Well, consider a plot where a character believes that the current wizarding world is too chaotic and decides to become a dictator to bring 'order'. They could start by controlling the flow of magic, perhaps by rationing magical items or spells. They might also censor the Daily Prophet and other forms of media to control the narrative. Another aspect could be that they change the education system at Hogwarts, making it more militaristic and less about the exploration of magic for the sake of knowledge. This would create a lot of conflict as the main characters from the original series would likely oppose such a regime.
Well, dictator - themed fanfiction in the Harry Potter universe can be quite a stretch from the original concept. Most fanfiction tends to focus on the heroics and magic within the framework of Hogwarts and the fight against Voldemort. It's possible that such a specific type of fanfiction exists, but it might be a niche and not very common. You could try looking for it by using very specific search terms on fanfiction websites, but I can't guarantee you'll find something good or in line with your expectations.
Perhaps in this fanfiction, Harry becomes a space dictator because he believes that only through strict rule can he bring order to the chaotic and dangerous space. He might use his power to control resources, trade routes, and the movement of different space factions. He could also face challenges from rebels who oppose his dictatorship.
Obviously, Harry would be the main character as the title implies. But other characters like Hermione and Ron would also be important. They could either be part of Harry's regime, reluctantly or wholeheartedly, or they could be part of the resistance against his dictatorship.
One possible plotline could be how Harry's dictatorial rule affects the wizarding society. Maybe he starts imposing strict laws on magic use, which could lead to a rebellion by some wizards who value freedom.
Perhaps there is a female alien diplomat who tries to negotiate with Harry to stop his tyrannical rule. Also, there could be a group of human astronauts who end up in his space domain and have to either submit to his rule or try to escape. Another character could be an old space wizard who has knowledge of a power that could dethrone Harry and is hunted by his forces.
Well, that really varies. Some novels might incorporate a dictator for plot purposes, but many don't. It all comes down to the author's imagination and the story they want to tell.
In Naruto dictator fanfiction, a common theme is the transformation of the hero. Naruto, who is usually seen as a hero, becomes a dictator. This shows how a character's arc can be completely flipped. It might also explore themes of isolation. As a dictator, Naruto would be increasingly alone as more and more people turn against him. This could lead to his further descent into tyranny. Additionally, themes of revenge can play a part. Maybe Naruto becomes a dictator as a form of revenge against those who he feels wronged him in the past, like certain village elders or enemy ninjas. This can create a very dark and complex story.
It's not a common type. In the vast world of Harry Potter fanfiction, you'll find a lot more stories about Hogwarts during different eras, the relationships between the main trio, or the exploration of the wizarding world's politics. 'Breeder fanfiction' is more of a specialized sub - genre that only a small subset of fans might be interested in, as it delves into family - building and genetic - like concepts which are not as central to the general appeal of the Harry Potter series.
