After attending a memorial service for Jocasta, recently destroyed battling Ultron, the Avengers are stunned when the long-absent Iron Man telephones and formally quits the group. Elsewhere, at a S.H.I.E.L.D. base on the Chesapeake Bay, Nick Fury and President Ronald Reagan are taken prisoner by doubles who have replaced the S.H.I.E.L.D. agents assigned to the installation. The Avengers are called in and swiftly attack the base, where they discover that the ersatz agents are wooden facsimiles created by the Plantman. Having rescued the prisoners, they must then combat a towering plant-humanoid which has emerged from the bay. Thor, She-Hulk, and Captain Marvel are slowly wearing down their titanic foe when the Avengers' old ally, Eros of Titan, arrives to administer the final blow. Their mission concluded, the Avengers are taken by surprise when Eros boldly declares that he has come to Earth to join their ranks.
