Tien Tubb was an elderly Sullustan male. Although nearly blind, he retained excellent hearing. He was a mechanic and scientist on Nar Shaddaa 3951 BBY, assisted by IT-31 and TT-32. Though disregarded by many, he was quite skilled, having created a renewable droid shield that could be raised and lowered a near-infinite number of times. Meetra Surik sought his aid in creating a new ID for the Ebon Hawk.
