Hogwarts. For instance, he could find a long - lost wand or a magical rune that is the key to activating the defenses. He might also get help from the ghosts or portraits in the castle, who guide him to the necessary steps to turn on the defenses.
Another possibility is that his connection with the Sorting Hat plays a role. The Sorting Hat has a deep knowledge of Hogwarts and its magic. If Harry were to have a special conversation with the Sorting Hat or if the Hat were to bestow some sort of power upon him, it could enable him to activate the wards. After all, the Sorting Hat has been known to recognize and respond to the qualities and needs of the students at Hogwarts.
In some fanfictions, it could be by accident. Maybe he casts a spell that interacts with the wards in an unexpected way. For example, if he tries a new spell he learned outside of Hogwarts and it has a frequency that matches the activation code of the wards.
In some fanfictions, when Harry activates Hogwarts' defenses, it might lead to a strengthening of the protective spells around the castle. This could prevent dark wizards from entering easily, like creating an impenetrable magical barrier.
He might use his superhuman strength and speed, which he has as a demigod. With his enhanced physical abilities, he can easily take on many foes at once. And his power over water is a huge advantage. He could use water to create distractions or directly attack the villains.
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.
Harry could change Hogwarts in fanfiction through his leadership. He might inspire the students to be more united and inclusive. For instance, he could start a club or organization that focuses on helping students from different houses interact better, breaking down the traditional rivalries between Gryffindor, Slytherin, Hufflepuff, and Ravenclaw.
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.
In fanfiction, Harry might use his knowledge of the secret passages in Hogwarts to hide from Dumbledore. He could also use Polyjuice Potion to change his appearance and blend in with other students or people in the wizarding world. Sometimes, he could even ask his friends to create distractions so that he can slip away and hide. For instance, Ron and Hermione could start a commotion in one part of the castle while Harry hides in a different, more secluded area.
In fanfiction, Harry Potter can change Hogwarts in a multitude of ways. His unique position as the Boy Who Lived gives him a certain influence. He may use his fame and power to bring about changes in the curriculum. For example, he could push for more practical defense against the dark arts training, considering his own battles. His relationships, like his close bond with Hermione and Ron, could also lead to changes. They might start study groups or clubs that become popular at Hogwarts, changing the extracurricular landscape. Moreover, his encounters with different magical creatures could result in new courses or research areas at Hogwarts. All these elements contribute to the transformation of Hogwarts in fanfiction.
Hogwarts helps in fanfiction by bringing characters together. Students from different backgrounds and with different abilities meet at Hogwarts. This interaction can lead to friendships and alliances. For instance, two characters who might not have otherwise met could team up to fight a dark force threatening the school. The school also offers a sense of protection. The wards around Hogwarts keep out many dark creatures and wizards. In fanfiction, this protection might be crucial for a character who is being hunted. It gives them a safe haven to hide and grow stronger.
