- "Maybe this tactical droid will tell us how they knew our plan."
TJ-55 was a T-series tactical droid who led an infantry detachment from the Separatist Droid Army during the Battle of Christophsis of the Clone Wars. This unit led a full battalion of B1 battle droids during the battle, which participated in an ambush against entrenched Republic forces on the basis of information provided by a traitor in the ranks of the clone troopers. A betrayal obvious to them, the Republic forces sought answers even as they retreated in the face of TJ-55's troops. As a gunship arrived to retrieve the survivors, a clone trooper decapitated TJ-55, hoping to use the data contained within his memory to expose the traitor.
