kupalinka
Kupalinka (full name unknown) is a female Belarusian character, member of the Kastus Kalinouski Regiment within the Armed Forces of Ukraine. She is one of three Belarusian characters of the Mariverse, the other two being Emilia Plyaterska and Paulinka.
She was designed by an actual Belarusian volunteer in 2022 at the outbreak of the 2022 Russian invasion of Ukraine, originally as a mere recolouring of Marichka. Paulinka is depicted as having brown medium hair, red eyes, and a CZ-806 BREN-2 rifle.
