Polandball is the original protagonist of polandball. He can't get anything in space according to the meme, even though there was a Polish cosmonaut, Miroslaw Hermaszewski. Poland is the country where vodka was invented.
This character is often portrayed as a naive countryball often bullied by his neighbours for partitions or annexations. Usually, he's a plumber for UKball, based on the fact that many Poles live in Great Britain. Both Germanyball and Russiaball sometimes see Polandball as a possible expansion territory.
