The Iron Giant Man is the robot built in the memory of the Giant Man along with the rest of the Iron Avengers. Like the others, it was built by Iron Man to battle Ultron but was never used. It contained the Iron Wasp swarm. When James Rogers activated the Iron Captain America, Iron Cap activated the rest of the Iron Avengers. It flew off with the rest but was corrupted by Ultron. They attacked the Scavengers at the Ultra City Citadel. It eventually came to the desert and fought Henry Pym, Jr. and released the Iron Wasp swarm. They attacked Bruce Banner who became the Hulk who then destroyed them and Iron Giant Man.
