Avengers Doomsday Could Have a Major Death — Anthony Mackie’s Hint About Steve, Bucky and Sam Has Fans Worried

Avengers: Doomsday is already shaping up to be one of Marvel’s biggest and most unpredictable movies, but one question is becoming impossible to ignore: who actually makes it out alive?

With the Marvel Cinematic Universe bringing together an enormous lineup of returning heroes, the stakes are expected to be higher than ever. And now, Anthony Mackie has added even more fuel to the speculation surrounding the future of Sam Wilson, Bucky Barnes and Steve Rogers.

Mackie’s comments have fans wondering whether one of the most important Captain America-related characters could be heading toward a heartbreaking fate.

Anthony Mackie’s Avengers Doomsday Hint Has Fans Talking

Anthony Mackie’s Sam Wilson is now firmly at the center of the MCU following Steve Rogers’ decision to pass the Captain America mantle to him.

That makes Mackie one of the key stars to watch as Avengers: Doomsday moves toward its massive conflict.

But when the conversation turns to Steve Rogers and Bucky Barnes, things become much more interesting.

The three characters share one of the MCU’s most complicated histories. Steve and Bucky go all the way back to the beginning of their friendship, while Sam eventually became one of Steve’s closest allies and the hero chosen to carry the shield.

That history makes any suggestion about their possible future in Doomsday particularly worrying.

Could Steve Rogers Die in Avengers Doomsday?

Steve Rogers’ return has already created huge excitement among Marvel fans, but his involvement also raises an obvious question: why bring Steve back now?

Chris Evans is expected to appear in Avengers: Doomsday, giving Marvel an opportunity to reunite the original Captain America with Sam Wilson and Bucky Barnes.

But Marvel has never been afraid to put its biggest characters in danger.

If Doomsday is designed to establish a new era for the Avengers, Steve’s return could potentially be connected to one of the movie’s biggest emotional moments.

That does not mean Steve Rogers is confirmed to die.

However, Mackie’s comments have made fans question whether Steve’s return could come with a price.

Bucky Barnes Could Also Be in Serious Danger

Bucky Barnes has survived an extraordinary amount throughout the MCU.

From being presumed dead to becoming the Winter Soldier and eventually finding a path toward redemption, Bucky has become one of Marvel’s most recognizable supporting heroes.

His relationship with Steve remains one of the emotional foundations of the Captain America story.

That is precisely why a possible confrontation involving Steve, Bucky and Sam could be so powerful.

If Avengers: Doomsday truly pushes these characters into an all-or-nothing battle, Marvel could use their shared history to create one of the movie’s most emotional sequences.

For now, however, there is no confirmed information establishing that Bucky dies.

What About Sam Wilson?

Sam Wilson may have the biggest reason to survive.

As the current Captain America, Sam represents the future of the franchise. His story is still developing, and Marvel has spent considerable time establishing him as a hero capable of carrying the shield without simply becoming another version of Steve Rogers.

That makes Sam’s potential death less likely from a storytelling perspective — but anything is possible when Marvel starts dealing with a massive multiverse-level threat.

If Sam does survive Doomsday, the experience could completely change his role within the MCU.

And if another Captain America-related character falls, Sam could be forced to carry even more emotional weight afterward.

Avengers Doomsday Could Change the MCU Forever

The biggest reason fans are nervous is the scale of Avengers: Doomsday.

Marvel is assembling an unusually large group of characters for the movie, creating the perfect setup for major sacrifices and unexpected character exits.

The film also sits at a crucial point in the MCU's larger story, meaning its consequences could extend far beyond a single Avengers movie.

That is why speculation about deaths has become such a major part of the conversation.

But there is an important difference between fan theories and confirmed spoilers.

At this stage, rumors about Steve, Bucky or Sam should not automatically be treated as confirmation of anyone’s death.

Who Is Most Likely to Die in Avengers Doomsday?

If Marvel follows the traditional structure of a huge Avengers event movie, the characters most at risk could be those whose stories have already reached a natural turning point.

That does not necessarily mean Steve, Bucky or Sam.

In fact, their complicated history could be more valuable to Marvel alive than dead — particularly with Sam now serving as Captain America.

The real mystery is whether Doomsday will use Steve Rogers’ return to close one chapter of Marvel history or open another.

And that is what makes Anthony Mackie’s hint so intriguing.

The Steve Bucky and Sam Reunion Could Be the Emotional Core

Regardless of who survives, bringing Steve Rogers, Bucky Barnes and Sam Wilson into the same story could deliver one of the MCU’s most emotional reunions.

Steve represents the legacy.

Bucky represents the past.

And Sam represents the future.

Putting all three together in a movie built around an enormous threat gives Marvel a chance to explore exactly what the Captain America legacy means after Steve Rogers.

It also creates the possibility of a genuinely emotional farewell — even if Marvel ultimately decides not to kill any of them.

So Who Dies in Avengers Doomsday?

Right now, there is no reliable confirmation that Steve Rogers, Bucky Barnes or Sam Wilson dies in Avengers: Doomsday.

Anthony Mackie’s comments have certainly intensified speculation, but fans should be careful about treating hints, rumors and theories as confirmed plot details.

One thing is clear: with Steve back, Sam carrying the shield and Bucky still deeply connected to both characters, Marvel has created a storyline where the emotional stakes could be just as important as the action.

And if Doomsday really is preparing to say goodbye to one of these characters, Marvel may be saving that reveal for the biggest possible moment.

The question isn't just who will fight Doctor Doom. It's who will still be standing when the battle is over.
