After the fall of the UCWF, Dunphy becomes the Demolition Man and teams up with Captain America to investigate Power Broker, Inc. His costume is intentionally designed so the body of it is a duplicate of Daredevil's first costume, and the hood is a knock-off of Wolverine's. He successfully rescues Captain America from Karl Malus and helps Captain America catch him. Dunphy is captured by the Power Broker and is subjected to further treatments which augment his strength further but damage his heart. While under the influence of the stimulant, he goes mad and attacks Captain America. Dunphy suffers a heart attack, his second augmentation is reversed and he is hospitalized. Dunphy then takes a step back from superhero activity to take over Captain America's hotline.
