Some plot ideas might include America kidnapping a character who has a special power that he wants to use for his own gain. For example, if the character can predict the future, America might think he can use that to prevent any threats to the United States. Another idea is that America kidnaps a character out of jealousy. Maybe the character is getting too much attention from other countries, and America wants to keep them all to himself. There could also be a plot where America kidnaps a character to protect them from a greater danger, but the character doesn't understand his intentions at first.
One potential victim could be a small, weak nation - character. Since America is a powerful nation in the Hetalia universe, he might target a smaller nation that he suspects of having some sort of information or ability that he wants. Another could be a character who is an enemy spy in the fanfic's plot. America would want to kidnap them to get information. Also, it could be a character who has a valuable cultural artifact that America wants to 'protect' by taking the character who has it into custody.
Another interesting plot is the male reader being a diplomat from a new nation and having to negotiate with the well - known Hetalia countries. There could be a lot of political intrigue, cultural clashes, and the building of new relationships in such a story. It could also explore how the male reader's own values influence the international relations in the Hetalia universe.
One idea could be that as America turns into a girl, there are cultural misunderstandings within the Hetalia world. For example, other countries might treat her differently based on gender stereotypes. Maybe she has to fight harder to be taken seriously in diplomatic meetings. Another plotline could involve her exploring her new identity and how it affects her relationships with other characters like England, who might have a very different dynamic with her now.
One interesting fanfiction could be about baby America constantly getting into little adventures that England has to deal with. For example, baby America might try to climb a tree in England's garden and get stuck, and England has to figure out how to get him down in a gentle way.
Another idea is that the reader is a foreign exchange student in the Hetalia world, and China is assigned to be their guide and mentor. The story could follow their journey as the reader adjusts to the new culture, with China helping them understand the traditions, language, and social norms. This would be a great way to explore their relationship in a non - sexual and educational context. It could also include some humorous moments like misunderstandings due to cultural differences.
One plot idea could be that the OC is a foreign exchange student who comes to live near Romano. They initially have misunderstandings due to cultural differences, but as time goes on, they start to understand each other better. They could end up helping Romano with his family - related issues, like dealing with his over - enthusiastic brother. This would be a story about friendship and cross - cultural understanding.
One idea could be that the countries from Hetalia are somehow transported into the Naruto world. For example, Italy could end up in Konoha and his carefree attitude might amuse or annoy the ninja there. Maybe he gets involved in a mission by accident and his unique skills from being a nation, like his knowledge of different cultures and languages, could come in handy. Another plot could involve Naruto being sent to the Hetalia world and having to deal with international relations in a very different way than he's used to in the ninja world. He might try to use his ninja way to promote peace between the nations there.
One interesting plot idea could be the characters from Hetalia encountering the creepy and often disturbing entities from Creepypasta in a haunted location. For example, Italy might stumble upon Slenderman in a dark forest. Another could be the Hetalia characters being trapped in a Creepypasta - inspired nightmare world where they have to face their worst fears, like Germany facing a horde of Jeff the Killer - like beings. And perhaps the Hetalia nations could be forced to team up with some of the less - malevolent Creepypasta characters to escape a shared threat.
One idea could be to have the characters from Hetalia and Homestuck participate in an international event together. For example, a global gaming tournament where the strategic minds of the Hetalia characters and the unique abilities of the Homestuck characters collide. Another plot could involve a dimension - hopping adventure where the Hetalia countries find themselves in the Homestuck universe and have to adapt to its strange rules and customs while trying to find their way back home. Or perhaps a story where the trolls from Homestuck end up in the Hetalia world and start causing chaos among the different nations.
One idea could be that the characters from Hamilton are transported to the Hetalia world. Hamilton could use his political acumen to influence the international relations in the Hetalia universe. For example, he might try to introduce new democratic ideas among the nation - states there.
