Hath-Set is a DC Comics supervillain created by Gardner Fox and Dennis Neville. The character is a recurring nemesis of Hawkman and Hawkgirl.
Hath-Set, a cruel Egyptian priest, first appeared in Flash Comics (issue #1, January 1940). He leads a rebellion and captures and murders Prince Khufu and Princess Chay-Ara. He kills them with a cursed dagger which has been forged from Nth Metal. This results in a cycle where all three are reincarnated together. In many different incarnations over the centuries, Hath-Set murders the Prince and Princess.
In the World War II era, Hath-Set is reincarnated as the evil Doctor Anton Hastor. Hawkman (the Prince) and Hawkgirl (the Princess) are reunited while facing Hastor. Hastor (Hath-Set) is Hawkman's first foe. In 1941, Hastor kidnaps some prominent scientists. He pools their talents and knowledge to build a flying mechanical eye airship, with weaponry capable of leveling whole cities. His plans for world conquest are foiled by Hawkman and the All-Star Squadron. However, Hastor kidnaps Hawkgirl and then is killed by Hawkman with a crossbow.
