History AvengersEndgame / TropesAToC

* BrokenAesop: Steve Rogers hosts a support group for people who lost loved ones to the genocide of Thanos. He tells them that loss is a natural part of life and that sooner or later one needs to start moving forward, using his own loss of Peggy Carter as an example. At the end of the film when the Avengers have perfected the science behind time travel, Steve goes back and reunites with a young and living Peggy. So in other words Steve's whole viewpoint is dictated entirely by his options.

*** Tony Stark being reluctant to call his hug to Peter at the start of ''Homecoming'' a hug, comes back when he unambiguously hugs him.

* 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.

* 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 didn't GoMadFromTheIsolation. [[spoiler:Scott reveals that to him, [[YearOutsideHourInside it was only five hours]]]].

* 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 seemingly died. [[spoiler:The latter was proven wrong by ''Series/TheFalconAndTheWinterSoldier]]''.

* CollapsibleHelmet: Beyond the usual suspects from previous movies (Ant-Man, Iron Man, War Machine, [[spoiler:Black Panther, Spider-Man, Star-Lord, The Wasp, Captain Marvel, and the unusual ones like Pepper Potts in her "Rescue" armor]]), 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 [[MarqueeAlterEgo to show their faces at almost all times]], except when the helmets are an absolute necessity, i.e. during trips in the Quantum Realm. Owing to the difficulty of applying this trope to users with long hair, in the case of Thor once more having long hair and now a shaggy beard as well, the movie cheats by only showing him with helmet either already on or off, never forming like the others. Likewise with Rocket, due to being an enhanced raccoon.

* 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.

* 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 seemingly died. [[spoiler:the latter was proven wrong by ''Series/TheFalconAndTheWinterSoldier]]''.

** Cap and Bucky repeat their "Don't do anything stupid til I get back" banter from ''Film/CaptainAmericaTheFirstAvenger'', only with their roles reversed.
** When present-day Cap is fighting 2012 Cap, the latter says: "I could do this all day." This was essentially his catchphrase in the first Captain America film, which present-Cap wryly acknowledges.

** 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".
*** 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/{{Thor}}'' and in the 1940's in ''Film/CaptainAmerica'' and shown to have strong Asgardian connections in those appearances.

** 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.

** 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.

** 2014 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 realization leads Thanos to conclude his only option is to destroy the universe and create a new one that will appreciate his efforts.

** 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.

** When Sam Wilson shows up for the final fight, he announces himself to Cap by saying "On your left," which Cap said several times to him during ''Film/CaptainAmerica TheWinterSoldier''.

** When the team have Thanos restrained at the beginning of the movie, Thor decapitates him. His response when asked "what did you do"?

* 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.
