Grayven is the third son of
Darkseid, born of an unknown mother and apparently without his father's knowledge, younger brother to
Kalibak and
Orion. Grayven leads a campaign of destruction against the cosmos, destroying planets. He leads a campaign against the
Darkstars, a galactic police force, killing many of their number. His campaign comes to an end on the planet
Rann. He desires a zeta beam device, a product of Rannian science that provides instantaneous transportation on a grand scale. He intends to zeta beam his forces onto
Apokolips, announce his presence to his father, and conquer the planet. While the Darkstars engage Grayven's army, Green Lantern
Kyle Rayner battles Grayven himself. Assisted by
John Stewart, Kyle tricks Grayven into using the Zeta Beam, causing him to be teleported off Rann and into Earth's core. Lacking their leader, Grayven's forces retreat. Grayven is resurrected following
The New 52 and
DC Rebirth relaunches. ==Powers and abilities==
