Bananya appears as a cute white cat with his upper body protruding from a banana peel-like lower half. Bananya has blackish brown eyes and two whiskers on either side of his face and pink cheeks underlying said whiskers.
Bananya is described as being optimistic and carefree. He behaves mostly as a normal cat would and has exhibited curiosity, playfulness, and even a cat's natural instinct to hunt small creatures like birds or mice. However, Bananya has been shown to overcome these natural instincts in favor of food or friendship (particularly sweets). His lifelong dream is to become a trendy chocolate-covered bananya.
