PTZ-1K, also known as Peeteezee-Onekay or Peeteezee, was a Prowler 1000 seeker droid who was used as a spy by the Galactic Empire. PTZ-1K was placed aboard the a CR90 corvette to spy on the House of Organa, who were secretly operating against the Empire. While the protocol droid C-3PO was at first unaware of PTZ's duplicity, the astromech droid R2-D2 noticed the seeker attempting to access the communications array to send a message back to the Empire. With the help of C-3PO and R2-D2, Captain Raymus Antilles caught PTZ-1K, intending to wipe his memory.
