|Role:||Utility droid owned by Binary Transports, Inc.|
While at the Junkard on Ryloth, RGE-3 was destroyed. As Highlife and Zulen Tek searched for replacement parts to rebuild him, they ran across some main parts for a Duwani Mechanical Products T3-Series Utility Droid, and a navigation module. Finding other various utility droid parts they decided to add the parts to their purchase as a side project for Zulen. After much practice on other droids, Zulen finally got around to building ZT-01. Thus Binary Transports, Inc. gained an astromech droid.
Because he's not really built from any one specific droid, he was dubbed "ZT-01" in honor of his creator.
See page 82 of the Knights of the Old Republic Campaign Guide for base stats. Zulen has added in a astronavigation module, plus some other TBA accessories.
