Chay-Ara was an Egyptian princess, married to the Egyptian prince Khufu. They found a crashed shipped which gave them their powers. But they were cursed by Hath-Set to die and then reincarnate, over, and over, always dying when reaching the peak of their love. In the 1940s, Chay-Ara was reincarnated as Shiera Sanders while Prince Khufu was reincarnated as Carter Hall who was also the winged wonder, Hawkman. Still connected to each other, Carter and Shiera formed a romantic relationship. While on the trail of criminals, Hawkman formulated a plan to capture them. He was able to contact Shiera to aid him in his plan.
The Silver Age version of Hawkwoman was Shayera Hol, a law enforcement officer from the planet Thanagar and wife of Katar Hol, the Silver Age Hawkman. She originally operated under the codename Hawkgirl, and was a member of the Justice League of America. She was born on Thanagar, which had a scientifically advanced civilization in which crime was virtually unknown. As an adolescent, Shayera joined the Thanagarian police force and was assigned to assist the force's most decorated officer, Katar Hol, in capturing the Rainbow Robbers. At first, Katar was furious at being assigned an inexperienced young woman as a partner, but he nevertheless became strongly attracted to her.
Ten years later, the couple was sent to Earth in pursuit of the criminal Byth Rok. Upon reaching Earth, they were befriended by Midway City police commissioner George Emmett, who established cover identities for them as Carter and Shiera Hall. After capturing Byth and bringing him back to their planet, Katar and Shayera chose to return to study Earth's crimefighting methods, and they fought against evil as the superheroes Hawkman and Hawkgirl.
As Shiera, she first worked as Carter's secretary, but later became co-director of the Midway City Museum.
Later, Thanagar had established itself as a military dictatorship bent on conquering other planets. Hawkman and Hawkwoman thwarted Thanagarian plans to invade Earth, destroying their own starship in the process. Hawkman and Hawkwoman remain on Earth, regarded as traitors by everyone on Thanagar. She helped her husband come to terms with the deaths they caused during the battle. Eventually, she changed her codename to Hawkwoman.
: Shares a last name with the newest incarnation of herself.
: Both Shea and Shayera have worked on and off in museums.
☥ CENTER OF THE UNIVERSE
: Both women were the center of their father's universes (as per Hawkworld).
: While Shea doesn't go and bust heads as directly as her counterpart, they both share a short fuse with the gut reaction to most problems being 'hit it' and when that doesn't work -- 'hit it harder.'
: Where Shayera has incredibly strong ties to the Egyptian people, Shea has found they're her favorite period in time, so much so as she's got a small gold ankh tattooed on the top inside corner where her shoulder and neck meet on the right side.
☥ MARTIAL ARTS
: Both women trained and trained more in various types of the martial arts.
: Attempted work in law enforcement and then left for security and bouncer work was used to mirror Shayera's time with the Wingmen and in the Thanagarian army.
Reincarnation; The Nth metal knife which murdered Hawkgirl in her original incarnation as Chay-Ara had an unusual effect upon her soul and that of her lover Khufu (Hawkman). The pair are locked in a seemingly endless cycle of death and rebirth throughout the centuries. While not a superhuman power per se, this propensity for reincarnation has allowed Hawkgirl to cheat death and return to active duty in her current incarnation.
Wings; They do exactly what you think wings would do.
