13 Intriguing Potential Fates For Iron Man In The MCU

13. He Simply Retires Completely

If Robert Downey, Jr. gets too old to continue playing Iron Man and the Marvel Cinematic Universe continues to flourish with a plethora of new characters (the likes of Black Panther, Doctor Strange, Daredevil, Ms. Marvel and many more are on their way), then his character could bow out with dignity by simply retiring once he's fulfilled his heroic duty and passed on his wisdom to the up-and-comers. It wouldn't be spectacular, but it would be a neat and tidy way to end his tenure and knowing that Tony Stark was able to enjoy his life, having given so much to the world by fighting the heroic fight as his armoured alter-ego, would be pleasing to his fans - assuming he has a bit more to give from this point onwards, anyway.
