Zu-Zana was one of the robot hosts of the 2,001st century version of What Not to Wear on the Game Station satellite. The other was Trine-E. After attempting to find the right clothes for Captain Jack Harkness, they tried to remove his head. Zu-Zana could replace her arms with surgical devices, including a pair of scissors and a saw.
Unfortunately for them, Jack was armed with a compact laser deluxe (hidden somewhere "you don't wanna know", even though they had removed his clothing and, thus, any hidden pockets in the clothing with their defabricator). and blasted their robotic heads off. (TV: Bad Wolf)
Behind the scenes
The droid's name is a pun on that of Susannah Constantine, one of the hosts of the show at the time of Bad Wolf's broadcast.
