The enchanting world of Disney’s "The Little Mermaid" introduced audiences to a cast of unforgettable characters who brought the underwater kingdom of Atlantica to life. While Ariel is the undeniable protagonist, the supporting characters add depth, humor, and heart to the story, making the film a timeless classic.

The Core Trio: Princesses and Partners

At the heart of the story are three central figures whose relationships drive the narrative. Each character represents a distinct personality and motivation, creating a dynamic that resonates with viewers of all ages.
Ariel – The Curious Princess

Voiced by Jodi Benson, Ariel is the youngest daughter of King Triton and the catalyst for the entire story. Her insatiable curiosity about the human world leads her to make a fateful deal with the sea witch Ursula. As the first Disney princess to pursue a relationship based on mutual romantic love rather than political alliance, Ariel’s journey defines the film’s themes of self-discovery and sacrifice.
Eric – The Brave Prince

Ariel’s human love interest, Prince Eric, is portrayed as a kind and adventurous sailor. Though his screen time is limited compared to Ariel’s, his role is pivotal; his search for the mysterious girl who saved his life drives the second half of the film. The chemistry between Ariel and Eric, despite the obstacle of their different worlds, remains the emotional anchor of the story.
Flounder – The Loyal Friend
Despite his name, Flounder is a bright yellow tropical fish who provides comic relief and unwavering loyalty to Ariel. He is easily frightened but constantly pushes his comfort zone to support her. Flounder represents the steadfast friendship that helps Ariel navigate the challenges of her transformation and quest.

The Antagonists and Authority Figures
Not all characters in the ocean are supportive. The conflict in the story is fueled by a few key figures who embody fear, power, and the struggle for control.
Ursula – The Sea Witch

The primary antagonist, Ursula, is one of Disney’s most iconic villains. Voiced by the legendary Pat Carroll, she is a cunning and manipulative octopus who preys on the insecurities of others. Her design, inspired by the drag performer Divine, and her memorable song "Poor Unfortunate Souls" make her a character of terrifying charisma and dark humor.
King Triton – The Protective Father




















As the ruler of Atlantica, King Triton initially serves as the authoritarian figure who forbids contact with humans. His overprotectiveness stems from the loss of his wife, Queen Athena. Throughout the film, he evolves from a strict disciplinarian to a regretful and ultimately forgiving father, adding significant emotional weight to the story.
Supporting Cast and Comic Relief
The richness of the underwater world is populated by a variety of memorable personalities who contribute to the film's unique charm and atmosphere.
- Sebastian: The Jamaican-accented crab and royal court composer serves as Ariel's guide and often voices the voice of reason, though he is frequently ignored.
- Scuttle: A well-meaning but eccentric seagull who misidentifies human objects, providing some of the film's most laugh-out-loud moments.
- Chef Louis: The harried French chef of Prince Eric's palace who has a comical rivalry with Sebastian.
- Max: Eric’s loyal dog who plays a crucial role in the climax, showcasing bravery despite being a pet.
The Legacy of Character Design
The enduring popularity of these characters is a testament to the animation team's skill. Each character was designed to reflect their personality through movement and silhouette. Ursula’s massive frame and tentacles convey her menace, while Flounder’s rounded shape and big eyes emphasize his vulnerability and innocence. This attention to detail ensures that these characters remain instantly recognizable decades after the film's release, securing their place in the pantheon of Disney history.
