History: Sif is a warrior goddess of Asgard and the sister of Heimdall, guardian of the Rainbow Bridge. Although her modern parentage is unrevealed, it is known that she was once the daughter of Odin, ruler of the Asgardian Gods, and the sea-goddess, Alti, daughter of the sea-giant, Aegir.  She was also once the wife of Thor and mother to his daughter, Lora and Thrud. However, these are almost certainly aspects of the Sif who existed in a earlier incarnation of Asgard. Except for her memory of Heimdall being her brother, the modern Sif has none of these memories and her children were most likely killed in the demise of this earlier Asgard. Nevertheless, the modern Sif does recall being in love with Thor and much of her modern life is starting to resemble her previous existence. As a child, she had golden hair and was an occasional playmate of Thor, son of Odin, and Thorís adopted brother, Loki. 

While Thor and Sif were still adolescents, they fell in love with each other. Determined to ruin his hated brotherís happiness by ending the relationship between Thor and Sif, Loki cut off all of Sifís golden hair while she slept. Realizing that Loki must have been responsible, Thor angrily confronted Loki and demanded that he restore Sifís hair. Loki sought out the dwarves Brokk and Eitri and asked that they create new hair through their arts. However, Loki was either unable or unwilling to pay the dwarves gold for this work. The decided that for the ďprice of naughtĒ they would create ďstrands of naught.Ē They magically created long strands of hair from the blackness of night. Once set upon Sifís head, the hair magically took root and began to grow. Thor thought Sif was even more beautiful with the black hair than she had been before, and thus, Lokiís plan to ruin their romance failed.  

Eventually, Thor and Sif parted when Sif began her training to be a warrior in earnest. Odin, Lord of Asgard, had long deemed Sif to be a fitting mate for his son Thor. Just after Thorís relatively brief relationship with the mortal woman Jane Foster came to an end, Odin, hoping to turn Thorís affections into another different direction, arranged for him to meet Sif once more. Sif was now very well accepted in the ways of a warrior. Soon after meeting Sif again, Thor and Sif became lovers and companions, as well as allies in several battles. Eventually, they decided to marry.

However, Thorís attachment to Earth frequently came between them. Sif much preferred Asgard to the mundane modern world of mortals, and, after attempting to adjust to life on more than one occasion, returned to live in Asgard without Thor. Once, when Thorís mortal paramour Jane Foster was dying, Sif lent her life force to revive the woman, merging psychically with her in the process. She did this apparently to understand Thorís affection for this mortal. Jane Foster was separated from Sif shortly thereafter and sent to the limbo-realm of the Runestaff of the Possessor. Sif and Thor have since rescued Foster. Sif and Thor both aided the alien champion Beta Ray Bill in defending his people against the onslaught of the demonic armies of Surtur. Sif and Beta Ray Bill found themselves increasingly drawn to each other emotionally. Sifís relationship with Thor was greatly worsened when Thor, who was forced by an enchantment to fall in love with the goddess Lorelei, struck Sif in anger. Sif even attempted to leave Asgard and accompany Beta Ray Bill back to his people.

However, Sif came to realize how deeply sorry Thor, who had been freed by Loreleiís enchantment, was for having striking her. Moreover, Sif was greatly impressed by Thorís heroism into descending down into the realm of the goddess of the dead, Hela, to rescue the souls of several mortals taken from earth. As a result, Sif finally accepted Thorís role as both guardian of both Asgard and Earth, and decided to stay behind in Asgard while Beta Ray Bill returned to his people. Sif and Thor once more became linked by strong bonds of love and affection.   

Following the invasion of Asgard by Seth, the Egyptian god of misfortune, Sif was romantically pursued by Leir, the Celtic God of storm who had lead the Tuatha Danaan to rally with the Asgardians against Sif. In order to spur jealousy from Thor and encourage him to a more devoted relationship, she sent Leir on a search for Thor on earth, but as Thor failed to react as she expected, Sif instead challenged Leir to see if he was worthy of her and defeated him. As Sif attacked the Asgardians through Yggdrasil, the tree of destiny among the Asgardians, Sif and all the Asgardians were hidden on earth as mortals by Odin to conceal them from Seth. Sif became a policewoman in New York City named Erica Velez, but even as a mortal, the Asgardians were able to defeat Seth.

Odin eventually died battling Surtur and Thor replaced him as Lord of Asgard. Loki created a revised version of Ragnarok to attack Asgard leading the forces of the Underworld and Sif fell in battle fighting Lokiís armies. Thor meanwhile discovered that the repeating cycles of Ragnarok were being controlled by shadowy beings called Those Who Sit Above In Shadow and permitted Ragnarok to occur in order to stop these recurring cycles of Ragnarok from occurring. Sometime later, the Odin-Force in the form of a small child began the process of restoring Asgard to its former grandeur with Sif and the other Asgardians restored to life.

Height: 6'2"
Weight: 425 lbs.
Eyes: Blue
Hair: Black (formerly Golden Blonde)

Strength Level: Sif possesses superhuman strength enabling her to lift (press) 40 tons under optimal conditions.

Known Superhuman Powers: Sif possesses the conventional physical attributes of the Asgardian gods. Like all Asgardians, she is exceptionally long lived, but she is not immortal like the Olympian gods. She has not aged since reaching adulthood and cannot die by any conventional means. She is immune to all Earthly diseases and is resistant to conventional injury. If she were somehow wounded, her godly life force would enable her to recover with superhuman speed. It would take an injury of such magnitude that it dispersed a major portion of her bodily molecules to cause her a physical death. Even then, it might be possible for a god of significant power, such as Odin or for a number of Asgardian gods of equal power working together to revive her. Sif also possesses superhuman strength and her Asgardian metabolism provides her with far greater than human endurance in all physical activities. (Asgardian flesh and bone is about three times as dense as similar human tissue, contributing to the Asgardians' superhuman strength and weight.)
Sif's Asgardian metabolism gives her far greater than human endurance during all physical activities. She has greater strength and stamina than any other Asgardian with the possible exception of Brynhilda.

Sif has extensive training in unarmed combat as well as swordsmanship.  Her fighting ability is only surpassed among known Asgardian women by Brynhilda.

Sif wields a special sword enchanted by Odin to enable her to "cleave" passageways between dimensions (primarily Asgard and Earth) by a special pattern of swinging motions. It is unknown if she can travel to any other worlds.
