Synopsis
This issue runs in parallel with Dark Avengers #15 with many shared scenes with different contents. There are also connections to the Siege: Loki 1-shot and Avengers: Initiative #31.
It opens with Norman Osborn sitting on his bed as his Green Goblin mask gives him advice about Asgard. (Siege: Loki will let us know it's really invisible Loki doing the talking.) Asgard the city is currently hovering a few feet above the ground outside Broxton, Oklahoma and the mask says it's obviously there flouting his authority. He must assert that authority and do something to get rid of it. Norman wants to consult Loki but the mask tells him not to trust the Trickster God. Osborn is persuaded.
The next scene is in Avengers Tower. Bullseye and Moonstone are asleep in their (separate after being reprimanded in DAv#14) beds. Osborn is in his Iron Patriot armour (sans helmet) in a meeting room with Loki, Hood and Taskmaster waiting for the only other remaining member of the Cabal to join them. Doctor Doom seems to arrive via Cosmic Cube, but it might be some other technology or magic.
As usual Doom impatiently asks what Osborn wants *this* time. And who is the extra member - Osborn introduces Taskmaster (inducted in Av:I#31 to swell the dwindling ranks). Doom immediately takes over the agenda and tells Osborn to stop making moves against his ally Sub-Mariner. (This would be the attack on the X-Men and especially Namor in Dark Reign: The List: X-Men.) Norman responds that Namor and Emma Frost need to be punished for betraying him and the Cabal (in the Utopia crossover). Doom accuses Osborn of turning on any 1 of them who displeases him. Norman counters that he helped Doom regain Latveria as promised (DAv#1-4) and now he wants to help Loki take over Asgard and take it away from Earth. Doom says he'll help but he wants Osborn to 'produce' Namor 1st. (But Osborn doesn't *have* Namor - he and the Atlanteans are living under the X-Men's new home on the artificial island Utopia.)
At this point Norman decides it's time to take back the initiative and bring Doom into line. He summons his secret weapon (which DAv#15 reveals is Sentry's dark half the Void in his nonhuman energy form) who blasts Doom against a wall. Iron Patriot dons his helmet as things heat up. Loki advises *his* ally (as seen in issues of New Avengers) Hood to leave, which he does by magic. Doom blasts back but hits Taskmaster (which puts him in hospital as seen in Av:I#31, which also has a Taskmaster's-eye view of this meeting). Void blasts Doom again and the armoured form falls.
But it's not Dr Doom it's a robot which emits a horde of flying robot bugs which invade the whole Tower. (Loki is unaffected, probably intangible.) Osborn contacts Victoria Hand and orders a complete evacuation. We see her telling the Dark Avengers present (Bullseye, Daken, Moonstone and Venom) to go to the quinjet on the roof despite Venom wanting to stand and fight.
Iron Patriot's armour AI can't find a way to combat Doom's (probably partly magic-based) attack. (At this point DAv#15 shows us Osborn ordering Void to switch to Sentry (and to Bob Reynolds who I believe doesn't know the Void interludes happen).) We then see Sentry bringing his wife Lindy Reynolds to join the others on the roof, and asking what's going on. He drops Lindy off at the quinjet and flies off to see if Norman is alright. IP is still trying to shut off the power to the bugs when Sentry arrives, rips the collapsed Doom robot in half and smashes the halves together. There's an explosion and all the bugs fall to the floor.
Patriot picks up 1 of the bugs which opens a communication channel to the real Dr Doom. They exchange threats and the bug self-destructs.
The final scene has Osborn talking to a hologram of the President who refuses permission for him to invade Asgard. When the conference is over Norman turns to Loki who has a plan. He reminds Norman how Civil War I was started (via the Superhuman Registration Act) by the Stamford incident. He says he can arrange such an incident to make the public demand a war on Asgard.
