Lady Sif and her brother, Heimdall, were born of the second-generation gods of Asgard, although their parentage has yet to be revealed. During their childhood, Sif was a constant companion of Thor, Balder, and Loki. Upon reaching her adolescence, Sif and Thor seemed to develop a romantic relationship, which even Odin approved of, deeming her worthy to one day become the wife of her childhood friend. However, Loki, who grew jealous of Sif's affection towards Thor, decided to play a foul prank on the Asgardian when he cut off the golden hair for which she was renowned. This misdeed was quickly discovered when Sif awoke and Thor forced Loki to restore her hair. Loki attempted to create a bargain with the trolls Brokk and Eitri, who made the hair out of pure gold. Unfortunately, Loki stole the newly created hair before it was able to be treated with a special potion and upon placing the hair on Sif's head, it grew darker by the minute before finally turning as black as night. Sif continued to grieve over the loss of her golden hair until her parents finally tired of her vanity and sent her to learn the way of the warriors by having her train to become a shieldmaiden.
During her time in training, Sif still accompanied Thor and Loki on adventures, although she never forgave Loki for his cruel prank. Sif often attempted to get romantically closer to Thor and even developed a brief rivalry with Amora the Enchantress and Brunhilde, the future Valkyrie, when she was tricked by the former and Loki into stealing the Mirror of Mycha from Karnilla's palace. Amora and Loki both told Sif that she would be able to use the mirror to permanently capture Thor's affections, but Amora used the mirror on Thor before Sif had the opportunity. Brunhilde eventually came to Sif's aid when the two put aside their differences to work together and release Thor from the mirror's enchantment. Although Thor was disappointed in Sif's initial attempts to use the mirror, the two quickly made up and rekindled their budding relationship. -ComicVine
