Synopsis
This issue starts soon after the bit in Avengers & X-Men: Axis #4 where Iron Man downloaded Extremis 3.0 to everyone in San Francisco, giving them the option of using it to perfect themselves. Now he basks in their adulation.
Then it jumps to 1 week later when the Axis Event is over. The previously page, title page and a text page at the back explain what has happened. The inversion in Axis #3 reverted Tony Stark's personality to the self-centred egotist he was before the event that made him Iron Man. Spoiler alert - at the end of Axis most character inversions get reversed, but Stark deliberately avoids it.
Now Iron Man helps She-Hulk deal with a wannabe supervillain calling himself Teen Abomination - a cut-down version of Hulk's old (and dead) foe who is still able to punch out Shulkie and literally knock Shellhead's head off. Of course this IM is just a remote-controlled drone, which uses its own head to beat Teen-A to a pulp. Tony Stark then leaves Jennifer Walters to handle clean-up, and brings his attention back to where he's floating in a pool full of perfect people. And he's back to drinking alcohol.
His idyll is interrupted by Pepper Potts (presumably still CEO of his company) who's flown all the way from New York to nag him. He shows her a part of his new silvery Endo-Sym armour - a liquid smart-metal based on a (Venom?) symbiote. But she really wants to question his idea of giving everyone Extremis - or at least those who have access to it.
To exemplify her misgivings we see a group of the new beautiful people harassing a non-beautiful homeless person for spoiling the view. But we also see San Francisco's other new super-resident Daredevil intervening. However before he can do much something else happens.
Tony's liquid armour has by now completely engulfed him except for his face, as he explains to Pepper that Extremis is going to make him a lot of money. Outside at the pool the perfect specimens of humanity have now reverted to their ordinary selves. And their phones advise them that the Extremis treatment can now be theirs again for $100 a day.
Later Pepper reviews the situation with a silhouetted figure who could be Daredevil or Black Panther. She figures Tony's mind has been 'taken', so they need to activate the contingency plan. And her companion turns out to be an old Iron Man armour.
