10 MCU Moments More Important Than You Realised
5. Tony Saves Yinsen's Townspeople (Iron Man)
Considering Tony's ultimate sacrifice in Avengers: Endgame, Yinsen - the man who implored the self-absorbed billionaire to not waste his life, setting him on a more heroic path - is one of the most important characters in the MCU.
Tony doesn't waste any time in heading down that heroic path either, strapping on his new-and-improved Iron Man suit midway through the original movie, and using it to free the citizens of a small town from the Ten Rings' callous grip.
It's a badass action sequence and a real turning point for Tony, but the scene also has a much deeper meaning that isn't readily apparent on the surface.
The town that Tony liberates is actually the same town that Yinsen is from, a connection that isn't obvious unless you're paying close attention when Yinsen mentions its name - Gulmira - during a cave scene early in the movie, and again when Tony hears it while watching a news report.
This means that Tony isn't just helping these townspeople because the Ten Rings are stationed there with Stark weaponry - he's helping them so he can honour the fallen friend who saved (and changed) his life.
