The people and creatures inhabiting the depths of the Seven Seas.
The old and highly advanced civilization inhabiting Atlantis, the legendary kingdom located deep underwater in the Atlantic Ocean. Inhabitants of the kingdom of Xebel, which is one of the Seven Kingdoms formed after the sinking of Atlantis, share the same biological features as those of Atlantis.
- All Myths Are True: The legendary kingdom of Atlantis does exist in the DCEU.
- Apparently Human Merfolk: Nothing can visually distinguish Atlanteans and Xebellians from humans except from their outfits and weapons. Required Secondary Powers aside, they kept the most human features in appearance from their ancestors compared to, in de-escalating order, the Fishermen, Brine and Trench.
- Fantastic Caste System: Only Highborn Atlanteans can breathe air, the rest need water-filled suits to survive out of the water.
- Hidden Elf Village: Much like the Amazons, they live isolated and hidden from other populations of Earth.
- Higher-Tech Species: They found a way to make plasma weapons and holograms powered by water and they have submarines coming in all shapes and forms that are way faster and more agile than anything humans can build.
- Horse of a Different Color: Atlanteans ride sharks, and Xebellians ride giant seahorses.
- Human Subspecies: They're basically humans who adapted to underwater life.
- Lost Colony: The Deserters and the Trench among the tribes that made up the original Atlantis. The Deserters became extinct when the Sahara turned into a desert and left no survivors, only structures buried deep beneath the sand. The Trench technically still exist, but they have mutated into savage beasts, and no one prior to Arthur wants to deal with them, for obvious reasons.
- More literally, Orm briefly mentions there was once a seventh kingdom that vanished, only known as The Lost Nation.
- Olympic Swimmer: Water is their natural element. They can swim way faster than humans (they can even propel themselves underwater like Superman does in the air) and effortlessly so.
- Precursor Heroes: The alliance of humans, Amazons, Atlanteans, Olympians and a Green Lantern that defeated Steppenwolf in the distant past are described by Diana as part of an "age of heroes". They also represented the Justice League's predecessors in more than one way.
- Required Secondary Powers: In order to resist the water pressure and swim as fast as they normally do, all the Atlanteans are much stronger and more resistant than a normal human. They're also immune to the cold of sea depths, and their eyes are adapted to see in the dark, a necessity when swimming at depths where there's no sunlight.
- Seahorse Steed: Xebellians ride giant seahorses.
- Secret Keepers: They were guarding a Mother Box since Steppenwolf's first invasion of Earth.
- Steampunk: The flashback to Atlantis's golden age shows bipedal vehicles that seem to be of this aesthetic, helped by the fact that they seem to be bellowing out steam.
- Super Not-Drowning Skills: They look like humans but, unlike humans, they can breathe normally underwater.
- Inverted as well with the "high-borns"; only they can breathe both water and air while normal Atlanteans would asphyxiate if they tried to breathe outside of water.
- Underwater City: The new Atlantis is one, of course, and Xebel is very likely one as well.
- Underwater Ruins: The Mother Box they possess is guarded in what has become such a setting.
- Vestigial Empire: When it was still a surface-based nation, it commanded a mighty, technologically advanced empire. Now, its a small collection of 4 opposing kingdoms that occasionally war against each other, with three other kingdoms having either become extinct, devolved into vicious beasts, or simply vanished. Orm seeks to unite the remaining 4 kingdoms... but in the end Aquaman ends up uniting all 5 instead, since he can control the Trench.
Atlantean Royal Family
- See his character page.
King Orm Marius / The Ocean Master
Affiliation(s): Atlantean Royal Family (under his reign)
Played by: Patrick Wilson
Dubbed by: Daniel del Roble (Latin American Spanish), Alexis Victor (European French), Frédéric Desager (Canadian French), Yuichi Nakamura (Japanese)
Film appearances: Aquaman
Other appearances: The Adventures of Aquaman & Mera
- "The war is coming to the surface, and I'm bringing the wrath of the Seven Seas with me!"
The king of Atlantis, Queen Atlanna's and King Orvax's son and Arthur/Aquaman's younger half-brother. He holds claim to the title of Ocean Master and, as such, wants to unite the surviving kingdoms that once composed the old Atlantis and turn them against the surface world in retaliation for the pollution and destruction of the seas by humanity.
- The Ace: Initially he's better than Aquaman at everything, which Vulko attributes to both his pure blood and perpetual underwater upbringing. This is subverted when Aquaman gains the trident of Atlan and lures him to fight on land.
- Actually Pretty Funny: When he reveals he's aware Vulko has been working against him, he orders him imprisoned but with the condition to "make sure he has a view" of Orm's victory. Following his surrender after being bested by Arthur, Vulko arrives to imprison him for his own crimes and repeats those same instructions to Orm in regards to witnessing Arthur's coronation as the new king. Orm actually smiles at Vulko's word choice, clearly not missing the irony of the reversal.
- A God Am I: He believes himself to be (metaphorically, at least) the Karathen incarnate only to meet the real one in the climax when Arthur uses it against him.
- Adaptational Villainy: In the New 52 comics which the film was based on, Orm did love his brother in spite of their opposition towards each other, and was generally a Noble Demon. Here, he Kicks The Dog several times, and is the one who performs the false-flag attack that leads to Atlantis declaring war on the surface. Though the pre-New 52 version was a straight-up villain.
- Adaptational Wimp: Though very competent and an excellent fighter, his power to control the oceans and the Trench through his crown are removed. Instead it's Arthur who commands the Trench in the Final Battle.
- Adaptation Dye-Job: Orm in the comics has black/dark brown hair, while here he is blond. The reverse is true for Aquaman. Incidentally, this makes Orm look more like the traditional comics Aquaman. According to Word of Saint Paul, they went for that look to make Orm more distinct from Arthur:
- Ambition Is Evil: His desire to be the Ocean Master leads him to commit several atrocities, including a fratricide attempt.
- Ancestral Weapon: His trident previously belonged to his father, King Orvax.
- Authority Equals Asskicking: As King, he's spent his entire life being trained for combat by the very best, and it shows. He's utterly formidable in battle underwater and dominates his first fight with Arthur.
- Badass Boast: Gives one before his first fight with Arthur.Orm: You have our mother's trident - powerful, but flawed, like her. I wield my father's, and it has never known defeat!
- Badass Cape: A Badass in Charge who wears a nice purple cape.
- Benevolent Boss: He's a pretty decent boss. He paid Black Manta a hefty amount of gold for a damaged submarine and even though Manta declined payment he still gave him the money. Later on he gave Manta next-generation Atlantean weaponry and armour, equipment that was even better than what Orm's own elites had and he just had Vulko imprisoned for treason instead of executing him outright.
- Big Bad: Of Aquaman, his plan is to force enough surviving colonies of Atlantis into a coalition so he can be crowned 'Ocean Master' and have an army large enough to declare war on the surface world.
- Bling of War: His battle gear is colorful and shiny, to say the least.
- Cain and Abel: Aquaman and Ocean Master are half brothers and they come to blows. Orm is the villain and Cain of the pair. He initially states that he would rather avoid the fight, but later both fights his brother and hires a mercenary to murder Arthur, something he can't do openly because of the promise he's made to an ally. Yet when he shoots the ship with Arthur down and believes his brother dead, he is not happy about it.
- Comic-Book Movies Don't Use Codenames:
- His full name from the comics, "Orm Marius", is not pronounced by anyone, but it does appear on a video game-like transparent display showing his pros and cons and those of Arthur right before their ritualistic duel starts.
- Downplayed, in the sense that "Ocean Master" is not a personal codename, but is an official ceremonial title for the supreme military leader of all of the underwater kingdoms, something similar to the title of dictator in Ancient Rome. Technically, Orm never even actually becomes the Ocean Master, as he never commands the majority of the military needed to claim it, but he does take possession of the name nonetheless and uses it when referring to himself.
- Composite Character: He seems to be one of both his pre-52 and New 52 comic characterizations. He has his pre-52's disdain towards his half-brother, and ambitions to take over the throne and go to war with the surface, however, he also does display his New 52's care for his half-brother (as seen when he offers to let him walk away and seems sorrowful when he believed he was dead), and his reasons towards war with the surface are semi-sympathetic, making him lean towards his more Anti-Villain characterization. He seems to develop more towards the latter characterization in the end when his mother returns, as he's filled with regret of his actions, joy of her survival, and does seem to appreciate the offer of talking his brother makes.
- Consummate Liar: He promises Mera's father not to harm her right before secretly hiring David Kane / Black Manta to kill both her and Arthur.
- Contrasting Sequel Antagonist: Like Ares from Wonder Woman (2017), Orm wants to wipe out humanity and is also the brother of the protagonist. However, Ares loathes humanity for its violent nature, relies on manipulating others and wears black armor. In contrast, Orm hates humans for polluting the seas, prefers to get his hands dirty, and wears shiny outfits. That said, Ares is still a formidable fighter in his own right and Orm is cunning enough to stage a False Flag Operation and deduced that Vulko is secretly aiding Arthur.
- Control Freak: He wants everyone, every living thing in the ocean to submit to him as his subjects.
- Darth Vader Clone: He is a villain who wears a cape and helmet while also happening to be related to the hero.
- Did Not Think This Through: Due to his plan being global in scale, if he did manage to beat Aquaman, it would only be a matter of time before his actions drew the attention of the Justice League. Superman alone would be more than enough to handle him even with Atlantis backing him up.
- Eco-Terrorist: He wants to start a war with the surface to stop the pollution of the oceans.
- Engineered Heroics: He almost single-handedly disposes of the submarine that attacks his forces and the Xebellians. Except he is the one behind the attack, as he paid Black Manta to get the submarine for him.
- Even Bad Men Love Their Mamas: As ruthless and bloodthirsty as he is, Orm dearly loves his mother. It's implied that her death is a serious motivator for his crusade against the surface, and when she returns, he surrenders peacefully and seems to acknowledge his own failures.
- Even Evil Can Be Loved: Both his mother and his half-brother care about him despite what he's done.
- Evil Overlord: He ascended to the throne of Atlantis and his plan to declare war on the surface world kickstarts the plot of Aquaman. Interestingly, he doesn't appear to be much of a tyrant to his own people. Atlantis appears to be thriving under his leadership and his people seem to adore him, if their reaction to his entrance during the Ring of Fire is any indication, although he does submit the other kingdoms by force.
- Evil Virtues: Courage, diligence, takes responsibility for his kingdom, is incredibly determined and capable of love. Before they duel in the area, Orm even offers Arthur one last chance to back down and live. As much as he hates Arthur for being a half-blood, they still share the same mother whom Orm loves dearly, and he outright stated that he doesn't want to kill him until he's left with no other choice.
- Expository Hairstyle Change: Whenever he is out of his depth (when Mera temporarily puts him out of action during his first duel with Arthur, or when he is defeated in the second duel), his orderly hair suddenly get very messy.
- Expressive Mask: The eyes of his Ocean Master helmet shows some amounts of expression in some frames.
- Face of an Angel, Mind of a Demon: His handsome clean-cut image is a very effective cover for his manipulative and violent tendencies.
- Fantastic Racism: He's not keen on surface-dwellers and wants them to suffer.
- Freudian Excuse: He hates Arthur because he holds him responsible for the execution of their mother Atlanna. Arthur being a son of Atlanna and a surface-dweller also makes Orm hate all surface-dwellers as well because of his pureblood upbringing. As his actor explains it:Patrick Wilson: Whats interesting is his personality. Sure, that's shaped by bad parenting by his father, a loveless marriage between his parents, and an older brother he never had but wished he did.
- Frontline General: When he leads his forces against the Brine, he does so from the front, tearing through soldiers left and right.
- Gold-Colored Superiority: When Arthur is brought before him in chains, Orm is the powerful ruling king who wears a golden costume. In the third act, it is Arthur who wears gold while Orm's armor has silvery elements, visually imparting that he is about to lose to Arthur before their second duel even starts.
- Good Hair, Evil Hair: He is the Big Bad with slicked-back hair.
- Horse of a Different Color: He rides a Tylosaurus in battle.
- I Shall Taunt You: Expertly provokes Arthur into their first duel on his turf, and later draws the Fishermen King into attacking him so he can kill him, all with words and facial expressions.
- Kick the Dog: Most of his villainous acts are still pretty reasonable given his upbringing and Freudian Excuse, but one evil act that stands out in particular is him killing the Fishermen King Ricou in cold blood, simply because he stands in the way of his plan, leaving the princess traumatized and a puppet queen under his rule without any choice in the matter.
- The Kingslayer: He kills the king of the Fishermen, Ricou, for refusing to join his campaign against the surface world.
- Knight Templar: Humans polluted and destroyed the oceans, and he wants to make them pay for this. More personally, he holds the surface responsible for tempting away and ultimately dooming his mother.
- Large Ham: Tends to yell his head off while extending his arms to get his audience to hype up or bolster his armies.Orm: RIIIIIIIIIISE!!! ATLANTIIIIIS!!
- Light Is Not Good: Has bright blonde hair and wears shining silvery armor into battle as well as a golden armor when he sits on his throne, but is an warmongering Evil Overlord.
- Manipulative Bastard: He orchestrates a fake submarine attack on King Nereus to convince the latter to side with him in a war against the land-dwellers. However, as he knows that the Fisherman King will still refuse to enter said war, he purposefully provokes him into attacking and then kills him in cold blood "in self-defense." That is enough to intimidate the King's daughter into submission.
- Moral Myopia: Hates surface-dwellers for damaging the ocean and endangering its inhabitants, yet he himself manipulates one kingdom to his side, strongarms another and goes to war with a third when they refuse to submit to his rule.
- Not-So-Well-Intentioned Extremist: Downplayed. Several characters think that he is motivated by power, since uniting the kingdoms to attack the surface world would make him the Ocean Master and the most powerful man on the planet; he is also clearly possessed of pure-blooded elitism as well as Fantastic Racism against the surface dwellers (though in this he seems like a typical Atlantean high born, rather than just a personality failing), not to mention a truckload of parental and sibling issues. However, that being said, his desire to destroy the surface world to stop them from ruining the oceans and to protect his people does seem genuine; it just isn't his only motivation as he so frequently claims.
- Perma-Shave: Unlike his half-brother, he is very clean shaven.
- Pet the Dog: Despite being an Evil Overlord through and thorough, he still has some moments of this:
- Even if he hates Arthur for being a half-blood and is the reason for their mother Atlanna being executed, he's still willing to give Arthur one last chance to walk away without harming him after Arthur tells him that he genuinely wants to connect with Orm as his half-brother.
- After discovering Vulko's treachery, Orm still respects the man enough not to kill him and instead just locks him up. Atlantean tradition treats treachery very seriously and would have dealt a death sentence to any traitor, with not even being members of the royal family being spared of this fate. The fact that Orm intends to kill Mera - the woman who was his betrothed - for betraying him, but lets Vulko live and not killing him on the spot after he did the same speaks volumes.
- Prongs of Poseidon: His Weapon of Choice is a trident he inherited from his father, King Orvax.
- Purple Is Powerful: He's determined to invade the surface, and he wears a bright purple and silver armor in the climax.
- Red Eyes, Take Warning: His mask has red lenses that coupled with the sculpted glaring eyebrows along the frames (that move with his real eyebrows) make him look like a demon.
- Royal Blood: He is the son of late king Orvax and queen Atlanna, and would protect his claim to the throne at all costs.
- Screaming Warrior: Especially in his duel with Arthur, he has a tendency to scream to rile up the crowd.
- Sibling Rivalry: Princeling Rivalry, to be more precise. He is Arthur's half-brother, and the two fight for the throne of Atlantis. Orm attempts to murder Arthur during both of their duels, when he shoots Mera's ship down as she and Arthur escape Atlantis, and by hiring Black Manta to do the killing for him. Yet he offers Arthur the chance to back down from the first duel and is visibly distressed when he thinks he has killed both his brother and Mera.
- Three-Point Landing: Foot, knee and trident upon the ship deck after surfacing in the climax.
- Tyrant Takes the Helm: Not so much a tyrant to Atlanteans themselves since they seem to appreciate him, but definitely one to the kingdoms he submits as the Ocean Master.
- The Unfavorite: Deconstructed. Besides his deceased father, everyone in his inner circle likes or winds up liking Arthur more than him from Vulko to Mera to (as he rightfully suspects) his own mother. But as the ending of the film proves, that doesn't necessarily mean that his mother doesn't love him.
- Villainous Cheekbones: He has a narrow face and high cheekbones, which is fitting for a Big Bad.
- Villainous Valor: Despite the inevitably of him losing to his brother due to his inferior trident and fighting in an unfamiliar environment, he still puts up a hell of a fight against him, to the point where Arthur has to destroy his trident to finally put him down.
- Villain Has a Point: Part of his motive is that he holds the surface world responsible for polluting the oceans and infringing on the Atlantean way of life. Not a single character disagrees with him on this, they just think that trying to wipe out all of humanity for it is a step too far.
- White Hair, Black Heart: His silvery white hair indicates that he is the villain in the film.
Affiliation(s): Atlantean Royal Family (loyalist of Arthur/Aquaman)
Played by: Nicole Kidman
Dubbed by: Dulce Guerrero (Latin American Spanish), Danièle Douet (European French), Anne Bédard (Canadian French), Miyuki Sawashiro (Japanese)
The former queen of Atlantis. A human lighthouse operator, Thomas Curry, found her washed up on his island after she fled an arranged marriage with King Orvax. The two of them fell in love and Arthur/Aquaman was born of it.
- Action Mom: She can hold her own very well with her quindent. She also rescues Mera from a tylosaur and is one of the few people to encounter the Karathen and survive.
- Adaptational Nice Guy: In the comics she refused to believe Arthur was her son at first, and nearly had him killed. Here she is a loving mother from the get-go.
- Ancestral Weapon: The quindent Arthur uses in Batman v Superman and Justice League was hers.
- Daddy Had a Good Reason for Abandoning You: Gender flipped. Atlanna did not want to leave Thomas and their son, but she had to in order to save their lives.
- Huge Girl, Tiny Guy: Downplayed. She's 5'11 compared to Thomas Curry's 5'8.
- Interspecies Romance: She had a relationship with Thomas Curry, a human lighthouse keeper. Arthur was born of it.
- Mama Bear: Three Atlantean soldiers find out very quickly that getting between her and her son is not a very good idea as she quickly kills each and every one of them. In a movie where people are as diplomatic as possible, she didn't try to talk them out of taking her back, she just outright killed them.
- Missing Mom: To Arthur. At first he thinks she has simply abandoned him, but as a teenager Vulko reveals to him that she was executed. It's later revealed that she was trapped in the Hidden Sea.
- Mystical White Hair: She has platinum blonde hair and is the queen of Atlantis.
- Morality Pet: Is ultimately this for Orm as he immediately stands down upon seeing her alive.
- Nemean Skinning: Officially, she was "sacrificed" to the Kingdom of the Trench. For most Atlanteans, exposure to the rabid (and positively cannibalistic) Trench is a one-way trip. Testament to her badass credentials, she managed to survive fighting the Trench and reach the Hidden Seas—even managing to fashion camouflage from her tattered attire and what seems to be Trench fins/body parts, the better so she blends among them. She even manages to track/rescue both Arthur and Mera when they in turn get overwhelmed by the Trench.
- Nice Girl: Only wants peace between the oceans and the surface and loves both her sons dearly.
- The One That Got Away: She abandoned both her human lover and their son to keep them safe. Almost 30 years later, she reunites with Tom.
- Parental Abandonment: She abandoned Arthur when he was very young, and he grew up resenting her as explained in Justice League. Mera states that Atlanna did so "to save his life". The Aquaman film clarifies that she left to protect Arthur and his dad from the wrath of King Orvax, as Atlantean soldiers were never going to stop coming for her.
- Parental Favoritism: She abandoned the son she had with her human lover, but raised Mera like a daughter. It is not entirely clear how positive her relationship with her otherwise son, Orm, is (especially considering her own "execution" warped his memory of her). Contextual dialogue between Mera and Orm, however, suggest that is likely both were raised under her supervision and tutelage. However, the moment Orvax ordered her "sacrifice", Orm was forced by circumstance to reject everything she stood for, while Mera, independent as she is, continued to take her direction and influence in life.
- Parental Substitute: She took Mera in and raised her when her parents were fighting in wars.
- Rescue Romance: Thomas Curry first met her when he found her unconscious in a shore.
- Silk Hiding Steel: She looks regal and delicate, but can match even trained soldiers in close-quarter combat and survived twenty years in exile.
- Spared by the Adaptation: She doesn't last as long in the comics as she does in this movie.
- Statuesque Stunner: She stands 5'11 (the tallest woman in the DCEU to date) and is strikingly beautiful. When she reunites with her son, he isn't that much taller than her (Momoa is 6'4).
- Woman in White: She's mostly wearing a splashed white outfit, which seems to be a royal garb of sorts. When Arthur and Mera meet her in the Hidden Sea at Earth's core, she still is rocking the same outfit, albeit with some armor she salvaged over the years.
Affiliation(s): Atlantean Royal Family
Appearances: Aquaman (mentioned)
The father of Orm and king of Atlantis before him. Atlanna was his unwilling betrothed.
- Abusive Parents: He raised Orm to hate humans and shaped him to be a ruthless fanatic.
- Ancestral Weapon: His trident, which Orm inherited.
- Arranged Marriage: Atlanna was forced to marry him, and chose to flee. She returned to marry him after he sent soldiers to her family's home.
- Crazy Jealous Guy: After Atlanna fled to the surface rather than marry him, he tracked her down and sent a war party after her; she fought them off but ended up returning to Atlantis anyway, believing he would send an army after her if she didn't. And it only got worse after she did go back to Atlantis to marry him; once he learned she'd had a son by Thomas Curry, he had her sacrificed to the Trench.
- Evil Counterpart: To Thomas Curry. Both had relations with Atlanna and bore heirs to the throne. The difference was that Thomas and Atlanna genuinely loved each other while Orvax only married Atlanna for political reasons and was willing to kill her for going against his will. Additionally, Atlanna only returned to Orvax because his will threatened her family and she believed he'd never stop hunting her. Whilst with Thomas, she gladly returns home to him as soon as she is able to and Thomas never stopped waiting for her to return even when she was believed dead.
- Fantastic Racism: He hated surface dwellers.
- Greater-Scope Villain: He was responsible for separating Atlanna from Thomas and Arthur and giving her the death sentence. He also shaped Orm into the man he is now. Despite being dead and unseen (without even a flashback), the consequences of his actions still resonate within Atlantis and Earth.
- Hate Sink: Orvax manages to be one despite not appearing in-person and supposedly being long-dead. Everything that happens regarding Orm, Atlanna, Arthur's childhood and his kingdom is a result of his own arrogance, prejudice and entitlement. It really says something that Atlanna's reaction to being in an Arranged Marriage with him was to flee her home, and that she only returned to him because he sent soldiers to the home of her new family. And then he had her executed after she gave him an heir. The instant Orm sees that his mother is alive and she tells him the beliefs his father instilled in him were wrong, he peacefully surrenders.
- Posthumous Character: He is dead for an unspecified amount of time in present day.
- Predecessor Villain: His beliefs were the catalyst for everything bad that happens throughout Aquaman. He passed his prejudiced views onto his son, who manipulated the Atlantean kingdoms into war and upgraded Black Manta into a formidable foe for Aquaman. He also forced Atlanna to leave Arthur when he was very young, giving him issues well into his adult years.

Played by: Graham McTavish
Dubbed by: Santos Alberto (Latin American Spanish), Keisuke Ishida (Japanese)
An ancient king of Atlantis who forged a trident that grants power over the oceans. He ordered experiments on the trident's powers and these destroyed and sank Atlantis. He ended up exiling himself in an unknown location beyond the Hidden Sea and took the trident with him.
- Excalibur in the Rust: Averted. His remains still wear his suit and is still in great condition millennias after Atlan passed away, thus becoming Aquaman's suit. As for the Trident, not only is it not covered in anything as one would expect (such as barnacles), it also still radiates.
- Hologram: He appears to Aquaman and Mera in the form of a pre-recorded hologram that activates using the key Vulko handed to them.
- Long Dead Badass: He died in ancient times, and was the owner of a tremendously powerful weapon.
- My God, What Have I Done?: His attempts to weaponize the trident resulted in Atlantis sinking into the ocean. He disappeared in self-imposed exile, to ensure that the trident's power would not fall into the wrong hands and to atone for his actions.
- Prongs of Poseidon: The trident he forged, which grants control over the sea itself.
- Speaks Fluent Animal: According to Karathen, he had the ability to communicate with sea life, just like Arthur/Aquaman.
- Ultimate Blacksmith: His trident was forged under his guidance with steel brought to him by Poseidon himself.
Ancient Atlantean King
Affiliation(s): Atlantean Royal Family, First alliance against Apokolips
Played by: Julian Lewis Jones

An unnamed ancient king of Atlantis who took part to the battle against the first invasion of Earth by Apokoliptians with his people.
- Badass Beard: Led the Atlantean charge to help repel an Apokoliptian invasion, and sported a beard.
- Cool Crown: His crown, which was akin to a helmet.
- Dismantled MacGuffin: He came to be in charge of one of the three Mother Boxes following Steppenwolf's first defeat on Earth.
- Frontline General: He led his troops in battle against Steppenwolf.
- Long Dead Badass: He fought alongside the Amazons, Olympians, Humans and a Green Lantern against the forces of Apokolips during his first invasion of Earth and put the Mother Box that was given to Atlanteans inside an underwater stronghold.
- No Name Given: His name is not mentioned at any point.
- Prongs of Poseidon: He fought with a trident during the battle against Apokoliptians.
Affiliation(s): Atlantean Royal Family (in service or Orm, but actually a loyalist of Arthur/Aquaman)
Played by: Willem Dafoe
Dubbed by: Jesse Conde (Latin American Spanish), Éric Herson-Macarel (European French), Sylvain Hétu (Canadian French), Yōhei Tadano (Japanese)
Appearances: Justice League (Deleted Role) | Aquaman
The Vizier of the king of Atlantis and Arthur/Aquaman's secret mentor.
- Adaptational Attractiveness: The comics version of Vulko is overweight, while Willem Dafoe is very lean and gaunt.
- Adaptational Heroism: In the comic, it was Vulko who orchestrated the "surface" attack as part of a Batman Gambit to force Arthur to defeat Orm and become king. Here, Orm is responsible, and Vulko is entirely blameless. Though the pre-New 52 version was benevolent.
- Call to Adventure: In a deleted scene that was originally planned at the end of Justice League, he came at Arthur with Mera to convince him to return to Atlantis. Arthur refused and went back to his father instead.
- Dark Is Not Evil: Vulko wears black clothes and has dark hair, but he is one of Arthur's closest allies.
- The Good Chancellor: As Vizier of Atlantis, he is the voice of reason in Orm's court, and works behind his back to stop a genocidal war. Though Orm eventually deduces his hidden agenda and has him imprisoned.
- Horse of a Different Color: He rides a hammerhead shark during the meeting between Orm and King Nereus.
- Javelin Thrower: As part of Arthur's training, he throws Atlanna's quindent at him to have him catch it with his hands.
- Loyal to the Position: Vulko's loyalty is to the throne of Atlantis, and as far as he is concerned that means making damn sure the best possible candidate occupies it.
- Mentor Archetype: He tought a young Arthur Curry about his Atlantean heritage and trained him in secret in preparation for his return to Atlantis.
- Old Retainer: He's been serving the Atlantean royal family since at least the time of King Orvax.
- Sheep in Sheep's Clothing: Despite being played by well-known villain actor Willem Dafoe, and his role in the comics as the true villain of Throne of Atlantis, from which the movie takes much of its plot, he is entirely heroic.
Affiliation(s): Atlantis (in service of Orm)
Played by: Ludi Lin
Dubbed by: José Ángel Torres (Latin American Spanish), Martin Faliu (European French), Takayuki Nakatsukasa (Japanese)
Orm's enforcer in chief.
- Adaptational Attractiveness: His scars are much less disfiguring than in the comics, and his actor is much more of a Pretty Boy compared to his comic self's more brutish appearance.
- Adaptational Villainy: While his comics self is a Noble Top Enforcer with a strong moral code, this version is entirely willing to attempt to kill Mera on Orm's behest behind Nereus's back.
- Charged Attack: His armor's arms are equipped with a chargeable Megaton Punch system.
- Flat Character: We're not given any insight as to his thoughts on Arthur or Mera's actions. He just does what Orm tells him to do.
- Hyper-Competent Sidekick: Manages to beat Arthur in a dry environment, something even Orm couldn't accomplish. Although he did so thanks to his armor's Megaton Punch ability.
- Literal Disarming: Mera cuts off his hand, though in a bit of a subversion, he's able to keep on fighting until she breaks his helmet, due to his Powered Armor automatically sealing the wound.
- Meaningful Name: 'Murk' is anything that makes it difficult to see through something this is otherwise completely transparent, ususally darkness or some obscuring mist. Often used to describe 'murky water'.
- Megaton Punch: His armor is equipped with a charge system on his arms to deliver punches powerful enough to send Arthur flying and knock him out.
- Mobile Fishbowl: As a non-high born, he needs a watery environment to survive in the surface world, and his Powered Armor is equipped with this. It gets wrecked when he fights Mera, and he promptly rushes to a toilet bowl and puts his head in it to stop his suffocation.
- Mook Lieutenant: During the hunt for Arthur and Mera, he commands a squad of elite Atlantean soldiers who are equipped with advanced armors, alongside Black Manta.
- Powered Armor: The advanced armor he dons serves both for combat and as Mobile Fishbowl for his own survival.
- What Happened to the Mouse?: The last we see of him, he's desperately sticking his head into a toilet just to continue breathing after his helmet is broken.
- White Hair, Black Heart: Like his boss, Murk has white-blond hair and is an antagonist.
Affiliation(s): Atlantis (in service of Orm)
The soldiers of Atlantis.
- Elite Mooks: The red armor soldiers are the most dangerous and they are led by Murk.
- Expy: Of the Imperial Stormtroopers from Star Wars. Some of them wear white armour, others work as blaster weapons-equipped enforcers to a warmongering ruler who submits other races by force and at one point are seen working alongside a figure who's clad in black armor and has a red energy beam weapon.
- Faceless Goons: Their helmets are filled with water and their blue color makes it difficult to see their faces.
- Hologram: They are equipped with water-based holographic technology to transmit messages from Orm.
- Horse of a Different Color: They ride sharks in battle.
- Jet Pack: The red armored ones are equipped with jet packs.
- Logical Weakness: Shatter their helmets and they suffocate from a lack of water to breathe.
- Mobile Fishbowl: They need a Powered Armor to survive in the surface world as they're not high born.
- Mooks: Orm's expendable soldiers lacking in personality who get mowed down by Atlanna, Arthur/Aquaman and Mera in various ways.
- Plasma Cannon: They are equipped with water-powered weapons that turn water into plasma. Orm gives some of that technology to David Kane, who adapts it to his helmet and styles himself as Black Manta.
- Powered Armor: They wear armors that look like they come straight out of a Space Opera. The red armors are reinforced compared to the white ones.
- Praetorian Guard: The highest-ranking members wear red armour.
Kingdom of Xebel
Affiliation(s): Xebellian Royal Family, Atlantis (loyalist of Arthur/Aquaman)
Played by: Amber Heard
Dubbed by: Marisol Romero (Latin-American Spanish), Chloé Berthier (European French), Nadia Paradis [Justice League], Camille Cyr-Desmarais [Aquaman] (Canadian French), Rie Tanaka (Japanese)
Film appearances: Justice League | Aquaman
Other appearances: The Adventures of Aquaman & Mera
The daughter of King Nereus, Mera was raised by Queen Atlanna betrothed to Orm. She convinces Arthur Curry/Aquaman to go against Steppenwolf and he ends up joining the Justice League as a result. Later, she convinces Arthur to claim his heritage as king against Orm to protect both the remaining kingdoms of the Seven Seas and the surface world from the latter's wrath.
- Action Girl: When she is capable of holding her ground against a Physical God like Steppenwolf with her powers and survive, it's hard to argue that she isn't one.
- Ace Pilot: She demonstrates amazing piloting skills in an underwater setting as she and Arthur escape inside her ship while being chased by Atlanteans. In the end, she successfully goes above the wall encircling Atlantis, something that she herself said should never be attempted because of the multitude of guns stationed atop said wall. If not for Orm's shot, they would have gotten away unscathed.
- Adaptational Heroism: Downplayed but in the comics, she and Arthur first met when Mera tried to kill him. Here she is his ally from the beginning.
- Adaptation Name Change: Unlike her comics counterpart who has Only One Name, this version's full name is Princess Y'Mera Xebella Challa.
- Adaptation Origin Connection: Both her and Nereus are two separate characters in comic lore, with Mera was supposed to be Nereus' betrothed and was suppose to become his Queen. In the film, she is his daughter and Nereus is married someone else.
- Adaptation Personality Change: One consistent trait of Mera in the comics would be her Fiery Redhead tendencies, and indeed is usually the more head-on confrontational between her and Arthur. In the film series, while she definitely is the more proactive one when it comes to the plot, she is also way more circumspect in doing things—never initiating anything unless she knows what she is doing.
- Adorkable : Its not to a significant extent, but she does show a quirky, child like wonderment when she and Arthur are in Italy and taking in the sights. She's just adorable here.
- Arranged Marriage: As a Xebellian princess, she is forced to marry Alantean king Orm. Subverted when she runs away and eventually becomes a girlfriend of Aquaman who duly replaces Orm as the king.
- Beauty Is Never Tarnished:
- Downplayed in Justice League. Her forehead is slightly bruised after her brief brawl with Steppenwolf.
- Downplayed again in Aquaman, where she takes several noticeable wounds during the battle in Sicily, but still fares better than Arthur since she was not the main target of Black Manta's ire.
- Before that, she trekked through the Sahara and later to Sicily and looks no worse for wear.
- Boke and Tsukkomi Routine: During a trek through the Sahara Desert to find an Atlantean outpost, Arthur acts like a mouthy goofball over every little thing while Mera can only roll her eyes at his childish nature.
- Boobs of Steel: Downplayed. She's not as heavily stacked as the most common examples of this trope, but well-endowed nonetheless (as demonstrated by the constant cleavage).
- Civvie Spandex: Wears an emerald green skin-tight suit with hexagon pattern detailing underneath her battle armor.
- Cool Crown: The headdress◊ she wears in Justice League is both regal and plenty sharp-looking.
- Deadpan Snarker: She's constantly making snarky remarks towards Arthur in Aquaman.
- Deuteragonist: In Aquaman. She has the second-highest screentime of the film after the titular character, and they spend much of the film working together in their mutual goal to stop the war between Atlantis and the surface.
- Distracted by the Sexy: When she first meets Arthur/Orin, she's a little bit flustered by his shirtlessness.
- Drives Like Crazy: While escaping the Atlantean capital, she does some "creative" driving on her ship, to Arthur's utter terror and to such a degree of lunacy that even the hydrocannons on the walls can't score a direct hit.
- Early Installment Character-Design Difference: As you can see in her photos here, her hair clearly changed in tone between her debut in Justice League and her main outing in Aquaman, becoming a brighter shade of red from the relatively-realistic ginger. Comparisons to Ariel from The Little Mermaid are not entirely inaccurate. Maybe dyeing is a thing in Atlantis too.
- Fish out of Water: Once she's on the run with Arthur, Mera is clearly puzzled (but also amazed) by the surface world. In a Sicilian town, she even eats a rose out of a gifted bouquet!
- Happily Adopted: Queen Atlanna raised her, because her parents were too busy fighting wars.
- Hyper-Competent Sidekick: She realizes the danger Orm poses and enlists Arthur to stop him, saves Arthur's father from drowning, smuggles Arthur into Atlantis, saves him when he loses the first duel with Orm and is about to be killed by his younger half-brother, leads him to the exact place in the sands of Sahara where he can decipher the secret message, steals (ahem, "borrows") a boat to get to the Trench and takes care of wounded Arthur, fights with him in the Final Battle, sways her father and her people to his side to avoid further bloodshed and advises him to duel Orm again out of water where he'll be weaker. With her heightened sense of responsibility to both her people and the world at large, she would make a fine Ocean Master herself if she were only eligible for the title.
- Heroes Want Redheads: She's a redhead, and bound to become the Love Interest of one of Earth's greatest heroes.Arthur: Redheads. You gotta love 'em!
- Kung-Fu Wizard: Even without her powers, she's still a capable martial artist with the Super Strength common to all Atlanteans, as Murk and his commandos find out the hard way.
- Lady of Black Magic: A Xebellian princess who conducts herself with femininity and composure; she has great hydrokinetic powers, her eyes and hands glowing bright blue as she creates powerful hard water rays and projectiles.
- Leitmotif: Orchestral versions of "Everything I Need" plays during scenes related to her and Arthur's romance.
- Making a Splash: She has hydrokinetic powers. She can summon underwater whirlpools and air domes, for instance. In the surface, she manages to create water spikes with the contents of a winery.
- Ms. Exposition: She spends a huge chunk of Aquaman explaining Atlantean customs to the titular character.
- Ms. Fanservice: She is a redhead in a green form-fitting outfit with an open cleavage. Need we say more?
- Occult Blue Eyes: When she casts her water magic, her eyes turn unnaturally bright blue.
- "The Reason You Suck" Speech: Gives a much-needed one to Aquaman in Justice League, telling him to get over his self-pity over his abandonment issues and do his duty by following Steppenwolf to the surface.
- Power Glow: When using her hydrokinesis, there is a visible blue glow in her eyes and around the water she manipulates.
- Pretend Prejudice: She dismisses Arthur as half-breed in front of Orm, while secretly rooting for him.
- Redhead in Green: She's a redhead, and her most common outfits are green.
- Replacement Goldfish: Atlanna took her in and raised her as her own after she was forced to abandon her son, although she abandoned Arthur for a good reason: Mera is not her potential heir subjected to Fantastic Racism, but Arthur is.
- Royal Blood: She's the daughter of King Nereus of Xebel, and as such is forced into an Arranged Marriage with the king of Atlantis, Orm. She escapes this fate.
- Royals Who Actually Do Something: She is a Xebellian princess who does everything in her power to stop Orm.
- The Swarm: She telepathically sends a torrent of fish to attack Steppenwolf.
- Warrior Princess: Xebel has a warrior culture, she's the daughter of their sovereign, and is no exception to their warrior spirit.
- What the Hell, Hero?: Mera chews out Aquaman for disrespecting his mother's memory and criticizes him for being a Prodigal Hero in Justice League. Thanks to this, she is able to convince him to go after Steppenwolf, and he joins the League as a result.
- Woman in White: Her formal dress to watch the duel between Orm and Arthur is white and silver, which strikes a contrast with her green bodysuit. She ditches it as soon as it's clear that Arthur will need to be rescued, which is symbolic of her casting aside her title and role etc. because she can't go back to Atlantis after betraying it.
- Women Are Wiser: Was smart enough to memorise and destroy an encoded message so that it couldn't fall into the wrong hands. Arthur didn't think that far ahead.
Affiliation(s): Xebellian Royal Family, Orm's Alliance
Played by: Dolph Lundgren
Dubbed by: Gerardo Vásquez (Latin American Spanish), Luc Bernard (European French), Marc-André Bélanger (Canadian French), Akio Hirose (Japanese)
The king of the Atlantean colony of Xebel, in the Bermuda Triangle, and Mera's father.
- Action Dad: He is Mera's father and is said to be a formidable fighter.
- Adaptational Heroism: His comic book incarnation was a warlord who intended to marry Mera against her will. Here he is at worst a Noble Demon who insists his daughter not be harmed despite her betraying King Orm. Also during the climactic final battle he immediately turns on Orm when he discovers Arthur wields Atlan's trident, showing he is loyal to Atlantis' sacred traditions..
- Adaptation Origin Connection: Both him and Mera are two separate characters in comic lore, with Mera was supposed to be Nereus' betrothed and was suppose to become his Queen. In the film, Mera is his daughter and Nereus is married to someone else.
- Age Lift: As a result of being Related in the Adaptation by being Mera's father, Nereus is a few decades older than his comic counterpart.
- Badass Beard: He's a Badass in Charge with a short beard streaked with red and silver.
- Battle Couple: He and his wife are frequently fighting wars, hence why Mera is basically raised by Atlanna.
- Dragon-in-Chief: A downplayed example, but Orm needs the great military of Xebel to force the other colonies into going along with his coalition and have himself crowned 'Ocean Master'.
- Even Evil Has Standards: He was appalled when Orm killed King Ricou for refusing to join their alliance. Also, despite everything Mera does to defy him he still loves her, and warns Orm that if he tries to kill her their alliance will be over.
- Horse of a Different Color: Like all Xebellians, he rides a giant seahorse.
- I Have No Daughter!: Mera assumed that her father will disown her for betraying him, but this turns out to be an aversion; Nereus demands that Orm ensure Mera returns unharmed.
- Karma Houdini: Faces no consequences after Orm is defeated and imprisoned, even though he willingly supported his plans for war. One can assume this is because he immediately defects when his daughter told him Arthur had the special trident and was thus the true king. He was also likely harboring reservations on following Orm after the latter brazenly murdered King Ricou.
- Large and in Charge: Stands 6'5 and is the king of the Xebel colony.
- Obfuscating Stupidity: He is a lot smarter than Orm gives him credit for, as he sees right through Orm's transparent False Flag Operation. But because the end result aligns with what he wants, he pretends not to notice the absurd Contrived Coincidence.
- Papa Wolf: After Mera helps Arthur escape from the Ring of Fire, she thinks that her father has given up on her and will never forgive her. She is dead wrong. Nereus makes it clear to Orm that he wants Mera back without a scratch on her, or their alliance is dead.
- Punch-Clock Villain: Despite his allegiance to Orm, he's far from a bad person. Fighting against the surface just seems like the practical choice for him. Anyone in his shoes would most likely make a similar decision.
- Related in the Adaptation: Nereus was unrelated to Mera in the comics, being intended to be her betrothed before she met Arthur. Here, he's her father.
Kingdom of the Fishermen
A race and kingdom that emerged after the sinking of the original Atlantis. Its inhabitants evolved from humans into fish-like humanoids.
- Adaptation Name Change: They are called "Tritonians" in the comics originally. Oddly enough, "Fisherman" is a moniker originally used by several enemies of Aquaman in the comics.
- Fish People: They're a humanoid species that has evolved from human Atlanteans due to living deeper, gaining fish tails, scales and gills.
- Human Subspecies: They're a human branch that evolved from ancient Atlanteans into fish-like humanoids in order to adapt to greater depths. Theyre referred to, and seem to be, the most elegant and "advanced" mutation, in contrast to the more primitive and crustacean Brine and the outright animalistic and monstrous Trench.
- Our Mermaids Are Different: They lean much more on the 'fish' side of merfolk than Atlanteans and Xebellians.
- Proud Scholar Race: They're philosophers and scholars, and wish to educate the surface dwellers rather than wage war on them.
- Rousseau Was Right: According to King Ricou, they have long wished to make contact with the surface so they can teach them how to take better care of the oceans rather than forcing them to Kneel Before Zod like Orm wants to do.
- Warrior Poets: They have war technology, but also favored developing their own refined culture, almost to the point of being Martial Pacifists, which doesn't suit Orm's plans to wage war against the surface world and prompts him to threaten their rulers with Join or Die.
- They seem to be the most inclined towards culture, and even have some minor Bling Bling BANG aspect to their weaponry.
Citizenship: Kingdom of the Fishermen
Affiliation(s): Royal Family of the Fishermen
Played by: Djimon Hounsou
Dubbed by: Daniel Abundis (Latin American Spanish), Frantz Confiac (European French), François L'Écuyer (Canadian French), Takashi Matsuyama (Japanese)
The king of the Fishermen.
- Adaptational Heroism: In the comics he was a member of Aquaman's Rogues Gallery. Here he is an ally of Atlantis.
- Adaptation Species Change: He's a fish-like aquatic humanoid who lives under the sea, in contrast to the comic book version of the Fisherman, who was a human criminal with a high-tech diving suit.
- Bling of War: He wears a gilded armor.
- Casting Gag: Mild example. Djimon Hounsou had previously played a human fisherman who was heroic and noble against ugly circumstances.
- Impaled with Extreme Prejudice: Orm stabs and kills him, after the Fisherman King refuses to join his alliance.
- Prongs of Poseidon: He has an elaborate trident.
- Reasonable Authority Figure: Is against a war with the surface world because he understands how terrible it would be for both sides. Orm is not happy with this, so he stabs him.
- Shout-Out: He is named in tribute to actor, stuntman and underwater cinematographer Ricou Browning, who played the Gill-man in Creature from the Black Lagoon.
- We Hardly Knew Ye: He has less than one minute of screentime. His immediate death proves that Orm really means business with his plans.
The Fisherman Princess/Queen
Citizenship: Kingdom of the Fishermen
Affiliation(s): Royal Family of the Fishermen, Orm's Alliance
Played by: Sophia Forrest
Dubbed by: Fernanda Robles (Latin American Spanish)
The young heir to the Fisherman king Ricou.
- Bling of War: She wears a gilded armor just like her father.
- No Name Given: Her name is not specified, unlike her mother's and father's.
- Oh, Crap!:
- Her face expression upon seeing Karathen emerging from the bottom of the ocean says it all.
- She's the first to vocally point out that Arthur/Aquaman found a way to control the Trench (with Atlan's trident), as he's using them to swarm her forces as well as the Atlantean and Xebellian armies.
- Puppet Queen: She becomes queen after her father's death by the hand of Orm, and she's forced to side with Orm and lead her troops against the Brine armies alongside Atlanteans and Xebellians lest she wants to get killed as well.
- You Are in Command Now: She becomes de facto queen of the Fishermen when Orm kills her father, and she is seen leading her troops in the Final Battle.
Kingdom of the Brine
A race and kingdom that emerged after the sinking of the original Atlantis. Its inhabitants evolved from humans into crustacean creatures.
- Badass Army: What little is shown of that race consists of one enormous army, as seen in the climactic battle. Though clearly outmatched by Orm's coalition, they still manage to inflict significant damage to his forces before Arthur and friends arrive to turn the tide.
- Beast of Battle: The Brine army is backed by absolutely massive crabs that serve as their equivalent of Walking Tanks.
- Fish People: The "Crab People" variant. They are descended from Atlanteans who evolved into humanoid crustaceans, likely to adapt to the magmatic seafloor they ended up using as habitat.
- Giant Enemy Crab: To Orm, the Brine are enemies for refusing to join his side, and not only are the regular members of the Brine human-sized crustaceans, but they have truly massive crabs as beasts of battle.
- Human Subspecies: They're a human branch that evolved from ancient Atlanteans into crustacean-like creatures in order to adapt to deep seafloors.
- Mutants: That species has evolved (or de-evolved) from humans who once populated Atlantis.
- Power Pincers: They gained crustacean pincers when evolving.
- Rock Beats Laser: They fight with things as crude and simple as lava-throwing catapults against advanced Atlantean and Fishermen submarines, and it's enough to destroy them.
- Scorpion People: Some of the Brine have grown multiple arthropod legs and kept a humanoid torso when evolving, while others such as the king kept walking on two legs and grew armor on their back.
- Violence Is the Only Option: They don't bow down to any other power, so subjugating them by force is the way to go for any would-be Ocean Master. Orm doesn't even bother to diplomatically try gaining them as allies and attacks them after rallying Xebellians to his cause and press-ganging the Fishermen into his ranks.
The Brine King
Citizenship: Kingdom of the Brine
Played by: John Rhys-Davies (voice), Andrew Crawford (motion capture)
Dubbed by: César Soto (Latin American Spanish), Denis Roy (Canadian French), Shirō Saitō (Japanese)
The King of the Brine.
- Badass Baritone: Provided by John Rhys-Davies, and he puts up a fierce fight against Orm.
- Badass Boast: He has these words as he rallies his troops before leading them into battle:Brine King: We will not bow to Atlantis! We're gonna give them a fight that they'll never forget!
- Defiant to the End: Even knowing his kingdom will fall to Orm upon being defeated, he refuses to submit and prefers dying in battle. When Orm disarms him, has him at the end of his trident and demands that he submit or be killed the Brine King simply responds:Brine King: You can take my army, you soft bellied slug! But YOU WILL NEVER HAVE MY ALLEGIANCE!!!
- Frontline General: He bravely leads his troops in battle.
- Large Ham: Despite only having a few seconds of screen time, all of his quotes were done in a defiant and yelling manner.
- Literal Disarming: Orm cuts off his right pincers-arm (which was holding his trident) during the Final Battle.
- No Name Given: He is only known as the Brine King.
- Prongs of Poseidon: Fights with a trident, albeit a more crudely crafted one than those made by either Atlanteans or Fishermen.
- Uncertain Doom: After Arthur interrupts the battle, he is not shown again and his final fate remains ambiguous.
A savage race of underwater dwelling creatures. They are the most extreme case of evolution (or de-evolution) of ancient human Atlanteans and, unlike the Fishermen and the Brine, have practically become beasts with nothing left of a civilized behaviour.
- Always Chaotic Evil: They're seemingly motivated purely by their hunger for meat.
- Animalistic Abomination: They are actually a branch of the original Atlanteans, but evolved in the deep seas to become what they are now. They somewhat resemble anthropomorphic angler fish and they're animalistic enough that Arthur can use the Trident to control them, implying their sentience has de-evolved to that of the other sea creatures he can control.
- Blinded by the Light: Since they live exclusively in the deep sea, their eyes are very sensitive to light. They can be scared off by flares.
- Demoted to Extra: Downplayed, but they were Arc Villains in the New 52. Here, they are just another race of the Seven Seas.
- The Dreaded: Every single Atlantean who says their name does so with fear and horror. This contributes to the shock and awe impact of Arthurs arrival in the final battle when everyone realizes he commands them alongside the Karathen.
- Eldritch Ocean Abyss: Where they live; the Trench inhabit the deepest part of the ocean, and they happen to have evolved to match the horrifying dangerous creatures you typically associate with this trope.
- Evil Is Visceral: They have highly-visible ribcages and no lips, so their teeth are constantly on display.
- Fed to the Beast: Atlanteans sentenced to death are sacrificed to them. Queen Atlanna met her fate at their hands (or so it seems) and Mera tells Arthur that this would be her fate if she returned to Atlantis after rescuing him from the Ring of Fire.
- Fish People: Of the deepest and darkest variety. They are more beasts than people, actually.
- Human Subspecies: They're a human branch that evolved/mutated from ancient Atlanteans into monstrous creatures living in the darkest depths.
- It Burns!: They shy away from sources of bright light, whether out of fear or pain caused by extreme sensitivity to it. Arthur uses this to his advantage when fighting them, using emergency flares as Improvised Weapons and a means for him and Mera to escape from them.
- It Can Think: Just when it seems like Arthur and Mera might outrun them, a hidden smaller group rushes them head-on, showing that the Trench know how to hunt.
- Meaningful Name: They live in oceanic trenches.
- More Teeth than the Osmond Family: They're like humanoid versions of viperfish or angler-fish.
- Mutants: They have evolved (or de-evolved) from humans who once populated Atlantis to deep water monsters.
- Sea Monster: Based on the Deep Ones by H. P. Lovecraft.
- Spikes of Villainy: They're some of the most vicious characters with lots of spines.
- Was Once a Man: It's mentioned a few times that they used to be far more sapient before Atlantis sank. Having to adapt to the darkest part of the ocean took its toll on their minds and they de-evolved into monsters.
- Villainous Rescue: During the finale Arthur uses the Trident of Atlan to summon them to his aid.
- Xenomorph Xerox: Their mouth designs seem to borrow a little from the Alien creature.
- Zerg Rush: There are hundreds of thousands of them, and they attack in swarms.
Affiliation(s): Atlantis (in service of Orm)
A sea creature Orm uses as mount.
- Artistic License Paleontology: It lacks a fluke on its tail, its flippers are overly large, and its head is a bit too crocodilian, instead of the lizard-like head that the real animal had.
- Horse of a Different Color: Orm uses it as a mount.
- Living Dinosaurs: Well, sea lizard and not dinosaur, but still a specimen of supposedly extinct prehistorical species from the Late Cretaceous that lives in the oceans of present-day Earth, somehow.
- More Teeth than the Osmond Family: It has giant jaws and plenty of teeth, and Orm makes it bite everything in its way during the Final Battle.
- Palate Propping: Aquaman jams his trident in the creature's jaws during the Final Battle to avoid being eaten as they ascend to the surface.
- Sea Monster: Based on a real life prehistorical sea monster.
- Undying Loyalty: Noticeably stays loyal to Orm even when Arthur is controlling all other sea life that's not (sentient) Atlantean. It even tries to eat Arthur at Orm's direction.
- What Happened to the Mouse?: By the end of Aquaman its master has been defeated and is in royal custody, but it remains unaccounted for.
Affiliation(s): Atlantean Royal Family (King Atlan, then Arthur/Aquaman)
Played by: Julie Andrews (voice)
Dubbed by: Alejandra de la Rosa (Latin American Spanish), Élizabeth Chouvalidzé (Canadian French), Masako Isobe (Japanese)
A legendary sea monster from Atlantean myths. She guards King Atlan's trident in a cave in the middle of the Hidden Sea.
- All Myths Are True: It turns out she exists and isn't just the stuff of Atlantean myths.
- Because You Were Nice to Me: It's implied that Atlan won her friendship by using his powers to talk with her rather than fight her. And this is also implied to be the reason she joins Arthur in his fight against Orm.
- Composite Character: She's a combination of Karaku, the monster that ruled over the hidden realm that Atlanna was stranded in, and the New 52 version of Topo, as an octopus-crustacean hybrid under Arthur's command.
- Dark Is Not Evil: Her appearance may come off as scary, but she is a noble guardian, guarding her master's trident and waiting for the true king, she eventually sees Arthur as the true king and helps him in his battle against Orm.
- The Dreaded: She's very much feared by all the oceans, many citing King Atlan's own fear of her to be a major indicator of how dangerous she is.
- Fantastic Racism: Implied to have a hatred for surface-dwellers, spitefully referring to Arthur as a 'half-breed mongrel' and that he desecrates Atlan's resting place with his mere presence.
- Giant Equals Invincible: She's humongous, and she's impervious to everything Orm's armies throw at her during the Final Battle. She swats even Atlantean naval ships aside as if they're nuisances.
- Good All Along: After being described by several characters as an evil destructive force, she reveals herself as the guardian of the trident, and when Arthur proves himself Atlan's true heir by being able to communicate with her she lets him have it and even joins him in his fight against Orm.
- Half-Breed Discrimination: Spits bile-filled comments about Arthur's half-human heritage at him, such as saying she has never seen anyone less worthy than him. That's before she learns he can hear her.
- I Just Want to Have Friends: Everyone fears her, but all she really wanted was someone to talk with. Atlan was the only one who could until Arthur came along, and in between were aeons of loneliness.
- The Juggernaut: She is an unstoppable force of nature, and helps Aquaman put an end to the Final Battle.
- Kraken and Leviathan: Seems mostly based on such creatures, thus the name "Karathen".
- Knight in Sour Armor: She is contemptuous and world-weary, after centuries of being seen as a monster. She finds a confidant and friend in Arthur.
- Lightning Bruiser: Immeasurably strong and tough and still moves faster than Orm's armies.
- Mighty Roar: Lets one out during the acclamation of the new king of Atlantis, Arthur/Aquaman.
- Mix-and-Match Critters: She has tentacles to go along the kraken vibes, and they are the first thing we see of her. Her main body is mostly crustacean, and the shape of her head is vaguely reminiscent of that of some prehistoric fish.
- Nigh Invulnerable: She swims through lava, capital ship submarine plasma cannons just annoy her and even a flagship submarine's Wave Motion Gun does very little damage to her.
- Rent-a-Zilla: The most gigantic creature seen in the DC Extended Universe so far, while that setting is mostly about superheroes and not about kaijus.
- Samus Is a Girl: Only referred to as "it" whenever mentioned. When first encountered, "it" turns out to be female.
- Sea Monster: A very large, powerful, tough and fast creature of the deep.
- She's a Man in Japan: Karathen is voiced by a man in the European French dub.
- Threshold Guardian: Arthur is, by his own admission, a "blunt instrument" but he can't defeat her with brute force. It is only by communicating with her and expressing his heroic desire without pretense that he does truly become the Protector of the Deep.
- Time Abyss: She may very well be one of the oldest sapient beings on Earth, given that she was friends with Atlan himself, who lived many thousands of years prior to the events of the film.
- Undying Loyalty: Elected to stay with her friend, Atlan, during his self-imposed exile and stayed in his tomb to guard his trident even after he died in spite of how that would doom her massive self to its very cramped confines.
