Agent 33

Agent 33 is a researcher and historian who has a special interest in classical mythology. She had studied the career of Greek Demigod Hercules, and was instrumental by Nick Fury, in recruiting him to aid S.H.I.E.L.D. against Ares and his Warhawks. During Hercules' final battle with the Warhawks, Agent 33 discovered that Agent DePaul was a traitor working for Ares. DePaul attempted to kill Agent 33, but instead died himself. Agent 33's current activities are unknown, but she is presumably still with S.H.I.E.L.D.
