As we all know that Iron Man star Robert Downey Jr is one of the most loved stars around the world. Not only is this he one of the most important reasons that Marvel Cinematic Universe has turned into this big box office overwhelming from last ten years. He was the one who started it all with Iron Man back in 2008 but back in 2012, after the release of Marvel's The Avengers, reports were rift that his contract is ending after Iron Man 3 but, due to his matchless popularity and high demand among pop cutler nerds, his contract was further extended and he was further featured in Avengers: Age of Ultron, Captain America: Civil War, a cameo in Spider-Man: Homecoming and this year's Avengers: Infinity War.
Before the release of Avengers: Infinity War it was extensively reported that the film will be the end of Iron Man aka Tony Stark and also see depart of Robert Downey Jr from the MCU. But, that did take place...almost anyway, touted to be the end of the ten years of the Marvel Cinematic Universe, Avengers: Endgame is likely to see the closing stages of the original Avengers.
