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 5,000 years. This probably includes Frost Giants as well, considering that King Laufey looks exactly the same as he does 1,029 year after the battle of 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 Bifrost enables them to be anywhere at a moment's notice, fear of them is what keeps punks like the Jotuns, Trolls, Badoon and Marauders in line. Which is why when the Bifrost goes down all the evil races come out of the bushes and start wreaking havoc.
Ye Olde Butchered English: Toned down considerably from the source material but still present. Asgardians, futuristic technology notwithstanding, speak with extreme formality and correct grammar that would not be out of place in Victorian London. Not once in their onscreen appearances are they given to contractions note (e.g. "I am" instead of "I'm", "It is" instead of "It's", "He is" instead of "He's," etc.), superfluous analogies and idioms, or any modern-slang in their vocabulary and syntax.
With the exception of Loki, who is prone to quite vicious and vulgar slang (i.e. "quim", an archaic form of "cunt") when he is annoyed/enraged. He also uses exclamations like "Ta-da!".
The Norse God of Thunder, son of Odin, brother of Loki, and the heir to the Asgardian throne. He carries "Mjolnir", 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: Painfully sweet, polite, and gallant to women, especially Jane.
The Atoner: While not a straight villain-to-hero example, his film was his evolution from a spoiled, vain boy to a wise man through atonement and humility.
Badass: Out of his group of warriors, he's the best. Even more so when you consider that he wasn't at his best in The Avengers (see Worf Had The Flu), yet still managed to go toe to toe with the Hulk.
Badass Baritone: Chris makes Thor sound like the hero of an ancient epic; appropriate no?
Badass Beard: His is much trimmer than his father's, though it still adds to his manliness.
Badass Cape: He wears one as part of his 'super god warrior' armor. He loses it when de-powered.
Bash Brothers: Captain America, a man of nobility, kindness and courage, is a human that Thor has come to regard as an equal; most tellingly when he offers his hand to help him up during the battle of Manhattan.
In The Dark World he is literally this with his brother, Loki, during the penultimate act.
For the love of Odin, don't tell him to put his hammer down. As Cap found out, he'll put it down...on your head.
Pretty much any insult will push Thor to a towering rage, at least before he learns humility in his banishment to Earth. Although he does still go nuts against Tony Stark (after the latter has turned and started to walk away) for calling him a "tourist."
"He's constantly having to battle for the greater good and what he should do, versus it's his little brother there."
Subverted in The Dark World, where he tells Loki he no longer considers him his brother. Actually double subverted: he is 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.
The Big Guy: Shares the role with Hulk in The Avengers. Lampshaded by his page quote here. A Type 2.
Blood Knight: At the start anyway he 'cultivated 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 hinted several times that his understanding of Asgardian technology is limited mostly to the fact that "It works", and he seems genuinely impressed that Jane, Selvig, and the other humans appear to understand the underlying principles behind it better than he does.
Boisterous Bruiser: He starts off a battle-seeking brat, but wises up and settles on this.
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 hotheaded 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 Jotunheim 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 likeable, fun guy who will smash your face in with a hammer if you threaten Earth or Asgard.
Hair-Trigger Temper: His former fatal flaw, which would have doomed Asgard if he was crowned without having it cured.
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. And of course, he has a rather epic 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 3 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 on landing in Midgard), the God of Thunder is taken down by... a taser.
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.
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.
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-shotting frost monsters and (though it isn't obvious at first) easily overpowering Tony's armour, 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 SHIELD, 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.
One God Army: He slaughtered dozens of frost giants singlehandedly 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.
Physical God: Literally, which is part of why it's very hard to hurt him seriously when he's at full strength.
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.
Strong as They Need to Be: Used for comedic purposes during the time he's depowered. When it's funny, he can be taken out easily (by Darcy's taser, Jane ramming him with a van, getting an injection), but he's also shown curbstomping scores of highly trained SHIELD personnel who are in peak physical condition. It's also justified by his Heart Of Gold; he won't Get Dangerous unless he believes that they won't be killed by it or they deserve to die.
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 Mjolnir, 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: (about Thor and Sif) 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...
Warrior Prince: Any prince of the Asgardians is this because they are a warrior culture.
"Well Done, Son" Guy: Sets up war between Asgard and Jotunheim by trying to live up to his father's legacy. He's almost crying when Odin strips him of his armor, weapon, and title.
Odin: You are unworthy... of the loved ones you have betrayed.
We Used to Be Friends: By the time of The Avengers, any friendship he had with his brother, Loki, is gone. In their first encounter back together, he tries to make Loki remember, but he's too far gone.
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 Jotunheim 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 is often depicted as being hideous.
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.
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: 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.
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: He does morally questionable things to protect Asgard and prove himself worthy to his father in Thor. In The Avengers, he is a straight villain. And, interestingly enough, he's a mix between this and Nominal Hero in The Dark World.
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.
Badass Bookworm: Since he studies magic, he's the Asgardian equivalent of a 'nerd'.
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.
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 armour 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.
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.
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."
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 its 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.
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 pretty much 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.
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.
Green-Eyed Monster: While it's not his motivation, Loki is consumed by his envy of Thor and has a heck of a time hiding it in the first act of Thor.
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.
I Am Who?: He's actually a Frost Giant and Laufey's son, rescued from Jotunheim when Odin last defeated the Frost Giants. He doesn't take The Reveal well.
An Ice Person: Starts using the Ice Casket of the Frost Giants in Thorafter he discovers that he is a Frost Giant.
I Did What I Had to Do: Uses this when explaining to Odin why he attacked Earth in the Thor: The Dark World Prelude.
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.
Insane Troll Logic: Loki's motivation in The Avengers follows as this: He wants to conquer Earth, because if humans are too busy worshipping 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.
Irony: The actions motivated by his desire to prove himself to his adopted father wind up getting him disowned outright and thrown in the dungeons. Oops.
It's All About Me: He's willing to destroy an entire planet just to work out his family issues.
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 also 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 much more people than him to preserve peace in the Nine Realms. Considering Bor all but exterminated the Dark Elves, he does have 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 Jotuns, 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 — naturally, Cap does not.
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.
Kung-Fu Wizard/Magic Knight: Along with his cunning and sorcery, Loki is also a fairly formidable physical fighter who uses capoeira, knives, and a staff to hold his own in battle against heroes such as Thor.
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."
The Man Makes the Weapon: 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.
It's a tendency he seems to leave behind in The Dark World, in which he's never armed with more than a dagger and makes good use of it, 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.
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 Guy: 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 or others in combat, preferring to compensate with his intelligence and cunning. As such, he tends to use trickery to avoid direct conflict. Subverted in The Avengers, where he is willing to dirty his hands against SHIELD agents that are no threat to him and proves Captain America's superior during their short battle.
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. Subverted when he doesn't, though he does trick Thor into thinking he died while he goes into hiding via shapeshifting.
In fact, he and Thor use the fact that everyone (including the viewers) is expecting a betrayal from Loki to their advantage when Loki almost literally stabs Thor in the back then cuts off his hand when he tries to summon Mjolnir and proceeds to hand Jane over to the Dark Elves. The second that Malekith completes the part of his own plan that he needed Jane for, Thor and Loki reveal that Loki's "betrayal" was actually just another one of his elaborate illusions used as part of the brothers' Batman-Gambit to trick the Dark Elves into doing exactly what Thor wanted them to do.
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.
He later usurps Odin's throne as payback for being disowned and for almost receiving the death sentence.
Royal Brat: Like Thor, Loki has overtones of this. He has no problem getting guards and Jotuns 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.
In the first film, he wields Gungnir, the symbol of kingship in Asgard, when he becomes regent.
In The Dark World, Gungnir is once again in his possession in the final scene.
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 most scariest expression he's got.
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.
Took a Level in Badass: Going through a wormhole has given 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 is 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.
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 Jotunheim 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 Jotnar.
Starting around the time he discovers he is 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.
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.
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 Jotuns, 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.
Eye Scream: Loses his right eye to Laufey in Thor's opening.
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.
Good Parents: 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).
Subverted in The Dark World, where he wants nothing to do with Loki after The Avengers. He would've killed Loki if it weren't for Frigga.
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.
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.
Took a Level in Jerkass: In The Dark World, he becomes more selfish and frustrated towards his citizens, 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). He's even more irate in the second half due to the death of Frigga, but even before then he's showing a much less pleasant side of himself in comparison to the first movie.
Truth in Television: In Norse mythology, Odin is capricious, bloodthirsty, quick to anger and extremely arrogant; much closer to his depiction in The Dark World than in the first film. In fact, Odin is the Norse patron god of war while Thor is the Norse patron god of justice.
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.
Reasonably Protective Wife: 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 he murdered millions of innocents in The Battle of Manhattan.
"I will die a warrior's death. Stories will be told of this day!"
Tomboyish Ponytail: Wears one when going into battle. She seems to have dropped the habit during Thor: The Dark World.
Unlucky Childhood Friend: 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 seems to be trying 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 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. 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.
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.
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: To some extent. He can see and hear anything he wishes in any realm he wishes with perfect clarity, so long as he has some idea of what to focus on. It's of interest to him when he finds himself unable to see an event taking place.
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. Is currently a S.H.I.E.L.D. scientist working under Coulson trying to find a way to reopen the Bifröst.
Adorkable: She's usually a level-headed scientist, but anytime Thor turns on the charm, she turns into a giggling schoolgirl.
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.
Living MacGuffin: She becomes one for a while in The Dark World after inadvertently becoming the host of the Aether.
Muggles Do It Better: In The Dark World, the villains are able to bypass the defenses of the Asguardians, yet they are no match for Jane's technology.
Neutral Female: In The Dark World, this is averted. The sensors she and Selvig build, combined with the Convergence, come in handy to fight the Elves and save people's lives.
Only Sane Woman: 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.
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.
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.
The King of Jotunheim 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 Jotunheim 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.
Abusive Parents: Left his weak and tiny (for a Frost Giant) infant son out in the cold to die. Said son, Loki, was then found by Odin and raised as his own.
Karmic Death: Said son later kills him in order to gain the approval of his foster father.
Affably Evil: Almost always calm, even-toned and polite when talking to the Asgardians.
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 Jotuns 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 Jotunheim.
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.
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: The Dark Elves are significantly unhappy with the brightly lit place the Universe has become, and intend to turn it back to darkness. Scenes detailing much of this were cut from the movie.
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.
Royals Who Actually Do Something: King of his people and the Big Bad of The Dark World. It's implied in interviews that his plan for destroying the Universe... yeah his Elves are pretty much with him all the way.
Time Abyss: He is 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 Mjolnir.
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 Mjolnir causes little harm.
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 pretty much 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: Practically 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.
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 is 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 dicks but him 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.
