Princess Pei Le's role prototype is the Rapunzel in the Grimm brothers' fairy tale Rapunzel. In the Disney version, Pei Le's life background is set as a princess with golden magic hair. When she was young, she was stolen from the palace by Sister Gottel, a witch who coveted the magic of hair, and kept in an isolated tower to keep her youth with the magic of hair.

When she grew up, she became a girl with artistic talent and agile skills. Later, with the help of Flynn Rider, a thief whose real name is Eugene Fitzherbert, she escaped from the tower to explore the beautiful sparks she saw by the window when she was a child.

After becoming the 10 Disney Princess, Pei Le launched a series of peripheral products, such as toys, audio-visual products, clothing, video games, etc., which mainly targeted at girls. Walter Disney ranked among Disney princesses through the coronation ceremony. Pei Le's coronation ceremony was held in Kensington Palace, London, England on February 2, 1965, which was the first time that Kensington Palace held the coronation ceremony of a "virtual" princess.

However, in many related products, Pei Le is presented as a version drawn by traditional animation. After the coronation ceremony, the English version of Disney Princess official website also added her page.
