The Igor Armor was made by Tony Stark shortly after the Battle of New York. As part of the Iron Legion, the Igor armor was used during the Battle on the Norco, against Aldrich Killian and his Extremis soldiers. When the destruction of Piston caused structural instability to a platform among the docks, Stark summoned Igor to stabilize and support the platform. Igor was later destroyed when Stark activated the Clean Slate Protocol. 
The Igor Armor is much more powerful in terms of brute strength than any of the other Iron Legion Armors, as well as being extremely durable, making it a formidable opponent in battle. However, it was designed specifically for heavy lifting, not combat. The Igor armor contains a variety of mechanisms in its legs and back that can lock into place, allowing it to support structures that have quadruple the mass of the suit on its back for an extended period of time without failing.
- This armor resembles the Hulkbuster armor from the comics, and as its concept art had the traditional red and yellow color scheme, it was assumed to be it until Iron Man 3 was released and confirmed it was another armor.
- The Clean Slate Protocol was designed to self-destruct all remaining armor suits after the battle; however, as the platform Igor was holding was shrouded by smoke and dust at the end of the battle, it was unsure if Igor was destroyed in combat or destroyed by the Protocol.
- The armor's name "Igor" is a reference to Dr. Frankenstein's assistant Igor, who possesses a similar hunchback.
