Cophot was an Orion lieutenant (or bhar), who served as the executive officer and science officer of the Orion pirate ship that attacked and raided the USS Huron and was pursued by the USS Enterprise in the year 2270 (stardates 6334.1-6335.6).
He constructed an explosive device with which his captain could kill himself, James T. Kirk and trigger the destruction of both his vessel and the Enterprise. Cophot took command when his captain left, but when he was captured instead, he readily accepted the order for surrender and disarmed the self-destruct. He and the rest of the crew were captured by the Enterprise crew. (TAS episode & novelization: The Pirates of Orion)
