In modern literature (such as Marvel Comics) it has become popular to portray Loki as the adopted son of Odin. This however has no basis in Norse mythology, where Loki is portrayed as the blood brother of Odin.
Laufey was the king of the Frost Giants of Jotunheim, and the biological father of Loki. He was betrayed and killed by his own son while attempting to start a second war between Jotunheim and Asgard by murdering the Asgardian King Odin.
The son of giants, Loki is actually considered to be a type of Jotunn or giant rather than a member of the Aesir, the ruling class of gods in Norse mythology. He is the "blood-brother" of Odin, the Aesir king, and the husband of the goddess Sigyn.
While Marvel's Loki is the adopted son of King Odin and the biological child of Laufrey — the king of the Frost Giants of Jötunheimr — this differs from the original mythology. In some stories, Laufrey is depicted as a female, making Loki's father actually his mother.
With Sif, Thor fathered the goddess (and possible valkyrie) Þrúðr; with Járnsaxa, he fathered Magni; with a mother whose name is not recorded, he fathered Móði, and he is the stepfather of the god Ullr. Thor is the son of Odin and Jörð, by way of his father Odin, he has numerous brothers, including Baldr.

Loki has changed role and aspect many times, but he is still mostly remembered as Thor's antithesis, his resentful adoptive brother who grew up to hate the God of Thunder. One of the reasons for Loki's bitterness is that Odin always favored his "real" son, Thor, during their childhood.
The appearance of Odin was used by Loki to rule the Asgardians for some time after Loki's faked death on Svartalfheim. While ruling Asgard as Odin, Loki cast a spell on his father to make Odin forget himself and exiled him to Earth, leaving him dazed at Shady Acres Care Home: a retirement home in New York City.
Ages ago, Odin fought and defeated Laufey and the Frost Giants of Jotunheim in a great war. Abandoned and left for dead as a baby due to his diminutive size, Odin took Loki, son of Laufey, to Asgard to raise him as his son and a prince in order to one day unite the Frost Giants and the Asgards in peace.
Loki is married to Sigyn and they have two sons, Narfi or Nari and Váli. By the jötunn Angrboða, Loki is the father of Hel, the wolf Fenrir, and the world serpent Jörmungandr. In the form of a mare, Loki was impregnated by the stallion Svaðilfari and gave birth to the eight-legged horse Sleipnir.
Answer and Explanation: Since Odin was a wanderer and traveled the cosmos, he could have fathered many children. However, in Norse mythology, his sons are the gods Thor, Baldr, Hoor, Vioarr and Vali (but there are variations of this in the Norse texts).
By saving and organizing every existing timeline, Loki has become the God of Time — a higher being who keeps the past, present, and future of every universe from being erased by outside forces. However, Loki has also become the God of Stories, as he has placed everybody's personal journey above his own.
Here, holding on to all of the timelines, he became a kind of tree god, physically representing the Norse tree of life, Yggdrasil. It was a poignant and painful ending for Loki, who now seems to be sentenced to being alone for eternity as he watches over the timelines.
The chaos the deities face, such as the destabilization of the world-tree and Fenrir's escape, leads to Loki freeing himself. During the battle, Loki eventually begins to fight Heimdall, who guards the entrance to Asgard. The two ultimately engage in a battle to the death, killing each other during the conflict.
So while Zeus' best feat is defeating a mountain-sized monster, Odin's best feat is defeating a monster as big as nine worlds. Odin outclasses Zeus in intelligence, versatility, strength, and weapons. Zeus simply can't compete. The winner is Odin, All-Father of the Æsir.
In the Marvel Universe, Odin is basically the Superman of Asgardians. Whatever Thor can do, he can do better—there's a reason it's not called the "Thor Force."
In the Marvel Cinematic Universe (MCU), why did Odin love Loki more than Thor? In the end, Odin loved both his sons equally. And at the end (or so we thought), Loki finally acknowledged Odin as his father as well.
This stemmed from his childhood and the belief that Odin didn't love him. While Odin's hiding of Loki's true parentage and Thor's demeaning behavior may have influenced Loki, ultimately he is to blame for his villainous actions due to his own issues with self-acceptance and misinterpretation of his upbringing.
Loki is Thor's adopted brother and the Asgardian god of mischief. In his younger years, he and Loki were very close and good friends, even if occasionally irritated by Loki's mischief. However, it is later revealed that Loki was often jealous of Thor even back then, and resented being left in his "shadow".
This interrupted Thor's coronation and was part of Loki's overall plan. He later revealed that he did this simply to mess with his brother Thor on what should have been his big day on Asgard.
In Norse mythology, Heimdall was one of the Aesir, watchman of the gods, guardian of the heavenly realm of Asgard, and ruler of holy places. His father was the principal god, Odin, and according to the 'Prose (or Younger) Edda', he had not one but nine mothers; they were maidens who were sisters.
Although they are commonly represented as brothers in modern literature and representations, traditionally they were not considered brothers. Loki became blood brothers with Odin, Thor's father, after they participated in a blood-sharing ritual. Loki is thus Thor's adopted uncle, not his adopted brother.
This is precisely the case with Vali Halfling, Loki's long-lost son. As the product of both a complicated backstory and an especially convoluted plot, Vali's comic book career didn't last long.
