Grayven is a fictional deity and supervillain published by DC Comics. He first appeared in Green Lantern v3 #74, (June 1996), and was created by Ron Marz and Darryl Banks.

Grayven is the third son of Darkseid, born of an unknown mother, younger brother to Kalibak and Orion. 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 remaining Darkstars engaged Gravyen's army, Green Lantern Kyle Rayner faces off against the man himself. Assisted by former Green Lantern and current Darkstar John Stewart, who suffers serious injuries in the fight, Kyle tricks Grayven into a Zeta Beam device, where he is teleported off Rann. Lacking their leader, Grayven's forces retreated.

Unknown to Stewart, Rayner had inadvertently teleported Grayven deep within Earth's core. He eventually digs himself out, and seeks Rayner in New York City, who is seemingly able to overpower Grayven. Fearing defeat at the Green Lantern's hands, Grayven used an experimental teleporter, freeing himself, and in the process, sending Rayner into the 30th century.
