- “I consider myself a reasonable merman... I set certain rules and I expect those rules to be obeyed!”
- ―King Triton to Ariel
Triton is the ruler of the underwater kingdom of Atlantica, though his power has been implied to spread across the entirety of the sea. He is a muscular merman, the widower of the late Queen Athena, and the father of Aquata, Andrina, Arista, Attina, Adella, Alana and Ariel. He is also the father-in-law of Prince Eric and the grandfather of Ariel and Eric's daughter Melody. As King of Atlantica, he has in his possession a powerful magical trident which appears to be made of gold. It emits a glowing light and a typical sound when in use. Furthermore, he has a crown and two armbands, which also appear to be made out of gold.
His archenemy was Ursula, the old sea witch who was once a senior member of the Court of King Triton. For many years, she had been seeking a way to exact her revenge upon him for banishing her from the kingdom.
The reason for his constant clashes with Ariel, as told by directors Ron Clements and John Musker, is that he is very strong-willed and independent, like his daughter. Ariel is said to be Triton's favorite child, because as a child, he also had red hair and sees himself most in Ariel. The strong resemblance between Ariel and her mother, Athena, probably also plays a role in his favoritism.
The prequel film, The Little Mermaid: Ariel's Beginning, initially depicts Triton as a devoted and loving father and husband. After his wife's death, he becomes extremely strict due to the grief he suffered over his queen's death but eventually comes to terms with the incident, showing this by allowing music back into Atlantica after previously banning it in the wake of the tragedy.
The television series, set before the events of the original film, shows Triton to be a wise ruler. He is prejudice towards humans (possibly due to the death of his wife; despite the fact that Athena's death was an accident) despite the evident fact that merpeople are half-humans. Though he's constantly at odds with Ariel regarding humans and dangerous adventures, he has shown to have a large feeling of guilt and remorse for upsetting his beloved daughter.
In the original film, Triton is shown to be a caring father. However, his prejudice regarding humans often led to personality conflicts with Ariel. He is shown to have an explosive temper when provoked. It was also briefly implied that he may have had genocidal thoughts on humans in general, or at the very least didn't particularly care if a human ended up drowning, as when arguing with Ariel shortly after his discovery that Eric was saved by her, Ariel pointed out that Eric could have died if it weren't for her, with Triton unmovingly stating that it was "one less human to worry about" in response, despite confirming shortly afterwards that he doesn't even know what Eric is like. His explosive temper, when pushed far enough, was also shown to lead to violent acts, as he destroyed most of Ariel's human artifacts as a way to "get through to her" after the possibility of losing his daughter to the human world was brought into play. Despite this, he immediately showed remorse afterward, as his angered expression softened to one of despair. After Ariel goes missing (after becoming human) he blames himself for the situation and tirelessly spends his time searching for her, unable to rest until she's safe at home, showing he is able to admit when his aggressive actions, in spite of the reasonings, have gone too far. Earlier in the film, he also confided in Sebastian out of the fear that he may have been too strict with Ariel, showing a struggle in both keeping her safe and being a loving father.
By the time of the sequel, Triton has become accepting of humans. He has a notable soft spot for his granddaughter, Melody and highly values her safety. He's presented as still very wise, though incredibly toned down temper wise. However, his aggressive nature remains in times of crises.
Triton's supervising animator in the original film was Andreas Deja. King Triton is an old, large merman with bushy, light gray eyebrows and long, white hair. He also has blue eyes (and olive green in The Little Mermaid Ariel's Beginning). He has a thick, white beard and mustache and a widow's peak hairline. He is well muscled and wears gold gauntlets with several studs on them on each wrist. As a merman, Triton's lower body is that of a dark blue fish with cyan, translucent fins. As signs of his royal status, Triton wears a golden, five-pointed crown that resembles a sea star on his head, and carries the legendary trident, a golden, three-pronged weapon with powerful magical abilities.
In the original film, Triton is prejudiced toward humans and Ariel's fascination with humans casts a strain on their relationship. According to Triton, contact between the human world and the merworld is strictly forbidden.
Triton first appears at a concert in Atlantica, presented by the seahorse serving as the host. After Sebastian the crab, the distinguished royal court composer and Triton's loyal servant, is presented, Triton and Sebastian have a discussion about how they anticipate the concert due to Ariel, Triton's youngest daughter, is supposed to make her musical debut. But Ariel turns out to be absent, to Triton's extreme fury.
After an initial argument with Ariel over her latest trip to the surface, Triton orders Sebastian to keep an eye on her. When Triton learns that Ariel saved the life of, and fallen in love with, a human being, he loses his temper and, determined to turn Ariel over to his views of humans, destroys her collection of human things, completely ignoring his daughter's pleas to stop. In the aftermath, Triton, instantly horrified and remorseful over his actions, leaves Ariel tearfully alone in her grotto in shame.
Later on, after Ariel runs away from home in search of the sea witch Ursula, Triton orders a search for her to apologize for what he had done, unaware that she has accepted Ursula's deal and become a human. He asks Seahorse Herald if any sign of Ariel and Sebastian and he replies that they searched everywhere and no traces of them and Triton orders them to keep looking and no one sleeps until they return home safe and sound and he sadly did so. Triton is briefly seen suffering extreme remorse over what he had done, blaming himself for his daughter's disappearance.
When Sebastian, who had been watching over Ariel, arrives from the surface and tells the king about Ursula's scheme, Triton quickly goes out with Sebastian to find her. Ariel apologizes to her father, who attempts to destroy the contract between Ariel and Ursula, to no avail. Upon learning from Ursula that Ariel had signed an agreement with Ursula and that she may be willing to make an exchange for someone even better, Triton willingly takes his daughter's place, despite knowing the cost of his choice. Triton is temporarily transformed into a polyp, but after Ursula is destroyed, he is restored to his original form and regains both his crown and his trident, as well as his regal status.
By the end of the film, Triton has softened his attitude and realized that he had made a mistake by thinking humans were vicious and that he had been wrong in doing so. Upon noticing how much Ariel loves Prince Eric (who had destroyed Ursula and subsequently not only saved Triton's life, but also the entire kingdom of Atlantica) as much as she is loved by Triton, as well as considering Sebastian's statement "Children got to be free to lead their own lives", Triton transforms Ariel into a human once again, allowing Ariel to be with Eric. He is later seen at the wedding of Ariel and Eric, where he gives his daughter a heartwarming hug and accepts Eric as his son-in-law; when Eric bowed, smiling, Triton returned the smile as though thanking him for saving his life and the kingdom of Atlantica. After saying goodbye, he then uses his trident to cast a beautiful rainbow over the sky.
King Triton also appeared in The Little Mermaid animated TV series. According to the cartoon series, Triton was the son of Poseidon and the grandson of Neptune, of whom he had many fond memories. As a child, his nickname was "Red" for his red hair.
Although his anti-human sentiments remained, he could sometimes be persuaded to recognize his mistakes, such as when he apologized to Ariel for scaring her so much that she failed to return home after a human charm bracelet was accidentally locked around her wrist or when he was persuaded to help Ariel rescue a man trapped in a submarine at the bottom of the ocean (Implied at the end of the episode to be Hans Christian Andersen, who wrote the original tale).
He does seem to have some confidence in his daughter's abilities, as he once allows her to go and explore the source of a trail of pollution. He would later travel to the surface (said to be one of the first times he had been there), using his trident to create storms to drive the last bit of pollution away.
In the 1992 Disney Special "Sebastian's Party Gras", Sebastian and his performing friend, Sam Wright, are back for another spectacular show at New Orleans Square in Walt Disney World! Kids at home are invited to "Twist And Shout", join a "Conga Line" and do the "Limbo Rock"! Combining colorful animation and engaging live entertainment, "Sebastian's Party Gras" introduces the Little Mermaid's father, King Triton, who urges Sebastian to conduct his concerts under the sea only! But through the magic of music, the King changes his tune, learning that when you "Give A Little Love", "Life Is A Magic Thing" indeed!
Triton appears in the sequel, The Little Mermaid II: Return To The Sea. He seems to trust humans - or at least his son-in-law, Eric - by the time of this film. Upon the birth of Ariel and Eric's daughter Melody, he attends a celebration of her birth that takes place at sea. As a gift, he gives Melody a special locket that reveals a picture of Atlantica. However, his love for his granddaughter proves to be a weakness, which is exploited by Morgana, Ursula's younger sister. Morgana attacks the ceremony, desiring to avenge Ursula, and demands Triton's trident in exchange for Melody's safety. While Ariel and Eric are able to foil Morgana's plot, Ariel makes the decision to withhold all knowledge of Atlantica and mermaids for Melody's safety and Triton orders a search for Morgana and no one will rest until she is vanquished. A sea wall is put up around the kingdom, sadly cutting Triton off from his daughter and granddaughter.
Twelve years later, Triton is met at sea by Eric and Ariel, who explain that Melody has gone missing. Triton transforms Ariel into a mermaid to assist in the search. Triton and Ariel eventually find Melody with Morgana. With Melody ignorant of her true heritage, Morgana had convinced the girl that Triton had stolen the trident from her. Melody had been transformed into a mermaid and tasked with retrieving the trident, as only Triton or one of his descendants could remove it from its resting place. Despite Ariel's protests, Melody gives the trident to Morgana, resulting in an epic battle. Eventually, Triton is able to retrieve his trident after Melody steals it back. Triton then uses the trident to freeze Morgana in a block of ice, which sinks to the bottom of the sea. He then offers to allow Melody to become a mermaid permanently. However, she instead requests that he remove the sea wall, reuniting the humans and the merpeople.
In the prequel film, an opening prologue shows King Triton's wife, Queen Athena. The pair had a loving relationship. However, Athena was crushed to death by a pirate ship while trying to save the music box King Triton gave her as an anniversary present. Triton was so broken-hearted by her death that he banned music from Atlantica and forced everyone—even himself—to follow a strict daily schedule and it was the possible reason why he hated humans. Ariel's free-spirited personality is what casts a strain on their relationship in this film too, and he is particularly angered when he discovers that the leader of the (illegal) Catfish Club is, in fact, Sebastian, throwing his confidante into prison for this. He eventually comes to see the error of his harsh decisions, pardons Sebastian, lifts the ban on music and appoints Sebastian as his court composer at the end of the film.
In the film, Jim Cummings took over as the voice of Triton since his original voice actor Kenneth Mars was unavailable at that time due to health problems - Mars died three years after the prequel film's release.
He lost his wife (who was killed by a pirate) and developed a xenophobic grudge against humans as a result. He uses the voice talent of his daughter Ursula in order to lure sailor. However, she prevents attacks from the Jolly Roger, saving Captain Hook and his crew. Having a grudge against her father, she stole a magic bracelet from his vault, allowing her to become human. She becomes a pub singer and befriends Hook. However, this concludes a pact made with Poseidon to trap her singing voice within an enchanted shell in exchange for squid ink, for neutralizing his nemesis Rumplestiltskin. Instead, Ursula stole the ink from the vault for him just as her father arrives to take the procured item away. Angered that the ink has been crushed, Hook removed her voice so the King can never use her to sink another ship again.
Betrayed by Hook and developing a great dislike for humans as well as her own species, Ursula chose to no longer be a mermaid and used her father's trident to transform her fins into tentacles, thus becoming the Sea Witch.
King Triton made a few cameos in the series House of Mouse. In "Jiminy Cricket", he was seen sitting alongside Rafiki, Grandmother Willow and Merlin the Wizard. In "Salute to Sports", when Mickey said he wanted the audience to do the wave, Triton summoned an actual wave. In "Pete's House of Villains", Ursula was in charge at the reservation desk and refused to let Triton in the club. Instead, she morphed him into a polyp again.
Triton appears as a minor character in the novel by Serena Valentino. It's revealed that Ursula is his long-lost sister who was raised by a human fisherman after Triton abandoned her. When Ursula brings destruction to her old village to get revenge for them killing her father, Triton appears and tells her of their blood relation to each other. He brings her back to his kingdom but he is disgusted by her cecaelian form and tells her she could only live in his palace if she was in mermaid form, which adds a further strain in their relationship. He is shown to have no sympathy for any human because humans eat fish, and even tells Ursula explicitly that her adopted father deserved to die. When Ursula tells her story to the Odd Sisters, they grow a deep hatred of Triton and they agree to help Ursula plot his downfall. Later he is seen with Ursula giving up his freedom in exchange for his daughter's. After Ursula's death, he comes to realize that he treated her harshly and decides to make things right with Ariel and turn her into a human permanently.
King Triton plays a role in the Kingdom Hearts video game series, again as Ariel's overprotective father who openly berates the worlds outside the ocean floor. In the original game, he appears to have an impressive knowledge of the worlds outside Atlantica, despite said worlds supposedly being a secret. Triton also shows awareness of the Keyblade and its lore, proving he's been aware of the events of the Kingdom Hearts universe even longer than the protagonist Sora.
Triton makes his first appearance in the series' flagship installment, Kingdom Hearts where he forbids Sora, Donald, and Goofy from interacting with his world in their quest to find and seal the keyhole, knowing Ariel's fascination with worlds outside of Atlantica would lead her into trouble during the trio's mission. However, after Ursula causes havoc in search of the keyhole, as well, Triton leaves it in the hands of Sora, Donald, Goofy, and Ariel to stop her, eventually revealing the keyhole to be within Ariel's grotto.
In Kingdom Hearts II, the king's worries are switched from Ariel's obsession with the worlds outside of Atlantica, to the human world above the sea surface. To revert her mind from it, he asks Sora, Donald, and Goody to help Ariel instead focus on Sebastian's concert, in which she's set to sing in. Things take a turn for the worse when Ursula returns and attacks, taking over the sea and transforming Triton into a polyp. However, due to the actions of Prince Eric, the heroes are able to save the day, and the king, teaching Triton the surface isn't all bad, thus allowing his daughter access to the surface, as well as Eric's hand in marriage.
His role in the musical is similar to that of the original film. However, it also adds in a twist that Ursula is his sister (based on a deleted concept from the original film). It also reveals that the reason why he banished Ursula was because of her attempting to gain the Trident when she was inherited with the nautilus.
In The Little Mermaid: Ariel's Undersea Adventure, King Triton can be seen as an audio animatronic at the end of the ride, celebrating Ariel and Eric's wedding.
Triton also appears in the Disneyland park parade Paint the Night.
For the interactive attraction, Sorcerers of the Magic Kingdom, King Triton has his own spell card known as "King Triton's Trident".
Triton also appeared in the SpectroMagic parade with a lit up trident.
In Voyage of the Little Mermaid, King Triton makes a vocal appearance in the beginning of the show confronting Ariel about humans, voiced by an uncredited actor. Triton reappears in animation on screen with Sebastian speaking as he did in the end of the original film.
At the Disney's Art of Animation Resort, Triton's likeness can be found alongside other Little Mermaid characters as a 35-foot tall statue seen in the Little Mermaid courtyard.
- King Triton possibly based on Neptune, the Roman god of seas and earthquakes, the equivalent of the Greek god Poseidon.
- Since he is mentioned to be the son of Poseidon in The Little Mermaid animated series, he could, in fact, be the same Triton from Hercules: The Animated Series. However, the other Triton is more amphibious and resembles Hercules with green skin while King Triton is a merman known to have had red hair in his childhood. Plus, the same TV series also states that King Triton's grandfather was named Neptune, which wouldn't have been possible either way (as Neptune and Poseidon were the same mythological character, however Disney doesn't follow the Mythology 100% so it could be assumed they just chose those names due to them being the most popular for "sea king" names and they are the easiest to remember). Another possible explanation for this seeming discrepancy is that the names "Neptune", "Poseidon" and "Triton" are, in fact, regnal names that represent the traditional naming conventions of Atlantica's Royal dynasty. With this in mind, King Triton, his father Poseidon, his grandfather Neptune, and their ancestors are merely taking on the names of the original Olympian sea deities; much like the monarchs of many on-land kingdoms.
- The original Triton is from Greek Mythology, son of the sea god Poseidon, who had a fish tail and a frontal pair of horse legs, and sounded a conch shell when making a presence.
- Triton is one of only two parents of a Disney Princess to be featured in a large amount of marketing apparel and merchandise. The other being the Sultan.
- Contrary to popular belief, Ariel's Beginning does not indicate that King Triton hated humans as a result of Athena's death, as there was nothing indicating that Triton even held humanity responsible for her demise, and Marina del Ray surfacing at one point shortly after her promotion strongly implies that he didn't institute a ban on the surface. Despite this, the TV series Once Upon A Time simply indicates that King Triton hated humans as a result of Athena's death (albeit in the TV show the name Athena is not used and Triton is known as Poseidon).
- The Little Mermaid episode "Red" shows that he used to have bright red hair. When he reverts to his normal age, his hair lightens to auburn (as seen in the prequel), then orange, yellow, and finally white.
- In the Chip 'n' Dale Rescue Rangers episode "One-Upsman-Chip", there was a merman statue in a sea-based restaurant that strongly resembled King Triton. This could have been in honor of The Little Mermaid movie because this episode aired nine days after the film's release.
- In all the movies his eyes colors have been changing. In the first and in the second movie his eyes were blue but in the third they changed into green pistachio.
