Another plot could be that Harry is part of a team in the government that is reforming the magical education system. He brings his own experiences from Hogwarts and tries to make changes to ensure that future generations of wizards are better prepared to serve the wizarding community and the government. He might face opposition from traditionalists within the government but still strive to make positive changes.
One possible plot could be Harry using his magical skills for diplomatic relations within the wizarding government. He might be sent on missions to other magical countries to negotiate treaties or resolve disputes.
Well, I'm not sure of a specific 'harry works for the government fanfic' off the top of my head. But you could try searching on some popular fanfic websites like Archive of Our Own. They have a vast collection of fanfictions and you might be able to find one there.
One possible plot could be that they are forced to work together to solve a mystery within Hogwarts. For example, a series of strange disappearances are happening and they are the only two who seem to have some clues. Harry is reluctant but realizes he needs Umbridge's knowledge of the school's inner workings. Umbridge, on the other hand, sees this as a chance to regain some power and status.
One possible plot could be that Hermione does something that Harry perceives as a great betrayal, like perhaps siding with the Ministry when Harry believes they are corrupt. This could lead to a deep - seated hatred from Harry.
Perhaps the fanfic could revolve around Harry Styles using 'camouflage' in a more metaphorical sense. For example, he could be trying to hide his insecurities or past traumas from the public eye. And as the story progresses, someone special might come into his life and gradually help him shed that 'camouflage' and face his real self.
Greyback might be trying to turn Harry into a werewolf. Since Harry is a very powerful wizard, if Greyback could succeed, it would create a werewolf with extraordinary magical abilities. This would be a very dark and dangerous plotline for a fanfic.
One possible plot could be that Harry is experimented on by dark wizards who are trying to create a new form of dark magic. They might use his unique magical abilities as a base for their experiments. Another could be that well - meaning but misguided witches and wizards experiment on Harry to find a cure for a deadly magical disease, thinking his famous resilience could hold the key. Or perhaps some alien - like magical creatures capture Harry and experiment on him to understand the human - wizard form better.
One possible plotline could be that Simon, who might be a powerful figure in the music industry in this fanfic, gets involved with the government somehow. Maybe he has to navigate some new regulations that affect Zayn and Harry's music careers. Zayn and Harry could be facing challenges due to these government - related issues, like restrictions on their concerts or music releases. And their relationship might be put to the test as they deal with these external pressures together.
One possible plot could be that the son is lost in a strange dimension that combines elements of the Harry Potter world and Loki's world. Harry Potter and Loki have to team up to find him. Along the way, they face various challenges like magical creatures from the Potterverse and Loki's enemies. The son, when found, might have developed some unique powers that are crucial for saving both their worlds.
One possible plot could be that Harry is captured by Voldemort and his friends have to mount a dangerous rescue mission. They might have to infiltrate Voldemort's stronghold, which could be filled with dark magic defenses.
One possible plot could be that Lily is under some dark magic influence which makes her turn against Harry. Maybe a powerful dark wizard has corrupted her mind, leading her to believe that Harry is a threat to the wizarding world that needs to be eliminated.
