Dastagir was a Human man in Starfleet in the 23rd century. He served as a second engineer aboard the USS Enterprise, under the command of Captain James T. Kirk.
History[]
In 2270, Dastagir operated the transporter which beamed the Federation delegation down to Briamos, which consisted of Kirk, Spock, Hikaru Sulu and Nyota Uhura. However, a malfunction caused by pulsar damage accidentally resulted in a mind-to-body transposition: Kirk was in Sulu's body, Spock was in Uhura's body, Sulu was in Spock's body, and Uhura was in Kirk's body.
