Loki is a trickster half-Jotunn Norse god, While treated as a nominal 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. He is the father of Hel, Lady of the Dead, Jörmungandr, the World Serpent and Fenrir, the Wolf.
Loki is sly, manipulative, charming, humorous, mischievous, quick to anger, and cruel when he needs to be. Loki is also extremely persuasive, to the point that he once successfully convinced Ran to lend him her magic net.
Despite his negative traits, Loki does harbor affection for his children, especially Vali and Narfi. Loki is very upset and grieved about the shocking fate that his sons Vali and Narfi suffered as part of Loki's punishment for killing Baldr - with them being slain by the gods, and their entrails used instead of ropes to bind Loki to a the slab of rock under a serpent.
Loki has long red messy hair and a short goatee. 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, with his gaze flitting restlessly, like fire in a hearth, pushed by the wind, looking for anything it could set ablaze.
Illusions: Loki can cast illusions of himself anywhere he pleases. He can still enter demigods' dreams, even as his actual body remains securely imprisoned (until Ragnarök).
Shapeshifting: Loki is able to change into various forms including, but not limited to, a salmon, a mare (in this form he even gave birth to the colt Sleipnir), a seal, a fly, and an elderly woman called Thokk.
Serpent Venom Pain Transferal: Loki is able to make the latter feel the extreme pain that the serpent venom causes when it drips onto the trapped god's face from time to time.
Consciousness Splintering: Despite being securely imprisoned by the gods, Loki can still make part of his consciousness materialize into another physical body from time to time. If done incorrectly, however, this process can cause him intense pain.
