- "Blasted astromech's lost its mind!"
- ―Caibol, on R2-D2
Caibol was a human male who served Captain Raymus Antilles aboard the Tantive IV during the Imperial Era. When Antilles received supplies from the Gran Garsa, Caibol helped to collect the cargo. After the astromech droid R2-D2 attempted to attack the probe droid PTZ-1K, who had been attempting to send a message to the Galactic Empire, Antilles sent Caibol and Bonipa to take both R2-D2 and C-3PO for a memory wipe. However, R2-D2 escaped and returned to Antilles, informing him of the droid spy. When PTZ-1K attempted to send a transmission to the Empire, it was tricked by C-3PO into using an incompatible binary language, Caibol and Bonipa captured the droid.
