They are both countryhumans, and both male. They were both basically personifications of countries. They were humanoid shape, and people made a lot if fanfic and art of them, they had the colour of their flag as the colour of their body, example: USSR’s flag is red so his body would be read with the little sickle and hammer symbol on his face. Countryhumans were always given a specific stereotype that would match their country. USSR was 41. And Russias ‘friend’ America, was 19 too and is a girl.
