Melody is a pretty, yet tomboyish 12-year old princess of average height and build for her age. She has straight black hair, most often tied back with a green hair tie in a low ponytail, pink lips, and blue eyes. Melody seems to have inherited a fairly even blend of traits from her parents. Most noticeable is her hair (the same color as her father's). She inherited her mother's eyes, nose and facial structure. It is also possible that Melody inherited Ariel's beautiful singing voice, which is heard in "For A Moment", a duet between Melody and her mother. Eric also gave her his skin tone, smile and thick eyebrows. For most of the film, Melody is seen in her underclothes, which is a separate pair of white pantalettes and a white camisole; the pantalettes cover the bottom half of her stomach. As a baby, she was wearing a cute and very pretty pink and white dress and her bow also has the same colors. While in mermaid form, Melody retains her camisole, but her pantalettes and legs are replaced by a red tail; her navel is also visible. It is odd that the merteens she meets don't pay notice she does not wear a typical sea-shell bikini top like other mermaids. She also has a pink ball gown and a yellow casual dress both with short puffy sleeves. Since she found it, she wears her locket that has her name on it.
Melody is sassy but well-mannered, and has respect for her mother Ariel and others. Melody's curious and tomboyish nature leads her to collect all sorts of items from the sea, a parallel to her mother at age 16. Melody's swimming proficiency and ability to hold her breath for long periods comes from her mermaid parentage. Largely because of her mermaid heritage, she was also seen as somewhat of an outcast, as evidenced by the guests at her 12th birthday celebration shunning her. She is also shy around boys, becoming quite flustered when a merboy she found attractive tried befriending her in Atlantica. She later met him again after the wall was disintegrated, with both recognizing each other.
Due in part to her partial mermaid heritage, Melody is a skilled swimmer. She also had inherited some of her mother's superhuman traits, namely speed and strength, the latter of which is demonstrated by her scaling an ice wall with little problems late into the film. She also inherited superhuman endurance, as evidenced by her not being crushed into oblivion when forcibly changed back into a human by Morgana despite the depth she was at. She also was able to speak to marine life.
AppearancesAriel and Eric are celebrating her birth, and have taken her out on a ship to meet with Ariel's father King Triton and six older sisters Aquata, Andrina, Attina, and Adella. Triton presents Melody with a locket which bears her name, meant to remind his granddaughter of her mermaid heritage. However, the celebration is interrupted by Morgana, Ursula's sister. Morgana kidnaps Melody and threatens to feed her to her shark, Undertow, if Triton does not hand over his trident. Though Triton almost does so and blasts Undertow with his trident by turning the shark into an anchovy, Ariel and Eric are able to thwart Morgana's plan. Morgana vanishes, but not before vowing revenge. Morgana is now a threat and until she is captured, Ariel decides that Melody can't know anything about the sea, including her mermaid heritage, Atlantica and her grandfather King Triton (which turns out to be a bad idea). She bans the merpeople from seeing Melody, and later has a large sea wall built to separate their castle from the sea. Meanwhile, Melody's locket is tossed into the sea.
Several years later, Melody grows up banned from entering the sea, but is ignorant of the reason why. Despite the ban, she loves the sea and regularly sneaks out to swim. This causes a difficult relationship between her and her mother. On her 12th birthday, while out swimming, Melody discovers the locket, but she is forced to get back to the castle as she has forgotten about her birthday party. Unknown to Melody, she is being watched in a crystal ball by Morgana and Undertow. Morgana takes this as the perfect opportunity to succeed at the one thing her sister Ursula never could. Later, while Ariel is helping Meldoy prepare for the party, Melody tries to tell her mother her true feelings about the sea, but are interrupted by Eric who leads Ariel and Melody to the ballroom.
During the party, Melody dances with a young prince, but trouble soon arises when Sebastian accidently ruins the dance and destroys Melody's birthday cake. Melody comes over to Sebastain to see if he's alright, but everyone starts to laugh at her for talking to crab. Humiliated, Melody runs out of the ballroom in tears and goes back to her bedroom where she again looks at the locket she found eariler. Ariel comes in to try and comfort Melody, but becomes distracted when she learns that the locket has her name written on it and opens the locket to reveal a picture of mermaids swimming in Atlantica. She confronts her mother about it, noting that Ariel has told her that Atlantica was only a fairytale. Ariel takes the locket away and is shocked to learn that Melody has been sneaking out into the sea. Enraged, Ariel forbids Melody from ever the entering the sea again. Hurt that Ariel refuses to give any answers, Melody takes back the locket and runs out of her room. Wanting to find answers about the locket and it's meaning, Melody takes a rowboat and runs away from home despite Sebastain's protests.
Meanwhile, Melody is lured to Morgana's lair by Undertow. Morgana uses a potion to turn Melody into a mermaid, which excites Melody. However, the spell will only last a few days. While on the ship, Eric watches as Triton transforms Ariel back into a mermaid by using his trident to search for and find Melody. Morgana explains that she can make the transformation permanent if she has the trident, which she claims Triton stole from her. Morgana asks Melody to retrieve the trident. Unknown to Melody, Morgana is lying and only wants the trident for her own selfish purposes. However, only a descendant of Triton can remove it from its resting place, and Melody is ignorant of Triton's connection to her.
While searching for the trident, Melody tries to use the map Morgana gave her and due to the ticklish sea kelp, the whale sneezes forcing Melody off of it and her map gets broken. Later on, she befriends a penguin named Tip and a walrus named Dash, and they join her in her search. The trio manages to sneak into the Atlantican royal palace and make off with the trident before Ariel, Flounder, Sebastian, and Triton arrive. On the way to Morgana's lair, Ariel and Flounder remind Scuttle to get to Triton and Sebastian. Melody returns to Morgana at the same time that her mother Ariel arrives. Ariel attempts to explain the situation, but Melody, angered at Ariel's decision to hide Melody's mermaid heritage, gives Morgana the trident.
Afterward, while revealing her true colors and the truth to Melody, Morgana takes Ariel hostage and traps Melody and Flounder in a cave by sealing the entrance with a thick layer of ice. She leaves them two to die and makes an ice tower where she fight Sebastian, Eric, Triton and the others. Soon afterward, Morgana's spell on Melody wears off. She reverts her human form, starts to drown and falls unconusius, but Tip and Dash get Undertow, Morgana's shark minion, to ram into the ice, and help Flounder carry Melody to the surface. There, she awakes. While Morgana is using the trident to make Ariel, Flounder, Sebastian, Triton, Tip, and Dash to bow down to her and is about to revive Ursula and her pet eels Flotsam and Jetsam, Melody realizes that now she can climb on Morgana's ice tower because she is a human now and has legs. She secretly sneaks up behind Morgana and takes back the trident, causing the other to be freed from Morgana's spell. Melody tells Morgana to stay back, but turns the wrong side of the trident to sea witch. Morgana grabs her leg and tries to take the trident back, but Melody stabs her in the tenticle with it. Melody then manages to toss the trident back to Triton, but gets pushed off the ice cliff by Morgana. She screams, falling to her doom, but Dash saves her in the last moment; she falls onto his soft stomach and survives. While catching his trident, Triton angrily confronts Morgana and imprisons her in a block of ice, telling her that neither she nor any of her family will threaten his family ever again.
Later, Melody has regained conscious and reunites with Ariel and Eric. Melody apologizes to her mother for all that has happened, but Ariel and Eric are the ones that truly sorry as they realize that they should've told her the truth. Melody explains that she never meant to hurt anyone, but thought she would be better at being a mermaid than a girl, her mother however explains to Melody that it's doesn't matter what she is, but assure's her that she and her father love her they way she is and express how proud they are of her. Triton and Melody then offically meet other and Triton offers to allow Melody to become a mermaid permanently or to stay with her parents and let things return to normal. Melody refuses the offer, instead choosing to destroy the sea wall, so that everyone, including Ariel, Eric, Flounder, Sebastian, Scuttle, Triton, Tip, Dash, Carlotta, Grimsby, Chef Louis, and Max the dog, could be together again.
