Synopsis
This issue picks up from the end of #18 rather than #19, with renegade SHIELD scientist Carolina Washington at AIM HQ putting her case before the triumvirate of Norman Osborn, Madame Hydra and Superia, leading a combination of AIM, Hand, HAMMER and Hydra, under the overall name of HAMMER.
Osborn suggests that Washington and Dr Wentworth (ie Superia) might be able to rid Madame Hydra of the octopoid headpiece that is keeping her alive.
Then the issue syncs with the end of #19, as Osborn crashes the Avengers' press conference announcing their new lineup. He expands on his remarks then, claiming that the Avengers are power-mad dictators who destroy anyone who gets in their way. He says the Avengers illegally deposed him from his former position of power, and he's been illegally detained without trial since then. But now HAMMER is ready to fight for the freedom of the nation.
Iron Man detects that Osborn is a hologram, and Red Hulk destroys the projector before Stark can track the source. But Osborn's words have prompted lots of awkward questions from the media.
Back at AIM HQ Madame Hydra is free from her headpiece. And she and Osborn prepare for the expected Avengers attack.
The Avengers are discussing what to do. Hawkeye points out that Osborn is right in that he was being held without trial. And he has previously proven to be a formidable adversary. Iron Man arrives from a fight between the New Avengers and Osborn's Dark Avengers with the news that Osborn is using AIM tech.
Captain America splits the team up. He details Quake to track down who planted the holographic projector. Hawkeye and Spider-Woman check out Thunderbolts Mountain. Iron Man and Protector tackle known AIM bases. Red Hulk and Storm search OsCorp Industries. Cap, Vision and SHIELD agent Maria Hill will take a quinjet to investigate Osborn's known accomplices.
Hawkeye continues to flirt with Spider-Woman. At the seemingly-deserted Thunderbolts Mountain they are attacked by Hydra agents turned into grey Hulks. But Hulks who can cling to walls like Spider-Man!
At OsCorp Red Hulk and Storm are brought down by ant-sized HAMMER agents who fly into their ears and mouths.
Iron Man and Protector are at one of MODOK's bases in Philadelphia. Iron Man is suddenly taken over and attacks Protector. There is a large explosion.
Cap has lost contact with the rest of the Avengers. The quinjet he shares with Maria Hill and Vision is attacked by a giant-sized HAMMER agent. The fact that the giant is in mid-air and looks ghost-like makes me think he's got Vision's powers as well.
