The Asian Prison Thug is a prisoner in the Bhutanese prison that Bruce Wayne is located in at the beginning of the film.
In prison, Bruce Wayne is warned by an aged prisoner that the others are planning on killing him. When he is about to have breakfast, a very imposing thug slams his tray down and tells him "You are in hell little man! And I am the devil!" before throwing a punch. When Bruce responds that he is only practice, the prisoner charges at him. After a short exchange of punches, he is swiftly knocked down.
