In Loki Episode four, “The Nexus Event,” we see the return of Jaimie Alexander as the Asgardian warrior Sif. This character apparently never disappears, despite being written outside of the off-screen MCU. (And later ignored in several later projects.) You just can’t keep this badass immortal warrior.
In Loki, Sif appears as part of a time loop meant to break Loki, in which he relives a painful moment on several occasions. The one where Sif knocks her ankle off after cutting a huge chunk of her hair. This moment is in fact directly from the Norse myth. In ancient tales, Loki cut Sif’s hair while she slept like a prank. This angered Thor so much that he forced his crook brother to forge a gold helmet to replace Sif’s missing locks.
They also recreated that moment in Marvel Comics, specifically in Thor Annual # 11, in 1983. In the Marvel Universe, Loki cut Sif’s golden hair in a moment of childish jealousy. While she was sleeping peacefully. Later, Loki made a deal with dwarves Eitri and Brokk to shape new Sif hair, fearing that Sif would seek revenge. Since Loki never paid the dwarves, they made Sif’s hair black when placed on his head. This explains why the legendary golden-haired Sif has black hair in the comics.
But it’s been a minute since we’ve seen this character in the Marvel Cinematic Universe. Here’s a reminder on Asgardian warrior goddess Lady Sif, just as she makes her welcome return to the MCU. The one that will continue next year Thor: Love and thunder. And, hopefully, beyond.
First Thor film, Lady Sif was a constant companion of Thor and the Three Warriors. The group faced off against the Frost Giants of Jotunheim in the perceived attack on Asgard, almost starting a war. Sif appeared to be much more balanced than Thor and his friends, but was just as fierce a warrior. Sometimes his temper prevailed.
Once Odin stripped Thor’s powers and his exile to Earth began, she disobeyed the orders of the new King Loki and went to Earth to save her friend. Referred to by distraught ordinary Earth mortals as “Xena,” she aided in the final battle against the Destroyer on Earth. Thanks to them, Thor returned to Asgard and Loki’s brief reign came to an end. For a short time anyway. Loki always finds a way back, as we now know.
Thor: The Dark World (2013)
After the destruction of Bifrost in Thor, the Nine Kingdoms fell into chaos. Thor and his Asgardian warrior friends quelled insurgencies and invasions on various worlds during this time. Sif fought the Marauder space pirates on the planet Vaneheim at the start of The dark world.
Sif led the battle until Thor arrived, and actually saved his bacon from a missile launch from one of the pirates. She then helped defend Asgard from the second Dark Elf invasion and even freed Loki to better help his brother. True, she threatened to kill him if he betrayed Thor. The last time we saw Sif in the movies, she and Volstagg delivered the Aether (aka the Reality Stone) to the collector. This event bore fruit in guardians of the galaxy and Avengers: Infinity War.
Agents of SHIELD (2014-2015)
Sif has become one of the few MCU characters on the big screen to appear on Agents of SHIELD. She first appeared in the episode “Yes Men” of the first season, where she came to Midgard to find an Asgardian fugitive named Lorelei. (Midgard is Earth, don’t you know.) The two shared a long rivalry, which is why Sif was tasked with returning her to Asgardian Prison. Lorelei initially escaped during the escape from prison to Thor: The Dark World.
In the season two episode “Who You Really Are”, Sif eventually lost her memory when she was attacked by the Kree warrior Vin-Tak. By the end of the episode, her memories were restored and she returned to Asgard. Of course, it is not clear whether Agents of SHIELD. is even canon in the MCU. Kevin Feige and Marvel Studios remain uncertain about this. So maybe it’s a Sif variant? Our first Asgardian variation before Loki, perhaps.
Until episode four of Loki, that was the last time we saw Sif on screen. Scheduling conflicts with his series Blind spot prevented Jaimie Alexander from appearing in Thor: Ragnarok. And that’s probably for the best, as she would likely have died at the hands of Hela in the movie, along with the Warriors Three. They didn’t mention her name in the movie, and Kevin Feige has said in interviews that “Loki probably banned her” before the events of Ragnarok. Loki probably thought that Sif would see through his Odin disguise before anyone else did. If anyone found out their true identity in Asgard, it would probably be Lady Sif.
However, she is about to come back in Thor: Love and Thunder in 2022. And then we’ll probably find out what this amazing warrior was doing all this time.
