T3-M4
this ancient T3-series utility droid was created on the planet Taris some 4,000 years before the Battle of Yavin, modified to serve as a personal security unit. It was given light armor plating and upgradeable weaponry, and its programming was augmented for use in slicing into computer systems and breaking encryption codes. It was also provided with a variety of combat routines, many of which bent the rules about a droid's ability to harm a living being. T3-M4's owner was never publically identified, and its creator, Janice Nall, never told who ordered the droid. In reality, T3-M4 was originally designed for Davik Kang, but the droid was stolen by the courier who was employed to obtain it. Canderous Ordo had been chosen as the courier, but he managed to hire a group to purchase the droid before he could acquire it. Ordo then used the droid to slice into Taris' computer networks and steal the necessary codes for evading the Sith blockade of the planet. T3-M4 was later acquired by Carth Onasi and Revan, who used the droid aboard the Ebon Hawk during the search for the Star Forge. After the defeat of Darth Malak, the Ebon Hawk disappeared in deep space. With her hyperdrive damaged and Revan unaccounted for, the ship was adrift until T3-M4 and 3C-FD repaired the drives. After the ship was brought to Peragus II by Kreia, T3-M4 proved useful when Revan set out to escape from the facility, which had been attacked by an unknown force. Although T3-M4 valiantly helped Revan escape, the droid was badly damaged when it breached an emergency hatch that opened into the mines. T3-M4 managed to reach a repair station, and got enough of its systems back online to return to Revan and escape from Peragus II. After being stranded on Telos, T3-M4 was captured by Atris and the Haindmaiden Sisters, who spent time downloaded large portions of his memory core. T3-M4, in turn, managed to acquire a recording of The Exile's sentencing, as well as a list of all known surviving Jedi Masters. During The Exile's search for surviving Jedi Masters, T3-M4 was lost in a game of pazaak and eventually sold to Vogga the Hutt, who put the droid to work in his warehouse on Nar Shaddaa.
