Set during The Initiative storyline, the new team is introduced with Iron Man, The Wasp, Black Widow, Ms. Marvel, Wonder Man, The Sentry, and Ares. The team is assembled to fight the Mole Man's creatures, while a series of natural disasters are reported around the world. In the heat of battle, Iron Man's systems are overloaded, morphing him into a beautiful woman who resembles Janet Van Dyne, The Wasp. It is she who figures out that this is the new and improved Ultron.

The Avengers battle Ultron, while Henry Pym is summoned by The Black Widow, who has taken over the direction of S.H.I.E.L.D. Ultron distracts The Avengers with multiple versions of Iron Man's armor, while she disappears from the battlefield to attack The Sentry's wife. When the Sentry discovers what Ultron has done, he battles her while Ares develops a plan to defeat Ultron with Ant-Man's help.

Mighty/Fantastic (Issues #25-26)

In escaping H.A.M.M.E.R. agents, Jocasta inadvertently untethered the Mighty Avengers' "PymPocket" base from reality, causing its dimensional doorways to slowly fade. Henry Pym contacts Reed Richards, hoping to borrow a device that had been left in the Fantastic Four's care by Bill Foster. Reed refuses, and Pym decides to have his team break in the Baxter Building and steal the device. Despite Reed's best attempts, Pym is successful, and manages to move the Pym Pocket to a new dimensional location. However, the degradation of the dimensional gateways requires Jocasta to be integrated into the system in order to hold it together.

The Unspoken (Issues #27-31)

 * Writer: Dan Slott Artist: Khoi Pham

While the rest of the team settles into their new base, "The Infinite Avengers Mansion", U.S. Agent and Quicksilver encounter The Unspoken in China. Quicksilver explains that The Unspoken was the Inhumans' former king, before he was deposed and banished by his cousin Black Bolt for his power-hungry ways. Before the two can act, The People's Defense Force (China's Superteam) accost The Unspoken, demanding he leave the country. The Unspoken responds by defeating them in an instant, prompting U.S. Agent to suggest calling not just their team, but all the Avengers teams to combat such a threat.

Meanwhile, Stature desires revenge against the Scarlet Witch for the death of her father and has lured the Young Avengers to assist her. Ronin (Clint Barton) follows them, also desiring revenge against "Wanda". During the fight, Wiccan uses his powers to break through Loki's illusion, but the villain retreats before he is fully revealed.

While Hercules and Amadeus call the other Avengers teams for help, USAgent, Quicksilver and the recovered Chinese heroes attack The Unspoken, who uses Xerogen Crystal powder to turn them into Alpha Primitives. The other Avengers (barring Osborn's groups) join the battle, but many of them also succumb to the powder's effects.

At the same time, Pym is exploring the outer reaches of existence. There, he encounters Eternity, who thanks him for saving his being from succumbing to the chaos wave, and tells him that he is the universe's Scientist Supreme. Upon his return to the universe, Pym marshalls the remaining Avengers, having Amadeus and Hercules infiltrate the "Slave Engine", which contains a supply of Xerogen Crystals, and disable it. Pym then uses the engine's chronal ray, used to accelerate the growth of the crystals, on The Unspoken, turning him into a weak old man.

Mighty/Dark (Issues #32-33)

 * Writer: Dan Slott Artist: Khoi Pham

Loki engineers the escape of Crusher Creel, manipulating him into raiding Project Pegasus, bringing Norman Osborn's Dark Avengers to the scene. He also takes on Scarlet Witch's appearance once more in order to bring the Mighty Avengers to the same place. As Osborn's group is in the middle of a press conference, he can not afford to fight Pym's publicly popular team, and grudgingly joins forces with them. Creel then appears, having absorbed the power of a Cosmic Cube fragment. As their two teams attempt to stop Creel, Pym and Osborn both realise that Creel's wrecking ball, which shares his powers, has also turned into a Cosmic Cube, and race to retrieve it. Osborn is first, but Pym tricks him into believing that he had already gotten it, claiming that the Dark Reign was made possible by the Cube's power. Pym then knocks Osborn out, and uses the Cube as a weapon against Creel, with limited results. Loki then appears, and provides Osborn with a mystical blade, which has the ability to remove Creel's Asgardian-born powers. Using the weapon, Osborn defeats Creel, making himself look like a hero in the eyes of the watching media. Osborn uses his status as head of H.A.M.M.E.R to decommission USAgent, removing him from the Mighty Avengers. Pym's Avengers return to the Infinite Mansion, where Pym consoles himself with the fact that he recorded Loki's image, and now has a scan of his retina.
