Easter Eggs You Probably Missed in 'Avengers: Endgame'
Like its Marvel Cinematic Universe brethren, Avengers: Endgame is chock-full of references to past MCU films and the comic books. Not only did we go back in time to revisit Thor: The Dark World (who'd have guessed that would be the Thor movie we'd see again?), but long-promised thrill moments, like Cap wielding Mjolnir finally showed up.
There are also plenty of jokes, references, and other easter eggs hidden in smaller moments throughout Endgame, and Marvel fans will be curious about just how many they caught and how many they missed. This list will be updated upon rewatch after rewatch, but for now here's a list of the most prominent easter eggs in Avengers: Endgame -- presented in chronological order... which means real movie time, not quantum time.
Iron Man's callbacksIn Tony Stark's opening monologue to his helmet in space, he includes two references to previous Iron Man movies: "Don't post this on social media," which is a Stark line from Iron Man, and, "It's always you," which is what Tony said to Pepper when handing over Stark Industries in Iron Man 2.
Captain America's therapyAfter the time jump, Captain America is working for a therapy group, just like Sam/The Falcon was when we met him in Winter Soldier.
A Russo brother cameoDirector Joe Russo shows up as a gay man in Captain America's support group.
Ken Jeong's bookWhen Scott Lang re-materializes in San Francisco, Ken Jeong (from Community and the Hangover movies) appears as a security guard, sporting a fake mustache. Not only that, but he's reading a collection of JG Ballard short stories called Terminal Beach, which includes the short-story "End-game."
Black Widow's ballet pastBy Natasha's desk in Avengers headquarters, she keeps some worn ballet shoes, a reference to the ballet school cover she used for her assassin training in Age of Ultron.
Namor the Sub-MarinerThe underwater earthquakes off the coast of Africa referenced by Okoye in the holo-conference could be our first indication Namor the Sub-Mariner, a character whose rights are currently at Universal, is in-universe. Namor rules over Atlantis, the underwater city, and the Atlantians have found themselves at odds with Wakanda and their Black Panther several times in Marvel Comics history.
Thanos' armorEndgame takes an image directly out of the Infinity Gauntlet comic series when it depicts Thanos' armor being used as a scarecrow.
Stones destroying StonesThanos destroyed the Infinity Stones with the Infinity Stones, which has only happened once in Marvel comics. When Captain America used the Gauntlet to stop an incursion of worlds during the Jonathan Hickman-written Infinity crossover event, the stones ceased to exist (until the entire comic book universe was relaunched with Secret Wars, and along with the relaunch, new Infinity Stones were introduced).
Iron Man's daughterTony Stark's daughter, Morgan, could be related to Morgan Stark, the comic book character who's Tony's eccentric and almost evil cousin. There seems to be no MCU origin behind her name.
Tonsberg, NorwayNew Asgard is in Tonsberg, the Norwegian city where Red Skull acquires the Tesseract in the beginning of Captain America: The First Avenger. Seems like Asgardians have had roots there for some time.
Fortnite crossoverWhen Rocket and Hulk go to collect Thor, Korg is playing Fortnite using the Brite Bomber skin. The online Battle Royale-style game, where you can play looking like multiple characters (by using "skins," or different outfits) has partnered with Marvel to bring limited-time game modes to Fortnite for the Infinity War and Endgame releases.
Hawkeye's alter egoBlack Widow finds a murderous Clint Barton in his Ronin persona. Though he's never called that in the film, the Hawkeye-goes-rogue storyline and the costume in the film are both nods to the character's time as Ronin in the comics. The person Ronin kills on screen is a character named Akihiko, played by Hiroyuki Sanada. In the comics, Akihiko runs a group called the Shogun Reapers, who are kind of like a tech-forward Yakuza.
Pym ParticlesScott says they have limited Pym Particles because Hank Pym was dusted, which happened in the post-credits scene of Ant-Man and the Wasp.
MjolnirCaptain America has been able to wield Mjolnir a few times in the Marvel Comics, going back to the first time in 1988's The Mighty Thor #390, but it wasn't until 2011's Fear Itself crossover event that Cap held it, yelled, "Avengers assemble," then used lightning powers, so let's peg Endgame's usage to that.
Captain America's shieldCaptain America getting his shield broken by Thanos also happens in 1991's Infinity Gauntlet comic series, though that time Thanos was able to punch it into pieces instead of hacking away at it with a double-edged sword like he does in the film.
When Tony brings Captain America's shield back to him, Tony says, "He made it for you," referring to the Dominic Cooper version of Howard Stark from Captain America: The First Avenger. Tony has kept the shield since Cap abandoned it in Captain America: Civil War.
