A child who was left for dead at the age of 3, adopted into a secret organization that produced assassins for countries. The country that adopted him was Russia. So far, he has been on hundreds of missions and killed thousands of people. Now, since no countries exist, he lives day to day and kills anyone who poses a threat. Oleg was put into a group known as Killijuro and was raised to be an assassin. He was trained in the art of stealth and killing. When adopted by Russia, he was put to work which contributed to the eventual cause of the world's destruction. He has no family and no loved ones. He once had a brother, but lost contact with him post-Apocalypse.
