Sharp, previously known as NT-4012 but later identified as CT-4012, was a clone trooper who belonged to Breakout Squad throughout the Clone Wars conflict. His keen observational skills and sharp eyes led to him receiving the moniker "Sharp". His service included participation in the Mission to Kynachi. Subsequently, he and Jedi Master Ring-Sol Ambase were taken prisoner by the Confederacy of Independent Systems, and a Clawdite bounty hunter in the employ of the Separatists assumed his identity.
