After months of anticipation and weeks of hype and fake-outs, the first trailer for the recently titled Avengers: Endgame was released. The brief reveal focuses on a few of the main survivors of the "snap" (now known as The Decimation) following the events of Avengers: Infinity War, revealing a stranded Tony Stark, a beardless Captain America alongside Black Widow, the return of Scott Lang's Ant-Man, and the debut of Hawkeye's new look. Fans even got a brief glimpse at a peaceful scene featuring Thanos, following his victory that left half of the universe dead.
The trailer offered a bit of hope and teased some of what fans needed to see after the emotional ending of Infinity War. However, there were a number of moments and characters we were hoping to see in the trailer that we've learned about over the last year that didn't appear. Leaked set photos like the ones that first spoiled the Ronin costume that Hawkeye adopts or casting announcements that spawned numerous fan theories and discussions had fans expecting some things left unseen in the first look at Avengers: Endgame.
The official Marvel Cinematic Universe debut of Brie Larson's Captain Marvel might not happen until her own film drops in March, but her presence in the Endgame trailer was missed. Following the post-credit tease in Infinity War that featured Nick Fury's now-infamous beeper with the Captain Marvel logo, her inclusion in the next Avengers film has not been a secret. While it's easy to see why the first trailer focused mostly on the original members of the team, fans were still disappointed to miss out on another look at Captain Marvel after the hype built up from the last trailer.
Tony Stark featured heavily in the first trailer, which makes sense considering his leading role in the first phases of the MCU. Unfortunately, Stark is limited to his post-Titan adrift in space lifestyle, which is not what was seen during the filming of the then-untitled Avengers 4. Stark appeared in leaked set photos alongside other Avengers cast members wearing a S.H.I.E.L.D. outift, which led many to believe this was a future version of Tony that had joined the global protection agency. Perhaps it was even a glimpse at Stark as the future Director of S.H.I.E.L.D., though the trailer didn't shed any light on that mystery.
Ant-Man at the "Battle of New York"
There was another reason that fans assumed the set pics featuring S.H.I.E.L.D.-suit Tony could be time-travel related. As mentioned, Tony was alongside other members of the Avengers, however, they were very clearly at the "Battle of New York" or "The Incident" which took place in The Avengers. Those set pics also featured Scott Lang in costume as Ant-Man, despite the official timeline of the MCU making it impossible for him to have been there. This has led to further time-travel rumors, including many theories involving the Quantum Realm... yet no costumed Ant-Man or past-Avengers appeared in the first trailer.
