Uni's HDD form. Like her sister, her personality changes to being strong and belligerent, and she gracefully wields a giant gun as tall as herself. The other CPUs and Candidates usually have a small increase in bust size when transforming, but, for some reason, Uni's bust shrinks down rather noticeably. She claims that they become "light-weight" so they won't get in the way of shooting her gun, but internally she's very bothered by it. Rom and Ram secretly call her their "flat friend."
