James Rhodes Iron Man/War Machine

When Tony Stark was battling his alcoholism his friend James Rhodes took over as Iron Man. While he did a good job he started to get headaches and have attacks of erratic and violent behavior. It was reveled that the reason was because the armor was tuned for Tony Stark’s brainwaves only. Tony was still recovering and not able to wear the armor but he did what he could to help Jim maintain his sanity. However, he grew more paranoid and Tony had to put on prototype armor to stop him. Tony eventually took over the armor again and designed a suit of armor for Jim Rhodes that he wore and called himself War Machine. He fought side by side with Iron Man till Tony Stark had to fake his own death. When Jim Rhodes found out he was alive it ended their friendship and Iron Man and War Machine went their separate ways.
During a solo adventure War Machine got some alien armor. When it seemed that Stark had died for real Jim Rhodes went back to Stark Enterprises. He used his armor to erase any trace of the Iron Man armor from the computers memory to keep it out of enemy hands. After this Jim Rhodes gave up his superhero career.
Later, when it turned out Tony Stark had not died, Jim and Tony became friends again and fought together against a villain who was calling himself War Machine. Currently Jim Rhodes is head of Sentinel Squad O*N*E. He wears armor that they made from Sentinel technology.
