John Michael "J.D." Dorian, M.D., is a fictional character on the American comedy-drama Scrubs, played by Zach Braff. For his portrayal of the character, Braff was nominated for a 2005 Emmy Award and received three consecutive Golden Globe nominations in 2004, 2005 and 2006. J.D. is the narrator and main character of the series. He provides voice-over to the series which fills the roles of his internal thoughts and an overall narration in the show, often linking the story arc in each episode thematically.
J.D. has appeared in every episode during the first eight seasons except two season 8 episodes, "My Absence," in which he is only heard through a cellphone, and "My Full Moon".
Braff was a regular cast member for the first eight seasons, and appeared in six episodes of season nine to help transition the series into its new format.
J.D.'s name is based on that of Dr. Jonathan Doris, a college friend of creator Bill Lawrence. Doris serves as medical advisor on the show. According to Zach Braff, he feels that after seven years, there is not much of J.D.'s personality left to be explored, except for his relationship with Turk, while Lawrence has stated that the seventh season was to show J.D. finally growing up, in order to satisfy many fans who did not want to see him stay the same. However, Braff also says that J.D. has gradually evolved over the series, but cannot evolve too much at the same time as they need to "[give] the fans what they want, which is to see the characters be themselves."
