Soon after his debut inStar Trek: The Next Generation’spremiere, Lt. Commander Data (Brent Spiner) became one of the show’s most beloved and enduring characters. A highly advanced android created by cyberneticistDr. Noonien Soong (Brent Spiner), Data was an invaluable addition to the USS Enterprise-D crew. Under the command of Captain Jean-Luc Picard (Patrick Stewart), Data saved the Enterprise and its crew numerous times throughoutTNG’sseven seasons.

Despite all of theandroid abilities that made Data superiorto humans, he wanted nothing more than to be able to experience human emotions. Throughout hisStar Trekjourney, Data observed and learned from the people around him, eventually developing his own kind of humanity. Like Leonard Nimoy’s Spock onStar Trek: The Original Series,Data offered an outsider’s perspective on humanity.Because of this, and because of Brent Spiner’s brilliantly understated performance, many ofStar Trek: The Next Generation’sbest episodescenter on Data.
