The main characters of Loki - Loki, Sylvie, and He Who Remains - all originate from different points in time, raising questions about their ages. Loki is around 1,050 years old, Sylvie is around the same age as Loki, and He Who Remains has been alive for a very long time, possibly eons.
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.
Looking at the aging of Frost Giants in the MCU and the age of the actress playing Sylvie, it makes sense that she too is close to a thousand years old. Odin confirmed in Thor that Asgardians, who aren't actual immortals, age like humans do, just slower.
Thor Odinson himself said he is around 1500 years old at the time of the events of Infinity War (2018), and MCU fandom wiki mentions Loki's year of birth as 965 AD, hence he would be 1055 years old at the time of his death in 2018. So, Thor is around 445 years older than Loki.
Based on calculations from a Tumblr user, Loki is around 16 "human" years old in the Marvel Cinematic Universe, which explains his petulance in his early appearances.
In the MCU, it is confirmed that Loki was 1,054 years old when he was killed by Thanos in Avengers: Infinity War. The Asgardians are far older in the comics than they are in the movies, so Loki is likely thousands if not tens of thousands of years old.
This makes Thor 447 years OLDER than Loki who, we can reasonably assume, was born in 965 (AD) as shown at the beginning of Thor (2011). Thus, in Thor: Ragnorak (2017) Thor would have been 1,499 years old, and Loki would be 1,052 years old.
In his comic book appearances, Loki is depicted as the Asgardian God of Mischief, a cunning trickster, and a master of Asgardian magic and sorcery. After learning of his true origin as a Frost Giant from Jotunheim, Loki grows jealous of Thor and frequently plots to take the throne of Asgard for himself.
A different interpretation of the theory says Odin intentionally changed Loki's appearance and made him look like Hela. In order to keep the baby safe, Odin had to make him look like a human immediately, but instead of making him look like Thor, he chose Hela, as a constant reminder of his daughter.
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.
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.
In the comics, there is no difference. She isn't an alternate version, one that has escaped the main timeline. She is the Loki we all know and love. You have to remember, Marvel based their God of Mischief on Norse mythology in which the trickster god is genderfluid and often appears as a man or woman.
No. In the comics yes, he posed as a girl to trick Thor. In the MCU there are AU Loki variants but they are not the Loki who stars in the series. It's almost like Loki doppelgängers from different universes.
In Norse mythology, and in the Marvel comic books, Loki has always been gender fluid, capable of changing genders at anytime for any reason. But before the show, the MCU version of Loki had always been male-presenting.
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.
The etymology of the name Loki has been extensively debated. The name has at times been associated with the Old Norse word logi ('flame'), but there seems not to be a sound linguistic basis for this.
Loki is considered a trickster god, known for being neither fully good nor evil since his main aim was always to create chaos. Despite his father being a giant, he is still counted a member of the Aesir—a tribe of deities including Odin, Frigg, Tyr, and Thor.
While Steve Rogers gets the title of the oldest human avenger, Thor Odinson, as the mighty Asgardian God of Thunder, has a much longer life span than any of his Earth-born friends.
The Horned Helmet was the helmet Loki wore during his time as Asgardian royalty and his crusades. Its horns are an Asgardian symbol for the sorcery he wields. Other Variants of Loki also have their own helmets with different shape.
Loki is considered to be the son of the Jotunns Farbauti and Laufey, and the brother of Helblindi and Byleistr, also Jotunns. The exact fates of Loki's biological family are left unclear, and his eventual relationship with Odin and the rest of the Aesir is equally mysterious.
Asgardians age as humans do for the first 20-or-so years of their lives. Upon reaching early adulthood, they begin to age much more slowly. Asgardians possess different internal anatomy from humans, with their bones, tissue, and skin denser.
"Loki Is About 16 Years Old In The MCU In Thor: The Dark World, Odin reminds Loki that Asgardians are not immortal and have lifespans as humans do, to which Loki responds: "Give or take 5,000 years." From this, it can be calculated that Asgardians live to about 5,100, with Loki being around 1050 years old in the MCU."
