Break the Badass: Malekith's sneak attack on Asgard and killing Frigga shock the whole realm to its core.
Cool Airship: The Asgardians don't seem to use spaceships (since the Bifröst allows them to get anywhere in the universe faster and more easily), but they do use aircraft that look like flying Viking longships. With homing missiles and gatlingenergy guns.
A God Am I: Apparently something of a hobby. Go to Earth, cause a spectacle; fun for the whole family!
A God I Am Not: In The Dark World, Odin insists they aren't gods when Loki tries to claim otherwise. See Odin's section for more details.
Large Ham: The only one who doesn't get in on this is Hogun the Grim, though since it is shown in the second movie that he's actually Vanir, this trope does apply to all Asgardians.
Proud Warrior Race Guy: Space Vikings. They drink, they fight, they feast...and not much else. Big on honor and glory.
Really 700 Years Old: The battle against the Frost Giants took place in AD 984, and Odin led the charge. Fandral implies that Thor used to throw around lightning and thunder, and got worshiped as a god. The Dark World confirms that the average Asgardian lifespan is 5000 years. This probably includes Frost Giants as well, considering that King Laufey looks exactly the same as he does 1,029 years after the battle with the Frost Giants, and Loki appears to age at the same rate as Asgardians.
Screw Your Ultimatum!: In The Avengers, this appears twice. Both times, an Asgardian is asked to lay down his arms, and both times, the Asgardian flips out and attacks.
They freely mix magic and science. According to Thor's explanation to Jane, they think they're the same thing.
Jane: Like an Einstein-Rosen bridge? Thor: More like a rainbow bridge. Jane: God, I hope you're not crazy.
In The Dark World, Ein, tending to Jane, utilizes a "Soul Forge" to help heal her. She recognizes the device by referring to it in Technobabble terms as a quantum field generator.
Superior Species: According to the tie-in comics mainly, they seem to be the (mostly) officially-recognized defenders of peace in the universe. Since the Bifröst enables them to be anywhere at a moment's notice, fear of them is what keeps punks like the Jötunns, Trolls, Badoon, and Marauders in line. Which is why when the Bifröst goes down, all the evil races come out of the bushes and start wreaking havoc.
Super Strength: Part of their demigod physiology, being able to push humans off their feet.
We Are as Mayflies: A common Asgardian attitude, which both the films and Agents of S.H.I.E.L.D. touch on. It's difficult to see humans as worth concerning yourself over when the average human life span is a small fraction of your own.
World of Ham: A shiny world inhabited by many boisterous people.
The Norse God of Thunder, son of Odin, brother of Loki, and the heir to the Asgardian throne. He carries Mjölnir, the mythical hammer that only those deemed worthy can wield (or even lift) and enables him to command lightning. To teach Thor humility, Odin exiled him to Earth, where he met and fell in love with Jane Foster. Had an initially rocky encounter with Agent Coulson, but vowed his allegiance as an ally to S.H.I.E.L.D. He kept that vow by joining the Avengers and helping to defend Earth from Loki and the Chitauri.
Adorkable: He's painfully sweet, polite, and gallant to women, especially Jane.
Ain't Too Proud to Beg: To stop the Destroyer from causing destruction on Earth and hurting his friends, Thor not only apologizes for any wrongs he's committed but offers his life to Loki. This act of selflessness proves Thor's worthiness of Mjölnir.
"He's constantly having to battle for the greater good and what he should do, versus it's his little brother there."
Inverted in The Dark World, where he tells Loki he no longer considers him his brother and will kill him if/when he betrays Thor. Even here, he's devastated when Loki seems to die later, showing he still loves him.
Big Eater: Pretty common among Asgardians, but Thor himself ate an entire plate of food and then asked for more. Darcy remarked that he had already eaten an entire box of Pop Tarts before that.
Blood Knight: At the start anyway, he "courted war." Later on, he grows into a more noble man who sees combat as a way of protection, not a way of life.
Book Dumb: While by no means unintelligent, it's implied that his understanding of Asgardian technology is very basic (equivalent of C, π, E=mc2, etc.), and he is genuinely impressed that human geniuses such as Jane and Selvig understand underlying principles behind it better than he does. He brings this up in The Dark World; he states not that Earth will in some future era be Asgard's equal, or even that they're just a few generations behind, but that Jane will personally crack all the really interesting secrets of the universe within the next decade at most, making humans Asgard's equals.
Boisterous Bruiser: He starts off a battle-seeking brat, but wises up and settles on this.
Break the Haughty: Thor's banishment serves this purpose in the first movie. He is unable to lift Mjölnir and learning, through Loki's deceit, Odin is dead and his mother has condemned him to exile. It becomes a reconstruction after spending time on Earth and learning from his mistakes.
Bruiser with a Soft Center/Emotional Bruiser: For all his boisterousness, he shows plenty of emotional vulnerability. After Loki claims Odin is dead, he first simply asks "Can I come home?" When told he can't ever return to his family, he thanks Loki for coming to say goodbye. When he confronts Loki in The Avengers, the only times when his grin cracks are when he's begging his brother to come to his senses.
Brought Down to Badass: Stripped of his godlike power, he's still a very, very skilled and experienced combatant who's made of muscle. Coulson tried to recruit him before he learned of the god-like power he possessed based solely on his skill.
Genius Bruiser: He's pretty clever once he develops some restraint and consideration, such as putting Mjölnir on Loki so that he can't get off the ground, and then smashing the Rainbow Bridge to topple the Bifröst at the other end.
Genre Blind: Initially his trusting and hot-headed nature makes him prone to obvious mistakes, such as constantly mistaking Loki's illusions for the real guy.
Gentle Giant: Thor is a mountain of jolly muscle who loves and protects the friends he towers over.
A God Am I: Technically, he is a god. At the start of his own movie, he fits the trope, as he believes he can subdue Jötunheim by barging in and taking a few thousand of them down, but by the end, he's humbled and a man of sincere duty and honor.
Good Is Not Soft: He's an immensely likable and fun guy who will smash your face in with a hammer if you threaten Earth or Asgard.
Heartbroken Badass: If having to fight his little brother and then believing him dead in Thor wasn't enough, he loses his mother and apparently Loki again in The Dark World.
Helmets Are Hardly Heroic: He only dons his trademark winged helmet in his first scene as an adult, and even then it's mostly for ceremonial purposes. Being so durable, unlike the other helmeted Avengers, he doesn't need it.
Hot-Blooded: Thor is quite exuberant, wearing all of his emotions on his sleeve; this makes his Heroic BSOD all the more noticeable, as after everything falls apart for him, he closes up entirely.
In The Avengers, he categorically states that he considers Earth under his protection after Loki mocks him for begging Odin to let him return to his adopted home. Later, he privately admits to believing that while his people are clearly more advanced than humanity, that doesn't make them better.
Hunk: He's ruggedly handsome and his wardrobe on Midgard fits the description above exactly. He has an Shirtless Scene, later followed by mud-wrestling in a tight, rain-soaked T-shirt. This makes him a perfect foil to Loki's Pretty Boy looks.
I Gave My Word: If Thor gives his word about something, he will honor it.
Immortal Immaturity: Thor is, in all likelihood, 1000 years old, and yet it is only in the three days he spent as a mortal that he starts to emotionally mature.
Irony: As the second step in his Humiliation Conga (after being hit by a car not long after landing in Midgard), the God of Thunder is taken down by...a taser.
Jacob and Esau: Thor is the Esau to Loki's Jacob. Despite Odin's protests, he favors Thor over Loki.
Jerk with a Heart of Gold: In his first film, he's an unstable, entitled hothead who rarely thinks before acting. He is also extremely noble, very respectful towards women, loves his brother and friends, and always keeps his word.
Large Ham: His bombast is helped by talking in flowery English. ("This mortal form has grown weak. I need sustenance!")
Lightning Bruiser: In more than one way. He's fast and agile enough to dance around the Hulk, and can fly at mach speeds while equally matching Hulk's strength, one-shot-ing Frost Giants and (though it isn't obvious at first) easily overpowering Tony's armor, even after it's been supercharged and he's holding back.
Man Child: Even after his Character Development, Thor is still endearingly naive when it comes to how the rest of the multiverse outside Asgard works, and readily admits to his father that he still has a lot of growing up to do at the end of Thor.
Mayfly-December Romance: With Jane; it's brought up several times that human lifetimes are extremely fleeting compared to Asgardian ones.
While all of the male Avengers are at least good-looking, Thor is thus far the only one whose hunkiness has hit in-universe memetic levels. In Agents of S.H.I.E.L.D., both Skye and Agent Melinda May describe him as "dreamy." Even Maria Hill has noticed:
Ward: I don't think Thor is...technically a god. Hill: Then you haven't been near his arms.
Nice Guy: After Character Development sets in, he pretty much loses the "jerk" part and gains wisdom and patience in addition to his other good qualities.
Nice Job Breaking It, Hero: Odin warned him that bringing Jane to Malekith would basically be handing his enemy a nuclear bomb should he fail to destroy it once it's pulled from her, but he does it anyway and Odin is proven right.
One-Man Army: He slaughtered dozens of Frost Giants single-handedly and accused them of not trying hard enough. He also is the only Avenger not to be pinned down or in serious trouble during the Battle of New York, even after being sucker-punched by the Hulk.
Out of Focus: Since the Big Bad of The Avengers gives him a personal stake in the conflict (as he is both family and attempting to abuse Asgardian technology), they had to write him into the movie with a lighter touch than the other characters so it wouldn't boil down to Thor and Those Other Guys.
Perpetual Smiler: Thor is almost always cheerful, even in the middle of a fight to the death with an army of Frost Giants; this, alongside his vainglorious optimism, is seen by many as a symptom of his childishness. By the end of the movie, he learns to be truly serious about things and becomes more solemn as a result. While he does make jokes in The Avengers, this facet of his personality has not truly returned, as he is serious in any truly serious situation.
Perpetual Frowner: During battles he might be cheerful, but he is certainly scowling.
Physical God: Literally, which is part of why it's very hard to hurt him seriously when he's at full strength.
Red Is Heroic: Wears a long, flowing red cape to emphasize his heroic personality.
Red Oni, Blue Oni: The Red to Loki's Blue in that he is boisterous, passionate, and very strong. He mellows for The Avengers and by the time of The Dark World, Loki gleefully points out that sneaking out of Asgard for a Batman Gambit instead of "punching his way out" is "so unlike you, brother."
Royal Brat: In the first movie, Thor starts out spoiled and selfish, willing to throw two realms into a long and bloody war to prove himself. He expresses his rage by bellowing and shoving a large dinner table (along with its contents) to the floor.
Sibling Rivalry: With his little brother Loki, although he doesn't seem to take it anywhere near as seriously as Loki does.
Super Strength: Has shown more of this than any other Asgardian. Strong enough to smash through metal walls, match blows with the Hulk, block an overhand strike from him, and crush Iron Man's Mark VI armor with his bare hands. With Mjölnir, he's smacked a car down the street, sent Hulk flying, and leveled a good chunk of a forest with the shockwave of the blow.
Took a Level in Kindness: The whole point of his first movie, which is an inversion of Steve's. Whereas Captain Rogers was granted power because of his kindness and decency, Thor had to learn kindness and decency first to be worthy of his power.
With Sif. Intentionally done by the writers, since the people who worked on the film wanted to be able to have the option of writing Thor/Sif into the sequels, should they later want to.
Jaimie Alexander: But there is a reason that we sort of subtly hinted to it in the first film. Just so that there is a door. If we want to go through that door, we can. They like to cover all their bases at Marvel.
During an interview, Chris Hemsworth referenced this when speaking about their relationship in the second film, as well as what it was throughout the first movie.
Chris Hemsworth: In the comic books, there's obviously an attraction with Thor and Sif, or what have you. And there was little peppering of that, I think, in the first one. Little hints at it. There (in The Dark World) may be...might be more indication...
One of Mjölnir's primary powers from the comics is to allow the wielder to transport himself and anyone he wishes across dimensional boundaries. He doesn't need the Bifröst, though for the sake of propriety, he does usually cause himself to appear at the point on the bridge where Heimdall keeps his watch. Obviously, this is a bit of a Story Breaker Power in the movies, given that they want travel between the Nine Worlds to be something more than the trivial matter it is in the comics.
When He Smiles: Although already a boisterous and jovial fella, Thor's face positively glows with an endearing warmth and kindness when he is genuinely happy and at ease.
Worf Had The Flu: Possibly in The Avengers. The Prelude to Thor: The Dark World implies that there is a cost to Odin and Thor's health when the Allfather summons dark energy to transport Thor to Earth. Odin is almost instantly hospitalized and Thor himself crashes to Earth in spectacular fashion, with Sif wondering if he even survived the trip. This puts his fights in the film into a new perspective.
Worthy Opponent: After getting swatted aside by the Hulk in The Avengers while trying to restrain him, an enthusiastic grin creeps across his face and that says it all.
The Norse God of Mischief and Lies, and Thor's younger brother. After a bid to discredit his brother and destroy their enemies in Jötunheim backfires, he plunges into an abyss where he gets transported to another realm. He is given an army and the promise of absolute rule over the people of Earth if he can subdue them and turn over the Tesseract, a piece of Asgardian technology residing on Earth, to his employers.
Ace Pilot: He claims he is this and proves to be pretty good on a Chitauri skiff he commandeers during the Battle of New York. Thor disagrees.
Loki: Look, why don't you let me take over? I'm clearly the best pilot. Thor: Is that right? Out of the two of us, which one can actually fly?
Adaptational Attractiveness: Loki in the movies is far more attractive than his comic book counterpart who was, at least during the early days, often depicted as being hideous. By the eighties, he was usually depicted as good-looking to one extent or another.
Affably Evil: Always holds himself to a regal standard of conduct as he believes himself to be the true inheritor to Asgard's throne. Even after his (literal) fall from grace, Loki never lets his circumstances shake his aura of class and nobility.
Annoying Younger Sibling: In The Dark World, he knows how to get under Thor's skin, irritating the heck out of his brother with his shapeshifting pranks and his snarky comments about Thor's piloting skills during their escape from Asgard.
Anti-Villain: His actions early on in Thor are that of a trickster causing some potentially dangerous mischief and accidentally causing more trouble than he intended, then later he purposefully begins hatching amoral and destructive plans. In The Avengers, he's drops the "Anti" part and is a straight villain.
Arch-Enemy: To Thor. It's the "We're brothers!" angle that makes the conflict so personal and the conflict so epic.
Badass: Though he's outmatched in physical combat by most foes, including his brother, he's still a master of magic, a competent hand-to-hand fighter, and is able to kick his fair share of ass in his own right.
Since he studies magic, he's the Asgardian equivalent of a "nerd."
Reading also appears to be his pastime of choice while imprisoned in The Dark World—not that he has lots of options in an (albeit fairly cushy) dungeon, but he appreciates the books given to him by Frigga, and one can't really imagine most of the other Asgardians calmly reading while there's a battle erupting around them.
Badass Longcoat: In The Avengers, although he sometimes goes back to his royal outfit.
Beauty Is Never Tarnished: Oh so averted in The Dark World, although it doesn't appear that way at first. Loki in his prison cell is groomed, relatively well-dressed and has nice furnishings. When Thor comes to bargain with him after Frigga's death, he breaks the illusion to reveal a dirty, pale, unkempt man in rags surrounded by smashed furniture and smudged walls. His foot is even bleeding severely.
Beware the Quiet Ones: In Thor—in sharp contrast to the other citizens of Asgard who are loud and boisterous, Loki is initially soft-spoken and quiet.
Big Bad: In Thor, he's an Anti-Villain example, but is a straight-up villain for The Avengers where he steals the Tesseract to take over Earth, but even then, he's simply delivering the Tesseract to Thanos in exchange for Earth.
Blade on a Stick: While Odin is in the Odinsleep, he uses Gungnir as both a scepter and a weapon.
Blatant Lies: When Frigga asks, "Am I not your mother?", Loki hesitates for a full five seconds before he unconvincingly replies "You're not." The sad expression on his face and his reaching out for her hand afterwards prove that he doesn't mean it.
Bling of War: His green-and-gold armor is magnificent to behold. It's more stylish than Thor's or Odin's, which is not surprising considering that Loki is a master of deception, so appearances are important to him.
Blue Blood: No matter how you look at his family ties, he's a prince of something.
Boomerang Bigot: Growing up in Asgard, he was raised to fear and hate Frost Giants, so when he accidentally discovers that he is one, he is consumed by so much self-loathing that he attempts to wipe out every Jötunn in existence.
Boom Stick: His scepter in The Avengers fires blasts of blue energy, said to be using a similar type of blast as HYDRA's weapons in Captain America.
Break Them by Talking: Averted in Thor when he wasn't trying to break anyone, but he really gets into it during The Avengers. Nick Fury, a crowd of Germans, Black Widow and the Hulk all get one.
Breakout Villain: He's the only villain to get a continuing role beyond his original film, and is so popular that the film crew of Thor: The Dark World shot extra scenes of his character. Given that he was the Big Bad of The Avengers, arguably one of the most anticipated films of all time, he is unquestionably the franchise's most famous villain by this point.
Broken Bird: Learning about his true heritage messed him up, and then falling into the abyss made it worse.
Butt Monkey: Despite being the Big Bad of The Avengers, Loki seems to have a few spells of being one of these during the movie, especially towards the end of the film. Every Avenger gets his goat once. Even Phil Coulson gets in a good shot.
Cain and Abel: The Cain to Thor's Abel complete with envy and (attempted) murder.
The Chessmaster: He orchestrates all the events of Thor from behind the scenes.
Color-Coded Characters: His royal outfit is green, gold and black, and his hair is also black. Thor, on the other hand, has blond hair and wears blue, red and silver.
Complexity Addiction: In Thor, he can't help lying to and betraying people even if it wouldn't help him, or if it wouldn't be pragmatic to betray them yet. Likely related to his Inferiority Superiority Complex—he has to prove how much smarter he is than everyone by deliberately manipulating them as much as he can and gloating about how he did it.
Consummate Liar: Comes with the territory of being the God of Lies and Mischief. Lampshaded when Thor notes he's always been a talented liar. This is right before Loki said he was glad to see Thor.
Death Glare: In the first movie, Loki gives a menacing one to Sif in the throne room while he leans slightly forward in her direction. His eyes and body language seem to say, "I dare you to talk back to your king."
Death Seeker: Both Sif and Volstagg threaten to kill him if he ever betrays Thor again. Doesn't make him flinch at all.
Deuteragonist: After Thor himself, the villainous Loki is the most important character in the Thor films.
Didn't Think This Through: He never considers the difficulties involved in conquering, pacifying and occupying Earth. He thinks if he just brings in an army, the humans will fall in line and submit to him, ignorant of Earth's military forces, the members of the Avengers and who-knows-what-else including the other Asgardians, that will want to have words with him once the Chitauri leave. Even if his invasion succeeded, it never would have lasted. Lampshaded by Tony.
Tony Stark: You're missing the point! There's no throne. There is no version of this where you come out on top. Maybe your army comes and maybe it's too much for us, but it's all on you. Because if we can't protect the Earth, you can be damn well sure we'll avenge it.
Disproportionate Retribution: His plot to take control of Earth in The Avengers is largely driven by jealousy and resentment towards his adoptivebrother Thor, as well as rage at being deceived about his true ancestry. He wants to subjugate the entire population of Earth—a planet which Thor treasures and protects—thereby wiping out many of the people that Thor cares about. In addition, Loki feels that he was cheated out of his rightful place as the ruler of Asgard.
Thor: So you take the world I love as recompense for your imagined slights?
Dissonant Laughter: He's seen giggling, if not outright laughing, in clear contrast to his tumultuous emotional state, but in different ways:
In the climax of Thor, it's used as a unnerving instance of Laughing Mad—it represents him being so lost that his emotions are all over the place, and in conjunction with his increasing mood swings, shows that he's losing his mind.
In contrast, The Avengers uses it as one of the only real signs of his softer traits. Loki attempts to cover up situations and feelings that he would rather not acknowledge (like Thor's repeated attempts to reach out to him) with quips and nervous, often dissonant Mirthless Laughter. He also uses it as a show of bravado in the face of being surprised or intimidated.
Dissonant Serenity: Practices this from time to time. In The Dark World, he watches calmly as Kurse frees the other prisoners while waiting for him to make his way to his own cell. When Kurse leaves him locked up, Loki is later seen quietly reading while sitting against the wall, even as there's a massive brawl a foot away on the other side of the force field.
Driven to Suicide: He lets go of the Bifröst by the end of Thor, but as explained just above, he survives.
His Evil Plan in Thor was all about proving himself to his father Odin. However, he couldn't care less about his biological father Laufey, as he killed the man and then tried to blow up his planet.
Even after his descent into madness, he continues to love his mother Frigga. Aside from rage, this is the only genuine emotion he has left by the time of Thor: The Dark World.Her death at the hands of the Dark Elves helps to motivate him. In his first scene, Loki puts on a contemptuous facade, but his mask slips when Odin informs him that he will never see Frigga again; he then stumbles as he's being led away by the guards.
Even Evil Has Standards: In a strange sense in that it overlaps with Kick the Dog—when Thor tells Loki killing the humans will bring him nothing and offers his life if he spares them, Loki kills him, but the Destroyer turns and start to leave, so Loki was keeping true to his side of Thor's deal.
Fake Defector: In The Dark World, he magicks up an illusion that he cut off Thor's hand and roughly hands Jane over to Malekith, but this was all a ploy to lower Malekith's guard and get the Aether in the air so Thor could destroy it.
Fallen Hero: It goes without saying that Loki more than likely fought alongside Thor, Sif and The Warriors Three in countless battles and adventures, performing innumerable deeds of great valor and sharing the glory, wine and laughter of victory with his now-former friends.
Faux Affably Evil: Temporarily turns into an insane sadist after falling into an abyss at the end of Thor, while still keeping his affable demeanor. The sadistic streak wears off by Thor: The Dark World.
Loki:[to Natasha] I won't touch Barton. Not until I make him kill you, slowly, intimately, in every way he knows you fear. And then he'll wake just long enough to see his good work. And when he screams, I'll split his skull.
Genocide from the Inside: After Loki finds out that he is actually an abandoned Frost Giant prince adopted by Odin, he murders his biological father and tries to exterminate his own race to prove himself a worthy prince of Asgard. Odin is absolutely horrified.
Glamour Failure: Whenever he comes into contact with the Frost Giant's power, his true heritage shows.
A God Am I: Styles himself as the God-King of Earth in The Avengers. While he has some basis to claim this, he is the only Asgardian that puts on airs.
Go Mad from the Revelation: Learning of his true parentage causes any jealousy and insignificance he feels towards Thor to explode into full-blown madness driven by his desire for acknowledgment from Odin.
Happily Adopted: The fact that he's not their "real" child has no effect on Odin, Frigga, or Thor's love for him, nor on his for them.* He does use it as an excuse for trying to kill Thor several times, but it seems likely that's because he's been harbouring resentment towards him for centuries, not because he finally learned they weren't real brothers. The only thing that changes when he learns the truth is his perception of their love for him, with tragic results.
Hannibal Lecture: During The Avengers, he tears into Black Widow while imprisoned on the Helicarrier. It must run in the family.
The Heavy: In The Avengers, he's an errand boy retrieving the Tesseract for Thanos and ordered around by The Other.
Heroic Sacrifice: He is nearly sucked into a mini black hole after he pushes Jane away from the grenade's path in The Dark World; Thor saves him in the nick of time. Loki then appears to have died defending his brother from Kurse's brutal beating, but it turns out that the stab wound he received wasn't fatal.
Inferiority Superiority Complex: He chooses to deal with his crippling self-worth issues by trying to blow up/subjugate worlds. If you want to see him lose his cool, try challenging his power and/or authority and watch him shout you down with declarations of how great and powerful he is. This is particularly evident in several scenes in The Avengers; the less control he has, the louder and angrier he becomes.
I Need a Freaking Drink: Tony offers Loki a drink, which he rejects. After his defeat, he decides to take him up on his offer.
Insane Troll Logic: Loki's motivation in The Avengers follows as this—He wants to conquer Earth, because if humans are too busy worshiping him, they won't be fighting any wars. He never really figured that they just might be warring against him. Thor calls him out on this during the final battle in New York, but he doesn't care.
Sure, he ruins Thor's big day for "a bit of fun," but he also did it to reveal how unfit to rule his brother was in Thor. He does eventually become the villain, but at the time, he spared Asgard a massive headache.
In The Dark World, he points out that Thor will outlive Jane by a very long time.
Also in The Dark World, when confronted about his crimes, he points out that both Bor and Odin technically killed many more people than he to preserve peace in the Nine Realms. Considering Bor all but exterminated the Dark Elves, he has a point.
Kick the Dog: Though it was in his interests to convince Thor his exile was going to be permanent to maintain a new truce with the Jötunns, telling him Odin died due to the stress of exiling him was just cruel.
Kneel Before Zod: Commands this to a crowd of civilians, and later Captain America, when he appears in The Avengers. The civilians obey—with the exception of two men, both of whom lived through WWII. One is an elderly German man, the other is Captain America.
Knife Nut: Uses small throwing daggers (their effectiveness can be enhanced with magic) to attack from afar in Thor and The Avengers, and fights with a single longer one in The Dark World.
Made of Iron: This seems to be the case for Asgardians and Frost Giants in general. Though considering that he survived being stabbed in the chest, while Frigga the queen of the Asgardians didn't, it's possible that Loki is more durable than the average Asgardian or increased it with his magic abilities.
Magic Staff/Magic Wand: His Chitauri scepter in The Avengers. Its normal size is "wand", but when he dons his royal outfit its becomes longer with a larger blade and is used as a staff.
Manipulative Bastard: As noted elsewhere on this page, he manipulates everyone he comes into contact with to prove how smart and in control he is of any situation.
In the first movie, Loki's face is visibly wet with tears after he discovers from Odin that he's actually a Frost Giant. He also sheds a tear when he asks Thor, "Is it madness?", which is a sign of his emotional breakdown.
In The Avengers, Loki displays a rare moment of vulnerability right after he stabs Thor. A tear falls from his eye as he says, "Sentiment."
Inverted; while he has strength and magic he relies on power gained from elsewhere rather than his own strength. In Thor, he uses Odin's staff and the Destroyer, and in The Avengers he relies on the Chitauri staff, mind-controlled heroes, and an alien army. This forms a contrast with the heroes whose power comes from their inner strength and qualities (Cap, Banner) or something they made themselves (Stark). This reliance on external power despite claiming superiority could be a sign of his insecurity.
He abandons this trait by The Dark World, where he's never armed with more than a dagger, his powers of illusion, and his innate guile. What this indicates is open to interpretation.
Master of Illusion: Though this was the gimmick of a different figure in mythology, movie Loki is fond of using illusionary copies of himself to distract his enemies, and to taunt them. By The Dark World he's expanded his control over it into functional shapeshifting, able to cloak himself or others to look like other people.
Mirthless Laughter: Loki is always laughing and chuckling, even when angry or sad; and it makes him all the more creepy.
Momma's Boy: Frigga seems to be the only member of the family that Loki can tolerate after all that's happened. Which makes seeing his reaction to her death even more crushing. He is also shown to be his mother's son to a certain extent, as Frigga is the one who taught him magic, and his combat style in The Dark World is very similar to hers.
Moral Event Horizon: An In-Universe example in The Avengers with his tactics in trying to take over the Earth. How cruel were those tactics? Odin has him doing porridge for life (and would've had him executed if Frigga hadn't intervened); Thor, Sif, and Volstagg threaten to kill him if he betrays them; and Jane slaps him in the face.
Never My Fault: Loki doesn't take responsibility for his actions, and he doesn't believe he did anything wrong when he attempted to conquer Earth.
Nice Job Fixing It, Villain: He gets Thor exiled from Asgard by setting things up to show that his brother isn't worthy of taking their father's throne. In doing so, he humbles Thor enough for him to become worthy. Sending the Destroyer after him gave him a chance to prove it.
Nominal Hero/Token Evil Teammate: In The Dark World, his reasons for helping Thor defeat Malekith are fairly selfish, but he nevertheless puts his life on the line to achieve their mutual goal.
Non-Action Big Bad: A more subtle example than most. While he is technically well above any mortal in physical prowess, he isn't quite up to par with Thor in combat, preferring to compensate with his intelligence and cunning. As such, he tends to use trickery to avoid direct conflict. This changes in The Avengers, where he is willing to dirty his hands against S.H.I.E.L.D. agents that are no threat to him and proves Captain America's superior during their short battle.
Redemption Rejection: When Thor is still willing to offer Loki a chance as the Chitauri attack New York, he seems to genuinely consider it...then shanks Thor with a throwing knife.
Red Oni, Blue Oni: The blue to Thor's red as he is more a shadowy presence meant to manipulate and confuse, but he still has Asgardian hamminess.
Reliable Traitor: While Thor seeks his help in The Dark World, everyone including Thor himself is quite aware Loki is going to betray him eventually. They even use this to their advantage when tricking Malekith into exposing the Aether. Loki doesn't betray Thor, but he does trick Thor into thinking he died while he goes into hiding via shapeshifting.
The Resenter: A seething ball of jealousy from his first scenes onward.
Although this is not explicitly stated in the first movie, it's quite obvious that part of the reason why Loki wanted to kill Laufey is to get back at his biological father for leaving him to die as an infant.
After Frigga is murdered in The Dark World, this becomes Loki's motivation to team up with Thor to stop Malekith.
It is also clear that he would like to get back at Odin, though the ambiguity of the last scene makes it unclear as to whether he actually has.
Royal Brat: Like Thor, Loki has overtones of this. He has no problem getting guards and Jötunns killed for the sake of a prank on his brother.
Sanity Slippage: Falling through a rift in space at the end of Thor did nothing good for his mental health. Not that it helps his case when he's faced with the consequences of his actions in The Avengers
Self-Made Orphan: He kills his biological father Laufey while declaring himself the son of Odin. It looked like he was about to kill his adoptive father in an attempt to appeal to his biological father, but then he kills his biological father in a (completely misguided) attempt to appeal to his adoptive father. Wow.
Self-Serving Memory: In The Avengers, he claims that Thor threw him into the void, apparently forgetting that he chose to fall in after Odin refused to condone Loki attempting genocide in his name.
Sharp-Dressed Man: When he appears before the imprisoned Thor in Midgard and when he attends Loge in The Avengers.
Stepford Snarker: Though not so much at first, by Thor: The Dark World he is this. A few unguarded moments show that he actually still does care (at least about Frigga, though possibly about Thor and his former friends too) but he spends most of his time among other people, especially the Asgardians, snarking at them to cover up both this and his pain that they now (at least seem to) hate him.
Sufficiently Advanced Alien: Like all Asgardians though he is also known as a "master of magic" which makes things a little complicated.
Black Widow: These people come from legend. They're basically gods.
Suicidal Cosmic Temper Tantrum: Ever since discovering his origins, Loki has been subtly throwing one. All bets are off in The Avengers when he clearly becomes fed up.
Super Strength: Like his Asgardian peers, though not quite to the same extent due to his focus on magic. Most evident in The Avengers, where he kills a normal man in body armor with a single kick and throws Captain America around like a ragdoll.
Technically a Smile: Loki never loses that confident grin of his, which widens into a leering, arrogant, wolf-like sneer when he's enraged; and it's easily the scariest expression he's got.
There Are No Therapists: Everyone seems to agree that Loki's got a few screws loose. No one seems to think he might benefit from medication or psychoanalysis.
This Is Your Brain on Evil: When he arrives in The Avengers, he's a sweating, pale, sunken-eyed mess. This is our first clue that something has gone wrong in his time away. The second is the way he casually murders several soldiers before deigning to speak.
Going through a wormhole gave him one hell of a steel edge. He was initially relatively badass, being a God and all, but by The Avengers, is considered to be exponentially more dangerous. Tom Hiddleston invoked the trope when discussing Loki in The Avengers
Loki's a stronger melee fighter in The Dark World than in his previous appearances; here he was armed with only a simple dagger and took on several foes at the same time. In the past, he relied on throwing magical "knives" from a distance, his illusion spell, or a powerful scepter, and he usually focused on one enemy at a time.
As Crackedpointed out, he went from being a Chessmaster and Manipulative Bastard in Thor to being perpetually fooled and outsmarted by virtually every member of the main cast in The Avengers. They summed it up with "Loki, the Silver-Tongued God of Deception, Can't Outsmart Anyone". However he still played Divide and Conquer against the Avengers before they rallied together for the grand finale and it could also be said that the Tesseract was driving him crazy and causing him to be power hungry at the expense of long term planning.
As demonstrated by the ending in Dark World where he's sitting on Odin's throne, carrying his staff, and pretending to be him with Thor none the wiser it is easy to state that any level he took in Avengers is gone.
Tragic Villain: In Thor, where his villainy was well-intentioned and his goal was familial love.
Troll: He is the God of Mischief and Trickery, after all. In both Thor films, he uses his powers for pranks, such as shapeshifting himself and Thor just to irritate him, and after his fall to villainy, his demeanor is generally one of mocking snark and arrogance.
Laufey: So you're the one who showed us the way into Asgard. Loki: That was just a bit of fun, really. To ruin my brother's big day.
The Unfavourite: He sees himself as such. He definitely doesn't fit the ideal of Asgard the way Thor does, but Odin repeatedly assures him "you are my son" and had great plans for him just as he did for Thor. He hoped that Loki would pioneer a lasting peace and friendship between Asgard and Jötunheim instead of the fragile truce present at the time.
Used to Be a Sweet Kid: The scene with young Loki shows him and Thor being absolutely adorable as they listen to Odin telling them a story about the war with the Jötunns.
Starting around the time he discovers he's a Frost Giant, and getting progressively worse throughout the rest of Thor. This does not make him less effective, however - his growing insanity coupled with his deadly cunning only makes him more dangerous.
Villain Protagonist: In both of the Thor films, he shares the protagonist title with Thor, but the first more than the second. In the first he had his own scenes and own plotlines. In the second he spends too much time in his cell to fully qualify.
Waif-Fu: A borderline male example—he's played by 6' 2", ordinarily-slender Tom Hiddleston, but made up and costumed to look outright skinny—and still capable of at least briefly beating his beefy brother in combat (including, notably, using his father's scepter/spear as a pole to propel his body around in order to increase his momentum for a kick in the face).
"Well Done, Son" Guy: Even though he is furious that Odin lied to him about his parentage, his ultimate goal is still his love and approval rather than his throne. In The Avengers he's still driven by a need for validation and approval, but doesn't want it from Odin specifically, just in general.
Well-Intentioned Extremist: Part of the basis for his motivations in Thor. According to Word of God, he's this in The Avengers as well, as Loki thinks conquering the Earth is a grand idea to bring about peace, since everyone will be too busy bowing to him to fight amongst themselves anymore.
When He Smiles: Surprisingly, albeit in a deleted scene in Thor. Even if you doubt his motives for going with Thor, it's one of very few scenes where he looks genuinely happy about something (if only for a few seconds). And damn does he look adorable.
Thor: Thank you, brother. Loki: (beat)[smiles] Now give us a kiss.
Wicked Cultured: Enjoys wearing dapper clothing when blending in among humans, as well as attending classical music performances.
Woobie, Destroyer of Worlds: He's a genocidal ego-maniacal tyrant, but he's driven by loneliness and a desperate need to validate his own self-worth, and it's hard not to feel sorry for him.
Xanatos Speed Chess: He's not in full control of everything that happens in Thor, but he finds a way to makes things work to his advantage one way or the other.
Yandere: When Odin becomes ill just thinking about warring with the Frost Giants, Loki concludes that the quickest way to please his father is to blow up the Frost Giants' world.
In Thor, an indirect version—since only one of the characters is aware of the relation—takes place when Loki shoots Laufey with Gungnir while making it clear who he considers to be his true parent:
Loki: And your death came by the son of Odin.
In The Dark World, he furiously yells a variation of this when he and Frigga discuss Odin. Somewhat justified, as Loki had been disowned and would've been executed if it weren't for his mother's influence.
Lord of the Aesir and King of Asgard. After Thor starts a war with the Jötunns, he exiles him in hopes of teaching him humility. Upon a particularly strenuous conversation with Loki, his old body goes into the "Odinsleep." Loki promptly takes advantage of this and starts scheming.
A God I Am Not: When Loki asserts that the Asgardians are like Gods compared to Humans, Odin succinctly declares that they should not act Holier Than Thou in spite of their advantages as a species. However, this does not stop him from acting superior to Jane when she comes to the realm, probably because he feels that she's not good enough/too mortal for his son, more than anything else.
Broken Pedestal: To his youngest son Loki, who greatly loved him, looked up to him and wanted nothing more than his approval in Thor. The breaking part started once Loki found out Odin had lied to him his whole life about his origins and planned to use him as a tool. Odin's final rejection in the Bifröst put the final nail in the coffin.
Chewing the Scenery: Whenever Odin gets angry and raises his voice. Magnificent in a way that only Anthony Hopkins can deliver.
Determinator: Has been putting off the Odinsleep for quite a while. In the opening for Thor, he takes an ice mace from Laufey in the face and continues fighting anyway. He doesn't even stop to seek treatment for his eye until after the Frost Giants are driven back to Jötunheim.
Despair Event Horizon: Succumbs to it when Frigga is killed in The Dark World. He throws out all the virtues he instilled in Thor and only sees red. He even drives Heimdall to go against him!
Believed that Loki would be able to forge a lasting peace with the Frost Giants, despite the fact Laufey left him to die as baby.
Didnt see that Loki would be incredibly upset or jealous about not being Crown Prince. Even worse - he didn't make it clear Thor was the Crown Prince when they were young, dangling the throne in front of both of them, telling them "only one of you can inherit the throne, but you were both born to be kings." The director of The Dark World has commented on how Odin really shouldn't have done that.
The Good King: Taking care of his people is his number one priority and his anger at Thor is based on his fear that his son cares more for war then for them.
Gold and White Are Divine: As his image shows he wears various combinations of silver and gold and has white hair. Noteably, his sons each appropriate one of the two colors for their own outfits.
Loves both his sons, even if Loki is an adopted Frost Giant, a racial enemy, and gives Thor a much needed object-lesson to teach him the value of kindness and compassion. His main failure is being too prideful in his sons to teach them the lessons they needed to learn until it was too late, resulting in Thor becoming a boisterous warmonger and Loki becoming a repressed ball of jealousy. Only one of them gets better (since any opportunity to correct Loki's immaturity was missed when he fell into Odinsleep, leading his adopted son to run amok with power).
In The Dark World he reminds Loki that his birthright was "to die, as a child, on a frozen rock" and if he hadn't saved Loki that day then Loki wouldn't be alive to hate him in the present. How much of the punishment is from the "All Father" and how much is from "Loki's father" is ambigious in the film note The Dark World Prelude comics suggest that it's both of them . In any case he's given up hope that Loki would amount to anything more than a murderer.
Heavy Sleeper: Nothing can wake him from the Odinsleep once it begins, although he still sees and hears everything going on around him.
I Have No Son: After Loki murdered millions of innocent New Yorkers in The Avengers, Odin no longer considers him his son. In the Dark World Prelude comics, he underlines this by calling him Laufeyson to his face.
Jerkass Has a Point: Although he stepped off the Despair Event Horizon by that point and was ready to expend unit after unit to fight Malekith in Asgard, Odin did have a point about Thor's plot to bring Jane to Malekith in Svartalfheim if Thor can't destroy the Aether once it's extracted from Jane as that's precisely what happens.
Never My Fault: He doesn't take any responsibility for how his sons turned out. It doesn't dawn at him at all that Thor's war-mongering behavior is because of him, or that Loki's issues were due to nelegcting him as a child, which resulted in his madness.
He never told Loki of his true heritage because he felt it would cause him to feel like an outsider. Even when Loki didn't know the truth, he still felt overshadowed by Thor and Odin. Finding out just made things worse, much worse.
He went into Odin Sleep after banishing Thor, which put Loki on the throne.
Not So Different: From either of his sons. In Thor: The Dark World, he shows himself very much like Thor in the first film, with his bloodthirsty ways in the fight with the Dark Elves. Of course, he has better reason. He also shares Loki's attitudes about being superior to humans, though the latter comes with the caveat of the fact that he would first have encountered humanity in the early bronze age, through to the Viking Era, so it isn't exactly surprising. On the better traits, he shares Thor's courage, nobility and ability to lead, with Loki's intelligence and diplomatic skills, as well as, to some extent, magic (he shows signs of it in The Dark World when he examines Jane for the Aether.
Papa Wolf: Goes into Jötunheim, by himself, to rescue his sons.
Parental Neglect: Played with. He loves (or use to love) both his sons, but since Thor was the eldest and the heir to the throne, he gave him more attention than Loki to whom he was always somewhat distant. This had very tragic results.
Gives one to Thor around the beginning of the film, but it was meant to inspire some humility in him, and not just for the sake of being mean-spirited.
"You are a vain, greedy, cruel boy!"
"Through your arrogance and stupidity, you have opened these peaceful realms and innocent lives to the horror and desolation of war! You are unworthy of these realms! You're unworthy of your title! You are unworthy!...of the loved ones you have betrayed. I now take from you your power! In the name of my father and his father before, I, Odin Allfather, cast you out!"
Also gives a brief one to Loki before sending him to the dungeon in The Dark World.
"Do you not truly feel the gravity of your crimes? Wherever you go, there is war, ruin, and death."
"Your birthright, was to die, as a child, cast out onto a frozen rock. If I had not taken you then, you would not be here now to hate me."
Retired Badass: He led the charge back in the 10th century AD, but now he prefers the diplomatic approach.
In The Dark World he stops treating Loki like his son, and is openly disapproving of Thor's infatuation with Jane, comparing bringing Jane to Asgard to bringing a goat to a banquet (and says this to her face, no less). . Most likely, it was probably caused by the fact that his second son, who he does still love, went insane, slaughtering thousands (at a conservative estimate) of innocents, and the fact that his first son is in love with a mortal who will break his heart by dying a millennium or three before Thor starts even going grey.
He takes another level in the second half of the film due to grief and anger over Frigga's death and shouts We Have Reserves.
What Happened to the Mouse?: At the end of the second film, Loki has usurped the throne from Odin, whose fate is not revealed in the film.
Badass: Thor definitely didn't get it all from his father. She easily bests Malekith in combat, taking him on alone armed with nothing but a shortsword and sheer unadulterated skill. It's a shame he brought Kurse along.
Death by Adaptation: She didn't die (at least permanently) in the comics, but she's killed in The Dark World.
Violently Protective Girlfriend: She not only takes care of Odin in the Odinsleep, but guards him as well. She takes pride in this, as witnessed by her interaction with Odin while they prepare for Malekith's invasion:
True Companions: To say that they're Thor's dearest and most loyal friends is an understatement.
We Used to Be Friends: Even though they grew up together and loved each other like a family, all four of them now hold Loki in nothing but cold contempt and hatred after his actions in The Battle of Manhattan.
"I will die a warrior's death. Stories will be told of this day!"
Glory Seeker: As the quote above indicates, she was ready to go down fighting the Destroyer.
Green-Eyed Monster: Downplayed. While she may be jealous of Jane's relationship with Thor she accepts it and bears Jane no ill will for it. Even her actress said she's above all that, the most antagonistic Sif gets toward Jane is a glare because Jane's presence is threatening Asgard, not because she's dating Thor.
Hopeless With Tech: Averted, surprisingly. Coulson tries to explain to Sif how to use The Bus' touch screen, but she proves perfectly familiar with the interface from her time in non-magical alien societies. She even calls the system "antiquated."
Hot-Blooded: She can be quite impulsive when she gets frustrated.
Secret Keeper: Her guest spot on Agents of S.H.I.E.L.D. makes her the only character tied strongly to a particular film series rather than the MCU as a whole to know that Coulson is still alive. He asks her to let him tell Thor himself.
Implied as of Thor with Sif to Thor. (She's Thor's main love interest in the comics and his wife in the myth.) According to interviews, this was more explicit in scenes that were later cut. This was made more explicit in The Dark World, in that she tries to reach out and comfort Thor's increasing broodiness, and yet gets the courteous-yet-curt reply of:
Demoted to Extra: Makes a brief appearance early in The Dark World, having remained in his home realm to help rebuild it after the Marauders' attack; has another appearance, no more than a reaction shot, during the portal-hopping battle of the finale.
The Quiet One: He rarely speaks, so when he does, the others listen.
Race Lift: Hogun in the comics is vaguely Mongolian-looking and based on Charles Bronson. Here, he's Japanese-looking. He seems to have grown an impressive beard during Thor: The Dark World, which harkens back to Asano's portrayal of Genghis Khan in the film Mongol.
Not So Stoic: Even he gives a big grin when they find Thor on "Midgard".
The gatekeeper of Asgard and guardian of the Bifröst. His eyes see all that takes place in the Nine Realms, and his omniscience is thought to be even greater than Odin's. The most loyal and possibly the mightiest warrior of Asgard.
Badass: Very. Able to take down a camouflaging Dark Elf spaceship singlehandedly with only two daggers, he's powerful enough to match Odin himself - but Odin does not fear him because Heimdall is absolutely loyal.
Badass Baritone: When you hear his deep and powerful voice, it becomes clear why Idris Elba was chosen for this role.
Badass Beard: Sports a pretty good beard, though it's hidden mostly by his helmet.
Black Dude Dies First: Subverted. While he's the first person Loki attacks in his Evil Plan, he breaks out of it and brings Thor back and the final scene of the movie is him standing at his post like always.
In The Dark World, Thor approached him to help him and Loki escape to Svartalfheim and take the battle to Malekith. He mentions what they plan to do is treason, and yet goes along with it, taking the initiative to distract Odin:
Odin: You have called me for an urgent matter, Heimdall, what is it? Heimdall: Treason, my lord. Odin: Whose? Heimdall: Mine.
The Omniscient: Downplayed Trope. He can see and hear anything he wishes in the Nine Realms with perfect clarity, but he has to be looking for it. There are also a number of things he can't see even when he is looking, which always catches his attention. Dark elf cloaking tech, for example, fools his sight perfectly but he can still hear their engines.
Race Lift: He's white in the comics. This was a point of contention for some fans, applied rather inconsistently (see Hogun). The actor and producers called out the fans on how ridiculous it is to say that a human actor playing a comic book character based on a mythological concept doesn't look like how the fans wanted.
The Stoic: One imagines standing as the eternal guardian of the gateway to all the nine realms either requires or breeds a certain emotional detachment. He's friendlier in The Dark World, at least to Thor.
The Worf Effect: A variation in The Dark World: You know the Dark Elves will be a threat when even Heimdall can't sense their presence. This may be related to the possibility that the Dark Elves predate him.
The Brute: Temporarily a non-sentient one to Loki in Thor once he takes the throne.
Fighting a Shadow: Killing the Destroyer doesn't harm its user, seeing as it is controlled by an extension of the user's mind. In a sense, the fight with it could be considered the first battle between the Asgardians and Loki.
Power Glows: The opening in the face glows when it is about to fire.
The Voiceless: Justified, in that it's not alive, and is more of a weapon than a character.
What Happened to the Mouse?: In the film it isn't shown what happened to it after it was destroyed. The tie-in comic Fury's Big Week shows that S.H.I.E.L.D. took custody of it, and are now trying to reverse-engineer it. As shown in The Avengers, they are successful.
An astrophysicist who finds out that a wormhole she's been observing is really the Bifröst Bridge. Helps out Thor, and eventually falls in love with him.
Adorkable: She's usually a level-headed scientist, but anytime Thor turns on the charm, she turns into a giggling schoolgirl. She's also exhilarated in The Dark World whenever she encounters Asgardian technology.
Badass Bookworm: She relies on her intellect and her inventions when taking part in the action.
Badass Normal: In a world of gods, aliens, and superheroes, Jane is just a normal person with no enchantments or physical enhancements. Yet she uses her intelligence to solve problems and remains an active part of the conflicts.
Beware the Nice Ones: She's usually easy-going, but she will throw a punch at people who get her mad.
Clarke's Third Law: She quotes it to strengthen her argument about her research, which is admittedly going into less grounded territory.
Deadpan Snarker: Not very often, but by The Dark World, she reacts like this at times.
Darcy: It's okay, we're Americans! Jane: Is that supposed to make them like us?
Determinator: It's clear from her very first scene that she's ready to do anything for her research, namely driving directly into a tornado.
Did You Just Flip Off Cthulhu?: She slapped Thor twice, and Loki later. Granted, Thor probably felt nothing, but she still physically assaulted a pair of gods.
Dude, Where's My Respect?: Regarding Jane's motivation in Thor, Natalie Portman explained that her theories about connecting dimensions have her being looked down by the scientific community. If the post-credits scene is anything to go by, she finally got it.
Natalie Portman: Everyone thinks she’s on the fringe of science and that she’s this kook, so this is her opportunity to prove herself.
Gadgeteer Genius: In Thor, she mentions that she built most of her equipment herself.
Girliness Upgrade: Downplayed and lampshaded early on in The Dark World, complete with her first outfit of the picture incorporating Proper Tights with a Skirt. Later scenes show her wearing something like "Asgardian noblewoman casual wear".
Natalie Portman:I was like, ‘What a great opportunity, in a very big movie that is going to be seen by a lot of people, to have a woman as a scientist.’ She’s a very serious scientist. Because in the comic she’s a nurse and now they made her an astrophysicist. Really, I know it sounds silly, but it is those little things that makes girls think it’s possible. It doesn’t give them a [role] model of ‘Oh, I just have to dress cute in movies.’”
Only Sane Man: She easily buys into Thor's story, but does so in a scientific way. Her photographs show that Thor was in the Einstein-Rosen bridge, and she points out that it has to lead to somewhere.
Put on a Bus: SHIELD put her on one to safety before the events of The Avengers; see Real Life Writes the Plot. Then The Bus Came Back and she appears in The Dark World where she's quite miffed that Thor didn't come to see her during his last visit to Earth, and she had to learn about it from the news.
An astrophysicist and college professor working with Jane Foster on studying wormhole anomalies. He suspects Thor of being crazy because he recognize all of his stories from childhood, but in the end helped him out - specifically creating a fake identity for him as "Donald Blake." Was brainwashed by Loki in the Avengers, and is shown to be still affected by the experience in The Dark World.
Agent Scully: Never believed any of the supernatural aspects of Thor because they sounded too much like the stories he heard as a child. Repeatedly points this out to Jane.
Big Damn Heroes: At the end of Dark World, saves Thor and Jane from being crushed by Malekith's ship by using the tech he invented to open a portal above them. As an added bonus, he ends up teleporting it right on top of Malekith, finishing him off for good. Not bad for a guy who had to be busted out of an insane asylum earlier that day.
Brainwashed and Crazy: Loki somehow influences his actions in the stinger of Thor, then gives him the full Chitauri scepter treatment in The Avengers.
For Science!: Gains this sort of glee after Loki mind-controls him.
Go Mad from the Revelation: Becomes unhinged in The Dark World after his brainwashing. On a more mundane level, the undoing of it (getting thrown 30 feet by a small explosion and hitting his head really hard) on a man likely in his sixties probably helped make it worse.
Hourglass Plot: In both The Avengers and Thor : The Dark World, his experience with cosmic happenings has taken him far away from his rationalist origins.
Irony: Started as a rationalist, down-to-earth scientist skeptical about mythical resonances to cosmic events, then he eventually becomes a Cloud Cuckoo Lander with his reputation in tatters. He has a "World of Cardboard" Speech about it in Thor : The Dark World after which he becomes functional again.
Fun Personified: Most of her scenes have her nonchanantly doing or saying something funny.
Genius Ditz: Doesn't get most of what Jane and Eric talk about, but she's the one to point out that primitive humans could have mistaken people like Thor for gods. She's also the one who spots the Thor-shaped silhouette in Jane's pictures of the Bifröst opening.
Malaproper: She's completely unable to pronounce "Mjölnir."
Moment Killer: She has a habit of interrupting Jane whenever she's trying to have a romantic moment. She is perfectly aware of it and finds it quite funny.
Not That Kind of Doctor: Political science, not astrophysics. (She became Jane's assistant because she was the only one who applied for the job.)
Odd Friendship: With Jane the calmer and yet also more hotblooded astrophysist
The King of Jötunheim and a Frost Giant. Over 1,200 years ago, Laufey invaded Earth (Midgard) in an attempt to conquer it, but Odin and the Gods came to Earth's aid and pushed them back to Jötunheim and defeated them, and took the Casket of Ancient Winters, a powerful artifact, from them. Since then, Laufey desires peace first, but if possible, to get the Casket back.
Disc One Final Boss: While Loki is revealed to be the one who allowed Frost Giants into Asgard, and makes a deal to allow them inside in force, King Laufey is assumed (at least in-universe) to be the primary antagonist of Thor.
Dropped a Bridge on Him: For such a mighty warrior, all it takes is two shots from Loki to disintegrate him. Though those two shots came from Odin All-Father's staff, one of the most powerful weapons in Asgard's general vicinity.
Gender Flip: In Norse Mythology, Laufey is Loki's mother, and a Frost Giant called Farbuti is his father, but in the comics and the film, Laufey is the father and a unidentified female (possibly Aesir) for the mother.
Parental Abandonment: To infant Loki and later tells Loki that Odin should have left him to die instead of saving and raising him as his own son.
Pragmatic Villainy: Laufey is evil, but he's not stupid. He knows that Odin's a dangerous enemy, and wants to make sure that the Asgardians fire the first shot so he can have the moral high ground when he starts the war. Loki cleverly plays this trait against him by setting him up. He allows Laufey and a few Jötunns into Asgard to assassinate Odin (causing Laufey to believe he has an ally within Asgard) while he sleeps, but only so Loki can then turn the tables on Laufey, kill him, and give himself the moral high ground in order to start a war with Jötunheim.
Reasonable Authority Figure: He was prepared to let Thor and his buddies go after they invaded his nation and violated the truce, because he knows that Thor is an immature boy that doesn't understand war.
Adaptational Badass: In the comics he's not a great fighter, and is much more prone to use his shapeshifting skills and various schemes than to face his opponents head-on. In the movie, his characterization is changed, probably so that he would make a more impressive Big Bad (in the comics he's merely The Dragon). Another possible reason for the change is that the comic book version of Malekith, whose favourite tactic is to deceive his enemies by pretending to be someone else, would've been too close to the movie Loki.
Authority Equals Asskicking: Downplayed. He's certainly a great fighter and more badass than in the comics, but Kurse is stronger than him and at one point Frigga gives him a serious fight. Played straight after he gets the Aether.
An Arm and a Leg: Gets both of his arms cut off by Thor in their final battle, though the Aether has started to reform his arms.
Badass: He's The Leader of the Dark Elves and quite skilled, even before he gets powered up by the Aether.
Dark Is Evil: He and his race were born in primordial darkness, and they despise the universe of light it became.
Death by Looking Up: Just had enough time to see his mothership crash upon him after being teleported back to his homeworld.
Dirty Coward: Threw his entire invasion fleet under the bus by depowering his ships to crush Asgard's forces when he lost the Aether during their first skirmish and to flee the battle, killing anyone who was on board at the time. He even has the gall to claim Asgard forced his hand and they will be the ones to pay for his own cowardice.
Generic Doomsday Villain: He's out to destroy the universe and return everything to darkness, but his motives for doing so are relatively unexplored. Apparently, they had intended to flesh out Malekith's character through additional scenes (according to Eccleston), but it was excised from the film proper (might show up as deleted footage or some other supplementary material in the home release).
Good Scars, Evil Scars: It should be obvious what kind he has but just in case half his face burned by Thor's lightning because he invaded Asgard and killed its queen.
Irony: At the end of the first war with Asgard, he dropped his fleet onto the battling armies, slaughtering both sides to cover his escape. Eric Selvig warps his collapsing mothership right on top of him, killing him after he was soundly beaten by Thor.
Karmic Death: He sacrificed most of his people by making their ships drop on them and his enemies. He's ultimately defeated by his own ship dropping on top of him.
Make My Monster Grow: During the climax of the Convergence, when Malekith starts releasing the energies of the Aether, he grows to about three times Thor's height. Though when Thor delivers the final blow on him with Mjölnir, he immediately reverts back to his normal height.
Royals Who Actually Do Something: King of his people and the Big Bad of The Dark World. It's implied in interviews that in regards to his plan for destroying the Universe, his Elves are with him all the way.
Time Abyss: He's older than Odin, and possibly older than the universe itself.
Two-Faced: Due to half of his face being burned off thanks to lightning from Mjölnir.
We Have Reserves: To escape in the first act, set millennia in the past, he sacrifices reserves of his men, and then escapes with his lieutenant and a skeleton crew of elves.
Malekith's lieutenant who is one of the few Dark Elves to survive the war against Odin's father Bor, and continues to serve Malekith. Malekith allows him to use an ancient Dangerous Forbidden Technique, transforming him into the nigh-unbeatable Kurse.
Adaptation Distillation: In the Thor comics, Algrim/Kurse was a minor villain, whose only appearance had been in the same issue where he died, until an omnipotent Cosmic Entity revived him and made him massively powerful as part of a crossover that had nothing to do with the main plot of The Mighty Thor. For understandable reasons, the movie gives him a rather different backstory.
Adaptational Villainy: In the comics, Algrim/Kurse does work for Malekith for a time, but Malekith betrays him and Algrim—a noble soul—swears loyalty to Thor and Asgard, in fact being the one to kill Malekith himself. In The Dark World, Malekith does sacrifice his own people but doesn't betray Algrim personally. Algrim has Undying Loyalty towards his master and becomes Kurse as a result.
Badass: He was already a capable warrior, but when he becomes Kurse, he easily kills scores of Asgardians, including Frigga, and Thor is no match for him in pure physical combat. Even Mjölnir causes little harm.
Black Best Friend: An evil version to Malekith; a black Dark Elf that appears to be his friend in aiddition to lieutenant.
Body Horror: What happens to him (and all other Dark Elves) when transforming into Kurse; as described by the art book, his armor is basically grafted onto his body, with no sign of it being reversible.
The Brute: Becomes this to the Dark Elves after becoming Kurse because he becomes much stronger at the expense of high functions.
Eye Scream: His eyes are visibly ripped from their sockets by the black hole grenade that Loki set off.
Hero Killer: As Kurse, he's both incredibly strong and not without a fiendish intelligence. He first kills his share of Einherjars, then is the one to stab Frigga to death, and during his battle with Thor and Loki, he appears to kill the latter.
Hoist by His Own Petard: Loki manages to defeat him by activating the black hole grenade on his belt that the Dark Elves earlier used to great effect against the Asgardians.
The Juggernaut: As Kurse, he shrugs off everything that's thrown at him. It takes a black hole grenade to finally get rid of him.
Mighty Glacier: Slower than the Hulk, or Thor, but much stronger and tougher.
Neck Lift: A signature move once he becomes Kursed.
Nigh-Invulnerability: Kurse is only defeated by being sucked into a miniature black hole. Nothing else so much as puts a dent in him.
Non-Standard Character Design: All the other Kursed have their doll masks become their faces in the prologue. Since Algrim was disguised as a Marauder, his Kurse form has a more expressive and demonic visage.
Painful Transformation: Algrim's transformation into Kurse has him burning from the inside out and thrashing wildly in his prison cell.
Scary Black Man: More so as Kurse because he's basically a demon, but also less so because his armor has been grafted on and thus conceals his skin.
Super Strength: As Kurse, he's more than a match for Thor, being able to beat up the thunder god in single combat.
Time Abyss: He's older than Odin, and possibly older than the universe itself.
Touch of Death: As Kurse, he can fry people by grabbing them with a choke-hold.
Trojan Prisoner: He's sent into Asgard disguised as a marauder prisoner just after being given the Kurse stone, knowing that when the transformation kicks in, he can break out with ease.
Undying Loyalty/Villainous Valor: Seems to be a racial trait. They might be evil, but Algrim and the Dark Elves in general are also unyieldingly loyal to Malekith, even after he sacrifices a whole fleet to escape. Taking up the "Kurse" is very much this: a Dark Elf will willingly submit to the painful and eventually deadly transformation into a giant monster, and fight for their people until it kills them.
