Continuity Nod / Avengers: Endgame

"On your left."

— Falcon, repeating back to Captain America the first words Cap ever said to him (from Captain America: The Winter Soldier)

All spoilers on this page are left unmarked. You Have Been Warned!

The number of nods present in Avengers: Endgame is huge, as the Avengers travel back to several different periods shown in past MCU films. These include:

---

Films:

• Iron Man:
  • Tony's Badass Boast to Thanos just before using the Infinity Stones to destroy him once and for all is "I am Iron Man," the last line of the original Iron Man movie.
  • Pepper sends off the wreath that holds the first mini Arc reactor with the words "Proof that Tony Stark has a heart".
  • After Tony's funeral, Morgan asks Happy for a cheeseburger, much like how her father did upon returning to the United States following his captivity in Afghanistan.
  • Ho Yinsen told Tony Stark not to waste his life. His part in the Time Heist, along with his subsequent Heroic Sacrifice to save an entire universe, proves that it wasn't wasted. Stark's last moments are remarkably similar to Yinsen's, although he's surrounded by multiple loved ones and dear friends.
  • In his message to Pepper, Tony asks her not to post what he's saying onto social media, similar to how he tells a random U.S soldier in this film to not to put any pictures of him up on his MySpace account.
  • After showing the device for time travel to Cap, he says he just wants peace while doing the gesture, which references to how when the soldier who took a picture did the peace hand gesture, in which Stark responded “Yeah, I love peace."
  • In his recorded message, Tony has reverted to call Pepper “Miss Potts” something he hasn’t done since the first Iron Man film.

• The Incredible Hulk (2008):
  • When talking to Ant-Man about his transformation into his "Professor Hulk" persona, Bruce Banner notes that he saw the Hulk as a disease that needed to be cured. Most of the plot of the character's only standalone film appearance involved Bruce trying to synthesize a cure to his condition.

• Iron Man 2:
  • Once again, a member of the Avengers is dealing with alcoholism (although this time it's Thor rather than Stark).
  • The song "Make Way for Tomorrow, Today" once again makes an appearance.
  • Morgan is introduced wearing an Iron Man helmet and glove, like the kid Tony rescued from Hammer Drones at the Stark Expo.
  • The way Tony and Pepper fight off Thanos forces together is similar to when he and Rhodey fought of the Hammer Drones at the Stark Expo.
  • At the conclusion of his recorded message to Pepper, Tony whispers “it’s always you”, which he said to her upon making her CEO of Stark Industries.
  • Tony’s holographic message to Morgan is similar to the recorded message that Howard left for him back in Iron Man 2.

• Thor:
  • New Asgard is in Tønsberg, Norway, the same village where Odin led a battle against the Jotunn (aka the Frost Giants) in 965 C.E..
  • Jane Foster, whom Thor met and fell in love with in this film, is referenced for the first time since Thor: Ragnarok as an "Old Flame" of his during the discussion of the Infinity Stones.

• Captain America: The First Avenger:
  • Tønsberg (New Asgard) is also where Odin kept the Tesseract hidden in a church that was later found by Johann Schmidt in 1942.
  • 2012 Cap tells present Cap "I can do this all day". The latter is quite annoyed by it now.
  • Before going back in time, Steve tells Bucky to not do anything stupid until he gets back, to which Bucky replies, "How can I? You're taking all the stupid with you". The dialog is reversed from a scene early on in The First Avenger.
  • Cap returns to 1948 where he and Peggy have the dance they promised each other.
  • The picture of him that Peggy kept on her desk in 1970 was of him before the serum injection.
  • During the grief counseling meeting, Cap recounts how he went under the ice, awoke 70 years later, and missed his chance to be with the love of his life.
  • Cap still has the pocket watch containing a picture of Peggy from this film.
  • Professor Hulk using the rebuilt Infinity Gauntlet to undo the Snap contains some notable symmetry with the scene of Steve Rogers receiving his powers: after engaging the Gauntlet and as the energy of the Infinity Stones courses through him, Hulk is screaming in agony, and the other Avengers present try to get him to stop; however he refuses, powering through the pain with gritted teeth long enough to make the crucial snap, just as Steve did during the Project Rebirth procedure. As a bonus, when everybody is telling Hulk to stop, Steve is the one who disagrees and tells them to wait. He knows firsthand the initial pain felt through the Super Soldier project, and is seeing a similar situation play out.
  • Red Skull mocked Cap for wasting his potential on fighting for justice when he could have had the power of the gods. In this film, Cap is found worthy of wielding Mjolnir, granting him the powers of Thor, who is a god.

• The Avengers:
  • In The Avengers, Tony Stark and Bruce Banner have a conversation suggesting that the latter became the Hulk for a reason, and that the "Big Guy" was keeping Banner alive as part of a greater purpose. Here, he understands that that purpose is to use the Infinity Stones to resurrect half of the universe, noting that he was made to handle intense amounts of gamma radiation.
  • Tony once again attempts to bond with someone by sharing his blueberries (Bruce and Steve in The Avengers, Nebula in this film).
  • Tony's Apocalyptic Log for Pepper mentions his final dying thoughts will be of her; just as he intended for the last thing he saw while redirecting the warhead in The Avengers would be her face. As Tony lays dying in the aftermath of the Final Battle against Thanos, Pepper is the last person he sees as she comforts him to rest for the final time.
  • We see here what happens outside this film's plot, such as Tony telling everyone to stop posing and all of the actions taking place after the battle.
  • When Alexander Pierce inquires where Thor and Tony are going with the Tesseract and Loki, Thor responds with "Lunch and then Asgard". This references the Shawarma stinger at the end of The Avengers as well as Thor and Loki using the Tesseract to return home.
  • On their way to Vormir, Clint comments that he and Natasha are a long way from Budapest, recalling a Noodle Incident adventure mentioned in The Avengers.
  • When Thanos recognizes that Terrans who will fight him in the future are the Avengers, he calls them "unruly wretches," referencing the way the Other called them when he was reporting back to Thanos.
  • When the Avengers are mourning Natasha's death on Vormir beside the lake at the Avengers Compound, Tony quietly asks if she had any family. Steve replies that she did: them. This calls back to Steve asking Tony if Coulson had any family following his death at Loki's hands; Tony sheepishly states that he doesn't know.
  • Thor attempted to use his hammer on Captain America's shield, resulting in a massive, destructive percussive wave. Cap uses this on purpose while dual-wielding his shield and Thor's hammer while fighting Thanos.
  • Tony added a modification to his Mark 85 suit that allows it to to absorb Thor's lightning blast and redirect it back at Thanos, which calls back to this film in which Thor's lightning had actually supercharged Tony's suit.
  • The last battle sees the return of the Chitauri, the army Thanos sent to invade Earth in 2012, as well as many monsters and ships featured in unused concept art for that battle and the battle of Wakanda in the previous film.
  • Stark lists out all the people that Loki pissed off. Judging by how many have come to the final battle, it's safe to say that there is an entire universe that Thanos pissed off.
  • Tony commited a Heroic Sacrifice by taking the stones from Thanos and wearing them himself. The music used during this scene directly paralleled him sending the nuke into the Chitauri mothership.
  • Banner feared the Hulk so much that he would call him "the other guy". This time, as Professor Hulk, he tries the same therapy for Thor who can't bear hearing Thanos's name.
  • Future Tony entered Stark Tower through the broken window that Loki threw him out of in this film. He would later dive out that same window, suiting up his nanosuit in a similar way to how he did back in The Avengers.
  • In a deleted scene in Endgame, all the Avengers kneel, but not to a man like Loki.

• Iron Man 3:
  • Pepper Potts finally dons the Rescue armor during the final battle with Thanos's forces, paying off the tease where she briefly wore Tony's armor during the attack on their home.
  • A teenage Harley Keener is seen at Tony's funeral.
  • The War Machine armor Rhodey dons in the final battle has the Iron Patriot color scheme.
  • Thor ends up having a panic attack while traveling to 2013 Asgard to steal the Reality Stone, something that Tony had to deal with after the events of the first Avengers film.
  • In Tony’s last moments, Pepper tells him that he can rest now, which references to how he had been unable to rest easy since the events he had experienced in New York which carried over into Iron Man 3 and beyond.

• Thor: The Dark World:
  • When the Avengers travel back to 2012 and the aftermath of the Battle for New York is seen, a captured Loki transforms into Captain America to mock the group like he did (or rather, like he will do) in this film.
  • When told to explain the Reality Stone, Thor states it is not a stone, but an angry sludge, referencing to how Odin told Thor and Jane that it is the only relic to not appear primarily as a stone, but as a liquid mass.
  • Thor states that the team are going to need to remedy a way to extract the Aether out of Jane’s body, referencing to how none of the Asgardians were able to come up with a method to safely extract it before Malekith got hold of her in The Dark World.
  • Thor tells the Avengers of the Aether being hidden by his grandfather Bor from the Dark Elves, the same story Odin told him in The Dark World.
  • Thor mentions how Jane had absorbed the Aether and how he brought her to Asgard to find a cure, and how Jane got to meet his mother.
  • When Thor and Rocket sneak past Loki's cell in the 2013 timeline, Loki is seen lying on his bed and throwing and catching a metal cup in boredom.
  • Upon seeing the past version of his mother, Thor tells Rocket that she is to die that day, referring to how the woman was killed by Kurse in an attempt to protect Jane.
  • When Frigga asks Thor what is wrong with his right eye, he recalls the time he was hit in the face with a broadsword during the Battle of Harokin. The battle was previously mentioned in a conversation between Thor and Sif in The Dark World.
  • Frigga tells her chambermaids to send the imprisoned Loki soup and a few volumes on astronomy, which references to the conversation she had with Loki in the prison.

• Captain America: The Winter Soldier:
  • Near the beginning of the movie, Steve dons his stealth outfit from from this film when the team goes to confront Thanos.
  • The second time Steve met him, Sam Wilson was running a therapy/support group for soldiers suffering from PTSD. After the Time Skip, Steve himself now runs a therapy/support group for citizens suffering from Snapture-induced PTSD.
  • Present Cap runs into the S.T.R.I.K.E. team (complete with Rumlow and Rollins) and Sitwell in an elevator. However, unlike the first meeting, he doesn't fight his way out with the scepter, he defuses it with a whisper of "Hail Hydra".
  • The way Cap leans close enough to whisper “Hail Hydra” to Sitwell is just like how Senator Stern did (or would do).
  • Alexander Pierce also returns in this movie, encountering the 2012 Avengers and demanding that they turn over the Tesseract, the Scepter, and Loki to the authorities due to the former two being S.H.I.E.L.D property for over 20 years, and the latter having to answer for his crimes.
  • 2012 Cap puts present Cap in a chokehold similar to how Cap defeats Bucky.
  • Present Cap wins by telling his 2012 version that Bucky is alive (which causes the latter to enter a Heroic BSoD) and brainwashing him with the scepter.
  • While Cap and Tony are in S.H.I.E.L.D.'s 1970 headquarters, Howard Stark comes down to the bowels of the installation looking for Arnim Zola and finds Tony instead. As revealed in this film, Zola had been granted amnesty and was "collaborating" with S.H.I.E.L.D. (read: working for HYDRA to infiltrate S.H.I.E.L.D.) at the time.
  • Speaking of Zola, a very small digital recreation of his face can briefly be seen in the back of the room where the Tesseract is located, alluding to Zola's eventual gambit to create a digital copy of his consciousness to continue serving HYDRA for decades after his death.
  • As Captain America is facing down Thanos's entire army, seemingly alone, the first voice we hear from any of the un-snapped heroes is Sam Wilson on his comms with the same Running Gag from The Winter Soldier: "On your left."
  • "It's Been a Long, Long Time," the song featured in the film's final scene, first appeared in the MCU when Nick Fury was hiding out in Cap's apartment in Winter Soldier.

• Guardians of the Galaxy (2014):
  • The Sakaarans (Ronan's goons) and their necrocraft take part in the final battle. Ronan himself is name dropped by Thanos while talking to Nebula and Gamora.
  • Howard the Duck is seen for a split second among the heroes coming out of the portals.
  • Past Thanos's characterization reflects his more overt villainy as portrayed in this film (in which he casually threatens to "bathe the starways in [Ronan's] blood") rather than the more universe-weary Thanos seen in Infinity War and Endgame's opening.
  • Rocket says the exact same words in reaction to Carol's destruction of Sanctuary II as he does to getting a gun from Drax on the Kyln.
    Rocket: Oh, yeah!
  • If you look closely at Kraglin, you can see that he's wearing a fin similar to the one Yondu wore in this film.
  • Upon arriving on Morag, Romanoff kicks an orloni, something Quill did in the first Guardians of the Galaxy.
  • Rocket mentions how Quill found the Power Stone on Morag. Upon arriving in 2014, Rhodey and Nebula intercept him while he is listening and dancing to his Walkman music.
  • Nebula had previously alluded to her hatred of the Black Order (her adopted siblings) in this film, considering them far worse than Gamora ever was. Here, we see Nebula's words were far from unwarranted, as Ebony Maw doesn't hesitate to telekinetically strangle her upon the slightest implication of her betraying Thanos, and seems openly gleeful in doing so.
  • Tony’s heroic sacrifice is a little reminiscent of Groot’s, with them both using a first person pronoun, then a form of the verb “to be”, and then their name, right before they die protecting everyone they know and love.

• Avengers: Age of Ultron:
  • We find out how HYDRA gets the scepter — which is in Strucker's possession at this film's opening.
  • When Tony reunites with the Avengers, he recalls his idea from this film of building "a suit of armor around the world" to protect Earth against alien attacks. He also recalls Steve's words that if they would lose, they would do so together, from the same movie.
  • Cap summoning Mjölnir pays off the montage of characters attempting to move the hammer in Age of Ultron, where Cap was able to make the hammer budge before giving up. Thor's elation at seeing Cap wield the hammer recalls the fact that he clearly noticed Cap's near-success in Ultron.
  • Clint Barton's homestead, and family, show up again in this film.
  • At the end of Age of Ultron Tony comments, "Maybe I should take a page out of Barton's book. Build Pepper a farm, hope nobody blows it up." After the five year Time Skip, he has indeed settled down with Pepper and started a family, only they live in a remote woodland location instead of a farming land.
  • Captain Rogers chides Stark for shouting "Shit!" during battle like a sweet old schoolteacher in the opening of Age of Ultron; 8 years later, the former now uses said curse-word freely in exasperation, whereas the latter has to teach his adorable little girl not to say "shit" like a sweet old schoolteacher.
  • While Thor is talking to his mother, he drinks from the same alcohol bottle he had in this film.
  • Bruce is the most upset by Natasha's death, and is actually shown losing his composure twice while grieving for her — rare moments where the Hulk half of his psyche seems to briefly regain control.
  • Cap gives the "Avengers Assemble" war cry, which was cut off by the end credits in Age Of Ultron.
  • When Thor is asked who he thinks helped get Banner through a rough patch, he drunkenly responds Natasha, referring to Banner and Natasha’s brief relationship in Age of Ultron.
  • During the final battle, Captain America's vibranium shield is broken in half by Thanos. This is exactly what happened in Tony's vision. Also, Black Widow’s death in that vision comes to pass in this film, and with her body in the same position.
  • Another vision that came true is that Captain America ends up getting that dance with Peggy Carter. The difference is that he's content to live his life without a war to fight at that point.
  • A trio of characters fire a constant beam of energy at an enemy to disable at the villain. In Age of Ultron it is Tony firing hand blasters, Vision his Mind Stone beam, and Thor lightning from Mjölnir at Ultron Prime to injure him. Here, Pepper Potts fires her beams, Shuri her gauntlets, and the Wasp her blasters at Thanos to disable him while Danvers approaches the van.

• Ant-Man:
  • Hank Pym seems to have gotten over his hatred of the Stark family as he was at Tony's funeral.
  • During the climax of this movie, Scott uses his blinker to find his old van that he's driven since this film, which sounds its iconic La Cucaracha horn.
  • Scott tells Hank his days of "breaking into places and stealing shit are done" in Ant-Man. It's played with here, but he did it again — only he and the Avengers broke into other timelines and stole some stones (and Mjölnir) and returning them in an attempt to repair damage done.
  • Once again, Scott surfs on something in shrunken form, albeit with debris from the Avengers base rather than ants from this movie.
  • Hank Pym is shown working for S.H.I.E.L.D in 1970, and the Pym Particles make a physical re-appearance, looking exactly like the knockoff that S.H.I.E.L.D made (or will make) in 1989.
  • Kurt complains to Paxton that a black guy threw him into the "disgusting" van in the climax. Cap's first words after hearing the horn?
    Cap: Anyone see an ugly brown van out there?
  • In order to transport the Benatar through their Quantum Tunnel, the Avengers opt to shrink it down to a keychain/toy model size that can fit in the palm of Clint's hand, similar to what Hank did with the tank from this film.
  • Scott calls his plan to travel through time to get the Stones a Time Heist. In his first film, Scott was chosen by Hank to pull off a heist.
  • When Cap breaks into Hank Pym's lab to steal the Pym Particles, the heist music from Ant-Man is played.
  • The mambo drum rattle used to kick off Luis' stories can be heard during pivotal moments of the Time Heist, like Scott breaking into past Tony's arc reactor.

• Captain America: Civil War:
  • After originally demanding at the end of their climactic battle that Steve give up his shield because his father made it (and used it to protect Bucky, who technically killed him), Tony decides to give it back, stating that it was because "He made it for you."
  • Ant-Man is holding some orange slices when Hawkeye returns from his time travel test run.
  • Once again, Ant-Man breaks into Tony Stark's machinery to disable it. Only this time it's not the Iron Man armor, it's past Tony's arc reactor — and present Tony's the one asking him to do it!
  • Rhodey busts Scott's chops a bit by scaring him and then sarcastically calling him "Regular-Sized Man". He clearly hasn't forgotten the way Scott kicked him around as Giant Man during the airport fight scene in Civil War.
  • Black Panther makes it a point to call Clint by name before asking to take the Gauntlet. This refers to when Clint tried to formally introduce himself during their battle in Civil War, and T'Challa coldly remarked "I don't care."
  • During the climactic battle between the two armies of heroes and villains, Steve refers to Spider-Man as "Queens," referring to the conversation they had about their mutual New York roots in Civil War.
  • Tony touches Rhodey's arc reactor to have F.R.I.D.A.Y. read his vitals in Civil War. Pepper does the same with her armor - also connected to F.R.I.D.A.Y. to have her read Tony's vitals.
  • During his crazed speech, Tony calls Cap a liar, referencing to how the latter lied about knowing who killed his parents.

• Doctor Strange:
  • When Doctor Strange signals to Tony that they are indeed in the one timeline where they defeat Thanos, his hand is still trembling.
  • Ancient One is shown pushing Banner’s astral form from his body before he tries to take the Time Stone from her, the same method she used on Strange when he got angry with her for seemingly being a fraud.
  • When Professor Hulk goes to the New York Sanctum to get the Time Stone and says he's looking for Stephen Strange, the Ancient One says he's about five years too early and Strange is busy performing surgery at a hospital; she mentioned in Doctor Strange she had peered through time to learn about Strange. However, she's surprised when Hulk mentions Strange gives up the Time Stone to Thanos willingly, which fits with her mention in Doctor Strange that one cannot look ahead past the point of their own death.
  • In his film, Strange did his studying using his Astral form while his body slept. Bruce was using his astral form to talk to the Ancient One while Hulk's body slept in a corner. Unlike the former, the latter wasn't in this form by choice.

• Guardians of the Galaxy Vol. 2:
  • Quill's Zune that he received at the end of this movie can be heard playing "Dear Mr. Fantasy" by Traffic during the opening logo, and while Tony and Nebula are playing paper football.
  • Nebula is taken aback after winning against Tony in their paper football game, referencing back to Nebula's reveal in Vol 2 that she never won once in any of her matches with Gamora.
  • Contraxia, the planet where the Ravagers gathered at the beginning of the movie, is visible in the portal that they emerge from during the Battle of Earth.
  • We found out why Drax never wore shirts in this movie. He's certainly holding his own well during Tony's funeral wearing the A-Frame shirt.
  • Drax is seen rapidly (and gleefully) stabbing Cull Obsidian in the back (to distract him from killing Korg) like he was trying to cut through the Abilisk in the opening scene — from the inside.
  • Quill and Thor try to one-up each other with the latter telling the former he's "assisting" when he touches the map only for Quill to move it back - multiple times. This film has Rocket and Quill constantly stealing control of the Milano while escaping the Sovereign - a pissing contest that leads to the ship's demise.
  • When the Avengers head to space to find Thanos at the Garden, Rocket requests that the people who haven't been to space to not throw up on the Benatar, referencing how Baby Groot vomited after making too many hyperspace jumps in this movie.
  • While going over the details of the Power Stone, Rocket mockingly calls Scott Lang a puppy, just like Mantis did when asking Drax if she could pet him.
  • Once again, a big funeral is held for an important character who served as a flawed, but loving father figure to a character named Peter in the franchise. Unlike Yondu however, Tony Stark touched many more people just the Ravagers and the Guardians of the Galaxy.

• Spider-Man: Homecoming:
  • In this film, one of the Running Gags of the film was the suit's AI Karen suggesting to Peter that he use the "Instant Kill" mode. In Endgame, he finally does activate it against the Outriders.
  • Homecoming featured Tony rejecting a hug from Peter, telling him "we're not there yet." As soon as Tony sees Peter resurrected in Endgame, though, he gives him a big hug.
  • Aunt May Parker attends Stark's funeral.

• Thor: Ragnarok:
  • In the prologue, Thor's casual clothing is similar to the outfit he wore during his search for Odin on Earth with Loki.
  • Before he dies on a cliff in Norway, Odin tells his sons to "remember this place" and calls it "home." In the end, New Asgard really is located in Norway, specifically in Tønsberg, which is a small village by the sea.
  • Hulk/Banner still calls Valkyrie "Angry Girl", and we still haven't gotten her name.
  • Frigga asking Thor what is wrong with his right eye is also a reference to the eye he lost in this film, and had subsequently replaced with an artificial one in Avengers: Infinity War.
  • Thor insists that he'd be the one to use the Gauntlet to reverse the snap because he was the "strongest Avenger" though everyone else disagreed. The gauntlet was actually used by who the Quinjet referred to as the strongest Avenger in Ragnarok, Hulk.
  • Thor refers to Valkyrie as "Your Majesty" after passing the reins of New Asgard to her, like he was called by her in her Scrapper 142 persona.
  • Thanos spins his double-blade at such an accelerated speed that it is able to completely deflect a concentrated beam from Iron Man imbued with Thor's lightning. Thor utilized the same tactic of spinning Mjölnir at a similarly ridiculous speed in order to block Surtur's sword flames.
  • During his drunken speech explaining the Aether, Thor sadly mentions how and Jane were not dating anymore, something that was addressed in Thor: Ragnarok.
  • Upon arriving at New Asgard, Rocket says it is a step down from a glorious palace, to which Hulk responds by telling him to show some respect since the Asgardians are lucky to have a home after losing their land, referencing to how Asgard was destroyed in Ragnarok by Surtur and Hela.

• Black Panther:
  • Shuri has both of her gauntlets back; she had lost one to Killmonger in this film, which never returned in Infinity War. She may have had a spare in her lab that she acquired.
  • During the sprint to the van with the Stark Gauntlet, we see T'Challa use the Shockwave Stomp ability he acquired from Shuri's upgraded suit as well.

• Avengers: Infinity War:
  • In his Apocalyptic Log to Pepper, Tony recalls that he promised Pepper "no more surprises", which he did at the beginning of Infinity War.
  • In his first scene, Steve is seen just wrapping up shaving his beard that he grew to cover his identity in this film.
  • Tony brings up several moments from his experience on Titan: Thanos throwing a moon at him, Doctor Strange giving up the Time Stone, and losing Peter Parker.
  • When the team find Thanos and learns he had the stones destroyed, an enraged Thor decapitates him taking Thanos' advice from Infinity War by going for the head. Bonus for when a shocked Rocket ask what he just did, Thor replies "I went for the head."
  • As Thor walks out of Thanos’ hut, the same ending music of Infinity War is played.
  • Tony's daughter is named Morgan, just like the son in his dream as disclosed to Pepper in Infinity War.
  • Tony's dreaming of having a son mirrors 1970 Howard mentioning his hope to have a daughter. What actually transpires is opposite as well.
  • Professor Hulk is eating Ben & Jerry's "Hunka Hulka Burning Fudge" during the "Time Heist" brainstorming session, which Wong mentioned in Infinity War.
  • Right before being decapitated by Thor, Thanos has a brief moment with Nebula, which he considers that he had treated too harshly, which we saw back in Infinity War.
  • The Asgardian soldiers call Rocket a "rabbit," just like Thor keeps calling him throughout Infinity War.
  • Thanos and Ebony Maw use the same machine that held Nebula captive in this film to peer through the memories of 2023 Nebula that 2014 Nebula is synching up with.
  • In Infinity War Thor made the big entrance to change the course of the battle - wiping out outriders and their ships with Stormbreaker; here, Danvers flights directly through the Sanctuary II to turn the tide of the battle.
  • The Vormir scene, with the exception of the actions after the Red Skull lays down the deal but before Natasha falls, mirrors the scene in the movie. Even the music is nearly identical.
  • Nebula is the one to inform the team about the location of the Soul Stone and Gamora's death at the hands of Thanos, something she had learned in Infinity War.
  • Nebula mentions "the tree" (Groot) as the other option to 2014 Gamora after she subdues Quill. Thor (who used the name again at the end of Endgame) and Eitri both called Groot Tree in Infinity War.
  • Hawkeye is shown awakening in a pool of water with the Soul Stone in hand after Natasha’s sacrifice, exactly how Thanos received the Stone in this film.
  • The reunion of the Guardians showed Drax eating something, which was was much less crunchy, suggesting that he probably was invisible until he spoke up, unlike his attempt at it in Infinity War.
  • At one point during the climactic battle, 2014 Thanos has Thor subdued pressing Stormbreaker into him much like how Thor pressed Stormbreaker into Thanos in the Battle of Wakanda moments before the snap.
  • T'Challa led his army with the "YIBAMBE!" warcry again.
  • During the final battle, Iron Man asks Doctor Strange if this is this the one outcome they defeat Thanos out of the million possible outcomes Strange saw back in Infinity War.
  • When Captain Marvel battles Thanos, she holds his fingers apart to prevent him from snapping his fingers, just like Captain America did in this film. She's much more successful than Steve, though.
  • Upon seeing Tony dying, Peter says sorry, which he said himself in Infinity War before turning to dust.
  • The Female Avengers providing backup for Captain Marvel, with Okoye even saying “She’s got help” could be considered a subtle reference to how Black Widow and Okoye helped Wanda fight Proxima Midnight in Infinity War.
  • At the end of both this film and the first one, Thanos sits down, overlooks the area and gives a final expression. In Infinity War, after he snapped half the universe out of existence, he retreated to an uninhabited, beautiful looking planet and he smiled up at a quiet sunrise. In Endgame, it is the complete opposite: once Tony snaps Thanos and his army out of existence, he is in the dark, obliterated remains of the Avengers' base, and hangs his head down to the ground with an expression of defeat and agonized sorrow just before he's dusted.

• Ant-Man and the Wasp:
  • When Clint is teaching his daughter archery, a tracking device can be seen on his ankle; the very same device that Scott wore when he was under house arrest for violating the Sokovia Accords, just like Clint.
  • The Quantum Realm is discussed by Scott and the surviving Avengers as a way of traveling back through time, something that was mentioned by Janet van Dyne in the post-credits scene of this movie. There's also a large version of it built in the Avengers base, albeit made for the purpose of sending people through it rather than a vehicle with people in it.
  • Scott mentions how Hope was supposed to bring him out of the Quantum Realm in this movie, which didn't happen because of being dusted here.
  • Scott and Hope reuniting with Cassie at the end of the film is similar to how their last scene together was in this film.
  • After mocking Scott for calling Steve "Cap" at one point during this film, Hope does the same thing herself during the final battle in front of Scott. The two share a grin, acknowledging the point.
  • Scott's van still retains the X-Cons logo, as well as the mini-Quantum Tunnel that was installed into it during the post-credits scene of this movie.
  • When 2014 Nebula uses the Quantum Tunnel to bring the Sanctuary II to the present day, it's shown rapidly growing to proper size in the same way Hank Pym's vehicle did while returning from the Quantum Realm in this movie.
  • The suits that the Avengers wear to travel through the Quantum Realm look similar to the suit Hank wore to rescue Janet in.
  • This film wasn’t the first time that Scott Lang ended up in the body of a child due to issues involving Pym tech.

• Captain Marvel:
  • Carol is visibly upset as a result of finding out that Nick Fury had been dusted.
  • Just like in her origin film, Captain Marvel destroys a huge starship by the simple expedient of using her Space Stone-granted durability to fly through it several times.
  • When asked where she has been all these years, Carol answers that there were a lot of planets who didn’t have people like the Avengers to protect them; she implies that she wasn't always successful in bringing salvation to those who needed it in their darkest hours, showing that she doesn't see nor consider herself superior to the Avengers the way War Machine erroneously assumed she does. This references to how she intended to help the Skrulls in her film find a new home.
  • Following the five year skip, Captain Marvel is sporting a shorter hairstyle that is reminiscent of Mar-Vell in her solo film.

TV Series

• Agent Carter:
  • Natasha's braided hair is reminiscent of 1940's Red Room graduate Dottie Underwood's during her childhood.
