Sometime after the Extremis transformation, during at attack by the new Super-Adaptoid, Tony Stark realized he could command several armors at once. Building on this, and realizing the world was becoming an increasingly dangerous place, he decided to construct a "team" of Iron Men - hyper-advanced drones that would be under his direct mental command, just as his own armored body. Unfortunately, the "Argonauts" were abused and destroyed before they ever could serve for good. They included:
-"Space Ghost"; space-flight capable, nearly-impossible to detect espionage model; possibly intended as a satellite-killer.
-"Submariner"; streamlined for great speed underwater; capable of using the ocean itself as a weapon, it apparently unleashed several tsunamis.
-"Adamantium Man"; equipped with practically indestructible "Stark-Chobham" armor.
-"Digger"; enormous droid, possibly over a hundred tons; equipped with (shielded) Antarctic Vibranium (which dissolves any metal) helmet dome and a specialized repulsor/unibeam system which allowed it to tunnel at incredible speed.
-"Hulkbuster"; also massive droid, ostensibly designed mainly for raw power and toughness, to take on the Hulk.
While extremely powerful, the drones were useless once Tony Stark was eliminated.
Types of Drones:
Battle Argonaut
Hulkbuster Argonaut
