Sigyn: I’ve talked a bit about Sigyn before in a previous headcanon. [Diane Kruger would be Sigyn’s FC.]
(She totally has that “GFDI Loki” face down.)
Vali and Narfi Lokason (Both deceased): Children of Loki and Sigyn, Vali and Narfi were less than a decade apart in age, with Vali being the elder son. Sigyn raised her boys to be princes like their father. Both of them have features similar to both parents.
[Ulrik Munther would be Vali’s FC]
[Asa Butterfield would be Narfi’s FC]
Angrboda: As a frost giantess, Angrboda has pale blue skin color and white hair. Angrboda was ostracised from most of Jotun society due to her “perversion.” In Jotun society it was considered perverted to be one gender or another and Angrboda was always stuck as a female. She lived on the outskirts of Jotun society, traveling from one place to stop and rest to another. It was through her travels that she encountered Loki, who had disguised himself as a frost giant at the time, unaware that he already was one. Through their single love affair, Angrboda bore three children.
[Katheryn Winnick would be Angrboda’s FC]
Fenrir Lokason: Of the triplets between Loki and Angrboda, Fenrir is the eldest, being first born. He prefers the incarnation of a wolf most and that was the form he was originally born in. He appears as a fully white wolf. This is optimal for any frost giant’s child to be able to hide in the snow. Fenrir is about 16 feet tall.
[Michael Fassbender would be his humanized FC]
Hel Lokadottir: Of her womb-mates, Hel is the palest and one who prefers the human form as her natural appearance. She has platinum-blond locks that she inherited from her mother and has her father’s vivid green hues. With a face that appears dead to emotion and mind mostly free of irrationality, Hel was born to be a ruler. Her striking appearance could silence a room and this is why she has been often referred to as the “half dead girl.” Hel stands 6 feet tall, only two inches shorter than her father, however her mother stands taller than both herself and her father. Her shortness was perhaps a genetic anomaly.
[Emilia Clarke would be her FC]
Jormungandr Lokason: Jormungandr is the last born of Loki and Angrboda’s triplets. Liefully’s Jormungandr is a male. Jormungandr was born as a snake hatchling. He grew exponentially to be able to circle the Earth once. He has a head that most appears like the head of an anaconda. The circumference of his body is 5 times as big, if not bigger, than the circumference of his head. Jormungandr looks as black as obsidian all along the scales of his back and sides and his belly appears as a dark blue-gray.
[Ben Barnes would be his humanized FC]
Svadlifari: Loki absolutely dislikes speaking of him, though Svadilfari is a part of Loki’s life. In a completely non-consensual union, their son, Sleipnir was born. Svadilfari is the only parent of one of Loki’s children that Loki refuses to speak to. Svadifari is a giant steed, entirely black in appearance.
Sleipnir Lokason: While Loki absolutely hates the events that occurred for Sleipnir’s conception, Loki loved his child just as much as he loved any other. Sleipnir is the only child that Loki mothered. Sleipnir is perhaps one of Loki’s most quirky children. Both Loki and Thor disapprove of Odin treating Sleipnir like any other steed.
[Cody Christian would be Sleipnir’s humanized FC]
Natasha Romanov (Possibly deceased?): While Loki never actually bedded her, Romanov was given the misfortune of becoming pregnant with his child. After about a month of stress and tension, the two discovered that not only was their child actually human in appearance, it would be a daughter.
[Scarlett Johansson is Romanov’s FC]
Sophia Kata Romanov-Lokadottir (Possibly deceased?): The unborn offspring of Loki and Romanov, Loki had the privilege of interacting with his daughter as an 18 year old for a week when a spell was cast to grant his heart’s content. Romanov and their unborn daughter disappeared under mysterious circumstances. Loki doesn’t know what happened to them but he fears the worst.
[Karen Gillan is 18 year old Sophia’s FC]
