James Stewart (Earth-5171)

Colonel James Stewart is a U.S. military officer and jet pilot from Detroit, Michigan. He is the best friend of Tony Stark and the liaison between Stark Industries and the military in the Department of Acquisitions. He began to be known as War Machine when wearing his heavily-armed battlesuit from Stark Industries that he began to use after Tony Stark was seriously injured in a disaster. For some time, Stewart occasionally filled in for him, including on some missions with the Avengers. He then began to act as a hero on his own, often helping out Iron Man and the Avengers.
