Russia, on the other hand, with his more reserved and sometimes mysterious nature, would probably be more introspective. He might be initially shocked but then start to quietly plan and consider the long - term implications. His calm exterior could hide a lot of internal turmoil as he tries to figure out how this situation fits into his world view and his relationship with America.
America's brash and confident personality would likely lead to him initially being in denial or trying to handle the situation on his own terms. He might see it as a challenge to overcome, like he does with many things in the Hetalia series. For example, he could try to come up with some grand, unorthodox solution without really thinking it through.
Another idea is that it could be a deep exploration of their relationship. The pregnancy could be a metaphor for a new level of closeness and cooperation between them. It could start with an accidental situation that forces them to re - evaluate their feelings for each other. As the 'pregnancy' progresses, they learn more about themselves and each other, leading to a transformation in their relationship.
I'm not sure of specific fanfics with this exact combination, but you can try searching on popular fanfic platforms like Archive of Our Own. There are often many Hetalia - related fanfics there. Just use the search terms 'Hetalia', 'Russia', 'female America' and 'pregnant' to narrow down your search.
One possible plot could be about how the two characters deal with the unexpected pregnancy. Maybe Russia is initially shocked but then becomes very protective of fem America. There could be cultural differences in how they approach the pregnancy, like Russia having more traditional views compared to fem America's more modern ideas.
You can start by searching on well - known fanfiction platforms like Archive of Our Own. Use specific tags such as 'Hetalia', 'America', 'Russia' and filter out the ones that seem more in line with your taste, for example, if you want non - lemon ones, exclude the relevant tags. You can also check out fanfiction communities where fans discuss and recommend their favorite works.
There are several great ones. For example, 'The Diplomatic Bond' which focuses on their political interactions and how they gradually build a deeper understanding outside of the usual rivalries. It shows their growth as nations in a non - romantic but still engaging way.
The other Slavic countries would probably be very shocked. Ukraine, for example, might try to mediate between Belarus and Russia. Given their own complex relationships in the Hetalia world, they would want to keep the peace and stability among them.
A third common theme is the personal relationship between the characters. Beyond the political and geopolitical aspects, fanfictions often delve into how Russia and America as characters interact on a personal level. This could involve feelings of mistrust, but also unexpected friendships or alliances. Some stories might explore how their cultural differences play into their relationship, with Russia's more reserved nature compared to America's more outgoing and brash attitude creating interesting dynamics.
In the Hetalia fanfic, America could take guitar lessons from a professional musician or watch online tutorials to start learning.
One common theme is friendship. It shows how America and the South American countries can form strong bonds in the Hetalia universe. Another is cultural exploration, as it delves into the unique cultures of South America from the perspective of Hetalia.
If Gabriel is really intelligent, he might be very methodical in preparing for the baby. For example, he could make detailed plans for Riley's prenatal care and the baby's future. Riley, if she's also intelligent, might be more independent during the pregnancy, not relying too much on others. Their combined intelligence could mean they face any problems during the pregnancy in a very rational way.
