Loki Laufeyjarson-Loki is a practical joker in the Norse pantheon. He is a part god, and part giant, who was a member of the Aesir for a long time. The trickster god is a complex character, a master of guile and deception. Loki was not so much a figure of unmitigated badness as a kind of celestial con man, who always managed to persuade the gods to give him another chance. Some anthropologists have compared him to Coyote, a trickster figure of Native American mythology. Loki can at times be reminiscent of the Chinese Monkey King whose persona in myth underwent changes over the centuries.
Loki is an adept shape-shifter, with the ability to change both form (examples include transmogrification to a salmon, horse, bird, flea, etc.) and sex. According to some scholarly theories Loki is conceived of as a fire spirit, with all the potential for good and ill associated with fire. However, this view is probably due to linguistic confusion with logi "fire", as there is little indication of it in myth where Loki's role is predominantly associated with Wöden, either as Wöden's wily counterpart or antagonist.
Together with the giant Angrboda, Loki had three children, Fenris the giant wolf; Hel, goddess of the dead; Sleipnir, the eight-legged steed of Wöden; and Jörmungandr the seaserpent. Sleipnir was conceived when Loki tricked the mason hired into rebuilding Asgard's walls (Blast) into finishing late, forfeiting his payment. He also retrieved Gungnir (Wöden's spear), Skidbladnir (Freyr's ship) and Sif's wig from Dvalin, the dwarf, as well as rescuing Iôunn. Finally, in Þrymskviða, the funniest of Thor's adventures, Loki manages, with Thor at his side, to get Mjolnir back when the giant Thrym secretly steals it, in order to ask for fair Freyja as a bride, in exchange.
Loki may have overplayed his hand when, disguised as a giantess, he arranged the murder of Baldr (he used mistletoe, the only plant which had not sworn to never harm Baldr, and made a dart of it, which he tricked Baldr's blind brother Höðr into throwing at Baldr, thereby killing him).
The Aesir, bereft at the loss of Baldr, sent Hermod, another son of Wöden, on Sleipnir to the underworld to bargain for Baldr's life; there, Hel told them that the only way to ensure the god's return was to have everything in the land weep for him. The Aesir went through the land, and convinced not only men, women and animals to weep for Baldr, but also rocks and trees. Finally, they arrived at a cave in which a giantess dwelled. The Aesir were unable to convince her to cry for Baldr, and so he remained in the underworld. When the gods discovered that the giantess had been Loki in disguise, they hunted him down and he was forced to flee. He hid by night as a salmon beneath a waterfall, and by day he idly wove nets and burnt them.
One day the Aesir found his fireplace at night, and found a net in the fire. From its design they created another, which they used to catch Loki. They bound him to three rocks with the entrails of either his son Narvi. Then they tied a serpent above him, the venom of which dripped onto his face. His wife Sigyn (a goddess, not the giantess who was the mother of Loki's monster brood) gathered the venom in a bowl, but from time to time she had to turn away to empty it, at which point the poison would drip onto Loki, who writhed in pain, thus causing earthquakes. He would free himself, however, in time to attack the gods at Ragnarok along with the other giants and his monster children.
Loki could be a friend to man. For instance, when a thurs (troll or giant) came to take a farmer's son away, the farmer and his wife prayed to Wöden to protect him. Wöden hid the son in a field of wheat, but the thurs found him. Wöden rescued the son and took him back to the farmer and his wife, saying that he would no longer hide the son. The couple then prayed to Hœnir, who hid the son in the neck-feathers of a swan, but again the Thurs found him. On the third day, they prayed to Loki, who hid the son amidst the eggs of a flounder. The thurs found the flounder, but Loki instructed the boy to run into a boathouse. The giant got his head caught in a hole whereupon Loki killed him by chopping off his leg and inserting a stick and a stone in the leg stump to prevent the thurs from regenerating.
