The Golden Age Hawkgirl was Shiera Sanders Hall, 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 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. Some of her incarnations include:
* Lady Celia Penbrook, alive during 5th century Britain, and love of Silent Knight
* Cinnamon (also known as Kate Manser), an Old West gunslinger, and love of Nighthawk
* Sheila Carr, lady love of Pinkerton detective James Wright
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. Recent retcons seem to point to Hawkgirl being formally inducted into the JSA at some time, however. Eventually, Carter and Shiera married and had one son, Hector Hall, the previous Doctor Fate.
Through retcon Carter and Shiera also joined the Justice League of America in the late 1980s, serving as liaisons between that group and the Justice Society.
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, but was revived during the events of Blackest Night by the White Lantern ring.
