Seeking to replicate the success of Wonder Woman's creation, Zeus took the heart of the Hawai'ian god Kane Milohai and combined it with divine fire of his creation and the soul of an ancient hero to create Achilles, Warkiller and leader of his army of resurrected Greek heroes. He was placed by Zeus in the role of King of Themyscira, and turned to Alkyone to help him rule, making her his Queen in a purely political wedding. This arrangement was short-lived, as Alkyone usurped his role as part of a plot to both kill Diana and return Hippolyta to the throne. Realizing he could not let such an act stand, he freed Diana and joined her in a coup against his own Queen.
Although initially set against Wonder Woman, he had great respect for her and sought to work alongside her when possible.
