- For the agent in Men in Black: The Series, see Agent X.
Agent X was the chief of the Men in Black during the 1960's, Agent O was his secretary in 1969. Chief X was the head of MIB prior to the arrival of Zed, who apparently replaced X as Director of MiB at some point prior or during the incident related to the Light of Zartha which occurred in 1978, nine years after the launching of the Apollo eleven rocket. X was portrayed by David Rasche, although the role was originally intended for Alec Baldwin[1]. He appears to be slightly discriminatory towards aliens in that he only shows concern for civilian casualties if they are human.
