In the mirror universe, General Rebecca Sullivan was a Terran female who lived during the 24th century. By 2377, she was one of the leaders of the Terran Rebellion and was in command of her own ship. She strongly objected to the rebellion's leader Miles "Smiley" O'Brien's suggestion that they launch an attack on the Klingon-Cardassian Alliance shipyard at Olmerak Prime as she believed that it would be a suicide mission. Furthermore, she confessed that she was of the opinion that the rebels should stick to their original plan of abandoning Terok Nor in spite of Bajor's secession from the Alliance and retreat to the Badlands.
