After the Mark VI sustains damage during the attack on the S.H.I.E.L.D. Helicarrier, Tony Stark uses the Mark VII armor to help repel the Chitauri invasion of Manhattan. The Mark VII is assembled onto Stark's body via wristbands that emit a signal to summon the armor, which is launched as a bulky capsule, and then places itself onto the wearer of the wristband, in a manner similar to the Mark V, after scanning his or her body. The Mark VII was not designed for deep space travel, as the armor's systems failed, causing Stark to lose consciousness as he plummeted back to Earth. Phil Saunders stated that "[Avengers director] Joss Whedon was looking for something that had the 'cool' factor of the suitcase suit [from Iron Man 2], while still being a fully armored, heavy duty suit that could take on an army in the final battle." To that end, Saunders borrowed ideas that had been proposed in Iron Man 2 as well as some ideas that had been abandoned in Iron Man and merged them together in a modular suit that has big ammo packets on the arms and a backpack.
