Working for Hammer
Aiding Ivan Vanko
- "Jack, try to put your head in there."
- ―Justin Hammer
However, as Hammer was examining the work that Vanko was doing, he noticed that Vanko was not creating suits of armor. Hammer asked Jack to attempt to put on one of the heads of the Hammer Drones to sarcastically show Vanko that he was not making helmets. Jack held the head and watched the two converse about making drones instead of suits of armor for the Stark Expo, before leaving with Hammer. His role following Hammer's arrest and incarceration if any within the company is unknown.
