What If? (2004) #1

Meet again, for the first time, General Thaddeus "Thunderbolt" Ross... a veteran army officer who believes that the time for talk is long past, and all that matters is his country's ability to develop weapons that will annihilate its enemies. Experience with him what happens when he himself becomes the mightiest weapon on two legs...but is trapped within that weapon, unable to communicate with former allies who only want to destroy him.
