The character has made minor appearances across several media, such as animated television and the live-action Marvel Cinematic Universe film Iron Man 3 in which he was portrayed by Ashley Hamilton.

Jack Taggert worked on an experimental pilotable suit for Project: Firepower for Edwin Cord (a rival businessman of Tony Stark).

The project was ostensibly designated by the U.S. Armed Forces, in conjunction with Senator Boynton, to serve as an ultimate deterrent against opponents of the United States.

The tests against tank and jet drones proved so devastating, however, that Rhodey suggested aborting; however, determined to destroy every last bit of Iron Man technology not under his control, Stark joined the fight.

Taggert launched the "Terminax", a low-power nuclear missile, and completely destroyed the Iron Man armor, leaving its bloody bits to fall to the desert floor.

[1] Stark had faked Iron Man's death by sending out the "Silver Centurion" armor on autopilot, filled with the store of spare blood they had kept on board the chopper "just in case", so as to allow the world to believe that Iron Man was dead (Stark's injuries were blamed on the shockwave from the Terminax detonation).

Finally having had enough of Firepower, Stark locked himself inside his private laboratory to build a brand new set of armor, incorporating several improvements and new weapons, as well as the "classic" red-and-gold color scheme.

However, the launcher backpack that housed the missile had been damaged by Iron Man's pulse bolts, trapping the Terminax and threatening everybody in the vicinity.

Iron Man used an electromagnetic pulse - a trick learned from Force - to disable the Firepower armor (and his own) for six minutes.
