Well, in some fanfictions, Harry Potter might come to own the Ministry of Magic through his heroic deeds. He could have defeated a great evil that threatened the wizarding world so severely that the wizarding community decides he is the most fit to take over and reform the Ministry.
There could be a significant shift in the power dynamics within the wizarding society. With Harry at the helm of the Ministry, the old pure - blood supremacist families might lose some of their influence. This could lead to a more inclusive and progressive wizarding culture. Educational reforms in Hogwarts might also be on the cards as Harry would want to ensure that future generations are well - prepared to face the challenges of the wizarding world, not just in terms of magic but also in terms of ethics and social responsibility.
Perhaps he uncovers some major corruption or inefficiency in the Ministry. So, as a result of his efforts to reform it, he is given control. For example, if he finds that the Ministry has been misusing magic for personal gains, he could lead a movement to take it over and run it in a more just way.
One interesting plotline could be Harry leading a secret resistance against the Ministry's unjust laws. For example, he might gather a group of like - minded witches and wizards to oppose the Ministry's restrictions on Muggle - born rights. Another could be a situation where the Ministry is under the control of a dark force, and Harry has to expose the truth while being hunted by the very institution he once trusted. And there might be a plotline where Harry uses his unique connection with magic, perhaps something related to his connection with Voldemort's magic, to outwit the Ministry's powerful magic - based security systems.
One idea could be exploring the inner workings of the Ministry from the perspective of a new, young employee. They could discover some dark secrets hidden within the various departments.
One idea could be a story where a young witch or wizard discovers a hidden, powerful spell within the Ministry's archives that was long forgotten. This spell could have the potential to either save or destroy the wizarding world, and they must decide what to do with it.
Besides Harry, Hermione is a key character. She can research and find loopholes in the Ministry's laws and regulations. Ron is there too, providing muscle and emotional support. Neville Longbottom could also be involved. He has grown into a strong and brave wizard, and he might join Harry's cause. Additionally, Luna Lovegood with her unique perspective on magic could offer different ways of approaching the conflict with the Ministry. Some fanfictions might also include Sirius Black, if set in a timeline where he didn't die, as he has a history of opposing the Ministry's unjust actions.
He might openly oppose their policies. For example, if the Ministry tries to pass a law that restricts the use of certain spells for self - defense, Harry could publicly speak out against it, giving interviews or writing articles in wizarding newspapers.
One possible reason could be the Ministry's corruption. In the original series, the Ministry often showed signs of being influenced by dark forces or being overly bureaucratic and not seeing the real threats. So in the fanfiction, this might be a driving factor for Harry to oppose them.
A half - veela character who uses her charm to get ahead in the Ministry but then realizes the importance of true merit. She could add an interesting dynamic to the often - stuffy Ministry environment.
