Cophot

Cophot was an Orion bhar, the executive officer and science officer of the Orion pirate ship that attacked and raided the USS Huron and was pursued by USS Enterprise.

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 command for surrender and disarmed the self-destruct.
