If Batman takes over the world in fanfiction, he might first use his intelligence to restructure society. He'd likely focus on reducing crime everywhere. Gotham would become a model for all cities, with high - tech security and efficient law enforcement.
In this fanfic, Percy is the central figure. However, there might be antagonists too. These could be other powerful individuals or groups who don't want Percy to take over the world. They would try to stop him at every turn, creating a lot of conflict. There could also be some characters who are neutral, just trying to survive in the changing world Percy is creating.
Well, perhaps Percy starts by gathering a group of loyal followers. He might use his unique skills or powers to gain influence in different regions. Then he gradually takes control of key institutions like governments or major corporations.
In this fanfiction, perhaps Stark uses his advanced technology to gain global influence. He might share his Iron Man suits' technology worldwide for peacekeeping, which could lead to him being in a position of de facto world control.
One possible plot could be Hermione using her intelligence to revolutionize the wizarding world's education system in her bid to take over. She might introduce new spells and magical theories that no one has thought of before.
Well, one possibility could be that Ruby starts by uniting all the Huntsmen and Huntresses under her leadership. She might use her unique silver - eyed powers to convince them that she has a vision for a better Remnant. Then, she could begin to reform the kingdoms' governments, making them more focused on protecting the people from Grimm and less on internal power struggles.
In such a fanfiction, perhaps Harry Potter could use his magic to bring about major political changes across the world. He might establish a new global wizarding order where magic and Muggle affairs are more intertwined. For example, he could introduce magical solutions to global problems like climate change, using spells to clean the air or water.
