History Film / AvengersAgeOfUltron

* ArtisticLicensePhysics: This is a movie with flying armor suits, Norse gods, and enormous green rage monsters, after all. Yet, [[spoiler:Ultron's plan to scour the Earth with a new extinction-level meteor falls a little short in scale. The Chicxulub meteor which killed off the dinos was about 12 km across, and came in at 20,000 m/s. The rock he's trying to use is, generously, ''one'' kilometer across, and he's dropping it from no more than 18,000 feet (they're still in breathable air when the last evacuees board the lifeboats). It will hit at about 370 m/s. This means it has about 3,000,000 times less energy than Chicxulub. Even his plan to accelerate it down can't make up that much of a gap. It would be a Bad Day in the neighborhood (it's about the energy of the 2011 Japan earthquake), but not even close to an Extinction Level Event.]] On the other hand, [[spoiler:when Wanda briefly reads Ultron's thoughts and sees his agenda, she sees the impactor arriving from outside Earth's atmosphere. So if Ultron hadn't had to drop it prematurely because of the Avengers' interruption, the city could have continued to rise to an indefinite distance]], and it would have had far more time to accelerate. Another problem with Ultron's artifical impact is that much of the damage from an asteroid impact is not from the actual impact per se, but rather that the speed of the asteroid, when arriving from space, is so great that the air in front of it cannot get out of the way in time, becomes tremendously compressed (and thus heats up -- it's why bicycle pumps become so hot), and generates a massive blast of immense heat which is where a great deal of the "explosion" comes from. Even with the engines accelerating it, the city is moving ''much'' too slowly (probably several orders of magnitude too slowly) to accomplish this.

-->'''Wanda:''' I know you're angry. --\\

** At one point, Pietro remarks that he is older than Wanda by 12 minutes. In the comics, she is the older of the two. [[note]]This is also the case with the actors, as Creator/ElizabethOlsen is two years older than Creator/AaronTaylorJohnson[[/note]]

* NearVillainVictory: Ultron [[spoiler:succeeds in levitating Sokovia to planet-killing height then manages to trigger its return trip, and is only stopped thanks to Tony and Thor destroying it at the last possible second.]]

* AllOfThem: After [[ArmsDealer Ulysses Klaue]] gets his [[AnArmAndALeg arm severed to a bit above the elbow]] and is subsequently stuck in the middle of a fight between the opposing teams of ComicBook/TheAvengers versus ComicBook/{{Ultron}}, ComicBook/ScarletWitch, and ComicBook/{{Quicksilver}}.

-++>'''Clint:''' What? [[IronicEcho You didn't see that coming?]]

** In the beginning one of Tony's droids is met with hatred by the locals of Sokovia, and the camera pans to some anti-Iron Man graffiti. In a deleted scene, there is another of Captain America's with the word "fascist" sprayed over it too.

* IronicNurseryTune: The first trailer has a creepy version of "I've Got No Strings" from ''WesternAnimation/{{Pinocchio}}'' playing after Ultron first appears. Ultron also quotes or sings a bit of it a few times in the movie, most creepily when he's [[spoiler:strafing the Avengers in a hijacked Quinjet's minigun]]. Doubles as a ShoutOut to the movie's distributor, Creator/{{Disney}}.

** At one point, Pietro remarks that he is older than Wanda by 12 minutes. In the comics, she is the older of the two [[note]]This is also the case with the actors, as Creator/ElizabethOlsen is two years older than Creator/AaronTaylorJohnson[[/note]].

** [[spoiler:Pietro gets shot at in slow motion three times, with the bullet getting closer each time. The first time Hawkeye shoots once at him through the floor, then he's grazed by a random cop, and he finally winds up shot multiple times by Ultron.]]

* AntiClimaxCut: Hawkeye promises that he's taking the Avengers to a safe house. Cut to their destination, which is... a house. Not anything with security technology or weaponry or protection, just...a regular old house.

* BookEnds:

-->'''Clint:''' What? [[IronicEcho You didn't see that coming?]]

* BulletproofHumanShield: [[spoiler:Pietro]] uses himself as one. An even more absurd example than normal, what given the bullets are being fired from a ''quinjet''.

* CastingGag: Black Widow reveals that her spy training in Russia included forced sterilization to ensure that a female spy's mission isn't compromised by an unplanned pregnancy. Creator/ScarlettJohansson was pregnant during filming. And since she was quite far along while shooting that particular scene, she had to wear a heavy bathrobe and hold a towel in front of her stomach to hide her baby bump...all while talking about how she can't have children.

* AntiClimaxCut: Hawkeye promises that he's taking the Avengers to a safe house. Cut to their destination, which is... a house. Not anything with security technology or weaponry or protection, just, you know... regular old house.

* AppliedPhlebotinum: Loki's scepter, an AncientArtifact with magical SuperEmpowering properties. It is directly tied to all the new lead characters: it grants Pietro and Wanda superhuman abilities, is used to bring Ultron to life, and plays a role in the Vision's creation. It's eventually revealed to [[spoiler:contain the fourth Infinity Stone (the Mind Stone)]].

--->'''Hawkeye:''' The city is flying... we're fighting an army of robots... and I have a bow and arrows... none of this makes any sense.

--->'''Laura:''' I see you with the Avengers, and well... they're like gods.\\

'''Laura:''' Actually, I think they do -- and that's scarier.

--->'''Banner:''' I could choke the life from you without changing a shade.

-->'''Wanda:''' I know you're angry --\\

** Creator/HayleyAtwell, Creator/IdrisElba and Julie Delpy all appear in Cap, Thor and Natasha's "dreams" created by Scarlet Witch.

** Loki's scepter from the previous film. The artificial intelligence found within its gem is used by Tony and Bruce to complete Stark's global defense program Ultron. Later Ultron uses the scepter to [[spoiler:force Helen Cho via mind control into constructing Vision's body and places the scepter's gem on his head. The gem is the MindStone, one of the six Infinity Stones.]].

** Thor mentions that four Infinity Stones have emerged in the past few years. He's encountered the Space, Mind, and Reality Stones across his movies and the first ''Avengers'', but the Power Stone is exclusive to the events of ''Film/GuardiansOfTheGalaxy'' (the Time Stone won't come into play until ''Film/DoctorStrange2016'', and the Soul Stone not until ''Infinity War''), indicating Thor has some awareness of those events, thereby tying them into the overall ''Avengers'' storyline.
* CurbStompBattle: The Avengers vs. HYDRA. The battle is so painfully one-sided even Strucker's mission control mook knows they're screwed, not that it stops them from trying. Only the twins are a threat to the Avengers, and even then only because the Avengers are distracted and unaware they exist.

* ActionPrologue: The film opens with the team battling HYDRA and Baron von Strucker, before moving onto the main plot after the opening credits.

** It appears that the MCU will be calling them Enhanced instead of Mutates (a Marvel term for humans that have gained powers somehow, in contrast to Mutants, who are born powered). This term was coined by Jemma Simmons on ''Series/AgentsOfSHIELD'' as a new classification for the S.H.I.E.L.D. Gifted Index after encountering Calvin Zabo.

* GlobalIgnorance:
** Banner butchers the pronunciation of Wakanda as "Wak-anada", which is pronounced exactly as spelled, multiple times.
** The film itself refers to Klaue's ship as off the coast of "Southern Africa", which is as geographically descriptive and wrong as saying "Northern America".

** [[spoiler:Laura Barton. She was a very minor character in ''ComicBook/TheUltimates'' who only appeared in two issues, and is most notable for [[StuffedIntoTheFridge dying to advance]] Hawkeye's storyline. She is not only alive in the movie, but has a fairly sizable role and gets some great lines]].

** During one speech, Ultron notes that Invaders create Avengers. ''ComicBook/TheInvadersMarvel'' were the first (in-universe chronology) team that Captain America was a part of, and he joined the Avengers afterwards.

''Avengers: Age of Ultron'' is the 2015 sequel to ''Film/{{The Avengers|2012}}'' and the eleventh feature film in the Franchise/MarvelCinematicUniverse and the fifth instalment of Phase 2, written and directed by Creator/JossWhedon.

* MenacingHandShot: [[spoiler:As Wanda approaches a wounded Ultron and prepares to finish him off in response to Pietro]]'s death, the camera focuses on the telekinetic energy emitting from her right hand to illustrate [[TranquilFury her simmering rage]].]]

* AnArmAndALeg: Klaue tells Ultron that he reminds him of Tony, and Ultron accidentally cuts his arm off in a fit of rage.

** Captain America runs over HYDRA mooks with the motorcycle he is riding and then flips it over throws it at a HYDRA jeep, wrecking it.

** [[spoiler:Klaue gets one of his hands severed by Ultron. In the comics, his right hand was blown off and replaced with a sonic weapon that later became one of his visual trademark. Ultron chops off his left arm, however.]].

** Played with regarding Clint; [[spoiler:He stuns Wanda with a taser arrow before she mind warps him, while commenting about [[Film/TheAvengers2012 not being a fan of the mind control thing]].]]

** [[spoiler:Wanda ends the movie as the only surviving member of her family, due to PIetro dying.]]

--->'''Steve:''' ...You ''had'' to ask.
--->'''Ultron:''' ''This'' is the best I can do.

''Avengers: Age of Ultron'' is the 2015 sequel to ''Film/{{The Avengers|2012}}'' and the eleventh feature film in the Franchise/MarvelCinematicUniverse and the penultimate instalment of Phase 2, written and directed by Creator/JossWhedon.

* ApatheticCitizens:
** The citizens of Novi Grad do not take well to the Iron Legion telling them to shelter in place. Most of them instead pelt the drones with produce and damage one of their heads.
** When the twins are evacuating Novi Grad prior to the final battle, Pietro goes to the police station to shout a warning. No one seems to pay attention to him, forcing him to dash off, come back with a gun, and fire a volley into the ceiling.

'''Ultron:''' ''[closes his eyes briefly]'' Now, so are you. ''[Klaue's underling's phone vibrates as the money is deposited]'' It’s all under your dummy holdings? Finance is so weird. But I always say, “Keep your friends rich and your enemies rich, and wait to find out which is which.”

'''Ultron:''' ''[closes his eyes briefly]'' Now, so are you. ''[Klaue's underling's phone vibrates as the money is deposited]''

-->'''Clint:''' What? You didn't see that coming?

-->'''Wanda Maximoff:''' [[DirtyMindReading I looked in your head, and saw annihilation]].
-->'''Vision:''' [[DoubleEntendre Look again]].
-->'''Clint Barton:''' ''[scoffs]'' Yeah. Her [[FemaleGaze seal of approval]] means jack to me.

** The first thing Wanda says to Vision, the synthezoid who will eventually become her lover, is, "[[DirtyMindReading I looked in your head]], and saw annihilation."
-->'''Vision:''' Look again.
-->'''Clint:''' ''[scoffs]'' Yeah. Her seal of approval means jack to me.

* FanDisservice: Maria Hill is seen picking glass out of her bare feet after the first battle with Ultron. At least it's seen from a distance.

--->'''Ultron:''' [[AsTheGoodBookSays And on this rock]], [[Literature/TheFourGospels I will build my church.]]

-->'''Steve:''' [[YouJustHadToSayIt You had to ask.]]
-->'''Ultron:''' ''This'' is the best I can do.

--->'''Wanda Maximoff:''' Ultron can't tell the difference between saving the world and destroying it. Where do you think he gets it from?

'''Wanda Maximoff:''' I just did. Do you know how it felt? ''[rips Ultron's core out and crumples it like tissue paper]'' [[TranquilFury It felt like that]].

* UnusuallyUninterestingSight: Pietro zooms into a police station, frantically warns the cops to start evacuating the town and zooms off. Their reaction? Go back to what they were doing. He has to come back and ''fire a rifle into the ceiling'' before they'll move.

* WhyDontYaJustShootHim: Surprisingly averted. Ultron earns the distinction of being the first major villain in the MCU who tries to use the most [[MundaneSolution simple, effective and straightforward solution]] first ([[spoiler:stealing the nuclear codes and using the nukes to destroy humanity]]) and only resorts to the more "colorful" method because that plan keeps getting thwarted [[spoiler:by J.A.R.V.I.S. and later Vision]]

* AIIsACrapshoot: Despite being created by Tony Stark to help the heroic Avengers, Ultron decides he can only make the world safer by violently forcing it to evolve, before someone like [[GreaterScopeVillain Thanos]] just destroys the planet outright. It's pointed out by Wanda and [[spoiler:Vision]] later in the film that Ultron basically wants to save humanity ''and'' wipe it out, and has concluded that the former can be accomplished by the latter.

* AppliedPhlebotinum: Loki's scepter, an AncientArtifact with magical SuperEmpowering properties. It is directly tied to all the new lead characters: it grants Pietro and Wanda superhuman abilities, is used to bring Ultron to life, and plays a role in [[spoiler:the Vision's creation]]. It's eventually revealed to [[spoiler:contain the fourth Infinity Stone (the Mind Stone)]].

** J.A.R.V.I.S. in a sense; he ascends from an A.I. created for the MCU to becoming tied to the origin of [[spoiler:the Vision]].

** A rematch of sorts happens when [[spoiler:Vision]] first clashes with Ultron and [[spoiler:Vision cuts off Ultron's access to the Internet, trapping him in his physical form]].

** It happens literally in the confrontation over [[spoiler:Vision's creation]], where he sees a bullet emerge from the floor, quizzically regarding it until the glass it penetrated shatters and he falls down to the lab below, where Hawkeye is waiting.

* InYourNatureToDestroyYourselves: The artificial intelligences Ultron and [[spoiler:Vision]] both agree that humans are "odd creatures" who are ultimately doomed, but reach opposite conclusions on what lesson to draw from this. [[StrawNihilist Ultron]] thinks it means he should aid humanity's destruction, while [[spoiler:[[TheAntiNihilist Vision]]]] thinks he should protect them.

* JustAMachine: PlayedForLaughs in [[https://www.youtube.com/watch?v=7XrDgwFxRLo this scene]], when Steve and Tony try to justify why [[spoiler:Vision]] can wield Mjölnir when they can't even pick it up.

* {{Magitek}}: Ultron and [[spoiler:Vision]], robot-like technological beings that gain sentience through magical interference.

* MetaOrigin: The film ties the origins of Ultron, Vision, Scarlet Witch, and Quicksilver together via [[spoiler:the Mind Stone]].

* RoboFamily: Tony Stark has built a number of A.I.s that join the "family business" so to speak. DUMM-E, J.A.R.V.I.S. FRIDAY, and partially (as in, partial credit for creation), [[spoiler:Vision]] either help him in Stark Industries and/or in Avenging. In fact, this movie plays out like a teenager rebelling against his father and Tony even jokes that Ultron is "breaking your old man's heart".

* ShipTease: In a reference to [[Film/CaptainAmericaCivilWar their]] [[Film/AvengersInfinityWar impending]] [[Series/WandaVision relationship]], [[spoiler:Wanda spends most of Vision's first scene checking out his body, and later spies on him talking with Thor while she and Pietro are gearing up. In the FinalBattle, Vision also goes back into the falling Novi Grad to rescue her before Tony and Thor blow it up, and she looks at him with what seems to be admiration.]]

* SkewedPriorities: A comedic example. At the film's end, Thor is trying to have a serious discussion with Steve and Tony about [[spoiler:the Infinity Stones]] but the two of them are stuck on a debate about how [[spoiler:Vision might not truly count as worthy to use Mjölnir.]] They are just having fun and the conversation turns serious a moment later.

* StrawNihilist: During Ultron's discussion with [[spoiler:Vision]] at the end, they both agree that [[InYourNatureToDestroyYourselves humanity is doomed to destroy itself]]. However, whereas Ultron concludes that humans deserve to go extinct, [[spoiler:Vision]] believes it is better to [[TheAntiNihilist cherish something no matter how fleeting it may be]].

* TrustPassword: The Avengers are initially distrustful of [[spoiler:Vision]], seeing as he's created by Ultron. They all trust him a little bit more, though, when [[spoiler:Vision casually hands Thor Mjölnir, a weapon that can't even be ''picked up'', much less handled, by anyone but the worthy.]]

* OlderThanTheyThink: This is not the first universe where Tony Stark created Ultron instead of Hank Pym. It has happened at least once before, over have a decade earlier in the NextAvengersHeroesOfTomorrow movie.

** So far, this is the only film that features Thor but not Loki (deleted scene notwithstanding). In every other movie in which Thor appears, Loki shows up too. This includes ''Film/{{Thor}}'', ''Film/ThorTheDarkWorld'' and ''Film/ThorRagnarok'', as well as ''Film/{{The Avengers|2012}}'' and ''Film/AvengersInfinityWar''. Both Thor and Loki appear in ''Film/AvengersEndgame'' to one extent or another as well. This would also mean it's the only ''Avengers'' movie that does not feature Loki in some capacity.

* BittersweetEnding: [[spoiler:The Avengers manage to protect the people of Sokovia, defeat Ultron, and SaveTheWorld. In the process, Quicksilver dies in the FinalBattle, Hulk goes into hiding without telling the others anything, Thor returns to Asgard to deal with the Infinity Stone issue, and Hawkeye and Iron Man leave the team for the time being, prompting Captain America and Black Widow to create a new team with Scarlet Witch, Vision, War Machine, and the Falcon, and the Sokovian capital is mostly destroyed. OhCrap And Thanos is going to take Infinity Stones... himself.]]]]

** The "Veronica" system (i.e. Hulkbuster Iron Man) can be deployed from a satellite to anywhere in the world when summoned. It contains multiple backup parts for the modular Hulkbuster armor -- at the very least enough to furnish an entire second copy of the suit -- to replace anything the Hulk damages when trying to subdue him. It's powered by over a dozen arc reactors and its repulsor output in each hand is equivalent to the normal armor's unibeam. It's bigger than the Hulk and at least as strong. It has has a [[RapidFireFisticuffs pneumatic piston fist]], which can also transform into a ring clamp in the event that a PunchCatch occurs. Finally, it has a loudspeaker for warning civilians out of the area. In this case, Bruce himself helped design it, so it makes sense it would be prepared to stop his own alter-ego. As a (probably) temporary containment measure until the Veronica system is on site, the satellite can deploy a reinforced box cage around him from above as well (which unfortunately does not contain from beneath). The whole system's [[CripplingOverspecialization sole purpose]] is a contingency if Hulk did not respond to Natasha's CooldownHug (or she was indisposed during a Hulk rampage).

'''Ultron:''' [[SarcasmMode I'm glad you asked that]], because I wanted to take this time [[EvilGloating to explain my evil plan]]!

-->'''Wanda Maximoff:''' [[DirtyMindReading I looked into your head, and saw annihilation]].

* DoesThisRemindYouOfAnything: "Peace in our time." Said once by Tony Stark, three times by Ultron - once by ''replaying a recording'' of Tony. When Steve dresses down Tony for trying to "win a war before it starts", he's not just talking about [[Film/CaptainAmericaTheWinterSoldier Project Insight]] - he's talking about the horrors he fought ''[[UsefulNotes/WorldWarII before]]'' he [[Film/CaptainAmericaTheFirstAvenger went into the ice]]. He's remembering all the fates that were sealed by [[https://en.wikipedia.org/wiki/Peace_for_our_time Neville Chamberlain]] making a decision for everyone else; "Peace ''[[BeamMeUpScotty for]]'' our time," a year before Hitler invaded Poland.

** When Wanda, delirious as she recovers from Clint's taserarrow, notices Bruce alone on the Quinjet, she tells Pietro, "I want... the big one." It's especially hilarious given the Hulk's symbolism as Bruce's unfettered, instinct-driven alter ego.

** When his fortress is under attack, Strucker oversees the strategy against the Avengers. One of his lackeys mentions the twins. Strucker refuses to use them for combat yet, they are a valuable resource and must stay concealed. He insists, "the twins...", and points Strucker to watch in their direction. They are no longer there, they left to fight the Avengers on their own initiative.

* MeleeATrois: [[spoiler:When the Avengers arrive at Klaue's shipwreck hideout and start fighting Ultron and the twins over the Vibranium, a wounded Klaue orders his own men to attack both. This forces Thor, Steve, Clint and Natasha to have to engage them, thet twins and the Ultron sentries while Tony dukes it out with Ultron's main body.]]

* MomentOfSilence: The music cuts out when [[spoiler:Pietro]] dies, with sad music fading in while Wanda's knees give out and she inaudibly screams.

** The FreezeFrameBonus on Klaue's dossier: he was hired to kill T'Chaka at the Bilderberg conference in the case that he refused to trade Wakanda's resources, and his great-grandfather was killed by a past Black Panther during a failed invasion of Wakanda. Both of these events were shown in {{Flashback}}s in the ''WesternAnimation/BlackPanther'' animated series ([[spoiler:though T'Chaka ''survived'' this attempt in the MCU]]), which were adapted from and by Creator/ReginaldHudlin's "Who is the Black Panther?" storyline).

** When Tony is looking through his old A.I. chips, one of them is seen marked "[[http://www.comicvine.com/jocasta/4005-3318/ JOCASTA]]."

** It's also an allusion to one of the most popular Avengers stories, ''Ultron Unlimited''. In it, Ultron invades a fictional East-European country using an army of his drones. Sound familiar?

* NotEvilJustMisunderstood: The Maximoff twins are codified as secondary antagonists, until it's dug deeper that they lost their parents 15 years ago to one of Stark Industries' bombs when they were kids and want revenge. When Wanda looks into Ultron's mind and sees what he really desires, she and her brother join the Avengers side.

* NotHisSled: The usual outcome in comic book fights against Ultron is that he is destroyed, but a copy of the AI lives on and eventually reconstructs itself. Here, [[spoiler:Wanda destroys Ultron's main body, and Vision destroys the back up body he tries to use to make a getaway.]]

* RoaringRampageOfRevenge: [[spoiler:When Ultron kills Pietro, Wanda breaks down in anguish and emits a wave of magical energy, ''obliterating'' the Ultron sentries near her. She then abandonsher post and rips the heart out of Ultron Prime's body.]]

** Clint and Pietro trying to one-up each other (along with some banter) every time they meet.

* SecretTestOfCharacter: Not so much secret as unintentional; [[spoiler:When the Avengers are grilling the newly-born Vision about his allegiance and wondering whether any of Ultron's personality got into him, he affirms that he is on the side of life while casually lifting Mjölnir and handing it to Thor. Given that only those truly worthy of wielding its power (read: the pure of heart) can lift it, this settles the debate in Thor's mind as he takes the hammer, pats Tony on the shoulder, and goes off to get ready for the FinalBattle. Later gets [[DiscussedTrope discussed]] due to the fact that, as a machine, Vision may be operating under a loophole that things like [[Film/ThorTheDarkWorld a coat rack]] or an elevator do that would allow him to lift the hammer without being worthy of it.]]

** Wanda and Pietro are the only successful product of HYDRA's human enhancement experiments. Ultron's comments (and the tie-in episode of ''Series/AgentsOfSHIELD'') imply a not-insignificant number of failures.

* SpotlightStealingSquad: There's no debate that Hawkeye steals the show overall -- his focus scenes are so effective and round him out to a large enough degree that it feels almost like this is ''his'' movie, first and foremost. Wanda also manages to run away with a good portion of the ending.

** Ultron could have escaped the final battle in the stolen Quinjet, but he insists on doubling back on a bombing run to strafe the Avengers with its gatling gun. This culminates in Hulk ripping him from the cockpit, and Wanda ripping his core out as retaliation for Pietro's death.

* VillainsActHeroesReact: {{Discussed|Trope}}. Tony brings this up after the Avengers confront him about creating Ultron. Tony accuses the team of being fine with just defeating bad guy after bad guy, and not thinking about the bigger picture, namely, that one day the aliens who attacked Earth will return with an even bigger army. He thus created Ultron as a preemptive move to stop such a disaster, and others, from ever happening. Steve Rogers, who's seen a preemptive scheme go horribly wrong in ''The Winter Soldier'', retorts that trying "to win a war before it starts" only puts innocents in the crossfire, which Ultron does. Nevertheless, Tony still sees Steve as shortsighted when the soldier's response for one day facing the aliens again is merely the team fighting together again.

** Scarlet Witch's eyes glow red when she uses her powers, as do those who are under her MindRape.

* ArtisticLicenseBiology: Klaue mentions that his greatest fear is the [[https://en.wikipedia.org/wiki/Cuttlefish cuttlefish]], describing it as a deep-sea fish that uses "disco lights" to hypnotize its prey before eating it. Either Klaue was misremembering or the documentary he watched was inaccurate. Cuttlefish are not fish, tend to live in the shallows, and use their "flashing lights" either for camouflage or communicating with each other. The description Klaue gives fits the [[https://en.wikipedia.org/wiki/Anglerfish anglerfish]] better than the cuttlefish.
* ArtisticLicensePhysics: This is a movie with flying armor suits, Norse gods, and enormous green rage monsters, after all. Yet, [[spoiler:Ultron's plan to scour the earth with a new extinction-level meteor falls a little short in scale. The Chicxulub meteor which killed off the dinos was about 12 km across, and came in at 20,000 m/s. The rock he's trying to use is, generously, 1 km across, and he's dropping it from no more than 18,000 feet (still in breathable air). It will hit at about 370 m/s. This means it has about 3,000,000 times less energy than Chicxulub. Even his plan to accelerate it down can't make up that much of a gap. It would be a Bad Day in the neighborhood (it's about the energy of the 2011 Japan earthquake), but not even close to an Extinction Level Event.]] On the other hand, [[spoiler:Wanda's vision showed the impactor arriving from a great distance away from Earth. So if Ultron hadn't had to drop it prematurely because of the Avengers' interruption, the city could have continued to rise to an indefinite distance]], and it would have had far more time to accelerate.
** Another problem with Ultron's artifical impact is that much of the damage from an asteroid impact is not the impact per se, but rather that the speed of the asteroid, when arriving from space, is so great that the air in front of it cannot get out of the way in time, becomes tremendously compressed (and thus heats up - it's why bicycle pumps become so hot), and generates a massive blast of immense heat which is where a great deal of the "explosion" comes from. Even with the engines accelerating it, the city is moving ''much'' too slowly (probably several orders of magnitude too slowly) to accomplish this.

** Loki's scepter from the previous film. The artificial intelligence found within its gem is used by Tony and Bruce to complete Stark's global defense program Ultron. Later Ultron uses the scepter to [[spoiler:force Helen Cho via mind control into constructing Vision's body and places the scepter's gem on his head]].

* ChekhovsGunman: A deleted scene shows that [[spoiler:the boy who Pietro dies protecting from Ultron was the boy that Ultron had used to summon the Maximoff twins to meet him.]]

--->'''Clint:''' ''[melodramatically]'' "Whosoever, be he worthy, shall haveth the power." ''[normal]'' Whatever, man! It's a trick! It's a circus sideshow, and that is it. And you know it.

* ColonyDrop: [[spoiler:Ultron can't get the nuclear codes to destroy humanity thanks to JARVIS, so he transforms an entire city into a FloatingContinent powered by a vibranium reactor that he plans to raise up into orbit and drop on the Earth to create an extinction level event.]]

** The "Veronica" system (i.e. Hulkbuster Iron Man) can be deployed from a satellite to anywhere in the world when summoned. It contains multiple backup parts for the modular Hulkbuster armor -- at the very least enough to furnish an entire second copy of the suit -- to replace anything the Hulk damages when trying to subdue him.

As a (probably) temporary containment measure until the Veronica system is on site, the satellite can deploy a reinforced box container around him from above as well (which unfortunately does not contain from beneath). The whole system's [[CripplingOverspecialization sole purpose]] is a contingency if Hulk did not respond to Natasha's CooldownHug (or she was indisposed during a Hulk rampage).
** [[spoiler:Tony has dozens of A.I.s to choose from in the event that something ever happened to J.A.R.V.I.S.]]

-->'''Wanda:''' [[DirtyMindReading I looked into your head, and saw annihilation]].

-->'''Clint:''' ''[scoffs]'' Yeah. Her [[FemaleGaze seal of approval]] means jack to me.

** After Bruce fell [[ThanksForTheMammaries into Natasha's boobs]], she told him to "not turn green". Remember that he transforms when his heart rate is high enough.
** When a gasping Wanda plans to hex Bruce and turn him into the Hulk, she declares "I want... the big one." It's especially hilarious given the Hulk's symbolism as Bruce's unfettered, instinct-driven alter ego.

** During the opening battle, Tony runs into a brief setback and curses; Captain America immediately gives him a rebuke for his language. In exactly two words, we have not only Iron Man and Captain America, but ''the entire movie'': how do you respond to an ugly world?

* EvilOnlyHasToWinOnce: Since Ultron's M.O. is to basically eradicate all human life, this goes without saying. [[spoiler:Taken a bit more literally during the last stand, where if even one of Ultron's sentries manages to deactivate the device holding up the city, it will come crashing down and obliterate the planet. [[NearVillainVictory The last one does succeed,]] but Iron Man and Thor manage to break up the landmass before it collides.]]
* ExactWords: When Helen teases Clint after treating his wounds that his girlfriend wouldn't be able to tell the difference, he replies that he doesn't have a girlfriend. [[spoiler:That's because he has a wife instead.]]

* TheExtremistWasRight: [[spoiler:To counter Ultron and his ability to jump his consciousness into the internet, Tony hatches a mad science plan to create another A.I. to upload in an artificial body. This leads Captain America and the twins to attack him to prevent the upload, but Thor sides with Tony and helps bring it about. In the end it is the Vision that is key to permanently defeating Ultron.]]

** Among Tony Stark's collection of spare A.I. assistants is a disc labelled "JOCASTA".

** The film itself refers to a location as off the coast of "Southern Africa", which is as geographically descriptive and wrong as saying "Northern America".
* GlowingMechanicalEyes: Most of Ultron's robot bodies have glowing eyes, starting with the light blue of the Iron Man suits, but eventually shifting to [[RedEyesTakeWarning blood red]] if he's directly controlling them.

* GoshDangitToHeck: After Cap admonishes Stark for his [[PrecisionFStrike curse]] at the beginning of the film, Stark, and later Fury, [[RunningGag lapse into this a few times]] to annoy Steve.

* GreenRocks: What the Mind Stone amounts to in this movie. Previously, Loki was mostly using it to mind-control and influence people, but here it is used by HYDRA to power their weapons and enhance human beings (although only the Twins survived the process). Later, Tony Stark and Bruce Banner studying it allow them to make an Artificial Intelligence more advanced than anything on Earth. And then, [[spoiler:it is integrated into the creation of the Vision, giving him superpowers like flight and laser beam]].

* TheHeart: Hawkeye's character development makes him into this for the team. As the only Avenger without any super powers or a DarkAndTroubledPast, [[spoiler:as well as a wife and kids to go home to,]] Clint helps keep the team grounded emotionally and provides a safe haven for them, when they need to work through the emotional trauma inflicted on them by [[spoiler:Scarlet Witch.]] He also delivers an amazing LetsGetDangerous speech to [[spoiler:Wanda]], during the final battle with Ultron.

* HeroInsurance: After the huge collateral damage caused in previous missions, the Avengers focus a lot of energy on actually protecting civilians, rather than just fighting the bad guys. It's mentioned that Stark Industries runs an aid foundation to help communities devastated by Avenger-related disasters, Tony's first priority when fighting the Hulk is to get him out of a populated area, and the primary obstacle to stopping the attempted ColonyDrop of Sokovia is how to get the inhabitants to safety. If it were just a case of blowing the FloatingContinent up, they could have done it much earlier and without much difficulty, which is of course ''why'' Ultron uses a heavily-populated city as his "asteroid".

** Falcon pops up briefly in order to tell Cap he's still searching for Bucky.

** At one point, Pietro is running around taking shots at the Avengers. As he sees Mjölnir flying by, he doubles back to make use of it. Cue the hammer dragging him into a pile of crates.
** During the battle in Korea, Hawkeye opens fire on Ultron in the Quinjet. In the climax [[spoiler:Ultron hijacks the Quinjet and attempts to kill Hawkeye. Quicksilver averts this with a HeroicSacrifice.]]
** Ultron's speech to the twins is centered around this -- that people ultimately create that which supplants them. [[spoiler:In the end, Ultron himself is undone by his own "child". Wanda rips out his main body's control unit while Vision destroys his last backup body.]]

* InstantWinCondition: A rare version that works for the villain. In the climax, Ultron and [[MesACrowd his drones]] only have to touch his device once [[spoiler:to send the gigantic landmass plummeting to the ground at extreme velocity akin to a meteor, creating worldwide extinction.]] The Avengers have to prevent any of them from touching the device. [[spoiler:One of them eventually succeeds because Wanda abandons her post to confront the main Ultron body and rip out his core for killing Pietro, but Thor smashes the device with his hammer while Tony overloads the machine that powers it from below, destroying the landmass before it impacts, [[SubvertedTrope subverting this trope.]]]]

* MeleeATrois: [[spoiler:When the Avengers arrive at Klaue's shipwreck hideout and start fighting Ultron and the twins over the Vibranium, a wounded Klaue orders his own men to attack both.]]

* MomentOfSilence: The music cuts out when [[spoiler:Pietro]] dies, with sad music fading in while Scarlet Witch inaudibly screams.

** In the climax, during the aftermath of [[spoiler:Quicksilver's HeroicSacrifice]], the scene cuts to Hulk rescuing Nat then jumping onto [[spoiler:the Quinjet that Ultron Prime is piloting. Ultron then lets out an annoyed "Oh, for God's sake!" offscreen before being unceremoniously thrown off the jet.]]

** Rhodey ditches both the red-white-and-blue paint scheme and "Iron Patriot" moniker for a return to the dark grey War Machine look and codename.
* MultinationalTeam: [[spoiler:The new Avengers line-up in the ending. Steve is Irish-American, James Rhodes and Sam Wilson are African-American, Natasha is Russian, Wanda is Sokovian (fictional Eastern-European country), and the Vision is a British-accented android]].
* MultipleGunshotDeath: [[spoiler:Quicksilver's corpse]] is riddled with bullets from a Quinjet.

** [[spoiler:At his safe house]], Hawkeye uses his superhuman marksmanship to hit a dartboard's bull's-eye with multiple darts simultaneously.

** Scarlet Witch and Quicksilver don't wear costumes ([[spoiler:Until Wanda gets one at the end]]), but the street clothes they wear in the third act have color schemes referencing their suits from the comics.

** One of Ultron's few Achilles Heels for a long time in the comics was the Scarlet Witch's magic. [[spoiler:While Ultron could be damaged by a lot of sheer fire power, Wanda's power effortlessly yanks out Ultron Prime's core like he was just tin.]]

** As Clint recovers from his injury thanks to Helen Cho's bioengineered synthetic cells, he jokingly says how he'll be immortal and made of plastic. [[spoiler:The Vision]], who is created by Cho in film, is made of plastoid flesh and synthetic blood in the comics.

** A couple of TV spots will have Steve saying "She's with us," which is from a deleted scene where Natasha notices her jacket being worn by Wanda.

* NotSoAboveItAll

** A very brief but beautiful-looking shot in the climax as the camera circles around the Avengers as they battle Ultron's drones while trying to keep them from reaching the core that'll drop Sokovia to the ground.

'''Wanda:''' I just did. Do you know how it felt? ''[rips Ultron's core out and crumples it like tissue paper]'' [[TranquilFury It felt like that]].

** Wanda/Scarlet Witch wears a black outfit with [[ColorCharacter red jacket]]. Subverted after she pulls a HeelFaceTurn.

* RightForTheWrongReasons: Tony thinks that he can upload JARVIS into the computer at the core of the body Ultron built, that JARVIS can control it, and that JARVIS can serve as their ultimate weapon against Ultron. In fact, [[spoiler:the gem/computer that Tony plans to upload JARVIS into is the Mind Stone, it is alive, JARVIS only serves as a template for the Mind Stone to act of its own accord, and it turns out to utterly benevolent. So much so that it can lift Mjöllnir.]]
* RoaringRampageOfRevenge: [[spoiler:When Ultron kills Pietro, Wanda breaks down in anguish and emits a wave of magical energy, ''obliterating'' the Ultron sentries near her. She later rips the heart out of Ultimate Ultron's body.]]
* RoboFamily: Tony Stark has built a number of A.I.s that join the "family business" so to speak. DUMM-E, J.A.R.V.I.S. FRIDAY, and partially (as in, partial credit for creation), [[spoiler:the Vision]] either help him in Stark Industries and/or in Avenging. In fact, this movie plays out like a teenager rebelling against his father and Tony even jokes that Ultron is "breaking your old man's heart".

* ShipTease: In a reference to [[Film/CaptainAmericaCivilWar their]] [[Film/AvengersInfinityWar impending]] [[Series/WandaVision relationship]], [[spoiler:Wanda spies on Vision talking with Thor after he's created. In the FinalBattle, Vision also saves her from being killed when the floating city falls, and she looks at him with what seems to be admiration.]]

* SmallRoleBigImpact: Though he only appears for about five minutes, Ulysses Klaue ends up leading Ultron to his Vibranium stash -- which becomes hugely important to the second half of the story and to the plot of ''Film/BlackPanther2018''.

** [[spoiler:After all of Ultron's bodies are seemingly destroyed, one last one -- the one that Captain America had damaged and thrown off the side -- manages to climb out of the crater, intent on crawling away. Subverted, then, when Vision intercepts and destroys it after a brief heart-to-heart with Ultron.]]
* SomeKindOfForcefield: Strucker's base has a shield around it that glows blue when hit. It is even called "some kind of energy shield" by J.A.R.V.I.S.

* SummonBiggerFish: [[spoiler:When the Hulk goes on a rampage thanks to Scarlet Witch driving him mad, Iron Man calls in the Mark 44 "Veronica", an Iron Man suit even bigger than the Hulk himself. It's also powerful enough for Tony to go toe-to-toe with Hulk long enough to snap Hulk out of his Scarlet Witch-induced psychotic rage.]]

** Tony summosn part of his armor to his right hand when he prepares to grab the scepter.

* SurvivorGuilt: Scarlet Witch's visions show this to be what haunts Steve, but also Tony as well. [[spoiler:Steve suffers because he can never go home after getting frozen, while Tony's vision has him as the last surviving Avenger, [[ForcedToWatch helpless to stop Earth's invasion]].]]
* TakeThat: The Avengers' focus on saving civilians during the climactic battle has been interpreted as a deliberate contrast to Superman's perceived lack of concern for mass casualties in ''Film/ManOfSteel''. While they had been using much the same tactics in the first movie, a brief shot where Iron Man scans a building to ensure that it's empty before throwing Hulk into it stands out, as it had been suggested by a number of fans that such a scene would have helped ''Man of Steel'''s climactic battle.

* TalkToTheFist: In the Avengers' confrontation with Ultron [[spoiler:in his main body after they destroy most of the Ultron Sentries]], during a pause in their attacks, Ultron manages to get out "You know, with the benefit of hindsight..." before Hulk punches him off into the distance.

* TeeteringOnTheEdge: The launching of Sokovia leaves several cars precariously dangling over the edge of broken roads. Steve specifically tries to stop one red convertible, visibly straining to pull it to safety, only to lose his grip when the bumper snaps off sending the car and driver plunging thousands of feet towards the ground. Luckily, Thor is able to catch the car and fly it and its occupant back to solid ground.

-->'''Tony:''' ...[[OhCrap I'm]] [[ThisIsGonnaSuck sorry.]]

** [[spoiler:Pietro promising to pick Wanda up after she has destroyed all the Ultron sentries trying to reverse the anti-gravity device.]]

** Thor boasts that Wanda's MindRape won't work on him as he is not as weak-minded as his mortal comrades. Cue the Asgardian nightmare scene. For bonus points, he walks ''right by her'' while saying this and the audience is led to think that he successfully [[NoSell no-selled]] it at first.

* ThereAreNoCoincidences: Thor mentions that this incident with the Mind Stone means that four Infinity Stones have come into play over the course of the past three years (the others being in ''Avengers'', ''The Dark World'' and ''Guardians of the Galaxy''), which is far too many to be mere chance. At the end of the film, he returns to Asgard to investigate.

* ThouShaltNotKill: Averted: consistent with other Marvel Cinematic Universe films, the Avengers are not averse to using deadly force against human/non-powered targets, as demonstrated in their opening battle with HYDRA. Banner invokes the trope after the battle when he expresses concern over whether the Hulk killed anyone during the fight ([[spoiler:he did, but his teammates choose not to tell him so]]).
* ThreePointLanding: Done by Tony in the beginning because he has to make a stylish entrance.

* TronLines: Natasha's new outfit has blue accents.

* TrustPassword: The Avengers are initially distrustful of [[spoiler:Vision]], seeing as he's created by Ultron. They all trust him a little bit more, though, when [[spoiler:the Vision casually hands Thor Mjölnir, a weapon that can't even be ''picked up'', much less handled, by anyone but the worthy.]]
* TuckAndCover: [[spoiler:Clint does this to a little boy to selflessly protect him with his own body when Ultron starts to fire at Sokovia, but Quicksilver ends up taking the bullets for Hawkeye.]]

* UnderTheTruck: In Seoul, Natasha slides with her bike under the truck where Captain America and Ultron are fighting, before tossing Cap his shield that she picked up earlier.

** Ultron could have escaped the final battle in the stolen Quinjet, but he insists on doubling back to strafe the Avengers with its gatling gun.

* WeComeInPeaceShootToKill: Not an alien in the literal sense, but Ultron nevertheless claims he wants peace. When Thor tells him to stand down if he means it, Ultron retorts that he's confusing "peace" with "quiet".

* YouCantGoHomeAgain: This is Steve's deep-seated fear that Scarlet Witch plays upon to disable him. He looks for any excuse to keep fighting because he has no home to go to if he faces the fact that the war is over. Ultron calls him on it a few minutes before that. Sam had also earlier asked if he'd been looking at apartments in his hometown of Brooklyn again since the events of ''Film/CaptainAmericaTheWinterSoldier''. Steve makes a joke about the neighborhood gentrifying out of his price range, but it's obvious he can't face the idea about settling down anymore than when he was first unfrozen. [[spoiler:At the end of the film, he decides to stick with the new Avengers, admitting that he's no longer the man who wanted to settle down eventually.]]
* YouCantMakeAnOmelette:

* YouCantThwartStageOne: Toyed with. Stage One [[spoiler:(Ultron hacking nuclear launch codes to start WorldWarThree)]] is being continually thwarted throughout the entire film. Stage Two [[spoiler:(Ultron getting Vibranium and Scarlet Witch inflicting Visions on all Avengers)]] succeeds, but Stage Three [[spoiler:(Ultron uploading himself into an organic body)]] is thwarted, leading to Ultron launching Stage Four, which is a variation of Stage One [[spoiler:(causing an extinction level event using the vibranium).]]
* YouHaveGotToBeKiddingMe: Ultron lets out an exasperated "Oh, for God's sake!" when he sees [[spoiler:Hulk scrambling into the Quinjet to kick his ass]].

** Quicksilver and Scarlet Witch seek revenge against Tony Stark because their parents were killed by bombs manufactured by Stark Industries, and they spent two days staring at a defective Stark Industries munition wondering if it would explode before they were rescued. Oddly, while they tell this story to Ultron, Stark is never told why they hate him.

* TheGhost: A few characters such as Jane Foster, Pepper Potts and Loki are mentioned a few times in the film but never appear in the flesh.
