 Later, Justine Hammer became a recurring adversary to Tony Stark in "Iron Man", beginning with the 2010 storyline "Stark Resilient", which is part of the overarching storyline "Heroic Age".Justine has since ostensibly left supervillainy to take the reins of Hammer Industries, along with her daughter Sasha Hammer, and begin promoting their own line of mechanized battlesuits to sell to both the military and private interests, Detroit Steel.While the initial presentation is considered a bust, as the investors have little interest with Tony Stark's return, Stark then announces that he is leaving the weapons industry, and his interest in using repulsor technology to give free energy to the world, making the military interested again in Detroit Steel.
