Superhero deaths are a dime a dozen in the comics, yet so far, Marvel Studios have been reluctant to take the plunge and kill off one of their main characters. The closest we came was when Loki murdered Agent Coulson in the first Avengers film, but it didn't take too long for Phil to pop back on our screens in the TV show Agents of S.H.I.E.L.D.
Thanos's grand scheme is to collect all of the Infinity Gems, granting him immeasurable power, and it just so happens that one of these is currently located in the Vision's forehead.
It's unlikely that the Vision will survive without the power of the mind gem, making him the most obvious candidate to die first, although he is an android, so there's always the chance that the Avengers could just rebuild him.
Those expecting Captain America: Civil War to remain faithful to the comics were surprised when Steve Rogers actually survived until the end of the credits, but it's likely that Marvel did that precisely to surprise audiences and kill him off in Avengers: Infinity War.
Chris Evans has stated before that he would like to move away from acting and work more behind the camera. Marvel have already lined up potential replacements for Steve Rogers in the form of Bucky and Falcon, so the odds of seeing the broken shield from Stark's Avengers: Age of Ultron vision are high indeed.
Robert Downey Jr regularly claims that he's ready to leave the MCU for good, but then continues to agree to future appearances, such as his upcoming cameo in Spider-Man: Homecoming, leaving his future in the MCU questionable at best.
It's hard to deny how intrinsic Downey's performance has been to the success of the MCU, so it would be an extremely bold move if the studio did take him out for good, one that would hold real gravitas for audiences used to the temporary deaths seen in the comics.
The title of Thor's next film led many to believe that the Thunder God may not survive to star in his own post-credits scene, but the directors of Avengers: Infinity War recently let slip that Thor will indeed join his fellow teammates in the battle against Thanos.
However, Marvel may be pulling the rug out from under us here, keeping Thor alive throughout a movie called Ragnarok only to kill the seemingly immortal god at the end of Avengers: Infinity War. If anyone in the MCU has the firepower to take Thor out, it's Thanos.
Drax The Destroyer
The Avengers may be the focus of the battle against Thanos, but after the Russo brothers confirmed that up to 67 characters could appear in Avengers: Infinity War, it became safe to assume that the Guardians of the Galaxy will appear for the final fight.
Drax The Destroyer holds a personal vendetta against Thanos, who was responsible for the death of his family, so there's a chance that his reckless nature could lead to his untimely death.
While the focus so far has been on the heroes of the MCU, previous Marvel movies have had a habit of killing their antagonists by the time the credits roll round, so why should Avengers: Infinity War be any different?
Considering his immense power set, it's hard to imagine how the Avengers could defeat Thanos without taking him out for good. The Mad Titan is far too powerful to take alive and this ending would be rather fitting, reuniting Thanos with his one true love, Death itself.
Ok, we know what you're thinking, but hear us out.
In the original comics that Avengers: Infinity War is based on, Thanos actually succeeds, basically killing off the entire Marvel universe, so the Russo brothers may follow a similar path, destroying all of our beloved heroes at once. Obviously, such a move would be temporary, because, comics, but imagine the emotional impact that a scene like this could have.
