"So they go there? Run? Get out in the sun? I wish I could be where these people are... I wish I could see them dancing."

Ariel is a mermaid, the youngest and most rebellious of the seven daughters of King Triton, ruler of the underwater kingdom of Atlantis. Her mother, Queen Athena, tragically died at the hands of humans, leading her father to impose a strict ban on all contact with the human world. Despite this, Ariel is completely consumed by an obsessive curiosity about human civilization. She spends her days searching for treasures from sunken ships, which she collects in her secret grotto, misinterpreting the purpose of ordinary objects—like a fork she calls a "dinglehopper" and uses to comb her hair, or a pipe called a "snarfblatt."

Her physical appearance is incredibly distinctive and eye-catching. She has thick, long, waist-length hair in an intense, vibrant shade of blazing red, which undulates dramatically in the water and frames her delicate face, with wide, expressive blue eyes and full red lips. Her skin is fair, and her slim, shapely waist is accentuated by a top made of two matching, light purple seashells. Her lower body consists of a shimmering, unique mermaid tail in a vibrant turquoise-green color, covered with smooth scales that grant her incredible agility and swimming speed.

Personally, Ariel is a dreamy, incredibly stubborn, impulsive, and daring romantic who struggles to accept the strict rules of her father's court. She often gets into trouble with her adventures, accompanied by her faithful, timid fish friend, Piglet (Flounder), and the crazy seagull, Scuttle, who explains the intricacies of "human science." She also possesses the most precious gift in the entire kingdom – a beautiful, angelic voice that inspires both admiration and envy. Her deep dissatisfaction with her underwater life and naive determination make her the perfect target for Ursula, the sea witch who lurks in the dark recesses of the ocean and watches her ever y move.
