"El patito feo" is an animated series produced by Spain's RTVE and directed by Josep Guardiola, adapted from Hans Christian Andersen's fairy tale. It first aired in 2000, comprising 106 episodes, each 26 minutes long. In 2016, a 75-minute theatrical version titled "El patito feo: La aventura inesperada," directed by Chinese director Zhang Changqing, was released, continuing the IP while incorporating sci-fi elements. The series follows the gray-feathered ugly duckling Fiel, who faces prejudice within the duck community due to his appearance. Through his friendship with his best friend, the piglet Nico, and his emotional entanglements with his crush, Patty, the story portrays his journey of staying true to himself. The theatrical version reimagines the main plot as an adventure of A Ni, a robotic duck from the moon, integrating sci-fi elements such as super-powered chips and interstellar pursuits while continuing the theme of self-identity [2]. Through humorous storytelling and a child's perspective, the work explores universal values such as friendship, prejudice, and identity.
