Bae Oh (오배) is Alistair Oh's uncle and was the former leader of the Ekaterina Branch. He is currently in prison in The Hague, Netherlands for various offences, which are listed in a rather comical way in The Black Book of Buried Secrets. He is known as a cheap and lying businessman. It is revealed that he made several alliances with the Lucian Branch when he saw the Trent Family as a growing threat. He also murdered his brother Gordon to become the Ekat leader.
