A god of wisdom, war (emphasis on strategy), poetry, magic, frenzy and death who is the head of the Aesir. Modern interpretation of him varies. Some see him as a noble god and respect him for the theme of self-sacrifice and view his ruthless actions as necessary for preventing Ragnarok. Others see this as something of a Misaimed Fandom. They see him as being quite like Zeus—a philanderer and major-league jerk. Also, Wednesday is named after him ("Wodin's day", Wodin being one of his many names).
Everybody Hates Hades: Inverted by the Norse, if you believe the theory that Odin and the Valkries were identified with an older German death god who was even less fondly thought of before the Norsemen took a liking to them.
Eye Scream: Self-inflicted to be used as toll for a drink from the Well of Knowledge.
Jerk with a Heart of Gold: Odin can come off as a real jerk at times, but would often wander the earth testing mortals punishing and rewarding them.
Karma Houdini: Averted unlike many gods. Whatever crimes Odin may have committed he is destined to die at Ragnarok. Some people perceive this as punishment for a betrayal of Loki or his treachery in general. Another story has Odin being banished from Asgard and replaced as king for a period of ten years as punishment for the rape of Rindr which he undertook to father Vali. Note that this is something that could have happened in the Norse society which was proto-democratic. If a king was disliked by the people, they had the right to get rid of him.
Nice Hat: When wandering around in human guise, he wore a dang cool one.
Ravens and Crows: Had a pair of ravens that would circle the world every day and whisper in his ear the secrets they found at the end of the day. Evidently they weren't perfect since Odin is portrayed as far from omniscient even with them and the ability to view any place in the nine worlds. He still gets tricked a few times.
Wholesome Cross Dresser: Historia Langobardorum shows that she had much to teach Odin when it came to which tribes he should be favoring, which she does by having a bunch of women disguise themselves with beards and present themselves to her husband.
Your Cheating Heart: All the Norse gods were jerk asses in Gesta Danorum but it particularly stands out with ones like Frigg, as not being guilty of infidelity was an important plot point on a couple of occasions.
Please note that Gesta Danorum is probably the most biased source of Norse Mythology there is.
Odin's son, who developed over time into the Purity Sue of the pantheon. He was immune to damage from anything except mistletoe, and Loki killed him by tricking his blind brother Hod into throwing a magic spear made of it at him.
Achilles' Heel / Weaksauce Weakness: To mistletoe note However, it is belived originally he was killed by a sword, the "mistletoe-arrow" only coming in the version recorded by Snorri Sturluson because of other sources telling of the magic sword "mistletoe". The confusion may have risen from that Snorri took the word for it and thought Baldr was killed by an actuall mistletoe
Back from the Dead: Some texts describe him as returning from Hel after Ragnarök has taken place, probably another sign of Christian influence on the character.
A thunder god and the favorite god of the average Norse farmer (Odin was only really liked by royalty and berserkers). Carries the title "Friend of the humans" (or, possibly, "Man's Best Friend") and would fight giants and various demoic threats to the gods and mankind. He was also considered the protector of slaves. Also has Thursday named after him (literally "Thor's Day").
Awesome McCoolname: Well, to start with Thor means thunder. But also the literal translation of Mjolnir is crusher. Yes, apparantly Thor follows the same naming conventions as macho men with their dogs.
Protectorate: He is the Friend of Humans and Protector Of Midgard, titles he received for his role in defending Midgard, human world, from giants. He's also the god of order, in direct contrast to Odin.
Space Is an Ocean: While most would use such things as Slepnir and Bifröst to pass through the nine worlds Thor preferred to wade his way across. He did have a chariot with two goats for transporting other people though. This is used to describe why rainbows follow thunderstorms.
Would Hit a Girl: Althrough a much more sympathic than Odin and a heroic defender of the weak, he would no back away from attacking a giantess or a female monster despite that the laws of the Norsemen (endorsed by Odin) considered the harming and killing of women monstrous.
Wolverine Publicity: If there's a heroic Norse god in modern media, it's Thor. Appropriately, Marvel Comics is the most obvious example.
A noble war (emphasis on protection) god, confused with the Roman Mars, Tuesday is named after him (one of his names is Tiw so it is "Tyr's day"). He is attributed as a god of justice (due to historical evidence suggesting he was called upon in courts), and he was the only god who did not fear Fenrir.
Demoted to Extra: Tyr only appears in three tales, and is only important in one of them. Considering he was a god of soldiers and the poems and sagas where written for the ruling classes who favored Odin this is not suprising.
Some experts believe that while both Týr and Odin have always been connected to war, Týr was more popular until the violent Migration Period when the germanic tribes favoured a god that might bring them victory and turned to the other candidate Odin.
Týr is belived by some experts to have been the original king of the gods but Odin's popularity supplanted him. This is based on mainly linguistic and some ethnologic evidence which are very much in the area of speculation. Týr's name is considered to share an origin with Jupiter, Zeus and a few other heads of pantheons making him the Norse equivalent of the Indo-European sky deity. On the other hand, Týr shares few things in common with these sky gods and the only possible connection between them is that his sacrifice of his hand to bind Fenrir is this connection; Fenrir being prophesised to eat the sun. The loss of the hand symbolises the moon. His other hand symbolises the sun. The problem with this is that the germanic tribes considered the sun to be a female deity (see Sunna) driving the sun in a chariot (the later part having evidence dating to the bronze age). Thor on the other hand shares a ton of mythological similarites with other sky gods all over Europe, Egypt and India. This is all very much YMMW-items.
War God: Can be seen as one of these. Though he was usually treated as the god of single combat and soliders instead.
Well, almost every Norse god was a War God, so they had to specialize.
Vidarr is the son of Odin by Gríđr, a Jötunn who aided the gods against Loki. During the events of the Ragnarök, while Thor fights Jörmungandr, Týr fights Garm, and Freyr fights Surtr, it falls to Víđarr to fight Fenrir. Rising to the challenge, he not only avenges his father, but survives both the battle and the Ragnarök. This earns him a reputation as a god of vengeance.
Bad Ass: He bends Fenrir's jaw open with his foot and his left hand. Note that at this point Fenrirs is said to have grown so large his upperjaw hits the freaking sky.
Improbable Weapon User: Uses his good leather boots to kick off Fenrir's top jaw, through the earlier version simply has him use his foot to bend Fenrir's jaw open before shoving Odin's spear down is throat and into his heart.
Odd Job Gods: God of space (in the sense of distance), silence, vengeance, and footwear.
One-Man Army: Some versions have it that he comes out the Ragnarök completely unscathed.
A son of Odin and the giantess Rindr, Váli was conceived specifically to avenge Baldr's death. He does this when he's less than a day old by killing Höđr and later helps the other Ćsir capture Loki. Like his brother Víđarr, he ultimately survives Ragnarök.
Mostly a love goddess and fertility goddess, but also is connected to bloodthirst, as Odin made her the commander of Valkyries and the goddess of magic and witches. Along with Freyr, her twin brother, she is a fertility goddess. Also the patron of warrioresses and witches. Her name is the origin for the word for "lady" in several Germanic languages. In Scandinavia, Friday is named after her (Fredag)
Freya's brother; they were both part of the Vanir, the other group of gods opposing the Aesir, until they ended up being hostages as part of a truce alongside their father Njord. A god of fertility and sex, generally more benevolent than his sister, and ultimately dies in Ragnarok as he gave up his magic sword for the love of a giantess. His name means "lord".
Alternate Mythology Equivalent: To Apollo; both are sun related gods associated with sexuality, and are not the only light related deities in their pantheon (the situation of replacement in the written myths is actually inverse: Apollo replaced Helios as the sun god, while Baldr replaced Freyr as a light god).
Bi the Way: A common interpretation of his character. Not really surprising considering he was a god of sexuality.
Chekhov's Missing Sword: He give his sword to Skirnir so his shield man could help him to win Gerd's heart. It isn't until Ragnarok that this event has a huge impact - Freyr fails to stop Surt since he is without weapon, allowing Surt to burn the world.
But not before partly blinding Surt with a deer-antler.
Canon Immigrant: Some have theorized that Bragi the god of poetry is a deified version of the real life bard Bragi Boddason, though this is by no means certain.
Bragi's wife and the keeper of the golden apples that the gods use to maintain their immortality. The Ćsir's only clear agriculture deity, through Thor and Siv/Sif are suggested to have been associated with it as well.
Fountain of Youth: The Norse gods are somewhat unique in that they are not innately immortal (as also demonstrated by Thor's wrestling match with the personification of old age) but need to eat Iđunn's apples to stay young.
A giantess who is counted among the Ćsir due to her marriage to Njörđr. She was allowed to choose a husband from the Ćsir, but was only allowed to see their feet, resulting in her choosing Njörđr. Godess of hunting, winter and sking.
Avenging the Villain: She originally came to the Ćsir seeking revenge for her father, Ţjassi. Considering that he kidnapped Iđunn and tried to deprive the gods of their immortality, it's surprising that the gods treated her as well as they did.
You Killed My Father: When Loki has chained for the killing of Balder, Skađi took the opportunity and placed a dead snake above Loki that dropped poison in his eyes.
The Watchman of the Aesir, permanently guarding the Bifrost Bridge against any threat - a task made easier by the fact that he can see and hear everything that happens in the world, and never needs to sleep. Left his post once to outdo Loki in retrieving Freyja's necklace from some giants, and then again for their final (and mutually fatal) battle. Heimdall is said to have sired the human classes and passed on the secret of the runes to them.
Has Nine Mommies: Has an unusual Origin Story, in some versions just appearing fully formed from the sea but in others being given birth to by each of the sea god's daughters, of which there were nine (one for each wave in a cycle).
Odin's brothers. They took part in Ymir's murder and the creation of humanity and Midgard, but are otherwise rarely mentioned.
Bait-and-Switch Tyrant: Ynglinga Saga states that after Odin had been gone for an exceptionally long time they decide he must be dead, and they were the default rulers of Asgard entitled share Frigg between them. It was not as bad as feared, neither wanted to have relations with their brother's wife, they just want to rule as equals beside her and immediately step down when Odin returns. Loki twists the story to Frigg throwing herself on Odin's brothers while he was away but he is dismissed.
Another one of Odin's brothers, who according to the Völuspá assisted him in the creation of humanity along with Lóđr. He is mentioned as having been sent to the Vanir as a hostage at the end of the Ćsir-Vanir war along with Mímir. Judging by one of the last stanzas of Völuspá, he is one of the few to survive Ragnarök.
Action Survivor: He actually manages to survive Ragnarök despite never coming across as much of a Badass in what little is known of him. Some have stipulated that he owes his survival just to not being present in Asgard yet at the time of the final battle.
Bit Character: The kind of role he usually has. He is actually mentioned in several myths (often as part of a trio along with Odin and Loki), but he almost never does anything of any real consequence in any of them.
Extreme Doormat: While with the Vanir, he was supposedly incapable of making decisions without Mímir's advice.
Put on a Bus/The Bus Came Back: He was sent away to the Vanir as a hostage in exchange for Njörđr, Freyr and Freyja, but he they eventually send him back to the Aesir when they conclude he is useless without Mímir, and they kick Mímir out too since he is nothing but a talking head, having been decapitated by them in the war.
A god created from the saliva of all the Ćsir and the Vanir, he is the wisest of the gods. He was murdered by the dwarves Fjalar and Galar and his blood was the main component of the Mead of Poetry.
The goddess of the Sun and the god of the Moon (contrary to Classical Mythology, most northern european religions don't see the Sun as masculine or the Moon as feminine), they are sadly the most easily forgotten deities of the pantheon, but seemingly were of quite the elevance, as they even had days sacred to them (Mánadagr, which became Monday, and Sunnundagr, which became Suday). They run across the heavens, running away from two evil wolves that want to kill them.
Action Girl: Sunna, appearently, as she bears a shield and is on war with evil sky wolves.
Composite Character: One of Sunna's epiphets is also shared by Freyja. Both are known as warrior fertility goddesses of golden hair...
Friend to All Children: Máni, who saved two kids, Bil and Hjúki, from their abusive father, who are now his faithful sidekicks.
The blood brother of Odin, Loki is technically a god—one of the Aesir. As in Norse culture, once you are adopted, you are officially one of the tribe—and therefore are a part of the family. So even though Loki was a child of giants (which were the primal forces in Norse Mythology), he was also one of the Aesir. He's a Trickster Archetype who has been often turned into a Satanequivalent.
Alternative Character Interpretationinvoked: Some researchers have theorised that he was originally another aspect of Odin, while a more popular theory is that Loki is the same as Lóđurr, as Loki is often mentioned along with Odin and Hćnir in many tales and it would also explain why Lóđurr is never mentioned again. Some experts say that the benevolent Lóđurr is incompatible with Loki. Note that Loki actually appears rather benevolent in a few stories too. Most experts agree that it's very hard to make a clear statement about Loki's origin and true nature, which is in all appropriate.
Big Eater: In one story he just loses an eating contest to the embodiment of fiery destruction.note Both began at opposite ends of a table and met in the middle. Loki had stripped every bone clean but Logi had eaten the meat, bones, and half of the table!
Canon Foreigner: While most Norse gods have obvious Indo-European roots and equivalents in other Indo-European-derived religions (for example, Thor is a distant cousin of Zeus and Indra, and the Aesir and Vanir are fairly clearly related to the Asuras/Ahuras and Devas/Daevas of Hinduism and Zoroastrianism) Loki doesn't even appear in other Germanic myths. He seems to be unique to Scandinavian traditions and nobody's entirely sure how he got there (which, you know, is appropriate.)
Note that most of the Germanic sources are very scarce and often are second or third hand sources leaving out many gods, so Loki's status could merely be a case of lack of evidence. Same goes for the Frejya/Frigg debate.
Cute Monster Guy: While admittedly giantesses sometimes got the Cute Monster Girl treatment, Loki is a good-looking male giant, and notably, most of his kids (male and female) are hideous monsters.
Determinator: When Loki gives his word he keeps it, whether for good or ill. He'll keep on going even when the likes of Odin have given up.
The Gadfly: When it comes to antics, he is either this or an outright troll. In one story he is a literal gadfly, stinging a dwarf to distract him from crafting better items than those Loki had provided earlier (it was a bet).
Not So Different: Despite all his many, many faults (including promiscuity), he was also quite a family man just like Odin and Thor. Notably he was said to have been raising his kids alone in secret after his first wife died. (That was a BAD thing since they were monsters and Odin subsequently locked them away, but still.)
Playing with Fire: Is sometimes associated with Fire. This may be in part due to him being confused with the character Logi, the personification of fire, who despite what you may think is not just an alternate spelling for Loki. He is also confused with Lóđr/Lódurr, another name for Odin's biological brother Ve, which means burning.
Loki’s giantess consort. The gods abducted her three children when they became aware of how dangerous they would become. Some scholars say she was a very powerful witch and that she had the ability to see into the future. She was confined to Hel and would not be released from the realm of the dead until Loki was unbound.
Beat Still, My Heart: There are several myths that involve Angrbođa’s heart being consumed by Loki. The basic premise is that the Aesir (specifically Odin) ambush her and try to kill her by setting her on fire. There are variations on how that ended too with one version saying she survived the three times she was burned and another version saying that she died the third time with only her heart remaining intact.
One outcome of that has Loki eat her still beating heart to make sure she remains dead
Genre Savvy: In the versions where she does not know the fate of her children, she was cautious enough to make sure the Aesir did know of her children because she knew the gods would see them as a threat.
Sadly she wasn’t always on the ball and when she was summoned by Odin to Asgard she assumed it was because Loki had gotten himself into some deep shit that Sigyn couldn’t help with. What Odin actually wanted was to isolate Angrbođa and kill her so her children would be vulnerable. In this version, what was done to her and their children set the foundation to Loki’s Face-Heel Turn.
Super Strength: There is a story where the gods were trying to launch Balder’s funeral ship, Righorn, but the ship carried so many gifts and offerings they could not move it. Not even Thor could make it budge. In comes Angrbođa and in one swift move she helped launch the ship. Apparently this infuriated Thor so much it took all the Asgardians to hold him back from attacking her.
The Vamp: In the version where she knows her children will help their father end the world.
Loki and Angrbođa's first son, sometimes also called Vanargandr (the monster of the river Ván), Hróđvitnir (fame-wolf) and the Fenris Wolf, the latter being the name by which most modern day Scandinavians refer to him. When the gods learn that he is fated to kill Odin, they bind and seal him when he's still young, with Tyr losing his arm in the process. When Ragnarok comes, he indeed kills Odin, but is killed by Odin's son Vidar in return.
Attack of the 50-Foot Whatever: His final size is such that when he opens his mouth, the lower jaw rests on the ground and the upper jaw hits the sky. In the Prose Edda, it says "he would gape yet more if there were room for it."
Dangerously Genre Savvy: The gods try 'playing' with him by binding him using incrementally thicker chains to no avail, with Fenrir boasting about it. When the gods decide to use thin, fabric-like magical rope, Fenrir quickly deduces the rope is unusual and refuses to play being bound, at least until Tyr gambles his arm so that Fenrir finally agrees to be bound.
Decomposite Character: It is possible that Garmr and Skoll were other names for Fenrir but Snorri wrote them as separate characters.
Glory Seeker: His desire to become famous is what allowed the Aesir to put bindings on him, as he believed facing danger was needed to gain fame. This is seemingly mocked by the other giants who nickname his son Hati "Hróđvitnisson" (Son of famous wolf).
Hero Killer: Destined to kill Odin, responsible for the maiming of Tyr, harbinger of the world's end...yeah he counts.
Roaring Rampage of Revenge: In all probability the reason he kills Odin. He was chained because the gods foresaw that he would cause a lot of trouble if he wasn't (which makes it a Self-Fulfilling Prophecy). Also Odin makes an argument for a person making a name for himself, which could have inspired Fenrir and thus adding to the fire of hate in his heart.
Sealed Evil in a Can: Bound for as long as the Sun and the Moon remain in the sky. Depending on the versions of the myth, his sons, Skoll and Hati, may be trying to do something about that.
Loki and Angrbođa's second son. When he is but a small snake, the gods toss him to the ocean to drown him. But he does not drown and grows big enough to circle the world. He has beefs with Thor, up to the Ragnarok, where the two face off and kill each other.
Sea Monster: The sea monster to end all sea monsters. There isn't an ocean in Midgard that doesn't have a part of him in it.
Loki and Angrbođa's only daughter. Goddess of Death and Graves and ruler of Hel who welcomes the souls of those who died of old age, disease or by accident. She is described as half of her body being that of a regular woman, the other half being rotten like a corpse. The myths never state which half, but people tend to represent it Two-Face style.
All of the Other Reindeer: She was mostly an outcast and generally not very well perceived among all the other Gods and mortals alike.
Dark Is Not Evil: Isn't a malevolent goddess per se, despite what people may think, and keeps her word when she gives it. Hel is actually refered to as a dark and shady place, but a peaceful one.
Hijacked by Jesus: Her realm was originally played as dreary, but not exactly a place of torture. (To the Norse warriors, not going to the warrior's afterlife was the big torture in itself.) Christianity turned it into... well, Hel. And like it says above, she was originally just patchwork coloured, which progressed to either half a skeleton/rotting corpse or half old woman.
The original myths actually state that there are three afterlives. Those who die in battle go to Valhalla and Folkvagnr to prepare for Ragnarok. Those who die of sickness or old age go to Hel, which is dull and dreary, but not a bad place. Those who die after committing what the Norse regarded as sinsnote which in and of itself is a very Jewish/Christian/Muslim term (such as oathbreaking) are punished by being sent to Na-strond, which is described as a monstrous fortress, located somewhere in Hel, woven from the poison-dripping skeletons of serpents, situated behind several deadly rivers, and where the damned wade through sucking blood and have nothing to drink but the urine supplied by a herd of foul-tempered black goats that roam the fortress.
I Love the Dead: In Ynglingatal, it is stated no less than three times that Hel has sex with the dead king. First it is written: "I do not deny that Hel is taking lustful pleasure in the corpse of Dyggvi", then later: "And Loki`s daughter has seduced the ruler of the people of Yng" and last "And Loki`s daughter (Hel) invited the king, the third in the row, to meet for lovemaking from the world of the living".
Overshadowed by Awesome: Seldom seen in the myths, apart from Baldr's death, since she would interfere with the other Asgardians' plans only when it concerned her directly.
Which makes sense, seeing as she was the embodiment of Death and the gods didn't die in every myth. Why would they want to go to her for anything other than resurrection?
Plague Mistress: It was said that when a plague hit the countryside, she would ride from town to town on a three-legged horse with a broom and a rake. In villages where many—but not all—died, she used her rake. But when she used her broom...
Two-Faced: A possible interpretation of her, though her description in the texts is pretty vague - some have taken it to mean she's actually withered below the waistnote like a pale faced corpse while the body fluids drip down turning the lower parts black, get your head out of the gutter.
Loki’s Asgardian wife. Sigyn is known for her role in assisting Loki during his captivity. She would hold a dish over his face to prevent venom from touching it and would leave his side only to empty it. By him she bore two sons, Narfi and Vali.
The Lord of the Fire Giants and King of Muspelheim, Surtr is destined to kill Freyr, and burn the world with the black sword Laveteinn at the peak of Ragnarok while his legions destroy the Bifrost. The real life island of Surtsey on Iceland is named after him.
Canon Immigrant: Some believe he first got his start from Iceland, being based off the volcanic activity around there, through this is being desputed by other experts who belive him to be a very old concept. A typical YMMW-case.
Hero Killer: "At the end of the world he will go and wage war and defeat all the gods and burn the whole world with fire."
Hijacked by Jesus: Is often depicted as a Satan-like figure elsewhere, which is fair considering what he actually does. Through quite a few schoolars think he is an old concept many agree that his flaming sword is a loan from the Bible.
Karma Houdini: Though it's ambiguous if Surtr survives Ragnarok, no one is reported to have killed him during it. One version has him succumb to wounds caused by Frey after burning everything up but most do not.
A giant, that steals Mjolnir, and demands Freya as his wife if they want it back. On the advice of Loki, Thor dresses up as Freya, and eventually retrieves the hammer, after Loki hilariously manages to convince Thrym that Thor is Freya with increasingly unlikely explanations. When Thor retrieves his hammer, he kills Thrym and his sister.
Too Dumb to Live: Probably should have thought a little more about how Freya looked, and maybe should not have stolen the hammer in the first place, or maybe should have demanded a better ransom, or just led the giants to attack Asgard, and abduct Freya, now that they lacked Thor's hammer.
Not to be confused with Loki, Utgarda Loki, was a giant living in Jotunheim, with the alias Skrymir. He challenges Thor, Loki, Thjalfi and Röskva to complete different tasks, each more impossible than the last. Is a rare beast, as he actually survives despite being a giant.
Anthropomorphic Personification: Uses these to defeat the gods. Goes as follows: Hugi, the personified thought, Logi, the personified fire, Elli, the personified old age.
Karma Houdini: In that he actually tried killing Thor, and met no reprise for it.
One Steve Limit: Averted. "Utgarda" isn't actually a part of his name, merely a prefix meaning "of Utgard", probably intended to differentiate him from his more famous namesake.
Our Giants Are Bigger: While he is disguised as Skrymir, whom thinks Mjollnir is just leaves hitting him, and whose gloves are at the size of a house.
Thjassi is a giant who resided in Ţrymheimr and often took the form of a large eagle. He once kidnapped the goddess Iđunn, cutting the gods off their source of immortality, the golden apples Iđunn picked. Iđunn is eventually rescued thanks to Loki's efforts and Thjassi is killed. Thjassi's daughter Skađi later marries Njörđur as a compensation for her father's death.
Kick the Son of a Bitch: He uses some sort of power to prevent Odin, Hćnir and Loki from getting any water in their pot to boil, then when they offer him some meat to get him to stop he leaves them with hardly any. It is not said if the Aesir or Loki actually owned the cattle they were cooking with or not, which would make Thjassi a thief of thieves at best and a regular jerk otherwise.
The personification of fire. In modern days, he is often confused for or combined with Loki, though he is quite explicitly a different person and in fact competes against Loki in the most famous myth in which he appears. He is the son of the jötunn Fornjótr and the brother of Ćgir and Kári.
Big Eater: He not only bests Loki in an eating contest, he devours the entire trencher containing the meat.
Meaningful Name: Logi literally means "flame", and also suits him given his role as Loki's opponent.
Sibling Yin-Yang: His brothers are Ćgir, god of the sea, and Kári, a god of wind.
The jötunn wife of king Logi/Hálogi, presumably to be identified with the personification of fire Loki competed against. Her name literally means "Glow," and she's the mother of two daughters by Logi named Eisa (Embers) and Einmyria (Ashes).
Playing with Fire: Given the meaning of her name and the names of her daughters with Logi, this is a given.
The primeval frost giant, that emerged from the melting ice of Niflheim and Muspellheim at the creation of the world. Was nourished by the milk of Audhumbla, the primeval ox, and were the ancestor to all giants. Was killed by Odin and his brothers, and the world was then created from his body.
Mother Earth: Or, father earth. But he does not personify earth, it was just made from his body after his death.
Mother of a Thousand Young: Technically the father, but given it is birth without female intervention, it doesn't really matter. He fathered new giants constantly while he was still alive, which meant there was already plenty around when Odin finally killed him.
A mountain giant with a triangular stone heart who owned the fastest horse in his world. After coming into Asgard uninvited he gets drunk and causes trouble that leads to him and Thor facing off at Grjottungard.
Cool Horse: Gold mane, which Odin probes him about because the valfather wants it for himself. It turns out to be slower than Slepnir, whom Odin already owns but Odin still whines when Gold mane is later awarded to Magni.
Dishing Out Dirt: His head was as hard as stone, his heart was made of it and he fought with stone weapons.
Duel to the Death: He was the first one to issue such a challenge to Thor, which Hrungner does after Thor berates for him his disrespectful conduct inside the hall of honored dead.
Dirty Coward: Him calling Thor one for threatening him with violence when Thor tells him to get out of Valhalla makes Thor more eager for the duel.
Jerkass: One could see why he was annoyed with Odin boasting about Slepnir but it seems a little much to try to kill Odin over, even for the time period. As he barges into Asgard chasing Odin the other gods assume he is a guest and offer him drinks but he takes their hospitality to mean that he gets ALL of their food and drink. Then he declares he will destroy Asgard and kill everyone after he has finished, except Freyja and Sif. This guy is largely responsible for the giant's bad reputation.
Golem: The giants forged him a partner out of clay, who was nine leagues across at he chest called Mokkerkalfe to help him against Thor, but Mokkerkalfe ended up being afraid of Thor.
Monumental Theft: He wants to take Valhalla from Asgard and move it to Jotunheim.
Our Giants Are Bigger: While Thor does manage to kill Hrungner he is cut by shards of his shattered flint stone(or whetstone) weapon, pieces of which fly from Jotunheim and form a new mountain range on Midgard. His dead weight was too heavy for Thor to lift (because it has fallen on his neck) and all the gods who watched the dual to move off Thor.
Scars Are Forever: A shard of his broken whetstone remained embedded in Thor's head after their fight. It was possible to remove but Thor never bothered to see the procedure through.
The Alcoholic: He boasted that he could drink all the ale in Asgard then set out to do it.
A human boy taken by Thor as a page, as payment for an injury his father did to one of his goats. Despite this rather awkward start to their relationship, he is mentioned in several other stories as a faithful and valuable companion to the Thunder God.
One of the oldest beings in Norse myth, Níđhöggr is a dragon who has existed since creation. It emerged from the Etir, a mysterious and highly poisonous (it's Etir from Jörmungandr that kills Thor) substance from Ymer originated. He sits beneath the entire World Tree Yggdrasill itself, gnawing at its roots. One retelling states that he gnaws on oathbreakers, murderers, and thieves. But he basically stays at the roots, gnawing on them—ensuring they do not overgrow—until Ragnarok, and when he joins in... well, that's when things get really bad for the rest of creation. Of course, he survives it.
Eldritch Abomination: Is typically described in these sorts of terms. The simple fact that he encompasses Yggdrasil's entire root system, and has the power to unmake creation is a bit of a tip off that we aren't dealing with anything normal here.
Omnicidal Maniac / Necessary Evil: One interpretation of his reasons for eating the roots of the World Tree is that he's actively trying to tear it down, though another is that he's a Necessary Evil so the roots won't overgrow.
