After nuclear war and biological attacks from the Black Scythe wiped out much of humanity and devastated the world, Stack lived with the descendants of the employees of the White House who survived the onslaught in a hidden bunker beneath the structure. The community didn't have leadership; instead, Stack acted as the community's adjudicator.
One day, he and the survivors stumbled upon the Hulk after he followed one of the survivors into a passage that led into the bunker. Stack greeted Hulk but told him that his large size meant that he would greatly lessen the time their supplies lasted. Stack then showed Hulk a city called Dystopia, which was built upon the ruins of New York City by someone called Maestro. Curious about Dystopia, Hulk left the bunker and ventured toward the city.
Years later, Hulk became the new Maestro of Dystopia and began conquering neighboring territories. When Stack and his community became the Maestro's next target, Stack evacuated everyone out of the bunker and distracted Maestro with a duplicate of himself while he and the community got away in a plane. The duplicate then detonated a bomb, destroying the bunker and leaving Maestro humiliated.
