Fatherly summed up the character as: "While the comics imply that some version of Loki created Sylvie, they are not the same character. What the Loki series has done is seemingly combined the character of Sylvie and Lady Loki into a new person: a Loki Variant who uses the alias 'Sylvie.
A romantic fling between Loki (Tom Hiddleston) and a Loki variant (Sophia Di Martino). Aka a female version of Loki, their relationship of sorts labeled by some as "incest." Technically, Loki and Sylvie aren't brother and sister, but different versions of the same person.
The two trekked to a nearby town, and the two argued on the way, especially how Sylvie was a Variant but did not like to be called one, and also did not like to be called Loki. She then told him her name was Sylvie, and Loki told her that having an alias was not Loki-like.
Canon. Loki and Thor are brothers, and Loki and Sylvie are variants of each other from alternative timelines. Due to the time-travel aspect of the Loki series, there are some variations in the canon/history of each character in this relationship.
At some point in her life, she crafted a new identity for herself, changing her hair color and abandoning the name "Loki", calling herself "Sylvie" instead.
Despite their initial lack of trust, Loki and Sylvie developed a special bond and fell in love during the first season. Sylvie's actions in killing He Who Remains will have consequences that affect both her and Loki's personal journeys in the upcoming season.
Loki and Sylvie's Romantic Relationship Was Totally Abandoned. After Sylvie kills He Who Remains, the timeline branches out and the multiverse is created. Instead of recognizing that her decision was erroneous, Sylvie refuses to help Loki when he asks for assistance restoring the TVA.
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.
So yes, there are cosmic roles that match from universe to universe, but they aren't from the same genetic starting point. Loki and Sylvie are not from the same universe. They are separate Loki's from separate universes.
Sylvie Laufeydottir (born Loki Laufeyson) is a fictional character portrayed by Sophia Di Martino in the Marvel Cinematic Universe (MCU) media franchise, partially based on the characters Lady Loki and Sylvie Lushton's Enchantress from the Marvel Comics.
Sylvie Laufeydottir means Sylvie, the daughter of Laufey. Laufey was the king of Frost Giants, who was killed by Loki in the main MCU timeline. He was also the father of Loki. Sylvie is the dangerous variant that the Time Variance Authority has been hunting for.
The TVA had taken Sylvie from Asgard as a child because she caused a Nexus Event that threatened the stability of the Sacred Timeline, meaning she had spent her entire life on the run from the omnipotent organization, though the exact nature of her Nexus Event wasn't actually revealed.
Her character is a mix between Sylvie Lushton (the second Enchantress) and Lady Loki, but she is a female variant of Loki who took up the alias of Sylvie.
Why Sylvie Steals the Show in Loki: Season 2. We suppose it's not really false advertising for Sylvie to replace Loki as the emotional heart of the series. She may not be the Loki, but she's still a Loki. She's a Loki who grew up in very different circumstances from the MCU version, and she has an agenda all her own.
What is Loki the god of? Loki was regarded by the ancient Norse people as the god of mischief, trickery, and deception. He was also seen as the father of several gods and Jotunns, including Sleipnir, Hel, Jormungandr, and Fenrir.
Sigyn was an Aesir goddess and the wife of the trickster Loki. She is portrayed as loyal and dutiful but may have secrets to reveal. While Sigyn was one of the Aesir gods of Asgard, she was also the wife of the trickster Loki. He was a giant invited to live among the Aesir due to a brotherhood pack with Odin.
He also had numerous affairs with men, women, and even a horse. That doesn't fit our modern idea of a faithful and loving marriage. But there's also no mention anywhere of Loki being forced to marry Sigyn.
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.
It's worth pointing out that Loki and Thor are not brothers, adopted or otherwise, according to most mythological accounts. The child of Frost Giants Fárbauti and Laufey, Loki impressed Odin, earning his place among the gods.
Why did Loki turn into a woman? In the comics, Loki is reborn as a woman, known simply as Lady Loki, after the events of Ragnarok in Asgard, but even that wasn't too innocent: When Thor and his fellow Asgardians are to be reborn in new bodies on Earth, Loki actually stole the body intended to be for Sif.
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.
During season 1 the two had an obvious romantic relationship growing. By the middle of season 2 it seems that the feelings ended, and while Loki still cared about her, though perhaps platanocly, she didn't seem to care him anywhere near as much.
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.
