In the form of a mare, Loki was impregnated by the stallion Svaðilfari and gave birth to the eight-legged horse Sleipnir. Loki's relation with the gods varies by source; he sometimes assists the gods and sometimes behaves maliciously towards them.
According to the myths, the evil Loki himself gave birth to Fenrir, after eating the heart of a giantess, the witch Angerbotha. After his birth, the gods received prophecies of disaster concerning Fenrir and his siblings. Even when Fenrir was a pup, the only god courageous enough to approach him was Tyr.
With the female giant Angerboda (Angrboda: “Distress Bringer”), Loki produced the progeny Hel, the goddess of death; Jörmungand, the serpent that surrounds the world; and Fenrir (Fenrisúlfr), the wolf. Loki is also credited with giving birth to Sleipnir, Odin's eight-legged horse.
The monsters were conceived after Angerbotha had been burnt by the gods as a witch. Loki was the god who ate her heart. According to the story, the flesh of Angerbotha's heart fertilized Loki so that he became impregnated with the monsters. He then gave birth to them.
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.
Mating with the goddess Angerboda, they produced three offspring: Jormungand (the Midgard Serpent), Fenris Wolf, and Hela, the goddess of death. Sticking to his wicked ways, Loki deceived the goddess Sigyn by posing as her true love, Theoric, and convinced her to marry him.
And so the gods agreed that Loki's children must be captured. At Odin's behest, a group of gods crossed into Jotunheim by night ; they burst into Angrboda's hall and gagged and bound her before she had even rubbed her eyes; then they kidnapped her children and carried them back to Asgard.
Floki as Loki
Floki principally worships Loki and believes himself to be a descendant of the God. Ragnar notices that Floki is a lot like Loki, only not a god. King Horik and Floki quip over a story about Loki stealing a necklace that belonged to Freyja while in the shape of a fly.
“What am I?” Odin explained that ages ago, he fought and defeated Laufey (Colm Feore), King of the Frost Giants. That's where he found the child Loki, who, abandoned and left for dead, was taken to Asgard and raised as Odin's son in the hopes that he would one day unite the Frost Giants and the Asgardians.
In chapter 50 of Gylfaginning, to punish Loki for his crimes, the Æsir turn his son Váli into a wolf and he dismembers his brother, "Nari or Narfi", whose entrails are then used to bind their father.
Loki shapeshifted and turned himself into an alluring female horse to draw Svaðilfari away from helping the master builder complete Asgard's fortifications. When they were together, Loki and Svaðilfari mated. Loki subsequently became pregnant and gave birth to Sleipnir.
How many times does Loki get pregnant? Sigyn is introduced as being married to Loki, and they have a son named "Nari or Narfi". Otherwise, Loki had three children with the female jötunn Angrboða from Jötunheimr; the wolf Fenrir, the serpent Jörmungandr, and the female being Hel.
In Norse mythology, Svaðilfari (Old Norse: [ˈswɑðelˌfɑre]; perhaps "unlucky traveler") is a stallion that fathered the eight-legged horse Sleipnir with Loki (in the form of a mare). Svaðilfari was owned by the disguised and unnamed jötunn who built the walls of Asgard.
It's generally assumed that Floki was more on the lines of schizophrenia due to his religious delusions and erratic manners, though some have suggested that he might have been autistic.
"The Seer totally rejuvenates him in one way."
In a surprising turn of events, the Seer licked Floki's hand, bestowing a sign of respect back on the troubled Viking. "At that point, Floki's a broken man," Skarsgard explained to IGN during a visit to Vikings' Ireland set.
As not much is known about the religious practices of the Vikings, those seen in the series are mostly fictional, and licking the hand of the Seer came up as a sign of respect towards someone with contact with the gods. This gesture has also made way for a fan theory regarding Floki and the new oracle.
But if we consider physical strength and raw power, Fenrir, the monstrous wolf, is often regarded as the strongest of Loki's offspring. Fenrir's immense size and strength instilled fear in the gods, who tried multiple times to bind him with chains.
Hela is the child of Loki, God of Mischief, and the giantess Angrboda. Hela's face is withered and decayed because she was mystically born half dead, but wears a cloak that conceals this imperfection, and while wearing it, she appears to be a beautiful woman.
Loki has a wife whose name is Sigyn. He has had relations with several others, but Sigyn is his only wife.
Sigyn (pronounced roughly “SIG-in”) was the wife of the wily trickster god Loki. Eddic and skaldic poetry are peppered with passing references to this role of hers, attesting to her existence in the Germanic pantheon from early times.
After he's captured by the TVA, Loki's tasked with helping it track down a variant of himself — Sylvie, a female Loki hellbent on revenge against the Authority. After facing down an apocalypse together, the two fall in love, which has reality-shattering implications.
Loki will be bisexual and have both a male and a female love interest in an upcoming Disney+ series, according to an industry insider.
Sigyn “Sig-in” After Odin learned of Loki's marriage to the giantess Angrboon, he broke it off, and had Loki marry one of their own; Sigyn of the Aesir. So little is known about this goddess, that they do not know what she was the goddess of.
Sigyn appears in the books Gylfaginning and Skáldskaparmál in the Prose Edda. In Gylfaginning, Sigyn is introduced in chapter 31. There, she is introduced as being married to Loki, and that they have a son by the name of "Nari or Narfi".
