Remember me
Now that Marvel Studios has finally debuted the official trailer for Avengers: Doomsday, it's time to rank every Avengers movie's first main trailer to determine which is best. The Avengers movies have always been the biggest that the Marvel Cinematic Universe has to offer, and that's made the start of their respective marketing campaigns global events that draw plenty of eyeballs and elicit many reactions and conversations.
That's no different than the debut of Avengers: Doomsday's main trailer. While Marvel released four character-focused teasers in late 2025 through early 2026, they did not give much insight into the actual movie. Much of the multiverse crossover event is still under lock and key, with Marvel working especially hard to preserve surprises and spoilers until the movie's December 18, 2026, release date. But it still gave audiences the best look yet at the Avengers' fifth team-up.
Seeing the Avengers, Fantastic Four, and X-Men together on-screen for the first time is special, but how does it stack up to what's come before? The Avengers, Avengers: Age of Ultron, Avengers: Infinity War, and Avengers: Endgame all have memorable trailers; hardcore MCU fans will always remember what it was like to see each for the first time. Some have aged better than others, though.
5 The AvengersThe first official trailer for The Avengers will always hold a special place in people's hearts for it offering a proper look at Iron Man, Captain America, Thor, Black Widow, Hulk, and Hawkeye interacting. Perhaps it's the 14 years that have come since its arrival and the evolution of marketing campaigns or a result of Disney not yet being responsible for the cut, but The Avengers' trailer just doesn't quite hit as hard nowadays.
It does have the benefit of showing the MCU's first franchises joining forces in such a crossover for the first time, as well as offering first looks at memorable sequences like Bruce Banner transforming into Hulk or Tony's rebuttal that he's still a genius, billionaire, playboy, philanthropist without his suit of armor. And while it gives glimpses of the action, there is no real standout sequence offered here.
We don't even get a look at all the original Avengers members together. Instead, there's an overreliance on slow-motion shots, quick cuts, and narration. And while Nine Inch Nails' "We're In This Together" works well as a song choice, it gives the trailer a specific tone that is not really a reflection of what The Avengers would be. For those reasons, it comes in last.
4 Avengers: DoomsdayAvengers: Doomsday slots into fourth after having a cool trailer, but one that doesn't quite reach the epic heights of previous first looks. The footage strikes a very serious tone, with Thor speaking over the majority of the footage about how dangerous a threat they all face, and focuses on showing glimpses of most of the expansive cast while teasing a few of the film's action sequences.
Doctor Doom stopping Stormbreaker with his fingers is meant to be the trailer's big moment, but whether its because it feels reminiscent of Thor attacking Thanos in Infinity War or a lack of build up for Doom's arrival, it fails to fully land the way it needs to. Additionally, Marvel ends the trailer by treating Steve Rogers' return as a big reveal, but that comes up short since he was the star of the first Doomsday teaser.
The highlights of the trailer are seeing the various sides of the MCU multiverse come together. It is exciting to see the Fantastic Four meet the Wakandans and Avengers. Shang-Chi and Yelena Belova fighting Gambit and Mystique is also something new, which is what Doomsday needs. But the trailer leaning on Thor, Steve, and Robert Downey Jr.'s Doom (all original Avengers) makes it come across as more familiar than fresh.
3 Avengers: Age Of UltronThe official trailer for Avengers: Age of Ultron comes in the middle of the pack for this ranking. I can vividly remember watching this for the first time and the widespread excitement that it created. For the most part, Age of Ultron's trailer has aged rather well and still works as a great piece of marketing for Ultron's MCU debut.
The Avengers' AI robot villain is the real standout of the trailer. His creepy introduction leads directly into a rendition of "I've Got No Strings" that helps set the mood rather well. Even without any scenes of Ultron in action, Age of Ultron's trailer establishes him as a villain to be feared, with him saying "There are no strings on me" a great capstone to the footage.
While it does fall prey to an overreliance on slow-motion shots like Joss Whedon's previous installment, it gets major points for showcasing the brutal Hulk vs Hulkbuster fight. Their punches colliding near the end is one of the most exciting aspects of any Avengers trailer. And while Marvel manipulated fans a bit with the shot of Captain America's shield being broken in half, the trailer overall is really great.
2 Avengers: EndgamePerhaps the most anticipated trailer in MCU history, the first glimpse at Avengers: Endgame promised an epic and emotional conclusion to the Infinity Saga. There is a real sense of desperation and despair among the Avengers conveyed in the trailer that sets the perfect tone for the story to come.
What's most impressive about the Avengers: Endgame trailer is that it does all this without showing any action sequences. One would've thought Marvel would want to tease the huge scale and scope, but they hold back on everything. Yet, that doesn't stop the trailer from making the movie look exciting or establishing the stakes.
Rather than hinge itself on a few major, exciting shots, Endgame makes Ant-Man's arrival the big surprise. It was a perfect way to tease the time-traveling Quantum Realm story to come without explicitly confirming anything, including the five-year time jump.
Since everyone was already locked in to see Endgame no matter what, Marvel didn't need to show its true cards at this point. Keeping the debut trailer focused on how the characters are feeling after Infinity War was a brilliant decision.
1 Avengers: Infinity WarOn the flip side of Endgame's more character-focused, less showy trailer is the first Avengers: Infinity War trailer. Marvel Studios pulled out all the stops to show audiences why this was going to be the biggest MCU movie to date from the beginning of the marketing campaign. The result is not only the best first trailer for an Avengers movie but one of the best MCU movie trailers ever.
Redoing Nick Fury's "There was an idea..." speech from The Avengers with Fury, Iron Man, Vision, Thor, and Black Widow at the start not only worked as a great callback but also as a perfect way to set the stage for Thanos' proper introduction. The voiceover that the Mad Titan provides after that really makes you feel the weight of his arrival, and the footage of him collecting Infinity Stones, punching Iron Man, and body-slamming Spider-Man makes it even clearer.
The only real qualm with Infinity War's trailer is the trailer-made shot of Captain America, Bucky, Black Widow, Okoye, Black Panther, Hulk, Falcon, War Machine, and an army of Wakandans running into battle. The shot was never intended to be in the movie and was created specifically for marketing purposes. While it might annoy some that it isn't in Infinity War's final cut, it does accurately set up the final battle in Wakanda — sans Hulk's presence.
Otherwise, it is still a total blast to see these characters come together in this fashion, especially when Thor meets the Guardians of the Galaxy at the end, and it was a hype-building piece of marketing when it debuted in 2017. This is the bar that Avengers: Doomsday's marketing will be chasing going forward.
