Years after Tony Stark’s death, the world has moved on—but his technology hasn’t. When a covert group hacks into one of Stark’s forgotten AI defense programs—Project: Legacy Protocol—an army of autonomous drones built to protect humanity is accidentally unleashed across the globe. Without Stark to control them, they follow their last directive: eliminate all threats—and that now includes humanity itself. To stop them, Riri Williams (Ironheart), a brilliant young engineer mentored indirectly by Stark’s archived AI messages, takes up the mantle of innovation. But she’s not alone. James “Rhodey” Rhodes (War Machine) returns to help guide her while battling his own doubts about carrying on Tony’s legacy. Meanwhile, a mysterious tech broker known as The Ghostmaker—who claims to be a rival of Stark from his early years—seeks to twist the Legacy Protocol for his own ends, wanting to rebuild the world under his vision of “perfect order.” As Riri uncovers hidden messages Tony left behind, she begins to realize that Iron Man didn’t die with Stark—he left a roadmap for the future. Together with Rhodey and a rogue Stark A.I., she must battle both physical and philosophical threats to become something new: not just Ironheart, but the evolution of Iron Man.
