Dr. Leonard H. McCoy

Dr. Leonard H. McCoyChief medical officer aboard the original Starship Enterprise under the command of Captain James Kirk, who gave him the nickname Bones. As of 2267, McCoy had earned the Legion of Honor, and had been decorated by Starfleet surgeons. Early in his medical career McCoy's father was struck with a terrible, fatal illness. Faced with the prospect of suffering a terrible, lingering death, McCoy mercifully pulled the plug on his father, allowing him to die. To McCoy's considerable anguish, a cure for his father's disease was discovered shortly thereafter, and McCoy carried the guilt for his father's possibly needless death for many years. Prior to his assignment to the Enterprise, McCoy had been romantically involved with the future Nancy Crater. McCoy first joined the Enterprise crew in 2266, and remained associated with that illustrious ship and its successor for some 27 years. In 2267, McCoy suffered a serious overdose of cordrazine in a shipboard accident. In the paranoid delusions that followed, McCoy fled the ship, then jumped through a time portal being studied by Enterprise personnel. In the past, McCoy effected serious damage to the flow of time until Kirk and Spock followed him to restore the shape of history. In 2268, McCoy was diagnosed with terminal xenopolycythemia and chose to resign from Starfleet so that he could marry a woman named Natira, high priestess of the Yonadan people. McCoy rejoined Starfleet after a cure was found in the Yonadan memory banks. McCoy retired from Starfleet after the return of the Enterprise from the five-year mission, but he returned to Starfleet at Kirk's request when the ship intercepted the V'Ger entity near Earth. McCoy, along with Kirk, was wrongly convicted for the murder of Klingon chancellor Gorkon in 2293, a conviction that was later overturned. McCoy was scheduled to retire shortly after the Khitomer peace conference, but he either changed his mind, or later returned to Starfleet. As a retired Starfleet admiral, McCoy made an inspection tour of the Enterprise-D in 2364 at the age of 137.
