Loki is the Norse Aesir half-Jotunn God of Mischief and an antagonist in the Magnus Chase and the Gods of Asgard trilogy. While treated as a normal member of the Aesir tribe, he is known to switch his allegiance often and is destined to ultimately side with the giants and lead them against the gods. Due to being genderfluid, Loki can change gender. As a male, he is the father of Hel, Lady of the Dead, Jormungand, the World Serpent, Fenris, the Wolf, and the demigod Samirah al-Abbas. As a female, she is mother of Sleipnir (due to taking on the form of a mare to give birth to him) and the demigod Alex Fierro (whom like Loki, is genderfluid). He is based on Loki from Norse mythology.
Loki caused the death of Odin and Frigg's son Balder by making a spear from mistletoe (the only thing vulnerable to Balder) and gave it to Balder's blind brother Hodr who throw it and it killed Balder.
The gods punished Loki for this by binding him to a rock with the entrails for his sons Vali and Narfi, which a snake above him which would drip it's venom onto Loki's face, causing him pain of which would cause earthquakes.
Despite being bound to the rock, Loki can still produce manifestations of himself to appear in Midgard.
Magnus Chase and the Gods of Asgard
The Sword of Summer (2015)
Loki frequently appears in Magnus Chase's dreams to convince him to give up tying the Fenris Wolf. The first time was when Magnus died. The second was after Magnus' first battle practice where he told Magnus he would eventually sit on Odin's throne. The third was when Magnus and friends jumped into a river to get out of Nidavellir the land of the Dwarves and promised he would be reunited with his mother Natalie in Helheim if he gave the sword of summer to his uncle Randolph. Loki hopes to bring Ragnarök by manipulating Randolph.
After Magnus re-tied his son, Loki appears in Randolph's office, revealing he was the priest at Magnus' funeral. Loki gives Randolph a burn scar on his face for failing him. He says that there are many triggers for Ragnarök.
Loki has dirty blonde feathery hair (with red, blonde, and yellow tints), tousled in a fashionable I-just-got-out-of-bed-and-I-look-this-good sort of way, and he is seen wearing a Red Sox jersey, jeans, and white tennis shoes. Loki is considered shockingly handsome, though his appearance is somewhat ruined by his scars - burn tissue splashed across the bridge of his nose and his cheekbones (caused by the snake venom dripping onto his face), like impact lines on the moon's surface, while Loki's lips are marred by a row of welts all the way around his mouth, much like many piercing holes that had closed over (marks from the time his lips used to be sewn together by the dwarves).
Loki's eyes have an intense glow to them, much like those of his daughter Samirah, with his gaze flitting restlessly, like fire in a hearth, pushed by the wind, looking for anything it could set ablaze
Loki is sly, manipulative, charming, humorous, mischievous, quick to anger, and cruel when he needs to be. Despite this, he does have affection for his children, especially Samirah and his sons Vali and Narfi (the latter two were slain by the gods and their entrails were used as ropes to bind Loki to a slab of rock under a serpent as punishment for Loki killing Balder, the Norse Aesir God of Light).
- Loki has the ability to change gender as he once took the form of a mare (a female horse) and mated with a stallion (a male horse) named Svadilfari which resulted in the birth of their son Sleipnir, a horse with eight legs and became Odin's steed.
