----
!!!''Film/AvengersEndgame'' provides examples of the following tropes:
[[foldercontrol]]
[[folder:#]]
* EleventhHourRanger:
** Captain Marvel. After being absent from Earth's events throughout the MCU timeline, she returns to assist the other survivors of Thanos's culling of half of all life in the universe. Then she leaves again when Natasha dispatches several Avengers on missions in space, only to show back up for the final battle.
** Hawkeye is the last to join the group, having been absent from ''Avengers: Infinity War'' due to his house arrest after ''Captain America: Civil War'' and taking up vigilantism as Ronin after the time skip.
** Ant-Man, Rocket, Nebula, and Captain Marvel are now officially members of the Avengers.
** Pretty much everyone resurrected from the first film in the climatic battle.
** The Wasp and Pepper Potts (in her own suit of Iron Man armor) also join the battle.
** In a blink-and-you'll-miss-it moment, you may well spot Howard the Duck brandishing a gun with the Ravagers as they head into battle.
* TwentyMinutesIntoTheFuture: The bulk of the movie takes place five years after ''Infinity War'', which was set in 2018, so therefore set in 2023.
* TheSeventies: Steve and Tony travel to 1970 to get the Tesseract after the previous attempt in 2012 failed spectacularly. The opening scene shows a carful of hippies (among them [[CreatorCameo Stan Lee]]) driving by the entrance of Camp Lehigh and jeering, and later, Howard asks if Tony is a beatnik, due to his facial hair.
[[/folder]]
[[folder:A]]
* AbdicateTheThrone: Thor declares Valkyrie the ruler of New Asgard, after commenting that for the first time in a thousand years, he won't have to be who he's supposed to be, while acknowledging that Valkyrie was essentially ruling New Asgard already while he spent the last five years doing nothing but drinking, eating junk food, and playing video games.
* AbortedArc: The Sokovia Accords are totally unmentioned throughout the movie, but Captain America and Black Widow are no longer considered enemies to the public, Rhodey's court martial seems to have never happened, and Hulk is able to operate in public to the point where ''he's able to pose for selfies with kids''. Presumably, the issue has more or less been dropped in the wake of the larger issues that the Earth is facing, or otherwise rewritten in the five year gap.
* AbsenteeActor:
** Emily [=VanCamp's=] Sharon Carter is nowhere to be seen at Tony Stark's funeral after the snap is undone, nor is she mentioned.
** Martin Freeman's Everett Ross, previously seen in 2018's ''Black Panther'', is also absent.
** Lupita Nyong'o (Nakia) did not appear in the film.
* AbsurdlySharpBlade:
** Stormbreaker, which not only decapitates a weakened post-snap Thanos with a single strike, but later in the climax starts to cleanly dig into Thor's armor when Past Thanos is pushing it into his chest, while Thor is also trying to push it away.
** Thanos's double-bladed sword, which is sharp enough to take chunks off of Cap's famously "unbreakable" vibranium shield.
** Clint's sword is not as impressive as the other two, but it is nonetheless shown to be able to slice an Outrider in two.
** Valkyrie's lance is capable of slicing into a Leviathan's armor plating like a hot knife through butter. This is the armor that Jarvis once said "we will lose power before we break through that shell."
* AchillesInHisTent: Of all the Avengers, Thor takes the events of the Snap the hardest. Five years later, he's become an [[FormerlyFit overweight]], [[DrowningMySorrows alcoholic]] [[{{Hikikomori}} shut-in]] who spends his days drinking beer and hanging out with Korg and Miek as they play ''VideoGame/{{Fortnite}}''. Rocket and Hulk coax him into coming out of retirement, but he doesn't start to get his groove back until after getting a pep-talk from his mother while time-traveling to Asgard in 2013.
* AdaptationExpansion: The movie actually shows the fallout of Thanos's victory following the Snap. In the ''Infinity Gauntlet'' storyline, the Snap occurred within the first few pages and the counterassault (and subsequent ResetButton) came within 24 hours, too short a time-frame to display any real consequences that such an event would have on the population.
* AdaptationalVillainy: In the comics, after the events of ''ComicBook/TheInfinityGauntlet'', Thanos comes to realize he's not worthy of wielding the god-like powers of the Infinity Gems, so he eventually becomes an AntiVillain who often fights on the side of the heroes. Here, there is no such HeelFaceTurn: the older version of Thanos remains convinced his actions were justified, while the 2014 version is even more omnicidal than in the previous films.
* AdultFear:
** Clint gets to live his worst nightmare when, in the middle of a lighthearted picnic, he only turns his head a moment and sees his family has disappeared without warning. He is then overwhelmed by the confusion and distress of having lost his wife and children without having been able to protect them, or even knowing what happened.
** Scott Lang gets a moment of anguish when he worriedly looks at the memorials to the fallen in the hopes his daughter Cassie is not among the victims. She's not, but he gets another variation of this trope on seeing '''his''' name: his daughter thinks he's been dead for five years, and he's missed five years of her childhood.
** PlayedForLaughs when Tony realizes his daughter heard him swearing and is up late past her bedtime. The idea that your kid can start repeating curse words and you have to explain yourself or bribe her with popsicles.
* AdvertisedExtra:
** Captain Marvel was heavily featured in the promotional material for the film, especially after [[Film/CaptainMarvel2019 her own movie]] proved to be a huge hit at the box office. Despite this, she disappears after the fight with Thanos in the first act, and is absent from the film until the final battle. This is pretty much a repeat of what happened with Black Panther in the marketing for ''Infinity War'', right down to the ads overselling the size of his role due to the success of his solo movie. {{Justified|Trope}} due to her [[StoryBreakerPower abilities matching if not exceeding those of Thanos]] (without the help of a stone); and when she ''does'' appear in the final battle, she proves to be a difference-maker, destroying Thanos' ship and outclassing the Mad Titan himself. She also had other planets to mind that didn't have heroes of their own.
** Okoye is also featured prominently in the American theatrical poster, as is Valkyrie in some of the international ones. Like Captain Marvel, they don't get to do much until the final fight with Thanos's forces.
** Wong is shown in one of the "Avenge the Fallen" posters in color but much like Captain Marvel, Okoye, and Valkyrie, doesn't appear until the Avengers really need them.
* AnAesop:
** Thor learns that the measure of a true hero isn't living up to the expectations of others, but by doing your best being a decent person that is true to yourself.
** Also, after [[MyGreatestFailure loss]] comes [[MyGreatestSecondChance second chances]]: whether it be a chance to take back what you lost, or build something new out of what you have left. Ultimately, the Avengers realize this and use this to their advantage (such as when Steve and Tony, after losing their chance to gain the Tesseract, stay determined and resourceful and find another way) which ultimately ensures their victory; while Thanos, who is given a second chance to achieve a permanent victory in his world (by learning from the Avengers' actions and doubling-down on his plan to erase 100% of the universe rather than just 50%), instead goes for the much more brash and careless option and ultimately ensures his own demise.
** Being a hero requires being willing to make [[HeroicSacrifice the ultimate sacrifice]]. The Avengers spend most of ''Infinity War'' trying to find a way to extract the mind stone from Vision without killing him because to quote Steve, "they don't trade lives". They run out of time and ultimately Wanda has to do what they've been putting off the whole movie. However Thanos is able to use the time stone to rewind his destruction and complete the gauntlet, leading to the snap. This time around no one hestitates to lay down a life to stop Thanos. Clint and Natasha are both willing to throw themselves off the cliff to get the soul stone, Bruce wears the gauntlet to snap everyone back despite not knowing exactly what it will do to him, and then Tony also uses the guantlet knowing it will kill him.
* AffirmativeActionLegacy: Just like his comics counterpart, Steve retires and passes the shield to Sam Wilson.
* AfterTheEnd: The story shows how the world has been dealing with the loss of half of all life in the universe in the [[TimeSkip five years]] since the prior movie, which [[DarkestHour isn't great]] despite what Thanos may think. People are traumatized, cities are quiet and empty-feeling, and no one can really bring themselves to move on or even do anything. Steve has actually started a support group for people in order to try and get them to move on with life and continue.
* AlasPoorVillain:
** The prime Thanos, while he succeeded in wiping out half the universe, believed he was doing it for a very noble cause. So it is still sad to see him overpowered by the Avengers and killed by Thor. The former after being severely injured by using the stones to destroy the stones and the latter after he tells Nebula that he's beginning to think he treated her too harshly.
** Once Thanos and his forces are now on the receiving end of the snap, you can just see it in his eyes that he knows that he's doomed. He rests in the desolate Avengers HQ, looking up with an expression of pure agony as he slowly lowers his head; eyes closing, and body sulking down to the ground. No [[VillainousBreakdown mental breakdown]]. No [[FamousLastWords last words]]. No [[SkywardScream screaming]]. No [[HeelRealization admission of wrongdoing]]. Not even an [[BigNo expression]] [[ThisCannotBe of]] [[LittleNo disbelief]]. Just utter silence, despair and surrender as he awaits the [[ArcWords inevitable]].
** As they turn to dust, Ebony Maw reaches out to Thanos in confusion and terror, and Proxima cradles the dead Corvus as she dies (he was ran through by Okoye earlier).
* AlienArtsAreAppreciated: Korg and Miek are playing ''VideoGame/{{Fortnite}}'' when Rocket and Professor Hulk find them and Thor in New Asgard.
* AlienInvasion:
** The Chitauri invasion of New York City during ''The Avengers'' is revisited, although most of the action takes place after the invasion has been dealt with.
** 2014 Thanos makes his way to the Earth of the prime timeline, along with his whole army. Only this time the Avengers and their allies are all able to gather at the same place for a welcome committee.
* AllDeathsFinal: At least in the case of the Soul Stone and who is sacrificed to retrieve it. They can't be brought back to life, even with all six Stones. Likewise, a being who uses all six Stones but isn't strong enough will also die and can't be brought back. It's also implied that only the people directly killed by the Snap were brought back and not, say, the people killed when millions of cars on the road suddenly lost their drivers, or anyone who was killed during Thanos's quest for the Stones.
* AllForNothing: By the end of the first act, the Avengers find and kill Thanos, but even ''before'' Thor decapitates him, they realize it's all for naught since Thanos already destroyed the Infinity Stones beforehand, robbing them of a means to undo the damage he has done, and reducing them to just trying to pick up the pieces, at least until Scott shows up with an idea.
* AllThereInTheManual:
** The Russo brothers answered a few hanging questions the movie made in a [[https://bgr.com/2019/04/30/avengers-endgame-ending-russo-brothers-on-captain-america-iron-man/ BGR article]]. One of the biggest {{Plot Hole}}s was just how did Past-Thanos bring his entire ship and army into the future? There's literally no questioning of how it happened. The banging sound in the Marvel logo at the end of the credits was the Russo's way of saying goodbye to Iron Man.
--->'''Q:''' How did Thanos bring his army to the future?\\
'''A:''' There is a guy called Maw in his army, he was [[AWizardDidIt a great wizard]]. Thanos himself was a brilliant genius as well. Those two easily reverse-engineered and mass-produced Pym Particles.
** The ages of Scott Lang's age-altered selves are given in the credits as 12, 93, and [[TheLastOfTheseIsNotLikeTheOthers baby]].
** Thanos's double-bladed sword is described as made of uru metal, like Mjölnir and Stormbreaker, explaining why it can cleave Cap's shield.
* AllYourBaseAreBelongToUs: The finale begins when Thanos from 2014 arrives at the Avengers Headquarters and the resulting battle utterly obliterates and destroys the compound.
* AlmostOutOfOxygen: Tony Stark and Nebula have run out of food and water and are about to run out of oxygen on their way back to Earth on the ''Benatar'', the Guardians' space ship. [[BigDamnHeroes Cue]] [[Film/CaptainMarvel2019 Carol Danvers]].
* AlternatePersonalityPunishment: In the aftermath of Thanos ending half of all life in existence, the heroes manage to assemble what's left of the team and beat the crap out of Thanos... who has taken up the CallToAgriculture and barely puts up any resistance. He doesn't even have the Infinity Stones anymore, having used their own power to destroy them, greatly weakening himself in the process. The Avengers kill him anyway, but it's obvious they feel no satisfaction or justice from doing so. Fortunately, they go back in time to retrieve the stones to undo the damage and are followed by pre-snap Thanos, resulting in a Thanos who is very much satisfying to kill, even if he technically hadn't killed half of all life (it helps that having seen the results of only killing half of it, he decides to kill the ''entire'' Universe and start over so no one will remember his role).
* AlternateSelf: When travelling in time, some Avengers meet past versions of themselves. The "alternate" part is in full motion when each of these timelines is changed by them.
* AlternateTimeline:
** Changing any event in the past creates one of these, while the traveler's own past remains untouched. As such, the six timelines that the Avengers create include:
*** '''1948''': (3 years after ''Film/CaptainAmericaTheFirstAvenger'') The main timeline version of Steve goes here to spend his life with another timeline's Peggy Carter after World War II, before returning to his original timeline after her (presumed) death in 2016. As such, Steve is an old man when he returns. This one is a weird one because the writers and directors disagree on whether this was ''actually'' an alternate timeline, or whether it was part of the original timeline all along, with Steve actually [[CanonCharacterAllAlong being Peggy's mystery husband who was discussed in]] ''Film/CaptainAmericaTheWinterSoldier''. As the year Steve travels back to is 1948 and not 1945, this would still give the ''Series/AgentCarter'' series plenty of time to take place.
*** '''1970''': After Hank Pym is distracted by a fake emergency call, four vials of the Pym particle go missing from his lab at the Camp Lehigh S.H.I.E.L.D. facility (granted they're only taken and used by Steve and Tony to get back to the present, but Hank and S.H.I.E.L.D. have no way of knowing this). Howard Stark also has a conversation with one "Howard Potts" (his future son Tony from the main timeline), and Captain America sees photographs on the desk inside the office of S.H.I.E.L.D.'s director Peggy Carter that make it clear she never forgot him.
*** '''2012''': (right after the climax of ''Film/{{The Avengers|2012}}'') Loki escapes custody with the Tesseract immediately after the Battle of New York and is never imprisoned on Asgard, and HYDRA agents believe Captain America is on their side (but 2012 Steve is unaware of this). The Ancient One learns of Doctor Strange's plan to stop Thanos years later, and Captain America is also made aware of Bucky's survival (although how much he believe this information is up for debate).
*** '''2013''': (during ''Film/ThorTheDarkWorld'') The Asgardian army chases a "rabbit" (Rocket) after it extracts the Aether from Jane Foster, while Frigga is made aware of a future Thor from a different timeline. Mjölnir is borrowed from this timeline. And similar to the missing baseball glove from the Barton farmhouse, while minor, the large can of beer that Thor leaves behind in Asgard can potentially trigger a (hopefully minor) comedic butterfly-effect that will nevertheless still change the future.
*** '''2014''': (right before ''Film/GuardiansOfTheGalaxy'') Thanos and his forces (aside from Ronan and Korath) completely disappear from this timeline and are killed along with that timeline's Nebula in the main timeline, while the Gamora of this timeline lives on in the prime timeline, replacing her dead original future self. With this timeline's version of Gamora now in the main one, the Guardians of this timeline likely never form, especially since Peter Quill was knocked out before he could get the Power Stone (potentially giving the Kree time to get it after Cap puts it back).
*** '''2018''': [[TheLastOfTheseIsNotLikeTheOthers A baseball glove disappears from the Barton household.]] This might not have any significant effect on world events, but butterfly effect, so you never really know.
** This is also why Steve goes back to the various timelines to return their Infinity Stones and Mjölnir: without them, the bad guys would never be stopped in that timeline's version of ''Film/{{Doctor Strange|2016}}'' (Time), ''Film/{{Captain Marvel|2019}}'' (Space), ''Film/GuardiansOfTheGalaxy'' (Power), ''Film/ThorTheDarkWorld'' (Mjölnir), and so on. While there are likely some major and irrevocable changes, this will mitigate some of them a great deal.
* AlternateUniverse: This is the primary difference between scientific time travel (via the Quantum Realm) and magical time travel (as has been shown with the Time Stone). As explained by Professor Hulk and later the Ancient One, quantum time travel creates a new alternate reality that diverges at the point you arrive, so that everything that follows has no effect on the original timeline.
* AmazonBrigade: During the final battle, when the Avengers are relaying the Infinity Gauntlet towards the Quantum Tunnel, Spider-Man passes it off to Captain Marvel, who gets an escort from every single active female Avenger or ally: Okoye, Shuri, Scarlet Witch, Valkyrie, Gamora, Nebula, Mantis, the Wasp, and Pepper Potts in her Rescue suit.
* AmbiguousSituation: After Steve returns Mjölnir and the Infinity Stones, and goes to live in the past with Peggy Carter, did he create an AlternateTimeline, or was he part of the ''original'' timeline all along? Since the year Steve travels back to is 1948, this allows plenty of time for the ''Series/AgentCarter'' series to take place before Steve comes into the picture. The writers have suggested that Steve was Peggy's [[CanonCharacterAllAlong mystery husband all along]], but the directors have stated that Steve simply went to live in an alternate reality, leaving this situation up in the air.
* AmicableExes: After briefly touching on their quasi-relationship in ''Film/AvengersInfinityWar'', Natasha and Bruce have reached a version of this following the time skip.
* AndStarring: Theatrical posters only have the singular "With Creator/JoshBrolin as ComicBook/{{Thanos}}." The end credits to the film actually has [[UpToEleven enough people being credited this way]] that the list is as long as the cast listing for other films in the MCU: "Featuring Creator/VinDiesel as Groot, Creator/BradleyCooper as Rocket, with Creator/GwynethPaltrow, with Creator/RobertRedford, with Josh Brolin as Thanos, with Creator/ChrisPratt, and Creator/SamuelLJackson as Nick Fury." And ''then'' it concludes with the original six, including the actors' signatures along with the usual titles.
* AndTheAdventureContinues:
** While most of the Avengers' arcs are tied up with death or a happy retirement, Thor joins the Guardians of the Galaxy (at least temporarily) to do a cosmic version of WalkingTheEarth.
** Steve gives Sam the shield and deems him the new Captain America.
* AnimalMotifs: The ''Benatar'' resembles a swallow in the contre-jour shot where it is drifting around in space. Being a monogamous migrating bird, swallows are a symbol for loyalty, hope, and the safe return home after a long journey. Thanks to Captain Marvel, Tony and Nebula make it back home in one piece.
* AnswerCut:
** When Scott Lang discusses his plan with Cap and Black Widow, he seems to get the idea that they don't know how to help him. He asks, "So who do we go to?" Cut to a shot of Tony's new home as he walks out to look for Morgan.
** After Stark rejects them, Cap comments, "We're going to need a really big brain." Doubtfully, Scott asks, "Bigger than [Stark]'s?" Cut to a shot of Banner/Hulk eating his food, angled to show off his huge head first.
** When Rhodey and Nebula arrive on Morag, Nebula warns Rhodey that several people (including 2014 her) are also searching for the Power Stone at the same time. Rhodey asks, "Wait, where are you right now?" Cut to 2014 Nebula trying to fight aliens.
** Thousands of people arrive to the Avengers HQ battlefield via sorcerers' portals. Strange asks Wong, "Is that everyone?", to which Wong responds, "You wanted ''more''?" Then Giant-Man bursts out of the rubble with Rocket, Hulk, and Rhodey, and they all get in position to fight.
* AntiRoleModel: Howard Stark admits to "Howard Potts" (i.e. time-traveling Tony) that he is dreading the possibility of his son turning out like him, and hopes he becomes better than him.
* TheApocalypseBringsOutTheBestInPeople:
** Downplayed. The film doesn't call attention to this trope, but it seems to be in effect. Despite the elimination of half of all life in the universe, human civilization continues without collapsing into dystopia. This applies to some specific heroes in particular. Banner despite being a hero before the tragedy ultimately takes his defeats as a learning opportunity and reconciles his Banner/Hulk sides to become the best version of himself. Nebula goes on to fully complete her HeelFaceTurn by working with the heroes to rebuild and thwart the event.
** It's also subverted. While civilization overall seems to have managed to muddle through, people are still traumatized over five years later. People just going out on a date end up crying during the date, but this is considered so normal that they still schedule another one. From hints Carol gives during her briefing with Natasha, other planets aren't doing much better. The inability to move on is so bad that when 2014 Thanos shows up, he decides that the only way to get things moving again is to destroy ''everything'', and start the universe from scratch.
* ApocalypticLog: Tony Stark records a message on one of his helmets while drifting out in space. With his food and water gone, and his oxygen about to run out, he intends for it to be his final message.
-->'''Tony:''' Hey, Miss Potts. If you find this recording... don't feel bad about this.
* ArbitrarySkepticism: Discussed, when the Avengers talk about Scott's time travel idea which Nat really takes seriously, much to Scott's own amazement. Natasha points out she gets "emails from a raccoon" -- time travel wouldn't be hard for her to get behind.
* ArcWords:
** "Whatever it takes" for the surviving Avengers determined to bring back the people they lost to the Decimation. These are the words that Black Widow and Hawkeye repeat when they realize that the Soul Stone demands a sacrifice from one of them.
** "Move on" in the early part of the movie, as the characters try to adapt to the effects of the Decimation, and that they had no way of undoing it, at first. It's also relevant in how Thanos expresses disappointment at the heroes for trying to undo his future self's work.
** "I am inevitable" from Thanos. The line is first used by the retired Thanos defiantly saying that his work is irreversible to the Avengers. It is later repeated when Past Thanos watches the recording of his future death. And it is the last thing that Past Thanos says before realizing that Iron Man has the Infinity Stones and uses them to kill him and his army, thereby averting the "inevitable" altogether.
** "I am Iron Man": Going all the way back to the first Iron Man movie and the start of the MCU; Tony repeats it at the end of the third Iron Man movie, and repeats it one last time here, before he uses the Infinity Stones against Thanos and his army.
* AnArmAndALeg: When the remaining Avengers get the drop on Thanos on the Garden planet, the first thing done after immobilizing him is Thor cutting his gauntlet arm with Stormbreaker. The fact that Thanos never removed it despite the Infinity Gauntlet no longer sporting the Stones (and thus being now useless) hints that it had fused with his arm after its last use.
* ArtisticLicenseMartialArts: When Hawkeye's daughter is practicing archery with him she raises her elbow upwards when pulling back the bowstring instead of keeping it horizontal. Despite that she hits the target dead centre and Hawkeye compliments her technique.
* ArtisticLicensePhysics: At the beginning of the first act, the ''Benatar'' is out of fuel in the middle of outer space, completely motionless. While this would impact life support, the ship should still retain forward momentum, instead of being "dead in the water". Though there is little meaningful difference between being motionless as such and simply not moving quickly enough for the motion to be apparent, given the vastness of the void of space.
* AscendedExtra:
** Hawkeye has always been a supporting character, and of the original six Avengers, he's gotten the least time to shine out of anyone. Here he gets his own ''major'' plotline revolving around his relationship with Black Widow, and the scene of [[AdultFear his family disappearing]] while he's on a picnic with them is the [[DownerBeginning very first scene]] of the movie -- before even the Marvel logo!
** Ant-Man, when looked at from a broader scale. He is considered one of the main stars in the movie, and this may be a surprise as he wasn't introduced until the end of Phase 2. Both of his movies, while not slouches at the box-office overall, trail behind the other MCU stars and are relatively self-contained, while his role in ''Civil War'' was rather minor, not to mention that he sat out of ''Infinity War''. Here, while the movie also emphasizes the six founding Avengers, Ant-Man's involvement is ''very'' important to defeating Thanos. This is not unlike Doctor Strange's role in ''Infinity War''.
** Nebula. She started out as a secondary villain -- basically just there so Gamora had somebody to fight in the third act. Now she's one of the (many) central characters in the biggest film event in history, and half the plot hinges on her.
* AssShove: Thor's solution for [=NoobMaster69=]'s trolling is threatening to do this to him with his own arms.
* AssholeVictim: Thanos at the end of the first act may have just become a peaceful farmer in his retirement from being an omnicidal warlord, but you'll still likely not shed any tears over him when the Avengers ambush him, cut off his arm, and eventually decapitate him. Clint's crusade against the criminal underworld also applies, as he butchers any cartel, yakuza thug, or other criminal scumbag he comes across.
* AstralProjection: When Professor Hulk gets impatient with the Ancient One, she forces Banner out of the Hulk's body in astral form. Banner then converses with her while the Hulk is left sleeping on a chair.
* AudibleSharpness: Stormbreaker makes its usual sounds flying through the air, cutting through things...and opening Thor's beer.
* AudienceSurrogate: Scott acts as one throughout the film, being the guy completely shocked at how much the heroes and their world have changed since he last saw them, and desperate to get back what has been taken from them. Scott also bases his understanding of TimeTravel on popular movies rather than an understanding of the actual science that would be involved. Tony and Bruce use this to distinguish between more science-based TimeTravelTropes and those less based on (currently understood) science.
* AuraVision: Thor tries to trick Frigga into thinking that he's the Thor from her timeline, and fails miserably.
-->'''Frigga:''' I was raised by ''witches'', boy. I see with more than eyes, you know that.
* AvengersAssemble: Right before the final battle, Doctor Strange and a bunch of other sorcerers warp superheroes and various other warriors to the remains of the Avengers compound in order to fight off Thanos's invasion. The words are finally spoken by Cap, although he says it ''after'' everyone's assembled... which is actually true to the source material.

[[folder:B]]
* BackForTheFinale:
** Lots of characters return for the final battle, including all the heroes who died in the original Snap. This even extends to {{Mooks}} on both sides; Thanos brings Outriders from ''Film/AvengersInfinityWar'', Chitauri and Leviathans from ''Film/{{The Avengers|2012}}'', and Sakaarans from ''Film/GuardiansOfTheGalaxy''. The Avengers get Sorcerers from ''Film/DoctorStrange2016'', Asgardians from [[Film/{{Thor}} the]] ''[[Film/ThorTheDarkWorld Thor]]'' [[Film/ThorRagnarok films]], Ravagers ([[MyFriendsAndZoidberg and Howard the Duck]]) from ''Film/GuardiansOfTheGalaxyVol2'', and Wakandan warriors from ''Film/BlackPanther2018''.
** Also, many of those who died in previous films (or haven't been seen since) are seen again as the Avengers travel through time. In New York: Loki, Brock Rumlow, Agent Sitwell, Alexander Pierce, and the Ancient One. On Asgard: Frigga, Jane, and Loki again. On Lehigh Base: A younger Hank Pym, Howard Stark, and Edwin Jarvis. On Vormir: Red Skull. And an older version of Harley from ''Film/IronMan3'' appears at Tony's funeral.
** For the very first time, a character from the Marvel TV shows gets to migrate to the movies, when [[Series/AgentCarter Edwin Jarvis]] is shown chauffeuring Howard Stark at the Lehigh military base.
* BackFromTheDead:
** The quantum time travel device allows the Children of Thanos, all of whom were killed in ''Infinity War'', to return for the last battle with the Avengers. The same goes for Thanos, who is killed by Thor in the first act of the film, but is eventually replaced with a slightly younger counterpart from earlier in the timeline.
** In the finale, Hulk un-snaps everyone dusted in ''Infinity War'' back into existence, eventually leading to a final confrontation between the heroes of Earth and Thanos's forces.
** The quantum time travel device also brings back Gamora, as the Gamora of 2014 hadn't been killed by Thanos. However, since this is a Gamora from before she ever met Star-Lord, this causes a relationship reset.
* BackToBackBadasses: Tony and Pepper guard each other in true BattleCouple fashion during final battle so neither is snuck up on.
* BackToTheEarlyInstallment: Thanks to Thanos destroying the Infinity Stones after his infamous snap, the Avengers have to use time travel to go to the past where they still existed so they can undo the snap. To find them they go to the events of ''Film/{{The Avengers|2012}}'', ''Film/ThorTheDarkWorld'', and ''Film/GuardiansOfTheGalaxy''. We get to see them arrive during the 2012 Avengers' famous pose, and right at the start of Peter Quill going after the Power Stone.
* BadassArmy: The Avengers are joined at the climax of the film by ''practically every single heroic force'' introduced in the MCU, from the Guardians of the Galaxy, the Masters of the Mystic Arts, the Asgardians, the Ravagers, and the Wakandans to form one hell of an army of {{Superhero}}es, [[KungFuWizard Kung-Fu Wizards]], [[Myth/NorseMythology Norse gods]], SpacePirates, [[{{Afrofuturism}} Afrofuturist]] warriors, and [[TheLastOfTheseIsNotLikeTheOthers a gun-toting, talking]] [[Comicbook/HowardTheDuck duck in a suit]]. They clash with Thanos's own forces, consisting of the Chitauri, the Sakaarans and the Outriders.
* BadassBoast:
** In the finale, Wanda lands in front of Thanos with vengeance written on her face.
--->'''Wanda:''' You took.... ''everything'' from me.\\
'''Thanos:''' I don't even know who you are.\\
'''Wanda:''' ''You will.''
** Few boasts can hold a candle to Tony Stark’s FamousLastWords:
--->'''Thanos:''' I am inevitable.\\
'''Tony:''' '' And I... am... Iron Man.'' ''[snaps]''
* BadassFingersnap:
** Once the Avengers collect the Infinity Stones, Bruce does it to bring back everyone turned to dust.
** Once Thanos has the gauntlet and has taken out everyone trying to stop him, he snaps to fulfill his new plan, [[SubvertedTrope nothing happens]]. It turns out Tony took the stones, and does one to disintegrate Thanos and his forces.
* BadBadActing: When part of the Avengers time-travel to 2012 during the Battle of New York, they witness the Hulk throwing a fit. Professor Hulk is told to act like the Hulk to blend in, and he grumbles that it's "gratuitous", but he'll do it. He goes over to some vehicles and gives them a few unmotivated punches while lazily saying "roaaar".
* BadVibrations: Steve's bathroom mirror vibrates when Captain Marvel returns the ''Benatar'' to the Avengers Headquarters.
* BaitAndSwitch: Cap is once again [[Film/CaptainAmericaTheWinterSoldier inside an elevator full of HYDRA infiltrators within S.H.I.E.L.D.]] who refuse to give him Loki's scepter and get suspicious of his insistence. Looks like we'll get another elevator fight, right? Nope, Steve instead [[TrustPassword whispers "Hail HYDRA" in Sitwell's ear]]. Suddenly they all think he's a fellow sleeper agent and hand him the case, no questions asked.
* {{Bathos}}: At the dramatic climax of the epic three-hour-long extravaganza, 2014 Thanos reclaims the Infinity Gauntlet, dramatically declares "''I am inevitable''", and [[TheBadGuyWins snaps his fingers]] ''[[AllForNothing again]]'', and...nothing happens. No flash of light, no dramatic explosion of energy, just a tiny, [[FailedAttemptAtDrama hilariously anticlimactic]] ''clink'' of metal. [[MusicalisInterruptus Even the music cuts out]] as soon as he snaps his fingers. And then the arrogant smile [[OhCrap vanishes from Thanos's face]] as he looks over and sees that ''Tony Stark has the Infinity Stones.''
* BattleCouple:
** Couple Tony Stark and Pepper Potts suit up and blast through Thanos's forces. This includes a BackToBackBadass shot.
** Scott and Hope get such a moment, the Wasp helping Ant-Man move through the battlefield by flying.
* BattleCry:
** After emerging, revived, through a portal onto the final battlefield, T'Challa leads the approaching Wakandan army in chanting "YIBAMBE!" ("hold the line"), [[MeaningfulEcho reprising the similar moment]] from ''Infinity War''.
** And of course...
--->'''Captain America:''' ''[backed by every living hero of the movies, facing down the armies of Thanos]'' '''AVENGERS!''' ''[summons Mjölnir]'' ''Assemble.''
* BattleInTheRain: Ronin vs. Akihiko in Japan while rain falls like the anguish in the former's heart.
* BeardOfSorrow: Thor, having wallowed in shame and self-pity for five years because he failed to kill Thanos in Wakanda, has grown a large, unkempt beard and is noticeably out of shape. Inverted with Steve Rogers, who shaves his beard off after his darkest defeat.
* BearHug: Upon meeting him again for the first time in years, Thor hugs Rocket enthusiastically. Rocket doesn't appreciate being pressed against Thor's beer belly, though.
* {{Beatnik}}: When Tony Stark and Steve Rogers go back to 1970 to retrieve the Tesseract and additional Pym Particles, Tony is mistaken for a beatnik by his own father because of his beard.
* BewareTheSillyOnes: Scott Lang is comic relief for most of the movie, even though he's very important for the plot. Come the final battle, though, and as Giant-Man he punches Leviathans out of the sky and ''crushes'' Cull Obsidian (the strongest of Thanos's children in the previous movie) underfoot.
* BigBad: Thanos, once again, is the villain the heroes need to defeat in order to bring back half of the universe. In a subversion, the Thanos that wiped out half the universe is killed in the opening act of the film, but this does nothing to undo the damage he did, and the movie instead focuses on trying to pull ''that'' off, specifically a journey for the heroes to bring back their loved ones. It is a time-displaced Thanos from 2014 that takes the role of BigBad instead, after he learns the heroes are trying to undo his upcoming victory. Thanos becomes an even bigger bad, as now he isn't just trying to do a 50% depopulation, but totally wipe out the universe and restart it from the beginning.
* BigBadassBattleSequence: The Battle of Earth, a massive action scene involving '''40''' characters, all of whom have names and backstories. It's been hyped as one of the movie's selling points, even though none of it is shown off in the ad campaign for the film. It consists of pretty much every heroic force shown in the Marvel films coming together in one final clash against the Mad Titan's army amidst the ruins of the Avengers facility.
* BigDamnHeroes:
** When Tony and Nebula are left drifting through space in the ''Benatar'', Captain Marvel finds the ship and returns them safely to Earth.
** When Thanos's past self attacks the Avengers headquarters, Banner, Rhodey and Rocket are trapped in a section of the base about to be either crushed by debris or drowned. Fortunately, Scott is able to save them just in time for them to join the final battle.
** Steve gets his own during Thor and Thanos's fight to the death, showing up to save the Asgardians with Mjölnir in hand.
** Perhaps the '''biggest damn hero moment''' in the MCU happens right at the top of the final battle. When Captain America comes face-to-face with Thanos's enormous army, everything appears to be a lost cause... until Cap hears Sam Wilson's voice call out [[ContinuityNod "On your left"]]. [[TheCavalry Cue every resurrected superhero alongside Asgardians, Masters of the Mystic Arts, the Ravagers, Wakandans, and more]] emerging from portals to create an army of their own.
** Cull Obsidian gets Korg in a headlock and is clearly overpowering him, but Drax runs in to start stabbing his back, giving Korg an opening to fight back.
** Spider-Man gets one when he saves Iron Man from Cull Obsidian by pulling TheBrute away from him for Giant-Man to step on and kill.
** Captain Marvel again in the climax, when her presence alerts Thanos's ship and they stop their bombardment on the battlefield to focus on her. She then destroys the entire ship herself in a matter of seconds.
** Rocket is about to be devoured by a huge flying monster when it and the rest of Thanos's entire army is ReducedToDust.
* TheBigDamnKiss: ''Endgame'' closes on Steve and Peggy passionately kissing while dancing to the tune of "It's Been a Long, Long Time" when he goes to 1948, fulfilling a lost romance that has endured for most of the saga's history.
* BigDamnReunion: Towards the end of the film. Cap is all alone to face Thanos's massive army, until the resurrected Sam Wilson comes in, along with every previously snapped hero for a 5 years overdue reunion.
* BigGuyRodeo: As the final battle gets heated, Drax the Destroyer jumps on Cull Obsidian's back to stab him and help save Korg, who the former had put in a headlock.
* BigYes:
** A comedic one, when 2012 Thor revives 2012 Tony with MagicalDefibrillator.
** Rocket shouts "OH, YEAH!" when Captain Marvel enters the battle and destroys the ''Sanctuary II''.
* BittersweetEnding:
** The Avengers finally repair the damage Thanos has done to the universe at the end of ''Infinity War'' by traveling back in time to retrieve the Infinity Stones across different timelines, reviving everyone who got dusted by Thanos's fingersnap, and culminating in Tony using his own Infinity Gauntlet to, in turn, fingersnap Thanos and his army into oblivion. Unfortunately, their victory came at a steep price: Natasha sacrifices herself to help Clint re-acquire the Soul Stone in Vormir, Tony dies using the Stones on Thanos, and Steve, having returned the Stones to their original timelines, chooses to stay in the 1940s and live the rest of his days in married retirement with Peggy, though at least he lives long enough to pass his shield and mantle to Sam Wilson. Additionally, the Avengers H.Q. has been completely annihilated by Thanos's forces, and the future of the team itself is left ambiguous at the end of the film.
** Furthermore, things are not fully restored to pre-''Infinity War'' days. While the 2014 version of Gamora lives on in the current timeline, the version of Gamora from the original timeline is dead for good, something that Star-Lord is clearly upset over even though he tries to hide it, since this Gamora never fell in love with him. The Vision is also still destroyed, and without the Mind Stone, there is not a clear way to bring him back -- although Wanda has seemingly made peace with this.
** On a smaller note, even after bringing everyone back, there's the fact that they lost five whole years of time with their loved ones. Like Scott losing out on seeing his little girl grow into the teenager she was when she opened the door for him. Now all of the returned victims have to adjust to a world that's moved on without them.
** Lastly, with the Infinity Stones reduced to atoms, the universe is open to all sorts of threats the stones had previously been used to protect them from, for instance extra-dimensional {{Eldritch Abomination}}s like [[Characters/MCUDarkDimension Dormammu]].
* BodyguardingABadass: During the final battle, all the major female characters show up to give Carol backup while she makes a run towards Scott's time machine, even though she's by a wide margin the most powerful person on the planet and had just [[DynamicEntry arrived by plowing through a massive starship]].
* BodyHorror: Using the full power of the Infinity Gauntlet isn't good for anyone's health.
** Thanos, after using the Stones twice, is reduced to a broken, limping wreck, the entire left side of his body burnt and blackened and his gauntlet arm essentially lame by his side. The fact that he didn't remove the now useless gauntlet also implies it has fused with his flesh.
** Using the Stones just once is enough to scar Professor Hulk the same way, and fatally injure Tony Stark.

%%
* BookEnds:
** The original six Avengers from ''Film/{{The Avengers|2012}}'' all survived the events of ''Infinity War'', and reassemble (and team up with the other surviving heroes) to put an end to Thanos's conquest for universal "[[KillEmAll balance]]" that started with the Chitauri attack on New York City.
** Character design-wise, Captain America and Iron Man, the MCU's two biggest players, whose stories are wrapped up in this movie, wear outfits that look almost exactly like their classic comic book designs instead of the MCU's signature "modernized" look. Tony doubles up by having a similar black tank top to the one he had in the original ''Film/IronMan1''.
** Tony Stark's iconic "[[Film/TheAvengers2012 If we can't protect the Earth, you can be damned well sure we'll avenge it]]" line goes full circle considering they indeed ''couldn't'' protect the Earth, but are now seeking Thanos to avenge the fallen.
** Iron Man is back in the same kind of dilemma he was in at the beginning of [[Film/IronMan1 his first movie]]: trapped in a prison on borrowed time, with his only hope for survival depending entirely upon someone else helping him out, surviving only off of materials that he has within his prison. As an added bonus, he's even wearing the same kind of shirt that he did when he was in that cave in Afghanistan.
** Cap is wearing the same S.H.I.E.L.D. uniform that he wore in ''Film/CaptainAmericaTheWinterSoldier'' -- the first film in the Russo Brothers' MCU run. ''Endgame'' happens to be the last in the Russos' MCU run.
** Tony's FamousLastWords, and the ones that finally mark the end of the battle, are the same words that ended [[Film/IronMan1 the first movie]]: "I am Iron Man."
** Also going back to his first movie, there the arc reactor turned back on after the climactic battle showing he survived. Here it turns off to signify his death.
** Spanning back to ''[[Film/AvengersInfinityWar Infinity War]]'', the earlier film ends with Thanos watching the sunrise, as he smiles in pride having accomplished his goal. This film ends with Thanos watching the sunrise, as he bows his head in shame having failed.
** It also closes out his very first appearance in ''Film/{{The Avengers|2012}}''. There he stood up and smiled at the thought of facing the Avengers. Here he sits down and bows his head defeated by the Avengers.
** Moments before his death, present-day Thanos defiantly proclaims "I am inevitable" to the Avengers. In the final battle, before [[OhCrap he realizes that Iron Man has the Infinity Stones]], Past Thanos arrogantly proclaims "I am inevitable". It was definitely intentional on his part, since he had watched Nebula's memory of 2018 Thanos's death in which some of his last words were declaring "I am inevitable" to proclaim his victory, and believed he was about to succeed again.
** The song that closes out the film, "It's Been a Long, Long Time", was previously used in Joe and Anthony Russo's first Marvel movie, ''Film/CaptainAmericaTheWinterSoldier''.
** After the credits, the sound of Tony hammering together his very first suit from all the way back in the opening act of ''Film/IronMan1'' plays.
** Tony begins the film recording a potential ApocalypticLog / VideoWill for Pepper in case of his death. His final scene has the cast viewing another one he made five years later for her and Morgan at his actual funeral.
** While Thanos has gained and lost a multitude of archnemeses in his 46-years-and-counting comic book history, he was first introduced in the pages of ''ComicBook/IronMan'' Vol. 1 #55. Therefore, it is only fitting that Iron Man himself would see him out. Bonus points for having his creator, Jim Starlin, [[CreatorCameo make an appearance for this event]].
** ''Film/CaptainAmericaTheFirstAvenger'' -- Steve Rogers' MCU debut -- had him begin his career as Captain America and fight the Red Skull, who was wielding an Infinity Stone (the Tesseract/Space Stone), and then get frozen into the 21st century. ''Endgame'' -- which is meant to close out Rogers's CharacterArc -- ends with him travelling ''back'' in time and return the Infinity Stones back to their proper eras, including Vormir in 2014 -- which was where the Red Skull ended up after ''The First Avenger''.
* BraidsOfBarbarism: Thor gets braids in his hair and beard when he powers himself up with lightning before the final battle.
* BrickJoke: Both in-movie and on a franchise-wide level.
** Within the film itself:
*** Rocket and Nebula end up finding a garbage scow of a ship that Danvers pinged as hostile. On Vormir, Nat, who had been point for the expeditions Nebula, Rocket and Carol were on at the time, responded to Clint's observation of Rocket ''not'' being a raccoon by saying "he eats garbage" as well as mentioning to Scott that she got "e-mails from a raccoon" which made nothing sound crazy to her. This also hearkens back to the multiple times Rocket asks what a raccoon is whenever someone calls him it (normally Quill).
*** Scott is not happy that Tony refused to help the team at first, and reminds him later in the movie after the botched attempt to steal the Tesseract.
---->'''Scott:''' You're repeating yourself! You're repeating yourself!
*** ''Back to the Future'': Tony is thinking Scott is basing his theory for time travel on this film, which Scott denies. When Bruce debunks every theory he and Rhodey had, he quips "So ''Back to the Future'' is a bunch of bullshit??"
** Carrying over from other movies:
*** Steve Rogers making Mjölnir budge during the "lift the hammer" party game from ''Age of Ultron'' pays off when Cap finally lifts and wields Mjölnir in the finale, with Thor gleefully saying "I knew it."
*** Scott tells Hank his days of "breaking into places and stealing shit are done" in ''Ant-man''. Played with in this film; he and the Avengers break into other timelines and steal the Stones (and Mjölnir).
*** When Clint returns from his time travel test run, Scott can be seen in the background holding some orange slices, the same snack he requested in ''[[Film/CaptainAmericaCivilWar Civil War]]''.
*** Steve Rogers is shown [[NotSoAboveItAll swearing several times]], despite being kidded for reprimanding others for their language in ''Age of Ultron''.
*** After being [[InterruptedByTheEnd teased]] in ''Age of Ultron'', Steve Rogers finally says "Avengers Assemble!"
*** After Rocket steals the Aether, he's chased down by a horde of Asgardian guards who cry, "get that rabbit!" just like Thor has mistaken Rocket for a rabbit.
*** Tony Stark being reluctant to call his hug to Peter at the start of ''Homecoming'' a hug, comes back when he unambiguously hugs him.
*** In a darker vein, Doctor Strange saying he wouldn't hesitate to sacrifice either Stark or Spider-Man if it meant saving the world, becomes this when Strange confirms to Stark at the end that the one timeline in which Thanos is defeated ultimately rested on Stark performing a HeroicSacrifice. Strange really wasn't kidding around.
*** In the same darker vein, Tony finally disproves Steve's argument from the first movie that Tony will never make the big sacrifice (though it's not like he didn't try to do so in the first movie).
*** Likewise, Tony's argument (as well as Red Skull's) that everything special about Steve came from the super-soldier serum is proven definitively wrong by Mjölnir, and by extension Odin himself.
*** Early in the film at Tony's house, he finds Morgan wearing the helmet for the suit of armor he made Pepper, and jokingly complains that "Mommy never wears anything I make her." Guess who shows up, in a suit of armor, at the final battle?
*** During the tarmac fight in ''Film/CaptainAmericaCivilWar'', Hawkeye introduced himself to T'Challa as Clint, and T'Challa answered, "I don't care." During the final battle, when Hawkeye is carrying the nano-gauntlet with the Infinity Stones, only to be surrounded by Thanos's forces, T'Challa remembers his name and says, "Clint, give it to me!"
* BringIt: Aside from a moment of surprise, Thanos's reaction to the Avengers bringing in a massive army of allies in the form of the Wakandans, Asgardians, Ravagers, Khamar-Taj, and more, which then charges at him, is to simply lift his blade with a satisfied smile and order his army to do likewise.
* BrokeYourArmPunchingOutCthulhu: Tony succeeds in defeating Thanos and his forces by snapping with the Infinity Stones, but wielding their power completely fries his human body to the point of dying just a few minutes after using them.
* BrutalHonesty: More than one character tells Thor either that he failed, or that he is a failure.
-->'''Thor:''' That's a little bit harsh...
* TheBusCameBack:
** After sitting out ''Infinity War'', Hawkeye and Ant-Man return.
** Harley Keener, the kid from ''Iron Man 3'', makes a reappearance at Tony Stark's funeral.
** When Thor and Rocket time travel back to the events of ''Film/ThorTheDarkWorld'', both Jane Foster and Frigga show up. Along with Mjölnir.
** The Ancient One from ''Film/{{Doctor Strange|2016}}'' appears in the 2012 New York timeline, four years before Stephen Strange started practicing the Mystic Arts with her.
** Likewise, Brock Rumlow, Jasper Sitwell, and Alexander Pierce (not yet unmasked as ComicBook/{{HYDRA}} moles) show up when Tony, Steve, and Scott bump into them in the aftermath of the Battle of New York).
* BusCrash: According to the Russos, both [[Film/TheIncredibleHulk Betty Ross]] and [[Film/{{Thor}} Lady]] [[Film/ThorTheDarkWorld Sif]] were [[KilledOffscreen turned to dust]] by the end of ''Infinity War''. Although her demise wasn't shown in ''Infinity War'', [[Film/BlackPanther2018 Shuri]] was another victim. [[FreezeFrameBonus Freeze Frame Bonuses]] confirm that Erik Selvig and Sharon Carter also died.
* ButForMeItWasTuesday: This is played with. 2018 Thanos killed Vision to get the Mind Stone. When Wanda is brought back, she is furious at Thanos, even though she is speaking to his 2014 counterpart, and [[FishOutOfTemporalWater he genuinely doesn't know who she is]].
* ButtMonkey:
** Star-Lord. His past incarnation of him is knocked out by Rhodey after both he and Nebula call him an idiot. His present incarnation after being revived runs into the past Gamora, who [[GroinAttack kicks him in the groin]] when he moves on her because she doesn't know him yet, and finally, his position as the leader of the Guardians is contested yet again when Thor tags along with the crew in the ending, in spite of Thor still being horrendously out-of-shape and still recovering from his depression. Peter Quill just can't catch a break.
** Even if he is essentially a HopeBringer for the heroes, Scott fares worse than Peter in this regard since he has a much larger role. Getting hit with both RapidAging and [[FountainOfYouth de-aging]] one after another in a single scene is just one of the many embarassments he goes through.
** Cull Obsidian gets manhandled pretty badly during the Battle of Earth. Even though he takes point in leading Thanos's army forward, he is immediately knocked down by Cap with Mjölnir before he can even land a hit on someone. Cull gets back up and manages to get Korg in a headlock, but then Drax hops on his back to stab him repeatedly, and Korg is able to get free and smack him in the face. Finally, Cull once again attacks Iron Man, but Spider-Man is able to hold him in place with his webs long enough for Giant-Man to fatally crush him under his foot. For all his being the biggest and toughest of Thanos's children, Cull barely lasts a ''minute'' in the final battle.

%%
* CallBack:
** Tony mentions his nightmare from ''Film/AvengersAgeOfUltron'' and bitterly references his "suit of armor around the world" plan and that promised they would fight and lose [[TheTeam together as a team]]. (See CallingTheOldManOut below.)
** When the team have Thanos restrained at the beginning of the movie, Thor decapitates him. His response when asked "what did you do"?
--->'''Thor:''' ''[bitterly]'' I went for the head.
** Scott tries to remind the Avengers of his presence with his contributions to the Leipzig-Halle airport fight in ''Film/CaptainAmericaCivilWar''.
** At the end of ''Film/CaptainAmericaCivilWar'', Steve surrendered the shield after Tony shouted, "That shield doesn't belong to you! My father made it!" When Tony returns to Avengers Compound to assist with their plan to retrieve the Infinity Stones, he returns Steve's shield, commenting, "He made it for you."
** In ''Film/ThorRagnarok'', Odin tells Thor in a vision that the field in Norway where he died could be Asgard, because Asgard is its people. This is where the surviving Asgardians settle to establish "New Asgard".
** During their attempt to recruit a drunken and despondent Thor, Bruce mentions how much [[Film/ThorRagnarok Thor's help on Sakaar]] meant to him when he was trying to merge his brains with the Hulk's brawn.
** The events of the Time Heist feature call-backs to the films that took place during those times along with other films in the MCU:
*** Captain America dons his original outfit from the first ''[[Film/TheAvengers2012 Avengers]]'' movie at one point in the film. He does this to blend in when he, Ant-Man, Hulk and Iron Man travel back to the aftermath of the Battle of New York so that they can get the Space and Mind Stones.
*** While trying to get the scepter, [[Film/CaptainAmericaTheWinterSoldier Cap is in an elevator full of HYDRA agents (including Rumlow) who are trying to act like everything's normal, but are clearly ready for a fight]]. This time he bluffs his way out.
*** When Professor Hulk tries to take the Eye of Agamotto from the Ancient One without so much as a by-your-leave, she calms him down by knocking his astral form out of his body, like she did to [[Film/DoctorStrange2016 Stephen Strange]] when he got too exasperating for his own good.
*** Thor and Rocket are tasked with retrieving the Reality Stone from Asgard just before it is attacked by the Dark Elves during ''Film/ThorTheDarkWorld''. This allows Thor to have a heart-to-heart with his mother Frigga shortly before her predestined death.
*** War Machine and Nebula head to the planet Morag from the beginning of ''Film/GuardiansOfTheGalaxy'' so that they can get the Power Stone before the past version of Star-Lord steals it.
*** In the 1970s, Tony and Steve end up at the army base where S.H.I.E.L.D. set up shop after WWII. Tony doesn't know where the entryway is. But Steve, however, does from his time in ''Film/CaptainAmericaTheWinterSoldier'', pointing out the same munitions bunker entryway that he had gone (or will go) through.
** The mambo drum rattle used to kick off Luis' stories in ''Film/AntMan'' can be heard during pivotal moments of the Time Heist, like Scott breaking into past Tony's arc reactor.
** The Hulk ends up being the one to use the Infinity Stones to resurrect everyone who died in the decimation, as the Stones give off harmful gamma radiation that only his body can withstand. Earlier, when searching for the Tesseract at the S.H.I.E.L.D. facilities, a FreezeFrameBonus shows that Tony's glasses are specifically tracking a gamma radiation signature. Back in the first ''Avengers'' movie, S.H.I.E.L.D. tracked down Bruce because the Tesseract emitted gamma radiation that he knew all about. In the same film, Tony mused that maybe Bruce had survived the gamma accident that turned him into the Hulk for a reason, and it looks like he was correct.
** Thor uses his lightning to power up Tony's armor during the final battle with Thanos, a nod to the scene in the first ''Avengers'' movie where he accidentally charged up the armor during his initial fight with Tony.
** During the final battle, Captain America is able to lift Mjölnir, referencing the scene where he was actually able to slightly budge the hammer in ''Film/AvengersAgeOfUltron''.
** One of the moves that Steve uses involves his shield and Mjölnir colliding behind Thanos during his fight before the big battle begins, the shockwave throwing him off his balance. In the first two ''Avengers'' films, this combo move was performed with both Thor and Steve (in the first film, it's discovered during the first fight between Tony and Thor and used during the Battle of New York. In the second film, Steve and Thor use it while the Avengers assault the HYDRA castle at the start of the film. The move Steve does in this film marks the third and final time it's seen on screen).
** Spider-Man activates the [[Film/SpiderManHomecoming Instant Kill Mode]] in the final battle.
** What are Tony Stark's [[FamousLastWords last words]] before using the Infinity Gauntlet to snap Thanos and his army into oblivion? ''"I am Iron Man!"'' -- the same words that he said when he first revealed his identity to the world in ''Film/IronMan1''. [[BookEnds He ends his journey with the same bold declaration that began it.]]
** Also a slight BookEnd of sorts, in ''Film/IronMan1'', Pepper threatened to quit when she saw Tony endangering himself by wearing the Iron Man suit, but Tony convinced her to stay by informing her of his change of heart. Here, he does die in battle, but as a HeroicSacrifice rather than getting himself killed like she feared, and she's the last person with him before he passes.
--->'''Pepper:''' ''[in 2008]'' [[DramaticIrony You're gonna kill yourself, Tony, I'm not gonna be a part of it.]]

* CallToAgriculture:
** As seen in ''Infinity War'', after dusting half the universe, Thanos moved to a place called "The Garden", where he's shown harvesting crops and cooking them. When the Avengers learn of his location, Rhodey comments, "That's cute, Thanos has a retirement plan".
** Hawkeye has been toying with retiring from the secret agent/superhero life to be with his wife and kids on the farm since the end of ''Age of Ultron''. Once the snap is reversed and he ''has'' a wife and kids back on the farm again, he decides to make another go at it.
* CallingTheOldManOut: Tony does this to Steve ([[OlderThanTheyLook who at this point is nearly 100 years old]]) over his broken promise from ''Film/AvengersAgeOfUltron'' to fight together to combat any threat from space rather than trust a "suit of armor around the world."
-->'''Tony:''' I saw this coming a few years back. I didn't wanna believe it -- thought I was dreaming. ... And I remember telling all of you that what we needed was a suit of armor around the world. Remember that? Whether it impacted our precious freedoms or not -- that's what we needed!\\
'''Steve:''' Well, that didn't work out, did it?\\
'''Tony:''' I said we'd lose. You said, "We'll do that together too." And guess what, Cap? We lost, and you weren't there. ... I got nothing for you, Cap! I got no coordinates, no clues, no strategies, no options. Zero. Zip. Nada. No trust, liar.
* TheCameo:
** One of the Russo brothers, Joe Russo, cameos as the grieving man attending a group therapy session with Captain America after the five years timeskip. Also present is Creator/JimStarlin, creator of Thanos and writer/artist of ''The Infinity Saga'' in the comics.
** Creator/StanLee has one, [[OncePerEpisode as usual]], where during the time travel to 1970 in New Jersey, he drives next to an army base, shouting "Make love, not war," a reference to his counterculture fanbase at the time. It is one of the last live-action cameos he filmed before he passed away, and is officially his final cameo in the Marvel Cinematic Universe.[[note]]Lee's likeness appeared in ''WesternAnimation/RalphBreaksTheInternet'' and he voiced a cameo in ''WesternAnimation/SpiderManIntoTheSpiderVerse''. Creator/JamesGunn also helped him film a number of cameos for Marvel movies before other Marvel movies actually started production.[[/note]] Worth noting is that the woman who is in the car with him is a de-aged version of his wife, portrayed entirely through CGI due to Joan Lee's death in 2017.
** In the ongoing tradition of actors from ''Series/{{Community}}'' appearing in the MCU, Yvette Nicole Brown shows up in the S.H.I.E.L.D. facility when Steve and Tony infiltrate it in 1970.
** Creator/KenJeong (also from ''Community'') appears as the security guard for the deep storage facility where the "disgusting van" has been sitting for 5 years.
** Howard the Duck can be seen in the background during the final battle.
** Creator/HiroyukiSanada is the yakuza that Ronin hunts and kills right before Nat recruits him.
** One of the people at Stark's funeral is Harley Keener, aka the kid who helped Tony in ''Film/IronMan3'', once again played by Ty Simpkins. Quite a few viewers were caught off guard since it had been six years since he was last seen.
* CantTakeCriticism: Upon finding out [[DespairEventHorizon just how people feel]] about his "balancing" of the universe in [[Film/AvengersInfinityWar the previous film]], as well as the fact that the Avengers are trying to undo it, Thanos [[JumpingOffTheSlipperySlope goes from simply misguided to completely insane]]. A few minutes of criticism is all it takes to make him decide to [[OmnicidalManiac kill the whole the universe]] and make a new world that ''will'' [[ItsAllAboutMe appreciate his actions and love him as a hero]].
* CastingGag:
** The two cast members of ''Series/ParksAndRecreation'' (Creator/ChrisPratt and Creator/PaulRudd) are dismissed as idiots by Nebula and Rhodey. Fittingly, both their characters (Andy Dwyer and Bobby Newport) are [[TheDitz ditzy]] [[ManChild manchildren]], but [[NiceGuy nice guys]].
** Also, the[[invoked]] [[MemeticMutation memetically]] [[OlderThanTheyLook ageless]] Creator/PaulRudd plays the character who accidentally travels five years into the future and does not age, while the others who survived the snap have aged visibly.
* CastFromHitPoints: Using the Infinity Gauntlet extracts a heavy toll. Thanos is crippled from the combined efforts of the Snap and his subsequent destruction of the Stones, Hulk is wounded and weakened after donning the Stark Gauntlet despite his great endurance and innate resistance to the gamma radiation released by its use, and Tony's attempt at using the Gauntlet -- though ultimately successful -- [[HeroicRROD kills him, implicitly by burning out his heart]].
* TheCavalry: An entire army of Wakandans, New Asgardians (which include Korg and Miek among them), Masters of the Mystic Arts, and Ravagers (among other groups), united behind the Avengers, charge across the field against the hordes of Thanos's forces.
* CelebrityParadox:
** The time-travel films mentioned when the Avengers discuss using the Quantum Realm to go to the past:
*** ''Film/HotTubTimeMachine'' stars Creator/SebastianStan, who plays Bucky.
*** ''Film/StarTrek2009'' stars Creator/ZoeSaldana, who plays Gamora, and Creator/KarlUrban, who played Skurge, and also features Creator/ChrisHemsworth, who plays Thor. The greater franchise features quite a few actors who appeared in the MCU such as Creator/BenedictCumberbatch, who plays Doctor Strange, and Creator/IdrisElba, who plays Heimdall.
*** If they mean the ''Film/{{A Wrinkle in Time|2018}}'' film released in 2018 and not the books, that film stars Creator/MichaelPena, who plays Scott's friend Luis.
*** Scott suggests ''Franchise/DieHard''. Creator/WilliamSadler, who was in ''Film/DieHard2'', plays President Matthew Ellis. Creator/SamuelLJackson, who was in ''Film/DieHardWithAVengeance'', plays Nick Fury.
** Thor's looks after five years of letting himself go and [[DrowningMySorrows drinking like crazy]] make him resemble [[Film/TheBigLebowski the Dude]] so much that Tony even snarkily calls him "Lebowski" at one point. [[Creator/JeffBridges The Dude himself]] played the BigBad Obadiah Stane all the way back in 2008's ''Film/IronMan1''.
** Korg can be seen playing ''VideoGame/{{Fortnite}}'', a video game in which Thanos was playable during a limited-time event.
* CentralTheme: Second chances. You may have failed once, but never give up. Use your failure to create an even better success.
* CerebusRollercoaster: The second arc of the movie (the Time Heist) has significantly more humor and is more brightly lit compared to the somber first act and the apocalyptic final arc because a 2014 version of Thanos invades Earth. However, the arc itself whiplashes back to serious during Black Widow's sacrifice.
* CharacterDeath: Though all those that were dusted in the previous film return, those that died otherwise (Loki, Heimdall, Gamora, Vision) remain deceased, albeit a past version of Gamora lives. On top of these, Natasha sacrifices herself so Clint can take the Soul Stone, with no hope of bringing her back. The final death in the film is Tony Stark himself, having used the Infinity Stones to wipe out Thanos's forces at the cost of his own life.
* CharacterDevelopment:
** Steve Rogers's loosening up over time is demonstrated when he travels to 2012. Rather than fight all the HYDRA agents in the elevator to get the scepter as he would have done a few years ago, he says "Hail HYDRA" to convince them to just hand it over. Later, he curses when he encounters his 2012 self and knows a fight is inevitable. During the ensuing scuffle, Steve is shown to be a CombatPragmatist compared to his past self when he says, "Bucky's still alive!", causing 2012 Steve to let his guard down and allowing present-day Steve to escape the chokehold and knock him out with the scepter.
** Thor's maturation from a pompous, arrogant braggart and BoisterousBruiser to a grieving, tormented survivor to a noble, selfless, and modest warrior is highlighted in the final battle. In ''[[Film/AvengersAgeOfUltron Age of Ultron]]'', Cap merely ''nudging'' Mjölnir was enough to make Thor [[OhCrap momentarily panic]] because he had built his entire concept of self-worth around being the only person [[OnlyTheChosenMayWield worthy of wielding the hammer]]. In ''Endgame'', there's not a trace of jealousy in him when Thor sees Captain America swinging Mjölnir around like he's had it for years, and he joyously says "I knew it." He even ''prefers'' Steve use Mjölnir in battle while he use Stormbreaker, because he knows he's not [[Film/ThorRagnarok Thor, God of Hammers]] and he's [[SoProudOfYou delighted to see his friend proven worthy.]]
** Nebula's Character Development is given a measuring stick to show how far she's come by this point when she faces her 2014 self, still fanatically loyal to Thanos.
** A smaller case, but nonetheless notable. Pepper has always been a case of WetBlanketWife towards Tony, [[Film/CaptainAmericaCivilWar even leaving him at one point]] when [[Film/AvengersAgeOfUltron he failed]] to fulfill his promise to [[Film/IronMan3 fully retire]]. While she does [[Film/SpiderManHomecoming get back together with him]], even when we last see her in ''Infinity War'', she still has shades of being a WetBlanketWife towards him when pointing out his arc reactor. In her two most prominent scenes here, however, we see that Pepper has long moved past that and, in fact, is the one who encourages Tony to help undo the Snap now that he knows the way to do so, citing both her acceptance that she could never stop Tony before, and that him not going through with this will haunt him in his sleep. It's telling that her last words to him as he dies from using the Gauntlet are not of pleas for him to stay alive, but of genuine assurance that he did everything he could and he can now rest. The fact that she [[BattleCouple willingly joins the final battle in the Rescue Armor]], despite Tony believing she would never wear it, shows how much she herself has grown.
* ChekhovsArmy:
** In the final battle against Thanos and his forces, every single hero who appeared in films prior (minus ones whose [[KilledOffForReal deaths are permanent]], like Natasha, Vision, or Heimdall) and their allies show up to assist the Avengers, forming a massive army spanning multiple alien races, gods, sorcerers, and technologically augmented humans.
** The film itself features many past characters (who are dead at the present point in the story saga) through time travel, such as Howard Stark, Loki, Peggy Carter, Frigga, the Ancient One, and Alexander Pierce.
* ChekhovsClassroom: Scott tells everyone that they only have one vial of Pym particles left since they lost Hank Pym to the Snap, which inspires Steve to find the part of the S.H.I.E.L.D. facility where Hank worked in 1970, and steal some fresh vials.
* ChekhovsGun:
** Hank Pym mentioned many times in the two Ant-Man films that the time and space work differently in the Quantum Realm and his wife even mentioned that there are time vortexes in there. This give Scott Lang the idea to use time travel to reverse the damages Thanos caused.
** Janet Van Dyne's prolonged stay in the Quantum Realm has given her Quantum Powers which, among other things, allowed her to stablize the molecules of those who are suffering from quantum displacement. Similarly, Scott was stuck in the Quantum Realm for five years (or five hours from his perspective) and while it is not explored, it most likely changes him as well, which explains how he is able to stay as Giant-Man for longer periods than before without showing any signs of exhaustion.
** In 2012, following the events of the New York battle, the Hulk is forced to take the stairs after the Avengers insist he won't fit in the elevator, and he angrily does so. Later, he swings the door open as Tony is about to walk away with the Tesseract, knocking him out and allowing Loki to escape with it.
** One which spans multiple movies: while trying to stop Thanos's forces from reaching the new Infinity Gauntlet, Spider-Man finally sees fit to activate [[Film/SpiderManHomecoming Instant Kill Mode]].
** While Tony's daughter Morgan plays with Pepper's Rescue mask, he tells her that Pepper doesn't wear it. During the final battle, she does.
** At the end of ''Infinity War'', after handing over the time stone to Thanos, Doctor Strange breaks down while apologizing to Tony Stark, saying it was the only way. ''Endgame'' reveals that he wasn't just apologizing for handing over the stone, but for setting in motion a plan that will require Tony's death.
** The Iron Man suit's infinity gauntlet that is holding the infinity stones. The moment Thanos attempts his second snap (seconds after having wrestled his hand free from Iron Man), it turns out that all the stones are gone... and have migrated over to ''Stark's'' gauntlet. Apparently he built a failsafe into it to prevent exactly this from happening.
* ChekhovsSkill: Tony and Nebula kill time while adrift in space by flicking a paper football back and forth. Incredibly, this comes into play during the Time Heist, when Tony needs to flick Ant-Man across a room and onto the HYDRA agent carrying the Tesseract in a briefcase.
* ChokeHolds: 2012 Steve Rogers puts present Steve Rogers in a chokehold, thinking that he is a disguised Loki. Present Steven Rogers manages to free himself by distracting his past self, saying that Bucky is still alive.
* ClimacticBattleResurrection: The victims of the Snap return to life for the final battle.
* ClipShow: Fitting for a finale. A subverted example occurs when the characters travel through time to collect the Infinity Stones. We get some clips, and some old scenes from new angles from ''The Avengers'', ''Thor: The Dark World'', and ''Guardians of the Galaxy''. But once the time-traveling present-day Avengers start altering events, there's plenty of new content, too.
* CloseEnoughTimeline: Steve returns to various timelines to return their Infinity Stones to make sure those realities more or less proceed along the same path as their own, rather than letting dark realities where TheBadGuyWins occur due to Captain Marvel never existing due to the Tesseract disappearing, Doctor Strange not being able to stop Dormammu due to lacking the Time Stone, Thor never stopping the Dark Elves due to lacking Mjölnir, and so on. However, Joe Russo confirmed in an [[https://www.businessinsider.de/avengers-endgame-directors-describe-making-of-the-movie-interview-2019-5?r=US&IR=T interview]] that Loki created an alternate timeline when he teleported away with the Tesseract in 2012, and that it would be "impossible for [Cap] to rectify the timeline unless he found Loki."
* ClothingDamage: Lampshaded when Professor Hulk says he's wearing shirts now. On travelling back to the past, he obligingly rips his own shirt off in order to pass as the Big Green Rage Monster.
* CollapsibleHelmet: Beyond the usual suspects from previous movies (Ant-Man, Iron Man, War Machine, Black Panther, Spider-Man, Star-Lord...), the quantum suits are made from nano-tech and can fully collapse. The helmet is the first to come off after a trip, even if the rest of the suit stays. This allows the protagonists to show their faces at almost all times, except when the helmets are an absolute necessity, i.e. during trips in the Quantum Realm.
* ColorMotif:
** In contrast to the neon-tinted teaser poster used for ''Infinity War'', the teaser poster for ''Endgame'' is a mix of purple and blue. This extends to some of the promotional material as well, as an abandoned New York City is seen bathed in a blue marine layer in the Big Game TV spot.
** The new [[https://www.comingsoon.net/movies/news/1053577-avenge-the-fallen-with-new-avengers-endgame-character-posters "character posters"]] are full color for the characters who survive but black and white for those who have died.
* CombinationAttack: Pepper, Shuri and the Wasp fire their weapons at Thanos to try to keep him at bay as Danvers cruises past him to the van.
* ComedicSociopathy: Thor threatens a young ''Fortnite'' player that he will come to the latter's place and tear off his arms, then taunting him further when he seemingly makes the child cry.
* ComfortFood: In addition to [[DrowningMySorrows drinking alcohol]], Thor is eating junk food.
* ComfortTheDying: Tony Stark, a.k.a. ComicBook/IronMan, is suffering from the CastFromHitPoints effect of the [[{{Superweapon}} Infinity Gauntlet]], which he has just used to utterly disintegrate a GalacticConqueror and his armies. In his final moments, his best friend, his protégé, and his wife are the ones to comfort him as he struggles to stay alive, but it's [[HopeSpot a battle Tony is losing]], and they all know it, as the toll of the Infinity Gauntlet had [[ChekhovsBoomerang already been established]] as nearly too much for [[TheBigGuy Hulk]] at peak condition, whereas Tony used it after a prolonged skirmish that left him running on fumes. With Tony's stubbornness serving only to prolong his pain, he finally passes, peacefully, when his wife tells him that they'll be okay thanks to his HeroicSacrifice.
* TheComicallySerious: Mantis, who proves she is capable of being silly and serious at the same time. This is especially obvious when she is seen charging into battle with M'Baku, Thor, and Captain America.
* ComicBookMoviesDontUseCodenames:
** Clint Barton is never called "Ronin" at any point in the movie.
** Likewise, while Pepper does finally don her armor, she's not called "Rescue" by anyone.
** Much like her debut solo, Carol Danvers is never called Captain Marvel.
* CompositeCharacter: Clint Barton. Much like his 616 incarnation, he takes the identity of Ronin following [[Film/CaptainAmericaCivilWar Civil]] [[ComicBook/CivilWar War]], and his change in attitude and costume following the tragic deaths of his family is reminiscent of Ultimate Hawkeye. However, whilst Ultimate Hawkeye became a DeathSeeker, MCU Hawkeye instead goes down the same route as ComicBook/ThePunisher, and starts ruthlessly murdering criminals who survived the Decimation. He comes very close to sacrificing himself for the Soul Stone to atone for his actions as Ronin, reminiscent of his Ultimate counterpart's DeathSeeker tendencies, but Black Widow performs the HeroicSuicide before he can.
* ConquerorFromTheFuture: Inverted. Thanos's past self from 2014 is accidentally warned that he will fulfill his goal of erasing half of the population but that the Avengers are traveling to the past in order to steal the Stones. Capturing the Nebula from the present and acquiring her Pym particles vial, Thanos, his warship the ''Sanctuary II'', and his army all come to the present to get all the Stones at once from the Avengers.
* ContinuityCavalcade: When the Avengers are gathering all the infos they have on the Infinity Stones' whereabouts over the years, they recall in turn some of the adventures that we've seen in the previous movies, each putting their own twist on their respective tales.
* ContinuityNod: Has its [[ContinuityNod/AvengersEndgame own page]].
* ContrivedCoincidence:
** Scott's escape from the Quantum Realm happens entirely by luck when a rat accidentally activates the portal. Let us give proper gravitas to this: this simple, infinitesimally unlikely action of a rat walking over a control panel leads to the invention of time travel, the ability to recover the Infinity Stones that Thanos wiped out of existence, and the resurrection of literally ''trillions'' of creatures eradicated by the Decimation.
** Bruce's belief that he could get the Time Stone from Doctor Strange in 2012 was completely wrong. Luckily for him, the Ancient One just happened to have the Time Stone in her possession while she was protecting the New York Sanctum during the Battle of New York in 2012.
* CoolShades: {{Deconstructed|Trope}}. Thor wears sunglasses in various scenes, even inside. But it rather highlights his failed attempts to put up a happy and relaxed appearance in order to conceal how depressed he really is, than actually make him look cool.
* CoolShip: The ''Benatar'' returns, as well as Thanos's ''[[MileLongShip Sanctuary II]]''.
* CoolVsAwesome:
** As with the first film, a time-displaced super-soldier, a nanite-powered tech genius-cum-playboy, a scientist with the body of a radioactive mutant, a CIA spook turned crime-fighting vigilante, a raccoon, a Norse God and a BlueSkinnedSpaceBabe go on a time-traveling quest to undo mass genocide. The super-soldier winds up fighting a past alternate universe self, and the raccoon accidentally angers the guards of Norse Mythology.
** The climax features a wizard teleporting in more wizards, an intergalactic alien militia, the remainders of Norse Mythology, a fighter pilot turned cosmic energy conduit, and reality-warped-back-to-life superheroes fighting alternate dimension counterparts of a Mutant alien overlord seeking to become a god and his army, made of space gorillas, giant bio-mechanical snakes, and cybernetically-enhanced mutant aliens.
* CrapsackWorld: Zigzagged. After Thanos wiped out half of all life, major governments quickly took measures to maintain order -- but it's clear that the combination of grief, loss of life, unsupported infrastructure and the resulting power vaccuum is eroding humanity steadily. Carol also discussed that other planets in the universe are losing stability while she's working to fix it.
* CrazyEnoughToWork: Steve and Natasha's plan has [[MillionToOneChance incredibly low odds of actually working]], but they're so determined to avoid letting that stop them because everyone will suffer even more if they fail. The plan is to attack Thanos where he's [[RetiredMonster retired]] and, to their surprise, Thanos is completely alone and ''much'' weaker due to [[DentedIron destroying the Infinity Stones having cost the majority of his strength]]. So ''of course'' the heroes' plan works much easier than it should.
-->'''Natasha:''' This is gonna work, Steve.\\
'''Steve:''' I know it is. 'Cause I don't know what I'm gonna do if it doesn't.
* CreativeClosingCredits: The film uses the style of end credits from ''Film/StarTrekVITheUndiscoveredCountry'', by showing the signatures of the actors who played the original Avengers.
* CreatorCameo:
** Co-director Joe Russo plays a man in a support group for people losing love ones with Captain America. He is the first character openly on the LGBTQ spectrum portrayed in an MCU film. Thanos creator Jim Starlin is also a member of the support group.
** In Creator/StanLee's last cameo, he plays a hippie who drives past the entrance of Camp Lehigh, jeering at them. Lee was de-aged for this scene to look as he did in the [=1970s=], alongside a completely CGI recreation of his wife, Joan Lee, as she appeared at that time. This also marks the second time that Joan Lee had a cameo in a Marvel film after ''Film/XMenApocalypse''.
** When Scott is looking at the memorials for the people who vanished, many names listed are of people who worked on one or more Marvel films, including VFX editor Emily Denker, CG artist Geoff Diamond, animator Marco La Torre, and digital asset coordinator Susana Lou.
** Screenwriter and producer Christopher Markus appears briefly at the start of the 1970 sequence as one of the men entering the S.H.I.E.L.D. bunker.
* CringeComedy:
** When meeting up with Professor Hulk at a diner, a group of kids come up and ask for a photograph with him, to which he obliges, but then Lang asks the kids if they want a photo with him too, but since he's out of costume, they don't realize he's someone special, and as he tries to explain himself, Prof. Hulk at the same time is trying to cover for him, with Ant-Man just wanting the suggestion to be dropped, and Hulk trying to encourage the kids.
** When Tony accidentally teaches his daughter how to swear, we are "treated" to the hilariously horrifying sight of a tiny and adorable little girl cheerfully giggling "shit" (twice!) before Daddy Foul-Mouth hurriedly tries to teach her "You can't say that! That's mommy's word!"
** The hilariously shocking reveal that Thor has become [[{{Hikikomori}} an overweight alcoholic video-game junkie who spends all day indoors]] in ''only'' his underpants would be right at home in an Creator/AdamSandler gross-out comedy. You'll hate yourself for laughing ''with'' a grown-ass 1500-year-old God yelling at a 10-year-old Internet {{Troll}} over Playstation-Chat, threatening to "rip his arms off and shove them up his butt"... but you'll laugh anyways.
** When Thor tries to enlighten the other Avengers on the Aether/Reality Stone, he ends up rambling about Jane, Odin, and the nature of life. Eventually, Tony has to interrupt him and save him from himself as he babbles aimlessly.
** Overlapping with BlackComedy, Rhodes suggesting that the Avengers should just use the time machine to go back to when Thanos was a baby and strangle him with a garrote, pantomimed and complete with choking noises. Professor Hulk is naturally ''horrified'' by this proposal.
--->'''Rhodey:''' It's ''Thanos''.
** InUniverse literal example: Captain Rogers, Lang, Stark and Banner just ''have'' to bump into Hulk the way he used to be back in 2012 in their time-travel quest for the New York Infinity Stones. The first three men look on bug-eyed and stupefied as the Hulk violently jumps up-and-down on a car like a broken trampoline screaming like a five-year-old ''after'' using it to smash a Chitauri to death, while the now peace-loving Doctor Banner covers his face and cringes in humiliation.
* CryCute:
** Natasha is weeping while eating her peanut butter sandwich.
** When Thor is caught by Frigga, his mother, during his quest for the Reality stone travelling back in time, he thinks she will be ashamed of him because he is now an overweight alcoholic shut in. Instead, she assures him she still loves him, and encourages him to pick himself up and be the best person he can be, instead what others expect him to. This causes the former god of thunder to adorably weep like a little boy as his mom lovingly hugs him.
* CueTheSun: Although there's still some daylight when Thanos's ship arrives and the FinalBattle begins, the destruction of the landscape and ''Sanctuary II'' itself cover the land in dusty, thick gloom. Then, as Captain America [[DarkestHour prepares to make his final stand]], a luminous magical portal opens up behind him, revealing the noon sunshine of Wakanda. It's so bright that, when Okoye, Shuri, and T'Challa step out, it seems for all the world that they are stepping ''[[InvertedTrope out]]'' [[GoIntoTheLight of pure light]]. Then the rest of TheCavalry steps out from their own [[RaysFromHeaven sunlight-filled portals]].
* CurbStompBattle:
** The surviving Avengers and their allies manage to locate Thanos in his farm within the first twenty minutes of the film. By then he's already retired to a quiet life and has destroyed the Infinity Stones, which left him a fraction of his original strength. Captain Marvel, Bruce in the Hulkbuster, War Machine, and Thor quickly make short work of him. Justified since Thanos destroyed the Stones, he doesn't have his army, and [[DeathSeeker he wants to die anyways after murdering his daughter and half the universe]].
** The Hulk makes a move to attack the Ancient One to get the Time Stone. She knocks Banner right out of the Hulk's body with her astral strike.
** Past Thanos hands these out like candy, stomping almost every hero that tries to attack him. The only ones he couldn't stomp are an enraged Scarlet Witch, who instead matches and gradually overpowers him herself (to the point the last leg of their fight is practically a Curb-Stomp in its own right), and a fully-powered up Captain Marvel, which he needed the Power Stone to take out.
** Corvus Glaive gets unceremoniously ImpaledWithExtremePrejudice by Okoye. She barely even breaks stride in her forward charge.
** Giant-Man easily punches Leviathans out of the sky, ''and'' {{Goomba Stomp}}s Cull Obsidian with little effort; also he doesn't even seem winded as he did in ''Civil War'' and ''Ant-Man and the Wasp''.
* CurbStompCushion: While the past Thanos overwhelms the Avengers and if not for a last second sleight-of-hand would have won, they manage to get a few good hits in:
** Cap with the power of Mjölnir and his own skill in using his shield treats Thanos like a ragdoll, until he figures out his tricks and breaks Cap's shield in the process.
** Wanda is extremely close to killing Thanos outright, breaking his sword and crushing him in his own armor, but him raining fire on the battlefield takes her out of the fight.
** Finally, Carol manages to fight Thanos to a stalemate, outright {{No Sell}}s his headbutt, and nearly breaks his gauntlet hand, before he knocks her out with the raw power of the Power Stone.
* CutTheSafetyRope: Clint and Natasha's fight over [[MoreExpendableThanYou who gets to die so the other may get the Soul Stone]] ends this way: Clint is saved from falling using Natasha's safety rope, with Natasha holding only one of his hands. [[HeroicSuicide And then she lets go of his hand.]]

!!!''Film/AvengersEndgame'' provides examples of the following tropes:
[[foldercontrol]]
[[folder:#]]
* EleventhHourRanger:
** Captain Marvel. After being absent from Earth's events throughout the MCU timeline, she returns to assist the other survivors of Thanos's culling of half of all life in the universe. Then she leaves again when Natasha dispatches several Avengers on missions in space, only to show back up for the final battle.
** Hawkeye is the last to join the group, having been absent from ''Avengers: Infinity War'' due to his house arrest after ''Captain America: Civil War'' and taking up vigilantism as Ronin after the time skip.
** Ant-Man, Rocket, Nebula, and Captain Marvel are now officially members of the Avengers.
** Pretty much everyone resurrected from the first film in the climatic battle.
** The Wasp and Pepper Potts (in her own suit of Iron Man armor) also join the battle.
** In a blink-and-you'll-miss-it moment, you may well spot Howard the Duck brandishing a gun with the Ravagers as they head into battle.
* TwentyMinutesIntoTheFuture: The bulk of the movie takes place five years after ''Infinity War'', which was set in 2018, so therefore set in 2023.
* TheSeventies: Steve and Tony travel to 1970 to get the Tesseract after the previous attempt in 2012 failed spectacularly. The opening scene shows a carful of hippies (among them [[CreatorCameo Stan Lee]]) driving by the entrance of Camp Lehigh and jeering, and later, Howard asks if Tony is a beatnik, due to his facial hair.
[[/folder]]
[[folder:A]]
* AbdicateTheThrone: Thor declares Valkyrie the ruler of New Asgard, after commenting that for the first time in a thousand years, he won't have to be who he's supposed to be, while acknowledging that Valkyrie was essentially ruling New Asgard already while he spent the last five years doing nothing but drinking, eating junk food, and playing video games.
* AbortedArc: The Sokovia Accords are totally unmentioned throughout the movie, but Captain America and Black Widow are no longer considered enemies to the public, Rhodey's court martial seems to have never happened, and Hulk is able to operate in public to the point where ''he's able to pose for selfies with kids''. Presumably, the issue has more or less been dropped in the wake of the larger issues that the Earth is facing, or otherwise rewritten in the five year gap.
* AbsenteeActor:
** Emily [=VanCamp's=] Sharon Carter is nowhere to be seen at Tony Stark's funeral after the snap is undone, nor is she mentioned.
** Martin Freeman's Everett Ross, previously seen in 2018's ''Black Panther'', is also absent.
** Lupita Nyong'o (Nakia) did not appear in the film.
* AbsurdlySharpBlade:
** Stormbreaker, which not only decapitates a weakened post-snap Thanos with a single strike, but later in the climax starts to cleanly dig into Thor's armor when Past Thanos is pushing it into his chest, while Thor is also trying to push it away.
** Thanos's double-bladed sword, which is sharp enough to take chunks off of Cap's famously "unbreakable" vibranium shield.
** Clint's sword is not as impressive as the other two, but it is nonetheless shown to be able to slice an Outrider in two.
** Valkyrie's lance is capable of slicing into a Leviathan's armor plating like a hot knife through butter. This is the armor that Jarvis once said "we will lose power before we break through that shell."
* AchillesInHisTent: Of all the Avengers, Thor takes the events of the Snap the hardest. Five years later, he's become an [[FormerlyFit overweight]], [[DrowningMySorrows alcoholic]] [[{{Hikikomori}} shut-in]] who spends his days drinking beer and hanging out with Korg and Miek as they play ''VideoGame/{{Fortnite}}''. Rocket and Hulk coax him into coming out of retirement, but he doesn't start to get his groove back until after getting a pep-talk from his mother while time-traveling to Asgard in 2013.
* AdaptationExpansion: The movie actually shows the fallout of Thanos's victory following the Snap. In the ''Infinity Gauntlet'' storyline, the Snap occurred within the first few pages and the counterassault (and subsequent ResetButton) came within 24 hours, too short a time-frame to display any real consequences that such an event would have on the population.
* AdaptationalVillainy: In the comics, after the events of ''ComicBook/TheInfinityGauntlet'', Thanos comes to realize he's not worthy of wielding the god-like powers of the Infinity Gems, so he eventually becomes an AntiVillain who often fights on the side of the heroes. Here, there is no such HeelFaceTurn: the older version of Thanos remains convinced his actions were justified, while the 2014 version is even more omnicidal than in the previous films.
* AdultFear:
** Clint gets to live his worst nightmare when, in the middle of a lighthearted picnic, he only turns his head a moment and sees his family has disappeared without warning. He is then overwhelmed by the confusion and distress of having lost his wife and children without having been able to protect them, or even knowing what happened.
** Scott Lang gets a moment of anguish when he worriedly looks at the memorials to the fallen in the hopes his daughter Cassie is not among the victims. She's not, but he gets another variation of this trope on seeing '''his''' name: his daughter thinks he's been dead for five years, and he's missed five years of her childhood.
** PlayedForLaughs when Tony realizes his daughter heard him swearing and is up late past her bedtime. The idea that your kid can start repeating curse words and you have to explain yourself or bribe her with popsicles.
* AdvertisedExtra:
** Captain Marvel was heavily featured in the promotional material for the film, especially after [[Film/CaptainMarvel2019 her own movie]] proved to be a huge hit at the box office. Despite this, she disappears after the fight with Thanos in the first act, and is absent from the film until the final battle. This is pretty much a repeat of what happened with Black Panther in the marketing for ''Infinity War'', right down to the ads overselling the size of his role due to the success of his solo movie. {{Justified|Trope}} due to her [[StoryBreakerPower abilities matching if not exceeding those of Thanos]] (without the help of a stone); and when she ''does'' appear in the final battle, she proves to be a difference-maker, destroying Thanos' ship and outclassing the Mad Titan himself. She also had other planets to mind that didn't have heroes of their own.
** Okoye is also featured prominently in the American theatrical poster, as is Valkyrie in some of the international ones. Like Captain Marvel, they don't get to do much until the final fight with Thanos's forces.
** Wong is shown in one of the "Avenge the Fallen" posters in color but much like Captain Marvel, Okoye, and Valkyrie, doesn't appear until the Avengers really need them.
* AnAesop:
** Thor learns that the measure of a true hero isn't living up to the expectations of others, but by doing your best being a decent person that is true to yourself.
** Also, after [[MyGreatestFailure loss]] comes [[MyGreatestSecondChance second chances]]: whether it be a chance to take back what you lost, or build something new out of what you have left. Ultimately, the Avengers realize this and use this to their advantage (such as when Steve and Tony, after losing their chance to gain the Tesseract, stay determined and resourceful and find another way) which ultimately ensures their victory; while Thanos, who is given a second chance to achieve a permanent victory in his world (by learning from the Avengers' actions and doubling-down on his plan to erase 100% of the universe rather than just 50%), instead goes for the much more brash and careless option and ultimately ensures his own demise.
** Being a hero requires being willing to make [[HeroicSacrifice the ultimate sacrifice]]. The Avengers spend most of ''Infinity War'' trying to find a way to extract the mind stone from Vision without killing him because to quote Steve, "they don't trade lives". They run out of time and ultimately Wanda has to do what they've been putting off the whole movie. However Thanos is able to use the time stone to rewind his destruction and complete the gauntlet, leading to the snap. This time around no one hestitates to lay down a life to stop Thanos. Clint and Natasha are both willing to throw themselves off the cliff to get the soul stone, Bruce wears the gauntlet to snap everyone back despite not knowing exactly what it will do to him, and then Tony also uses the guantlet knowing it will kill him.
* AffirmativeActionLegacy: Just like his comics counterpart, Steve retires and passes the shield to Sam Wilson.
* AfterTheEnd: The story shows how the world has been dealing with the loss of half of all life in the universe in the [[TimeSkip five years]] since the prior movie, which [[DarkestHour isn't great]] despite what Thanos may think. People are traumatized, cities are quiet and empty-feeling, and no one can really bring themselves to move on or even do anything. Steve has actually started a support group for people in order to try and get them to move on with life and continue.
* AlasPoorVillain:
** The prime Thanos, while he succeeded in wiping out half the universe, believed he was doing it for a very noble cause. So it is still sad to see him overpowered by the Avengers and killed by Thor. The former after being severely injured by using the stones to destroy the stones and the latter after he tells Nebula that he's beginning to think he treated her too harshly.
** Once Thanos and his forces are now on the receiving end of the snap, you can just see it in his eyes that he knows that he's doomed. He rests in the desolate Avengers HQ, looking up with an expression of pure agony as he slowly lowers his head; eyes closing, and body sulking down to the ground. No [[VillainousBreakdown mental breakdown]]. No [[FamousLastWords last words]]. No [[SkywardScream screaming]]. No [[HeelRealization admission of wrongdoing]]. Not even an [[BigNo expression]] [[ThisCannotBe of]] [[LittleNo disbelief]]. Just utter silence, despair and surrender as he awaits the [[ArcWords inevitable]].
** As they turn to dust, Ebony Maw reaches out to Thanos in confusion and terror, and Proxima cradles the dead Corvus as she dies (he was ran through by Okoye earlier).
* AlienArtsAreAppreciated: Korg and Miek are playing ''VideoGame/{{Fortnite}}'' when Rocket and Professor Hulk find them and Thor in New Asgard.
* AlienInvasion:
** The Chitauri invasion of New York City during ''The Avengers'' is revisited, although most of the action takes place after the invasion has been dealt with.
** 2014 Thanos makes his way to the Earth of the prime timeline, along with his whole army. Only this time the Avengers and their allies are all able to gather at the same place for a welcome committee.
* AllDeathsFinal: At least in the case of the Soul Stone and who is sacrificed to retrieve it. They can't be brought back to life, even with all six Stones. Likewise, a being who uses all six Stones but isn't strong enough will also die and can't be brought back. It's also implied that only the people directly killed by the Snap were brought back and not, say, the people killed when millions of cars on the road suddenly lost their drivers, or anyone who was killed during Thanos's quest for the Stones.
* AllForNothing: By the end of the first act, the Avengers find and kill Thanos, but even ''before'' Thor decapitates him, they realize it's all for naught since Thanos already destroyed the Infinity Stones beforehand, robbing them of a means to undo the damage he has done, and reducing them to just trying to pick up the pieces, at least until Scott shows up with an idea.
* AllThereInTheManual:
** The Russo brothers answered a few hanging questions the movie made in a [[https://bgr.com/2019/04/30/avengers-endgame-ending-russo-brothers-on-captain-america-iron-man/ BGR article]]. One of the biggest {{Plot Hole}}s was just how did Past-Thanos bring his entire ship and army into the future? There's literally no questioning of how it happened. The banging sound in the Marvel logo at the end of the credits was the Russo's way of saying goodbye to Iron Man.
--->'''Q:''' How did Thanos bring his army to the future?\\
'''A:''' There is a guy called Maw in his army, he was [[AWizardDidIt a great wizard]]. Thanos himself was a brilliant genius as well. Those two easily reverse-engineered and mass-produced Pym Particles.
** The ages of Scott Lang's age-altered selves are given in the credits as 12, 93, and [[TheLastOfTheseIsNotLikeTheOthers baby]].
** Thanos's double-bladed sword is described as made of uru metal, like Mjölnir and Stormbreaker, explaining why it can cleave Cap's shield.
* AllYourBaseAreBelongToUs: The finale begins when Thanos from 2014 arrives at the Avengers Headquarters and the resulting battle utterly obliterates and destroys the compound.
* AlmostOutOfOxygen: Tony Stark and Nebula have run out of food and water and are about to run out of oxygen on their way back to Earth on the ''Benatar'', the Guardians' space ship. [[BigDamnHeroes Cue]] [[Film/CaptainMarvel2019 Carol Danvers]].
* AlternatePersonalityPunishment: In the aftermath of Thanos ending half of all life in existence, the heroes manage to assemble what's left of the team and beat the crap out of Thanos... who has taken up the CallToAgriculture and barely puts up any resistance. He doesn't even have the Infinity Stones anymore, having used their own power to destroy them, greatly weakening himself in the process. The Avengers kill him anyway, but it's obvious they feel no satisfaction or justice from doing so. Fortunately, they go back in time to retrieve the stones to undo the damage and are followed by pre-snap Thanos, resulting in a Thanos who is very much satisfying to kill, even if he technically hadn't killed half of all life (it helps that having seen the results of only killing half of it, he decides to kill the ''entire'' Universe and start over so no one will remember his role).
* AlternateSelf: When travelling in time, some Avengers meet past versions of themselves. The "alternate" part is in full motion when each of these timelines is changed by them.
* AlternateTimeline:
** Changing any event in the past creates one of these, while the traveler's own past remains untouched. As such, the six timelines that the Avengers create include:
*** '''1948''': (3 years after ''Film/CaptainAmericaTheFirstAvenger'') The main timeline version of Steve goes here to spend his life with another timeline's Peggy Carter after World War II, before returning to his original timeline after her (presumed) death in 2016. As such, Steve is an old man when he returns. This one is a weird one because the writers and directors disagree on whether this was ''actually'' an alternate timeline, or whether it was part of the original timeline all along, with Steve actually [[CanonCharacterAllAlong being Peggy's mystery husband who was discussed in]] ''Film/CaptainAmericaTheWinterSoldier''. As the year Steve travels back to is 1948 and not 1945, this would still give the ''Series/AgentCarter'' series plenty of time to take place.
*** '''1970''': After Hank Pym is distracted by a fake emergency call, four vials of the Pym particle go missing from his lab at the Camp Lehigh S.H.I.E.L.D. facility (granted they're only taken and used by Steve and Tony to get back to the present, but Hank and S.H.I.E.L.D. have no way of knowing this). Howard Stark also has a conversation with one "Howard Potts" (his future son Tony from the main timeline), and Captain America sees photographs on the desk inside the office of S.H.I.E.L.D.'s director Peggy Carter that make it clear she never forgot him.
*** '''2012''': (right after the climax of ''Film/{{The Avengers|2012}}'') Loki escapes custody with the Tesseract immediately after the Battle of New York and is never imprisoned on Asgard, and HYDRA agents believe Captain America is on their side (but 2012 Steve is unaware of this). The Ancient One learns of Doctor Strange's plan to stop Thanos years later, and Captain America is also made aware of Bucky's survival (although how much he believe this information is up for debate).
*** '''2013''': (during ''Film/ThorTheDarkWorld'') The Asgardian army chases a "rabbit" (Rocket) after it extracts the Aether from Jane Foster, while Frigga is made aware of a future Thor from a different timeline. Mjölnir is borrowed from this timeline. And similar to the missing baseball glove from the Barton farmhouse, while minor, the large can of beer that Thor leaves behind in Asgard can potentially trigger a (hopefully minor) comedic butterfly-effect that will nevertheless still change the future.
*** '''2014''': (right before ''Film/GuardiansOfTheGalaxy'') Thanos and his forces (aside from Ronan and Korath) completely disappear from this timeline and are killed along with that timeline's Nebula in the main timeline, while the Gamora of this timeline lives on in the prime timeline, replacing her dead original future self. With this timeline's version of Gamora now in the main one, the Guardians of this timeline likely never form, especially since Peter Quill was knocked out before he could get the Power Stone (potentially giving the Kree time to get it after Cap puts it back).
*** '''2018''': [[TheLastOfTheseIsNotLikeTheOthers A baseball glove disappears from the Barton household.]] This might not have any significant effect on world events, but butterfly effect, so you never really know.
** This is also why Steve goes back to the various timelines to return their Infinity Stones and Mjölnir: without them, the bad guys would never be stopped in that timeline's version of ''Film/{{Doctor Strange|2016}}'' (Time), ''Film/{{Captain Marvel|2019}}'' (Space), ''Film/GuardiansOfTheGalaxy'' (Power), ''Film/ThorTheDarkWorld'' (Mjölnir), and so on. While there are likely some major and irrevocable changes, this will mitigate some of them a great deal.
* AlternateUniverse: This is the primary difference between scientific time travel (via the Quantum Realm) and magical time travel (as has been shown with the Time Stone). As explained by Professor Hulk and later the Ancient One, quantum time travel creates a new alternate reality that diverges at the point you arrive, so that everything that follows has no effect on the original timeline.
* AmazonBrigade: During the final battle, when the Avengers are relaying the Infinity Gauntlet towards the Quantum Tunnel, Spider-Man passes it off to Captain Marvel, who gets an escort from every single active female Avenger or ally: Okoye, Shuri, Scarlet Witch, Valkyrie, Gamora, Nebula, Mantis, the Wasp, and Pepper Potts in her Rescue suit.
* AmbiguousSituation: After Steve returns Mjölnir and the Infinity Stones, and goes to live in the past with Peggy Carter, did he create an AlternateTimeline, or was he part of the ''original'' timeline all along? Since the year Steve travels back to is 1948, this allows plenty of time for the ''Series/AgentCarter'' series to take place before Steve comes into the picture. The writers have suggested that Steve was Peggy's [[CanonCharacterAllAlong mystery husband all along]], but the directors have stated that Steve simply went to live in an alternate reality, leaving this situation up in the air.
* AmicableExes: After briefly touching on their quasi-relationship in ''Film/AvengersInfinityWar'', Natasha and Bruce have reached a version of this following the time skip.
* AndStarring: Theatrical posters only have the singular "With Creator/JoshBrolin as ComicBook/{{Thanos}}." The end credits to the film actually has [[UpToEleven enough people being credited this way]] that the list is as long as the cast listing for other films in the MCU: "Featuring Creator/VinDiesel as Groot, Creator/BradleyCooper as Rocket, with Creator/GwynethPaltrow, with Creator/RobertRedford, with Josh Brolin as Thanos, with Creator/ChrisPratt, and Creator/SamuelLJackson as Nick Fury." And ''then'' it concludes with the original six, including the actors' signatures along with the usual titles.
* AndTheAdventureContinues:
** While most of the Avengers' arcs are tied up with death or a happy retirement, Thor joins the Guardians of the Galaxy (at least temporarily) to do a cosmic version of WalkingTheEarth.
** Steve gives Sam the shield and deems him the new Captain America.
* AnimalMotifs: The ''Benatar'' resembles a swallow in the contre-jour shot where it is drifting around in space. Being a monogamous migrating bird, swallows are a symbol for loyalty, hope, and the safe return home after a long journey. Thanks to Captain Marvel, Tony and Nebula make it back home in one piece.
* AnswerCut:
** When Scott Lang discusses his plan with Cap and Black Widow, he seems to get the idea that they don't know how to help him. He asks, "So who do we go to?" Cut to a shot of Tony's new home as he walks out to look for Morgan.
** After Stark rejects them, Cap comments, "We're going to need a really big brain." Doubtfully, Scott asks, "Bigger than [Stark]'s?" Cut to a shot of Banner/Hulk eating his food, angled to show off his huge head first.
** When Rhodey and Nebula arrive on Morag, Nebula warns Rhodey that several people (including 2014 her) are also searching for the Power Stone at the same time. Rhodey asks, "Wait, where are you right now?" Cut to 2014 Nebula trying to fight aliens.
** Thousands of people arrive to the Avengers HQ battlefield via sorcerers' portals. Strange asks Wong, "Is that everyone?", to which Wong responds, "You wanted ''more''?" Then Giant-Man bursts out of the rubble with Rocket, Hulk, and Rhodey, and they all get in position to fight.
* AntiRoleModel: Howard Stark admits to "Howard Potts" (i.e. time-traveling Tony) that he is dreading the possibility of his son turning out like him, and hopes he becomes better than him.
* TheApocalypseBringsOutTheBestInPeople:
** Downplayed. The film doesn't call attention to this trope, but it seems to be in effect. Despite the elimination of half of all life in the universe, human civilization continues without collapsing into dystopia. This applies to some specific heroes in particular. Banner despite being a hero before the tragedy ultimately takes his defeats as a learning opportunity and reconciles his Banner/Hulk sides to become the best version of himself. Nebula goes on to fully complete her HeelFaceTurn by working with the heroes to rebuild and thwart the event.
** It's also subverted. While civilization overall seems to have managed to muddle through, people are still traumatized over five years later. People just going out on a date end up crying during the date, but this is considered so normal that they still schedule another one. From hints Carol gives during her briefing with Natasha, other planets aren't doing much better. The inability to move on is so bad that when 2014 Thanos shows up, he decides that the only way to get things moving again is to destroy ''everything'', and start the universe from scratch.
* ApocalypticLog: Tony Stark records a message on one of his helmets while drifting out in space. With his food and water gone, and his oxygen about to run out, he intends for it to be his final message.
-->'''Tony:''' Hey, Miss Potts. If you find this recording... don't feel bad about this.
* ArbitrarySkepticism: Discussed, when the Avengers talk about Scott's time travel idea which Nat really takes seriously, much to Scott's own amazement. Natasha points out she gets "emails from a raccoon" -- time travel wouldn't be hard for her to get behind.
* ArcWords:
** "Whatever it takes" for the surviving Avengers determined to bring back the people they lost to the Decimation. These are the words that Black Widow and Hawkeye repeat when they realize that the Soul Stone demands a sacrifice from one of them.
** "Move on" in the early part of the movie, as the characters try to adapt to the effects of the Decimation, and that they had no way of undoing it, at first. It's also relevant in how Thanos expresses disappointment at the heroes for trying to undo his future self's work.
** "I am inevitable" from Thanos. The line is first used by the retired Thanos defiantly saying that his work is irreversible to the Avengers. It is later repeated when Past Thanos watches the recording of his future death. And it is the last thing that Past Thanos says before realizing that Iron Man has the Infinity Stones and uses them to kill him and his army, thereby averting the "inevitable" altogether.
** "I am Iron Man": Going all the way back to the first Iron Man movie and the start of the MCU; Tony repeats it at the end of the third Iron Man movie, and repeats it one last time here, before he uses the Infinity Stones against Thanos and his army.
* AnArmAndALeg: When the remaining Avengers get the drop on Thanos on the Garden planet, the first thing done after immobilizing him is Thor cutting his gauntlet arm with Stormbreaker. The fact that Thanos never removed it despite the Infinity Gauntlet no longer sporting the Stones (and thus being now useless) hints that it had fused with his arm after its last use.
* ArtisticLicenseMartialArts: When Hawkeye's daughter is practicing archery with him she raises her elbow upwards when pulling back the bowstring instead of keeping it horizontal. Despite that she hits the target dead centre and Hawkeye compliments her technique.
* ArtisticLicensePhysics: At the beginning of the first act, the ''Benatar'' is out of fuel in the middle of outer space, completely motionless. While this would impact life support, the ship should still retain forward momentum, instead of being "dead in the water". Though there is little meaningful difference between being motionless as such and simply not moving quickly enough for the motion to be apparent, given the vastness of the void of space.
* AscendedExtra:
** Hawkeye has always been a supporting character, and of the original six Avengers, he's gotten the least time to shine out of anyone. Here he gets his own ''major'' plotline revolving around his relationship with Black Widow, and the scene of [[AdultFear his family disappearing]] while he's on a picnic with them is the [[DownerBeginning very first scene]] of the movie -- before even the Marvel logo!
** Ant-Man, when looked at from a broader scale. He is considered one of the main stars in the movie, and this may be a surprise as he wasn't introduced until the end of Phase 2. Both of his movies, while not slouches at the box-office overall, trail behind the other MCU stars and are relatively self-contained, while his role in ''Civil War'' was rather minor, not to mention that he sat out of ''Infinity War''. Here, while the movie also emphasizes the six founding Avengers, Ant-Man's involvement is ''very'' important to defeating Thanos. This is not unlike Doctor Strange's role in ''Infinity War''.
** Nebula. She started out as a secondary villain -- basically just there so Gamora had somebody to fight in the third act. Now she's one of the (many) central characters in the biggest film event in history, and half the plot hinges on her.
* AssShove: Thor's solution for [=NoobMaster69=]'s trolling is threatening to do this to him with his own arms.
* AssholeVictim: Thanos at the end of the first act may have just become a peaceful farmer in his retirement from being an omnicidal warlord, but you'll still likely not shed any tears over him when the Avengers ambush him, cut off his arm, and eventually decapitate him. Clint's crusade against the criminal underworld also applies, as he butchers any cartel, yakuza thug, or other criminal scumbag he comes across.
* AstralProjection: When Professor Hulk gets impatient with the Ancient One, she forces Banner out of the Hulk's body in astral form. Banner then converses with her while the Hulk is left sleeping on a chair.
* AudibleSharpness: Stormbreaker makes its usual sounds flying through the air, cutting through things...and opening Thor's beer.
* AudienceSurrogate: Scott acts as one throughout the film, being the guy completely shocked at how much the heroes and their world have changed since he last saw them, and desperate to get back what has been taken from them. Scott also bases his understanding of TimeTravel on popular movies rather than an understanding of the actual science that would be involved. Tony and Bruce use this to distinguish between more science-based TimeTravelTropes and those less based on (currently understood) science.
* AuraVision: Thor tries to trick Frigga into thinking that he's the Thor from her timeline, and fails miserably.
-->'''Frigga:''' I was raised by ''witches'', boy. I see with more than eyes, you know that.
* AvengersAssemble: Right before the final battle, Doctor Strange and a bunch of other sorcerers warp superheroes and various other warriors to the remains of the Avengers compound in order to fight off Thanos's invasion. The words are finally spoken by Cap, although he says it ''after'' everyone's assembled... which is actually true to the source material.

[[folder:B]]
* BackForTheFinale:
** Lots of characters return for the final battle, including all the heroes who died in the original Snap. This even extends to {{Mooks}} on both sides; Thanos brings Outriders from ''Film/AvengersInfinityWar'', Chitauri and Leviathans from ''Film/{{The Avengers|2012}}'', and Sakaarans from ''Film/GuardiansOfTheGalaxy''. The Avengers get Sorcerers from ''Film/DoctorStrange2016'', Asgardians from [[Film/{{Thor}} the]] ''[[Film/ThorTheDarkWorld Thor]]'' [[Film/ThorRagnarok films]], Ravagers ([[MyFriendsAndZoidberg and Howard the Duck]]) from ''Film/GuardiansOfTheGalaxyVol2'', and Wakandan warriors from ''Film/BlackPanther2018''.
** Also, many of those who died in previous films (or haven't been seen since) are seen again as the Avengers travel through time. In New York: Loki, Brock Rumlow, Agent Sitwell, Alexander Pierce, and the Ancient One. On Asgard: Frigga, Jane, and Loki again. On Lehigh Base: A younger Hank Pym, Howard Stark, and Edwin Jarvis. On Vormir: Red Skull. And an older version of Harley from ''Film/IronMan3'' appears at Tony's funeral.
** For the very first time, a character from the Marvel TV shows gets to migrate to the movies, when [[Series/AgentCarter Edwin Jarvis]] is shown chauffeuring Howard Stark at the Lehigh military base.
* BackFromTheDead:
** The quantum time travel device allows the Children of Thanos, all of whom were killed in ''Infinity War'', to return for the last battle with the Avengers. The same goes for Thanos, who is killed by Thor in the first act of the film, but is eventually replaced with a slightly younger counterpart from earlier in the timeline.
** In the finale, Hulk un-snaps everyone dusted in ''Infinity War'' back into existence, eventually leading to a final confrontation between the heroes of Earth and Thanos's forces.
** The quantum time travel device also brings back Gamora, as the Gamora of 2014 hadn't been killed by Thanos. However, since this is a Gamora from before she ever met Star-Lord, this causes a relationship reset.
* BackToBackBadasses: Tony and Pepper guard each other in true BattleCouple fashion during final battle so neither is snuck up on.
* BackToTheEarlyInstallment: Thanks to Thanos destroying the Infinity Stones after his infamous snap, the Avengers have to use time travel to go to the past where they still existed so they can undo the snap. To find them they go to the events of ''Film/{{The Avengers|2012}}'', ''Film/ThorTheDarkWorld'', and ''Film/GuardiansOfTheGalaxy''. We get to see them arrive during the 2012 Avengers' famous pose, and right at the start of Peter Quill going after the Power Stone.
* BadassArmy: The Avengers are joined at the climax of the film by ''practically every single heroic force'' introduced in the MCU, from the Guardians of the Galaxy, the Masters of the Mystic Arts, the Asgardians, the Ravagers, and the Wakandans to form one hell of an army of {{Superhero}}es, [[KungFuWizard Kung-Fu Wizards]], [[Myth/NorseMythology Norse gods]], SpacePirates, [[{{Afrofuturism}} Afrofuturist]] warriors, and [[TheLastOfTheseIsNotLikeTheOthers a gun-toting, talking]] [[Comicbook/HowardTheDuck duck in a suit]]. They clash with Thanos's own forces, consisting of the Chitauri, the Sakaarans and the Outriders.
* BadassBoast:
** In the finale, Wanda lands in front of Thanos with vengeance written on her face.
--->'''Wanda:''' You took.... ''everything'' from me.\\
'''Thanos:''' I don't even know who you are.\\
'''Wanda:''' ''You will.''
** Few boasts can hold a candle to Tony Stark’s FamousLastWords:
--->'''Thanos:''' I am inevitable.\\
'''Tony:''' '' And I... am... Iron Man.'' ''[snaps]''
* BadassFingersnap:
** Once the Avengers collect the Infinity Stones, Bruce does it to bring back everyone turned to dust.
** Once Thanos has the gauntlet and has taken out everyone trying to stop him, he snaps to fulfill his new plan, [[SubvertedTrope nothing happens]]. It turns out Tony took the stones, and does one to disintegrate Thanos and his forces.
* BadBadActing: When part of the Avengers time-travel to 2012 during the Battle of New York, they witness the Hulk throwing a fit. Professor Hulk is told to act like the Hulk to blend in, and he grumbles that it's "gratuitous", but he'll do it. He goes over to some vehicles and gives them a few unmotivated punches while lazily saying "roaaar".
* BadVibrations: Steve's bathroom mirror vibrates when Captain Marvel returns the ''Benatar'' to the Avengers Headquarters.
* BaitAndSwitch: Cap is once again [[Film/CaptainAmericaTheWinterSoldier inside an elevator full of HYDRA infiltrators within S.H.I.E.L.D.]] who refuse to give him Loki's scepter and get suspicious of his insistence. Looks like we'll get another elevator fight, right? Nope, Steve instead [[TrustPassword whispers "Hail HYDRA" in Sitwell's ear]]. Suddenly they all think he's a fellow sleeper agent and hand him the case, no questions asked.
* {{Bathos}}: At the dramatic climax of the epic three-hour-long extravaganza, 2014 Thanos reclaims the Infinity Gauntlet, dramatically declares "''I am inevitable''", and [[TheBadGuyWins snaps his fingers]] ''[[AllForNothing again]]'', and...nothing happens. No flash of light, no dramatic explosion of energy, just a tiny, [[FailedAttemptAtDrama hilariously anticlimactic]] ''clink'' of metal. [[MusicalisInterruptus Even the music cuts out]] as soon as he snaps his fingers. And then the arrogant smile [[OhCrap vanishes from Thanos's face]] as he looks over and sees that ''Tony Stark has the Infinity Stones.''
* BattleCouple:
** Couple Tony Stark and Pepper Potts suit up and blast through Thanos's forces. This includes a BackToBackBadass shot.
** Scott and Hope get such a moment, the Wasp helping Ant-Man move through the battlefield by flying.
* BattleCry:
** After emerging, revived, through a portal onto the final battlefield, T'Challa leads the approaching Wakandan army in chanting "YIBAMBE!" ("hold the line"), [[MeaningfulEcho reprising the similar moment]] from ''Infinity War''.
** And of course...
--->'''Captain America:''' ''[backed by every living hero of the movies, facing down the armies of Thanos]'' '''AVENGERS!''' ''[summons Mjölnir]'' ''Assemble.''
* BattleInTheRain: Ronin vs. Akihiko in Japan while rain falls like the anguish in the former's heart.
* BeardOfSorrow: Thor, having wallowed in shame and self-pity for five years because he failed to kill Thanos in Wakanda, has grown a large, unkempt beard and is noticeably out of shape. Inverted with Steve Rogers, who shaves his beard off after his darkest defeat.
* BearHug: Upon meeting him again for the first time in years, Thor hugs Rocket enthusiastically. Rocket doesn't appreciate being pressed against Thor's beer belly, though.
* {{Beatnik}}: When Tony Stark and Steve Rogers go back to 1970 to retrieve the Tesseract and additional Pym Particles, Tony is mistaken for a beatnik by his own father because of his beard.
* BewareTheSillyOnes: Scott Lang is comic relief for most of the movie, even though he's very important for the plot. Come the final battle, though, and as Giant-Man he punches Leviathans out of the sky and ''crushes'' Cull Obsidian (the strongest of Thanos's children in the previous movie) underfoot.
* BigBad: Thanos, once again, is the villain the heroes need to defeat in order to bring back half of the universe. In a subversion, the Thanos that wiped out half the universe is killed in the opening act of the film, but this does nothing to undo the damage he did, and the movie instead focuses on trying to pull ''that'' off, specifically a journey for the heroes to bring back their loved ones. It is a time-displaced Thanos from 2014 that takes the role of BigBad instead, after he learns the heroes are trying to undo his upcoming victory. Thanos becomes an even bigger bad, as now he isn't just trying to do a 50% depopulation, but totally wipe out the universe and restart it from the beginning.
* BigBadassBattleSequence: The Battle of Earth, a massive action scene involving '''40''' characters, all of whom have names and backstories. It's been hyped as one of the movie's selling points, even though none of it is shown off in the ad campaign for the film. It consists of pretty much every heroic force shown in the Marvel films coming together in one final clash against the Mad Titan's army amidst the ruins of the Avengers facility.
* BigDamnHeroes:
** When Tony and Nebula are left drifting through space in the ''Benatar'', Captain Marvel finds the ship and returns them safely to Earth.
** When Thanos's past self attacks the Avengers headquarters, Banner, Rhodey and Rocket are trapped in a section of the base about to be either crushed by debris or drowned. Fortunately, Scott is able to save them just in time for them to join the final battle.
** Steve gets his own during Thor and Thanos's fight to the death, showing up to save the Asgardians with Mjölnir in hand.
** Perhaps the '''biggest damn hero moment''' in the MCU happens right at the top of the final battle. When Captain America comes face-to-face with Thanos's enormous army, everything appears to be a lost cause... until Cap hears Sam Wilson's voice call out [[ContinuityNod "On your left"]]. [[TheCavalry Cue every resurrected superhero alongside Asgardians, Masters of the Mystic Arts, the Ravagers, Wakandans, and more]] emerging from portals to create an army of their own.
** Cull Obsidian gets Korg in a headlock and is clearly overpowering him, but Drax runs in to start stabbing his back, giving Korg an opening to fight back.
** Spider-Man gets one when he saves Iron Man from Cull Obsidian by pulling TheBrute away from him for Giant-Man to step on and kill.
** Captain Marvel again in the climax, when her presence alerts Thanos's ship and they stop their bombardment on the battlefield to focus on her. She then destroys the entire ship herself in a matter of seconds.
** Rocket is about to be devoured by a huge flying monster when it and the rest of Thanos's entire army is ReducedToDust.
* TheBigDamnKiss: ''Endgame'' closes on Steve and Peggy passionately kissing while dancing to the tune of "It's Been a Long, Long Time" when he goes to 1948, fulfilling a lost romance that has endured for most of the saga's history.
* BigDamnReunion: Towards the end of the film. Cap is all alone to face Thanos's massive army, until the resurrected Sam Wilson comes in, along with every previously snapped hero for a 5 years overdue reunion.
* BigGuyRodeo: As the final battle gets heated, Drax the Destroyer jumps on Cull Obsidian's back to stab him and help save Korg, who the former had put in a headlock.
* BigYes:
** A comedic one, when 2012 Thor revives 2012 Tony with MagicalDefibrillator.
** Rocket shouts "OH, YEAH!" when Captain Marvel enters the battle and destroys the ''Sanctuary II''.
* BittersweetEnding:
** The Avengers finally repair the damage Thanos has done to the universe at the end of ''Infinity War'' by traveling back in time to retrieve the Infinity Stones across different timelines, reviving everyone who got dusted by Thanos's fingersnap, and culminating in Tony using his own Infinity Gauntlet to, in turn, fingersnap Thanos and his army into oblivion. Unfortunately, their victory came at a steep price: Natasha sacrifices herself to help Clint re-acquire the Soul Stone in Vormir, Tony dies using the Stones on Thanos, and Steve, having returned the Stones to their original timelines, chooses to stay in the 1940s and live the rest of his days in married retirement with Peggy, though at least he lives long enough to pass his shield and mantle to Sam Wilson. Additionally, the Avengers H.Q. has been completely annihilated by Thanos's forces, and the future of the team itself is left ambiguous at the end of the film.
** Furthermore, things are not fully restored to pre-''Infinity War'' days. While the 2014 version of Gamora lives on in the current timeline, the version of Gamora from the original timeline is dead for good, something that Star-Lord is clearly upset over even though he tries to hide it, since this Gamora never fell in love with him. The Vision is also still destroyed, and without the Mind Stone, there is not a clear way to bring him back -- although Wanda has seemingly made peace with this.
** On a smaller note, even after bringing everyone back, there's the fact that they lost five whole years of time with their loved ones. Like Scott losing out on seeing his little girl grow into the teenager she was when she opened the door for him. Now all of the returned victims have to adjust to a world that's moved on without them.
** Lastly, with the Infinity Stones reduced to atoms, the universe is open to all sorts of threats the stones had previously been used to protect them from, for instance extra-dimensional {{Eldritch Abomination}}s like [[Characters/MCUDarkDimension Dormammu]].
* BodyguardingABadass: During the final battle, all the major female characters show up to give Carol backup while she makes a run towards Scott's time machine, even though she's by a wide margin the most powerful person on the planet and had just [[DynamicEntry arrived by plowing through a massive starship]].
* BodyHorror: Using the full power of the Infinity Gauntlet isn't good for anyone's health.
** Thanos, after using the Stones twice, is reduced to a broken, limping wreck, the entire left side of his body burnt and blackened and his gauntlet arm essentially lame by his side. The fact that he didn't remove the now useless gauntlet also implies it has fused with his flesh.
** Using the Stones just once is enough to scar Professor Hulk the same way, and fatally injure Tony Stark.

* BookEnds:
** The original six Avengers from ''Film/{{The Avengers|2012}}'' all survived the events of ''Infinity War'', and reassemble (and team up with the other surviving heroes) to put an end to Thanos's conquest for universal "[[KillEmAll balance]]" that started with the Chitauri attack on New York City.
** Character design-wise, Captain America and Iron Man, the MCU's two biggest players, whose stories are wrapped up in this movie, wear outfits that look almost exactly like their classic comic book designs instead of the MCU's signature "modernized" look. Tony doubles up by having a similar black tank top to the one he had in the original ''Film/IronMan1''.
** Tony Stark's iconic "[[Film/TheAvengers2012 If we can't protect the Earth, you can be damned well sure we'll avenge it]]" line goes full circle considering they indeed ''couldn't'' protect the Earth, but are now seeking Thanos to avenge the fallen.
** Iron Man is back in the same kind of dilemma he was in at the beginning of [[Film/IronMan1 his first movie]]: trapped in a prison on borrowed time, with his only hope for survival depending entirely upon someone else helping him out, surviving only off of materials that he has within his prison. As an added bonus, he's even wearing the same kind of shirt that he did when he was in that cave in Afghanistan.
** Cap is wearing the same S.H.I.E.L.D. uniform that he wore in ''Film/CaptainAmericaTheWinterSoldier'' -- the first film in the Russo Brothers' MCU run. ''Endgame'' happens to be the last in the Russos' MCU run.
** Tony's FamousLastWords, and the ones that finally mark the end of the battle, are the same words that ended [[Film/IronMan1 the first movie]]: "I am Iron Man."
** Also going back to his first movie, there the arc reactor turned back on after the climactic battle showing he survived. Here it turns off to signify his death.
** Spanning back to ''[[Film/AvengersInfinityWar Infinity War]]'', the earlier film ends with Thanos watching the sunrise, as he smiles in pride having accomplished his goal. This film ends with Thanos watching the sunrise, as he bows his head in shame having failed.
** It also closes out his very first appearance in ''Film/{{The Avengers|2012}}''. There he stood up and smiled at the thought of facing the Avengers. Here he sits down and bows his head defeated by the Avengers.
** Moments before his death, present-day Thanos defiantly proclaims "I am inevitable" to the Avengers. In the final battle, before [[OhCrap he realizes that Iron Man has the Infinity Stones]], Past Thanos arrogantly proclaims "I am inevitable". It was definitely intentional on his part, since he had watched Nebula's memory of 2018 Thanos's death in which some of his last words were declaring "I am inevitable" to proclaim his victory, and believed he was about to succeed again.
** The song that closes out the film, "It's Been a Long, Long Time", was previously used in Joe and Anthony Russo's first Marvel movie, ''Film/CaptainAmericaTheWinterSoldier''.
** After the credits, the sound of Tony hammering together his very first suit from all the way back in the opening act of ''Film/IronMan1'' plays.
** Tony begins the film recording a potential ApocalypticLog / VideoWill for Pepper in case of his death. His final scene has the cast viewing another one he made five years later for her and Morgan at his actual funeral.
** While Thanos has gained and lost a multitude of archnemeses in his 46-years-and-counting comic book history, he was first introduced in the pages of ''ComicBook/IronMan'' Vol. 1 #55. Therefore, it is only fitting that Iron Man himself would see him out. Bonus points for having his creator, Jim Starlin, [[CreatorCameo make an appearance for this event]].
** ''Film/CaptainAmericaTheFirstAvenger'' -- Steve Rogers' MCU debut -- had him begin his career as Captain America and fight the Red Skull, who was wielding an Infinity Stone (the Tesseract/Space Stone), and then get frozen into the 21st century. ''Endgame'' -- which is meant to close out Rogers's CharacterArc -- ends with him travelling ''back'' in time and return the Infinity Stones back to their proper eras, including Vormir in 2014 -- which was where the Red Skull ended up after ''The First Avenger''.
* BraidsOfBarbarism: Thor gets braids in his hair and beard when he powers himself up with lightning before the final battle.
* BrickJoke: Both in-movie and on a franchise-wide level.
** Within the film itself:
*** Rocket and Nebula end up finding a garbage scow of a ship that Danvers pinged as hostile. On Vormir, Nat, who had been point for the expeditions Nebula, Rocket and Carol were on at the time, responded to Clint's observation of Rocket ''not'' being a raccoon by saying "he eats garbage" as well as mentioning to Scott that she got "e-mails from a raccoon" which made nothing sound crazy to her. This also hearkens back to the multiple times Rocket asks what a raccoon is whenever someone calls him it (normally Quill).
*** Scott is not happy that Tony refused to help the team at first, and reminds him later in the movie after the botched attempt to steal the Tesseract.
---->'''Scott:''' You're repeating yourself! You're repeating yourself!
*** ''Back to the Future'': Tony is thinking Scott is basing his theory for time travel on this film, which Scott denies. When Bruce debunks every theory he and Rhodey had, he quips "So ''Back to the Future'' is a bunch of bullshit??"
** Carrying over from other movies:
*** Steve Rogers making Mjölnir budge during the "lift the hammer" party game from ''Age of Ultron'' pays off when Cap finally lifts and wields Mjölnir in the finale, with Thor gleefully saying "I knew it."
*** Scott tells Hank his days of "breaking into places and stealing shit are done" in ''Ant-man''. Played with in this film; he and the Avengers break into other timelines and steal the Stones (and Mjölnir).
*** When Clint returns from his time travel test run, Scott can be seen in the background holding some orange slices, the same snack he requested in ''[[Film/CaptainAmericaCivilWar Civil War]]''.
*** Steve Rogers is shown [[NotSoAboveItAll swearing several times]], despite being kidded for reprimanding others for their language in ''Age of Ultron''.
*** After being [[InterruptedByTheEnd teased]] in ''Age of Ultron'', Steve Rogers finally says "Avengers Assemble!"
*** After Rocket steals the Aether, he's chased down by a horde of Asgardian guards who cry, "get that rabbit!" just like Thor has mistaken Rocket for a rabbit.
*** Tony Stark being reluctant to call his hug to Peter at the start of ''Homecoming'' a hug, comes back when he unambiguously hugs him.
*** In a darker vein, Doctor Strange saying he wouldn't hesitate to sacrifice either Stark or Spider-Man if it meant saving the world, becomes this when Strange confirms to Stark at the end that the one timeline in which Thanos is defeated ultimately rested on Stark performing a HeroicSacrifice. Strange really wasn't kidding around.
*** In the same darker vein, Tony finally disproves Steve's argument from the first movie that Tony will never make the big sacrifice (though it's not like he didn't try to do so in the first movie).
*** Likewise, Tony's argument (as well as Red Skull's) that everything special about Steve came from the super-soldier serum is proven definitively wrong by Mjölnir, and by extension Odin himself.
*** Early in the film at Tony's house, he finds Morgan wearing the helmet for the suit of armor he made Pepper, and jokingly complains that "Mommy never wears anything I make her." Guess who shows up, in a suit of armor, at the final battle?
*** During the tarmac fight in ''Film/CaptainAmericaCivilWar'', Hawkeye introduced himself to T'Challa as Clint, and T'Challa answered, "I don't care." During the final battle, when Hawkeye is carrying the nano-gauntlet with the Infinity Stones, only to be surrounded by Thanos's forces, T'Challa remembers his name and says, "Clint, give it to me!"
* BringIt: Aside from a moment of surprise, Thanos's reaction to the Avengers bringing in a massive army of allies in the form of the Wakandans, Asgardians, Ravagers, Khamar-Taj, and more, which then charges at him, is to simply lift his blade with a satisfied smile and order his army to do likewise.
* BrokeYourArmPunchingOutCthulhu: Tony succeeds in defeating Thanos and his forces by snapping with the Infinity Stones, but wielding their power completely fries his human body to the point of dying just a few minutes after using them.
* BrutalHonesty: More than one character tells Thor either that he failed, or that he is a failure.
-->'''Thor:''' That's a little bit harsh...
* TheBusCameBack:
** After sitting out ''Infinity War'', Hawkeye and Ant-Man return.
** Harley Keener, the kid from ''Iron Man 3'', makes a reappearance at Tony Stark's funeral.
** When Thor and Rocket time travel back to the events of ''Film/ThorTheDarkWorld'', both Jane Foster and Frigga show up. Along with Mjölnir.
** The Ancient One from ''Film/{{Doctor Strange|2016}}'' appears in the 2012 New York timeline, four years before Stephen Strange started practicing the Mystic Arts with her.
** Likewise, Brock Rumlow, Jasper Sitwell, and Alexander Pierce (not yet unmasked as ComicBook/{{HYDRA}} moles) show up when Tony, Steve, and Scott bump into them in the aftermath of the Battle of New York).
* BusCrash: According to the Russos, both [[Film/TheIncredibleHulk Betty Ross]] and [[Film/{{Thor}} Lady]] [[Film/ThorTheDarkWorld Sif]] were [[KilledOffscreen turned to dust]] by the end of ''Infinity War''. Although her demise wasn't shown in ''Infinity War'', [[Film/BlackPanther2018 Shuri]] was another victim. [[FreezeFrameBonus Freeze Frame Bonuses]] confirm that Erik Selvig and Sharon Carter also died.
* ButForMeItWasTuesday: This is played with. 2018 Thanos killed Vision to get the Mind Stone. When Wanda is brought back, she is furious at Thanos, even though she is speaking to his 2014 counterpart, and [[FishOutOfTemporalWater he genuinely doesn't know who she is]].
* ButtMonkey:
** Star-Lord. His past incarnation of him is knocked out by Rhodey after both he and Nebula call him an idiot. His present incarnation after being revived runs into the past Gamora, who [[GroinAttack kicks him in the groin]] when he moves on her because she doesn't know him yet, and finally, his position as the leader of the Guardians is contested yet again when Thor tags along with the crew in the ending, in spite of Thor still being horrendously out-of-shape and still recovering from his depression. Peter Quill just can't catch a break.
** Even if he is essentially a HopeBringer for the heroes, Scott fares worse than Peter in this regard since he has a much larger role. Getting hit with both RapidAging and [[FountainOfYouth de-aging]] one after another in a single scene is just one of the many embarassments he goes through.
** Cull Obsidian gets manhandled pretty badly during the Battle of Earth. Even though he takes point in leading Thanos's army forward, he is immediately knocked down by Cap with Mjölnir before he can even land a hit on someone. Cull gets back up and manages to get Korg in a headlock, but then Drax hops on his back to stab him repeatedly, and Korg is able to get free and smack him in the face. Finally, Cull once again attacks Iron Man, but Spider-Man is able to hold him in place with his webs long enough for Giant-Man to fatally crush him under his foot. For all his being the biggest and toughest of Thanos's children, Cull barely lasts a ''minute'' in the final battle.

* CallBack:
** Tony mentions his nightmare from ''Film/AvengersAgeOfUltron'' and bitterly references his "suit of armor around the world" plan and that promised they would fight and lose [[TheTeam together as a team]]. (See CallingTheOldManOut below.)
** When the team have Thanos restrained at the beginning of the movie, Thor decapitates him. His response when asked "what did you do"?
--->'''Thor:''' ''[bitterly]'' I went for the head.
** Scott tries to remind the Avengers of his presence with his contributions to the Leipzig-Halle airport fight in ''Film/CaptainAmericaCivilWar''.
** At the end of ''Film/CaptainAmericaCivilWar'', Steve surrendered the shield after Tony shouted, "That shield doesn't belong to you! My father made it!" When Tony returns to Avengers Compound to assist with their plan to retrieve the Infinity Stones, he returns Steve's shield, commenting, "He made it for you."
** In ''Film/ThorRagnarok'', Odin tells Thor in a vision that the field in Norway where he died could be Asgard, because Asgard is its people. This is where the surviving Asgardians settle to establish "New Asgard".
** During their attempt to recruit a drunken and despondent Thor, Bruce mentions how much [[Film/ThorRagnarok Thor's help on Sakaar]] meant to him when he was trying to merge his brains with the Hulk's brawn.
** The events of the Time Heist feature call-backs to the films that took place during those times along with other films in the MCU:
*** Captain America dons his original outfit from the first ''[[Film/TheAvengers2012 Avengers]]'' movie at one point in the film. He does this to blend in when he, Ant-Man, Hulk and Iron Man travel back to the aftermath of the Battle of New York so that they can get the Space and Mind Stones.
*** While trying to get the scepter, [[Film/CaptainAmericaTheWinterSoldier Cap is in an elevator full of HYDRA agents (including Rumlow) who are trying to act like everything's normal, but are clearly ready for a fight]]. This time he bluffs his way out.
*** When Professor Hulk tries to take the Eye of Agamotto from the Ancient One without so much as a by-your-leave, she calms him down by knocking his astral form out of his body, like she did to [[Film/DoctorStrange2016 Stephen Strange]] when he got too exasperating for his own good.
*** Thor and Rocket are tasked with retrieving the Reality Stone from Asgard just before it is attacked by the Dark Elves during ''Film/ThorTheDarkWorld''. This allows Thor to have a heart-to-heart with his mother Frigga shortly before her predestined death.
*** War Machine and Nebula head to the planet Morag from the beginning of ''Film/GuardiansOfTheGalaxy'' so that they can get the Power Stone before the past version of Star-Lord steals it.
*** In the 1970s, Tony and Steve end up at the army base where S.H.I.E.L.D. set up shop after WWII. Tony doesn't know where the entryway is. But Steve, however, does from his time in ''Film/CaptainAmericaTheWinterSoldier'', pointing out the same munitions bunker entryway that he had gone (or will go) through.
** The mambo drum rattle used to kick off Luis' stories in ''Film/AntMan'' can be heard during pivotal moments of the Time Heist, like Scott breaking into past Tony's arc reactor.
** The Hulk ends up being the one to use the Infinity Stones to resurrect everyone who died in the decimation, as the Stones give off harmful gamma radiation that only his body can withstand. Earlier, when searching for the Tesseract at the S.H.I.E.L.D. facilities, a FreezeFrameBonus shows that Tony's glasses are specifically tracking a gamma radiation signature. Back in the first ''Avengers'' movie, S.H.I.E.L.D. tracked down Bruce because the Tesseract emitted gamma radiation that he knew all about. In the same film, Tony mused that maybe Bruce had survived the gamma accident that turned him into the Hulk for a reason, and it looks like he was correct.
** Thor uses his lightning to power up Tony's armor during the final battle with Thanos, a nod to the scene in the first ''Avengers'' movie where he accidentally charged up the armor during his initial fight with Tony.
** During the final battle, Captain America is able to lift Mjölnir, referencing the scene where he was actually able to slightly budge the hammer in ''Film/AvengersAgeOfUltron''.
** One of the moves that Steve uses involves his shield and Mjölnir colliding behind Thanos during his fight before the big battle begins, the shockwave throwing him off his balance. In the first two ''Avengers'' films, this combo move was performed with both Thor and Steve (in the first film, it's discovered during the first fight between Tony and Thor and used during the Battle of New York. In the second film, Steve and Thor use it while the Avengers assault the HYDRA castle at the start of the film. The move Steve does in this film marks the third and final time it's seen on screen).
** Spider-Man activates the [[Film/SpiderManHomecoming Instant Kill Mode]] in the final battle.
** What are Tony Stark's [[FamousLastWords last words]] before using the Infinity Gauntlet to snap Thanos and his army into oblivion? ''"I am Iron Man!"'' -- the same words that he said when he first revealed his identity to the world in ''Film/IronMan1''. [[BookEnds He ends his journey with the same bold declaration that began it.]]
** Also a slight BookEnd of sorts, in ''Film/IronMan1'', Pepper threatened to quit when she saw Tony endangering himself by wearing the Iron Man suit, but Tony convinced her to stay by informing her of his change of heart. Here, he does die in battle, but as a HeroicSacrifice rather than getting himself killed like she feared, and she's the last person with him before he passes.
--->'''Pepper:''' ''[in 2008]'' [[DramaticIrony You're gonna kill yourself, Tony, I'm not gonna be a part of it.]]
%%** "On your left!" is in ContinuityNod.

* CallToAgriculture:
** As seen in ''Infinity War'', after dusting half the universe, Thanos moved to a place called "The Garden", where he's shown harvesting crops and cooking them. When the Avengers learn of his location, Rhodey comments, "That's cute, Thanos has a retirement plan".
** Hawkeye has been toying with retiring from the secret agent/superhero life to be with his wife and kids on the farm since the end of ''Age of Ultron''. Once the snap is reversed and he ''has'' a wife and kids back on the farm again, he decides to make another go at it.
* CallingTheOldManOut: Tony does this to Steve ([[OlderThanTheyLook who at this point is nearly 100 years old]]) over his broken promise from ''Film/AvengersAgeOfUltron'' to fight together to combat any threat from space rather than trust a "suit of armor around the world."
-->'''Tony:''' I saw this coming a few years back. I didn't wanna believe it -- thought I was dreaming. ... And I remember telling all of you that what we needed was a suit of armor around the world. Remember that? Whether it impacted our precious freedoms or not -- that's what we needed!\\
'''Steve:''' Well, that didn't work out, did it?\\
'''Tony:''' I said we'd lose. You said, "We'll do that together too." And guess what, Cap? We lost, and you weren't there. ... I got nothing for you, Cap! I got no coordinates, no clues, no strategies, no options. Zero. Zip. Nada. No trust, liar.
* TheCameo:
** One of the Russo brothers, Joe Russo, cameos as the grieving man attending a group therapy session with Captain America after the five years timeskip. Also present is Creator/JimStarlin, creator of Thanos and writer/artist of ''The Infinity Saga'' in the comics.
** Creator/StanLee has one, [[OncePerEpisode as usual]], where during the time travel to 1970 in New Jersey, he drives next to an army base, shouting "Make love, not war," a reference to his counterculture fanbase at the time. It is one of the last live-action cameos he filmed before he passed away, and is officially his final cameo in the Marvel Cinematic Universe.[[note]]Lee's likeness appeared in ''WesternAnimation/RalphBreaksTheInternet'' and he voiced a cameo in ''WesternAnimation/SpiderManIntoTheSpiderVerse''. Creator/JamesGunn also helped him film a number of cameos for Marvel movies before other Marvel movies actually started production.[[/note]] Worth noting is that the woman who is in the car with him is a de-aged version of his wife, portrayed entirely through CGI due to Joan Lee's death in 2017.
** In the ongoing tradition of actors from ''Series/{{Community}}'' appearing in the MCU, Yvette Nicole Brown shows up in the S.H.I.E.L.D. facility when Steve and Tony infiltrate it in 1970.
** Creator/KenJeong (also from ''Community'') appears as the security guard for the deep storage facility where the "disgusting van" has been sitting for 5 years.
** Howard the Duck can be seen in the background during the final battle.
** Creator/HiroyukiSanada is the yakuza that Ronin hunts and kills right before Nat recruits him.
** One of the people at Stark's funeral is Harley Keener, aka the kid who helped Tony in ''Film/IronMan3'', once again played by Ty Simpkins. Quite a few viewers were caught off guard since it had been six years since he was last seen.
* CantTakeCriticism: Upon finding out [[DespairEventHorizon just how people feel]] about his "balancing" of the universe in [[Film/AvengersInfinityWar the previous film]], as well as the fact that the Avengers are trying to undo it, Thanos [[JumpingOffTheSlipperySlope goes from simply misguided to completely insane]]. A few minutes of criticism is all it takes to make him decide to [[OmnicidalManiac kill the whole the universe]] and make a new world that ''will'' [[ItsAllAboutMe appreciate his actions and love him as a hero]].
* CastingGag:
** The two cast members of ''Series/ParksAndRecreation'' (Creator/ChrisPratt and Creator/PaulRudd) are dismissed as idiots by Nebula and Rhodey. Fittingly, both their characters (Andy Dwyer and Bobby Newport) are [[TheDitz ditzy]] [[ManChild manchildren]], but [[NiceGuy nice guys]].
** Also, the[[invoked]] [[MemeticMutation memetically]] [[OlderThanTheyLook ageless]] Creator/PaulRudd plays the character who accidentally travels five years into the future and does not age, while the others who survived the snap have aged visibly.
* CastFromHitPoints: Using the Infinity Gauntlet extracts a heavy toll. Thanos is crippled from the combined efforts of the Snap and his subsequent destruction of the Stones, Hulk is wounded and weakened after donning the Stark Gauntlet despite his great endurance and innate resistance to the gamma radiation released by its use, and Tony's attempt at using the Gauntlet -- though ultimately successful -- [[HeroicRROD kills him, implicitly by burning out his heart]].
* TheCavalry: An entire army of Wakandans, New Asgardians (which include Korg and Miek among them), Masters of the Mystic Arts, and Ravagers (among other groups), united behind the Avengers, charge across the field against the hordes of Thanos's forces.
* CelebrityParadox:
** The time-travel films mentioned when the Avengers discuss using the Quantum Realm to go to the past:
*** ''Film/HotTubTimeMachine'' stars Creator/SebastianStan, who plays Bucky.
*** ''Film/StarTrek2009'' stars Creator/ZoeSaldana, who plays Gamora, and Creator/KarlUrban, who played Skurge, and also features Creator/ChrisHemsworth, who plays Thor. The greater franchise features quite a few actors who appeared in the MCU such as Creator/BenedictCumberbatch, who plays Doctor Strange, and Creator/IdrisElba, who plays Heimdall.
*** If they mean the ''Film/{{A Wrinkle in Time|2018}}'' film released in 2018 and not the books, that film stars Creator/MichaelPena, who plays Scott's friend Luis.
*** Scott suggests ''Franchise/DieHard''. Creator/WilliamSadler, who was in ''Film/DieHard2'', plays President Matthew Ellis. Creator/SamuelLJackson, who was in ''Film/DieHardWithAVengeance'', plays Nick Fury.
** Thor's looks after five years of letting himself go and [[DrowningMySorrows drinking like crazy]] make him resemble [[Film/TheBigLebowski the Dude]] so much that Tony even snarkily calls him "Lebowski" at one point. [[Creator/JeffBridges The Dude himself]] played the BigBad Obadiah Stane all the way back in 2008's ''Film/IronMan1''.
** Korg can be seen playing ''VideoGame/{{Fortnite}}'', a video game in which Thanos was playable during a limited-time event.
* CentralTheme: Second chances. You may have failed once, but never give up. Use your failure to create an even better success.
* CerebusRollercoaster: The second arc of the movie (the Time Heist) has significantly more humor and is more brightly lit compared to the somber first act and the apocalyptic final arc because a 2014 version of Thanos invades Earth. However, the arc itself whiplashes back to serious during Black Widow's sacrifice.
* CharacterDeath: Though all those that were dusted in the previous film return, those that died otherwise (Loki, Heimdall, Gamora, Vision) remain deceased, albeit a past version of Gamora lives. On top of these, Natasha sacrifices herself so Clint can take the Soul Stone, with no hope of bringing her back. The final death in the film is Tony Stark himself, having used the Infinity Stones to wipe out Thanos's forces at the cost of his own life.
* CharacterDevelopment:
** Steve Rogers's loosening up over time is demonstrated when he travels to 2012. Rather than fight all the HYDRA agents in the elevator to get the scepter as he would have done a few years ago, he says "Hail HYDRA" to convince them to just hand it over. Later, he curses when he encounters his 2012 self and knows a fight is inevitable. During the ensuing scuffle, Steve is shown to be a CombatPragmatist compared to his past self when he says, "Bucky's still alive!", causing 2012 Steve to let his guard down and allowing present-day Steve to escape the chokehold and knock him out with the scepter.
** Thor's maturation from a pompous, arrogant braggart and BoisterousBruiser to a grieving, tormented survivor to a noble, selfless, and modest warrior is highlighted in the final battle. In ''[[Film/AvengersAgeOfUltron Age of Ultron]]'', Cap merely ''nudging'' Mjölnir was enough to make Thor [[OhCrap momentarily panic]] because he had built his entire concept of self-worth around being the only person [[OnlyTheChosenMayWield worthy of wielding the hammer]]. In ''Endgame'', there's not a trace of jealousy in him when Thor sees Captain America swinging Mjölnir around like he's had it for years, and he joyously says "I knew it." He even ''prefers'' Steve use Mjölnir in battle while he use Stormbreaker, because he knows he's not [[Film/ThorRagnarok Thor, God of Hammers]] and he's [[SoProudOfYou delighted to see his friend proven worthy.]]
** Nebula's Character Development is given a measuring stick to show how far she's come by this point when she faces her 2014 self, still fanatically loyal to Thanos.
** A smaller case, but nonetheless notable. Pepper has always been a case of WetBlanketWife towards Tony, [[Film/CaptainAmericaCivilWar even leaving him at one point]] when [[Film/AvengersAgeOfUltron he failed]] to fulfill his promise to [[Film/IronMan3 fully retire]]. While she does [[Film/SpiderManHomecoming get back together with him]], even when we last see her in ''Infinity War'', she still has shades of being a WetBlanketWife towards him when pointing out his arc reactor. In her two most prominent scenes here, however, we see that Pepper has long moved past that and, in fact, is the one who encourages Tony to help undo the Snap now that he knows the way to do so, citing both her acceptance that she could never stop Tony before, and that him not going through with this will haunt him in his sleep. It's telling that her last words to him as he dies from using the Gauntlet are not of pleas for him to stay alive, but of genuine assurance that he did everything he could and he can now rest. The fact that she [[BattleCouple willingly joins the final battle in the Rescue Armor]], despite Tony believing she would never wear it, shows how much she herself has grown.
* ChekhovsArmy:
** In the final battle against Thanos and his forces, every single hero who appeared in films prior (minus ones whose [[KilledOffForReal deaths are permanent]], like Natasha, Vision, or Heimdall) and their allies show up to assist the Avengers, forming a massive army spanning multiple alien races, gods, sorcerers, and technologically augmented humans.
** The film itself features many past characters (who are dead at the present point in the story saga) through time travel, such as Howard Stark, Loki, Peggy Carter, Frigga, the Ancient One, and Alexander Pierce.
* ChekhovsClassroom: Scott tells everyone that they only have one vial of Pym particles left since they lost Hank Pym to the Snap, which inspires Steve to find the part of the S.H.I.E.L.D. facility where Hank worked in 1970, and steal some fresh vials.
* ChekhovsGun:
** Hank Pym mentioned many times in the two Ant-Man films that the time and space work differently in the Quantum Realm and his wife even mentioned that there are time vortexes in there. This give Scott Lang the idea to use time travel to reverse the damages Thanos caused.
** Janet Van Dyne's prolonged stay in the Quantum Realm has given her Quantum Powers which, among other things, allowed her to stablize the molecules of those who are suffering from quantum displacement. Similarly, Scott was stuck in the Quantum Realm for five years (or five hours from his perspective) and while it is not explored, it most likely changes him as well, which explains how he is able to stay as Giant-Man for longer periods than before without showing any signs of exhaustion.
** In 2012, following the events of the New York battle, the Hulk is forced to take the stairs after the Avengers insist he won't fit in the elevator, and he angrily does so. Later, he swings the door open as Tony is about to walk away with the Tesseract, knocking him out and allowing Loki to escape with it.
** One which spans multiple movies: while trying to stop Thanos's forces from reaching the new Infinity Gauntlet, Spider-Man finally sees fit to activate [[Film/SpiderManHomecoming Instant Kill Mode]].
** While Tony's daughter Morgan plays with Pepper's Rescue mask, he tells her that Pepper doesn't wear it. During the final battle, she does.
** At the end of ''Infinity War'', after handing over the time stone to Thanos, Doctor Strange breaks down while apologizing to Tony Stark, saying it was the only way. ''Endgame'' reveals that he wasn't just apologizing for handing over the stone, but for setting in motion a plan that will require Tony's death.
** The Iron Man suit's infinity gauntlet that is holding the infinity stones. The moment Thanos attempts his second snap (seconds after having wrestled his hand free from Iron Man), it turns out that all the stones are gone... and have migrated over to ''Stark's'' gauntlet. Apparently he built a failsafe into it to prevent exactly this from happening.
* ChekhovsSkill: Tony and Nebula kill time while adrift in space by flicking a paper football back and forth. Incredibly, this comes into play during the Time Heist, when Tony needs to flick Ant-Man across a room and onto the HYDRA agent carrying the Tesseract in a briefcase.
* ChokeHolds: 2012 Steve Rogers puts present Steve Rogers in a chokehold, thinking that he is a disguised Loki. Present Steven Rogers manages to free himself by distracting his past self, saying that Bucky is still alive.
* ClimacticBattleResurrection: The victims of the Snap return to life for the final battle.
* ClipShow: Fitting for a finale. A subverted example occurs when the characters travel through time to collect the Infinity Stones. We get some clips, and some old scenes from new angles from ''The Avengers'', ''Thor: The Dark World'', and ''Guardians of the Galaxy''. But once the time-traveling present-day Avengers start altering events, there's plenty of new content, too.
* CloseEnoughTimeline: Steve returns to various timelines to return their Infinity Stones to make sure those realities more or less proceed along the same path as their own, rather than letting dark realities where TheBadGuyWins occur due to Captain Marvel never existing due to the Tesseract disappearing, Doctor Strange not being able to stop Dormammu due to lacking the Time Stone, Thor never stopping the Dark Elves due to lacking Mjölnir, and so on. However, Joe Russo confirmed in an [[https://www.businessinsider.de/avengers-endgame-directors-describe-making-of-the-movie-interview-2019-5?r=US&IR=T interview]] that Loki created an alternate timeline when he teleported away with the Tesseract in 2012, and that it would be "impossible for [Cap] to rectify the timeline unless he found Loki."
* ClothingDamage: Lampshaded when Professor Hulk says he's wearing shirts now. On travelling back to the past, he obligingly rips his own shirt off in order to pass as the Big Green Rage Monster.
* CollapsibleHelmet: Beyond the usual suspects from previous movies (Ant-Man, Iron Man, War Machine, Black Panther, Spider-Man, Star-Lord...), the quantum suits are made from nano-tech and can fully collapse. The helmet is the first to come off after a trip, even if the rest of the suit stays. This allows the protagonists to show their faces at almost all times, except when the helmets are an absolute necessity, i.e. during trips in the Quantum Realm.
* ColorMotif:
** In contrast to the neon-tinted teaser poster used for ''Infinity War'', the teaser poster for ''Endgame'' is a mix of purple and blue. This extends to some of the promotional material as well, as an abandoned New York City is seen bathed in a blue marine layer in the Big Game TV spot.
** The new [[https://www.comingsoon.net/movies/news/1053577-avenge-the-fallen-with-new-avengers-endgame-character-posters "character posters"]] are full color for the characters who survive but black and white for those who have died.
* CombinationAttack: Pepper, Shuri and the Wasp fire their weapons at Thanos to try to keep him at bay as Danvers cruises past him to the van.
* ComedicSociopathy: Thor threatens a young ''Fortnite'' player that he will come to the latter's place and tear off his arms, then taunting him further when he seemingly makes the child cry.
* ComfortFood: In addition to [[DrowningMySorrows drinking alcohol]], Thor is eating junk food.
* ComfortTheDying: Tony Stark, a.k.a. ComicBook/IronMan, is suffering from the CastFromHitPoints effect of the [[{{Superweapon}} Infinity Gauntlet]], which he has just used to utterly disintegrate a GalacticConqueror and his armies. In his final moments, his best friend, his protégé, and his wife are the ones to comfort him as he struggles to stay alive, but it's [[HopeSpot a battle Tony is losing]], and they all know it, as the toll of the Infinity Gauntlet had [[ChekhovsBoomerang already been established]] as nearly too much for [[TheBigGuy Hulk]] at peak condition, whereas Tony used it after a prolonged skirmish that left him running on fumes. With Tony's stubbornness serving only to prolong his pain, he finally passes, peacefully, when his wife tells him that they'll be okay thanks to his HeroicSacrifice.
* TheComicallySerious: Mantis, who proves she is capable of being silly and serious at the same time. This is especially obvious when she is seen charging into battle with M'Baku, Thor, and Captain America.
* ComicBookMoviesDontUseCodenames:
** Clint Barton is never called "Ronin" at any point in the movie.
** Likewise, while Pepper does finally don her armor, she's not called "Rescue" by anyone.
** Much like her debut solo, Carol Danvers is never called Captain Marvel.
* CompositeCharacter: Clint Barton. Much like his 616 incarnation, he takes the identity of Ronin following [[Film/CaptainAmericaCivilWar Civil]] [[ComicBook/CivilWar War]], and his change in attitude and costume following the tragic deaths of his family is reminiscent of Ultimate Hawkeye. However, whilst Ultimate Hawkeye became a DeathSeeker, MCU Hawkeye instead goes down the same route as ComicBook/ThePunisher, and starts ruthlessly murdering criminals who survived the Decimation. He comes very close to sacrificing himself for the Soul Stone to atone for his actions as Ronin, reminiscent of his Ultimate counterpart's DeathSeeker tendencies, but Black Widow performs the HeroicSuicide before he can.
* ConquerorFromTheFuture: Inverted. Thanos's past self from 2014 is accidentally warned that he will fulfill his goal of erasing half of the population but that the Avengers are traveling to the past in order to steal the Stones. Capturing the Nebula from the present and acquiring her Pym particles vial, Thanos, his warship the ''Sanctuary II'', and his army all come to the present to get all the Stones at once from the Avengers.
* ContinuityCavalcade: When the Avengers are gathering all the infos they have on the Infinity Stones' whereabouts over the years, they recall in turn some of the adventures that we've seen in the previous movies, each putting their own twist on their respective tales.
* ContinuityNod: Has its [[ContinuityNod/AvengersEndgame own page]].
* ContrivedCoincidence:
** Scott's escape from the Quantum Realm happens entirely by luck when a rat accidentally activates the portal. Let us give proper gravitas to this: this simple, infinitesimally unlikely action of a rat walking over a control panel leads to the invention of time travel, the ability to recover the Infinity Stones that Thanos wiped out of existence, and the resurrection of literally ''trillions'' of creatures eradicated by the Decimation.
** Bruce's belief that he could get the Time Stone from Doctor Strange in 2012 was completely wrong. Luckily for him, the Ancient One just happened to have the Time Stone in her possession while she was protecting the New York Sanctum during the Battle of New York in 2012.
* CoolShades: {{Deconstructed|Trope}}. Thor wears sunglasses in various scenes, even inside. But it rather highlights his failed attempts to put up a happy and relaxed appearance in order to conceal how depressed he really is, than actually make him look cool.
* CoolShip: The ''Benatar'' returns, as well as Thanos's ''[[MileLongShip Sanctuary II]]''.
* CoolVsAwesome:
** As with the first film, a time-displaced super-soldier, a nanite-powered tech genius-cum-playboy, a scientist with the body of a radioactive mutant, a CIA spook turned crime-fighting vigilante, a raccoon, a Norse God and a BlueSkinnedSpaceBabe go on a time-traveling quest to undo mass genocide. The super-soldier winds up fighting a past alternate universe self, and the raccoon accidentally angers the guards of Norse Mythology.
** The climax features a wizard teleporting in more wizards, an intergalactic alien militia, the remainders of Norse Mythology, a fighter pilot turned cosmic energy conduit, and reality-warped-back-to-life superheroes fighting alternate dimension counterparts of a Mutant alien overlord seeking to become a god and his army, made of space gorillas, giant bio-mechanical snakes, and cybernetically-enhanced mutant aliens.
* CrapsackWorld: Zigzagged. After Thanos wiped out half of all life, major governments quickly took measures to maintain order -- but it's clear that the combination of grief, loss of life, unsupported infrastructure and the resulting power vaccuum is eroding humanity steadily. Carol also discussed that other planets in the universe are losing stability while she's working to fix it.
* CrazyEnoughToWork: Steve and Natasha's plan has [[MillionToOneChance incredibly low odds of actually working]], but they're so determined to avoid letting that stop them because everyone will suffer even more if they fail. The plan is to attack Thanos where he's [[RetiredMonster retired]] and, to their surprise, Thanos is completely alone and ''much'' weaker due to [[DentedIron destroying the Infinity Stones having cost the majority of his strength]]. So ''of course'' the heroes' plan works much easier than it should.
-->'''Natasha:''' This is gonna work, Steve.\\
'''Steve:''' I know it is. 'Cause I don't know what I'm gonna do if it doesn't.
* CreativeClosingCredits: The film uses the style of end credits from ''Film/StarTrekVITheUndiscoveredCountry'', by showing the signatures of the actors who played the original Avengers.
* CreatorCameo:
** Co-director Joe Russo plays a man in a support group for people losing love ones with Captain America. He is the first character openly on the LGBTQ spectrum portrayed in an MCU film. Thanos creator Jim Starlin is also a member of the support group.
** In Creator/StanLee's last cameo, he plays a hippie who drives past the entrance of Camp Lehigh, jeering at them. Lee was de-aged for this scene to look as he did in the [=1970s=], alongside a completely CGI recreation of his wife, Joan Lee, as she appeared at that time. This also marks the second time that Joan Lee had a cameo in a Marvel film after ''Film/XMenApocalypse''.
** When Scott is looking at the memorials for the people who vanished, many names listed are of people who worked on one or more Marvel films, including VFX editor Emily Denker, CG artist Geoff Diamond, animator Marco La Torre, and digital asset coordinator Susana Lou.
** Screenwriter and producer Christopher Markus appears briefly at the start of the 1970 sequence as one of the men entering the S.H.I.E.L.D. bunker.
* CringeComedy:
** When meeting up with Professor Hulk at a diner, a group of kids come up and ask for a photograph with him, to which he obliges, but then Lang asks the kids if they want a photo with him too, but since he's out of costume, they don't realize he's someone special, and as he tries to explain himself, Prof. Hulk at the same time is trying to cover for him, with Ant-Man just wanting the suggestion to be dropped, and Hulk trying to encourage the kids.
** When Tony accidentally teaches his daughter how to swear, we are "treated" to the hilariously horrifying sight of a tiny and adorable little girl cheerfully giggling "shit" (twice!) before Daddy Foul-Mouth hurriedly tries to teach her "You can't say that! That's mommy's word!"
** The hilariously shocking reveal that Thor has become [[{{Hikikomori}} an overweight alcoholic video-game junkie who spends all day indoors]] in ''only'' his underpants would be right at home in an Creator/AdamSandler gross-out comedy. You'll hate yourself for laughing ''with'' a grown-ass 1500-year-old God yelling at a 10-year-old Internet {{Troll}} over Playstation-Chat, threatening to "rip his arms off and shove them up his butt"... but you'll laugh anyways.
** When Thor tries to enlighten the other Avengers on the Aether/Reality Stone, he ends up rambling about Jane, Odin, and the nature of life. Eventually, Tony has to interrupt him and save him from himself as he babbles aimlessly.
** Overlapping with BlackComedy, Rhodes suggesting that the Avengers should just use the time machine to go back to when Thanos was a baby and strangle him with a garrote, pantomimed and complete with choking noises. Professor Hulk is naturally ''horrified'' by this proposal.
--->'''Rhodey:''' It's ''Thanos''.
** InUniverse literal example: Captain Rogers, Lang, Stark and Banner just ''have'' to bump into Hulk the way he used to be back in 2012 in their time-travel quest for the New York Infinity Stones. The first three men look on bug-eyed and stupefied as the Hulk violently jumps up-and-down on a car like a broken trampoline screaming like a five-year-old ''after'' using it to smash a Chitauri to death, while the now peace-loving Doctor Banner covers his face and cringes in humiliation.
* CryCute:
** Natasha is weeping while eating her peanut butter sandwich.
** When Thor is caught by Frigga, his mother, during his quest for the Reality stone travelling back in time, he thinks she will be ashamed of him because he is now an overweight alcoholic shut in. Instead, she assures him she still loves him, and encourages him to pick himself up and be the best person he can be, instead what others expect him to. This causes the former god of thunder to adorably weep like a little boy as his mom lovingly hugs him.
* CueTheSun: Although there's still some daylight when Thanos's ship arrives and the FinalBattle begins, the destruction of the landscape and ''Sanctuary II'' itself cover the land in dusty, thick gloom. Then, as Captain America [[DarkestHour prepares to make his final stand]], a luminous magical portal opens up behind him, revealing the noon sunshine of Wakanda. It's so bright that, when Okoye, Shuri, and T'Challa step out, it seems for all the world that they are stepping ''[[InvertedTrope out]]'' [[GoIntoTheLight of pure light]]. Then the rest of TheCavalry steps out from their own [[RaysFromHeaven sunlight-filled portals]].
* CurbStompBattle:
** The surviving Avengers and their allies manage to locate Thanos in his farm within the first twenty minutes of the film. By then he's already retired to a quiet life and has destroyed the Infinity Stones, which left him a fraction of his original strength. Captain Marvel, Bruce in the Hulkbuster, War Machine, and Thor quickly make short work of him. Justified since Thanos destroyed the Stones, he doesn't have his army, and [[DeathSeeker he wants to die anyways after murdering his daughter and half the universe]].
** The Hulk makes a move to attack the Ancient One to get the Time Stone. She knocks Banner right out of the Hulk's body with her astral strike.
** Past Thanos hands these out like candy, stomping almost every hero that tries to attack him. The only ones he couldn't stomp are an enraged Scarlet Witch, who instead matches and gradually overpowers him herself (to the point the last leg of their fight is practically a Curb-Stomp in its own right), and a fully-powered up Captain Marvel, which he needed the Power Stone to take out.
** Corvus Glaive gets unceremoniously ImpaledWithExtremePrejudice by Okoye. She barely even breaks stride in her forward charge.
** Giant-Man easily punches Leviathans out of the sky, ''and'' {{Goomba Stomp}}s Cull Obsidian with little effort; also he doesn't even seem winded as he did in ''Civil War'' and ''Ant-Man and the Wasp''.
* CurbStompCushion: While the past Thanos overwhelms the Avengers and if not for a last second sleight-of-hand would have won, they manage to get a few good hits in:
** Cap with the power of Mjölnir and his own skill in using his shield treats Thanos like a ragdoll, until he figures out his tricks and breaks Cap's shield in the process.
** Wanda is extremely close to killing Thanos outright, breaking his sword and crushing him in his own armor, but him raining fire on the battlefield takes her out of the fight.
** Finally, Carol manages to fight Thanos to a stalemate, outright {{No Sell}}s his headbutt, and nearly breaks his gauntlet hand, before he knocks her out with the raw power of the Power Stone.
* CutTheSafetyRope: Clint and Natasha's fight over [[MoreExpendableThanYou who gets to die so the other may get the Soul Stone]] ends this way: Clint is saved from falling using Natasha's safety rope, with Natasha holding only one of his hands. [[HeroicSuicide And then she lets go of his hand.]]
