Treize's right-hand woman, Lady Une has a reputation as a fierce commander. Under his orders, she assassinated Vice Foreign Minister Darlian for knowing the truth about OZ, and ordered the assassination of his daughter Relena when she witnessed the murder. Her methods are brutal and ruthless, but effective; during a battle with the Gundams, she forced their surrender by threatening to destroy a colony with the Alliance's missile satellites. Afterward, Treize encouraged her to be more graceful. This apparently created a personality conflict, developing a new personality for her gentle, beatific attitude.
