un-stable-mother

Russia is a modestly-dressed woman with long beige-blonde hair. Her first seen picture gave her soft blue eyes while her second appearance gave her lilac colored eyes.
Himaruya has described her personality as akin to a wearied mother figure who is emotionally unstable rather than childishly cruel. Her fanon human name is Anya Braginskaya. Anya is a Russian diminutive of Anna. In a blog post, Himaruya said he liked Russia's fanon name. The first color sketch featuring her depicted her in a blue dress, while a "chibi" picture of her shows her to wear a long pink winter coat.

Instead of a lead pipe, she is seen with a large shovel and matryoshka dolls.

Kolko is a nickname for the female version of Russia, derived from the suffix "-ko" and "Kol" (from Russia's chant Kolkolkol, in reference to the kolkhoz). She is also sometimes referred to as Roshiko, deriving from Roshia and the suffix "-ko".
