He is a tanuki who, with his leaf, can transform to different forms such as an giant ox-like one and a bat-like one. He falls in love with Butterko and tries to win her heart.
Tanuki-Oni makes his first appearance as the antagonist in the Omusubiman short attached with the 1990 Anpanman movie. After that, he appears in the anime subsequently as a neutral character. (How often?)
