The Ocean Master is a supervillain published by DC Comics, and is the brother of Aquaman. He first appeared in Aquaman #29 (September 1966), and was created by Bob Haney and Nick Cardy.

Biography

Pre-Crisis
Orm Curry was Aquaman's fully human half-brother, the son of Tom 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, being fully human, and he was already a petty criminal when he was stricken with amnesia and forgot all about his former life, disappearing shortly afterwards.

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 in order to hold the world at ransom. Aquaman and Aqualad were captured by Ocean Master but managed to escape. Aquaman was then unable to fight Ocean Master after having seen behind the Ocean Master's mask and realizing that he was his half-brother Orm, although he did stop his plan.

In his subsequent appearances Ocean Master, believing Aquaman was afraid of him, had decided to overthrow Aquaman and usurp his throne. Unable to survive underwater, he made a special costume and helmet to help him breathe while in the ocean and clashed with Aquaman many times. Ocean Master regained his memory when Deadman took possession of his body and unlocked Orm's memories in Aquaman #50 (March–April 1970), but he continued to plot against his half-brother.


Post-Crisis
The Ocean Master's origins changed following Peter David's reinvention of Aquaman. He is still Aquaman's half-brother, but since Aquaman is no longer the son of Thomas Curry, Orm is now the son of Atlan the wizard (Aquaman's true father) and an Inupiat woman.

He first appeared in #3 of the miniseries Aquaman: Time and Tide (February 1994), in which Aquaman recorded the story of his life. This told how one of his early encounters with humans was when he rescued a girl named Kako from a polar bear. Her family were all traditionalists, except her cousin Orm, who had no time for the old ways. When Kako and Arthur began a sexual relationship Orm attacked her in a jealous rage. Although she survived, she did not recall what had happened to her.

Orm appeared in his Ocean Master costume in the next issue, which is set early in Orin's career as Aquaman and his rule of Atlantis. As in pre-Crisis continuity, Ocean Master desires the throne of Atlantis, having learnt his father was an Atlantean wizard. At this time neither he nor Aquaman knew of their relationship, although Aquaman would make the connection while recording the events.

During the Underworld Unleashed storyline, Ocean Master later started using mystical powers when sold his soul to Neron for a powerful trident which gave him great power, but caused agony if released. With this, he conquered the Dreaming City, a nation of Atlantean offshoots. He has been found by Aquaman, who was seeking to unite all the tribes of Atlantis. Aquaman convinced Ocean Master that they were half-brothers, however the pressure of this caused Orm's mind to snap.

Following this he briefly joined Lex Luthor's Injustice Gang, an "all archenemies" counterpart to the "Big Seven" Justice League. He also attempted to aggravate the tensions between Atlantis and the surface country of Cerdia.

Ocean Master clashed with the JLA again when he attempted to claim the remains of Atlantis following Aquaman's apparent death in Our Worlds At War.

Orm was last seen having used his mystical talents to alter reality so that he was Aquaman and Orin was Ocean Master. As Aquaman, Orm held Sub Diego under his evil rule. However the heroic Ocean Master was able to defeat him.

The Atlantis Chronicles suggests that brothers battling for rulership is a recurring theme in Atlantean history.

In Aquaman: Sword of Atlantis, Ocean Master has enslaved the Atlanteans who survived the Spectre's destruction of Atlantis, and is using them to mine industrial materials for the surface world.

In Infinite Crisis, Ocean Master became a member of the Secret Society of Super Villains.

In Final Crisis, Ocean Master is placed on the new Society's inner circle by Libra.


The New 52
In The New 52 (the 2011 relaunch and retcon of DC Comics' entire series), Ocean Master's origins are once again revised. According to the Atlantean advisor Vulko, the queen of Atlantis, Atlanna, left her first child, Arthur Curry, to live with his father on the surface world, thus protecting him from the effects of Atlantean tyranny. Atlanna is later forced to marry a member of the Atlantean Guard and gives birth to her second child, Orm. Twelve years later, Orm's father is killed and Atlanna dies under unknown circumstances, making Orm the new king. Vulko accuses Orm of killing Atlanna, but fails to produce evidence and flees. When Vulko is later 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.

Orm is eventually contacted by Aquaman, who suspected Orm to be the Atlantean hiring Black Manta to steal the relic scepter, an Atlantean object of power 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. It is also revealed that Aquaman allowed Orm to remain the king of Atlantis, on the condition that he would not invade the surface world.

During the Throne of Atlantis storyline, someone sabotages an aircraft carrier and provokes it into attacking Atlantis. Believing to be under attack from the surface, Orm leads Atlantean soldiers to invade the carrier and then wage war on the surface. Orm arrives in Boston, attacking seafarers and asking for his brother, Aquaman. Aquaman confronts Orm and attempts to talk sense to him, but they are interrupted by the Justice League without warning. Aquaman defends his brother, refusing to have him face extradition. Attacked on multiple fronts, Orm electrocutes then imprisons the Justice League within water cocoons. He sends the Justice League to the abyssal plain, while he attempts to sink the city of Boston.

While Orm and his Atlantean soldiers plant bombs in an attempt to sink the city and face off against the superheroes that Cyborg called in as reserves, they are attacked by a race of sea creatures known as the Trench. After the Justice League escape from the abyssal plain, Aquaman realizes Orm is not using the relic scepter to sink the city. Since the Trench can only be commanded with the relic scepter, someone else must be using it to manipulate the Atlantean war. The mastermind is revealed to be Vulko.

The Justice League arrive to battle both the Atlanteans and the Trench, while Aquaman attacks his brother and tries to convince him that Vulko is responsible for the Atlantean war. However, Orm refuses to listen, believing that Aquaman has been corrupted by the surface world. The Justice League manage to dispose of all the bomb detonators in Boston, but Orm tries to use his control helmet to summon a tidal wave. Mera's power turns the wave to hard water to stop it. Orm is defeated by Aquaman, who reclaims the throne and takes command of the deceived Atlantean soldiers. The Trench are returned home and Vulko is taken in for an Atlantean trial. However, Orm is remanded to Belle Reve for his crimes after abdicating the throne and losing political immunity in the process. As he is taken away, Aquaman apologizes to his brother.

Afterwards, the renegade Atlantean, Murk, makes plans to break Orm - now known by the media as the "Ocean Master," a name he despises - out of Belle Reve. While in prison, Orm is advised by his lawyer that he must plead guilty to the criminal charges against him. Murk and other Atlanteans arrive to free Orm, but return home when they receive a message that Atlantis is under attack.

During the Forever Evil storyline, Deathstorm and Power Ring invade Belle Reve, killing Orm's lawyer. During Belle Reve's prison break, Orm walks out to reclaim his Atlantean garb when a critically wounded prison officer begs for help; seeing that this officer was the only one who showed him any kindness, Orm kills him to end his suffering. He then runs into fellow escapees who are attacking a small-town diner, and whilst he is initially not bothered about confronting them, once they turn their attentions to him, he takes them out. A diner employee named Erin desperately pleads with Orm to save her young son Tommy, but he refuses, instead heading back to the ocean. However, he changes his mind, going back mid-way through his path to save him. In the aftermath of the attack, Orm now lives with Erin and Tommy, entertaining the latter with stories of Atlantis. Suddenly, Orm is confronted by the king of Xebel, Nereus, who offers him the opportunity to join him to allow the kings of the Seven Seas to rule Earth once more.
