The Director of S.H.I.E.L.D., as a Level 10 Agent, and campaigner for the Avengers Initiative. He comes to each of the heroes one by one, urging them to join S.H.I.E.L.D. in assembling a team to protect the world from its approaching threats. Despite being personally involved in recruiting them, though, he's a busy man and has many urgent responsibilities to juggle, including dealing with his superiors, the World Security Council. Consequently, he can't always be trusted, though he can be counted on to do what he feels is right.
Anti-Hero: He's a practical, levelheaded man who's ultimately fighting for the good side, but he's also a pragmatic manipulator and isn't above deceivingor lying to The Avengers to achieve his goals, such as when the team discovers that he was keeping secrets about using the Tesseract to develop weapons of mass destruction. Even Captain America became appalled with him. He's a good guy, but one doesn't become the world's greatest spy without learning to play the angles.
Bald of Awesome: As Ultimate Nick Fury was based off of Samuel L. Jackson, he sports his actor's own bald dome.
Batman Can Breathe in Space: Fury had no problem rushing outside to the Helicarrier to stop the jet carrying the World Security Council's nuclear payload from hitting New York City whilst it had been at high altitude. Presumably the Helicarrier's earlier issues lowered its altitude considerably from the previously-stated 30,000'.
Big Damn Heroes: In his second Agents of S.H.I.E.L.D. appearance he pulls two - first helicoptering in to pull Fitz-Simmons out of the ocean at the last possible moment, second showing up in the nick of time as Coulson realises how badly he's outmatched by Garrett/Deathlok.
Crazy-Prepared: Very much so. As an example, his SUV has armor plating tough enough to resist sustained fire from automatic weapons and pneumatic battering rams, an AI for remote driving, medical supplies, a combination machine gun/grenade launcher between the front seats, and can fly (sadly, that function was broken). He also had a retinal scan of his bad eye taken just in case someone deleted the original one from the databases.
This persists in Agents of S.H.I.E.L.D.. He has off-the-grid facilities set up in the event S.H.I.E.L.D. is compromised, and has Coulson's badge embedded with the coordinates to one such base in case he might ever need to use it. He probably didn't predict Maria Hill betraying its location to the U.S. government in a misguided attempt to help Coulson. But it turns out he had another secret base, dubbed "the Playground.
Fury: You have become a problem; a problem I have to deal with. Contrary to your belief, you are not the center of my universe. I have bigger problems in the southwest region to deal with!
His reaction after hearing the mobile command station he requisitioned for Coulson was totaled:
Fury: Really? Really, Coulson? Six days? It only took you six days to take a completely renovated piece of state of the art machinery and turn it into scrap? Coulson: My team acted with my authority. Fury: Don't talk to me about authority. Do you know how much this plane costs? It's got a bar! ...a really nice one. Talking to me about authority; you know I have the authority to downgrade your ass to a Winnebago!
Deadpan Snarker: Much of his dialogue is a low tone snark. See elsewhere in this folder.
Death Glare: His general reaction to those he does not like, rather than shooting them. Not that that's any less deadly.
Dude, Where's My Respect?: Played with. While he does have the respect and loyalty of his subordinates, he does not have any from his superiors in the World Security Council, who constantly question his decisions, mainly his reliance on super-heroes or "freaks" as they call them, even though more often than not he's in the right and gets results.
Et Tu, Brute?: In the opening scene of The Avengers, when he was shot by Brainwashed and Crazy Hawkeye. He survives though, due to wearing a bulletproof vest. In The Winter Soldier, he's furious that his old friend Alexander Pierce has been part of HYDRA for decades. The real kicker is Pierce is the one who made Fury in charge of SHIELD.
Eyepatch of Power: The reason the director of an M.I.B. agency is wearing an eyepatch could fuel any number of fanfics. The state of the eye, although not how he lost use of it, is revealed in The Winter Soldier. The short answer is that it's not good at all, but it's still useful. He burns the eyepatch along with the rest of his property as he goes off the grid, substituting a pair of Cool Shades.
Faking the Dead: Fury is believed dead partway through The Winter Soldier after an assasination. Turns out he survived, though it was touch and go. At the close of the movie, Fury decides to continue pretending to be dead, so that he'll have more freedom to hunt down HYDRA remnants across the globe.
I Did What I Had to Do: Several times he takes unethical directions in performing actions he feels is right. Sometimes in big ways, such as authorizing plans for weapons of mass destruction powered by the Tesseract, to defend Earth from extra-terrestrial threats. Sometimes in small nudges, like Coulson's cards.
Maria Hill: Those cards, they were in Coulson's locker, not in his jacket. Nick Fury: [The Avengers] neededa push in the right direction. (sees the Quinjet takes off) They found it.
Ink-Suit Actor: An inversionenforced by the actor. Basically, when Samuel L. Jackson found out Marvel was using his image for the Nick Fury character, he cut a deal with Marvel Studios ensuring that he would be the one to play Fury if and when they started making works with the character.
Machiavelli Was Wrong: Invoked and averted. When Steve is concerned about the implications of Project Insight, Fury quotes The Prince, and says that S.H.I.E.L.D. deals with things as they are rather than how they wish they could be. Ultimately this mindset is shaken to the core at the end of The Winter Soldier when HYDRA leader Pierce reveals that Fury's pragmatic attitude towards world security is what inspired him to take a Knight Templar approach himself and join HYDRA.. It's pretty clear Fury is NOT proud of this development.
Trying to harness the power of the Tesseract led to an alien invasion of Earth.
Official S.H.I.E.L.D. policy is to throw any alien or too advanced technology into the sun. That turns out to be a lie; instead it's all hoarded in the Fridge. When S.H.I.E.L.D. collapses there's nothing to stop HYDRA from taking as much as they can.
Any super powered prisoners locked up? Turns out they're experimented on to enchance their powers. No, the agents are not told this, which makes things difficult for Coulson and his team when they have to recapture them.
Noodle Incident: According to Fury, the last time he trusted someone, he lost an eye. Exactly how he lost use of the eye is, as yet unrevealed.
Old Master: He was Coulson and Garrett's SO back in the day.
Only Sane Man: Much like his comics counterpart, he generally comes across as the only person with his mind together in most of his scenes. Interestingly for this trope, instead of (or in addition to) being a constant annoyance to him, he uses his perspective and bluntness to help people and/or situations reach their potentials. The Avengers shows that he even plays this role to the World Security Council, his bosses.
The Consultant reveals that in a world full of political power games, he and SHIELD are the only ones who are generally trying to handle the situation well.
Parental Substitute: Samuel L. Jackson mentioned this was the type of relationship Fury and Black Widow have. It's most obvious in The Winter Soldier when Fury seemingly dies and she is really stricken as a result.
Poisonous Friend: Could be considered this to Coulson, as revealed in Agents of S.H.I.E.L.D.. Coulson died after being stabbed by Loki, but Fury was determined to keep Coulson alive at any cost, regardless of how many surgeries it took or how much Coulson suffered as a result—analogous to pet owners who refuse to euthanize their pets. Taken further when we find out he had Melinda May filled in on the details and had her reporting to him to see if there were any side-effects. Then we find out the real reason for Coulson's team (and it was put together by May behind the scenes not Coulson) was to put him down in case of any ill side-effects. Then we find out that Coulson himself was the agent in charge of Project T.A.H.I.T.I. It was created in case an Avenger was seriously wounded, but Coulson was so horrified by the ill results of the project, he recommended it to be shut down, or he would quit S.H.I.E.L.D. Then Fury brought back to life anyway using T.A.H.I.TI.
Pungeon Master: Downplayed; he means these statements seriously, but he often makes puns alluding to his single eye, i.e. "Eyes on me", "You need to keep both eyes open", "I've got my eye on you", etc.
Retired Badass: The events of Captain America: The Winter Soldier and Agents of S.H.I.E.L.D. shake him up enough that he retires as Director of SHIELD and gives the position, and the job of rebuilding it, to Coulson, whom he believes best embodies the core tenet of SHIELD, protection of the innocent. However, he states that he'll still be out there helping out independently, or, in his words, he'll be everywhere.
Samuel L. Jackson: This Nick Fury is based on the Ultimate Marvel Universe's Nick Fury, who was specifically modeled after Samuel L. Jackson. Jackson being a big comic book fan, especially of Fury himself, he agreed for them to use his likeness, so long as he could play Ultimate Nick Fury if they ever made a movie with him. And sure enough...
World Security Council: Director Fury, the council has made a decision. Nick Fury: I recognize that the council has made a decision, but given that it's a stupid-ass decision, I've elected to ignore it.
Shout-Out: His tombstone in Winter Soldier has the first line of Samuel L Jackson's Ezekiel 25:17 speech from Pulp Fiction on it.
Unwitting Pawn: He, SHIELD and several other agents are revealed to have been this, with Fury being personally selected by the defacto boss of HYDRA, Alexander Pierce.
Well-Intentioned Extremist: A heroic version, as Project Insight was meant to identify and quell potential threats before they became real threats, despite the "gun-to-the-head-of-the-world" method of enforcement. However the people financing it had different objectives...
He had Coulson put in charge of Project T.A.H.I.T.I, originally created to heal or revive any seriously injured or dead Avenger, which turn out to have horrific side effects. How horrific? Coulson resigned as T.A.H.I.T.I. director and had it shut down. When he died, Fury went ahead and resurrected him anyway.
What the Hell, Hero?: Gets a lot of these from Captain America, Coulson, and numerous others due to his trust issues and morally ambigious ways of doing things. For instance, even though Coulson recommended that Project T.A.H.I.T.I. be shut down due to the horrific side-effects, Fury later had Coulson brought back to life using the same process.
Coulson: Stupid, stupid, stupid! And very cruel! And stupid!
"We get into a situation like this again, what happens then?"
By Captain America: The Winter Soldier, she definitely qualifies. She doesn't do as much as Natasha, but she does save Nat, Steve, and Sam from imminent execution, as well as very casually shooting two soldiers who were trying to sneak up on her, without even getting up from her chair.
By-the-Book Cop: This creates friction with her and Fury due to his more Military Maverick style, and several times she's filed reports to the WSC criticizing his actions. Even after she develops undying loyalty to Fury, she still retains this: notably she's not in any particular mood to join Fury or Coulson in their fight against HYDRA.
Call Back: During Agents of S.H.I.E.L.D. she says she's helping Stark "privatize global security" which connects to something Tony said back in Iron Man 2, only he said "world peace."
The Cynic: In contrast to the more idealistic Coulson. When S.H.I.E.L.D. goes bust, she seems more resigned to give up the fight against HYDRA, be content to work for Tony Stark, and play ball with the government as much as she can. Coulson stills prefers to fight on, even if he has no official support or sanction.
Despair Event Horizon: S.H.I.E.L.D.'s collapses seems to be this for her. She goes to work for Tony Stark; but she briefly joins Coulson in order to get Skye back, but that's it. She tells Couslon "there is no S.H.I.E.L.D. anymore" after he asks her for backup to go after the Centipede sector of HYDRA. She tells him he's on his own and goes back to her new civillian life.
Scully Box: It's hard to see in some shots, but Hill's boots have significant heel to them. Most likely due the fact that while Cobie Smulders is fairly tall at 5 foot 9, she's frequently next to Samuel L. Jackson, who's 6 foot 2.
Secret Keeper: She was one of the few people who knew Fury was alive from the beginning.
Spanner in the Works: Led the US military to Fury's secret base in Canada, interrupting Coulson's rescue attempt of Skye and denying his team any further use of it as a refuge.
The Stoic: She usually behaves quite seriously and professionally.
A member of the World Security Council and old comrade of Nick Fury. He commissions Captain America to fulfill his orders after Rogers' arrival in the modern world.Warning: Major unmarked spoilers for Captain America: The Winter Soldier below.
Actor Allusion: Casting Robert Redford in a political spy thriller is a big one all by itself, but more specifically, The Watergate Hotel is visible outside Pierce's office window. Robert Redford was in All the President's Men, a movie about the Watergate break-in that led to Nixon's resignation.
Adaptational Villainy: In the comics, Pierce is a standard, good guy agent. In the movie, he's not only the Big Bad of the second film, but also a part of HYDRA.
Adaptation Dye-Job: Comic Pierce has black hair, the movie version has Redford's natural red.
Age Lift: Pierce is a young man in the comics, somewhere in his thirties, and not even half of Redford's age.
Composite Character: Of Alexander Goodwin Pierce, as far as the name goes, Robert 'Rebel' Ralston, in being an old friend of Fury's who was in an oversight position over SHIELD, not to mention being actually drawn to look like Redford for a time, and Aleksander Lukin, the Winter Soldier's master. His motives and high position evoke shades of Number One of the Secret Empire arc.
Cool Old Guy: The fact that he's Robert Redford is reason enough, but he also argues defiantly with the World Security Council and has a good sense of humour.
His daughter, whose near death at the hands of terrorists was what motivated his Start of Darkness. When he saw how his inaction would've cost her her life and how Fury's unauthorized heroics saved her, Pierce decided he'd rather have the power to stop threats before they occur, whatever the cost.
He also expresses regret about the death of his maid, even though he personally killed her after she stumbled on his meeting with Winter Soldier.
Faux Affably Evil: At first, Pierce seems like another Nick Fury. He rails against the World Security Council much like Fury, has a friendship with Fury and is a fan of the Avengers. The reality is, he's a manipulative Jerkass who is a member of a dictatorial regime that was spawned in Nazi Germany and he himself is responsible for God-knows how many deaths over the years.
Hannibal Lecture: Gives one to Fury at the end of the movie, telling Fury that seeing his aggressive stance on terrorism earlier in their lives is what inspired Pierce to actively stamp out any and all threats to peace. Giving that meant joining HYDRA, Fury is noticeably upset at the notion.
When his housekeeper unexpectedly returns and stumbles onto his meeting with the Winter Soldier, he shoots her twice with only the most minor of regrets.
While trying to get a mission report from the Winter Soldier, Pierce slaps him in the face when he proves unresponsive, then has him subjected to a painful memory wipe, ignoring the Soldier's screams of agony as he walked away.
Knight Templar: Seems to genuinely believe that HYDRA's work is for the good of mankind.
The Man Behind the Man: The one who's pulling the strings of the Winter Soldier. He is also HYDRA's modern day leader.
Manipulative Bastard: He's been successfully manipulated SHIELD for years, and does a good job for manipulating the World Security Council, Captain America and even seasoned chessmaster Nick Fury.
Mole in Charge: Is a HYDRA plant within SHIELD. And he's basically Fury's boss. And after Fury's death, his control of SHIELD is essentially rock-solid.
The Needs of the Many: He justifies his plot to murder twenty million people by saying their deaths will save billions.
Non-Action Big Bad: Unusually for a superhero movie, Pierce does not appear to have any physical combat capabilities, aside from brief use of a gun. note although considering that fellow top S.H.I.E.L.D. agents Nick Fury and Maria Hill are both combat-capable, it is possible he may have some skills. However, given that he is in command of virtually all of S.H.I.E.L.D.'s resources (including legions of SWAT teams, multiple helicarriers, and The Winter Soldier), he is still extremely dangerous.
Obviously Evil: He frequently discusses his desire to create a new world, and the trailers prominently featured his line "Sometimes, creating a new world means having to tear the old one down. And that makes enemies". Does that sound like something a hero would say?
Remember the New Guy: Introduced as friend and superior of Nick Fury's, a member of the World Security Council, despite not appearing among them in The Avengers.
Running Both Sides: For most of The Winter Soldier, he's in charge of both SHIELD and HYDRA.
Well-Intentioned Extremist: Pierce apparently believes himself to be one of these, but it falls short when one considers that the intended targets of Project Insight were all people who stood to threaten HYDRA, rather than the world as a whole.
A secretive international group in charge of S.H.I.E.L.D. Nick Fury reports directly to them... but he doesn't always agree with them.
Character Death: Alexander Pierce executes three members of the council when they try to stop his plan. Only Ms. Hawley (Jenny Agutter) may still be alive.
Cosmopolitan Council: International Group. Out-of-universe, this is why the Pentagon didn't provide assistance during production.
Everyone Has Standards: Even they find Pierce's HYDRA scheme repellant. When Pierce gave one of them the hypothetical situation of their daughter being held at gunpoint by terrorists, about to be executed, and he could stop it with a flick of a switch, Pierce asks him if would. The member retorts, "Not if it was your switch."
Flat Character: The reason they all share one folder? We know nothing about them individually.
Fantastic Racism: They distrust the Avengers on the basis of them being an untested "handful of freaks". They also initially refer to Loki as merely "the Asgard", until Nick Fury corrects them. They also refer to Captain America as a "costumed mercenary".
In-Universe. The WSC wanted the Abomination on the Avengers instead of the Hulk, since they viewed Blonsky as a war hero and blamed Harlem's destruction on Banner. It takes a sneaky Batman Gambit from SHIELD to have their request for Blonsky to be denied.
Later, Steve Rogers finds they've been collecting old HYDRA tech, as they've been studying them so they too can create Tesseract powered weaponry.
Nuke 'em: They decide to solve the Chitauri problem with a nuke.
Straw Character: They exist to make Fury look right in spite of his Military Maverick attitude, most notably when they opt to immediately nuke New York rather than send in more military support, give the Avengers more time, or anything else.
Well-Intentioned Extremist: Firing at a nuke at New York city to halt the invasion. Their goal is to save the rest of the world but nuking is always extreme.
What Happened to the Mouse?: Councilwoman Hawley is not at the meeting in Winter Soldier that proves fatal for the other three members of the council; she is replaced by Black Widow in disguise. The whereabouts of the real Councilwoman Hawley are not revealed.
A key agent of S.H.I.E.L.D. and the only female Avenger. She kept surveillance on everyone from Iron Man to the Hulk, and is an extraordinary close-quarters fighter, but her determination to do good seems to come from the aftermath of an amoral past.
Action Girl: Aside from her intellect, this is her main power. While she has no superhuman abilities, Natasha is easily the most skilled hand-to-hand combatant in The Avengers.
Adorkable: In The Winter Soldier, she growls"Shall we play a game?" and begins to explain the reference to Steve (who, amusingly enough, already understood it). She also sends work-related text messages with smileys.
Affectionate Nickname: Clint calls her "Nat" in The Avengers, a sign of their more intimate relationship. Steve does it too at least once in The Winter Soldier, showing they've formed a close friendship.
Animal Motifs: Downplayed. Besides her alias, the only things referencing black widows are her weapon "Widow's Bite" and the red hourglass symbol in her belt.
Anti-Hero: Especially prominent in The Winter Soldier, where she contrasts with Steve.
The Atoner: Hinted at in The Avengers and made all the more evident in Winter Soldier. One of her main motivations for doing what she does is to make up for her past as an assassin ("wipe the red from my ledger", as she puts it) by doing good - and she legitimately believes that despite the amoral nature off her work working for S.H.I.E.L.D., as well as becoming an Avenger, is accomplishing that. She's legitimately distraught when she discovers that instead of doing good, all this time she had been doing HYDRA's dirty work instead, though in the end it shows a bit of character development that she's ultimately able to shrug off the possibility that every bit of her tainted past will become public knowledge.
Badass: Besides her extraordinary fighting skills, she's also an accomplished spy, thus she uses both fighting and cunning to defeat her enemies. Her badassery has even reached memetic levels in-universe, see Memetic Badass.
Badass Normal: A former assassin with gadgets, guns, good aim and even better close combat skills. That's still enough to qualify her as an Avenger.
Bad Guys Do the Dirty Work: As a former bad guy, she's more open to performing morally ambiguous actions. For instance, when conducting a High-Altitude Interrogation of Agent Sitwell, their captive scoffs at the possibility of Captain America throwing him off the edge. Cap admits he won't do it... but Black Widow will.
Bash Brothers: In The Avengers, she clearly has had this dynamic with Hawkeye for however long they've worked together, as shown in the movie's final battle and the footage from a previous mission.
The Chick: As part of the Avengers. Next to Steve Rogers and Bruce Banner (most of the time), she's the most levelheaded and put together of the team, and is constantly trying to encourage them to work together.
Child Soldier: Started working as a spy from a very young age. Would have been only 6 or 7 when The KGB was dissolved if the MCU goes by real time
Good Is Not Nice: In Iron Man 2 and in regards to Tony in general, with a tendency to try and make people back down when she thinks she ought to be dealing with something herself, seemingly more or less because Tony requires a more forceful personality around to keep him in check. Later, this becomes more of...
Good Is Not Soft: In The Avengers, she's rather respectful and polite to the people she has to work with - even Tony - and shows her lighter side more often, especially to Banner who she is assigned to keep tabs on. But she's also still extremely ruthless when it comes to doing what needs to be done, make no mistake.
Guile Hero: Her primary interrogation method is manipulating the egos of her targets to make them think they have her in a state of weakness, so they are more free while gloating. Just ask Loki.
Guys Smash, Girls Shoot: An inversion, at least when compared with fellow S.H.I.E.L.D. agent (and partner) Hawkeye. Natasha is a crack shot, but she's an even better martial artist.
Heel-Face Turn: She used to be a True Neutral assassin, but changed her ways after Hawkeye chose not to kill her when on a mission to do so.
Hoist by His Own Petard: Her M.O. Her interrogation techniques rely not on questioning someone, but on making them feel in control and letting them do their own talking. Her fights usually involve using something of her opponent's (the chair they tied her to, their own weapons, even their shadow) to make her moves.
Made of Iron: Takes a backhanded blow to the abs by the Hulk and gets up once her fear and shock wears off, with a limp for only short time. Then again, this could easily be pure determination at work.
Male Gaze: Her rear gets a lot of camera shots, especially in The Avengers.
Meaningful Name: Meta-example. The redheaded Natasha is played by Scarlett Johansson.
Odd Friendship: With Steve Rogers by The Winter Soldier. She's a chameleon-like spy and he's a straightforward soldier.
Older than They Look: Possibly. In the comics, she's nearly as old as Steve and on a less efficient version of the serum. Her birth year was stated as 1984 in the Winter Soldier, but the fact that she refers to having joined SHIELD from the KGB suggests that she was active during the Cold War.
One-Man Army: Tons of guards blocking the way to Vanko? No problem. Tied to a chair, surrounded by mobsters. No problem. Extra-dimensional aliens invading New York? Slightly more tiring, but still no problem.
The Stoic: Has a generally dour, serious demeanour.
Not So Stoic: Her run-in with the Hulk makes her lapse into a brief state of terror and she's shown sweating and trembling in fear more than any other member of the team. She admits to Hawkeye that "magic and monsters" are not something either of them were trained to cope with.
She also cries in Captain America: The Winter Soldier when she thinks Fury is dead. In a lighter example, she seems to have warmed to Steve by of that film, as she cracks a few jokes and makes film references.
Superhero Packing Heat: Has a pair of handguns on her, but she uses her hand-to-hand combat skills more often.
Territorial Smurfette: Subverted. Tony Stark expects this to happen with her and Pepper, but the two of them get along fine. Pepper takes it as a sign of Tony's arrogance that he'd assume another Love Triangle would form over him.
Undying Loyalty: Despite being a morally ambiguous spy, she has immense loyalty to Nick Fury and later, to Captain America fully willing to release every secret of SHIELD even her own complete file of all the good and bad things she did to the public so as to destroy HYDRA.
Waif-Fu: Her preferred combat style. In Iron Man 2, she blows through a building with a combination of non-lethal weaponry and improbable martial arts - all in the time it takes Happy Hogan to take down one guard with conventional boxing technique.
Why Did It Have to Be Snakes?: Noticeably terrified of the Hulk, which gives her an uncharacteristic lack of composure in his presence. Something Banner picks up on immediately. Worse still Natasha's fears actually come true when she finds an enraged Hulk rampaging directly at her and it's as scary as you'd image. No-one would really hold this against her.
Woman in Black: Her spy uniform is black in The Avengers and The Winter Soldier, and she qualifies as an Anti-Hero. Notably, after Tony finds out that she's the Black Widow in Iron Man 2, she starts dressing only in black in her Natalie identity too.
The Worf Effect: Somewhat downplayed but she falls victim to this against The Winter Soldier as she spends their entire fight running away from him, though she does sucker punch him several times. She is shown under much greater stress against him that she ever was against Loki or the Chitauri.
You Just Told Me: Her specialty. He favored means of interrogation is getting someone else to interrogate her, and their questions reveal their intentions and/or plans. Pulls this on the Russian smuggler and on Loki.
An agent of S.H.I.E.L.D., and the greatest marksman in the world. He recruited Natasha Romanov into S.H.I.E.L.D. instead of killing her like he was ordered, creating a bond between the two of them. He is assigned by Nick Fury to keep an eye on dangerous operations, like the Tesseract project.
The Ace: Considered to be the best marksman in the world.
Batman Can Breathe in Space: Much like Fury, Barton had no problem breathing in the attitude the Helicarrier was resided while invading with Loki's hired mercs, all of whom had gas masks on to breath normally.
Crazy-Prepared: Hawkeye has exploding arrowheads, hacking arrowheads, super-heating arrowheads, shrapnel arrowheads, grappling hook arrowheads, exploding arrowheads disguising to look like normal arrowheads so on the off chance the target has the Super Reflexes to catch the arrow they won't recognize it as an exploding arrowhead...
Deadpan Snarker: Once again we have a S.H.I.E.L.D. agent that loves pithy one liners. Moreso in his Thor cameo than The Avengers, however.
Hawkeye:[to Coulson regarding Thor breaking into S.H.I.E.L.D.'s facility] Do you want me to slow him down, sir, or or are you sending in more guys for him to beat up?
The Dragon: Brainwashed into serving as Loki's primary minion for the first hour or so of The Avengers.
Fashionable Asymmetry: Justified Trope, and more pragmatic than fashionable. Hawkeye wears an armguard on only his right arm (to protect from the bowstring) and a finger-guard on his left hand, (again, to protect from the bowstring).
Fighting from the Inside: Nick Fury suggests this in a deleted scene as the reason why Hawkeye shot him in the chest (right in his flak vest's metal insert), rather than the head.
Friendly Sniper: A consummate professional, but entirely approachable when off the job; even on the job, he'll toss off a dry wisecrack every so often.
Movie Superheroes Wear Black: Averted as it's based off his Ultimates incarnation. Somewhat played straight concerning his bow; Hawkeye primarily used a bright yellow longbow in the comics, until he gave it to KateBishop, to which he started used different coloured bows of many different designs. In the films, he uses a compound bow in Thor, and a collapsible recurve in The Avengers, both of which are coloured black.
Nice Guy: We haven't seen much of him outside of work, but he seems like a decent, friendly guy when he's off the clock.
No Arc in Archery: Usually, but averted when he fires one arrow at an angle that causes it to fly a curved route.
One-Man Army: Until he runs out of arrows he could bring down a battalion.
Out of Focus: Compared to his fellow Avengers. Barton has the least screentime out of the group in The Avengers; prior to that, only had a single scene cameo in Thor, and has yet to appear in the Phase 2 films. Compare to Black Widow, the only other character not to get a previous movie of their own, who is a supporting character in Iron Man 2, the second lead in Cap 2, and a major player throughout the Avengers.
The Stoic: When he starts firing at Chitauri gliders and Loki's on his own. Otherwise he's rather emotive, even friendly when not upset.
The Southpaw: Possibly. In his cameo in Thor, he pulls back on the bowstring with his right hand. In The Avengers, however, he pulls solely with his left and holsters his gun on his left hip. The comics Hawkeye is ambidextrous, but Jeremy Renner is lefthanded and Clint wears only one armguard (which is worn on the arm holding the bow).
Super Wrist Gadget: Like the comics he keeps the shafts and the heads of his arrow separate and his wrist guard helps control the distribution.
A (formerly) Level Six Agent of S.H.I.E.L.D., promoted over the course of the universe. Like Coulson, he is frequently sent across the globe to handle what Fury can't.
Adaptational Villainy: In the comics, he's a SHIELD agent through and through. In The Winter Soldier, however, he's revealed as an agent of HYDRA.
All There in the Manual: Until his story significance in The Winter Soldier, it's mainly in the shorts that he had any role at all.
Badass: We finally get to see it come Item 47. Sitwell captures Benny and Claire by moving into the hotel room next to theirs and playing extremely loud music so that they'll come over to complain. He then has to fight off Claire while struggling to handcuff her husband and while she tries to shoot him with an alien BFG.
Coulson: What's your clearance level? Sitwell: It's Level 6. Like you. ... Come on, there's a Level 7?
This is why he and Blake thought Coulson was still dead, because his survival was classified as Level 7.
As of Agents of S.H.I.E.L.D., he has been promoted up to Level 8 alongside Coulson, where... it's still part of the job description to be Locked Out of the Loop, solely because no one in Level 8 can know everything going on about the organization because it would be unsafe.
Knife Nut: He whips one out and... used it to cut Benny and Claire's bonds.
The Lancer: To Coulson. Following Thor he is frequently seen at his side.
The Men in Black: As a SHIELD agent he seems to fit the bill pretty well, looking into stolen alien technology and working to keep it under wraps.
Obfuscating Stupidity: He's says he does "a great patsy", and offers to do it so S.H.I.E.L.D. can sabotage General Ross's meeting with Fury. Turns out he really does, having tricked the majority of SHIELD.
Obsessed with Food: He has a tendency to bring up what the food is like at the places he visits during otherwise serious meetings.
Oh Crap: After he starts spilling his guts to Steve, Natasha, and Sam, Sitwell stops talking for a moment and remarks "Pierce is gonna kill me". Sure enough, the Winter Soldier kills him a few minutes later.
Pet the Dog: With the revelation that Sitwell is HYDRA, his sparing of Benny and Claire becomes this.
Though it becomes Harsher in Hindsight when you realize that Benny was involved in the R&D group that would design the helicarriers that HYDRA would use to kill 20 million people.
Screw the Rules, I'm Doing What's Right: After being informed of the World Security Council's decision to put the Abomination on the Avengers, he and Coulson start plotting a way to stop this. Given that Sitwell is HYDRA, he was probably more concerned that Blonsky was too unstable.
Suspiciously Similar Substitute: Of Coulson after his "death". While he's appeared beforehand in the films, Item 47 hinted he would take Phil's place as the everyman of S.H.I.E.L.D. Agent Blake even accidentally calls him "Coulson" due to force of habit. However, this was negated when Coulson was revealed to be alive. Ironically, in the comics Sitwell has been around since the 60's, whereas Coulson is a very recent Canon Immigrant, so you'd think it would be the other way around.
Wrong Genre Savvy: In regards to High-Altitude Interrogation. He thinks it's the version where the hero holds him over the edge, threatening to drop and he knows that Steve is too much of a Nice Guy to threaten an unarmed man like that. He's right, but the Black Widow isn't.
You Have Failed Me: Killed by the Winter Soldier for selling out HYDRA to Captain America and his allies.
Introduced in Marvel One Shots
"Your orders, Agent Sitwell: retrieve the weapons tech and neutralize the two outlaws."
An agent of S.H.I.E.L.D. in charge of surveillance. After Benny and Clyde get on the organization's radar due to their robberies, he tasks Sitwell with retrieving the alien Arm Cannon known as Item 47.
Amazon Chaser: Tries to flirt with May while they're on a mission.
Arbitrary Skepticism: Psychics? Pfft, nonsense. Astrology? There's something to that. May calls him on this.
Jerk with a Heart of Gold: Despite coming off as gruff and unpleasant he honestly tries to reason with Deathlok, promising to help free him if he'll call off his attack. In addition, while Sitwell is a HYDRA traitor, he is not.
The first thing he does when granted an assistant is tell her to make him coffee.
When given particularly difficult missions, his first reaction is to reach for more coffee.
The Men in Black: In charge of the retrieval of Item 47, though Sitwell does the field work.
Not So Stoic: He noticeably quiets up a bit when he accidentally calls Agent Sitwell "Coulson". It turns out even he misses him.
Obstructive Bureaucrat: In "FZZT" he insists that S.H.I.E.L.D. protocol be followed to the letter: if "infected cargo" is present on the Bus it has to be jettisoned into the ocean. Coulson's counter-argument that said "cargo" is a human being and fellow agent who still might survive her illness apparently has little impact on him.
Sinister Surveillance: He's technically on the side of good, but he comes across as rather sinister regardless.
