Rivera was a S.H.I.E.L.D. Agent.
On orders from Alexander Pierce, Agents Hauer and Rivera were sent to the Rat to liberate HYDRA General Werner Reinhardt after forty-four years in prison. After Rivera left the cell, Agent Hauer whispered "Hail HYDRA" to the old man and told him that he was being moved to his old headquarters in Austria.
