Ocean Master

Ocean Master is Aquaman's half-brother Orm, a surface-world man who resents his sibling's rule over Atlantis and turns to villainy to claim the throne he believes is rightfully his, wielding advanced technology and sorcery to wage war beneath the seas.

Born from the creative minds of Bob Haney and Neal Adams in The Brave and the Bold #82 (1969), Ocean Master is a Silver Age DC villain with the deep, dramatic flair that era did so well. Sharing pages with the likes of Aquaman, Green Lantern, and Bruce Wayne across titles like Aquaman and Justice League of America, this undersea antagonist has haunted DC's aquatic corners for over five decades. The sheer staying power — a presence stretching from 1969 all the way to 2025 — speaks to a character who resonates far beyond a single storyline or era. If you love the rich, mythic side of DC's oceanic world, Ocean Master is absolutely worth diving into.
