In the mirror universe, Daro is a Cardassian gul in the service of the Klingon-Cardassian Alliance during the late 24th century. In 2371, he commanded the scout ship Bok'nor. He was proud of his Cardassian sense of aesthetics, a sense he felt was lacking in his Klingon allies. He was especially appalled by the styles of clothing Klingons preferred to wear.
