A male human security officer serving aboard the U.S.S. Enterprise on stardate 5483.7 (2269), Lieutenant Carver accompanied Captain Kirk, Commander Spock, and Dr. McCoy to the surface of the second planet in the Taurean system after that world's transplanted female inhabitants lured the male contingent of the Enterprise's crew to their world. Like the rest of the landing party, the women drained Carver's life energies to dangerously low levels — their primary survival tactic — until a rescue party led by Lieutenant Uhura saved Carver and his teammates.
