What are some interesting plotlines in 'Harry Potter takes control' fanfiction?

One possible plotline could be Harry taking charge of Hogwarts' security improvements. He might use his unique experiences to set up new magical defenses against the Dark Arts. For example, he could create a network of Patronus guardians around the school, as his own Patronus is very powerful.

One interesting plotline could be that Harry discovers a new, hidden magic that even the most powerful wizards in the wizarding world were unaware of. This new magic gives him an edge in battles against the dark forces. Another could be a story where Harry forms an unlikely alliance with some of the Slytherins to fight a common enemy that threatens the entire Hogwarts.

One possible plotline could be Sirius taking control of a difficult situation within the wizarding world, like dealing with dark wizards. Maybe he uses his skills and knowledge to outwit them.

One great 'Harry Potter Takes Control' fanfiction is 'The Power Within Harry' which shows Harry taking control of his destiny in a unique way. It has him making decisions that are different from the original story, like taking charge of his magical training earlier.

Obviously, Harry Potter is the central character as the title implies. He is the one who is taking control in the story.

Well, in such a fanfiction scenario where the Horcrux takes control, it would be a total chaos. Harry, for instance, if under the Horcrux's control, could turn against his friends. His moral compass, which is usually so strong, would be distorted. The Horcrux might try to use Harry's powers for its own evil purposes, like trying to resurrect Voldemort in a more powerful form or causing destruction within Hogwarts. It would also create a great internal struggle within Harry as he tries to fight against the Horcrux's influence.

If Harry takes control, he would ensure the safety of all students. He has faced so many threats at Hogwarts, so he'd strengthen the security. He might set up new wards and have more regular patrols. And he'd be very strict about the Forbidden Forest, making sure students don't go there without permission.

Perhaps Harry takes control in a way that he unites different wizarding factions that were previously at odds. He could use his influence to promote peace and cooperation among them, leading to a more harmonious wizarding world.

One interesting concept could be the control of magic in new and unique ways. For example, a fanfiction might explore a character having the ability to control the magic of others, which could lead to complex power dynamics within the wizarding world. This could change the relationships between characters like Harry and his friends or enemies. Another concept could be the control of magical creatures in ways not seen in the original series, perhaps using magic to communicate and direct their actions in a more profound way.

One interesting plotline could be about the Founders' initial meetings and how they decided to build Hogwarts. Maybe they had different ideas at first but then came to a consensus on the school's values and layout.
