The MCU's Most Selfless Acts of Heroism

Here are the most selfless acts of heroism that have ever happened in the Marvel Cinematic Universe. As a result of their world-building over the last 11 years, Marvel Studios has a rich library of beloved characters at their disposal. It all started with Iron Man, but they've seen Captain America, Thor, Black Panther, Spider-Man, Captain Marvel, the Guardians of the Galaxy, and many more join him as the mightiest heroes the MCU has to offer.

Every adventure in the Infinity Saga managed to build towards a major moment of heroism by the lead characters. Not all of them may have the same universe-altering stakes that came with Avengers: Infinity War and Avengers: Endgame, but each put the heroes in harm's way for the betterment of others. Through these moments, some of the MCU's biggest moments have happened.

With characters as heroic as Hulk, Doctor Strange, and Yondu, as well as 23 movies worth of material, it can be easy to forget all of the instances in which MCU characters saved the day. Screen Rant's latest video counts down the most selfless of these moments. As seen at the top of this post, the list includes iconic acts like Captain America crashing Red Skull's plane in 1945, Groot sacrificing his body to save the other Guardians, and many more. You'll need to watch the video to find out about them all, as we're going to highlight two of those mentioned below.



Aaron Taylor-Johnson's time in the MCU as Pietro Maximoff aka Quicksilver didn't last long, but he still managed to leave his mark. Once he and Scarlet Witch made their switch to be heroes and fight Ultron, it appeared he'd be around for many movies to come. But, when he saw Hawkeye saving a young Sokovian boy and Ultron's attack on them, he knew he had to act. Quicksilver pushed them out of the way and took all of the gunfire himself. The heroic moment ended with his death, and it's unlike many of the other sacrifices in the MCU. Instead of putting his life on the line to save the entire universe or just Earth, Quicksilver died to save just two lives. That's true heroism right there.


Iron Man

On the complete opposite end of the spectrum, Robert Downey Jr.'s already iconic sendoff to Tony Stark aka Iron Man is one of the grandest acts of heroism ever displayed in the MCU. He had already proved he was no longer the guy who would find an easy way around a difficult scenario in The Avengers, but this was even greater. Tony knew the second Doctor Strange held up his index finger that this act would be the end of him, but he did it anyway. He used the power of all six Infinity Stones and snapped his fingers to wipe out Thanos and his entire army. Tony sacrificed his life to preserve the family he recently found with Pepper and Morgan, ensuring that they and the rest of the universe remained intact.
