Nathan King, a young man burdened by mental instability and chosen as the earthly avatar of Khonsu, the Egyptian god of the moon, finds himself crossing paths with Superman. Though their approaches to justice are vastly different-Nathan's methods shaped by the chaotic whispers of his patron god and Superman's by his unwavering sense of honor and compassion-they recognize a shared purpose. Uniting their strengths, the two heroes agree to set aside their differences, joining forces to defend Metropolis against the encroaching darkness threatening the city.
