The threat of major character deaths has been one of Avengers: Infinity War's longest and most ominous shadows since the promotional campaign started in earnest last year. We've known for a long while now that not everyone was going to make it out alive and, well, those threats proved to be pretty darn legitimate.

So let's not beat around the bush here: you came for spoilers, so spoilers are what we've got for you. Here's a complete casualty list for Infinity War -- proceed at your own risk.

Infinity War's casualties can be divided up into two major categories: on-screen deaths, and those who fell victim to Thanos's ultimate, Infinity Stone-powered will. Those who fall into the latter category are a pretty interesting case -- not just because they, rather than "dying," seem to crumble into dust and fade out of existence (something surely to be followed up on in next year's fourth Avengers film), but because of exactly which characters they include among their ranks.

Heimdall

Infinity War's first victim came from a surprising quarter. Seeing as how a huge chunk of Asgard -- including the Warriors Three -- were massacred during last fall's Thor: Ragnarok, named Thor side characters have been at a premium lately. But apparently their numbers are only going to continue to dwindle. Heimdall (Idris Elba) sacrificed himself to use the very last bit of Bifrost magic he could muster to send Bruce Banner to Earth. He met his end at the hands of Thanos, who impaled him with Corvus Glaive's scepter.

This was Heimdall's fourth feature in an Marvel Cinematic Universe movie.

Loki

Perhaps slightly less surprising than Heimdall but, if anything, more devastating, Loki (Tom Hiddleston) was the second life claimed. After an MCU tenure dating back to 2011's first Thor movie and including a major villain feature in Avengers, Loki's arc has been complex and multifaceted, garnering him a die-hard fan base. Still, popularity aside, with his most recent turn of heart in Thor: Ragnarok in the books, it seems as though it was decided his story has been told as completely as it could be.

Loki was killed by Thanos and this time -- as Thor himself later explains -- it seems like it's going to stick.

Loki has been featured in five of the MCU's movies.

Gamora

Gamora's (Zoe Saldana) status as one of Thanos' "daughters" has had her in the crosshairs from the beginning, but knowing that she's in danger and actually seeing that danger come to fruition are two very different things.

Gamora's death served as Thanos's sacrifice -- the cost he had to pay to retrieve the Soul Stone from the mysterious, liminal planet Vormir. Though there may be more to the story than just tossing her off a cliff in a ritual -- we see the young Gamora once more before the end of the film, apparently trapped in the orange-tinted Soul World inside the stone, something that may mean she's got a chance to return.

This was Gamora's third outing in the MCU.

Vision

Like Gamora, Vision's (Paul Bettany) been living on borrowed time for a while now. The Mind Stone that created him and powers him has obviously been on Thanos' wishlist, and he certainly doesn't care whether or not Vision survives the process of removing it.

... and, well, he doesn't. Despite the team's valiant effort (ultimately headed by Black Panther standout Shuri) to figure out a way to keep Vision alive without the Stone in his forehead, Thanos still gets exactly what he wants in the end, and poor Vision doesn't make it.

This was Vision's third major movie role.

The Entire Black Order

Maybe the least surprising death to be found in Infinity War was the entire four-person roster of Thanos' Black Order, streamlined for the MCU as Corvus Glaive, Ebony Maw, Proxima Midnight and Cull Obsidian ("Black Dwarf" in the comics). All four of them met their own unique, grisly fates surprisingly easily at the hands of various Avengers teams. Ebony Maw was sucked into space thanks to Strange, Spider-Man and Iron Man. Promixma was caught in the gears of one of her own death machines thanks to Scarlet Witch ("that was really gross"), Cull Obsidian was propelled by Hulkbuster armor parts and torn in half by a Wakandan energy shield, and Corvus Glaive was speared through with his own Glaive by Vision.

This was the Black Order's first (and, apparently, last) appearance in the MCU.

Bucky Barnes

The first person to be seen suffering the effects of Thanos's reality-warping finger snap is none other than Bucky Barnes, who makes it about two steps towards Steve Rogers before he crumbles into ash. ("... Steve?") Apparently poor Bucky just hasn't suffered enough already, so naturally he was one of the Avengers to get the short straw when it came to the balancing of the universe.

This was Bucky's sixth appearance in the MCU, including his post-credits scene in this year's Black Panther.

Falcon

One of Infinity War's more subtle touches was an emphasis on the friendship forming between Sam Wilson and James Rhodes, who had previously been on opposite sides during Civil War. It seems like they've set their differences aside now, however -- and just in time for to really drive home the heartbreak.

As Thanos' will manifests across the planet, Sam is one of the disintegrating victims, crumbling to dust as Rhodey calls out looking for him. Needless to say, he never finds him.

This was Sam's fifth MCU movie.

Black Panther

Shockingly, another one of Thanos's victims is none other than king T'Challa himself, who fades into ash as he tries to re-group with his Dora Milaje General Okoye. He makes it far enough to help her up before he begins to crumble, leaving Okoye helpless to watch as her king vanishes into thin air.

T'Challa's "death" raises more than a couple eyebrows, considering a Black Panther 2 has all but been confirmed after the massive success of his first solo film. This was his third MCU outing.

Groot

Teenage Groot got his fair share of heroic moments, despite otherwise being pretty invested in his Defender video game during Infinity War -- but all the heroism in the world wasn't enough to save him from Thanos's cosmic entropy. Groot faded away, leaving absolutely nothing behind -- not even a new sapling to start all over with. This officially puts Groot in the esteemed company of the handful of MCU characters who have actually died more than once.

This was Groot's second death, and third MCU feature.

Scarlet Witch

Wanda Maximoff's role in Infinity War was rather emotionally tumultuous. From having to effectively kill her lover, Vision, to having that sacrifice ultimately be completely in vain, it's pretty safe to say Wanda has seen better days. To cap it all off, she was one of Thanos's victims in the end -- so not only did she have to watch Vision die twice, she didn't survive long enough after him to even get a chance to mourn.

This was Wanda's fourth appearance in the MCU, including her post-credits introduction in Captain America: The Winter Soldier.

Star-Lord

The Guardians of the Galaxy were hit pretty hard by Infinity War, to say the absolute least. Already grief-stricken by the loss of Gamora, Peter Quill was one of the unlucky few to fall victim to Thanos's balancing act. Stranded on Titan with a new team who remained all but strangers to him, Star-Lord crumbled into nothingness.

This was Peter Quill's third MCU movie.

Mantis

Continuing the Guardian's high casualty rate, relative newcomer Mantis was next to go in Thanos's great purge. The most recent addition to the Milano's ragtag crew, Mantis debuted in Guardians of the Galaxy Vol. 2, making her one of the most recent characters to bite the literal dust in Infinity War. She was "balanced" right out of existence (her second major run in with the reality-warping Infinity Stones in the movie) on the planet Titan alongside Quill and Drax.

This was only Mantis' second MCU film.

Drax

The final Guardian to pay the ultimate price in Infinity War was Drax the Destroyer, who perished beside his teammates after the costly battle on the planet Titan. Drax spent Infinity War barely able to contain his own personal beef with Thanos for the destruction and massacre of his home planet and family -- a beef he, unfortunately, obviously did not get to settle before he was disintegrated.

This was Drax's third appearance in the MCU.

Doctor Strange

Stephen Strange was one of the more surprising casualties of Infinity War for a few reasons, not the least of which being he remained the only human Avenger to have control over an Infinity Stone for the majority of the movie -- and the Time Stone, at that. In a shocking movie, Strange sacrificed the stone to save the life of Tony Stark, and then immediately paid for his choice when he was one of the unfortunate victims to vanish when Thanos completed the Gauntlet.

Interestingly, however, Strange was also the one Avenger who, we can assume, had some idea of how to win. Before sacrificing the stone, he used its power to look into alternate futures where he saw millions of different outcomes and only one way to win. Will his sacrifice play part of that winning scenario? We'll have to wait a year to find out.

This was Strange's third MCU appearance.

Spider-Man

In one of the most emotionally brutal Thanos-related deaths, young Peter Parker fell victim to the Gauntlet's magic while the dust settled after the battle on Titan. As if watching the bright eyed, plucky Peter Parker die wasn't rough enough, he did so by collapsing into Tony Stark's arms and, terrified, practically begging, that he didn't want to "go," all while Tony watched helplessly on.

Like T'Challa, Peter's disintegration was a major surprise, considering he's been confirmed for a second movie -- one that has already been confirmed Kevin Feige to start filming in July. So, no matter how cold the comfort, maybe don't worry too much about Peter's future.

This was Spider-Man's third MCU feature.

Maria Hill

The deaths didn't stop after the credits rolled in this one. In Infinity War's only post-credits scene, we see S.H.I.E.L.D. mainstay Maria Hill, speeding through the streets of a New York City that is descending into chaos as Thanos' victims disappear one by one, including people on the road, flying helicopters -- really, you name it. The city is melting down.

Unfortunately, that also includes Maria herself, who only gets the briefest instance to survey her surroundings before she too crumbles into nothingness.

This was Maria's fourth MCU appearance.

Nick Fury

Hill wasn't the only surprise post-credits return for Infinity War, and she wasn't alone as she scrambled to figure out just what the hell was going on. Nick Fury, who apparently has been keeping up the pace with trying to rebuild and re-establish S.H.I.E.L.D. since Age of Ultron, was right there with her.

As he watched Maria disappear, he was just barely able to send a very specific distress signal out using a device that looked something like a beeper. Thankfully, as he crumbled, he dropped it, leaving it safely non-disintegrated on the ground.

This was Nick's eighth MCU appearance.

Will any of these characters make it back to the land of the living? For both fictional and real-world reasons, it's a safe bet -- but for now, exactly who and how remains a mystery until the fourth Avengers film, which is scheduled to hit theaters on May 3, 2019.
