Goliath and Thor in Avengers Mansion face Ultron reborn last issue as Ultron-6 with an indestructible adamantium body. Vision muses how Ultron must have buried instructions in his android brain when he created him, to rebuild him if he was destroyed. Vision retrieved Ultron-5's head after #57 and kept it until he was able to steal adamantium from SHIELD last issue and use the mansion's computers to fashion a new body for his master. He regrets his actions but couldn't avoid doing them.
Iron Man, Wasp and Yellowjacket join the fight. Ultron-6 easily defeats Iron Man because his armour is still weak from last issue, and IM sits out the rest of this issue and the next. Ultron brushes off the rest of the Avengers and leaves the building.
Ultron heads for his old HQ (from #57-58). Vision has guessed where he would go and got there first. The Avengers head there too. And SHIELD sends a contingent to retrieve the adamantium. (Dum-Dum Dugan, Val de Fontaine and Gabe Jones can't join them personally because they are involved in the hunt for Nick Fury in SHIELD #12-14.)
Vision tries to stop Ultron but fails. Ultron claims to be able to control his own form, even though adamantium is supposedly immutable. SHIELD agents disable Vision. Ultron starts a chain reaction that will destroy New York.
