| ||We will rebuild, and we will thrive.|
Around the turn of the 13th century, Kalibak and the rest of Darkseid’s forces attempted to conquer Earth but were faced with resistance from Vandal Savage, who was using the name Genghis Khan and his army. He and his father's army decimated Savage’s army but the latter wasn't defeated. Standing by, Kalibak watched as Darkseid brokered a deal with Savage and a partnership was formed to conquer the Galaxy, however once this goal was accomplished, Earth and Apokolips would engage in a final battle for sole domination of the universe.
Dispatched by his father to aid Savage in battling an unknown armada, Kalibak contacted Savage and they shared tense words before Kalibak annihilated the entire armada by sacrificing one meta-human.
