Merpeople/Disney

Legendary. Fairly tall, even in their human forms. Enchantingly beautiful and melodic voices, use them to lure and attract humans to send them to their demise, or simply to entertain them.
== Powers and Abilities ==
* Underwater Breathing: In order to live underwater, merpeople have the ability to metabolize oxygen from the water, which negates the need to surface to breathe air. However, they are more than capable of breathing air outside water, as evidenced by certain events where they are on land for prolonged periods of time.
* Aquapathy: They have a connection to their aquatic home, as they can communicate with aquatic and marine life.
* Speed Swimming: Mermaids can endure days of swimming without exhaustion, in such expertise and speed as to rival or exceed most sea life in comparison.
* Super Strength: Merpeople are often depicted with a degree of superhuman strength and abilities, which is evidenced by Ariel moving an underwater boulder from the grotto as well as knocking down a door with relative ease.
* Thermoendurance: They also have the ability to withstand and survive in extreme temperatures, such as when in a underwater volcanic region (such as Ursula's Lair) or the cold, Arctic icy waters where Morgana's Ice Cave is located.
== Appearances ==
=== Animated appearances ===
==== The Little Mermaid franchise ====
In The Little Mermaid and related media, merpeople are shown to live in the sea within various underwater kingdoms. Atlantica is the most prominent, though others are implied to exist in the TV series. They are shown to coexist with sea life, with whom they are able to communicate. They generally do not interact with humans, due to the danger, though this changes after the events of the first film. It also shows that many unnamed ones are held as prisoners of Ursula. They made bargains for her aid and were unable to uphold their part of it. As a result, they are withered down to polyps. Ursula's death causes them to be restored to their natural forms.
Interestingly, dialogue from one fish character in the TV series implies that most fish either don't realize or don't know that merpeople have parts of their biology that resemble that of a human, as it refers to them as "half-fish, half-something else". All male merfolks are unclothed to the waist, with the exception of the armored royal guards, while the adult and teenage females wear a pair of seashell bra; children, however, wear a bandeau top. Given the fact that the females cover their breasts, it is safe to say that their sense of decency is not much different than humans'. It is also possible that they are herbivores, or at the very least vegetarians, as they aren't seen eating fish, and apparently they don't seem to view doing so as being ethical.
==== Aladdin ====
One notable mermaid who appears in the series is Saleen, who is also referred to as a water elemental as she has the ability to control the surrounding waters as well as a variety of other aquatic abilities. One of her most prized possessions is a starfish that allows her to use various magical abilities. Her main associate is her octopus Armand.
Saleen being evil in nature, she makes several attempts to steal Aladdin for herself, from giving herself legs while trapping Jasmine underwater in "Elemental, My Dear Jasmine" to turning Aladdin into a shark in "Shark Treatment". It is indicated that there are other merpeople under the sea, as when Armand dyed Jasmine's hair to make it look like Ariel's iconic red mane, Saleen disdainfully mutters that she looks like every other princess under the sea.
==== Gravity Falls ====
Merpeople were briefly mentioned in "Dipper vs. Manliness" by the Manotaurs, and a merman named "Mermando" appears in "The Deep End". They are stated to live in the water.

In the opening credits, a picture of one like the one in the Mystery Shack can be seen at the end of the credits.
Merpeople prominently appeared in the episode "The Deep End" when Mabel Pines befriends a beautiful merman named Mermando. He had been swimming in the Gulf of Mexico but was caught by a net from a fisherman. He later is seen at the Gravity Falls Pool. When she first saw him, she went all silly, wanting him. She soon realizes that he is a merman, and thus tries to help him, of which she succeeds. He is last seen swimming back to his home. Merpeople have about 17 hearts.

=== Live-action appearances ===
==== Splash ====
In 1984, Disney released a live-action romantic comedy under the Touchstone label which was centered around a mermaid, played by Daryl Hannah. Taking the name Madison (and thus inspiring a great many real-world girls to do the same), she leaves the sea to seek out her beloved (played by Tom Hanks), whom she rescued from drowning. However, marine biologist Dr. Walter Kornbluth is convinced that mermaids are real, and will stop at nothing to protect his credibility by exposing her to the world.
==== The Thirteenth Year ====
In The Thirteenth Year, two merpeople are shown: the protagonist, Cody, and his biological mother. The ones in this film are somewhat similar in appearance to one from other media. However, there are several distinctions. They are able to pass for humans until they turn 13 when the fish physiology surfaces. The transformation is shown to be triggered by exposure to water. In addition to the fish-like tail, they also have scales on their palms and small fins that run along their forearms. They also seem to possess other abilities, such as the one to generate electricity, to the point that they can fire it similarly to a defibrillator, and the one to stick to surfaces.
==== The Chronicles of Narnia: The Lion, the Witch and the Wardrobe ====
In The Chronicles of Narnia: The Lion, the Witch and the Wardrobe, mermaids are depicted with brown-black hair, tan skin, and silvery fishtails with pink fins. They are seen near the end of the film swimming, leaping, diving, and laughing in merriment near the shores of Cair Paravel just before looping to the scene where the Pevensies are crowned as the rulers of Narnia as presented by Aslan.
==== Once Upon a Time ====
Mermaids are a humanoid species featured on ABC's Once Upon a Time, notable for having the ability to swim across realms. They are native to the Enchanted Forest and Neverland and first appear in the first episode of the third season. They are described as the most dangerous creatures in all the seas and are considered more of a threat than sharks, whales, or even a Kraken. Their powerful tails can break through wood and in large swarms they can sink ships. Mermaids can also use shells as trumpets to summon and manipulate terrible storms and waves. Some mermaids have voices which are lovely enough to enchant people and lure them onto rocks. Only four mermaids have been shown on the show, one being Ariel, Ursula before becoming the Sea Witch, another unnamed one, and an alternative version of Ariel from the Wish Dimension. Snow White also briefly turned into a mermaid.
=== Other Appearances ===
==== Sindbad's Storybook Voyage ====
Mermaids also appear in the Tokyo DisneySea attraction where they inhabit the Mermaid Rocks area.
In the pre-2007 revamp where it was known as "Sindbad's Seven Voyages", the mermaids were originally depicted as sinister sirens playing an enchanting but haunting song in which Sindbad did not appear in this version just before arriving at the Rukh Island area.
In the post-2007 revamp, the animatronic mermaids were redesigned to match the tone of the attraction's retool. In the current iteration, Sindbad's ship suddenly crashes during a storm just as the mermaids are heard harmonizing while Sindbad himself sings with the mermaids. After singing, Sindbad thanks the mermaids for helping him get a new ship just as he and Chandu sail to Rukh Island.
== Trivia ==
* In the Kingdom Hearts franchise, King Triton initially deduced that Sora was from another kingdom in the ocean due to his tail, implying that their tails act in a similar manner to human fingerprints (being unique), within the franchise.
* Shortly after King Triton defeated the Sorceress in the episode "Red", he mentioned to the Sorceress "See you next century," implying that their lifespans are over one century (100 years), at the very least. This has some basis in various real-life myths on Merpeople, with the original Hans Christian Andersen tale indicating that merpeople were capable of living for three centuries.
* In real life, the classification of merpeople is debatable due to possessing fish-like traits (namely fish-tails). However, the presence of mammary glands implies that they are mammals. In addition, their tails are patterned in a horizontal manner, more akin to marine mammals than true fish, whose fishtails are patterned vertically.
* A common claim was that merpeople were actually manatees or dugongs that were surfacing and had seaweed on top, causing them to be mistaken for them. The first part of the Disney Comics story "Serpent-Teen" alludes to this claim by having a manatee named Eddie pose as Ariel, implying that they have frequently used manatees as decoys to ensure they weren't discovered.
* The TV series adaptation of the film Aladdin features a siren water elemental named Saleen, which is similar to a mermaid. However, her fish features resemble that of a lionfish, and she possesses the power to manipulate water.
* Miss Piggy appears as a mermaid while she, Kermit and Robin performed "Octopus' Garden" in the episode of The Muppet Show James Coco hosted.
