Ocean Master is a supervillain appearing in American comic books published by DC Comics. The character was created by Bob Haney and Nick Cardy and debuted in Aquaman #29 (September 1966). One of Aquaman's most recognized adversaries who is characterized to often plot to usurp his position as the ruling monarch of Atlantis, the character has been subjected to revisions over the years.
Originally, the character was Orm Curry Marius, Aquaman's wayward, human half-brother envious of his sibling's superhuman powers and status as a hero. Becoming an international marine criminal, he takes the name "Orm Marius" and "Ocean Master". Following Crisis on Infinite Earths, the character is retroactively depicted as half homo magi, of Inuit origin, and related to Aquaman through Atlan. This sorcerous and royal origin story heightens the dramatic stakes of his plots to usurp the throne of Atantis.
Following his revision in the New 52, he is definitively established as Orm Marius, a full-blooded Atlantean royal whose parents includes Queen Atlanna (also Aquaman's mother), King Orvax Marius (making him half-brother of Tula), and is a desendant of Atlan and Arion. This version holds xenophobic views towards humans and a desire to punish them for their role in marine pollution. Although he similar conspires to with the throne of Atlantis from Arthur, Orm is cast as a more benevolent but traditionalist ruler who is exiled by Aquaman, believing him a tyrant follow Orm's attack on the United States. While embittered by the ordeal and acting as an antagonist, he is also a reluctant ally and anti-hero.
Ocean Master has been adapted from the comics into various forms of media.The character appeared in the DC Extended Universe films Aquaman (2018) and Aquaman and the Lost Kingdom (2023), portrayed by Patrick Wilson. Richard Green, Wallace Langham, Dana Snyder, and Sam Witwer have provided the character's voice in animation.
Publication history Ocean Master first appeared in Aquaman #29 (September 1966), created by Bob Haney and Nick Cardy during the Silver Age of Comics Books. A seemingly one-off story, the issue establishes the brotherly relationship between the characters. Originally in the story, the character was first established as a human pirate similar to Black Manta whose relation to Aquaman was shared.
The character would later make a major reappearance in the second Aquaman series, written by Neil Ponzer in 1987, following the reboot of the DC Universe through Crisis on Infinite Earths. The new story changes the nature of the character's powers and ties them to a new history and world established by the previous Arion, Lord of Atlantis title. The limited series also established his original origin in line with the Silver Age's version as being the wayward and ignored son of Tom Curry and Mary O'Sullivan.
Later in 1996, the character's background and origins were altered in Peter David's Aquaman: Time and Tide. This version depicts him as an indigenous Iñupiat man from Alaska who is Aquaman's half-brother through their shared father, Atlan.
In 2011, DC Comics would relaunch all of its monthly titles and reboot the DC Universe continuity. Among the changes included Orm's new origin, cast as a full-blooded Atlantean, whose shared parentage with Aquaman is through Atlanna, and having similar physical powers to Aquaman and abilities derived from artifacts. The character's first major appearance after the reboot is in the Throne of Atlantis storyline, which depicted the beginning of the antagonistic relationship between Ocean Master and Aquaman. Later stories would define Ocean Master and Aquaman's heritage further: the 2013 Death of a King storyline indirectly establishes Atlan (previously the father of Ocean Master) as their ancestral relative, and the 2019 Drowned Earth storyline establishing Arion as their ancient ancestor.
Fictional character biography Pre-Crisis Orm Curry was Aquaman's full-human half-brother, the son of Thomas Curry (Aquaman's father) and a woman named Mary O'Sullivan. He grew up under the shadow of his heroic half-brother and resented the fact that he had none of Aquaman's powers. He was already a petty criminal when he was stricken with amnesia, forgot his former life, and disappearing.
Several years later, the self-named Orm Marius reappeared as the Ocean Master, a high-tech pirate who initially attacked ships but quickly moved on to causing natural disasters to hold the world at ransom. Aquaman and Aqualad were captured by Ocean Master but managed to escape. Aquaman, having seen behind Ocean Master's mask and realizing that he was his half-brother Orm, was then unable to fight Ocean Master, although he did stop his plan.
Post-Crisis on Infinite Earths After the events of the Crisis on Infinite Earths storyline, significant changes were introduced to the Ocean Master character. In this revised version, Ocean Master is portrayed as a hybrid of half homo magi (ancient Atlantean) and human descent with Inuit heritage. This unique ancestry bestows upon him inherent mystical potential, expanding upon previous portrayals of the character that showcased his magical abilities. Furthermore, this revised backstory establishes a biological connection between Ocean Master and Aquaman, as they are revealed to be half-brothers through their shared parent, Atlan.David, P. (1996). In Aquaman: Time and Tide. DC Comics.
Aquaman: Time and Tide Ocean Master appears as the main antagonist in the storyline "Aquaman: Time and Tide", where Aquaman chronicles his life experiences. While writing the book and reflecting on the past, Aquaman discovers a connection between Ocean Master's background and his own, leading him to realize that Ocean Master is his secret half-brother, as foretold by an ancient prophecy involving his biological father.
In the earliest chronologically depicted story from Ocean Master's youth, Aquaman encounters a young Inupiat woman whom he rescues from a polar bear attack. Among her family members is Orm Marius, an Inupiat who is considered an outcast by his tradition-bound family due to his nonconformist beliefs and his perception of their primitiveness. Orm believes that his mother holds a deep-seated hatred towards him. Although she claims that he is the son of an "underwater wizard," Orm dismisses this notion. Orm encounters a young Arthur Curry (Aquaman), whom he dislikes because Arthur has gained favor with the same family that rejected him. In a fit of jealousy, Orm attacks Kako, the woman, after discovering her intimate encounter with Arthur. While Kako survives the attack, she cannot recall the identity of her assailant. Arthur is cast out from the family home when they discover his confrontation with Nuliajuk, a revered deity, believing that Arthur's actions would bring a curse upon them for taking him in.
In another story set some time after the encounter with the Inupiat tribe, Aquaman encounters Orm once again, this time as "Ocean Master." Orm attempts to challenge and assassinate Aquaman but is easily defeated and spared by Arthur, who feels both pity for Orm's methods and an inability to deliver a more severe punishment for unknown reasons. Later, Atlantis falls under attack from Ocean Master's forces, and Aquaman and Aqualad intercept the assault but fall into a trap. While Ocean Master expresses his deep-seated hatred for Aquaman, he also reveals himself as the assailant who attacked Kako. In a moment of rage, Aquaman frees himself but is then distracted by Mera's attack, causing Ocean Master, Mera, and Aqualad to escape during the ensuing chaos triggered by the ship's self-destruct sequence.
JLA: Our Worlds At War Ocean Master clashes with the JLA again when he attempts to claim the remains of Atlantis following Aquaman's apparent death in the 2001 storyline "Our Worlds at War".
Aquaman: To Serve and Protect Ocean Master would later appear as one of the antagonists in the "To Serve and Protect" storyline in the sixth Aquaman title, having used his mystical talents to alter reality so that he was Aquaman and Orin was Ocean Master, using a spell with the bones of Aquaman's lost hand as a focus. As Aquaman, Orm holds Sub Diego under his evil rule, restricting the city's growth by claiming that the surface world had been destroyed by the attack that sunk the city.Aquaman (vol. 6) #26 (March 2005). DC Comics. However, Arthur is able to defeat his brother's plot, thanks to Doctor Geist, the scientist who had turned Sub Diego's population into water-breathers. Geist had studied Aquaman extensively and was unaffected by the spell as Orm did not know he even existed, Arthur having faked Geist's death so that he could work on reversing what he had done. Geist is able to provide Arthur with enough details of the real world to find the source of Orm's power and destroy it.Aquaman (vol. 6) #27 (April 2005). DC Comics.
Infinite Crisis In the 2005–2006 storyline "Infinite Crisis", Ocean Master becomes a member of the Secret Society of Super Villains.
Final Crisis In the 2008–2009 storyline "Final Crisis", Ocean Master is placed on the new Society's inner circle by Libra.
Aquaman: Sword of Atlantis In the series Aquaman: Sword of Atlantis, Ocean Master enslaves the Atlanteans who survived the Spectre's destruction of Atlantis, and is using them to mine industrial materials for the surface world.
The New 52 In The New 52, DC Comics' relaunch of all of its monthly titles and the rebooting of the DC Universe continuity, Ocean Master's origins are once again revised. Unlike previous depictions of the character, Orm is cast as a full-blooded Atlantean and is initially characterized as having genuinely, brotherly love for Arthur and holds disdain towards "surface dwellers" for their acts that have polluted the oceans for thousands of years and prefers not sharing the Earth with them. Despite inclinations to attack the "surface dwellers" for perceived crimes towards the ocean, Orm instead rules for the benefit of his people and adheres to a code of conduct.DC Comics Encyclopedia: All-New Edition
Origin Orm was born as the second son of Queen Atlanna, making him the younger half-brother of Arthur Curry. After Atlanna has Arthur with a human male, Tom Curry, she gives up the child and allows him to raise their son. Atlanna is forced to return to Atlantis and to marry a member of her royal guard, with Orm the result of the union. As a child, Orm was told stories of terrors of humans ("surface dwellers") and how he had a half-brother on the surface. Saddened, he begged for the Atlantean guard to rescue him but was denied, inspiring him to take the throne to one day "rescue" his brother.
Twelve years later, Orm inherited the throne after mysterious circumstances after the deaths of his father and mother days apart, the former assumed to be killed by his enemies and the latter accused of being killed by Orm himself by royal advisor Nuidis Vulko. Failing to produce evidence, Vulko escapes and plots to overthrow Orm by placing Arthur on the throne. When Vulko is confronted by Arthur (who is searching for Atlantis), he explains his brother's origins and tells him that Arthur is the rightful heir of Atlantis's throne, and therefore, must overthrow Orm, whom he claims to be corrupt ruler.Aquaman (vol. 7) #0 (September 2012). DC Comics.
When the brothers meet, Aquaman assumes the throne. However, he abdicates it to Orm once more to live out his life as Aquaman under the promise that Orm does not attack the surface.
