Doctor Ball

"It's only a matter of time before he breaks."

- Agent Kallus, after Doctor Ball's operation on Kanan Jarrus

Doctor Ball was an IT-O Interrogation Unit in service to the Galactic Empire before the start of the Galactic Civil War. Grand Moff Wilhuff Tarkin and Imperial Security Bureau Agent Kallus used Doctor Ball to torture the ex-Jedi Kanan Jarrus aboard Tarkin's Imperial I-class Star Destroyer, the Sovereign. The Imperials hoped to procure information from Jarrus, but the Jedi was able to resist giving away any information under Ball's operation.
