- The droid to Even Piell

This EV-series interrogator droid was inside the Seperatists prison, the Citadel, in the dungeon along with a few droid commandos where Jedi Master Even Piell was being held in around 21 BBY. He was interrogating the Jedi about the vital information on the Nexus Routes Piell knew about. When the Jedi refused to talk, the droid was moving to remove Piell's good eye using its build in needle. But all of a sudden, an elite team of Jedi and clone troopers burst in and destroyed the droid commandos before Rex fired at the interrogator droid, destroying it.
