With just over a month to go until Marvel's highly anticipated superhero mash-up Avengers: Infinity War arrives, a brand new trailer has just been released.

The final promo teases an epic battle between Earth's mightiest heroes, their superhero allies, and Thanos (Josh Brolin), the Mad Titan who seeks to combine the six infinity stones in order to complete the Infinity Gauntlet: a tool that will make him the most powerful being in existence.

The trailer obviously doesn't give away too much in the trailer. If one pays close attention, however, they'll find answers to the film's biggest questions, including which Marvel superhero dies in the upcoming film.

Gamora's Flashbacks Of Thanos

Thanos's adopted daughter Gamora (Zoe Saldana) has a lot of screen time in the trailer as she's the only one who knows about his evil plan.

"The entire time I knew him, he only ever had one goal," she says. "To wipe out half the universe."

In the trailer, Thanos can be seen walking next to a green-skinned Zehoberei girl. For those who don't know, the Zehoberei was an alien race that was completely wiped out by the Mad Titan, except for Gamora, whom he decided to adopt instead.

The new footage shows a close-up of a young Gamora holding the Marvel supervillain's finger, a reminder that Gamora had a dark past before she became a Guardian of the Galaxy.

Which Avenger Will Die?

At one point in the trailer, Thor (Chris Hemsworth) is completely at the mercy of Thanos with his head in the Mad Titan's grip and about to be crushed. It's possible that the hammer-wielding god won't make it out alive given that Hemsworth's contract expires after Part 2 of Infinity War and we already know that one Marvel superhero will die in the upcoming film.

Similarly, Captain America (Chris Evans) can also be seen going head-to-head with Thanos at the end of the trailer as he tries to stop him from crushing him with his giant hand. There is a lot of speculation that Cap will be the hero who sacrifices himself for the sake of humanity. After all, he did jump on a grenade in Captain America: The First Avenger.

From the looks of it, Iron Man (Robert Downer Jr.) isn't safe either. There is a shot of him being overpowered by Thanos's parademons before a scene that shows his suit of armor completely destroyed, leaving his face and upper body exposed to the Marvel supervillain.

"I hope they remember you," Thanos tells him, before making his next move.

Also, the fact that the actor's Marvel contract up makes it very likely that he won't survive the upcoming film.

Thanos Already Has Two Infinity Gems

The Mad Titan crushes a Tesseract to obtain the Space Stone: the blue-colored gem that allows for interdimensional travel.

Later, during his battle with Captain America, the purple-colored Power Stone can also be seen on his Infinity Gauntlet. The gem, which was first introduced to the Marvel Cinematic Universe in Guardians of the Galaxy, possesses the power to wipe out entire worlds.
