Colonel Une is the militaristic half of Lady Une's personality. She was extremely loyal to Treize Kushranada, leader of OZ. Une was his personal assassin, having dealt with General Septum and Vice-foreign Minister Dorlian.
After she went into space to unite the colonies with OZ, her other personality made itself known. This personality- kind, peace-loving Saint Une- was loved by the leaders of the colonies, and they quickly joined OZ and turned against the gundams.
Lady Une's two personalities eventually combined, and she saved Duo's and Wufei's lives after realizing what they actually fought for. She was shot by Tsubarov, chief engineer of the mobile dolls, and was presumed dead. She survived, however, because of Tsubarov's terrible aim, and would have led a happy life with Treize, if it weren't for his untimely demise.
Lady Une was a woman of strength for her ability to handle herself in any situation, including the death of Treize; a weaker-willed woman would have given into hysteria and shamed both herself and her love. As it was, Une kept herself composed; something Treize would have been proud of, since he was always telling her to be more graceful.
