Synopsis
Last issue Stature gathered together an assembly of Avengers (from the New Avengers, the Young Avengers and the Avengers Resistance as well the Mighty Avengers) to go to Tibet to help fight the Unspoken, who has unearthed the flying Slave Engine which turns Exogen Crystals into a mist which turns humans into Alpha Primitives - the slave race of the Inhumans. (He is an ex-king of the Inhumans who was banished for hiding the Engine away from his people so they couldn't use it on humanity. Since then he's changed his mind and now wants to get back into the good graces of his people.)
Quicksilver and U.S. Agent were already on site with Ban-Luck of GRAMPA, the People's Defence Force and some Chinese troops. But the troops, US Agent plus Collective Man and Lady of Ten Suns of the PDF have already been converted to Alpha Primitives and turned against their comrades Ban-Luck and Quicksilver plus Radioactive Man and Scientific Beast. However when help arrived Justice and Spider-Woman immediately succumbed to the gas, and now Tigra and Wiccan get it too.
Unspoken continues to speak the usual villain rant explaining what he's doing and why. He now says that it was the Silent War (when humans attacked Inhumans, as he puts it) that made him turn against humanity. And Pietro Maximoff realises that makes it *his* fault - it was Quicksilver stealing Terrigen Crystals that initiated the hostilities.
In the Infinite Avengers Mansion Wasp (Henry Pym) returned at the end of last issue from Overspace and his chat with Eternity. Now he tells Edwin Jarvis and Jocasta to tend to the injuries of Young Avengers Hawkeye and Speed (from #28-29 fighting Loki pretending to be Scarlet Witch). He can't wait for Reed Richards to return their call (last issue) so he takes the guns he grabbed and charges out of 1 of the Mansion's many doors to Tibet. Ronin is glad to see him and asks what his plan is. Hank says give him a minute to make 1 up (despite Eternity seemingly giving him 1 last issue).
Wasp contacts Amadeus Cho's Ant-Man helmet. He and Hercules are on board the Slave Engine fighting (well, Herc is) a large robot. Henry sends Cho to turn off the gas. Amadeus runs into 3 human-sized robots. He quickly calculates the angles and throws a coin which hits them all in strategically disabling spots. Then he reaches the heart of the ship where a mountain of Exogen Crystals is being automatically fed into a huge furnace, creating the gas which being continuously pumped out.
Wasp tries a different tack. He grows to giant-size, activates his Toolbot into a laser sword and intends to knock the Engine out of the sky. But Unspoken uses his ability to change his Inhuman power so he too can become a giant, with a laser-fist. They begin to duel.
Down below the just-very-big Stature is fighting foes on the ground with Captain America (Bucky Barnes), Gauntlet, Radioactive Man and Rage. Ronin tells fliers Hulkling, Ms. Marvel, Scientific Beast and Vision to go help Hank destroy the ship. And he tells Cassie Lang to get even bigger to keep out of the low-lying gas. But she's exhausted so he suggests another trick. She shrinks and rides the tip of an arrow he fires . Cap throws his shield to force open a crack in the ship's armour-plating for the arrow to pass through.
Then the gas gets everyone left on the ground (including a so far unmentioned Patriot) except Quicksilver (who whirls it away with his speed) and Radioactive Man (who continues to transmute the gas around him with his radioactivity).
Henry Pym is losing the giant-size duel but takes time to tell Unspoken to stop dwelling on the mistake he made in the past and look to the future. Amadeus Cho overhears this through his comm-link with Wasp and it gives him a plan. He realises that the supply of Exogen Crystals is being continually increased by a chronal ray which is rapidly growing them from little ones. He calls for Vision to come help.
The 4 fliers are fighting 3 Alpha'd flying opponents Justice, Lady of Ten Suns and Spider-Woman. Jonas leaves the other 3 and phases into the ship where he finds his girlfriend Cassie. They run to keep Alphas and robots off Cho (Stature has got her 2nd wind and is big again).
On the ground US Agent has grabbed Quicksilver, but Pietro gets through to him by claiming that he's letting the Commies win. The ultra-patriot turns on the Alpha Primitives and leaves Quickie alone. The speedster then throws a rock hitting the giant Unspoken in the eye. Hercules has gained control of the Slave Engine and turns it so Cho can fire the chronal ray at the Unspoken, rapidly aging him.
Afterwards they use the chronal ray to reverse the lives of those converted to Alpha Primitives so that they become human again without memory of what happened. To avoid legal hassles with the Inhumans the Chinese agree to let the now harmless Unspoken return to his cave with his real Alpha Primitive servants. Clint Barton suggests Hank could use the ray to wipe his own mistakes from his memory, but Pym declines because he's moved on. Ronin also tells Wasp that the 'Scarlet Witch' the MAv has been working with wasn't the real deal. (Pym says he'd already worked that out and had been building up to a confrontation.)
Finally Quicksilver uses a Mansion door to take him to the Inhumans in Attilan on Hala in the Kree Empire that they now rule. He returns the Exogen Crystals to them. But he also repeats the lie he'd used in #24 that all his bad actions since House of M were actually due to a Skrull who'd replaced him leading up to Secret Invasion. Medusa accepts the explanation and they're all friends again. Except that his daughter Luna's power enables her to see the truth. She tells him she'll keep his secret but he's lost her respect.
