* SadisticChoice: Six characters are forced to choose between saving one person important to them and (by obtaining or not giving in an Infinity Stone) saving half the universe. Three of them choose the former: Loki and Gamora refuse to sacrifice their siblings (Thor and Nebula) as an ActOfTrueLove, and Doctor Strange won't let his ally Tony Stark die as a part of a BatmanGambit. All the chosen persons are spared by Thanos and survive the Snap. Other three characters decide to [[KillTheOnesYouLove Kill the Ones They Love]]: Peter Quill and Wanda attempt to kill their romantic partners at their request, but it is AllForNothing because Thanos won't let them proceed and murders the victims anyway, and Thanos himself tosses his daughter off the cliff to get the Soul Stone.

----
!!!''Film/AvengersInfinityWar'' provides examples of the following tropes:
[[foldercontrol]]
!'''Spoilers for ''all'' Franchise/MarvelCinematicUniverse movies, including this one, will be left unmarked. Administrivia/YouHaveBeenWarned!'''
[[folder:S]]
* SacrificialLion: The first onscreen characters killed by Thanos are ''Thor'' mainstays Heimdall and Loki, establishing that Thanos is ruthless and will stop at nothing to gather the Stones.
* SadClown: Much of the humor in the film has a dark undertone to it as the characters realize how much trouble they are in, but no one gets hit worse than Thor. Following the events of Ragnarok, he lost his father (his mother died a few years ago), his planet, nearly all of his friends, and most of his people. This movie starts with most of the rest of his people, his brother and one of his last friends killed by Thanos. He keeps trying to make jokes, but they keep becoming more and more strained. Rocket confronts him about it, and Thor admits that his life is at its worst right now, but insists that Thanos is going to end up dead just like every other enemy he has fought in the past fifteen hundred years. It's clear that he's trying to convince himself more than Rocket.
* SanityStrengthening: Time on Vormir for more than a human lifetime has given Johann Schmidt time to calm down from his AxCrazy persona previously shown. This isn't to say he's no longer evil by any stretch, but he is calm and rational when speaking about the Soul Stone, apparently having come to terms with the fact that he will never have it himself. In all he comes across as a RetiredMonster.
* SarcasmBlind: Rocket, being his usual snarky self, calls Star-Lord and the rest of the Guardians "morons". Thor, not knowing the group's name, then sincerely says "I bid you good luck and farewell, Morons," when he, Rocket, and Groot leave for Nidavellir.
* SawItInAMovieOnce: When saving Doctor Strange from Ebony Maw on the spaceship, Peter Parker suggests to [[ThrownOutTheAirlock space]] the latter, "like in that movie ''Aliens''."
* ScrewTheRulesImDoingWhatsRight: Secretary Ross ignores the fact Earth is being assaulted by aliens in favor of the fugitive Avengers being spotted and, using his authority under the Sokovia Accords, orders Rhodey to arrest them. Rhodey, understanding that the aliens are an actual threat to humanity and Ross is being petty and short-sighted, realizes that the Accords as they are aren't a good thing and refuses to do it. Ross issues him a court-martial (which Rhodey ignores) and Rhodey reconciles with his comrades so they can fight together.
* ScrewThisImOuttaHere: Thor arrives to Wakanda with the Stormbreaker and mows down a bunch of Outriders. They are so terrified of him that they begin to flee.
* SecretTestOfCharacter: A twisted version given to the hero by ''the villain.'' When Thanos captures Gamora, she begs Peter Quill to kill her as he'd promised to. Rather than disabling Star-Lord as he had Drax and Mantis, Thanos actually holds Gamora right in front of his gun and tells him to do it. What initially seems like another case of [[EvilCannotComprehendGood a villain mistakenly assuming that]] LoveIsAWeakness by assuming that Peter's love for Gamora makes him too weak to stop Thanos, instead turns out to be a test of Star-Lord's willpower -- when he pulls the trigger, Thanos has already used the Reality Stone to disarm his gun, causing it to shoot harmless bubbles, but he still [[VillainRespect earns Thanos's respect]] for actually being willing to do it.
-->'''Thanos:''' I like you.
* SeenItAll: The MCU as a whole has reached a point where people just take crazy things in stride.
** The [[Creator/StanLee bus driver]] is unperturbed about an alien ship that is frightening the students on his bus.
** Tony is more surprised by [[SkewedPriorities seeing Banner again]] than he is by Doctor Strange's sudden introduction via a magic portal.
** Tony also doesn't bother questioning how he's meeting another human being from Earth on a distant planet, accompanied by a blue alien and a yellow-ish alien with antennae.
** Peter Parker doesn't even question or blink an eye at Tony summing up the situation as, "He's from space. He came here to steal a necklace from a wizard."
** Steve's reaction to meeting Groot for the first time is to simply and politely introduce himself.
** Likewise, Bucky seems similarly nonchalant about fighting back-to-back with a gun-toting raccoon, only telling him that he won't sell him his gun or metal arm when asked.
** Even Rhodey, whose [[Film/IronMan3 last]] [[Film/AvengersAgeOfUltron three]] [[Film/CaptainAmericaCivilWar appearances]] had him flabbergasted at fire-breathing villains, flying intangible androids, and Giant-Man, doesn't stop to question things like Thor showing up with a gun-toting raccoon and a talking tree this time.
* SenselessSacrifice: Vision sacrifices himself by letting Wanda destroy his Mind Stone, ensuring that Thanos can't acquire it and complete his Infinity Stone collection. She succeeds, but Thanos uses the Time Stone to completely rewind Vision's body exploding, and rips it out of his head intact (essentially forcing Vision to die twice).
* SequelEscalation: The movie has the largest cast in an MCU movie, features the biggest threat established up until this point, and is split into two parts to tell the whole story. It also has the ''highest'' death toll out of every film.
* SequelHook: In the post-credits scene, just as Nick Fury is turning into ashes, he drops his pager which is flashing "sending" before displaying the heraldry of none other than Film/{{Captain Marvel|2019}}.
* SequelReset: The Guardians have dialed back a couple to their old status quo since 2. When last seen they were using the remaining quadrant of the Ravager ship with Kraglin. Now they are in a similar ship and Kraglin is nowhere to be seen. Two years have gone by, after all.
* SeriesFauxnale: While the film and its sequel will serve as the GrandFinale for the narrative carried through the first three Phases of films in the MCU, it will be far from the last movie in the setting -- in fact, the sequel to ''Film/SpiderManHomecoming'' in 2019 and three 2020 release dates for Marvel-related movies were reserved by Sony and Disney before this even began filming. Furthermore, several actors in the MCU [[note]]namely, Sebastian Stan (Winter Soldier/White Wolf), Benedict Cumberbatch (Doctor Strange), Chadwick Boseman (Black Panther), Chris Pratt (Star-Lord), and Tom Holland (Spider-Man)[[/note]] have stated that their contracts will unlikely be fulfilled by ''Infinity War'' and its sequel.
* ShaggyDogStory: All attempts at stopping Thanos mean nothing in the end, as he gets what he wants. For the unlucky, this crosses into ShootTheShaggyDog because the cosmic fingersnap kills them.
** Cap, Black Widow, Banner, Scarlet Witch, Bucky, Falcon, War Machine, T'Challa and the entirety of Wakanda try to HoldTheLine on Thanos's forces to give Shuri time to extract the Mind Stone from Vision without killing him. Thanos just walks through ''all'' of them after the heroes have repelled his {{Mooks}}, forcing Wanda to kill Vision by destroying the Stone, which is ultimately also for naught as Thanos just rewinds time to rebuild it and personally kills Vision himself to get the Stone.
** Iron Man, Spider-Man, Doctor Strange, and the Guardians attack Thanos on Titan to surprise him and take the gauntlet from him. This fails once Quill learns of Gamora's death, ruining the plans and leading to their inevitable fates.
** Thor, Rocket, and Groot help Eitri build a new weapon for Thor. While Thor with Stormbreaker is indeed powerful enough to kill Thanos, his shot ends up being not fatal ''enough'', giving Thanos the opportunity to complete his plan.
* ShapedLikeItself: This exchange between Thor and Eitri, after Thor decides to hold open a forge powered by a star:
-->'''Eitri:''' It will kill you.\\
'''Thor:''' Only if I die.\\
'''Eitri:''' ''[puzzled]'' Yes. That's what killing you means.
* ShooOutTheClowns: Of the heroes that Thanos dusts with the Infinity Gauntlet or personally kills, five of the twelve are members of the Guardians of the Galaxy, leaving only Nebula and Rocket (neither of whom were the most comical of the group) left out of them. In addition, the notably wisecracking Peter Parker is among the casualties. Given the DownerEnding that this movie leaves off on, there probably won't be much room for levity in the sequel.
* ShootTheBuilder: Played with. Thanos forces King Eitri and his dwarves to make the Infinity Gauntlet for him, then kills them all leaving Eitri the SoleSurvivor. But first he makes Eitri put his hands in molten metal so he can't forge weapons against him. "Your life is yours," he said. "But your hands... Your hands are mine alone."
* ShootTheHostage: After Thanos has taken Gamora hostage at Knowhere, she demands Peter to shoot her to prevent Thanos from getting information regarding the Soul Stone's location from her. Peter eventually comply but Thanos turns his shots into bubbles, averting this trope.
* ShoutOut:
** When Iron Man first goes up against Ebony Maw, he refers to him as "[[WesternAnimation/SpongeBobSquarePants Squidward]]". In the French version, he instead calls him [[Franchise/HarryPotter Voldemort]].
** Iron Man and Spider-Man blast a hole in Ebony Maw's ship and he's hurled into space, a deliberate Shout-Out to ''Film/{{Alien}}'', where the titular alien is killed in the same manner. During the scuffle on Titan, when Spider-Man encounters Mantis, he freaks out because he thinks she's going to lay eggs in him à la facehugger.
** Thanos is referred to as "[[UsefulNotes/McDonalds Grimace]]" by Peter Quill.
* ShutUpHannibal: Stark interrupts Ebony Maw's UtopiaJustifiesTheMeans spiel with a "Get lost, [[WesternAnimation/SpongebobSquarepants Squidward]]!"
* SickeningCrunch: There is a very unsettling cracking sound when Thanos breaks Loki's neck.
* SilenceIsGolden: Downplayed during the climax after Thanos snaps his fingers and disintegrates 50% of the universe's population, as the entire sequence takes place without any background music, though ambient sounds and dialogue are still present, they are all quiet in order to drive home the impact of what just happened.
* SinsOfOurFathers: {{Subverted}} -- when Thor is told that Gamora is Thanos's daughter, he angrily exclaims that her father killed his brother and seems to be about to attack her. But when Quill tells him that Gamora hates Thanos just as much as he does, Thor ceases and sympathizes with her instead.
* SkewedPriorities: Secretary Ross. Despite the fact that the Earth is under attack from a major alien threat, and has just lost one of its greatest defenders (Tony Stark), he refuses to even entertain the idea of accepting help from the fugitive heroes, instead ordering James Rhodes to arrest them.
* SlowMotionFall: Gamora's death, when Thanos throws her off the cliff on Vormir to get the Soul Stone, is played out slowly to add the gravitas of the scene.
* SlowNo: Gamora refuses to be Thanos's sacrifice in the same frame-rate and for the same reason as the SlowMotionFall.
* TheSmurfettePrinciple:
** The Children of Thanos, of which Proxima Midnight is the only female member (Supergiant was AdaptedOut, and Nebula and Gamora have long since defected from the group and their family).
** After Gamora is taken by Thanos, Mantis is the only female Guardian, even when they join up with Iron Man, Spider-Man, and Doctor Strange on Titan. This is ultimately subverted when the actual battles comes, as Nebula -- the reason the Guardians are on Titan at all -- becomes their EleventhHourRanger.
** Generally averted with the rest of the movie; there're at least two women in each team (excepting the above mentioned example), from when Scarlet Witch and Vision reunite with the Secret Avengers on.
* SnarkToSnarkCombat:
** Tony Stark and Stephen Strange (initially) don't get along and throw jabs at each other.
--->'''Doctor Strange:''' [Thanos] could destroy life on a scale hitherto undreamt of.\\
'''Tony Stark:''' Did you seriously just say "hitherto undreamt of"?\\
'''Doctor Strange:''' Are you seriously leaning on the Cauldron of the Cosmos?\\
'''Tony Stark:''' ''[still leaning]'' Is that what this--\\
''[the Cloak of Levitation slaps Stark]''\\
'''Tony Stark:''' ''[puzzled]'' I'm going to allow that.
** This escalates even further when they meet Peter Quill.
* SnowMeansDeath: On the snowy mountains of Vormir, Thanos hurls Gamora off a cliff as a sacrifice for the Soul Stone. It is a cold and ruthless act, but it reveals a hitherto unrecognized warmth in the Mad Titan's heart.
* SoleSurvivor: After Thanos's fingersnap turns half of the universe's population to dust, Rocket is the only surviving member of the Guardians of the Galaxy.
* SomeKindOfForceField: Although the domed force field over Wakanda City is already visible as a faint blue glow, Proxima Midnight tests it out with the tip of her sword, making it brightly crackle, while awaiting Captain America and Black Panther for a face-off.
* SoMuchForStealth: On Knowhere, Peter Quill, Gamora, Drax, and Mantis are trying to sneak up on Thanos, but Drax wants to attack him right away. Right before he can charge and give away their position, Mantis makes him fall asleep. The unconscious Drax falls forward with a loud thud, giving them away.
* SorryThatImDying: Peter Parker's dying words to Tony Stark are "I'm sorry."
* SpaceIsCold: Ebony Maw's demise is to be ThrownOutTheAirlock and freeze in an instant in space.
* SparedByTheAdaptation: Captain America and Iron Man survive their encounters with Thanos, unlike the original story.
* SpecialEditionTitle: Unlike most of the previous films' opening Marvel logos, the typical fanfare is replaced by the sounds of a distress call placed by the Asgardian ship seen at the end of ''Film/ThorRagnarok'', along with the "I" and "O" in ''Marvel Studios'' being replaced with the number 10 to mark the MCU's anniversary.
* SpiderLimbs: Spider-Man's new nanomachine-constructed suit is the MCU's version of the Iron Spider armor, and thus it has four spider-like legs sprouting out of his back when needed. Note that Peter doesn't know about them since he's surprised when they first come out to prevent him from being sucked out the Q-ship by decompression.
* SpiderSense:
** Visually shown in a scene with Peter Parker on a bus ride, after only being implied in previous installments. When it kicks in, we can tell by the fact that the hairs on his arm suddenly stick up.
** In a much darker moment, Peter's Spider-Sense kicks off just before he realizes that he's about to die after Thanos's snap.
* SpiritualSuccessor:
** The film has been called the MCU equivalent to the ''Film/RogueOne'' with the high death count of named heroes at the hands of the villain.
** It's also been compared to ''Film/TheEmpireStrikesBack'', given how it concludes on an unambiguously DownerEnding with [[TheBadGuyWins the bad guy winning.]]
** The fingersnap scene has been called by many people to be the Marvel Cinematic Universe's equivalent to the [[NastyParty Red Wedding]] in ''Series/GameOfThrones'', as several beloved heroic characters die in rapid succession with [[TheBadGuyWins the villain coming out triumphant]]. Coincidentally, Creator/PeterDinklage who plays Tyrion in the show is also present in the movie as Eitri.
* SpoilerCover: The poster has two of the Infinity Stones already in the Gauntlet: purple/Power (Thanos already has it in the opening scene) and blue/Space (where he gets that one by breaking the Tesseract).
* SpontaneousWeaponCreation: Iron Man's new armor is made of nanomachines, and one of their many applications is to let him create a wide variety of weapons throughout the film, from knives to cannons to missile launchers.
* StakingTheLovedOne: [[StrangeMindsThinkAlike Both Vision and Gamora]] request their respective lovers, Wanda and Peter, to kill them to prevent Thanos from reaching his goals.
* StandardFemaleGrabArea: Justified, since Thanos is much bigger and stronger than Gamora and she is weaponless. Grabbing her by the arm is effective in his case.
* StatusQuoIsGod:
** After losing his eye and his hammer in ''Film/ThorRagnarok'', Thor gets replacements for both in this film, although the first is robotic and the second has significant upgrades.
** This is zig-zagged overall as nearly all the New Avengers -- Vision, Scarlet Witch, Falcon, Spider-Man, Black Panther, and Doctor Strange -- and nearly all the Guardians -- Gamora, Star-Lord, Drax, Mantis, and Groot -- are killed (War Machine and Rocket are the two respective exceptions), but all the Original Avengers -- Iron Man, Captain America, Thor, Hulk, and Black Widow -- survive (though Nick Fury and Maria Hill are killed in TheStinger, and Hawkeye's fate is unknown).
* StealthPun: The car Nick Fury and Maria Hill are in during TheStinger is an Infiniti [=QX50=].
* StevenUlyssesPerhero: Lampshaded by Peter Parker when he and Doctor Strange introduce themselves; Peter thinks that "Doctor Strange" is the "made up name", and so he reintroduces himself as Spider-Man.
* TheStinger: Maria Hill and Nick Fury are disintegrated along with half of all life in the universe, but not before the latter drops a S.H.I.E.L.D. issue pager with a [[Film/CaptainMarvel2019 mysterious heraldry flashing across its screen]], summoning the aid of an unknown group of heroes to join in for the battle of the DarkestHour in the Franchise/MarvelCinematicUniverse.
* StockholmSyndrome: Gamora is distraught when she thinks she's killed Thanos, to the latter's surprise as she's made no secret of her hatred for him. Despite his troops murdering half her planet and likely her mother as well, Thanos has reared her as a ParentalSubstitute and is shown to have genuine love for her.
* StockScream: Ebony Maw uses the Wilhelm Scream when vented into outer space.
* StrongButUnskilled: Hulk is so absurdly powerful that he usually doesn't need any particular strategy beyond brute strength. His fight with Thanos is over within a minute in part because Thanos is equally strong, but shows much more skill such as defensive posturing and attacking weak spots. Up until then, [[TheWorfEffect no-one even knew Hulk had weak spots]].
* SuddenlyAlwaysKnewThat: Thor is capable of understanding Groot's PokemonSpeak. He apparently picked it up as an elective during his education. This may actually be a joke; it's never been clarified one way or the other whether MCU Asgardians maintain their [[TranslatorMicrobes Allspeak]] ability from the comics or are actually just speaking English.
* SuddenSequelDeathSyndrome: The first twenty minutes almost completely overwrite the ending of ''Film/ThorRagnarok'', as it begins with the Asgardian ship under attack and a large number of people either dead or being massacred. Heimdall dies moments after transporting Bruce back to Earth, while Loki bites it a couple minutes later in a failed ruse (especially notable considering he was the most prominent villain who ''always'' escaped death beforehand); neither Valkyrie, Korg or Miek appear and their statuses are currently unknown (though WordOfGod from Joe Russo later confirmed Valkyrie at least survived). A short while later, the Guardians discover that the Collector is dead on Knowhere.
* SupermanStaysOutOfGotham:
** Ant-Man and Hawkeye are nowhere to be seen in this film. A throwaway line reveals they're under house arrest after taking plea deals to be with their families instead of in the Raft or constantly on the run.
** Captain Marvel is not present to help the rest of the heroes. Only her insignia is seen on Fury's pager in the stinger, alerting her, wherever she is, that Earth needs her.
* SuperpowerLottery: The Infinity Gauntlet, when fully assembled, effectively allows its wielder to do '''anything''': [[PersonOfMassDestruction blow up planets with a touch]], [[TimeMaster control the flow of time]], [[RealityWarper reshape reality]], [[SoulPower enter a dimension of souls]], {{mind control}} anyone, {{teleport|ation}} anywhere instantly, [[PhysicalGod you name it]].
* SurprisinglySuddenDeath: Thanos's "death" at the hands of Gamora is done in two cuts and an EtTuBrute moment from Thanos. It's lampshaded by Quill with a "That was quick." Of course, it's followed up by the revelation that Thanos already took the Reality Stone and was just luring the Guardians there so he could find Gamora.
* SurroundedByIdiots: At one point, Tony gives a ThousandYardStare after putting up with Star-Lord, Spider-Man, Drax and Mantis's collective SkewedPriorities long enough.
* SurvivorGuilt: Thor has shades of this, since he believes that the only reason he has survived so far is because fate wills it so and that he's the one destined to kill Thanos. Mantis also states that Thor is feeling immense guilt, although it has [[BigBrotherInstinct other reasons]] as well.
* SympathyForTheHero:
** In a heart-felt moment, Thanos honestly tells Tony Stark, who has failed to stop him, "I hope they remember you." Apparently, Thanos has been inside his head for some time and understands his struggles as well as admires his determination.
** After witnessing Wanda destroy the Mind Stone and Vision along with it, Thanos takes a moment to tell her he knows how she feels and even gives her an AffectionateGestureToTheHead.
[[/folder]]
[[folder:T]]
* TakeAThirdOption: Steve tries to find a way to stop Thanos from getting the Mind Stone without forcing the Scarlet Witch to kill Vision. In the end she has to kill him anyway, and even that doesn't work.
* TakesOneToKillOne: Vision realizes that since Wanda gained her powers after being experimented on by HYDRA with Loki's sceptre, she is the only one who can destroy the Mind Stone since her powers were a byproduct of it. Indeed, Wanda's powers seem to be the only thing capable of destroying one of the Infinity Stones.
* TearsOfRemorse: Shed by Thanos when he learns that he needs to kill his beloved adopted daughter, Gamora, in order to continue his quest.
* TeethClenchedTeamwork: For the heroes on Titan, how else could the two {{Insufferable Genius}}es that are Tony Stark and Stephen Strange, the AnnoyingYoungerSibling type Peter Parker and Peter Quill the {{Troll}}, work together? The first two can't stand each other because of their egos and antithetic fields of work, and the latter two just annoy the hell out of Stark and Strange either unwillingly, or pretty much willingly in the case of Quill. Amazingly, they come the closest to defeating Thanos.
* TeleportSpam: On Titan, Doctor Strange creates portals left and right, which the other heroes use to attack Thanos and try to keep him off guard.
* TemptingFate: T'Challa's last words to Okoye before he is disintegrated by the power of the Gauntlet are an encouraging "This is no place to die!"
* ThanatosGambit: Strange uses the Time Stone to examine millions of possible scenarios, and only finds one where the heroes succeed. At the end, as he's disintegrating, he tells Tony that even his death is AllAccordingToPlan. We never heard the one successful scenario, so UnspokenPlanGuarantee may be in effect.
* ThemeMusicAbandonment: During the Marvel Studios title card, the triumphal theme doesn't play. Instead, we slowly start to hear the DistressCall from the Asgardian refugees.
* ThemeMusicPowerUp:
** The Avengers theme plays triumphantly when Captain America, Black Widow, and Falcon save Wanda and Vision from Corvus Glaive and Proxima Midnight.
** The theme pops up again later when Thor, Rocket, and Groot [[BigDamnHeroes make their entrance during the battle against the Outriders]].
--->'''Bruce Banner:''' [[LampshadeHanging You guys are so screwed now!]]
* TheyCalledMeMad: Thanos says he was called this in the past because of how he wanted to solve his planet's OverpopulationCrisis, which he felt would otherwise lead to their extinction. Considering his solution was killing half the population, this reaction was justified, even if he ended up being right about their fate.
* ThisCannotBe: After the Red Skull tells Thanos and Gamora that one must sacrifice someone they truly love in order to gain the Soul Stone, Gamora takes a moment to gloat, [[WrongGenreSavvy thinking that the Soul Stone would forever be out of Thanos's reach]]. The Keeper then helps Gamora realize that Thanos ''did'' love someone -- '''her'''. Gamora's expression becomes one of utter disbelief and horror as Thanos hurls her over a cliff, allowing him to acquire the Soul Stone.
* ThreePointLanding: Iron Man naturally does his iconic landing as his one-on-one fight with Thanos himself begins.
* ThresholdGuardians: The Soul Stone is watched over by a still-alive Red Skull, who spells out to Thanos the sacrifice he has to make in order to retrieve it. And yes, it is unusual for this trope to apply to the ''villain'' of the story rather than the hero, but again Thanos is very much the VillainProtagonist here, and he certainly believes he has a heroic goal.
* ThrownOutTheAirlock: Done explicitly as a ShoutOut to ''Film/{{Alien}}''; Iron Man and Spider-Man open a hole in the spaceship's hull that sucks Ebony Maw into space, saving Strange in the process.
* TimePassageBeard: Steve Rogers sports a beard indicating that he's been on the run and underground since ''Civil War''.
* TitleIn: The film introduces different locations around the universe with white text on-screen, including "[[CaptainObvious SPACE]]" when the camera cuts to the Guardians's ship.
* TogetherInDeath: Thanos kills Gamora and Vision at different points in the film. At the end, two of the victims of his BadassFingersnap are their lovers (Peter Quill and Wanda Maximoff, respectively), allowing them to be this, though whether all of these characters stay dead for good remains to be seen.
* TonightSomeoneDies: The film's marketing campaign made it clear early on that not every hero that goes into ''Infinity War'' was going to make it out alive... aside from a few characters like Spider-Man and the Guardians who were confirmed to have future films in production. Which was actually a swerve, as nearly ''every'' character with future films die, while most of the now out-of-contract actors, like the original Avengers cast, make it out of this film and must now resolve everything.
* TookALevelInBadass:
** Spidey has gotten ''far'' more competent in the two years since his last solo outing, successfully fighting off Cull Obsidian and Ebony Maw during the fight in New York, both of them being very powerful ''and'' willing to kill him. He then gets a [[PowerArmor suit upgrade]], courtesy of Tony, which enables him to participate in the group battle against Thanos himself and even get a few solid licks in on the guy who curb-stomped ''the Hulk''.
** Doctor Strange becomes a far more competent fighter since his debut film due to all the time he's had to practice the Mystical Arts since then.
** Thor gets a ''massive'' power spike when [[InfinityPlusOneSword Stormbreaker]] is forged.
** Iron Man's nano-tech suit gives a wide variety of abilities he's never had before and greatly enhances the powers he already had, allowing him to fight Thanos briefly. Notably, he's one of only two characters in the film to draw Thanos's blood (the other is Thor while wielding Stormbreaker).
** With Hulk refusing to show up, Banner himself picks up the slack by piloting the Hulkbuster armor in the Wakanda battle. He manages to be pretty effective in it, despite being inexperienced. He says it is like being the Hulk without actually being the Hulk.
* TooMuchAlike: Tony Stark and Stephen Strange share a strong mutual dislike of the other, primarily because they're both InsufferableGenius {{Deadpan Snarker}}s who are evenly matched in both capacities.
* TragicMistake:
** Stark, Strange, Drax, and Parker have Thanos (barely) immobilized after much effort, with Mantis managing to mentally incapacitate the Titan enough to allow the aforementioned heroes to slowly wrestle the Infinity Gauntlet from him; had Quill not struck the tyrant's head in a mad fit of grief and rage for Gamora's murder, throwing off the focus of Mantis's hypnotism, half the universe would not have had to die on that day. Of course, that's assuming Thanos wouldn't have been able to get the gauntlet back anyway, which given Strange's implication this outcome was the one GoldenPath out of 14 million, he would have.
** When Thor strikes Thanos with Stormbreaker, he hits him in the chest so he can look him in the eye and tell him that he would have made him pay for what he had done. Thanos proceeds to use the last of his strength to snap his fingers, killing off half of the universe's population and also healing himself and teleporting away. As Thanos points out, Thor should have aimed for his head but he wanted to gloat to him so badly that this mistake cost the heroes victory. According to the Russo brothers, this mistake is on par with Star-Lord's.
* TranslationConvention:
** Thanks to the translator implants carried by each member of the Guardians of the Galaxy (sans Groot, of course), there are no barriers to communication between them and the English-speaking Avengers. Regardless of which character is speaking and where, other characters and the audience will understand everything that is being said.
** Handwaved when the Guardians pick up Thor, who, surprisingly, can understand Groot. "Groot" was an elective course in schools on Asgard.
* TrickedOutGloves: The Infinity Gauntlet is a gold-plated glove built to hold six different reality-warping artifacts at once, making the wielder omnipotent when complete.
* TheTriple:
-->'''Peter Quill:''' I'm gonna ask you this one time: where's Gamora?\\
'''Tony Stark:''' Yeah, I'll do you one better: WHO'S Gamora?\\
'''Drax:''' I'll do YOU one better: WHY is Gamora?
* TryToFitThatOnABusinessCard: Loki introduces himself to Thanos as "Loki, prince of Asgard, Odinson, the rightful king of Jötunnheim, God of Mischief."
* TurnTheOtherCheek: Even though Vision was directly (if accidentally) responsible for turning Colonel Rhodes into a cripple who cannot even stand (much less walk) without bionics crafted by Stark attached to him 24-hours a day, when the Android returns to the Avengers Headquarters mortally wounded, he greeted him with open arms, and ignoring orders to arrest the Captain Faction, offered his wholehearted support to help him extract the Mind Stone from his forehead to save his life.

[[folder:U]]
* UncertainDoom: Pepper Potts, Ned Leeds, May Parker, Cindy Moon, Sally Avril, Tiny [=McKreever=], Thunderbolt Ross, Eitri the King Dwarf, Red Skull, Wong, and Shuri are not shown in the ending, so their fates are not revealed in the film itself. For that matter, the fates of any and all MCU characters not present in the movie (from Ant-Man and Hawkeye to Korg and Miek from ''Thor: Ragnarok'' to Kraglin Obfonteri and the Ravager clans from the ''Guardians of the Galaxy'' trilogy to the Netflix characters) are not known at this time, either. The Russo Brothers later confirmed which characters are alive, dead, or too spoilery to state. Lady Sif and Betty Ross are dead, Aunt May and Howard The Duck are alive, and the fates of Korg, Miek, Jane Foster, Ned Leeds, Pepper Potts, Valkyrie, and Shuri are massive spoilers.
* {{Understatement}}: PlayedForDrama. Captain America is left so utterly (and understandably) stunned by Thanos using the Infinity Stones to literally kill half the universe, that his only response is a quiet, affectless "Oh, God."
* UnspokenPlanGuarantee: Hinted at; the exact details of the plan to attack Thanos on Titan and take the Gauntlet from him are not disclosed to the audience, but although that plan ultimately fails, after Strange stated that he would be willing to let Tony and Peter die to protect the Time Stone and handed it over to Thanos anyway, coupled with his last words of "There was no other way", it suggests that Strange actually ''planned'' for the battle to turn out that way....
* UpgradeArtifact: Whereas Mjölnir was actually a PowerLimiter for Thor's lightning powers, Stormbreaker is this and ''enhances'' his powers.
* UpToEleven: Everything that has accumulated throughout the MCU up to this film is brought to bear against Thanos in the ultimate battle to protect the universe from his tyranny. All creative and filmic aspects are this as well. The story is the biggest one yet, the most serious of any Marvel movie to date, and the cast (of ''62 characters'') is the biggest of any superhero film ever.
%%
%% Unexpected Character is now a YMMV item, put all examples on the YMMV page.
%%
* UseYourHead: Thanos rams his head against Iron Man's helmet during their fight on Titan.
* UtopiaJustifiesTheMeans: Thanos intends to kill half the universe to solve the problem of limited resources and overpopulation. This, he says, will ensure that everyone is prosperous, "a full belly and clear skies" as he puts it. He succeeds horribly.
[[/folder]]
[[folder:V]]
* VillainProtagonist: Similar to his depiction in ''The Infinity Gauntlet'', Thanos is unquestionably the central character of ''Infinity War''. The film explores his backstory and motivations, giving him sympathetic qualities and a meaty dramatic arc. Every other character arc or beat (such as Tony Stark facing his fears, Gamora dealing with her familiar feelings, and Thor grieving for his friends and family) exists in the orbit of Thanos. This is particularly felt when after the post-credits scene, it is announced that ''Thanos'' will return rather than the Avengers.
-->'''Kevin Feige:''' Thanos in ''Infinity War'' is, you know, in a movie that has [[LoadsAndLoadsOfCharacters a lot of characters]], you could almost go so far as to say he is the main character, and that's a bit of a departure from what we've done before, but that was appropriate for a movie called ''Infinity War''.
* VillainRespect:
** Thanos says "I like him" of Quill when Quill proves willing (after much hesitation) to kill Gamora if it means keeping the Soul Stone out of Thanos's hands. He doesn't actually let Quill kill Gamora, of course, but appreciates his resolve.
** Openly declared to Tony Stark by Thanos for his futile but courageous final stand against him; the tyrant even sincerely wishes that the people of Earth will remember him for his heroism.
** Silently done, when Thanos begins his march in Wakanda to the final Stone defeating every hero with one hand; Captain America not only blocks his path twice, but is capable of holding the Mad Titan powered by ''five'' Infinity Stones back, which should be impossible. This earns him a smile of approval from Thanos as he uses both hands to beat Cap back.
** In a broad sense, Thanos shows proper respect to many of the heroes, including the above-mentioned three. He uses only brute force on The Hulk instead of the Power Stone to give Hulk a chance. He trades words of philosophy with Doctor Strange with no hostility, truly trying to make the wizard understand his motives. He is actually impressed Wanda had the will to kill Vision (her lover) to keep the Mind Stone from him. Finally, he's also impressed that Thor can severely wound him when he gains all the Infinity Stones. All in all, he truly means it when he says he's trying to be unbiased and fair in his crusade.
* ViolentlyProtectiveGirlfriend: Wanda for Vision when they're attacked by Proxima and Corvus. She repeatedly blasts them away from Vision when they try to take the Mind Stone from him, refuses to leave when he asks her (for her own safety) to do so, and prepares to take them both on by herself until [[BigDamnHeroes Cap and his team show up]]. Which just makes it all the more tragic when she's forced to kill him by destroying the Mind Stone despite all her efforts to protect him. And when she sees Thanos about to kill Vision again, she furiously lunges at him, only to be blown back.
[[/folder]]
[[folder:W]]
* WalkInChimeIn: T'Challa promises Steve and his group that they will fight alongside the full strength of Wakanda's military, and Bucky appears, commenting, "...and a semi-stable hundred-year-old man".
* WasItReallyWorthIt: When Thanos assembles the Infinity Stones and succeeds in killing half the universe, he's visited by a vision of Gamora as a child, asking what he had to sacrifice to achieve his goal. Thanos's answer?
-->'''Thanos:''' ''... Everything.''
* WeHaveReserves: Black Panther says that the invaders will get nothing in Wakanda with "dust and blood". Proxima Midnight replies that "we have blood to spare" as she reveals heaps of alien troops. Who then hurl themselves at the shield, getting burned and dismembered until some of them finally make it through intact.
* WellIntentionedExtremist: Thanos wants to cull the universe of half of its population because he thinks that overpopulation will eventually lead to even ''more'' people dying and a completely unnecessary amount of suffering to boot. Why? Because that's exactly what happened to Thanos's homeplanet of Titan when he stepped away from doing what was "right" the first time.
* WeNeedADistraction: When Peter Parker's SpiderSense activates on the school bus and he sees a Q-ship in the distance, he taps Ned's face and asks him to create a distraction. Ned immediately enthusiastically shouts "We're all gonna die!", herding the rest of the kids to the back of the bus. Whether or not Ned actually heard Peter or saw the ship and panicked on his own doesn't matter, since Peter got his chance to leave the bus unnoticed.
* WhamEpisode: Without question, the biggest one in the MCU. Most of our heroes are dead and there's no clear way to undo the massive amount of damage that Thanos has done to the Universe.
* WhamLine: Several.
** The Earth-based heroes' first encounter with the Children of Thanos. When Bruce tries HulkingOut like Tony suggested...
--->'''Hulk:''' ''[[BigNo NOOOO!!!]]''
** Gamora is held captive by Thanos, and he says he sent her on a mission to find the only Infinity Stone unaccounted-for. And he knows she ''didn't'' fail.
** Perhaps the biggest is when the Red Skull tells Thanos and Gamora that to get the Soul Stone, Thanos must "sacrifice that which he loves the most." Gamora laughs that Thanos loves nothing as he turns to look at her.
--->'''Gamora:''' Tears? Really?\\
'''Red Skull:''' They are not [[EvenEvilHasLovedOnes for him]].
** When Thor runs Thanos through the chest with Stormbreaker.
--->'''Thanos:''' You should have gone for the head. ''[snap]''
** A particularly heartbreaking one as Thanos succeeds in wiping out half of the universe's population, and the audience is wondering which of their heroes they're gonna watch die next:
--->'''Peter Parker:''' Mr. Stark? I don't feel so good.
* WhamShot:
** The guardian of the Soul Stone is none other than a still-alive ComicBook/RedSkull.
** T'Challa holds the relatively expendable Okoye's hand as the audience expects her to die, only to see T'Challa, a character presumed immortal due to his popularity, crumble to ash.
** As usual, TheStinger provides one where Nick Fury tries to send a distress signal before he gets disintegrated. The symbol that appears on his communicator resembles that of [[Film/CaptainMarvel2019 Carol Danvers']] costume.
* WhatHappenedToTheMouse:
** Wong mentions that he's going back to protect the Sanctum after Strange is kidnapped as Tony and Peter go after him. His fate is not known as of the end of the film and the fingersnap.
** Hawkeye and Ant-Man never appear in the movie. It's mentioned that they've gone back to their families; their fates (and that of their families') after Thanos wiped out half of the universe's population are not revealed, either.
** Valkyrie, Korg and Miek are nowhere to be seen as Thanos storms the Asgardian ship and lays waste to apparently everyone on board. Director Joe Russo confirmed that Valkyrie at least survived after the film's release. In the film itself, it is mentioned repeatedly that Thanos kills half of the people and lets the remaining half live; thus, it can be inferred that half of the Asgardian/Sakaarian refugees aboard survived.
* WhatMeasureIsAMook: On the one hand, the heroes display clear horror at the casual disregard the Children of Thanos have for their "soldiers'" lives. On the other hand, while Cap tells Vision they "don't trade lives" he seems to have no problem risking the lives of hundreds of Wakandan soldiers to buy time for Vision.
* WhatMeasureIsANonHuman: For heroes that usually go for ThouShaltNotKill, facing HumanAliens erase any qualms about that, such as Spider-Man creating the plan that sends Ebony Maw into space.
* WhatTheHellHero:
** Tony Stark tells Bruce Banner that (due to the events of ''Film/CaptainAmericaCivilWar'') he won't contact Steve Rogers despite Thanos's imminent arrival because the two are not on speaking terms, prompting Banner to question this reasoning and later call Rogers himself.
** Eitri is really unhappy to see Thor, saying "You were supposed to protect us. Asgard was supposed to protect us!" Thor explains that Asgard was destroyed.
** Tony is distraught at Strange giving up the Time Stone and asks "Why did you do that!?" Like Thor, Strange is able to a give good answer why, which shuts Tony up.
* WhoAreYou: Thor asks, "Who the hell are you guys?" after he wakes up on the Guardians' ship.
* WhoNamesTheirKidDude: Upon hearing Stephen Strange introduce himself as "Doctor Strange", Peter Parker responds "Oh, we're using our made-up names. Then, I am Spider-Man." Strange doesn't even bother clearing it up.
* WillReturnCaption: The film ends with a "Thanos will return" caption, which then crumbles to dust.
* WizardDuel:
** Doctor Strange and Ebony Maw engage in one in New York, and Strange loses. Although since a spell prevents Maw from just seizing the necklace, he takes Strange prisoner and brings him on his ship.
** Doctor Strange vs. Thanos wielding four Infinity Stones. They throw energy beams at each other, Strange creates two dozen copies of himself which Thanos dispels, and so on.
* TheWorfBarrage: During his LastStand against Thanos, Iron Man unleashes several old and new weapons in his suit, weapons that had defeated many enemies before and even hurt the {{big bad}}s of the previous Avengers movies. He uses everything in his arsenal, to the point of almost completely exhausting his nano-machine supply, and all he gets for his effort is "a drop of blood."
* TheWorfEffect:
** Thor is beaten offscreen by Thanos before the movie even starts, meaning our villain is introduced dragging the God of Thunder's limp body around like a doll so you know he won't be taking any prisoners.
** Hulk gets beaten handily during the opening sequence just to drive home how unstoppable Thanos is. Ebony Maw even prevents the Children of Thanos from fighting Hulk just so Thanos "can have his fun," and Thanos seemingly takes him on without the aid of the Gauntlet's power and purely his own strength.
** The first scene has Thanos already holding an Infinity Stone -- the Power Stone, which was under the protection of the [[Film/GuardiansOfTheGalaxy Nova Corps on Xandar]], meaning he had already taken it by force. Thor later confirms it, letting us know all of Xandar was decimated in order to demonstrate that yes, Thanos is strong.
* WorldOfSnark: If you thought every MCU movie before featured droll wit, you ain't seen nothing yet because they all come together into one big ball of it in this film, considering it combines Creator/TaikaWaititi's humour from ''Film/ThorRagnarok'', Creator/JamesGunn's humour [[Film/GuardiansOfTheGalaxy from both]] [[Film/GuardiansOfTheGalaxyVol2 films of the Guardians]], and the tendency of the MCU as a whole to give even the darkest, most stoic characters at least a single moment of snark. Then again, given the [[DarkerAndEdgier nature of the film]], the moments ''are'' few and far between.
* WorthyOpponent: Thanos grows to respect Stark, both for their similarity in being "cursed with knowledge" and for his, Stark's, LastStand. Tony himself is shocked when Thanos addresses him by name.
* WoundThatWillNotHeal: Vision gets impaled by Corvus's spear which is capable of injuring him even in intangible form. While he manages to survive, he spends the rest of the movie incapacitated.
* WreckedWeapon: After Thanos snaps his finger with all the Stones installed and wipes out half the life in the universe, the gauntlet looks charred and cracked. It's not clarified if the gauntlet is actually damaged or hindered in its abilities (Thanos easily teleports away afterwards), but the impression is the same.
* WrestlerInAllOfUs: Thanos bodyslams Hulk as a finishing move and later, choke slams Spider-Man.
[[/folder]]
[[folder:Y-Z]]
* YankTheDogsChain:
** The movie is particularly cruel to Wanda, who spends the majority of the movie trying to find a way to destroy the Mind Stone without killing Vision. After an intense battle on Wakanda, as Thanos approaches the couple, Wanda finally decides to destroy the Mind Stone, killing Vision in a particularly painful manner. While she succeeds, Thanos simply reverses time to restore Vision and his Mind Stone only to rip the Infinity Stone off of Vision.
** Tony, Doctor Strange, and the rest of the Guardians ''finally'' manage to ''almost'' slip the Gauntlet off of Thanos's hand, but [[NiceJobBreakingItHero Star-Lord lets his anger get the best of him and unsurprisingly screws up the entire mission.]]
** The Asgardians had narrowly escaped extinction when their home planet was destroyed in order to kill a mad goddess. Not long into their exodus, their already dwindling population have decreased in half when Thanos attacked their ship. Then, according to WordOfGod that Lady Sif was among those killed by Thanos's culling, half of ''those'' was decreased by half.
** Armed with Stormbreaker, Thor '''almost''' manages to kill Thanos with a blow to the chest... only for Thanos to survive long enough to snap his fingers.
* YouAreNotAlone: Natasha says this near-verbatim about Wanda to Proxima Midnight, when Proxima is seconds from killing Wanda, relishing in her about to die without her lover by her side.
-->'''Proxima Midnight:''' He'll die alone, as will you.\\
'''Black Widow:''' She's not alone.
* YouAreTooLate:
** The Guardians of the Galaxy pick up the distress signal from Asgardians' ''Statesman'' but by the time they arrive, the ''Statesman'' is already destroyed and there's no survivor except Thor.
** Quill, Gamora, Mantis, and Drax head to Knowhere to obtain the Reality Stone before Thanos can. When they arrive, they find he's already there, trying to torture the Stone's location out of the Collector. Gamora attacks and seemingly manages to kill him, only for everything to wash away, revealing that Knowhere has been completely trashed and Thanos already has the Stone.
* YouCantFightFate:
** Thanos is apparently a firm believer in this trope, as he gives the aforementioned "Destiny arrives all the same" speech.
--->'''Thanos:''' Dread it. Run from it. Destiny arrives all the same.
** Thor strongly believes that fate has commanded him to kill Thanos, or else the deaths of Odin, Frigga, Hela, Loki, the Warriors Three, Heimdall, and half the Asgardians would have been for naught.
* YouCantThwartStageOne:
** The film has this feel early on. When Gamora warns that Thanos gaining the Reality Stone in addition to the Space and Power Stones already in his possession will make him too powerful to stop, Thor bluntly replies that he already is.
** It wouldn't be an ''Infinity Gauntlet'' adaptation without it. Thanos gathers all the Infinity Stones and, despite Thor ''running him through'' with Stormbreaker, wipes out half of all sapient life. The surviving heroes are left to pick up the pieces and somehow make things right in the sequel.
* YouHaveNoChanceToSurvive: The Children of Thanos enjoy likening the Avengers' attempts to fight back to parlor tricks and that all is lost for the glory of Thanos.
* YoureInsane: Gamora to Thanos, when he tells her that he genuinely believes that he helped her planet by slaughtering half of its people.
* YoureNotMyFather: Gamora to Thanos, when he repeatedly calls her his daughter.
* YourOtherLeft: When Thanos is about to discover the Guardians on Knowhere, Quill tells Gamora to go to the right, but she goes left instead, prompting Quill to utter exasperatedly, "Your ''other'' right!"
* YouTalkTooMuch: During the opening, Thanos has just slaughtered half of Asgard and beaten Thor bloody, and is holding him by the head, but Thor still isn't impressed by his grandstanding.
-->'''Thanos:''' Destiny arrives all the same. And now it's here... or should I say, I am.\\
'''Thor:''' You talk too much.
* YouWouldntShootMe: Subverted. Gamora convinces Quill to promise to kill her if she's captured by Thanos. When he does capture her, Thanos taunts Quill into shooting her, which he does... only for the Mad Titan to turn the gun and its laser blast into bubbles.
* ZergRush: The Outriders have massive numbers on their side and charge against the Avengers and the Wakandans. Several of them manage to [[DogPileOfDoom take down the Hulkbuster armor, dragging it to the ground]].

* SadClown: Much of the humor in the film has a dark undertone to it as the characters realize how much trouble they are in, but no one gets hit worse than Thor. Following the events of Ragnarok, he lost his father (his mother died a few years ago), his planet, nearly all of his friends, and most of his people. This movie starts with most of the rest of his people, his brother and one of his last friends killed by Thanos. He keeps trying to make jokes, but they keep becoming more and more strained. Rocket confronts him about it, and Thor admits that his life is at its worst right now, but insists that Thanos is going to end up dead just like every other enemy he has fought in the past fifteen hundred years. It's clear that he's trying to convince himself more than Rocket.
* SanityStrengthening: Time on Vormir for more than a human lifetime has given Johann Schmidt time to calm down from his AxCrazy persona previously shown. This isn't to say he's no longer evil by any stretch, but he is calm and rational when speaking about the Soul Stone, apparently having come to terms with the fact that he will never have it himself. In all he comes across as a RetiredMonster.
* SarcasmBlind: Rocket, being his usual snarky self, calls Star-Lord and the rest of the Guardians "morons". Thor, not knowing the group's name, then sincerely says "I bid you good luck and farewell, Morons," when he, Rocket, and Groot leave for Nidavellir.
* SawItInAMovieOnce: When saving Doctor Strange from Ebony Maw on the spaceship, Peter Parker suggests to [[ThrownOutTheAirlock space]] the latter, "like in that movie ''Aliens''."
* ScrewTheRulesImDoingWhatsRight: Secretary Ross ignores the fact Earth is being assaulted by aliens in favor of the fugitive Avengers being spotted and, using his authority under the Sokovia Accords, orders Rhodey to arrest them. Rhodey, understanding that the aliens are an actual threat to humanity and Ross is being petty and short-sighted, realizes that the Accords as they are aren't a good thing and refuses to do it. Ross issues him a court-martial (which Rhodey ignores) and Rhodey reconciles with his comrades so they can fight together.
* ScrewThisImOuttaHere: Thor arrives to Wakanda with the Stormbreaker and mows down a bunch of Outriders. They are so terrified of him that they begin to flee.
* SecretTestOfCharacter: A twisted version given to the hero by ''the villain.'' When Thanos captures Gamora, she begs Peter Quill to kill her as he'd promised to. Rather than disabling Star-Lord as he had Drax and Mantis, Thanos actually holds Gamora right in front of his gun and tells him to do it. What initially seems like another case of [[EvilCannotComprehendGood a villain mistakenly assuming that]] LoveIsAWeakness by assuming that Peter's love for Gamora makes him too weak to stop Thanos, instead turns out to be a test of Star-Lord's willpower -- when he pulls the trigger, Thanos has already used the Reality Stone to disarm his gun, causing it to shoot harmless bubbles, but he still [[VillainRespect earns Thanos's respect]] for actually being willing to do it.
-->'''Thanos:''' I like you.
* SeenItAll: The MCU as a whole has reached a point where people just take crazy things in stride.
** The [[Creator/StanLee bus driver]] is unperturbed about an alien ship that is frightening the students on his bus.
** Tony is more surprised by [[SkewedPriorities seeing Banner again]] than he is by Doctor Strange's sudden introduction via a magic portal.
** Tony also doesn't bother questioning how he's meeting another human being from Earth on a distant planet, accompanied by a blue alien and a yellow-ish alien with antennae.
** Peter Parker doesn't even question or blink an eye at Tony summing up the situation as, "He's from space. He came here to steal a necklace from a wizard."
** Steve's reaction to meeting Groot for the first time is to simply and politely introduce himself.
** Likewise, Bucky seems similarly nonchalant about fighting back-to-back with a gun-toting raccoon, only telling him that he won't sell him his gun or metal arm when asked.
** Even Rhodey, whose [[Film/IronMan3 last]] [[Film/AvengersAgeOfUltron three]] [[Film/CaptainAmericaCivilWar appearances]] had him flabbergasted at fire-breathing villains, flying intangible androids, and Giant-Man, doesn't stop to question things like Thor showing up with a gun-toting raccoon and a talking tree this time.
* SenselessSacrifice: Vision sacrifices himself by letting Wanda destroy his Mind Stone, ensuring that Thanos can't acquire it and complete his Infinity Stone collection. She succeeds, but Thanos uses the Time Stone to completely rewind Vision's body exploding, and rips it out of his head intact (essentially forcing Vision to die twice).
* SequelEscalation: The movie has the largest cast in an MCU movie, features the biggest threat established up until this point, and is split into two parts to tell the whole story. It also has the ''highest'' death toll out of every film.
* SequelHook: In the post-credits scene, just as Nick Fury is turning into ashes, he drops his pager which is flashing "sending" before displaying the heraldry of none other than Film/{{Captain Marvel|2019}}.
* SequelReset: The Guardians have dialed back a couple to their old status quo since 2. When last seen they were using the remaining quadrant of the Ravager ship with Kraglin. Now they are in a similar ship and Kraglin is nowhere to be seen. Two years have gone by, after all.
* SeriesFauxnale: While the film and its sequel will serve as the GrandFinale for the narrative carried through the first three Phases of films in the MCU, it will be far from the last movie in the setting -- in fact, the sequel to ''Film/SpiderManHomecoming'' in 2019 and three 2020 release dates for Marvel-related movies were reserved by Sony and Disney before this even began filming. Furthermore, several actors in the MCU [[note]]namely, Sebastian Stan (Winter Soldier/White Wolf), Benedict Cumberbatch (Doctor Strange), Chadwick Boseman (Black Panther), Chris Pratt (Star-Lord), and Tom Holland (Spider-Man)[[/note]] have stated that their contracts will unlikely be fulfilled by ''Infinity War'' and its sequel.
* ShaggyDogStory: All attempts at stopping Thanos mean nothing in the end, as he gets what he wants. For the unlucky, this crosses into ShootTheShaggyDog because the cosmic fingersnap kills them.
** Cap, Black Widow, Banner, Scarlet Witch, Bucky, Falcon, War Machine, T'Challa and the entirety of Wakanda try to HoldTheLine on Thanos's forces to give Shuri time to extract the Mind Stone from Vision without killing him. Thanos just walks through ''all'' of them after the heroes have repelled his {{Mooks}}, forcing Wanda to kill Vision by destroying the Stone, which is ultimately also for naught as Thanos just rewinds time to rebuild it and personally kills Vision himself to get the Stone.
** Iron Man, Spider-Man, Doctor Strange, and the Guardians attack Thanos on Titan to surprise him and take the gauntlet from him. This fails once Quill learns of Gamora's death, ruining the plans and leading to their inevitable fates.
** Thor, Rocket, and Groot help Eitri build a new weapon for Thor. While Thor with Stormbreaker is indeed powerful enough to kill Thanos, his shot ends up being not fatal ''enough'', giving Thanos the opportunity to complete his plan.
* ShapedLikeItself: This exchange between Thor and Eitri, after Thor decides to hold open a forge powered by a star:
-->'''Eitri:''' It will kill you.\\
'''Thor:''' Only if I die.\\
'''Eitri:''' ''[puzzled]'' Yes. That's what killing you means.
* ShooOutTheClowns: Of the heroes that Thanos dusts with the Infinity Gauntlet or personally kills, five of the twelve are members of the Guardians of the Galaxy, leaving only Nebula and Rocket (neither of whom were the most comical of the group) left out of them. In addition, the notably wisecracking Peter Parker is among the casualties. Given the DownerEnding that this movie leaves off on, there probably won't be much room for levity in the sequel.
* ShootTheBuilder: Played with. Thanos forces King Eitri and his dwarves to make the Infinity Gauntlet for him, then kills them all leaving Eitri the SoleSurvivor. But first he makes Eitri put his hands in molten metal so he can't forge weapons against him. "Your life is yours," he said. "But your hands... Your hands are mine alone."
* ShootTheHostage: After Thanos has taken Gamora hostage at Knowhere, she demands Peter to shoot her to prevent Thanos from getting information regarding the Soul Stone's location from her. Peter eventually comply but Thanos turns his shots into bubbles, averting this trope.
* ShoutOut:
** When Iron Man first goes up against Ebony Maw, he refers to him as "[[WesternAnimation/SpongeBobSquarePants Squidward]]". In the French version, he instead calls him [[Franchise/HarryPotter Voldemort]].
** Iron Man and Spider-Man blast a hole in Ebony Maw's ship and he's hurled into space, a deliberate Shout-Out to ''Film/{{Alien}}'', where the titular alien is killed in the same manner. During the scuffle on Titan, when Spider-Man encounters Mantis, he freaks out because he thinks she's going to lay eggs in him à la facehugger.
** Thanos is referred to as "[[UsefulNotes/McDonalds Grimace]]" by Peter Quill.
* ShutUpHannibal: Stark interrupts Ebony Maw's UtopiaJustifiesTheMeans spiel with a "Get lost, [[WesternAnimation/SpongebobSquarepants Squidward]]!"
* SickeningCrunch: There is a very unsettling cracking sound when Thanos breaks Loki's neck.
* SilenceIsGolden: Downplayed during the climax after Thanos snaps his fingers and disintegrates 50% of the universe's population, as the entire sequence takes place without any background music, though ambient sounds and dialogue are still present, they are all quiet in order to drive home the impact of what just happened.
* SinsOfOurFathers: {{Subverted}} -- when Thor is told that Gamora is Thanos's daughter, he angrily exclaims that her father killed his brother and seems to be about to attack her. But when Quill tells him that Gamora hates Thanos just as much as he does, Thor ceases and sympathizes with her instead.
* SkewedPriorities: Secretary Ross. Despite the fact that the Earth is under attack from a major alien threat, and has just lost one of its greatest defenders (Tony Stark), he refuses to even entertain the idea of accepting help from the fugitive heroes, instead ordering James Rhodes to arrest them.
* SlowMotionFall: Gamora's death, when Thanos throws her off the cliff on Vormir to get the Soul Stone, is played out slowly to add the gravitas of the scene.
* SlowNo: Gamora refuses to be Thanos's sacrifice in the same frame-rate and for the same reason as the SlowMotionFall.
* TheSmurfettePrinciple:
** The Children of Thanos, of which Proxima Midnight is the only female member (Supergiant was AdaptedOut, and Nebula and Gamora have long since defected from the group and their family).
** After Gamora is taken by Thanos, Mantis is the only female Guardian, even when they join up with Iron Man, Spider-Man, and Doctor Strange on Titan. This is ultimately subverted when the actual battles comes, as Nebula -- the reason the Guardians are on Titan at all -- becomes their EleventhHourRanger.
** Generally averted with the rest of the movie; there're at least two women in each team (excepting the above mentioned example), from when Scarlet Witch and Vision reunite with the Secret Avengers on.
* SnarkToSnarkCombat:
** Tony Stark and Stephen Strange (initially) don't get along and throw jabs at each other.
--->'''Doctor Strange:''' [Thanos] could destroy life on a scale hitherto undreamt of.\\
'''Tony Stark:''' Did you seriously just say "hitherto undreamt of"?\\
'''Doctor Strange:''' Are you seriously leaning on the Cauldron of the Cosmos?\\
'''Tony Stark:''' ''[still leaning]'' Is that what this--\\
''[the Cloak of Levitation slaps Stark]''\\
'''Tony Stark:''' ''[puzzled]'' I'm going to allow that.
** This escalates even further when they meet Peter Quill.
* SnowMeansDeath: On the snowy mountains of Vormir, Thanos hurls Gamora off a cliff as a sacrifice for the Soul Stone. It is a cold and ruthless act, but it reveals a hitherto unrecognized warmth in the Mad Titan's heart.
* SoleSurvivor: After Thanos's fingersnap turns half of the universe's population to dust, Rocket is the only surviving member of the Guardians of the Galaxy.
* SomeKindOfForceField: Although the domed force field over Wakanda City is already visible as a faint blue glow, Proxima Midnight tests it out with the tip of her sword, making it brightly crackle, while awaiting Captain America and Black Panther for a face-off.
* SoMuchForStealth: On Knowhere, Peter Quill, Gamora, Drax, and Mantis are trying to sneak up on Thanos, but Drax wants to attack him right away. Right before he can charge and give away their position, Mantis makes him fall asleep. The unconscious Drax falls forward with a loud thud, giving them away.
* SorryThatImDying: Peter Parker's dying words to Tony Stark are "I'm sorry."
* SpaceIsCold: Ebony Maw's demise is to be ThrownOutTheAirlock and freeze in an instant in space.
* SparedByTheAdaptation: Captain America and Iron Man survive their encounters with Thanos, unlike the original story.
* SpecialEditionTitle: Unlike most of the previous films' opening Marvel logos, the typical fanfare is replaced by the sounds of a distress call placed by the Asgardian ship seen at the end of ''Film/ThorRagnarok'', along with the "I" and "O" in ''Marvel Studios'' being replaced with the number 10 to mark the MCU's anniversary.
* SpiderLimbs: Spider-Man's new nanomachine-constructed suit is the MCU's version of the Iron Spider armor, and thus it has four spider-like legs sprouting out of his back when needed. Note that Peter doesn't know about them since he's surprised when they first come out to prevent him from being sucked out the Q-ship by decompression.
* SpiderSense:
** Visually shown in a scene with Peter Parker on a bus ride, after only being implied in previous installments. When it kicks in, we can tell by the fact that the hairs on his arm suddenly stick up.
** In a much darker moment, Peter's Spider-Sense kicks off just before he realizes that he's about to die after Thanos's snap.
* SpiritualSuccessor:
** The film has been called the MCU equivalent to the ''Film/RogueOne'' with the high death count of named heroes at the hands of the villain.
** It's also been compared to ''Film/TheEmpireStrikesBack'', given how it concludes on an unambiguously DownerEnding with [[TheBadGuyWins the bad guy winning.]]
** The fingersnap scene has been called by many people to be the Marvel Cinematic Universe's equivalent to the [[NastyParty Red Wedding]] in ''Series/GameOfThrones'', as several beloved heroic characters die in rapid succession with [[TheBadGuyWins the villain coming out triumphant]]. Coincidentally, Creator/PeterDinklage who plays Tyrion in the show is also present in the movie as Eitri.
* SpoilerCover: The poster has two of the Infinity Stones already in the Gauntlet: purple/Power (Thanos already has it in the opening scene) and blue/Space (where he gets that one by breaking the Tesseract).
* SpontaneousWeaponCreation: Iron Man's new armor is made of nanomachines, and one of their many applications is to let him create a wide variety of weapons throughout the film, from knives to cannons to missile launchers.
* StakingTheLovedOne: [[StrangeMindsThinkAlike Both Vision and Gamora]] request their respective lovers, Wanda and Peter, to kill them to prevent Thanos from reaching his goals.
* StandardFemaleGrabArea: Justified, since Thanos is much bigger and stronger than Gamora and she is weaponless. Grabbing her by the arm is effective in his case.
* StatusQuoIsGod:
** After losing his eye and his hammer in ''Film/ThorRagnarok'', Thor gets replacements for both in this film, although the first is robotic and the second has significant upgrades.
** This is zig-zagged overall as nearly all the New Avengers -- Vision, Scarlet Witch, Falcon, Spider-Man, Black Panther, and Doctor Strange -- and nearly all the Guardians -- Gamora, Star-Lord, Drax, Mantis, and Groot -- are killed (War Machine and Rocket are the two respective exceptions), but all the Original Avengers -- Iron Man, Captain America, Thor, Hulk, and Black Widow -- survive (though Nick Fury and Maria Hill are killed in TheStinger, and Hawkeye's fate is unknown).
* StealthPun: The car Nick Fury and Maria Hill are in during TheStinger is an Infiniti [=QX50=].
* StevenUlyssesPerhero: Lampshaded by Peter Parker when he and Doctor Strange introduce themselves; Peter thinks that "Doctor Strange" is the "made up name", and so he reintroduces himself as Spider-Man.
* TheStinger: Maria Hill and Nick Fury are disintegrated along with half of all life in the universe, but not before the latter drops a S.H.I.E.L.D. issue pager with a [[Film/CaptainMarvel2019 mysterious heraldry flashing across its screen]], summoning the aid of an unknown group of heroes to join in for the battle of the DarkestHour in the Franchise/MarvelCinematicUniverse.
* StockholmSyndrome: Gamora is distraught when she thinks she's killed Thanos, to the latter's surprise as she's made no secret of her hatred for him. Despite his troops murdering half her planet and likely her mother as well, Thanos has reared her as a ParentalSubstitute and is shown to have genuine love for her.
* StockScream: Ebony Maw uses the Wilhelm Scream when vented into outer space.
* StrongButUnskilled: Hulk is so absurdly powerful that he usually doesn't need any particular strategy beyond brute strength. His fight with Thanos is over within a minute in part because Thanos is equally strong, but shows much more skill such as defensive posturing and attacking weak spots. Up until then, [[TheWorfEffect no-one even knew Hulk had weak spots]].
* SuddenlyAlwaysKnewThat: Thor is capable of understanding Groot's PokemonSpeak. He apparently picked it up as an elective during his education. This may actually be a joke; it's never been clarified one way or the other whether MCU Asgardians maintain their [[TranslatorMicrobes Allspeak]] ability from the comics or are actually just speaking English.
* SuddenSequelDeathSyndrome: The first twenty minutes almost completely overwrite the ending of ''Film/ThorRagnarok'', as it begins with the Asgardian ship under attack and a large number of people either dead or being massacred. Heimdall dies moments after transporting Bruce back to Earth, while Loki bites it a couple minutes later in a failed ruse (especially notable considering he was the most prominent villain who ''always'' escaped death beforehand); neither Valkyrie, Korg or Miek appear and their statuses are currently unknown (though WordOfGod from Joe Russo later confirmed Valkyrie at least survived). A short while later, the Guardians discover that the Collector is dead on Knowhere.
* SupermanStaysOutOfGotham:
** Ant-Man and Hawkeye are nowhere to be seen in this film. A throwaway line reveals they're under house arrest after taking plea deals to be with their families instead of in the Raft or constantly on the run.
** Captain Marvel is not present to help the rest of the heroes. Only her insignia is seen on Fury's pager in the stinger, alerting her, wherever she is, that Earth needs her.
* SuperpowerLottery: The Infinity Gauntlet, when fully assembled, effectively allows its wielder to do '''anything''': [[PersonOfMassDestruction blow up planets with a touch]], [[TimeMaster control the flow of time]], [[RealityWarper reshape reality]], [[SoulPower enter a dimension of souls]], {{mind control}} anyone, {{teleport|ation}} anywhere instantly, [[PhysicalGod you name it]].
* SurprisinglySuddenDeath: Thanos's "death" at the hands of Gamora is done in two cuts and an EtTuBrute moment from Thanos. It's lampshaded by Quill with a "That was quick." Of course, it's followed up by the revelation that Thanos already took the Reality Stone and was just luring the Guardians there so he could find Gamora.
* SurroundedByIdiots: At one point, Tony gives a ThousandYardStare after putting up with Star-Lord, Spider-Man, Drax and Mantis's collective SkewedPriorities long enough.
* SurvivorGuilt: Thor has shades of this, since he believes that the only reason he has survived so far is because fate wills it so and that he's the one destined to kill Thanos. Mantis also states that Thor is feeling immense guilt, although it has [[BigBrotherInstinct other reasons]] as well.
* SympathyForTheHero:
** In a heart-felt moment, Thanos honestly tells Tony Stark, who has failed to stop him, "I hope they remember you." Apparently, Thanos has been inside his head for some time and understands his struggles as well as admires his determination.
** After witnessing Wanda destroy the Mind Stone and Vision along with it, Thanos takes a moment to tell her he knows how she feels and even gives her an AffectionateGestureToTheHead.
[[/folder]]
[[folder:T]]
* TakeAThirdOption: Steve tries to find a way to stop Thanos from getting the Mind Stone without forcing the Scarlet Witch to kill Vision. In the end she has to kill him anyway, and even that doesn't work.
* TakesOneToKillOne: Vision realizes that since Wanda gained her powers after being experimented on by HYDRA with Loki's sceptre, she is the only one who can destroy the Mind Stone since her powers were a byproduct of it. Indeed, Wanda's powers seem to be the only thing capable of destroying one of the Infinity Stones.
* TearsOfRemorse: Shed by Thanos when he learns that he needs to kill his beloved adopted daughter, Gamora, in order to continue his quest.
* TeethClenchedTeamwork: For the heroes on Titan, how else could the two {{Insufferable Genius}}es that are Tony Stark and Stephen Strange, the AnnoyingYoungerSibling type Peter Parker and Peter Quill the {{Troll}}, work together? The first two can't stand each other because of their egos and antithetic fields of work, and the latter two just annoy the hell out of Stark and Strange either unwillingly, or pretty much willingly in the case of Quill. Amazingly, they come the closest to defeating Thanos.
* TeleportSpam: On Titan, Doctor Strange creates portals left and right, which the other heroes use to attack Thanos and try to keep him off guard.
* TemptingFate: T'Challa's last words to Okoye before he is disintegrated by the power of the Gauntlet are an encouraging "This is no place to die!"
* ThanatosGambit: Strange uses the Time Stone to examine millions of possible scenarios, and only finds one where the heroes succeed. At the end, as he's disintegrating, he tells Tony that even his death is AllAccordingToPlan. We never heard the one successful scenario, so UnspokenPlanGuarantee may be in effect.
* ThemeMusicAbandonment: During the Marvel Studios title card, the triumphal theme doesn't play. Instead, we slowly start to hear the DistressCall from the Asgardian refugees.
* ThemeMusicPowerUp:
** The Avengers theme plays triumphantly when Captain America, Black Widow, and Falcon save Wanda and Vision from Corvus Glaive and Proxima Midnight.
** The theme pops up again later when Thor, Rocket, and Groot [[BigDamnHeroes make their entrance during the battle against the Outriders]].
--->'''Bruce Banner:''' [[LampshadeHanging You guys are so screwed now!]]
* TheyCalledMeMad: Thanos says he was called this in the past because of how he wanted to solve his planet's OverpopulationCrisis, which he felt would otherwise lead to their extinction. Considering his solution was killing half the population, this reaction was justified, even if he ended up being right about their fate.
* ThisCannotBe: After the Red Skull tells Thanos and Gamora that one must sacrifice someone they truly love in order to gain the Soul Stone, Gamora takes a moment to gloat, [[WrongGenreSavvy thinking that the Soul Stone would forever be out of Thanos's reach]]. The Keeper then helps Gamora realize that Thanos ''did'' love someone -- '''her'''. Gamora's expression becomes one of utter disbelief and horror as Thanos hurls her over a cliff, allowing him to acquire the Soul Stone.
* ThreePointLanding: Iron Man naturally does his iconic landing as his one-on-one fight with Thanos himself begins.
* ThresholdGuardians: The Soul Stone is watched over by a still-alive Red Skull, who spells out to Thanos the sacrifice he has to make in order to retrieve it. And yes, it is unusual for this trope to apply to the ''villain'' of the story rather than the hero, but again Thanos is very much the VillainProtagonist here, and he certainly believes he has a heroic goal.
* ThrownOutTheAirlock: Done explicitly as a ShoutOut to ''Film/{{Alien}}''; Iron Man and Spider-Man open a hole in the spaceship's hull that sucks Ebony Maw into space, saving Strange in the process.
* TimePassageBeard: Steve Rogers sports a beard indicating that he's been on the run and underground since ''Civil War''.
* TitleIn: The film introduces different locations around the universe with white text on-screen, including "[[CaptainObvious SPACE]]" when the camera cuts to the Guardians's ship.
* TogetherInDeath: Thanos kills Gamora and Vision at different points in the film. At the end, two of the victims of his BadassFingersnap are their lovers (Peter Quill and Wanda Maximoff, respectively), allowing them to be this, though whether all of these characters stay dead for good remains to be seen.
* TonightSomeoneDies: The film's marketing campaign made it clear early on that not every hero that goes into ''Infinity War'' was going to make it out alive... aside from a few characters like Spider-Man and the Guardians who were confirmed to have future films in production. Which was actually a swerve, as nearly ''every'' character with future films die, while most of the now out-of-contract actors, like the original Avengers cast, make it out of this film and must now resolve everything.
* TookALevelInBadass:
** Spidey has gotten ''far'' more competent in the two years since his last solo outing, successfully fighting off Cull Obsidian and Ebony Maw during the fight in New York, both of them being very powerful ''and'' willing to kill him. He then gets a [[PowerArmor suit upgrade]], courtesy of Tony, which enables him to participate in the group battle against Thanos himself and even get a few solid licks in on the guy who curb-stomped ''the Hulk''.
** Doctor Strange becomes a far more competent fighter since his debut film due to all the time he's had to practice the Mystical Arts since then.
** Thor gets a ''massive'' power spike when [[InfinityPlusOneSword Stormbreaker]] is forged.
** Iron Man's nano-tech suit gives a wide variety of abilities he's never had before and greatly enhances the powers he already had, allowing him to fight Thanos briefly. Notably, he's one of only two characters in the film to draw Thanos's blood (the other is Thor while wielding Stormbreaker).
** With Hulk refusing to show up, Banner himself picks up the slack by piloting the Hulkbuster armor in the Wakanda battle. He manages to be pretty effective in it, despite being inexperienced. He says it is like being the Hulk without actually being the Hulk.
* TooMuchAlike: Tony Stark and Stephen Strange share a strong mutual dislike of the other, primarily because they're both InsufferableGenius {{Deadpan Snarker}}s who are evenly matched in both capacities.
* TragicMistake:
** Stark, Strange, Drax, and Parker have Thanos (barely) immobilized after much effort, with Mantis managing to mentally incapacitate the Titan enough to allow the aforementioned heroes to slowly wrestle the Infinity Gauntlet from him; had Quill not struck the tyrant's head in a mad fit of grief and rage for Gamora's murder, throwing off the focus of Mantis's hypnotism, half the universe would not have had to die on that day. Of course, that's assuming Thanos wouldn't have been able to get the gauntlet back anyway, which given Strange's implication this outcome was the one GoldenPath out of 14 million, he would have.
** When Thor strikes Thanos with Stormbreaker, he hits him in the chest so he can look him in the eye and tell him that he would have made him pay for what he had done. Thanos proceeds to use the last of his strength to snap his fingers, killing off half of the universe's population and also healing himself and teleporting away. As Thanos points out, Thor should have aimed for his head but he wanted to gloat to him so badly that this mistake cost the heroes victory. According to the Russo brothers, this mistake is on par with Star-Lord's.
* TranslationConvention:
** Thanks to the translator implants carried by each member of the Guardians of the Galaxy (sans Groot, of course), there are no barriers to communication between them and the English-speaking Avengers. Regardless of which character is speaking and where, other characters and the audience will understand everything that is being said.
** Handwaved when the Guardians pick up Thor, who, surprisingly, can understand Groot. "Groot" was an elective course in schools on Asgard.
* TrickedOutGloves: The Infinity Gauntlet is a gold-plated glove built to hold six different reality-warping artifacts at once, making the wielder omnipotent when complete.
* TheTriple:
-->'''Peter Quill:''' I'm gonna ask you this one time: where's Gamora?\\
'''Tony Stark:''' Yeah, I'll do you one better: WHO'S Gamora?\\
'''Drax:''' I'll do YOU one better: WHY is Gamora?
* TryToFitThatOnABusinessCard: Loki introduces himself to Thanos as "Loki, prince of Asgard, Odinson, the rightful king of Jötunnheim, God of Mischief."
* TurnTheOtherCheek: Even though Vision was directly (if accidentally) responsible for turning Colonel Rhodes into a cripple who cannot even stand (much less walk) without bionics crafted by Stark attached to him 24-hours a day, when the Android returns to the Avengers Headquarters mortally wounded, he greeted him with open arms, and ignoring orders to arrest the Captain Faction, offered his wholehearted support to help him extract the Mind Stone from his forehead to save his life.

[[folder:U]]
* UncertainDoom: Pepper Potts, Ned Leeds, May Parker, Cindy Moon, Sally Avril, Tiny [=McKreever=], Thunderbolt Ross, Eitri the King Dwarf, Red Skull, Wong, and Shuri are not shown in the ending, so their fates are not revealed in the film itself. For that matter, the fates of any and all MCU characters not present in the movie (from Ant-Man and Hawkeye to Korg and Miek from ''Thor: Ragnarok'' to Kraglin Obfonteri and the Ravager clans from the ''Guardians of the Galaxy'' trilogy to the Netflix characters) are not known at this time, either. The Russo Brothers later confirmed which characters are alive, dead, or too spoilery to state. Lady Sif and Betty Ross are dead, Aunt May and Howard The Duck are alive, and the fates of Korg, Miek, Jane Foster, Ned Leeds, Pepper Potts, Valkyrie, and Shuri are massive spoilers.
* {{Understatement}}: PlayedForDrama. Captain America is left so utterly (and understandably) stunned by Thanos using the Infinity Stones to literally kill half the universe, that his only response is a quiet, affectless "Oh, God."
* UnspokenPlanGuarantee: Hinted at; the exact details of the plan to attack Thanos on Titan and take the Gauntlet from him are not disclosed to the audience, but although that plan ultimately fails, after Strange stated that he would be willing to let Tony and Peter die to protect the Time Stone and handed it over to Thanos anyway, coupled with his last words of "There was no other way", it suggests that Strange actually ''planned'' for the battle to turn out that way....
* UpgradeArtifact: Whereas Mjölnir was actually a PowerLimiter for Thor's lightning powers, Stormbreaker is this and ''enhances'' his powers.
* UpToEleven: Everything that has accumulated throughout the MCU up to this film is brought to bear against Thanos in the ultimate battle to protect the universe from his tyranny. All creative and filmic aspects are this as well. The story is the biggest one yet, the most serious of any Marvel movie to date, and the cast (of ''62 characters'') is the biggest of any superhero film ever.
%%
%% Unexpected Character is now a YMMV item, put all examples on the YMMV page.

* UseYourHead: Thanos rams his head against Iron Man's helmet during their fight on Titan.
* UtopiaJustifiesTheMeans: Thanos intends to kill half the universe to solve the problem of limited resources and overpopulation. This, he says, will ensure that everyone is prosperous, "a full belly and clear skies" as he puts it. He succeeds horribly.
[[/folder]]
[[folder:V]]
* VillainProtagonist: Similar to his depiction in ''The Infinity Gauntlet'', Thanos is unquestionably the central character of ''Infinity War''. The film explores his backstory and motivations, giving him sympathetic qualities and a meaty dramatic arc. Every other character arc or beat (such as Tony Stark facing his fears, Gamora dealing with her familiar feelings, and Thor grieving for his friends and family) exists in the orbit of Thanos. This is particularly felt when after the post-credits scene, it is announced that ''Thanos'' will return rather than the Avengers.
-->'''Kevin Feige:''' Thanos in ''Infinity War'' is, you know, in a movie that has [[LoadsAndLoadsOfCharacters a lot of characters]], you could almost go so far as to say he is the main character, and that's a bit of a departure from what we've done before, but that was appropriate for a movie called ''Infinity War''.
* VillainRespect:
** Thanos says "I like him" of Quill when Quill proves willing (after much hesitation) to kill Gamora if it means keeping the Soul Stone out of Thanos's hands. He doesn't actually let Quill kill Gamora, of course, but appreciates his resolve.
** Openly declared to Tony Stark by Thanos for his futile but courageous final stand against him; the tyrant even sincerely wishes that the people of Earth will remember him for his heroism.
** Silently done, when Thanos begins his march in Wakanda to the final Stone defeating every hero with one hand; Captain America not only blocks his path twice, but is capable of holding the Mad Titan powered by ''five'' Infinity Stones back, which should be impossible. This earns him a smile of approval from Thanos as he uses both hands to beat Cap back.
** In a broad sense, Thanos shows proper respect to many of the heroes, including the above-mentioned three. He uses only brute force on The Hulk instead of the Power Stone to give Hulk a chance. He trades words of philosophy with Doctor Strange with no hostility, truly trying to make the wizard understand his motives. He is actually impressed Wanda had the will to kill Vision (her lover) to keep the Mind Stone from him. Finally, he's also impressed that Thor can severely wound him when he gains all the Infinity Stones. All in all, he truly means it when he says he's trying to be unbiased and fair in his crusade.
* ViolentlyProtectiveGirlfriend: Wanda for Vision when they're attacked by Proxima and Corvus. She repeatedly blasts them away from Vision when they try to take the Mind Stone from him, refuses to leave when he asks her (for her own safety) to do so, and prepares to take them both on by herself until [[BigDamnHeroes Cap and his team show up]]. Which just makes it all the more tragic when she's forced to kill him by destroying the Mind Stone despite all her efforts to protect him. And when she sees Thanos about to kill Vision again, she furiously lunges at him, only to be blown back.

[[folder:W]]
* WalkInChimeIn: T'Challa promises Steve and his group that they will fight alongside the full strength of Wakanda's military, and Bucky appears, commenting, "...and a semi-stable hundred-year-old man".
* WasItReallyWorthIt: When Thanos assembles the Infinity Stones and succeeds in killing half the universe, he's visited by a vision of Gamora as a child, asking what he had to sacrifice to achieve his goal. Thanos's answer?
-->'''Thanos:''' ''... Everything.''
* WeHaveReserves: Black Panther says that the invaders will get nothing in Wakanda with "dust and blood". Proxima Midnight replies that "we have blood to spare" as she reveals heaps of alien troops. Who then hurl themselves at the shield, getting burned and dismembered until some of them finally make it through intact.
* WellIntentionedExtremist: Thanos wants to cull the universe of half of its population because he thinks that overpopulation will eventually lead to even ''more'' people dying and a completely unnecessary amount of suffering to boot. Why? Because that's exactly what happened to Thanos's homeplanet of Titan when he stepped away from doing what was "right" the first time.
* WeNeedADistraction: When Peter Parker's SpiderSense activates on the school bus and he sees a Q-ship in the distance, he taps Ned's face and asks him to create a distraction. Ned immediately enthusiastically shouts "We're all gonna die!", herding the rest of the kids to the back of the bus. Whether or not Ned actually heard Peter or saw the ship and panicked on his own doesn't matter, since Peter got his chance to leave the bus unnoticed.
* WhamEpisode: Without question, the biggest one in the MCU. Most of our heroes are dead and there's no clear way to undo the massive amount of damage that Thanos has done to the Universe.
* WhamLine: Several.
** The Earth-based heroes' first encounter with the Children of Thanos. When Bruce tries HulkingOut like Tony suggested...
--->'''Hulk:''' ''[[BigNo NOOOO!!!]]''
** Gamora is held captive by Thanos, and he says he sent her on a mission to find the only Infinity Stone unaccounted-for. And he knows she ''didn't'' fail.
** Perhaps the biggest is when the Red Skull tells Thanos and Gamora that to get the Soul Stone, Thanos must "sacrifice that which he loves the most." Gamora laughs that Thanos loves nothing as he turns to look at her.
--->'''Gamora:''' Tears? Really?\\
'''Red Skull:''' They are not [[EvenEvilHasLovedOnes for him]].
** When Thor runs Thanos through the chest with Stormbreaker.
--->'''Thanos:''' You should have gone for the head. ''[snap]''
** A particularly heartbreaking one as Thanos succeeds in wiping out half of the universe's population, and the audience is wondering which of their heroes they're gonna watch die next:
--->'''Peter Parker:''' Mr. Stark? I don't feel so good.
* WhamShot:
** The guardian of the Soul Stone is none other than a still-alive ComicBook/RedSkull.
** T'Challa holds the relatively expendable Okoye's hand as the audience expects her to die, only to see T'Challa, a character presumed immortal due to his popularity, crumble to ash.
** As usual, TheStinger provides one where Nick Fury tries to send a distress signal before he gets disintegrated. The symbol that appears on his communicator resembles that of [[Film/CaptainMarvel2019 Carol Danvers']] costume.
* WhatHappenedToTheMouse:
** Wong mentions that he's going back to protect the Sanctum after Strange is kidnapped as Tony and Peter go after him. His fate is not known as of the end of the film and the fingersnap.
** Hawkeye and Ant-Man never appear in the movie. It's mentioned that they've gone back to their families; their fates (and that of their families') after Thanos wiped out half of the universe's population are not revealed, either.
** Valkyrie, Korg and Miek are nowhere to be seen as Thanos storms the Asgardian ship and lays waste to apparently everyone on board. Director Joe Russo confirmed that Valkyrie at least survived after the film's release. In the film itself, it is mentioned repeatedly that Thanos kills half of the people and lets the remaining half live; thus, it can be inferred that half of the Asgardian/Sakaarian refugees aboard survived.
* WhatMeasureIsAMook: On the one hand, the heroes display clear horror at the casual disregard the Children of Thanos have for their "soldiers'" lives. On the other hand, while Cap tells Vision they "don't trade lives" he seems to have no problem risking the lives of hundreds of Wakandan soldiers to buy time for Vision.
* WhatMeasureIsANonHuman: For heroes that usually go for ThouShaltNotKill, facing HumanAliens erase any qualms about that, such as Spider-Man creating the plan that sends Ebony Maw into space.
* WhatTheHellHero:
** Tony Stark tells Bruce Banner that (due to the events of ''Film/CaptainAmericaCivilWar'') he won't contact Steve Rogers despite Thanos's imminent arrival because the two are not on speaking terms, prompting Banner to question this reasoning and later call Rogers himself.
** Eitri is really unhappy to see Thor, saying "You were supposed to protect us. Asgard was supposed to protect us!" Thor explains that Asgard was destroyed.
** Tony is distraught at Strange giving up the Time Stone and asks "Why did you do that!?" Like Thor, Strange is able to a give good answer why, which shuts Tony up.
* WhoAreYou: Thor asks, "Who the hell are you guys?" after he wakes up on the Guardians' ship.
* WhoNamesTheirKidDude: Upon hearing Stephen Strange introduce himself as "Doctor Strange", Peter Parker responds "Oh, we're using our made-up names. Then, I am Spider-Man." Strange doesn't even bother clearing it up.
* WillReturnCaption: The film ends with a "Thanos will return" caption, which then crumbles to dust.
* WizardDuel:
** Doctor Strange and Ebony Maw engage in one in New York, and Strange loses. Although since a spell prevents Maw from just seizing the necklace, he takes Strange prisoner and brings him on his ship.
** Doctor Strange vs. Thanos wielding four Infinity Stones. They throw energy beams at each other, Strange creates two dozen copies of himself which Thanos dispels, and so on.
* TheWorfBarrage: During his LastStand against Thanos, Iron Man unleashes several old and new weapons in his suit, weapons that had defeated many enemies before and even hurt the {{big bad}}s of the previous Avengers movies. He uses everything in his arsenal, to the point of almost completely exhausting his nano-machine supply, and all he gets for his effort is "a drop of blood."
* TheWorfEffect:
** Thor is beaten offscreen by Thanos before the movie even starts, meaning our villain is introduced dragging the God of Thunder's limp body around like a doll so you know he won't be taking any prisoners.
** Hulk gets beaten handily during the opening sequence just to drive home how unstoppable Thanos is. Ebony Maw even prevents the Children of Thanos from fighting Hulk just so Thanos "can have his fun," and Thanos seemingly takes him on without the aid of the Gauntlet's power and purely his own strength.
** The first scene has Thanos already holding an Infinity Stone -- the Power Stone, which was under the protection of the [[Film/GuardiansOfTheGalaxy Nova Corps on Xandar]], meaning he had already taken it by force. Thor later confirms it, letting us know all of Xandar was decimated in order to demonstrate that yes, Thanos is strong.
* WorldOfSnark: If you thought every MCU movie before featured droll wit, you ain't seen nothing yet because they all come together into one big ball of it in this film, considering it combines Creator/TaikaWaititi's humour from ''Film/ThorRagnarok'', Creator/JamesGunn's humour [[Film/GuardiansOfTheGalaxy from both]] [[Film/GuardiansOfTheGalaxyVol2 films of the Guardians]], and the tendency of the MCU as a whole to give even the darkest, most stoic characters at least a single moment of snark. Then again, given the [[DarkerAndEdgier nature of the film]], the moments ''are'' few and far between.
* WorthyOpponent: Thanos grows to respect Stark, both for their similarity in being "cursed with knowledge" and for his, Stark's, LastStand. Tony himself is shocked when Thanos addresses him by name.
* WoundThatWillNotHeal: Vision gets impaled by Corvus's spear which is capable of injuring him even in intangible form. While he manages to survive, he spends the rest of the movie incapacitated.
* WreckedWeapon: After Thanos snaps his finger with all the Stones installed and wipes out half the life in the universe, the gauntlet looks charred and cracked. It's not clarified if the gauntlet is actually damaged or hindered in its abilities (Thanos easily teleports away afterwards), but the impression is the same.
* WrestlerInAllOfUs: Thanos bodyslams Hulk as a finishing move and later, choke slams Spider-Man.

[[folder:Y-Z]]
* YankTheDogsChain:
** The movie is particularly cruel to Wanda, who spends the majority of the movie trying to find a way to destroy the Mind Stone without killing Vision. After an intense battle on Wakanda, as Thanos approaches the couple, Wanda finally decides to destroy the Mind Stone, killing Vision in a particularly painful manner. While she succeeds, Thanos simply reverses time to restore Vision and his Mind Stone only to rip the Infinity Stone off of Vision.
** Tony, Doctor Strange, and the rest of the Guardians ''finally'' manage to ''almost'' slip the Gauntlet off of Thanos's hand, but [[NiceJobBreakingItHero Star-Lord lets his anger get the best of him and unsurprisingly screws up the entire mission.]]
** The Asgardians had narrowly escaped extinction when their home planet was destroyed in order to kill a mad goddess. Not long into their exodus, their already dwindling population have decreased in half when Thanos attacked their ship. Then, according to WordOfGod that Lady Sif was among those killed by Thanos's culling, half of ''those'' was decreased by half.
** Armed with Stormbreaker, Thor '''almost''' manages to kill Thanos with a blow to the chest... only for Thanos to survive long enough to snap his fingers.
* YouAreNotAlone: Natasha says this near-verbatim about Wanda to Proxima Midnight, when Proxima is seconds from killing Wanda, relishing in her about to die without her lover by her side.
-->'''Proxima Midnight:''' He'll die alone, as will you.\\
'''Black Widow:''' She's not alone.
* YouAreTooLate:
** The Guardians of the Galaxy pick up the distress signal from Asgardians' ''Statesman'' but by the time they arrive, the ''Statesman'' is already destroyed and there's no survivor except Thor.
** Quill, Gamora, Mantis, and Drax head to Knowhere to obtain the Reality Stone before Thanos can. When they arrive, they find he's already there, trying to torture the Stone's location out of the Collector. Gamora attacks and seemingly manages to kill him, only for everything to wash away, revealing that Knowhere has been completely trashed and Thanos already has the Stone.
* YouCantFightFate:
** Thanos is apparently a firm believer in this trope, as he gives the aforementioned "Destiny arrives all the same" speech.
--->'''Thanos:''' Dread it. Run from it. Destiny arrives all the same.
** Thor strongly believes that fate has commanded him to kill Thanos, or else the deaths of Odin, Frigga, Hela, Loki, the Warriors Three, Heimdall, and half the Asgardians would have been for naught.
* YouCantThwartStageOne:
** The film has this feel early on. When Gamora warns that Thanos gaining the Reality Stone in addition to the Space and Power Stones already in his possession will make him too powerful to stop, Thor bluntly replies that he already is.
** It wouldn't be an ''Infinity Gauntlet'' adaptation without it. Thanos gathers all the Infinity Stones and, despite Thor ''running him through'' with Stormbreaker, wipes out half of all sapient life. The surviving heroes are left to pick up the pieces and somehow make things right in the sequel.
* YouHaveNoChanceToSurvive: The Children of Thanos enjoy likening the Avengers' attempts to fight back to parlor tricks and that all is lost for the glory of Thanos.
* YoureInsane: Gamora to Thanos, when he tells her that he genuinely believes that he helped her planet by slaughtering half of its people.
* YoureNotMyFather: Gamora to Thanos, when he repeatedly calls her his daughter.
* YourOtherLeft: When Thanos is about to discover the Guardians on Knowhere, Quill tells Gamora to go to the right, but she goes left instead, prompting Quill to utter exasperatedly, "Your ''other'' right!"
* YouTalkTooMuch: During the opening, Thanos has just slaughtered half of Asgard and beaten Thor bloody, and is holding him by the head, but Thor still isn't impressed by his grandstanding.
-->'''Thanos:''' Destiny arrives all the same. And now it's here... or should I say, I am.\\
'''Thor:''' You talk too much.
* YouWouldntShootMe: Subverted. Gamora convinces Quill to promise to kill her if she's captured by Thanos. When he does capture her, Thanos taunts Quill into shooting her, which he does... only for the Mad Titan to turn the gun and its laser blast into bubbles.
* ZergRush: The Outriders have massive numbers on their side and charge against the Avengers and the Wakandans. Several of them manage to [[DogPileOfDoom take down the Hulkbuster armor, dragging it to the ground]].
