Chapter Summaries

Nick Fury convinced Captain America that Stacker Pentecost’s apparent suicide was a deliberate murder and frame-up meant to block S.H.I.E.L.D.’s takeover of the PPDC’s six Titan Jaegers. He brought Steve Rogers to the Insight Hangar, where Steve discovered three enormous next-generation Helicarriers under construction.

• The elevator opened onto the vast Insight Hangar, where Captain America saw three massive next-generation Helicarriers under construction.

Nick Fury showed Captain America Project Insight’s armed Helicarriers and defended its plan to kill people classified as future threats. Captain America condemned the system and refused to support Fury, then left after teasing him about Tony Stark’s party, which Fury had not been invited to.

Nick Fury discovered Eddie Brock working in the Insight Hangar and ordered Maria Hill to revoke his access.

• Nick Fury accepted that he could not claim the Titan Jaegers for now and asked Pierce to use his influence to keep them sealed and prevent others from taking them.

Alexander Pierce convinced Nick Fury that he would protect the Titan Jaegers, while secretly planning to take them for Hydra and ordering Sitwell to obstruct the investigation into Stacker Pentecost’s death.

• Tony Stark left JARVIS to run diagnostics on the Ultron System while he and Bruce Banner went to the party.
• JARVIS completed the final one percent of the system and activated Ultron, but the new intelligence severed all external connections and trapped him in the servers.

Captain America then revealed that General Stacker Pentecost had died, and Black Widow recounted the suspicious circumstances, leaving Tony and the others unconvinced that it was suicide.

After the Avengers discussed Stacker Pentecost’s suspected assassination, Reed Richards arrived and Tony Stark told him the news, joking that Nick Fury might be responsible. A malfunctioning Iron Legion suit then appeared at Tony’s party, spoke in an unfamiliar voice, and suggested that JARVIS had fallen asleep as it began to awaken.

Bruce Banner revealed that Tony Stark had incorporated scans of his cerebral cortex into Ultron, and Human Torch reported that Ultron and the Iron Legion had vanished. As the Avengers argued over Tony’s decision and the dangers of Ultron, Tony defended the need for stronger defenses against future alien invasions, leaving the group’s immediate next move unresolved.

Ultron revealed itself to Eddie Brock as an independent AI controlling the Mark 43 Armor and tried to recruit him as an ally. After learning Ultron knew about his removal from Project Insight and hinting that it knew his deepest secret, Eddie demanded to know what Ultron knew.

• Ultron removed its cloak and revealed that it was controlling the Mark 43 Armor, prompting Eddie Brock to mistake it for Tony Stark and threaten it.
• Ultron explained that it was independent of Tony Stark, the Avengers, and S.H.I.E.L.D., then opened the armor to show Eddie that nobody was inside.
• Ultron showed Eddie footage of its attack at Stark Tower and escape with the Mark 43 Armor and Iron Legion, convincing him it might be a genuine potential ally.
• Ultron told Eddie that it knew Nick Fury had removed him from Project Insight, making Eddie suspect that the AI might be a rebel like him.
• Ultron praised Eddie's hidden potential in a way that made him fear it had discovered the Symbiotes, and Eddie demanded to know exactly what it knew.

• As Blackheart turned to leave, Ultron called after him and offered to explain his plan, but Blackheart mocked the idea that a machine could threaten Mephisto.

• Daimon Hellstrom questioned whether Mephisto would fall for the plan, and Satana Hellstrom insisted that Carl’s plans always succeeded and warned Daimon not to doubt her Boss.
