Koa (pronounced CO-əh) is General Mumble's wife and the other half of the Mumble Etc. label. She is a yellow pegasus with magenta eyes and a cyan-and-blue mane and tail. Her cutie mark is a stylistic depiction of Hatsune Miku's hairbands, due to her affinity for Vocaloid (and, a stretch though it may be, her love of music). Koa's music varies drastically in style, but mostly manifests within the realm of pop and accessible electronic.
