Orm, also known as the Ocean Master, was the son of the King of Atlantis and Queen Atlanna and Aquaman's treacherous half-brother. After murdering Atlanna and usurping the throne, Orm was forced to fought against the Justice League, becoming one of their enemies.
Prince Orm was is part of Aquaman's loyal elite enforcers in the war against the Amazons. In the Flashpoint timeline, Ocean Master is part of Aquaman's loyal elite enforcers. When the Ravager got too close to the European coast, Atlanteans attacked the crew. Ocean Master used his trident to detonate Clayface. After mistakenly mentioning the late Queen Mera's name, Ocean Master was struck by his brother Emperor Orin who reminded him never to speak her name Orin then ordered Orm to prepare for the surface invasion of New Themyscira. Ocean Master monitored Hal Jordan's failed attempt to kamikaze into the doomsday weapon. During the invasion, after Black Manta was killed, Ocean Master opened fire on Batman but was nailed by the Flash. At some point, Ocean Master was killed by Amazonian archers during the battle.
He appears in a post-credits scene on an Atlantean ship, Ocean Master rose from the water holding the body of his king and vowing revenge on the surface world for the deaths of marine wildlife, which he mistakenly believes to have been an unprovoked attack — in reality, it was caused by Darkseid's invasion.
Throne of AtlantisEdit
Orm was Atlanna's second child, following her marriage to the previos King of Atlantis. At some point in his life, he somehow learnt of his half-brother from his mother's long-term love affair with a surface-dweller man. This was something he held Atlanna in contempt for, secretly accusing her of shameful adultery after learning of her machinations with that man.
His relationship with his mother had been strained following the death of his father, which he blamed the surface-dwellers for, even though repeatedly told him the truth that it was Darkseid responsible for this. Orm and his team of Atlanteans soldiers attacked and killed the crew of a submarine, Orm and Black Manta meet with Queen Atlanna (Orm's mother) to convince her to declare war on the surface world for the destruction caused by Darkseid's attack. After she rejects their proposition, Orm tells Black Manta to use missiles (that his men stole from a nuclear submarine earlier) loaded into his submarine to attack Atlantis, framing the surface world. Orm and Black Manta then demand that the Queen launch a war for the alleged act of terrorism from the surface. However, Queen Atlanta still refuses to strike and tells Manta to arrange a meeting with the Justice League to discuss a peace treaty.
After his men fail to kill his half brother, Aquaman, Orm kills Queen Atlanta and usurps the throne of Atlantis, once again framing the humans for killing his mother. As King, Orm dons his armor and becomes the supervillain "Ocean Master". When Aquaman and the Justice League arrive at Atlantis to stop him, Ocean Master defeats and captures them, offering them to the Trench. Ocean Master leads his Atlantean army to wage war with the surface, killing many humans in the process. The Justice League manage to free themselves and return to the surface to stop Ocean Master's army. Throughout the battle, Ocean Master easily defeated the entire Justice League until only his half brother remained. As Ocean Master was about to kill Aquaman, Cyborg broadcast a recording of Ocean Master confessing to murdering his own mother. After hearing the truth, the Atlanteans cease their attack. Ocean Master tries to explain his actions as Aquaman knocks Ocean Master out and becomes the new King of Atlantis. In the post-credits scene, Ocean Master is imprisoned in Belle Reve Prison. As Orm demands to speak to Aquaman, Lex Luthor appears and states that he has a proposition for him.
- Trident of Poseidon
- Orm wants Mera to be his wife, but she said she'd rather die, and Orm says it may come true. After taking the throne, he no longer has any interests in her when she sided with Arthur and the Justice League.
- Orm isn't a real villain in the original arc, being much closer to an Anti-Villain; he was simply manipulated by Vulko into attacking the surface in what he thought was fair retribution, and he also did not kill Atlanna; Vulko falsely suggests he did in order to motivate Aquaman to dethrone him. Besides that, he truly cares for Arthur as his brother and wishes him no harm. Vulko reveals himself the true Big Badof the original arc. This entire plot was dropped in the film, where Orm was made a straight-up villain, similar to his pre-New 52 incarnation.
