History AvengersEndgame / TropesAToC

** 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 thrauma in the past movie. His strenght is useless through the movie, as first the Ancient One sidesteps 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 is self, is 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 Locky 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.

** When Thor fights Thanos, Thanos catches Stormbreaker, but Thor tries to force the blade towards him. Captain America jumps on Thanos's back, grabs the axe, and pulls it towards Thanos.

* 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.

** 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.

** 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.

** Tony absently refers to Doctor Strange as the "[[Literature/SherlockHolmes Bleecker Street]] Magician" at the beginning of the film. The actor who plays Doctor Strange (Creator/BenedictCumberbatch) played the title character in ''Series/{{Sherlock}}'', an in-joke made even more ironic since Creator/RobertDowneyJr also played Sherlock in ''Film/{{Sherlock Holmes|2009}}'' and ''Film/SherlockHolmesAGameOfShadows''. Elsewhere in the film, Robert Downey Jr. starred with another actor who played Sherlock Holmes, Creator/JamesDArcy, who played Edwin Jarvis, played Sherlock in Film/{{SherlockCaseOfEvil}}. Interestingly, Stephen Strange's address 177A Bleecker came from the comic book and [[https://www.cbr.com/whats-the-origin-of-dr-stranges-address/ was not a direct reference to Sherlock]].

* 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.

** At the beginning of ''Film/IronMan'', Tony poses with a soldier for a photo. As the soldier flashes a peace sign, Tony sarcastically quips, "Yay, peace, I'd be out of job if it were for peace." In ''Endgame'', when Tony reunites with Steve at the Avengers Compound, he flashes a peace sign and tells Steve, "I just want peace. Turns out resentment is corrosive and I hate it." This shows his final evolution from a weapons contractor to a man opposed to war.

* AnachronismStew: In 2012, Sitwell is seen using a Galaxy S7 phone, which wasn't released until 2016.

* AndIMustScream: Averted. Upon hearing that Scott went into the microverse 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 minutes]]]].

* AbortedArc: The Sokovia Accords are totally unmentioned throughout the movie (though its immediate chronological successor ''Series/WandaVision'' establishes that they’re still around), Steve Rogers and his allies are no longer fugitives, and Hulk is able to operate in public to the point where he poses for selfies with kids. Justified due to how the Snap broke Earth's ruling bodies -- Nick Fury and Maria Hill are gone (so probably no SHIELD), Thaddeus Ross is gone, and we're told world governments are in pieces. It seems like the Avengers are the ones filling the power vacuum of keeping peace and order across the planet, so presumably no one else has the means to bring legal action against them, and if they do then they'd probably not because they need their help now.

* 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.

** Alan Silvestri’s piece “This Is My Choice” played over Steve’s HeroicSacrifice in ''The First Avenger'', as he made the choice that ultimately led to him being frozen and ending up in the future, paving the way for his time as an Avenger. Silvestri reprises much of the track for “Go Ahead”, used for the scene in which Steve has returned from time travel as an old man at the end of his life and career as a superhero, and passes on the mantle of Captain America to Sam.
** Black Widow's first and last chronological appearances in movies both have a main character struggling with alcoholism. Tony in ''Film/IronMan2'' and Thor in this one.

* 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]], and figures she’s just another person who he took a loved one from but doesn’t remember.

** What are Tony Stark's 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.]]

** 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 or didn’t even recognize him since it had been six years since he was last seen and Simpkins has grown quite a bit.

* 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 starts getting hints of a serious tone again as 2014 Thanos uncovers the Avengers’ plan, and finally whiplashes back to serious during it’s final segment - Black Widow's sacrifice.

** Howard the Duck can be seen in the background during the final battle.
