Lieutenant Reginald "Reg" Barclay is a talented but anxiety-prone Human Starfleet diagnostic engineer appearing across Star Trek: The Next Generation, First Contact, and Voyager. Initially mocked for his nervousness and holodeck escapism, he grew into a valued and resourceful officer.
Over his career Barclay survived a Cytherian intelligence enhancement, lent his name to a medical syndrome, met Zefram Cochrane, and, at the Pathfinder Project, devised the breakthrough that established two-way contact with the distant USS Voyager, earning honorary membership in its crew.
