Leonard "Bones" McCoy
Leonard "Bones" McCoy is the USS Enterprise’s chief medical officer, played by actor DeForest Kelley. Originally from Atlanta, Georgia, McCoy is a highly educated and efficient, but sometimes holistic, doctor most known for frequently using the phrase “I’m a doctor, not a (some episode-relevant descriptor)” to his leading officer, Captain Kirk. McCoy is sometimes portrayed as argumentative when he has doubts about the morality or safety of a situation. He is also known to be suspicious of 21st century technology and careful about when to approach an issue with tried-and-true human techniques rather than technological ones.
