Recently, I saw the picture of Korea at the Character pages(http://hetalia.wikia.com/wiki/List_of_Hetalia:_Axis_Powers_characters), and I wanted to say, that that isn't official art anymore. This design of him is by Himaruya removed from the site due controversy. The South korean government judged it as very offensive. Please, use another picture for Korea. He didn't make an appearance at the anime, but he maked an very short appearance at Marukaite Chikyuu.
P.S: I would like to help with making the character pages.
