Coulson appears throughout the MCU tie-in comics in supporting roles, acting in the S.H.I.E.L.D. agent capacity that he does in the films.
In Agents of S.H.I.E.L.D., Coulson is revealed to be the S.H.I.E.L.D. agent in charge of Project T.A.H.I.T.I., which was meant to bring a potential dead Avenger back to life using a drug derived from an ancient alien corpse.
