Poly is a parrot who appears among the animal companions in the anime Kimba the White Lion, known as Koko in the original Japanese version. His background begins in captivity, as he once belonged to the owner of a large hotel who treated him poorly, keeping him chained and striking him. Poly eventually gained his freedom and, in the course of his new life, encountered Panja, the white lion father of the series protagonist. He came to admire Panja deeply for his strength and kindness, and that admiration shaped his loyalty to the lion family. After Panja's death, Poly devoted his efforts to helping Panja's young son, Kimba, in whatever ways he could.

In personality, Poly is talkative, cheerful, and well-meaning, but also somewhat scatterbrained and prone to acting before thinking. He regards himself as knowledgeable and fancies himself a mentor and advisor to Kimba, even though his wisdom is often more apparent to him than to others. His good-natured and slightly gullible disposition makes him an endearing presence among the jungle animals, and he frequently provides lighter moments in the story. His time spent living among humans gave him some familiarity with human speech and customs, which he uses to assist Kimba and to bridge the gap between the animal world and the human world.

Poly's primary motivation is loyalty. He is devoted to Kimba and to the ideals that Panja represented, and he wants to be a useful and valued member of Kimba's circle. His role in the story is that of a close companion, occasional informant, and self-appointed adviser who supports Kimba through his struggles to lead the jungle. His relationship with Kimba is warm and affectionate, marked by genuine care even when his clumsy or overconfident behavior creates complications. He also interacts regularly with the other animal characters, often as a source of humor and chatter, and he shares a natural rapport with Kimba's other friends.

Over the course of the series, Poly does not undergo a dramatic personal transformation, but he demonstrates steady growth in his commitment to Kimba's cause. He becomes increasingly dependable as a helper, using his ability to fly to scout, observe, and carry messages, and his ability to speak some human language proves valuable whenever humans are involved. His notable traits are therefore his flight, his partial command of human speech, his familiarity with human behavior, and his determined, if sometimes misguided, sense of self-importance. Above all, Poly is defined by his loyalty to the memory of Panja and his earnest desire to see Kimba succeed.
