The Marvel Cinematic Universe is known for making its stories emotionally impactful, and the Guardians of the Galaxy films are a prime example, filled with genuinely sad moments. This emotional impact reached its peak in Avengers: Infinity War and Avengers: Endgame, which featured some of the most shocking and heartbreaking character deaths ever seen in a superhero movie. While those films focused on the loss of established heroes, James Gunn’s approach in Guardians of the Galaxy was unique – he could powerfully affect audiences even with the deaths of characters they hadn’t fully connected with.
From heartbreaking losses of family members to the deaths of iconic heroes, here are seven moments in the Marvel Cinematic Universe that truly devastated fans.
7) Meredith Quill
The first Guardians of the Galaxy film began with a surprisingly emotional scene showing Peter Quill’s childhood. In 1988, young Peter watched his mother lose her battle with cancer. Although she wanted to say goodbye, Peter, being a child, couldn’t cope and ran away from the hospital.
It absolutely broke my heart watching Peter’s story unfold. He never got to say goodbye to his mom, and she passed away without him – that’s when he was taken by Yondu and left Earth. Seeing his mother, Meredith, show him so much love, then watching the pain on her face when he ran away… it was devastating. It really explained why he struggled so much growing up and became the flawed hero we know. And then, finding out in the second movie that his dad, Ego, was responsible for Meredith getting sick? That just made her death even more tragic and fueled Peter’s anger and pain. It’s a really powerful part of his journey.
6) Jane Foster
Jane Foster first appeared in the movie Thor, but her role became smaller in Thor: The Dark World. She returned in Thor: Love and Thunder with a surprising twist: she was battling cancer. The movie showed her searching for Mjolnir, hoping the Asgardian hammer could heal her, after it had been brought to Earth.
She was transformed into a female counterpart of Thor and bravely fought alongside him against Gorr. Unfortunately, the power she used accelerated her existing cancer, and she died during the battle. It was a heartbreaking moment as she sacrificed herself for the greater good, held in Thor’s arms.
5) Loki
Loki’s transformation throughout the Marvel Cinematic Universe has been captivating. He began as a clear villain in the first Thor movie and continued that role in The Avengers. Later, he became an uneasy ally in Thor: The Dark World, and eventually evolved into a hesitant hero in Thor: Ragnarok. His growing popularity led Marvel Comics to also portray him as a good guy, which made his eventual death all the more impactful.
It was incredibly surprising when Thor, Loki, and Hulk appeared to have rescued the Asgardians, only for Avengers: Infinity War to begin. Thanos then arrived and brutally defeated Thor, ultimately killing Loki right before Thor’s eyes. Loki’s final attempt at heroism before his death made the scene particularly heartbreaking. While he didn’t remain dead permanently, Loki’s death was a truly shocking and tragic moment in the film.
4) Black Panther
The death of Black Panther deeply affected fans, and the real-life passing of actor Chadwick Boseman amplified the emotional impact far more than the events of the movie itself. While T’Challa’s death in Black Panther: Wakanda Forever was already a moving moment, knowing Boseman had passed away made it even more heartbreaking. The film respectfully portrayed T’Challa’s funeral, but it was still a very emotional scene for many viewers.
The Marvel Cinematic Universe sparked debate when it chose not to replace the actor who played T’Challa, instead writing his character, the King of Wakanda, out of the story with a death. This allowed the role of protector to pass to Shuri, and the storyline continued without him. While there’s speculation that T’Challa will return with a new actor in the future, Black Panther: Wakanda Forever served as a poignant farewell to a much-loved character.
3) Aunt May
Spider-Man has faced a lot of loss throughout his comic book history, starting with Uncle Ben and Gwen Stacy, and continuing with many others. When Spider-Man joined the Marvel Cinematic Universe, the story began with his uncle already gone, and Peter Parker was already operating as Spider-Man. Despite this, he still experienced significant emotional trauma, losing both his mentor, Iron Man, and his Aunt May.
Aunt May’s death in Spider-Man: No Way Home was a huge shock to audiences. In the comics, she’s always been a constant for Peter Parker, someone he even sacrificed his marriage to protect. After so much loss in the films, losing Aunt May felt like a breaking point, suggesting it might have been the end of Spider-Man’s journey as a hero.
2) Black Widow
Natasha Romanoff’s death in Avengers: Endgame was both surprising and controversial. Some fans were upset by her sacrifice, as she gave her life to save Hawkeye. This occurred while they were seeking the Soul Stone, guarded by the Red Skull, and she ultimately traded her life for it, ensuring the universe could be saved.
Natasha Romanoff’s death was a deeply sad moment, making it clear that not all of the original Avengers would survive. The tragedy was further complicated by the introduction of Yelena Belova in the Black Widow movie (set earlier in time), as Natasha’s death deeply affected Yelena, leading her down a dark path and even prompting her to try and kill Hawkeye, whom she held responsible. Black Widow was a fan favorite, and her death was truly impactful.
1) Iron Man
The most shocking death for Marvel Cinematic Universe fans happened when Iron Man sacrificed himself to defeat Thanos and save Earth. While it provided a fitting end to his character arc, the scene – with Spider-Man’s grief and Pepper Potts’ heartbreaking acceptance – was incredibly emotional and devastating to watch.
Iron Man’s funeral was a truly perfect scene, marking the end of the Infinity Saga. It brought together all of Tony Stark’s friends, allies, and teammates for a final tribute. The emotional impact of his death deeply affected MCU fans and highlighted just how strong the preceding movies had been.
