Russia
Russia was a country in many universes.
In the Parallax Universe, during a Cold War caper in the 1980s, Kim acquired a bullet-proof umbrella from a Russian. The umbrella later became one of the items accumulated in the closet of Jenny's apartment. When she and Kim went through the closet to sort its contents, Kim admitted the umbrella was one of hers and explained where she'd got it to Jenny. (PROSE: Cleaning Day)
The 925th Universe's Doctor Know once stated that he hoped Professor Wogglebug hadn't ventured out into any alternative versions of Oz because the Doctor “still ha[s]n’t taught [him] why he should stay away from Russian Oz”.
