History AvengersEndgame / TropesAToC

* 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.

** Harley Keener, the kid from ''Iron Man 3'', makes a reappearance at Tony Stark's funeral.

*** '''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).

** 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'' (Reality & Mjölnir), and so on. While there are likely some major and irrevocable changes, this will mitigate some of them a great deal.

** 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/{{Doctor Strange|2016}}'', 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/{{Black Panther|2018}}''.

* 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.

*** 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.

** 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.

** 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.

* 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.

* AndIMustScream: Averted. Upon hearing that Scott went into the Quantum Realm just before the Snap, Natasha muses that it must've been torture for him to be trapped down there for five years and wonders how he managed to stay sane. [[spoiler:Scott reveals that to him, [[YearOutsideHourInside it was only five hours]]]].

* 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.

* BusCrash: According to the Russos, both [[Film/TheIncredibleHulk2008 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.

* 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.
** 2014's Thanos snaps after learning that despite achieving his goal of bringing balance to the universe and [[UtopiaJustifiesTheMeans sacrificing everything to accomplish it]], far from being appreciated for his efforts, the entire universe reviles and hates him as a mass-murdering monster, and will pursue ''any'' opportunity of undoing his work. The realisation leads Thanos to conclude his only option is to destroy the universe and create a new one that will appreciate his efforts.

** 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!

* 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.

* CrapsackWorld: Zigzagged. After Thanos wiped out half of all life, resources and the environment on Earth do bounce back, and 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.

*** Actually even more of a CallBack than that: the place where "New Asgard" is established is the city of Tønsberg, which was previously seen in a flashback in ''Film/ThorTheDarkWorld'' and in the 1940's in ''Film/CaptainAmerica'' and shown to have strong Asgardian connections in those appearances.

** 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]].

* BloodBath: When we are "reintroduced" to 2014 Thanos, he returns to his throne room with his double-bladed sword slung over his shoulder after a yet another triumphant battle, with an odd red glistening over the ''entirity'' of his golden armor... then the stomach-turning realization sinks in that it's because he has been butchering so ''many'' enemies in close combat that he is literally splattered ''from head to toe'' in their blood.

** 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''.

*** ''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.

** 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''.

** Before leaving on the mission that ended with him being frozen for several decades Steve had promised to take Peggy Carter dancing. In the flashback of him explaining where he went to Sam we see the two of them dancing together.

* 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.
** Stellan Skarsgard does not appear in this movie, though Erik Selvig has a blink-and-you-miss-it cameo when his face comes into view on the database of snap victims at the Avengers headquarters.

* 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.

** His comics counterpart is an unrepentant genocidal madman who only sought to conquer the universe and wipe out half of all life to appease his mistress, the literal personification of Death herself. The first film changes his motivation to where he still sought to wipe out half the universe, but made him into a WellIntentionedExtremist who was trying to prevent an overpopulation crisis on every world before it claimed the universe like his own planet was. The Avengers are still out to stop him, but they question his methods of solving the crisis rather than the reasoning as to why he's trying to accomplish it. Then, [[spoiler: when the team encounters a past version of the Mad Titan while trying to undo the damage he caused in ''Endgame'', he decides to wipe out the ''entire'' universe and start over because he believes the universe is ungrateful for his sacrifices, proving he's no better than his comics counterpart.]]
** By the same token, he's shown to genuinely care for his daughters (well, Gamora anyway Nebula [[TheUnfavorite not so much]]), showcasing that, unlike his comics counterpart, who treated his children as tools, he is capable of love. [[spoiler: It brings him to tears when he's forced to sacrifice Gamora for the Soul Stone, as he doesn't want to kill her, but [[IveComeTooFar he can't give up his goals for her sake]]. '''Before Thor kills him, he''' also admits to Nebula that he treated her too harshly.]]

* ApocalypseHow: The film shows the aftermath of the Snap at the end of ''Infinity War''. Even worse, [[spoiler:once an AlternateTimeline[='s=] past version of Thanos becomes aware of what's happened in the main timeline's present, he goes there and he seeks to this time use the Infinity Stones to inflict a ApocalypseHow/ClassX4 and then remake the universe InTheirOwnImage]].

** Hulk. He is actually taken out of the picture before the movie even begins, thanks to Banner developing a way to take over the body, denying any closure for his trauma in the past movie. His strength is useless through the movie; as first the Ancient One sidesteps him entirely by punching the astral conscience of Banner out, and then he [[spoiler:is too damaged by the snap to join the final battle]]. When they go back to New York's invasion, his past self is thoroughly mocked, including by Banner himself. He's shown to be left out of the elevator and forced to take the stairs by the other Avengers, and eventually is the reason the plan fails and Loki manages to escape with the Tesseract. Banner doesn't fare much better himself, though, as his intelligence becomes an InformedAttribute, and his attempts at time travel only serve to provide some comic relief (leading to Scott's aforementioned ButtMonkey status) and to underline just how badly the heroes need Tony.
