In this direct-to-video team-up feature, Tony Stark displays three armors. His initial armor, the 'Mark VI', is a slightly bulky hypervelocity armor with a circular unibeam lens. It is somewhat reminiscent of the cinematic Mark III, but with a less complex paint job and more gold color. It is first seen battling a Hulkbuster armor run by J.A.R.V.I.S. in a training exercise. This time, Stark does not wear the Hulkbuster, instead giving the torso armor and the gauntlets to Hulk for extra protection against Zzzax. Stark's final armor is the 'Mark VII', an untested prototype which has better chances of defending against Zzzax. The armor clearly resembles the cinematic Mark VI, with grey plating on the knees and arms, but with a pentagonal unibeam instead of triangular one. The Mark VII is Tony's main and only armor in the follow-up animated movie "Iron Man and Captain America: Heroes United". While there was also a Stealth armor, it was stolen and worn by Taskmaster.
