Last issue ended with Captain America, Iron Man and Thor appearing to disband the current Avengers, who were accused of collaborating with the Kree (because of their alliance with Captain Marvel).
But appearances can be deceptive. Jarvis the butler wrote to Tony Stark to resign after that, and now Iron Man has called the original Avengers together to find out what is going on. The Big Three are in Avengers Mansion when Vision bursts in and collapses. As they study his inert form, Hank Pym turns up to answer their call as Ant-Man.
They recall how Hank built the villainous robot Ultron, and Ultron created the synthezoid Vision, as they learned in #58. Ant-Man is the nearest they have to an expert on the Vision. And he and his ants now enter the android's body to find out what is wrong with him.
The first obstacle is a bunch of protective tentacles at the back of Vision's throat, which grab the invaders. They drag one ant into range of an array of spray guns round the throat, which kill it. Ant-Man uses his human strength to break free, and free the other ants. Then he sends them back out of danger.
Continuing alone he jet-packs his way through the sprays. The active defences indicate Vision's body is still working, so the problem must be in his brain. So he tries to head that way, but instead falls down a tube carrying energy pulses which are the Vision's equivalent of nerve impulses. And winds up in the chest.
While he's trying to figure out how to proceed, one of Vision's internal energy bubbles turns Ant-Man's hand temporarily intangible, as Vision can do to himself. Then Hank is attacked by small metal plates that are the equivalent of anti-bodies. To escape them he runs through bubbles to make himself untouchable. This also allows him to walk through a wall into an up-tube, and fly up to the head.
Once there he finds a loose wire. Reconnecting it starts the brain humming again. But before he leaves Ant-Man spots something strange.
Before he can investigate (or even give us a clue what he's seen) he's attacked by anti-bodies again. Diving down a hole he exits via the mouth again.
Ant-Man now leaves, saying he and Jan have still resigned, but promising to be on call if the Avengers ever need his specialist help again.
Vision awakes. Comparing notes with the original Avengers, they come to the conclusion that it was fakes who disbanded the current group last issue. Vision describes what happened afterwards.
Vision, Goliath, Quicksilver and Scarlet Witch went to a farm where Carol Danvers had taken Captain Marvel for safety. Goliath enters the property, leaving the other three to have an awkward interpersonal moment. Vision flew off, to be struck down by rays from three cows.
Lying immobile, Vision saw the cows transform into the 3 male members of the Fantastic Four, who captured the mutant twins. Vision hid underground by going intangible, then floated back to the mansion, which is where we came in.
Now we turn to Captain Marvel and Carol Danvers captives of 3 Skrulls. It becomes obvious that they were the cows/FF. The Skrulls now notice that Goliath is still at large.
Goliath comes across Rick Jones. But before Rick can tell Clint what's happening, they are attacked by the fake male FF. Goliath is knocked out, and the Skrulls tell captive Rick that they are the 3 Skrulls who were hypnotised into thinking they were cows at the end of FF#2. They have now been reactivated by their race.
Cap, Iron Man, Thor and Vision turn up at this point, and the fight resumes.
Inside the Skrull spaceship disguised as the farmhouse, Captain Marvel breaks free and frees Carol. He uses Skrull technology to turn his Kree Uni-Beam into an Omni-Wave Projector. He intends to use it to contact his homeworld. But it is also a weapon which the Skrulls would love to get their hands on.
Suddenly he destroys it. He has realised that Carol used his Kree name Mar-Vell, and deduces she is a Skrull. In fact she turns out to be the Super-Skrull, who launches the spaceship, taking Mar-Vell, Pietro and Wanda with him. He claims that these 3 were his intended prizes all along.
The other Avengers have defeated the Skrull FF. Goliath has revived, and grows enormously to latch on to the ascending craft. His punches are starting to cripple it, when his growth power wears off, and the Skrull ship escapes.
Back on the ground the remaining Avengers are dejected, especially Goliath.
