First of all, the female characters would be in a state of shock. But then, they would start to adapt. The story could develop as they explore different parts of the wizarding world that were previously male - dominated. For instance, the Forbidden Forest might be seen in a new light as they venture into it without male escorts. They could also find new forms of magic that were hidden or forgotten because they were considered'male' magic. As they do this, they might gradually uncover the mystery behind the disappearance of the males and fight against whatever force is responsible.
The plot could develop with the female characters uniting to search for a solution. They might start by looking into ancient magic that was perhaps created or known only to female witches. Maybe they'd discover that a powerful female dark wizard from the past cast a spell that backfired and made all males disappear. And they'd have to go on a journey to reverse it.
If all the males disappear in a 'Harry Potter' fanfiction, the power dynamics in the wizarding world would shift drastically. Female witches would have to step up to fill all the positions usually held by men. In Hogwarts, female students might start to create new all - female Quidditch teams and adapt the rules. The Ministry of Magic would be dominated by female wizards, and they would face the challenge of not only running the wizarding world but also finding out what caused the males to disappear. Maybe they'd turn to female - only magic like the spells passed down through generations of witches in families.
The plot could develop in a way that the trivot has some connection to Harry's past. Maybe it was something his parents left for him. As he delves deeper into understanding it, he uncovers secrets about his family and Hogwarts. He might have to face some enemies who also want the trivot, leading to intense battles and chases around the wizarding world.
In this fanfiction's plot, Harry's identity as the Boy Who Lived would be intertwined with his military upbringing. He could start a sort of 'wizarding army' within Hogwarts, recruiting students who are willing to fight against the dark forces. His training by soldiers would make him a natural leader in this regard. The story would then revolve around his efforts to build this army, face the opposition from some traditional wizards, and ultimately use this new force to defeat Voldemort in a more strategic and coordinated way.
The plot could start with Harry being born on a spaceship or a space colony. As he grows, he discovers his magical powers, which are different from those on Earth. He then gets a message or a sign that leads him to a quest. This quest might involve finding a lost magical object that has the power to save the space - wizarding community from a dark force. Along the way, he meets other magical beings from different parts of space and they form a team to complete the mission.
The plot could develop with Harry being abandoned in a big Japanese city like Tokyo. He might end up in the muggle part of the city at first and have to use his wits to get by. Eventually, he attracts the attention of Japanese wizards who are both curious and cautious about him. They take him to their magical enclaves where he discovers that there are different types of magic in Japan. There could be political intrigue within the Japanese wizarding community regarding Harry, with some seeing him as a threat and others as an opportunity. He has to navigate through all this while also dealing with his own feelings of abandonment.
The plot could involve Harry using his magic in a more open way around the Dursleys. They might help him hide it from the wizarding world until he's old enough to go to Hogwarts. Then, at Hogwarts, he could be more focused on learning for the joy of it rather than as an escape from his horrible home life.
The plot might start with Harry being taken in by Pitch Black at a very young age. Then, he would be taught things that are not part of the normal Hogwarts curriculum. As he grows older, he might start to question the motives of Pitch Black. This could lead to a conflict between them, and Harry could decide to break away and find his own path in the wizarding world, perhaps with the goal of using his unique skills for good.
He might seek refuge in another house. For example, he could try to convince the Hufflepuffs to take him in. The Hufflepuffs, known for their acceptance, might be his best bet. This could lead to a whole new set of relationships and storylines as he adjusts to a different house environment.
The development could also involve a journey for Harry to understand and control these new Deadshot - like aspects. He might struggle with the more violent nature of Deadshot's skills compared to the wizarding code of ethics. Meanwhile, the wizarding world would be in an uproar as they try to figure out what's happening to Harry. There could be a sub - plot where the Ministry of Magic tries to control or stop Harry from using these un - wizard - like abilities, while Harry has to decide whether to embrace them fully to defeat Voldemort once and for all.
The plot could develop with Harry trying new magical sports or activities. For example, he might discover a new form of broomstick racing that's more dangerous and exciting.
