Shiera Sanders, the Golden Age Hawkgirl, was a frequent companion of the Golden Age Hawkman, Carter Hall. She was also member of the All-Star Squadron and a close associate of the Justice Society of America.
Archaeologist Carter Hall has a dream that he is an ancient Egyptian prince, Khufu, who has a lover, Princess Chay-Ara. The next day, Carter meets a woman named Shiera who looks exactly like the woman in his dream. Carter dons the identity of Hawkman and Shiera becomes Carter's girlfriend. Shiera dons a spare set of Nth metal wings developed by Hawkman, and masquerades as Hawkman in order to trick some criminals. Shiera continues to wear the costume and wings in later stories, eventually adopting the identity of Hawkgirl.
The Golden Age Hawkgirl was Shiera Sanders (or Saunders), the reincarnation of the Egyptian princess Chay-Ara, and partner of Carter Hall, the Golden Age Hawkman. Centuries ago, Chay-Ara and her lover Prince Khufu were killed by Hath-Set with a knife forged from an alien substance called nth metal. The properties of the metal and the strength of the duo's love created a bond between them, causing them to be reborn multiple times throughout the centuries.
In the early 20th century, Chay-Ara was reborn as Shiera Sanders. She was kidnapped by Dr. Anton Hastor (reincarnation of Hath-Set) but subsequently rescued by Hawkman (her reborn lover Khufu). Shiera became the hero's frequent ally and love interest. Eventually, she was granted a costume of her own and a belt of gravity-defying nth metal and joined him at his side as Hawkgirl.
The Hawks were members of the All-Star Squadron, and while Hawkman was a member of the Justice Society of America, Hawkgirl was not, only assisting the group on occasion. Eventually, Carter and Shiera married and had one son, Hector Hall.
Shiera died when she was merged with Carter and Katar Hol to form a new Hawkman version, a "hawk god" creature, during the events of Zero Hour.
