Princess Ariel is the seventh and youngest daughter of King Triton and Queen Athena, rulers of the undersea kingdom of Atlantica. Ariel lived through much of her young life with a passionate - yet forbidden - admiration of the human world and longed to someday experience life on the surface.
Ariel is a bright, spirited, and headstrong mermaid princess with a strong passion for adventure and exploration. Her tendency to explore the more mysterious depths of the ocean (or more importantly, the world beyond the ocean) can lead to an array of problems for both herself and her friends, and in the confines of her personal life - as seen when she gets into an argument with her overprotective father, King Triton. Despite this, Ariel's selflessness, compassion, and intuitive way of thinking often resolve such problems, as she always takes full responsibility for her actions.
Ariel is extremely compassionate and loving towards almost all living things; more so platonically than romantically. This is most notably seen through her friendship with her closest companion, Flounder, and even her father's court composer, Sebastian, who, despite being against Ariel's recklessness and overly adventurous nature, is given a considerably large amount of love and respect from the princess, which is often reciprocated. With Flounder, she is comforting and patient, as well as protective, with the tendency to risk her own life for the guppy on various occasions.
