If there was one absolutely good thing to come out of Civil War, it was the Initiative. The comic was awesome the whole run and the team(s) really meshed well into all the crazy Marvel events that kept popping up.
Gauntlet was the head trainer of the Initiative, and he basically had a big alien robot hand that wouldn't come off. It could also project some sort of energy fist. He was a real BAMF during the Initiative though, and then went on to head the Avengers Resistance against Norman Osborn and Hammer. I think afterwards he went back to the Army to help out in warzones.
