North Korea
Kim Jong-un of the Kim dynasty is the current Supreme Leader or "Suryeong" of North Korea. He heads all major governing structures: he is Chairman of the Workers' Party of Korea, Chairman of the State Affairs Commission of North Korea, and Supreme Commander of the Korean People's Army. His grandfather Kim Il-sung, the founder and leader of North Korea until his death in 1994, is the country's "Eternal President", while his father Kim Jong-il who succeeded Kim Il-sung as leader was announced "Eternal General Secretary" after his death in 2011.
O Jin-u
Marshal Oh Jin-Woo (March 8, 1917 – February 25, 1995) was a soldier and politician of North Korea. He was the Minister of Armed Forces for many years until his death in February 1995. Oh was the third most powerful person in North Korea, after Kim Il-Sung and Kim Jong-Il (therefore the most powerful person that possessed no blood relations to the Kim family). Very little is known about him except for the fact that he served with Kim Il-sung's partisan unit and eventually rose through the ranks of the North Korean Army. He distinguished himself during the Korean War and was a trusted adviser of the North Korean leader until his death, also being his chief guard in 1945.
