This Star Trek: The Next Generation t-shirt features images of the counselor aboard the USS Enterprise, Deanna Troi. Lieutenant Commander Troi was assigned to the Enterprise-D as chief counselor in 2364. On the starship's first mission to Deneb IV, she was vital to Captain Picard in discovering the truth about Q and the Star-jellies captured by the Bandi. This was the first of many times that Troi proved herself to be an important crew member aboard the Enterprise.
