After the New Avengers are forced to allow Osborn to capture Cage when needing medical treatment, the team uses a tracking device Osborn had planted in Luke to trick him into blowing up his own house after rescuing Cage from Osborn's custody. Harry is approached by Norman with the offer of a job within the Dark Avengers. Norman welcomes Harry into Avengers Tower, wanting to make his son into the American Son. When Harry finds a cure for Lily Hollister's Goblin condition for their baby's safety, Lily reveals that it is a ruse to coerce Harry into taking the American Son armor, whom Norman had plotted would die in a tragedy to increase sympathy for Norman and his Dark Avengers. When Lily also reveals that the baby is not Harry's but in fact Norman's, Harry dons his American Son armor, and fights Norman in his Iron Patriot armor. During the battle, Norman declares that Harry is no longer his son, and that he has bred a better child to replace the 'failure' of Harry. After further taunts from Norman, Harry lashes out and defeats his father, declaring "I was never your son!". When Harry has the option of killing Norman, Spider-Man says to decapitate him, since Norman's healing factor may repair a blow to the head. Spider-Man also cautions Harry that killing Norman will cause Harry to "become the son Norman always wanted". Harry instead backs down, and turns away from his father forever. At Loki's suggestion, Osborn creates a rationale to invade Asgard, claiming the world (which was, at the time, positioned at the outskirts of Broxton, Oklahoma) poses a national security threat, by sending the U-Foes to attack Volstagg in Chicago, leading to the destruction of Soldier Field. During a pitched battle with several superheroes, Sentry causes Thor's world to fall to Earth. Osborn fights with the recently-resurrected Steve Rogers, however, Stark removes Osborn's Iron Patriot armor remotely, revealing Osborn used green facepaint to create a goblin-like look. Osborn screams that the Avengers do not know what they have done, only for Spider-Man to knock him down. He tells them they are all dead as the Void is released. Osborn knocks out Rogers and tries to escape, but is captured by Volstagg. Incarcerated in the Raft penitentiary, he blames his Goblin alter-ego for ruining his chance to protect the world. When transferred to a secret underwater government base, Osborn takes steps to ensure his release from prison.
