For those unaware, he personifies the Union of Soviet Socialist Republics, commonly referred to as the Soviet Union or the U.S.S.R. He originates from a group known as countryhumans, which operates on the principle of utilizing fan-created headcanons.
The majority of his behaviors are inspired by my personal headcanons about him. You're welcome to adapt his character sketch to craft your interpretation of the Soviet character; I'm indifferent, so unleash your creativity.
