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.
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.
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.
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.
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.
Aquaman suspects Orm to be the Atlantean who hired Black Manta to steal Aquaman's scepter, which is an Atlantean relic of great power that was taken from the Dead King's tomb. When the Atlantean retrieves the relic, Aquaman believes Orm is in the Atlantean ship and demands that he reveal himself, but the Atlantean ship escapes. Later, Orm is visited by Aquaman to ask if he took the scepter, but Orm says that he did not, saying that if he wanted the relic scepter he would ask Aquaman for it.
DC Universe (2017-)
Eventually, Ocean Master re-emerges with a new status quo; now depicted as a reformed super-villain having given up his former life to live on dry land with Erin and Tommy, he is conflicted between the safety of Atlantis and his envious-driven yearning to overthrow his rival and brother, Aquaman.
Orm returns in the miniseries Mera: Queen of Atlantis. At the start of the series, he is shown to be engaged to Erin and views Tommy as his son, having decided to leave Arthur to rule Atlantis and settle down with his new family. However, when he learns that his brother has been deposed by the usurper Courm Rath and is now presumed dead, Orm silently leaves Erin and Tommy in the middle of the night, feeling duty bound to reassert his claim to the throne. This brings him into conflict with Mera, whom the power brokers of Atlantis have selected to replace Rath, and his sister Tula, who is now a close ally of Arthur and Mera. Mera defeats Orm and has him imprisoned.
In the "Drowned Earth" crossover event, when all the inhabitants of Atlantis besides the two of them are transformed into monsters by tainted waters released by a trio of alien sea gods. He leads her to a hidden chamber where an ancient artifact called the Clarion which could repel the invasion is stored, but is himself transformed by the waters.
Orm appears in a one-shot special as part of the Year of the Villain crossover event. Following Drowned Earth, Orm hid as a beggar on the streets of the Ninth Tride, Atlantis' poorest district and closest to the sea floor. Still considered a wanted criminal by Mera's regime and unable to escape the city due to impenetrable guard patrols which he himself designed, Orm wandered the streets, bitter from the feeling that despite sacrificing everything for Atlantis, it neither needed nor wanted him. Orm would learn of a surface king by the name of Dagon who controlled a powerful ocean elemental through an amulet. Later that night, a mad beggar heard the same elemental and would make his escape with Orm following him, learning of a security flaw in Atlantis. Once free, he witnessed someone take the beggar and followed them to a rig where he encountered one of Aquaman's foes, the Marine Maruder, and learned of her new abilities of manipulating the bodies of marine life courtesy of Lex Luthor. He escapes and saves the beggar, who then leads him to where he hears the call of the ocean elemental from the story of King Dagon. Orm manages to find the ocean elemental from the stories after venturing in the deep ocean to the point even an Atlantean body struggled from the pressure. Introducing herself as Lernaea, she frees Orm from the deeper depths of the ocean. Orm would go back to slay the Marine Maruder for her transgressions against the Atlantean she abducted and fed her body to his newfound followers, christening them citizens of the "City of Dagon". King once more, he is visited by Lex Luthor and is offered the chance to gain power through him. Orm rejects his offer and frees the Lernaea, who chooses to freely follow Orm, before threatening Luthor to stay out of his oceans. Orm then visits Erin and relays the whole story to her, explaining his whereabouts since he last seen them. Due to his choices in choosing his life as Ocean Master and Atlantis over them, Erin breaks up with Orm though he relents that despite all matters, he considered Tommy his son and will approach him when he is older and give him the option of being his heir before leaving her. Now backed by Atlantean outcasts from the homeless population of the Ninth Tride and the Lernaea from loyalty, Orm officially christens himself king of Dagon.
Characterization
Personality and themes
While having been depicted as both a super-villain and more akin to an anti-hero, Ocean Master is typically characterized as a ruthless and blood-thirsty and a contrast to Aquaman, being less noble and charitable as well as envious of his brother. However, various stories following the New 52 vary his leadership; some stories showcased him as a militant but fair and benevolent ruler whose outlook as a tyrant was shaped by Vulko's manipulation, whom believed a young Orm conspired to kill his mother for the throne despite lacking evidence. Subsequent storylines would reveal his innocence and a temporary alteration of the mainstream timeline of showcased a possibility of Orm opting for him and Aquaman ruling as brothers-kings. Other stories would instead characterize him as manipulative and tyrannical in a position of power.
According to Geoff Johns, Johns opined that he does not view Orm (prior to being known as Ocean Master) as a malicious super-villain, characterizing him as someone doing what he believes is best for the Atlantean people and does not quite hate his brother, Arthur. Like many of his fellow people, he shares a bizarre perspective on the "surface world" and has a pride and culture different from the "surface". John's intent for the character included exploring the character in a different manner compared to traditional super-villains such as Sinestro or Black Hand. In an interview regarding his role as Ocean Master in Aquaman, Patrick Wilson stated that he does not view the character as a villain; while considering him a villain in comic book lore as a foil and antagonist, Wilson opined that he is "rooted" in an understandable dilemma of being angry at the pollution and destruction of the ocean. He further speaks upon the character's trait of being angry consistent throughout the character's existence and believes the character's actions of being irrational or reprehensible while believing the character to being justifiable in his anger.
Reputation
A formidable super-villain, Ocean Master is cited as one of Earth's most dangerous individuals and rated "Alpha-class" by the Justice League. This particular classification is shared by numerous other superpowered metahumans in the DC Universe, including Black Adam, Guy Gardner, and Mary Marvel.
Powers and abilities
Original version
As a non-metahuman pirate, he was an expert in tactics, nautical knowledge, and formidable hand-to-hand combat skills, allowing him to hold his own against most human opponents. Ocean Master frequently stolen utilized advanced technologies, such as his helmet and battle armor. The helmet featured gill functionality, enabling him to survive underwater for extended periods and endure the intense pressures of the ocean depths. He possessed other technologies such as harpoon guns, submarines, sonic weaponry, nets, and lasers. When retroactively revealed as a descendant of ancient Atlanteans, he possessed a hybrid nature that granted him mystical potential. Acquiring knowledge and capability with the mystic arts drawn from an era associated with one of the most influential mystics in Atlantean history, this granted him numerous magical abilities including superhuman strength, the capability to breathe underwater indefinitely, teleportation, illusion casting, and the power to summon magical creatures from the depths of the ocean to aid him.
His abilities were further augmented by his magical trident and allows him to discharge mystic energies. The full extent of its capabilities remains unknown. Additionally, the trident enables Ocean Master to breathe underwater indefinitely, similar to the function of his special helmet. Orm also once possessed the Zodiac Crystals, bolstering his magical abilities to a much higher degree.
Current version

Although he hasn't explicitly exhibited magical powers, references to select storylines in current continuity implies he possess powers similar to past depictions. Ocean Master is also as a highly skilled warrior, having honed his abilities at a young age and is regarded as a superior fighter compared to the average human with similar training. He also has a genius-level intellect with knowledge in fields including politics, military operation, medicine, and leadership, able to establish his own nation, command military forces, and is comparable to medical specialists in Atlantis.

He also has access to advanced technology.
Weaknesses
In his original version, Ocean Master experienced excruciating nerve pain when he separated himself from the magical trident given to him by Neron. The current version, due to his Atlantean biology, dehydrates at an accelerated rate compared to humans, gradually making him weaker when spending prolonged periods on the surface without regular hydration.
