One significant event could be when Harry decides to leave Hogwarts temporarily to train with a reclusive but powerful wizard. This step shows his determination to take control of his magical growth and not be confined to the standard Hogwarts education. It's a big decision as it goes against the norm and he risks a lot, but it also gives him the opportunity to learn things that can help him better face Voldemort or other threats.
The element of breaking free from expectations is crucial. In the original story, there were a lot of expectations placed on Harry. In fanfic, he can shatter those. For example, if the wizarding world expects him to be a certain kind of hero, he can redefine what that means. Also, the development of his own magical style is important. He doesn't have to use the same spells as everyone else. He can create his own signature magic, which shows his control over his life and his magic.
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.
In the 'Harry Takes Control of His Life Fanfic', he could be facing challenges that force him to take charge. For example, a new dark threat emerges and he decides to form his own group to combat it instead of relying on the existing Order of the Phoenix. He might also take control of his own emotions, like dealing with his anger towards Snape in a more assertive and mature way.
Obviously, Harry would be the main character. He is the one taking control of his life. Hermione and Ron would most likely be important characters too as they are Harry's closest friends and would be involved in his journey. Dumbledore could also play a role, perhaps as a mentor figure that Harry starts to question and break away from as he takes more control.
Another way is through self - discovery. In fanfiction, Harry might spend more time exploring his family history on his own, not just relying on what Dumbledore or others tell him. By uncovering secrets about his family, he could find hidden powers or knowledge that empowers him to make his own decisions and take control of his destiny rather than being pushed around by the events around him.
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.
One interesting plotline could be Harry Potter taking control of Hogwarts' curriculum. He might introduce new and more practical magic courses. For example, he could start a course on modern magical defense against dark forces in the wizarding world today, which includes dealing with new threats like dark wizards using Muggle technology in their spells.
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.
