The worldwide release of Avengers: Endgame is just around the corner, and fans are hungry for details. It shows in the way things like minor toy releases fall under intense scrutiny, or the recent Disney shareholders meeting receiving an unusual amount of attention, despite the fact that no major Endgame information was released.

Now that Marvel Studios has surprised the world with an unannounced a trailer debut, prepare to see a new wave of theories floating around revolving around how the Avengers will defeat Thanos and restore everyone that was wiped from existence by the Mad Titan's universe-wide Decimation.

The trailer includes new clips and moments that should excite everyone, and perhaps even put some fan theories to rest. Familiar heroes finally meet newcomers, wild new action scenes tease the movie's big moments, and it's all supposed to take place within the first 20 minutes of the film, according to directors Joe and Anthony Russo.

Let's break it all down...

A TRIP DOWN MEMORY LANE

Avengers-Endgame-Trailer-Iron-Man

The first half of the trailer features a collection of black and white clips from Iron Man, Captain America and CA: Civil War, and Thor as the voices of Tony Stark, Peggy Carter and Thor are heard. Tony's speech seems to be aimed toward Pepper Potts, as he reminisces about his experience in the cave where he was held captive by the Ten Rings, saying, "It seems like a thousand years ago."

We see how far he's come in his superhero journey, but any sense of hope is snatched away (for now) when the trailer shows us Tony trapped in the Guardians of the Galaxy's old ship, The Benatar. "I know I said no more surprises," he intones, "but I was really hoping to pull off one last one," as if to say that he's exhausted all his options.

Of course, the fact that Steve Rogers and Thor were going to unite with the rest of the Avengers was never in question, and the speeches accompanying their respective montages focus on the theme of struggle and loss as the clips turn into a brief recap of the events in Avengers: Infinity War.

CLINT'S FAMILY

Hawkeye and family in Avengers Endgame

Shots of Hawkeye are interspersed throughout the first half of the trailer, and some of them may not be what fans were expecting. One clip in particular features Clint Barton apparently coaching his daughter in an archery lesson. She aims and hits the bullseye, possibly a hint of who she might become in Phase 4 of the Marvel Cinematic Universe.

What's saddening is the fact that this is almost certainly confirmation that Clint lost his family as a result of the Decimation, leading to his reinvention as Ronin, the alter-ego revealed in earlier trailers. We see his melancholic reunion with Black Widow in what appears to be Japan before he's shown again later in the trailer, at Avengers headquarters with a new haircut.

SCOTTY DOESN'T KNOW

Our first glimpse of Scott Lang shows the reluctant superhero wandering around a suburban neighborhood, shocked by the number of missing posters stapled to a post. The last time we saw him he was trapped in the Quantum Realm after the Decimation claimed Hank Pym, Hope Van Dyne and the recently rescued Janet Van Dyne in the post-credits sequence of Ant-Man and the Wasp. No one was left to get Scott back out.

The fact that Ant-Man will join the Avengers for an epic battle against Thanos was never in doubt -- it was only ever a matter of when and how. It's likely that the moment shown in the trailer takes place soon after Ant-Man returns from the Quantum Realm, when he begins to discover everything that happened since his disappearance.

Following brief glimpses of battle and travel sequences, we see Rocket and Rhodey teaming up for a fight. Rhodey has a new suit, one that's significantly bulkier than the armor he's used in the past. Rocket seems to be sporting a new outfit as well, complete with a set of matching goggles.

The environment around them is dark and difficult to see. They could be anywhere, fighting anything. Whatever they're doing there, they may not be doing it for very long considering the Russo brothers' claim that the marketing will only use the first twenty minutes of the film.

AVENGERS ASSEMBLE

After a rapid montage of vague action clips, we see the Avengers united once again. Cap is leading them, followed by Ant-Man and Nebula, War Machine and Hawkeye and, finally, Black Widow and Tony Stark, effectively squashing any theories about Tony meeting his end in space.

The clip also showcases the Avengers in all-new uniforms. Several theories out there postulate that these suits will be used for entering the Quantum Realm, and through it, travel through time itself. There has been a lot of speculation surrounding the new uniforms, much which stems from action figures and LEGO sets. While the Russo brothers have stated that 99 percent of toy leaks are fake, it appears that some of them were spot on.

There are two members of the Avengers missing in that slow motion march, but the trailer hasn't forgotten them.

STRONGEST AVENGER(S)

In the final clip of the trailer, we see Captain Marvel out of uniform. Thor approaches her and stretches his hand out as he summons his hammer, Stormbreaker. The weapon hurtles through the air, right past Carol's head and into the god of thunder's grasp, but the intergalactic hero doesn't flinch, she just smirks. Thor notices and says to everyone around them -- Natasha and Rhodey -- "I like this one." There are plenty of characters fans are eager to see unite and the moment in which the two strongest Avengers meet is definitely one of them.

Despite the fact that virtually everyone knew that Captain Marvel would appear in Avengers: Endgame, the character was absent from past trailers, in fact, it's entirely possible that she was edited out of trailer clips for the sake of secrecy. Now that her solo film, Captain Marvel, has been released, we're likely to see her more and more in marketing for the upcoming Avengers: Endgame.
