Later, Curtis came to work at a division of Stark Enterprises as a research scientist and Director of Research and Development at Stark Prosthetics in Denver, Colorado. He created an artificial prosthesis to replace his missing foot. Stark Prosthetics ended up attacked by the Wrecker during the "Acts of Vengeance" when the Kingpin sent him to attack Iron Man. Curtis aided Iron Man and Jim Rhodes against the Wrecker and Calvin, although Calvin destroyed Curtis' left foot. After that attack, Curtis made another prostheses for his other foot.
