With a whopping cast featured in Avengers: Doomsday, and a threat to life itself that exists outside of half of the universe, but instead the entire multiverse – it’s worth taking a look at classic MCU characters set to feature that could end up dying in this fight against incursions, other worlds, and Doctor Doom.
Marvel: 10 Best MCU Sequel Movies, Ranked
Some sequels set in the Marvel Cinematic Universe have become iconic modern films, such as Guardians Of The Galaxy Vol. 3 and Avengers: Infinity War.
There are a few characters that could die in Avengers: Doomsday, and the MCU will never be the same without them. Much like how Avengers: Endgame saw the end of Iron Man, Black Widow, and Captain America, it’s likely that Avengers: Doomsday will force audiences to say a heartbreaking goodbye to some classic heroes.
7 Thor
The God of Thunder’s Time May Be Over After 8 Movies
- Played by: Chris Hemsworth
- Last Seen in: Thor: Love and Thunder (2022)
Chris Hemsworth’s Thor is really one of the biggest hearts and muscles of the MCU, and this character has been with audiences since Phase One. As the immortal God of Thunder, this Asgardian has suffered, and it’s doubtful that his suffering will be over. Thor is a great character, but how many more movies and universe-ending threats must he take before it’s too much for him?
Thor is extremely powerful, but how will he handle the knowledge of his brother’s fate as the God of Stories, burdened by his glorious purpose to contain the multiverse? Will he die saving him from Doctor Doom, or will he bite off more than he can chew to save not just a world, but a multiverse?
6 Professor Xavier
Charles Xavier Collects Death Like Trophies Across the X-Men Saga
- Played by: Patrick Stewart
- Last Seen in: Doctor Strange and the Multiverse of Madness (2022)
Charles Xavier is no stranger to death. In fact, he’s already died 3 times on-screen. Firstly in X-Men: The Last Stand (2006), secondly in Logan (2017), and thirdly in his MCU debut, Doctor Strange and the Multiverse of Madness (2022). With 3 deaths, it’s somewhat predictable to assume that Professor X is going to die, perhaps as a way to spur on the X-Men in or against the Avengers in their first live-action crossover.
Professor X’s wisdom and mental fortitude are essential to the X-Men, and his leadership helps inspire them to do good in a world that detests mutants. However, Xavier’s death could spur the X-Men, or perhaps even cause Magneto to descend further into villainy alongside Doctor Doom.
5 Bucky Barnes
The Winter Soldier’s Character Arc May Be Over
- Played by: Sebastian Stan
- Last Seen in: Thunderbolts* (2025)
Bucky Barnes has come a long way from Captain America’s best friend, turned brainwashed super soldier, and now congressman. This journey shows how Bucky has adapted to the modern way of American life and how he uses his trauma and the powers bound to it for the betterment of humanity. However, there’s only so much he can do, especially when the entire multiverse is threatened.
Marvel: 10 Best MCU Villains Who Became Heroes, Ranked
Not every villain is one-dimensional in the Marvel Cinematic Universe, with characters like Loki and Winter Soldier evolving into iconic heroes.
Bucky is easily one of the most beloved characters, so nobody wants to see him die, but his death could be the catalyst for consequences for Sam Wilson’s Captain America, who has bonded so deeply with Bucky over the years that seeing his death will inspire him to assemble the Avengers once more.
4 Sentry
The Ultra-Powered Hero, Wrestling with the Void
- Played by: Lewis Pullman
- Last Seen in: Thunderbolts* (2025)
The Sentry is one of the strongest heroes in the universe, so his appearance in Avengers: Doomsday is going to make things feel a little easy, considering he’s strong enough to fight Hulk into a stalemate, among other things. Sentry could pose a great threat to Doctor Doom, which is why Doom might make a play for Sentry’s darker side by bringing out the Void so that the Avengers have a liability on their hands.
The Sentry’s death could be an easy way to deal with how overpowered he is, and it could come at a tragic sacrifice as he attempts to take his own life to stop the Void, or causes the Avengers to fight him with all of their might.
3 Red Guardian
The Ever-Cheery Super Soldier
- Played by: David Harbour
- Last Seen in: Thunderbolts* (2025)
The Red Guardian is essentially Russia’s failed version of Captain America, except that Red Guardian developed great powers of strength that are only beaten by his large heart. While Red Guardian is set to appear in the Thunderbolts* (2025) and survive, as known by his announcement on the cast for Avengers: Doomsday, there’s still room for his demise in his third movie with his debut in an Avengers film.
Marvel: 10 Best MCU Characters, Ranked
Characters like Wolverine and Loki have become iconic pieces of superhero history as part of the Marvel Cinematic Universe.
Red Guardian could be killed off for a few reasons. Firstly, he’s pretty comedic, so killing him would sell the tone of a more serious event. Secondly, it’s a good catalyst to motivate the Thunderbolts and Yelena in particular, but it would also make sense for Red Guardian since he’s always hurling himself into dangerous situations to save those he loves.
2 Loki
The God of Stories Who Keeps the Multiverse in His Grasp
- Played by: Tom Hiddleston
- Last Seen in: Loki (2021-2023)
Loki has always been burdened by glorious purpose, but it took centuries to discover what that purpose was. Despite his love for his brother and his friends, Loki has left it all behind to control the multiverse, not as a conqueror, but as a guide. Loki acts as Yggdrasil, the world tree, keeping the ever-weaving stories born of an expanding multiverse alive as he sits in the forever and emptiness of time itself.
Loki’s fate is somewhat tragic, and since he’s holding the multiverse together, it seems likely that he will be involved in the plot somewhat. Will Doctor Doom disrupt the multiverse by killing Loki, or will something undo Loki’s purpose? Either way, an emotional reunion is deserved between Thor and Loki, who haven’t seen each other since Loki died in Avengers: Infinity War (2018).
1 Ant-Man
A Mighty Hero Who Might Be Too Small for the Fight Ahead
- Played by: Paul Rudd
- Last Seen in: Ant-Man and the Wasp: Quantumania (2023)
Ant-Man has received his own trilogy and was integral in the victory against Thanos in Avengers: Endgame (2019) thanks to the way time moves differently in the Quantum Realm. Yet, with a concluded trilogy and plans for a villain in Kang that didn’t go anywhere, it seems like Ant-Man’s story is pretty much finished, so where exactly can he go from here other than comic relief with fun powers that involve silly items getting big or small?
Perhaps Ant-Man would be the perfect victim to kill off, showing how Doctor Doom doesn’t mess around, and that Avengers: Doomsday isn’t going to pull its punches when it involves some of the most beloved heroes in the MCU.
