When Johnson's mother was killed, he returned to the U.S.A to be with his friend. But Johnson was the target of Orion to use his blood to regain his immortality, revealing Johnson as the son of Nick Fury. Coulson helped his friend in destroying Leviathan, and was made an Agent of S.H.I.E.L.D. alongside him. He later joined S.H.I.E.L.D.'s Secret Avengers initiative, and was responsible for the recruitment of its first members. Months after joining S.H.I.E.L.D., Coulson became their supreme commander for Special Ops. In one of the team's first big missions, he faced off against Dormammu to prevent humankind from turning into Mindless Ones. He subsequently freed Doctor Strange from Dormammu's imprisonment, after Strange had helped Coulson put together the pieces in order to find out about Dormammu's secret mission.
