Barbara Morse's penchant for taunting her opponents in battle earned her the code name "Mockingbird". She was sent on a mission by Nick Fury to stop Carl Delandan; on the way she teamed up with Spider-Man. During this mission, a misunderstanding caused some S.H.I.E.L.D. agents to shoot at her, and she spent some time in a coma. Afterward, she decided to fake the death of her civilian identity in order to keep her family safe.
