Character:

Russia is a Yandere character. He is the tallest of all the nations, but has the innocence and cruelty of a child. He adores vodka and sunflowers. His primary target of resentment is General Winter, because despite using the cold to his advantage in war, he is also attacked by him every year. Russia has a kind face, but has mentally cracked from the strain of his bloody history. The other nations are terrified of him, especially the Baltic Trio (Latvia, Lithuania, and Estonia), whom he loves to both physically and emotionally abuse. Occasionally, he stalks others, especially China, while in a panda costume. Russia also has two sisters: his older sister, Ukraine and his younger sister, Belarus. He becomes gloomy and depressed when either of them is on his mind because Ukraine has extremely large breasts (which makes him uncomfortable) and because the sadistic Belarus is obsessed with the idea of forcing him to marry her. She seems to be the only other country which Russia fears. Russia happily promises that eventually "all will become one with Russia". Another favorite phrase is "kolkolkolkol", used when he is angered. Russia is often seen carrying a metal faucet pipe.
