Synopsis
Last issue Norman Osborn sent the Thunderbolts to sneak in to Asgard, during the invasion by his Dark Avengers and HAMMER and others, to steal the Spear Of Odin. They located it but were then intercepted in the Asgardian armoury by some ex-Mighty Avengers (Amadeus Cho, Stature, U.S. Agent and Vision) (who had been alerted by the TBolts' missing member Ghost).
US Agent attacks Grizzly. Giant Stature stomps on Scourge (Nuke) while Ant-Man ducks out of the way. But Grizzly throws USA at Stature, knocking her over. Amadeus tells them to take out Scourge, who's really Nuke, and Mr X 1st because they're the deadliest. Mr X comes after him. But Cho grabs a quiver of large Asgardian arrows and tips them out in such a way that they ricochet and fall towards X - so many of them that he can't avoid being pierced by *some*. And all this calculated by Cho's amazing brain. Scourge grabs little Ant-Man and tells him to stop hiding and orders him to grow giant-size and take on Stature. He hurls the mini-man who expands in flight and knocks Cassie Lang down (again).
Meanwhile Paladin has sneaked over to where they found the Spear. Vision accosts him and asks the honourable mercenary why he's working for Osborn. Paladin throws the Spear at the synthezoid, which passes through his intangible body but disrupts his system in passing. It then exits the building leaving destruction in its wake. The glitching Vision can still tell where it lands, causing more destruction. USA says they've got to keep it out of Osborn's hands, but Scourge disagrees and drop kicks him and Cho. Grizzly tips Stature out of the tower, and her falling big body causes yet more destruction. But she gets back up and throws a giant statue at him.
Eric O'Grady has shrunk down to man-size and detects that the Spear is still on the move. Paladin tells him they've got to get it before Scourge or Mr X do - Ant-Man is confused but agrees. Scourge is more concerned at the moment with shooting at Stature until USA shoots the gun out of his hands. Those 2 fight, during which Agent knocks Scourge's facemask off. USA is surprised to see a face tattooed with the Stars And Stripes (maybe he wasn't listening when Cho told them Scourge was really Nuke, so Nuke repeats the info now). This tests the limit of John Walker/Jack Daniels' political support for Norman Osborn, so he beats Nuke up and tosses him into a blazing fire.
Vision is increasingly suffering from the effects of the Spear. Amadeus tries to help but then Ghost materialises by them. Mr X finishes ripping arrows out of his body and then goes after the Spear just in time to see Ant-Man (still man-size) dive for it, and Stature grab him before he can grab *it*. But Eric astonishes Cassie by telling her she can have it as long as she keeps it out of Osborn's hands. However it's Paladin who gets his hands on it (again), but US Agent takes it off him. It's Paladin's turn to echo Ant-Man's sentiment and urge USA to take the thing far away.
But no-one gets to take the Spear anywhere because it's at this point that Sentry blasts his way through Asgard and the hovering city starts to crumble and fall to the ground (see the end of Siege #3). As everyone tries to survive the devastation a burned but determined Nuke reaches the Spear, seen only by the Agent. So he uses it to slice John/Jack's left arm and leg off, and claims the Spear for HAMMER and Osborn - mission accomplished.
