August Durant was a physicist and United States agent who was exposed to a deadly experimental virus. A covert government group called The Agency bartered with Durant, offering him an antidote to the virus in exchange for his unquestioning support. Durant agreed and, as directed by The Agency, assumed the identity of Mockingbird and formed the first Secret Six.
Durant soon disband the Secret Six and later learned that The Agency was developing an even deadlier version of the virus that he was afflicted, and withdrew his support of the group. Durant reassembled the Secret Six and asked them to train a new team. Unfortunately, The Agency punished Durant's defiance by arranging his and his teammates deaths in a plane crash.
