An Enterprise engineer who meets an image of Losira in the engine room in 2268, lies to her about the ship's systems and is killed by her touch.
John B. Watkins, engineer grade four, appears in the third-season episode That Which Survives. With Kirk's landing party stranded and the Enterprise hurled nearly a thousand light years away, Scott sends him to check a component in the matter-antimatter reaction chamber.
A woman he has never seen is waiting there. She asks him to explain the controls, and Watkins, suspicious, gives her a false account. She knows it is wrong, announces that she is for him, and reaches out.
He has time to shout a warning to Scott before her hand kills him. Dr M'Benga finds that every cell in his body has been disrupted. The intruder has also sabotaged the engines. Watkins was played by Kenneth Washington.
