He may not be the most powerful hero, but Iron Man is clearly the heart of the Marvel Cinematic Universe. His first solo film in 2007 kick-started the shared universe and directly led to the Avengers joining forces on the big screen. After starring in three solo movies and playing prominent roles in three other Marvel films, now seems like an appropriate time for Iron Man, or at least for Tony Stark, to slowly bow out of the spotlight.
Ever since The Avengers, Stark has been obsessed with the bigger threat out in the Universe. Well, Thanos finally launched his primary attack in Avengers: Infinity War and Iron Man is going to have to think creatively to save the universe. Rumors have been pointing for years that Robert Downey Jr. is ready to say goodbye to the Marvel Universe, but if that happens, Marvel will have to send Iron Man out in style. Whether he sacrifices himself to resurrect the universe or just stalls Thanos long enough for Doctor Strange to save the day, the potential loss of Tony Stark will leave a giant, Iron Man-sized hole in the MCU that will desperately need filling.
