Synopsis
Captain America, Giant-Man, Iron Man and Thor have gone into a microworld to rescue the Wasp. The rest of the main Avengers team (Hawkeye, Red Hulk, Spider-Man, Spider-Woman, Vision and Wolverine) were left behind to guard the portal Henry Pym set up. Then Avenger/SHIELD Agent Quake turned up, and called in SHIELD.
Now a SHIELD squad has arrived to cordon off the area, led by Maria Hill, sometime Avengers liaison. But also a load more Avengers are here (New Avengers:- Daredevil, Dr Strange, Iron Fist, Mockingbird and Thing, Secret Avengers:- Beast, Black Widow, Sharon Carter and Valkyrie, and the at this point unaffiliated Scarlet Witch and Carol Danvers in her new role as Captain Marvel)
There is a priority spat between Director Johnson and Commander Hill, which ends when Hill tells Black Widow and Hawkeye to go get some Pym particles from Hank's lab so they can send backup into the microworld. But Wonder Man has beaten them to it. And now, desperate to prove himself worthy to become an Avenger again, he uses the particles and the portal in an unauthorised shrink.
In the microverse Cap and normal-sized Giant-Man and Wasp are floating in individual force-bubble prisons amidst a fleet of exploding skycraft. Suddenly their bubbles pop. Free to grow enormously, Hank grabs the other 2 and plants his feet on the ground.
It is Thor who is causing the havoc. Until he sees Iron Man falling, powerless after expending his remaining energy blasting the centaur-like crimelord Gouzar. Said Gouzar is following him, now with metal airplane-type wings. Gouzar attacks Thor with his built-in cannon. Until Giant-Man hurls Cap at him as a fighting distraction.
Thor saves the falling Iron Man, and Giant-Man catches them both. As Wasp herds alien bystanders away from the falling flagship. Iron Man is still trying to get his armour up and running, and Thor is weakened in this alien environment. Lord Gouzar is throttling Cap. When suddenly Wonder Man arrives to take over the fight.
Now it's Thor's turn to catch a falling Cap, as Gouzar's alien horde converge on Wonder Man. Cap, Hank and Thor rejoin the fight. Wasp continues helping civilians. But Iron Man is still out of it. Until some enemy troops attack *him*, and he can use the power of their blasts to recharge his armour.
He seems to go straight from empty to full, and then to overflowing. A surge of energy brings down all of Gouzar's remaining attack craft. Gouzar is about to shoot Stark in revenge, and in the back, when Wasp flies up and blasts him out of the sky, shattering his helmet.
Jan stands over the fallen villain, and tells the inhabitants of the city that they are now free.
This all couldn't have taken very long, or time runs differently in the microworld, because back on Earth Maria Hill is just telling Black Widow and Hawkeye to continue with the plan to get Pym particles. When the 5 Avengers burst out of the portal. Wasp is glad to be home, and everyone is overjoyed to see *her*. But the joy doesn't last long, because Lord Gouzar follows them.
What follows is several full-page panels of the assembled Avengers beating on Gouzar. Each page done by a different guest art team.
Then Hank Pym sends the unconscious villain back home.
In an epilogue everyone gathers in Avengers Tower for a welcome home Wasp party. Wonder Man is back in their good books (after being a thorn in their side for the last few years). All the participants are there, plus Black Panther, Luke Cage, Jessica Jones and Moon Knight. All served of course by the ever-faithful Jarvis.
Cap and Iron Man ponder what now for the Avengers. Steve thinks Wonder Man was at least partly right - the Avengers *do* seem to cause as many problems as they solve. But Tony brushes that aside, and suggests the solution is to make the team even *bigger* than it is now. Cue the Marvel NOW series.
