Species: Kryptonian war kite
Affiliation(s): House of El
Appearances: Man of Steel
A four-winged genetically engineered Kryptonian animal. It is used by Jor-El as his loyal flying mount.
- Aerial Canyon Chase: After stealing the Codex, Jor-El is chased on H'Raka's back by two of Zod's followers' small ships in a canyon. H'Raka successfully evades them, even causing one to crash on a falling big ship, but gets fatally injured by debris from an explosion.
- Bizarre Alien Biology: Ankylosaurus-like head, four wings and four legs with three fingers each.
- Catch a Falling Star: Catches Jor-El after his high altitude jump from the Genesis Chamber.
- Determinator: Serves its master very well and bravely to the very end, when Jor-El uses it to go to the Genesis Chamber to steal the Kryptonian Codex then to go back home. H'Raka doesn't flinch and does a wonderful job evading the fire of Zod's followers' ships through Krypton's canyons. It ultimately succumbs to its wounds upon landing at the House of El citadel but it has accomplished its mission.
- Horse of a Different Color: Jor-El basically uses it like a horse.
- Loyal Animal Companion: Even under fire from General Zod's followers' ships, this creature brings its master to the Genesis Chamber then back home at the cost of its life.
Species: Terrier dog
Played by: Cowboy the Dog
Appearances: Man of Steel
A dog once owned by the Kent family. He was the only friend Clark had as a child as the two used to play in the garden and fields of the farm.
- Canine Companion: The Kent family's loyal dog, and Clark's childhood friend.
- Happy Flashback: Hank is part of the most beautiful and carefree parts of Clark's childhood shown in Man of Steel. But he's also part of Clark's first major traumatizing experience, that is losing his father to a tornado, when the latter rushed to save the dog from it.
- Non-Human Sidekick: For the Kent family.
- Posthumous Character: Hank is long dead by the time Clark is in his thirties in Man of Steel, per a normal dog's lifespan. He is eventually replaced with another dog, Dusty.
Species: Border collie dog
Appearances: Man of Steel | Justice League | Zack Snyder's Justice League
The new dog owned by Martha Kent after Hank passed away.
Species: Spotted hyena (crocuta crocuta)
Appearances: Birds of Prey
A male spotted hyena pet Harley Quinn adopts after breaking up with the Joker. She purchased him from a back-alley animal dealer, who soon ended up being fed to him.
- Adaptation Name Change: Harley's hyena pets first appeared (like Harley) in the DC Animated Universe, and they are named Bud and Lou in it (as a Shout-Out to Abbott and Costello). Here, the animal is named "Bruce".
- All Animals Are Dogs: An extreme example. Really, you could replace any scene with him with a large, aggressive dog without changing anything else. On top of this, a German shepherd was used as Motion Capture stand-in for the hyena's special effects (and also because genuine domesticated hyenas are a nightmare to work with in Real Life).
- Angry Guard Dog: Not strictly speaking a dog, but very protective of Harley and Cassandra.
- Canine Companion: Harley adopts the animal in order to not feel too lonely after breaking up with the Joker, and treats him just like an ordinary dog as opposed to the hyena that he is (hyenas are more closely related to cats than dogs).
- Composite Character: As mentioned above, Harley originally had two hyenas as pets in the source material. They've been blended into one here due to CGI budget constraints.
- Cool Pet: There's no denying it's a most unusual pet.
- Disney Death: Seemingly gets killed when Harley's apartment is attacked with a bomb after she's been ratted out by the Chinese street food shopkeeper she rents it to... then at the end it turns out the animal just wandered in Chinatown and Harley is reunited with it.
- Dramatic Irony: Harley named him after "that hunky Wayne guy", aka Batman.
- Heinous Hyena: Averted. Other than eating the slimy (and possibly abusive) pet owner Harley took him from, he's pretty friendly, and after his "death" we later find out he was just wandering through Gotham for days and didn't hurt anyone (as far as we know).
- Right-Hand Attack Dog: Bruce is relatively calm and friendly for an apex predator, but his first act as Harley's pet is to eat the animal dealer after the man asks Harley for sexual favors.
- Serkis Folk: An odd case - a German Shepherd was filmed as a stand-in for him on set and a CGI hyena was digitally superimposed over the dog's motions. It's because the film's crew found out that hyenas are extremely difficult to tame and work with.
- Spaghetti Kiss: Harley shares a twizzler with him, in Lady and the Tramp fashion.
- Unusual Pets for Unusual People: While Harley is offered slightly more normal options, she picks a Hyena as her new pet.
- We Named the Monkey "Jack": Harley named the hyena "Bruce" after "that hunky Wayne guy", oblivious to the fact that she's crushing on her enemy.
Appearances: The Suicide Squad
Cleo Cazo/Ratcatcher 2's rodent companion.
- A Boy and His X: The loyal pet to Ratcatcher 2.
The Seven Seas
An octopus that can play the drums.
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.
- Attack of the 50-Foot Whatever: She is gigantic.
- 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.
- Curb-Stomp Battle: She completely blocks Arthur from the trident, and he's only able to touch it because she allowed it after she saw he could communicate with her. When he brings her to face Orm's army she steamrolls over anything in her path.
- 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.
- Evil Sounds Raspy: Inverted. She has a raspy, threatening voice as heard by Arthur, but she was a close friend to King Atlan, and supports Arthur in defeating his half-brother.
- 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.
- Historical Villain Upgrade: In-universe, the modern Atlanteans remember as a savage, destructive monster, that Atlan had to forcibly seal away. In truth, she and Atlan were friends, and she voluntarily isolated herself so as to guard Atlan's tomb, and the trident.
- 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.
- One-Man Army: Orm's army can't leave a scratch on her as she slaughters them.
- 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.
Appearances: Batman v Superman: Dawn of Justice
A monster that appears in another of Bruce Wayne's nightmares.
- Allegorical Character: Its presence is a visual representation of how Bruce Wayne has become consumed by darkness.
- Bad Black Barf: Constantly spews an inky substance.
- Blank White Eyes: Has these, to compensate for the fact that the scene has very few lighting, and to add scare factor.
- Looks Like Orlok: Ashen skin, twisted features and prominent front teeth. Appropriate considering its bat theme.
- Mythology Gag: It very much resembles Kirk Langstrom/Man-Bat, but has no known connection to him. Though, being a figment of Bruce's imagination, Langstrom may have subconsciously inspired its appearance In-Universe, provided that Batman has encountered him in this continuity.
- Prophet Eyes: Owing to being a creature of darkness, its eyes have deteriorated into cadaverous white orbs.
- Rule of Symbolism: In the nightmare, Bruce turns his back on a stain-glass window depicting an angel in a red robe descending to Earth. As he tends to his parents' tombs, the bat-creature bursts from his mother's and tries to drag him into the darkness.
