Decades in the future, Iron Man disappeared for a month, and the Avengers and Pepper Potts wondered what happened to him. A month later, they found a monolith built by Stark in the desert, but no one could penetrate it, not the Avengers and not the villains (three seen, none identified). Decades later, Pepper Potts, dying at age 94, made her granddaughter promise to find Tony and make him come outside. She broke into the monolith and convinced him to see that his inventions had changed the world. As he lay on his deathbed, he had another idea.[1]
