Tony Stark (and Robert Downey Jr., who portrays him) is the heart of the Marvel Cinematic Universe, and the tech billionaire has made smaller and smaller appearances in the universe since Age of Ultron.
Before trying to determine where Iron Man is prior to Avengers: Infinity War, it's prudent to go back to the beginning to see where Stark's been and how he's become the man he is. The MCU is a rich saga, and it all began with Iron Man in 2008. From those humble beginnings it has grown into a tale of cosmic proportions, with one of the biggest bads of all knocking on the door of the Avengers as the impossibly strong Thanos (Josh Brolin) finally invades Earth.
Through all of this, Stark has evolved drastically as as person, yet he still possesses fundamental flaws that have profound effects on the world. Fans have been speculating as to who might die in Infinity War, and Stark's massive ego could cost him his life. Stark fans can only hope he gets it together so he can be a part of the MCU's Phase Four.
