Cursed by antagonist Doakudar's magic into a humanoid bird form alongside his entire village, Wataribe Kurama reluctantly serves as a spy within Wataru Ikusabe's party. His cooperation is coerced, traded for the promise of lifting the curse from himself and his people. He possesses tannish-brown feathers on his head and back, beige feathers on his front, an elongated beak, winged arms, thrush tail feathers, and three-clawed talon feet. His attire includes a fur-trimmed red vest, a gold belt, and blue overalls covering his talons. An eyepatch covers his right eye, later shown to conceal a zit, while his visible left eye is green. He typically carries a katana.

Initially, Kurama acts with obsequious deception towards Doakudar's forces, actively sabotaging Wataru's quest for legendary weapons like the permafrost sword and scorching heat shield. His loyalty is purely transactional, driven by desperation to save his village. However, through exposure to Wataru's group, he undergoes a genuine change of heart. He shifts from an unwilling antagonist to a trusted ally, demonstrating sincere concern and actively aiding the party's mission. While his specific role in later continuities like *Chou Mashin Hero Wataru* or *The Seven Spirits of Ryujinmaru* is not detailed, his core narrative arc remains consistent: beginning as a coerced spy, evolving into a reliable comrade, and solidifying his place within Wataru's team. His design inspired the character Duke L'Orange in *The Mighty Ducks* animated series.
