Sif (character)

Created by Stan Lee and Jack Kirby, Sif first appeared in Journey into Mystery #102 (March 1964). As a supporting character of Thor, she was featured predominantly in the pages of The Mighty Thor, beginning with issue #136 (January 1967).{{cite book |last1=Brevoort |first1=Tom |last2=DeFalco |first2=Tom |last3=Manning |first3=Matthew K. |last4=Sanderson |first4=Peter |last5=Wiacek |first5=Win |title=Marvel Year By Year: A Visual History |date=2017 |publisher=DK Publishing |isbn=978-1465455505 |page=120}} The character went on to make guest appearances in several series including The Avengers, Fantastic Four, The New Mutants, Silver Surfer and Thunderstrike.

In June 2010, Sif starred in a self-titled one-shot by writer Kelly Sue DeConnick and artist Ryan Stegman. The issue deals with the aftermath of Loki having taken control of her body and her consciousness being forced into the frame of a dying elderly woman. DeConnick said, "Well, this is pretty much the story of how she deals with that. She was a bit cowed at first and, for a woman as fierce and proud as Sif, that's insult added to injury. This is the story of how she comes to own that fury and rises to her full stature once again."{{cite web |url=http://marvel.com/news/story/11465/sifs_revenge |title=Sif's Revenge |last=Dietsch |first=TJ |date=25 February 2010 |publisher=Marvel.com |access-date=6 December 2012}}

Beginning with issue #646 (November 2012), Journey into Mystery by Kathryn Immonen and Valerio Schiti shifted focus from Loki to Sif. Editor Lauren Sankovitch said, "We had it Loki-centric... going forward with #646 we wanted to mix it up a little bit. Sif's been in the thick of it, she's a born warrior, she's got a lot of fight and verve and fire to her! We talked at length about what this story could be and what her story could be, and it all came down to ... one single question: what does she want? I think Sif, above all, wants to be a better warrior."{{cite web |last=Campbell |first=Josie |date=14 August 2012 |title=Immonen Leads Sif on a 'Journey into Mystery' |url=http://www.comicbookresources.com/?page=article&id=40445 |website=Comic Book Resources |access-date=14 August 2012}} The series was cancelled in August 2013 with issue #655. About the cancellation, Immonen said

We are done with 655. But seeing as we were basically cooked right out of the gate, I'm going to call hanging in for nearly a year a success. To be truthful, the real challenge that we inherited with this book was living up to the beautiful work that Kieron [Gillen] et al. had done previously and the amazing reader energy that had been generated. If all that had happened with our ten issues was to extend the influence of the astonishing Valerio Schiti, that would have been enough. As it is, I'm so proud of what Valerio, Jordie [Bellaire], Clayton [Cowles], Pepe and I put on the page under Lauren [Sankovitch] and Jake's fearless leadership. I'm also thrilled to have been able to write Sif as a fierce warrior and a lovable dork. I hope she finds a new home somewhere with a lot of things to say and a lot of things to kill.{{cite web |url=http://www.ign.com/articles/2013/06/14/marvel-cancels-journey-into-mystery |title=Marvel Cancels Journey into Mystery |last=Schedeen |first=Jesse |date=14 June 2013 |website=IGN |access-date=22 August 2013}}

Sif, Heimdall's sister,Thor: Son of Asgard #3 (June 2004). Marvel Comics. has been Thor and Balder's constant companion since childhood.Thor: Son of Asgard #1 (May 2004). Marvel Comics. Like most Asgardians, Sif was born with golden hair. Hers was turned black after Loki cut it and replaced it with enchanted hair made by dwarves.Thor: Son of Asgard #8 (Nov. 2004). Marvel Comics. At an early age she showed great prowess as a warrior and was considered the best female warrior in all of Asgard, matched only by Brunnhilde. At one point a giant gave her to the death goddess Hela in exchange for immortality, but Thor saved her by offering himself in her place. Hela was so impressed that she let them both go.Thor: Son of Asgard #10–12 (Jan. – Mar. 2005). Marvel Comics.

Sif was originally said to be Balder's sister rather than Heimdall's in her first appearance.Journey into Mystery #102. Marvel Comics.

Sif and Thor are separated when his father Odin banishes Thor from Asgard and Thor begins a life as a superhero on Earth. Many years later Thor becomes romantically involved with Jane Foster. Thor brings Jane to Asgard to be wed and she is granted immortality but fails a final test. Odin sends her back to Earth, stripped of her newly acquired powers and without memories of the event. Odin then arranges an encounter with Sif while Thor is battling the monstrous super-strong Unknown and the two fall in love again.Thor #136 (Jan. 1967). Marvel Comics.

Later, the alien warrior Beta Ray Bill comes to the defense of Earth during a war with Surtur and his demon army. In the midst of battle Sif and Bill find themselves attracted to each other. Meanwhile, Lorelei has given Thor an elixir that causes him to fall in love with her, and he is so blinded by the spell that he strikes Sif in anger. When the war is over, Sif and Bill spend some time on Earth exploring their mutual attraction before returning to Asgard. Sif eventually returns and finally comes to forgive Thor after she realizes that Lorelei was to blame for his brutality.Thor #349–359 (Nov. 1984–Sept. 1985). Marvel Comics. However, she clarifies to Balder that her love for Bill is purely platonic."Thor" #442 (Jan. 1992). Marvel Comics.

She also develops a romantic relationship with another mortal to wield Thor's power, Eric Masterson. Despite this, Sif risks her life to travel to the realm of Mephisto to free what seems to be the soul of Thor from a mystical bag, pledging her loyalty to the demonic entity. She is manipulated into a new costume change and is sent to face down Eric and Balder in battle, who had willingly followed her, worried for the success of her mission. Eric and Sif eventually part realms as friends, but he leaves her with a favored leather jacket.Thor #450–455 (Aug.–Dec. 1992). Marvel Comics.

When Thor assumes the throne of Asgard following Odin's death, he becomes torn between his duties as king and his desire to keep mortals from harm.

Though his intentions are noble, a nightmarish future follows as Thor's reign on Earth becomes tyrannical.Thor vol. 2 #41–74 (Nov. 2001–Apr. 2004). Marvel Comics.

Sif shares powers common among all Asgardians, with her dense physiology granting superhuman strength greater than the average Asgardian female and on par with the average Asgardian male, limited invulnerability, as well as advanced stamina, speed, agility, and reflexes. Sif is also extremely long lived and maintains her youth and vitality through the consumption of golden apples. She is also highly skilled in hand to hand combat and proficient in the use of cold weapons, favoring a sword and shield in battle. She is often said to be the best female fighter in Asgard, on par with Valkyrie.Thor: Son of Asgard #8. Marvel Comics.

In early appearances, Sif also possessed the innate ability to teleport herself and others from Earth to Asgard. At some point, Sif began relying on her enchanted sword, which could "cleave" open gateways to other destinations besides Earth and Asgard through a complex array of swinging motions.Thor #234 (Apr. 1975). Marvel Comics. However, during The Reigning, after Thor failed to truly resurrect a young girl, Sif was once again able to teleport herself and Thor away without the use of her sword.{{Volume needed|c=y|date=November 2010}} Sif and Balder relied on the Norn Stones to teleport when they were looking for Thor.
