War Machine (Earth Infinite)

Origins
When seeing Tony Stark (who is also secretly Iron Man) struggling against the wreaking crew, he decided to give Tony a hand by accessing a new armor that he was designing for Tony Stark. The addition to Iron Man's side was helpful to his side but before Tony had the chance to say thanks, War Machine took off, unbeknownst to both Tony and Rhody that they were partners when the Wrecking Crew appeared.

When the avengers where having problems with Ultimate Ultron the Black and Silver iron boss came back and help the Avengers and fought alongside with Earth's Mightiest Heroes.

Before War Machine taking off, Iron Man thanks him for saving him from The Wrecking Crew and helping him against Ultron, Iron Man curious to see who this War Machine is he shot a tracking monitor on War Machine, following for hours he eventually unassembeled the War Mahine Suit and found out it was Rhody.
