He is the eldest son of Darkseid, half-brother of Orion and Grayven, and an enemy of Superman and the Justice League. Kalibak is the first-born son of Darkseid and Suli. His mother Suli is killed by Desaad, acting under orders from Kalibak's grandmother Queen Heggra. Kalibak becomes a legendary warrior, and often serves as Darkseid's second-in-command. After Darkseid breaks the pact of peace with New Genesis, the rival planet of Kalibak's home Apokolips, he aids his father in the resulting battles.
