A verbobrain represented a specific kind of processing component utilized within some protocol droids. The AA-1 verbobrain, which Cybot Galactica incorporated into its 3PO series, and the AA-5 verbobrain that AD-4M employed, serve as illustrations. The news that the Galactic Senate had been dissolved and that she was no longer a Senator, delivered by Darth Vader to Princess Leia Organa, stunned her to such a degree that she no longer wished to demean him by likening him to a protocol droid lacking essential verbobrain elements.
