U-THR, also known as Uthre, was a protocol droid owned by a free-trader named Crimson. A 3PO Human-cyborg relations protocol droid, U-THR was of a slightly more bulky build than the standard 3PO model. It had the prissy character traits that were typical of 3PO droids. U-THR served aboard Crimson's freighter, the Starlight Red, where he kept track of the ship's sensors. Although finding Crimson a bit too talkative, U-THR was loyal to her and would do anything within his programming to serve her.
