Cap's days in the MCU are numbered, that much is clear. Chris Evans recently told the New York Times he won't be back after Avengers 4, but that doesn't necessarily mean he won't actually be killed off in Infinity War and only appear in flashbacks or in a time travel situation in the next film.

The face of the franchise for the first three phases, the time has come for Tony Stark to move on. Robert Downey Jr. is 53 years old, and there hasn't been a solo Iron Man movie since Iron Man 3 five years ago. Infinity War could definitely be his swan song.

The android Avenger is likely in big trouble in Infinity War, since he has an Infinity Stone embedded in his forehead. Thanos is out to collect all the stones in the film, and if he obtains Vision's, it will likely kill the Avenger.

Like the other OG Avengers, Chris Hemsworth's contract is up after Avengers 4, according to USA Today, but he's seemed more open to returning to the franchise compared to Evans and Downey. Thor: Ragnarok definitely reinvigorated the Thor franchise, but no Marvel solo series has yet to go beyond three films, seemingly making the God of Thunder expendable.

Thor's brother could also be on his way out. He has an Infinity Stone, which he stole from Odin's vault in Ragnarok, and will likely be confronted by Thanos at the start of Infinity War (that was Thanos' ship that encountered Thor and company at the end of Ragnarok). He has a history with Thanos, and it's entirely possible he doesn't survive his next run-in with the Mad Titan.

Nebula is one of Thanos' adopted daughters (his least-favorite), and is currently out for revenge against him. Given that Thanos is considerably more powerful than she is, that may not work out so well for her.

The Archer Avenger is not even confirmed to appear in Infinity War, but if he does show up, he may not last long. The character has always been the least popular of the original six, and killing him off could raise the stakes without angering too many fans.

The only female among the original six Avengers, Black Widow is probably safe. She finally has her own movie in development, and killing her off beforehand wouldn't make much sense. However, she has no superpowers and will be more overmatched in Infinity War than ever before, and after playing the character for nearly a decade, Scarlett Johansson may feel it's time to move on.

Avengers don't get more expendable than War Machine. He almost died in Civil War, and has never really functioned as a character on his own — we know little about him outside of his interactions with his buddy Stark. With more Iron Man films unlikely, it's quite possible the increasingly-crowded MCU has no room left for Rhodes.

With a large-scale invasion taking place in Wakanda during Infinity War, it seems highly-likely that someone from that nation will perish defending their homeland. T'Challa, Shuri, and Okoye are all too important to the Black Panther franchise to perish, but M'Baku? He already had a complete redemption arc in Black Panther, so seeing him bite the dust in Infinity War would make sense.

The Avengers don't have many female heroes, so like Black Widow, she's probably safe. The one thing that could endanger her, however, is her connection with Vision. It's possible that Wanda dies trying to defend her Android boyfriend from Thanos, because as powerful as she is, she's no match for the most powerful being in the galaxy.

Drax, like Nebula, has it out for Thanos. He blames him for the death of his wife and daughter, and that rage could lead him to confront Thanos like he did Ronan in the first Guardians movie. That confrontation with the Kree radical nearly killed him, so Drax surely wouldn't survive a one-on-one fight with Thanos.

Idris Elba has made no secret of his disdain for appearing in Marvel movies, so he'd probably welcome his character's death. And since he's on the ship full of Asgardians that Thanos encounters at the start of Infinity War, there's never been a more likely time for Heimdall to head to Valhalla.

Like Vision and Loki, The Collector has (as far as we know) an Infinity Stone. Thanos is going to come for it, and it's probably not going to end well for Taneleer Tivan.

Gamora is arguably the second most important member of the Guardians after Star-Lord, so she's probably not going anywhere. Still, she is an adopted daughter of Thanos, and that connection could make her a target.

Hulk may not be eligible for a solo franchise (the character apparently has rights issues), and that may make him an unnecessary expense in Marvel's eyes. He's been relegated to supporting duty in Avengers films and, most recently, in Thor: Ragnarok, but with those franchises either ending or changing massively, there may not be room for Hulk in the future MCU.

Cap's friend is a strong nominee to take up the shield if Cap goes down, but it's not clear if Sam Wilson is popular enough to carry a franchise on his own, and that could put him in danger.

The other nominee to become the new Cap in case Steve Rogers is killed (both Bucky and Falcon have taken up the shield in the comics), Bucky certainly has a strong fanbase. He's also on the tail end of a redemption arc, though, and that could make him a prime target for a death that would leave fans reeling.

Is Nick Fury even in Infinity War? That's unknown for now, but his voice was featured in the first trailer. He hasn't popped up in a Marvel film since 2014's Captain America: The Winter Soldier, where he faked his own death, but the arrival of Thanos could bring him back to the land of the living — though it may be a short stay given how the MCU has gotten along just fine in his absence. He is confirmed to appear in next year's Captain Marvel, but since that film takes place in the '90s, that doesn't mean he'll survive Infinity War.

As you can see, there are cases to be made for numerous character deaths in Infinity War. And while it's hard to say which characters might die, it's virtually assured that at least some of the heroes above will meet their end in the film.
