this was the nickname of a Level-One Security Droid C-3PO and R2-D2 meet on Hosk following the evacuation of the spaceport. Unit Zed was a SoroSuub 501-Z police droid, and he quickly gained the support of Threepio, Artoo, and a motley collection of leftover droids. Together, they manage to reroute a potential explosion on the station, as well as foil Olag Greck's attempt to steal a load of ash ore. They then pursued Greck across space to Nar Shaddaa, where Unit Zed was wounded by Greck's bodyguard, Xob, before he was destroyed by Forno. Droids - Rebellion states that Unit Zed is a fourth-degree security droid.
