Star Wars: Edge of the Empire
C3-T8 was a protocol droid that has been heavily modified. Many of its parts have been replaced with other droid models.
C3-T8 was heavily modified by its owner, Teemo the Hutt in order to properly meet the needs of its Master. The result is a Frankenstein of sorts with algorithms including protocol, supervisory, and combat capabilities.
The droid is rarely away from Teemo’s side and serves as one of his entourage and bodyguards as well as interpreter.
