Jane is Loki's significant other, his romantic interest, the mother of his children, and, by all intensive purposes, his wife. In the main verse, the two are currently in a relationship and rule over Svartalfheim, after the malicious Malekith ingrained himself into Jane's body, using her as his vessel. In the medieval AU, Loki and Jane are married and the current rulers of the nine realms; a reign that is proving to be shaky and very disruptive. They have a son, Linus. In certain threads, Loki and Jane are not together, due to the effects of the spell Loki cast on her to save her life from Malekith’s influence. Instead he maintains a constant watch over her, but unable to approach her due to the premise that her life would be placed in danger if she remembers who she is. No matter what verse Loki exists in, his love and affection are reserved solely for the astrophysicist, and he is willing to go to any and all lengths to protect her and guarantee her safety.
Jora is Loki and Jane's firstborn. She was conceived while Jane was an Aesir, making her one of the very few Jotun-Aesir in the nine realms. She is said to be physically similar to her mother, with long, brown hair, pale skin, and thoughtful doe eyes. However, she has also inherited her father's ability to turn into a Frost Giant, though she hardly uses this ability. Jora is protective of her family, but she also enjoys playing pranks with and against her younger half-brother, Linus.
Linus is Loki's son with a Midgardian woman, who died giving birth to him. The God of Mischief was unaware of Linus's existence, and he and Jane stumbled upon Linus while running from S.H.I.E.L.D. It didn't take long for Loki and Jane to grow close to the boy, which was only strengthened once Loki learned that Linus is his son. Loki and Linus are physically similar, and share the same mischievous interests. Unlike his "older" half-sister, Linus doesn't mind turning into his Jotun appearance, and is even fond of spending time in Jotunheim.
She is the only mortal whom Loki trusts completely, and they have known each other for many years. Loki met her in Asgard, where she had gone after the death of someone very close to her. Unlike most mortals, Ana has special demonic abilities that were granted to her in exchange for her soul. This allowed her to visit Asgard and gain the friendship and trust of the younger prince. Shortly before Thor’s coronation Ana disappeared; only to resurface a year later in S.H.I.E.LD., where she and Loki were reunited. She is currently part of the tactics division of the organization, and occasionally goes on several missions with Loki.
Sigyn and Loki have a very complicated relationship, mostly due to the latter's romance with Jane Foster. Before Loki learned of his true heritage, the two had a slightly rocky, yet at times loving, union. Now, however, it has been quite difficult to define. An alternate storyline caused them to adopt a baby girl, whom they named Eisa.
Sigyn is Loki’s mentor and abused wife, both in different AU verses. As his mentor, Sigyn teaches the God of Mischief how to be an effective thief or to survive in the wilderness. As his abused wife, Sigyn and Loki have a love-hate marriage, where Loki feels that he cannot fully trust her. Unlike in mythology, Sigyn and Loki do not have any children in any of the verses.
Sigyn and Loki are classmates who hate each other, but eventually a friendship forms between them that would lead to Loki becoming known as the God of Mischief and Sigyn as the unknown mastermind behind most of his antics and pranks. As adults, Loki and Sigyn have a less than civil relationship, due to Loki's intimate connections with Jane Foster.
Silver is Fallen’s older, more malicious counterpart. They are considered as two sides to Loki’s personality, but Fallen loathes being considered as Loki’s good side, for he is aware that he is not completely good. The two are currently in Asgard, with Silver serving time in the Asgardian prison, and Fallen finding a way to help his twin out of prison.
She is Loki’s servant and currently uses his apartment as her home until she finds an apartment of her own. Lottie is very protective of Loki but hates being the target of his pranks and scathing remarks. Loki occasionally calls her “Little Lottie”.
Alsoomse is a member of the Shawnee tribe, whom Loki meets during one of his frequent jaunts to Midgard. Initially, he considered her as one of the many damsels in distress, despite the fact she was carving the skin off an animal she'd hunted. It didn't take him long to realize that there was more to this mortal woman than he first thought, and secretly admires her and her tribe. He has also taken upon himself to protect the Shawnee from invading foreigners by causing mischief.
Hel (or Hela) is Loki's daughter from the Jotun giantess, Angrboda. After his return to Midgard, Loki learns that she has been exiled by an unknown individual, and helps her regain her position and stature as ruler of Helheim. He recognizes her importance in ferrying the souls to their final destination, and convinces Odin to return her powers to her. He shares her disdain and hatred of the All-Father, and is protective towards her.
